Down to Earth

Hungary is the newest member of the European Space Agency (ESA). With the addition of Hungary and Estonia, ESA will need to revise their astronauts’ flag-covered shoulder patch (seen below on Andre Kuipers’ flight suit).

Since I mentioned ESA, it is always nice to share their Week in Images post.

The Intelsat 603 satellite, which was rescued to a higher orbit on the first 3-person EVA on STS-49 in 1992, has been disposed of in a “graveyard orbit”.

Eddie Redmayne, who won the Oscar for best actor last weekend, is a NASA supporter.

It’s a rare week that goes by without some news related to SpaceX worth mentioning. A few things this week. First, SpaceX has a new contract with SES for the launch of two communications satellites which may be the first to launch from the new facility in the Southernmost part of Texas. Secondly, SpaceX has started construction of their hangar near launchpad 39A at the Kennedy Space Center. 39A is one of the two historic launchpads built for the Apollo program and also used during the Space Shuttle program. Lastly, SpaceX will be launching their next Falcon 9 rocket in a few days. The current date is listed by Spaceflight Now with an uncertain “March 1/2″. This launch is of commercial payloads and will liftoff from Florida.

In Orbit

No notable rocket launches this week, except for a Russian military satellite on a Soyuz rocket, which launched this morning. Instead, there was another spacewalk up on the ISS. Terry Virts and ISS Commander Butch Wilmore have one more spacewalk this coming weekend to finish out their tasks laying cable for future commercial crew dockings.

Speaking of the ISS, the Russian Federal Space Agency (I’m not sure what to call it, as they are in the middle of a re-organization) announced this week that they now intend to continue ISS operations through 2024. Previously, Russia had only committed through 2020, so this is good news.

The Soil Moisture Active Passive (SMAP) satellite, launched by NASA on a Delta II rocket earlier this year, deployed its impressive sensing array this week and is getting ready to start its science campaign. Here’s an animation of what it would have looked like.

Meanwhile, out in the asteroid belt, NASA’s Dawn spacecraft is just a week away from entering orbit around Ceres, the largest asteroid. The pictures coming down are already remarkable and include a strange pair of bright spots in a crater.

A ceremonial groundbreaking ceremony at Cape Canaveral signaled the start of construction on a new crew access tower for eventual manned launches of the Boeing CST-100 atop United Launch Alliance Atlas 5 rockets. The tower is at Launch Complex 41, which is technically on Cape Canaveral Air Force Station, not Kennedy Space Center.

Also at the Cape in Florida, SpaceX has signed a lease with the U.S. Air Force to land Falcon 9 rocket stages at Launch Complex 13, which is currently not used for anything else.

The Mars One project has reduced their list of candidates for the first one way trip to Mars down to 100 candidates. If you forgot who Mars One is, they are the company that will air the last rounds of astronaut selection as a reality TV show as a way to fund their mission. However, you can color me skeptical whether that is a sound financial plan to fund a multi-billion dollar mission. Here is the list of 100 candidates from the Mars One website.

A recent poll reveals that most Americans apparently would not take a free ride to space.

Some more action up on the ISS last week. A Russian Progress resupply spacecraft launched from Kazakhstan and docked just 6 hours later.

Then on Saturday the first of three spacewalks of Expedition 42 went off with out a hitch when Butch Wilmore and Terry Virts spent almost 7 hours reconfiguring the front docking port of the ISS. There is a great detailed summary at AmericaSpace. The next spacewalk will be this coming Wednesday.

If you have heard the strange news about an unexplained “plume” seen high in the Martian atmosphere, you heard right. Astronomers aren’t sure what it is… could it be a high altitude dust storm or auroral activity? I hope they can figure it out!

Some good stuff from NASA’s astronaut office this week. First, the members of ISS Expeditions 48, 49, and 50 were announced. The crews have some veterans such as Jeffrey Williams and Peggy Whitson but also some rookies such as Katie Rubins and Takuya Onishi. Then, the Expedition 45 crew gave us this awesome mission promo poster.

Arianespace scooped some recent commercial launch contracts that SpaceX probably would have liked to win. Interestingly, the two companies each won 7 new contracts last year.

Items from a long-forgotten bag of odds and ends from the Apollo 11 mission are on display at the National Air and Space Museum in Washington, D.C. The bag was found in Neil Armstrong’s closet by his widow. You can’t make this stuff up!

It has been a busy week in space! On Tuesday, SpaceX brought home a Dragon capsule from the ISS and then a day later launched another Falcon 9 rocket, this time with NOAA’s DSCOVR spacecraft. The launch was at just about sunset making for some great pictures, which are all over the internet: Spaceflight Now has some good ones, or you can just browse Twitter.

Also on Wednesday, ESA launched a Vega rocket on a suborbital test mission of a small reusable spaceplane-like spacecraft (technically a “lifting body”). Watch how fast this rocket jumps off the pad!

The excitement extended into the weekend, with the departure of ESA’s last ATV cargo vehicle from ISS this morning. Here is the final status report from the ATV mission manager from prior to undocking. Unfortunately, the undocking was during orbital night so it is hard to find any good pictures. Here you can see ATV’s navigation lights shining in the darkness.

Next week a new Progress cargo vehicle will launch from Kazakhstan taking ATV’s place at the aft port of ISS. Then late in the week, Barry Wilmore and Terry Virts will step outside on the first of three upcoming spacewalks.

With such a busy and memorable week for ESA, it would be remiss of me not to share their Week in Images post!

And of course Terry and Samantha continue to take amazing photos of the Earth and post them quickly on Twitter for us to enjoy! Here is your weekly selection:

February 2nd is “budget day”: when NASA will announce the preliminary 2016 budget request for the agency as proposed by the White House.

Rookie European astronaut Andreas Mogensen has been posting video blogs of his training for launch. The latest entry is posted from Moscow and focuses on the Sokol spacesuit which is worn in the Soyuz.

The European Space Agency has a new unmanned spaceplane they plan to launch on a technology demonstration on February 11th. The IXV, or Intermediate Experimental Vehicle, has been undergoing launch preparations at the launch site in French Guinea.

Speaking of ESA, here’s their Week In Images, which is always a good click.

SpaceX has announced in a statement on their website that they are essentially dropping their lawsuit against the U.S. Air Force over the Evolved Expendable Launch Vehicle (EELV) contract which awarded 36 rocket launches to United Launch Alliance (ULA). SpaceX and USAF have apparently made a deal which allows USAF to honor current contracts with ULA but also work to certify SpaceX’s rockets soon and open competition to them for future payloads.

SpaceX also released a new animation to stir up excitement for the first test flight of their Falcon Heavy rocket later this year.

And in the last SpaceX news from last week, the company completed a static fire test on the launch pad in Florida in preparation for their next launch on February 8.

The Planetary Society has secured a launch aboard an Atlas V rocket this May for their LightSail solar sailing prototype. I am super excited for this mission! Check out this great video explaining the spacecraft.

In Orbit

Last week Wednesday, the ISS did a “deboost”, or an orbital correction maneuver to slow/lower the orbit. Usually we do reboosts to keep the orbit higher as the ISS is slowly degraded due to drag. In this particular case, the trajectory officers found a deboost the best solution for upcoming trajectory needs, and we had the extra propellant that we could afford it. I was lucky enough to be assigned the early morning shift on Wednesday to command the OPