Wow! What a year so far! There has been a lot of radio silence here on this blog since I was busy with my flight lead assignments at work (lead ADCO for SpaceX-3 cargo flight to ISS and then Expedition 40). Also, I am still very busy planning my wedding next month. I’m not going to try to catch you up on all the amazing and interesting things that have been going on in spaceflight year, for which I apologize. To partially fill the gap, here is a list of spaceflight industry news items that happened in August, helpfully compiled by Doug Messier of Parabolic Arc. Now on to more recent news.

Down to Earth

The crew of Soyuz TMA-12M returned to Earth on Wednesday, bringing to a close the long and eventful Expedition 40 onboard the ISS. I wonder if Swanny was happy to be home? Below is a video summary of their farewell, undocking, and landing.

Flight Engineer Reid Wiseman got this shot of the Soyuz re-entering.

Unfortunately, SpaceShipTwo will likely not have its first flight to space with Richard Branson aboard until at least early next year, according to Branson during an appearance on The Late Show. In just a few weeks it will be the 10 year anniversary of SpaceShipOne’s final flight which won the Ansari X Prize. Ten years later, the burgeoning “NewSpace” industry has not sent a single person to space. Let’s hope they are finally close.

On Thursday this week the first Orion crew module, which will fly an unmanned test flight in December, was moved from the Neil Armstrong Operations and Checkout Building to the Payload Hazardous Servicing Facility where it will be fueled. Perhaps “the gap” is slowly coming to a close?

In Orbit

With Expedition 40 complete on the ISS, Expedition 41 will start off with just a three-man crew of Alex Gerst, Reid Wiseman, and Maxim Suraev. They will be joined later this month by the crew of Soyuz TMA-14M, which includes the first female cosmonaut, Elena Serova, since Yelena Kondakova flew on STS-84 in 1997. So far, Alex and Reid are kicking off Expedition 41 by continuing to constantly post amazing pictures on Twitter as @astro_reid and @astro_alex. Why aren’t you following them?!

Last weekend on September 7, SpaceX successfully launched a Falcon 9 rocket carrying the commercial communications satellite Asiasat-6. The next Falcon 9 rocket on deck will hopefully launch on September 19 carrying a Dragon spacecraft full of cargo to the ISS.

Some high activity on the sun, including an X-class solar flare, is expected to bring some very nice aurora to people living in northern latitudes tonight and tomorrow. Look up!

Around the Solar System

The Rosetta spacecraft is in orbit around the comet 67P/Churyumov–Gerasimenko, arriving earlier this summer, 10 years after launch. This “selfie” is an amazing picture that shows both part of the spacecraft and the comet in the background. Rosetta will deploy the Philae probe to land on the comet later this year. ESA is expected to announce the landing site on the comet next week.

Not wanting to be left out, Opportunity also sent home a cool summer vacation photo from the rim of Endeavour crater on Mars. Yes, this is the same Opportunity rover that landed on January 25, 2004. That would be BEFORE the last flight to space by the NewSpace industry over 10 years ago, but who is counting?

China is getting in on the party too. It seems the Yutu rover is still alive on the moon and has sent back a recent panorama.

Down to Earth

In early January, Boeing announced that it will be leasing Orbiter Processing Facility 1 (or OPF-1 to NASA) near the VAB at KSC for launch processing of their X-37B spaceplane, which flies secret missions for the United States military. There are three OPFs at Kennedy Space Center. OPF-3 is already under a lease contract by Boeing for processing of their CST-100 crewed space capsule. CST-100 is one of three spacecraft (along with SpaceX’s DragonRider and Sierra Nevada’s DreamChaser) competing for commercial ISS crew transport contracts with NASA.

Speaking of the commercial crew contract, Sierra Nevada announced in January that they will be purchasing a United Launch Alliance (ULA) Atlas V rocket for an unmanned test flight of the DreamChaser in 2016. The launch would be from existing ULA launch sites at Cape Canaveral Air Force Station in Florida.

Also launching in 2016 is the first part of the European ExoMars mission. The core module of the European Space Agency’s (ESA) ExoMars Trace Gas Orbiter was delivered in Germany last month. ExoMars is a flagship ESA mission to explore Mars, which will consist of an orbiter, a lander, and a rover.

A LEGO model of NASA’s Mars rover Curiosity was launched in early January.

Since operations at KSC are ramping up for new spacecraft (like the Orion flight this fall) the VAB will be closing for tours on February 23rd. I am very happy to have seen space shuttle Endeavour in the VAB back in 2011.

The small town of Webster, adjacent to NASA’s Johnson Space Center here in the Clear Lake area of Houston, is planning an ambitious visitor center that will pay tribute to America’s space program and feature an 80-foot tall astronaut statue.

Former astronauts Jerry Ross and Shannon Lucid will be inducted into the astronaut hall of fame this year.

In Orbit

Up on the ISS, the first official Orbital Sciences’ Cygnus cargo mission arrived on January 12th. The private spacecraft is expected to stay another week or two before departing and burning up in the atmosphere.

Meanwhile, SpaceX had another successful Falcon 9 version 1.1 launch, putting a commercial payload into geosynchronous orbit. Their next launch is a Dragon cargo spacecraft on its way to the ISS, with a plethora of other launches on the manifest for this year. The ISS flight was recently moved to a March 16 launch.

Around the Solar System

On Mars, a big anniversary happened last month. January 4th was the 10-year anniversary of Spirit landing at Columbia Memorial Station and just a few weeks later Opportunity landed at Eagle Crater on January 28, 2004. Today, Opportunity is still trucking along at Endeavour crater, after driving over 35 kilometers since landing. Pretty good for a rover expected to live 90 days and drive maybe a kilometer or two.

There were a lot of NASA media events and discussions of the missions online. Universe Today put together a list of the top 10 discoveries made by the MER rovers. The Smithsonian National Air and Space Museum is running an exhibition on the MER rovers through September.

For some nice retro entertainment, here’s the landing video from 2004. Most of the exciting stuff is in the first minute or two, so you don’t have to watch all 8 minutes.

Opportunity is currently on the rim of Endeavour Crater – where she has been exploring since 2011. She has had some mild winter weather and is expected to make it through the solstice coming up in February. While exploring some rock outcrops at her winter stop point, Opportunity did a bit of a piroute and noticed something strange. In an area that had already been imaged by the rover, sat a new mysterious rock.

Leading theories initially were that it could be a fallen meteorite or ejecta from a meteorite impact somewhere nearby. Other theories are that it was simply dislodged by Opportunity’s wheels and simply “kicked” or dropped into the new location. An interesting mystery for the 10 year anniversary. Rove on, Opportunity!

Meanwhile on the other side of Mars, the younger but much larger Curiosity rover is navigating the “Dingo Gap” on its way to Mount Sharp and was currently parked atop a sand dune when I started to draft this post early last week. Nice view. Since then, Curiosity has successfully made it over the dune into the “valley” beyond. Curiosity is getting closer and closer to Mount Sharp, but spending lots of time stopping to do science along the way.

While waiting to cross the dune last week, the rover team released a stunning image of Earth in the Martian sky, as photographed by Curiosity on a clear twilit day. Beautiful.

Speaking of rovers, on the moon, the Chinese rover Yutu headed into its second lunar night in late January. Unfortunately, reports from the Chinese space program are that the rover suffered some kind of mechanical anomaly and is in danger of not surviving the two week “night”. It seems that some of the mechanical systems that are supposed to fold up the solar panels to provide thermal protection for sensitive components did not work properly. There has been no new news since the first reports more than a week ago. We will likely have to wait until “morning” on the moon (sometime next week) to know the rover’s fate.

Farther out in the solar system, the European comet-chasing spacecraft, Rosetta, has been woken up from hibernation. The spacecraft will be approaching comet 67P/Churyumov-Gerasimenko later this year and in an exciting and challenging mission will drop a lander onto the comet’s surface.

Out There

A new sensitive camera on the Gemini telescope in Hawaii took an impressive infrared light image of the distant planet Beta Pictoris b. This kind of direct imaging is certainly the future of exoplanet astronomy.

The NEOWISE mission (a re-purposing on the WISE infrared orbital observatory) has found its first near-Earth asteroid.

Astronomers at the European Southern Observatory were following up on an interesting binary star system, two brown dwarfs only a few lightyears from Earth, when data suggested that the star system contains a third companion, a jupiter-mass planet.  More study is expected to confirm the planet’s existence.

It’s been a busy of December since my last post. A hectic week at work, following the thermal pump malfunction on December 11th, kept me very busy right up until my vacation to visit family around Christmas for a week. I am back in Houston now and working on catching up on what’s been happening outside of my little world for the past few weeks. This post will be followed shortly by a 2013 year in review post, so stay tuned!

Down to Earth

On December 10th, NASA JSC’s Morpheus vertical take-off and landing test vehicle conducted its first free flight since the previous model was destroyed in August 2012. Very cool to watch.

Edit: and they flew another flight just a few days later on December 17th, which I missed when I first wrote this post.

On December 11th, Virgin Galactic’s SpaceShipTwo conducted a glide test in Mojave. More test are always good, but the frequency of glide tests without powered flights over the past few months was pretty much the nail in the coffin for Richard Branson’s prediction that he and his family would fly into space on the first suborbital flight on Christmas of this year. Clearly that didn’t happen. It seems likely however that Virgin will conduct another powered flight soon, possibly in the first week of January.

Doug Messier at Parabolic Arc is calling the first few days of 2014 “Launch Week”. Details on the various launches can be found over at his blog, but the quick summary is: SpaceX Falcon 9 commercial launch on Jan 3, Indian comm sat launch on Jan 5, Orbital Sciences ISS resupply flight on Jan 7, and a possible SpaceShipTwo flight.

Did you enjoy the movie Gravity? I liked it so much I saw it twice. Too bad the DVD wasn’t available for Christmas. Anyway, if you liked the movie, then take the time to watch this short behind-the-scenes clip that gives a glimpse at how some of the complex special effects were done.

The Las Vegas based company Bigelow Aerospace has put out a call for applicants to their “astronaut in-space simulations”. Basically the company wants to do their own independent look at how astronauts interact in closed quarters and also use the opportunity to improve their “crew systems” (in other words, the interior details of their inflatable space stations). Why not apply? Can’t hurt.

Be sure to go outside on January 3rd to look for the Quadrantid Meteors. They are supposed to be one of the best showers of the year, and this year the peak occurs on a new moon.

Astronaut Kevin Ford reminisced about spending Christmas in space during expedition 34 one year ago.

Folks are talking about Beyonce’s new song XO which opens with a sampling from the NASA broadcast of STS-51-L launch on January 28, 1986. The audio used is of the Public Affairs Officer reacting shortly after the shuttle Challenger was lost. The choice seems pretty tasteless and disrespectful, even if one can construe an ambiguous connection between the lyrics and the idea of a lost loved one. I personally can’t figure out if it is just a simple love song that has nothing to do with Challenger, or if it is intended to be something deeper. Listen for yourself.

In Orbit

The big news in orbit over the past couple of weeks was the malfunction onboard the International Space Station that led to two contingency EVAs that were prepared and executed right before Christmas. The issue also caused NASA to have to delay the launch and rendezvous of the second Orbital Sciences cargo flight to ISS, planned for a December 18th launch. The launch is now to occur in early January.

The summary of what happened is that on December 11th flight controllers started seeing anomalies in the ISS thermal cooling system. The problem was narrowed down to a faulty Flow Control Valve in one of the two pumps that flows ammonia to cool components on the outside of the station. Over the ensuing days, a few different teams were convened – one team was planning contingency EVAs to replace the pump, another was doing troubleshooting and thinking of ways to try to make the system work with the faulty valve, and another team was preparing a procedure to be executed in case the second pump failed (I was part of this team). After these teams worked night and day for over a week, it was determined that the pump should be replaced, and the first EVA was conducted on December 21st. The spacewalk was very successful; the pump removal went much better than a similar operation that replaced the same pump after a failure in 2010 during Expedition 24.

The second spacewalk was conducted on December 24th and left the station with a brand new pump and no more concerns about the thermal system for the time being. A potential third EVA was cancelled and the space station crew (and ground teams!) got a much needed break for Christmas.

The quick repair even allowed the Russian space agency to conduct their spacewalk that had already been scheduled for December 27th. One of the key objectives of the Russian EVA was to install some commercial cameras on the outside of the station. The purpose of the cameras is to make a live feed of Earth images, in fairly good resolution, available to the public. The cosmonauts got the cameras installed but they would not boot up, so they unfortately had to be brought back inside for troubleshooting.

Christmas 2013 is the 45th anniversary of an iconic photo taken by the crew of Apollo 8 while in orbit around the moon: Earthrise.

Earthrise

A team from NASA Goddard (with Andrew Chaikin for narration) put together a very cool (in an extremely nerdy way) recreation of how the image was captured that day (via Bad Astronomy).

Around the Solar System

On December 14th, the Chinese Chang’e 3 spacecraft came to a soft landing in the Bay of Rainbows on the Moon and quickly deployed the Yutu rover. Chang’e 3 is the first soft landing on the moon since the Soviet Luna 24 in 1976. Since that was over 37 years ago, almost 60% of the world’s population was not alive the last time there was an active rover on the moon. Emily Lakdawalla of the Planetary Society has been doing an excellent job, as usual, gathering information and compiling the best photos and video clips of the Chang’e 3 mission. Here is an update from December 14th and  from December 23rd, but I recommend just following her blog directly for the best stuff!

Very cool news from the Hubble Space Telescope; recent data in ultraviolet wavelengths reveals strong evidence of liquid water geysers coming from Europa, a frozen moon of Jupiter. Previously, water geysers have been imaged in visible light coming from Saturn’s moon, Enceladus. The images are stunning. Water geysers imply an ample supply of subsurface water (either in a vast ocean or just pockets or lakes in the ice) as well as the possibility for a medium for life, and a way for our spacecraft to sample that water without needing to drill deep into the ice. More science needs to be done to confirm the Europa geysers but the current data seems very compelling. Unfortunately, it is unlikely that the Juno spacecraft, currently on its way to Jupiter, will be able to confirm the geysers. This is because Juno’s missions objectives are related to the planet Jupiter itself, not its moons, and the visible light camera on Juno is more of an outreach tool than a primary instrument.

Lastly in planetary science news, the European orbiter Mars Express should have completed its very close flyby of the Mars moon Phobos by now. As Phil Plait writes, we don’t expect to get any close up pictures from the 27 mile flyby, but the data should help scientists nail down the exact mass of Phobos.

Down to Earth

Many space enthusiasts and planetary scientists were unsettled by a NASA announcement on December 3rd about a restructuring of the planetary science budget. In particular, the money allocated for planetary science grants is being reorganized into new programs – and half of that money will not be used for new grants in 2014. In short, this means there is less money available to scientists writing new proposals.

In other disappointing news, some vandals in Houston spray-painted graffiti on the side of the Space Shuttle mock-up Independence. Independence lived for almost 20 years at KSC where it was known as Explorer. The mock-up is displayed outside near the Space Center Houston parking lot, with no significant security at night (in contrast to the nearby Rocket Park which is behind a locked fence at night).

On December 3rd, NASA scientist and former JPL director Ed Stone was on Stephen Colbert to talk about Voyager entering interstellar space. At the end of the episode, Stephen Colbert surprised Dr. Stone with the NASA distinguished service medal. You can watch the interview here and the award presentation here (both links to the Colbert Report’s website and the clips come with ads).

On December 6, 1957 (56 years ago today), the Vanguard TV3 was the first attempted launch of a satellite by the United States – which ended in a spectacular explosion on the launch pad.

41 years later, December 4, 1998, the Space Shuttle mission STS-88 attached the “Unity” Node to Russia’s “Zarya” – the first step in what would be over 10 years of ISS assembly.

Thanks to a post from Parabolic Arc, I have bookmarked this interactive map from SpaceWorks Software that maps all planned, active, and former spaceports around the world.

Around the Solar System

According to Chinese media, the Chang’e 3 probe has reached lunar orbit. The lander is expected to make it to the surface on December 14th.

While we have seen imagery of Saturn’s mysterious North Pole hexagon before, the newly released images (and movie!) from Cassini is the highest resolution view yet, through multiple color filters. Pretty.

Out There

Astronomers using the Keck II telescope in Hawaii have taken images of 3 large (bigger than Jupiter) exoplanets. So few planets from other systems have been directly imaged that each new one is notable, even if the planets are unlikely to be habitable or otherwise remarkable. Phil Plait provides the images at the top of his post on the results.

SpaceX has purchased more land on the coast near Brownsville and South Padre Island in Texas, making their intentions fairly clear.

The United States Congressional Budget Office issued a report with options for reducing the national deficit. One option outlined includes completely eliminating all NASA spending on manned spaceflight. Oh dear.

In Orbit

The big news in the past two weeks, in my opinion, was the launch of Chang’e 3, a Chinese lunar lander. Chang’e 1 and 2 were successful moon orbiters, and the third mission, launched December 2nd, is scheduled to land a large rover on the lunar surface – the first to do so in 37 years – on December 14th. So far, China is putting their money where their mouth is when it comes to their spaceflight program.

Today, December 3rd, SpaceX launched a Falcon 9 version 1.1  with a commercial telecommunications satellite onboard. The SES-8 satellite was successfully sent on the planned geostationary transfer orbit – proving that SpaceX had sussed out and fixed the problem that marred an earlier test launch back in September. The failure of the upper stage to relight back on September 29 was traced back to frozen igniter fluid lines. As SpaceX points out in their press release, this mission is a big step towards fulfilling their long launch manifest, which includes many commercial launches, some requiring a geostationary orbit insertion. One more successful Falcon 9 v1.1 launch is needed for DOD certification. Also, the first ISS resupply flight aboard a Falcon 9 v1.1 is planned for early next year.

On November 19th, the robotic arm on the Kibo module of the ISS (the Japanese lab) was used to deploy several small “cubesats” into orbit. This is the second time the ISS has been used as a launching platform (last time was in December 2012 also using Kibo).

On November 20th, the International Space Station program celebrated the 15th anniversary of the first module launch – the Russian “Functional Cargo Block”, or more poetically “Zarya” (Sunrise)*. Here’s a short but amazing ISS timelapse to celebrate (via Universe Today).

*Nobody in Mission Operations at NASA JSC calls it Zarya.

Around the Solar System

The big story this past month (apart from recent Chinese success) has been comet ISON – the comet-of-the-century that wasn’t. ISON was a fun story to follow because the steep-diving comet (which grazed by the Sun at less than one solar diameter on Thanksgiving Day) was so dynamic that astronomers were having a hard time predicting how and when the comet might brighten, dim, or die. I had spent a week prior to perihelion (the name for closest approach to the sun) hoping I could get up in the morning and spot ISON before dawn, but the Houston weather would not cooperate. As evidenced by this amateur photographer, the comet was naked-eye in the right conditions. Anyway, ISON’s story ended shortly after perihelion, where the nucleus seemingly broke up in the extreme heat. The disintegrating rubble pile that emerged from the far side of the sun brightened very briefly, and is now dispersing and dimming, currently at 8th magnitude. As the writers at “Sky and Telescope” joke in their summary: “ISON now ISOFF”.

On December 1st, the Indian Mars orbiter Mangalyaan (now being referred to as “MOM” in all the english language media I follow) completed a successful rocket firing to leave high Earth orbit and go into solar orbit, on its way to Mars in September 2014. MOM is now cruising through interplanetary space behind NASA’s MAVEN orbiter, which successfully launched towards Mars on November 18th. Here’s a shot of MAVEN back in August when it was being readied for launch.

The European Exomars project – which consists of two missions in 2016 and 2018 – has chosen the name “Schiaparelli” for the 2016 lander. Schiaparelli was the Italian astronomer in the late 19th century who mapped Mars (and incorrectly deduced that Mars was covered in canals).

The Mars rover Opportunity (still roving almost 10 years after landing!) has found a winter post. Opportunity will hang out for the next 6 months on a north-facing slope called “Murray Ridge”. Murray Ridge is named after Bruce Murray, an influential planetary scientist from JPL who died earlier this year.

Out There

Astronomers have used the Hubble Space Telescope to detect water in the atmosphere of 5 “hot Jupiters” orbiting nearby (in galactic terms) stars. Since the planets are Jupiter-like rather than Earth-like, there is nothing Earth-shattering (or Jupiter-shattering) about the finding. However, future studies should be able to analyze the atmospheres of smaller and smaller worlds, leading us closer to finding a true Earth twin.

There is a new naked-eye nova in the sky. Don’t go running outside expecting to see something as bright as Venus – it is only magnitude ~5 and is not visible from Northern latitudes.

The Russian space agency and their cosmonauts successfully completed their Olympics PR stunt last week. On Saturday, November 9th, cosmonauts Oleg Kotov and Sergey Ryazanskiy took the 2014 Olympic Torch outside the space station and took some pictures.

After the symbolic handoff in space, the Expedition 37 crew from the Soyuz TMA-09M donned their Sokol spacesuits, climbed aboard their Soyuz, and returned to Earth early on Monday, November 11. Congratulations to Nyberg, Parmitano, and Yurchikhin on a great mission, and congratulations to the Russians on a successful orbital Olympic relay. Hopefully our space programs will get a bit of a PR boost as a result.

Expedition 37 with Olympic torch safely home

In heavier news, two space industry workers at the Plesetsk Cosmodrome in Russia died earlier this month in a propellant tank accident.

Two veterans of the Soviet space program died in the last month. First, Dmitri Zaikin, selected in the first class of Cosmonauts in 1960, died at 81. Zaikin never flew in space desite a long career in the program and being assigned as backup Voshkoh 2 commander. Second, Alexander Serebrov, from the second generation of cosmonauts, died at 69. Serebrov logged over a year in space on three separate missions, including flights to Salyut and MIR space stations.

The European Space Agency’s GOCE (Gravity field and steady-state Ocean Circulation Explorer) satellite recently ran out of fuel and crashed back to Earth, after a reportedly successful 4 year mission. Here is a cool picture of its re-entry over a remote part of the Atlantic OCean near the Falkland Islands.

In Orbit

On November 12th, Russia launched a satellite aboard a Proton Breeze-M rocket – the same type of rocket that crashed spectacularly back in July. This marks 3 launches since the crash, which is good news for the ISS program, which is supposed to receive a large new module called MLM aboard a Proton rocket.

In other launch news, SpaceX is scheduled to launch another one of their upgraded Falcon 9 version 1.1 rockets on November 25th, this time from Florida.

Around the Solar System

Continuing the launch news, NASA’s MAVEN Mars orbiter is set to launch on Monday, November 18th.

Mars rover Curiosity spent a bit of time in Safe Mode recently, but is back in full working order.

Comet ISON recently had an outburst and is now as bright as 5.5 magnitude. This should be visible with naked eye for people in dark sites (like my hometown Waikoloa, Hawaii) or keen observers with binoculars or telescopes in less dark areas. Keep in mind that there is a full moon late this week, however. Here are some helpful charts from EarthSky on how to find the comet. The comet is up in the early morning, as it is heading towards perihelion (closest point to the sun) in November 28. Most people are hoping the comet will be even brighter when it emerges from around the sun in December.

Sierra Nevada had an unpiloted glide and landing test of their DreamChaser space plane back on October 26th. Unfortunately, the left landing gear did not deploy on approach and the spacecraft crashed. The company quickly clarified that no major damage was sustained and they are looking into the mechanical cause of the stuck landing gear. The company has not released footage of the actual crash though. The video below cuts off just before landing.

Retired ISS commander Chris Hadfield’s new book “An Astronaut’s Guide to Life On Earth” is now on sale. I got my signed copy today here at NASA JSC! Commander Hadfield is back in Houston for a NASA checkup and is doing some book tour stops while here. Hope to read it and write a review soon!

November is a busy month for deliveries to the ISS. Last weekend, on November 2nd, ATV4 re-entered the atmosphere – undocking had been several days prior. A special experiment took place on ISS to get high resolution photos of the craft burning up and here are the results.

ATV4 re-entry from ISS

With ATV gone, we are gearing up for the arrival of the new ISS crew. The second half of Expedition 38 – Koichi Wakata, Richard Mastracchio, and Mikhail Tyurin – will launch from Kazakhstan on their Soyuz spacecraft on Thursday, November 7. As is the new flavor of Soyuz flights, they will arrive at ISS just 6 hours later. This crew is one of the most veteran-filled to share a Soyuz in a while. Wakata and Mastracchio will each be on their 4th spaceflights while Tyurin will be on his third. I expect that when Wakata returns to Earth, he will be the only Japanese astronaut on the top 50 list of most time in space (Which you can find about halfway down the page here).

The really exciting thing about this Soyuz flight is that it launches before the first half of Expedition 37 leaves ISS – which is usual how we trade out crews. Instead there will be a short period of 9 people onboard ISS for the first time since the end of the Shuttle program. Why are we doing this? So that an Olympic torch can be carried on a Russian EVA this weekend and then quickly returned two days later with the Soyuz TMA-09M crew. In order for this even to work, last Friday that crew climbed aboard their Soyuz in full re-entry suits and “relocated” their spacecraft from one ISS port to another. A lot of work for a little PR. We will see if it pays off.

Around the Solar System

On Tuesday, November 5th, India launched their Mangalyaan spacecraft to Mars. Mangalyaan is a Mars climate orbiter that will reach the red planet next year after a 10-month Hohmann transfer orbit. India’s mission is the first of two missions to launch int he current Mars window. NASA’s MAVEN mission is to launch on November 18.

Out There

I always like getting to talk hard science. There have been some great results regarding astronomy in the past few weeks:

First, astronomers from various universities collaborated on an observation that found the most distant galaxy ever imaged. The work was done at the Keck Observatory in Hawaii (shout out to my dad who does coding work at Keck on the instrument that was used!). The galaxy has an extreme redshift that puts it only 700 million years after the birth of the universe. Hopefully imaging the youngest galaxies will help us understand fundamentals of galaxy formation.

In exoplanet news, there are some developments. Planet Kepler-78b, which is a small very hot planet orbiting its star in just 8.5 hours – had its density measured (using the Doppler Shift method) and it was discovered that it is about the same size and density as the Earth. Most people are calling this the first actual “Earth-like” planet discovered in another solar system. However, it is still too close to its star to be habitable.

But even more exciting, perhaps, than this actual discovery of an “Earth-like” world is the statistical analysis (again using Keck data!) that shows that one-in-five stars in our galaxy is likely to have an Earth-sized planet in the habitable zone. Wow! You might be tempted to say “its just a statistical analysis” but really that’s all any estimate like this is ever going to be because we cannot get direct data on whether all 400 stars have planets. The more planets we discover, the better our sample size, of course. But right now it is looking promising that the follow-on missions to Kepler (JWST and others) have a high likelihood of directly imaging one of these sister Earths. We live in exciting times.

Two astronauts announced their departure from the NASA astronaut corps at the end of September – Ron Garan and Greg Chamitoff. Greg Chamitoff actually worked in my office as an ISS guidance officer, almost 20 years ago (although the ISS had not been launched yet at the time).

The J-2X upper stage engine, in development under NASA contract for about 6 years for use first in the Ares program and then on SLS, will apparently be “mothballed” next year. In other words, NASA has decided J-2X won’t work for SLS so it is going on hold until they find a future use for it. Bummer.

The European Space Agency is doing rover field tests in the Atacama Desert in Chile in preparation for their 2018 launch of the ExoMars rover.

Roscosmos – the Russian federal space agency – has once again replaced their head administrator in an effort to end the string of launch failures that has plagued the program over the past few years. Good luck with the new guy.

Speaking of Roscosmos; Russian media reports that they intend to try a new Phobos sample return mission (following their failed Phobos-Grunt mission in 2011). The new mission would not occur until 2020 or later. It bears repeating: good luck.

The SpaceX grasshopper test vehicle had one more test flight earlier this month – video below – which will apparently be the last. I have to admit that I am disappointed. I hope SpaceX has something more exciting up their sleeve; the Falcon 9-R might fit the bill.

The new company out of Tucson, Arizona known as “World View” intends to send paying customers to 30 km altitude in a balloon lifted capsule. The flights wouldn’t technically take tourists to space, but would give them a high altitude view of the Earth for far longer than flights in suborbital vehicles like SpaceShipTwo. Tickets are planned to only be $75,000.

In Orbit

Luca Parmitano wrote a nice blog post about what it was like to capture the Orbital Cygnus spacecraft last month.

A relatively large Near Earth Asteroid, 2013 TV135, was discovered on October 8th. TV135 has a diameter of about 400 feet and came within 4.2 million miles of Earth last month. The asteroid has another close approach in 2032 for which the probability of an Earth impact is 1-in-63,000.

Speaking of asteroids, on October 15 a Russian dive team found a half-ton chunk of the Chelyabinsk impact at the bottom of a lake near Chelyabinsk, Russia. Awesome.

Around the Solar System

On October 9, the NASA Jupiter probe Juno had a close flyby of the Earth to get a gravity assist and start heading to the outer solar system. Here is a view of Earth from Juno near closest approach. And here is a diagram of the spacecraft’s trajectory showing the affect of the Earth flyby.

The 2013 Mars launch window is coming up fast. First up is India’s Mars orbiter, currently scheduled to launch November 5. Then NASA’s MAVEN mission will launch on November 18.

Down to Earth

As most everyone is very aware, the US Congress did not come to a budget agreement for Fiscal Year 2014 before the calendar rolled over last week, so all parts of the US federal government that are affected by annual congressional discretionary spending have been shut down. This includes NASA. Some critical mission operations are continuing, including ISS operations and most active planetary exploration missions still have their control rooms staffed. The theme however is that anything not directly related to “real-time” operations has been halted. For the first few days this included work on missions in the pre-launch phase of the mission. Luckily for the MAVEN Mars orbiter, the next probe to launch to the red planet, they were able to get a special exemption so that they won’t miss their launch date this coming December.

The local government near Brownsville, Texas has agreed on how to handle temporary beach closures to allow for rocket launches, if SpaceX was to build a new commercial launch site near the Texas-Mexico border. The new legislation is not technically an approval of beach closures for this purpose, but is one step closer and should continue to drive SpaceX to pick Texas for their new launch site.

Ten year’s after China’s first manned spaceflight the CNSA is talking publicly about training astronauts from other nations. So if you got rejected from NASA’s  class of 2012 last year, maybe you will have better luck through this alternate means.

Or if you cannot get a passport to one of the nation’s that may partner with China, perhaps you should audition for NBC’s planned show “Space Race”, a reality show in which contestants can win a free ride to space on Virgin Galactic’s SpaceShipTwo. Neat – but not for me.

Last Thursday, the critically acclaimed film Gravity was released worldwide, and broke the October opening weekend box office record. I saw it with some friends at the first show at the nearest theater to NASA JSC, and was thoroughly entertained. The film is visually stunning and emotionally thrilling – go see it. It keeps an intense tempo with only a 90-minute run time (interestingly, the length of the orbit of the ISS, and an important time in the plot of the film). I am not going to post a bunch of links to reviews about the film because they are likely to be spoiler-ridden. You will enjoy this movie. Go. The trailers even give too much away. Just Go.

In Orbit

The anticipated test launch of SpaceX’s new Falcon 9 version 1.1 rocket took place on September 29th and delivered the Canadian payload CASSIOPE to its intended orbit. This is exciting and important news for the future of the company and their cargo contract with NASA. Unfortunately, one mission objective – to relight the second stage after shutdown – was unsuccessful. The company believes they can fix the anomaly before the next flight.

On the same day as the Falcon 9 rocket launch, the Cygnus spacecraft from Orbital Sciences finally rendezvoused successfully with the ISS, marking a big milestone for that company as well. Their next mission is tentatively scheduled for December, and would be the first official cargo mission of their contract.

Around the Solar System

Late in September, NASA finally declared the Deep Impact/EPOXI mission officially dead. After many weeks this summer of trying to regain communication.

NASA officially announced some scientific results from the Mars rover Curiosity which indicate there is little to no methane in the Martian atmosphere. The data seems robust, given that it comes from a sophisticated laboratory directly sampling the atmosphere for several months, but it contradicts previous intriguing science that pointed to an unexplained high level of methane in the atmosphere of Mars. This previous data had led some discussion about whether it could be a by-product of currently active Martian life. The press release from NASA offers no explanation of why the Curiosity data and the previous data (from powerful Earth-based telescopes and Mars orbiters) do not agree. I am not convinced that there isn’t something else going on here besides “Mars has no methane”…

NASA’s new lunar probe, LADEE, achieved lunar orbit yesterday, October 6. Let the science begin!
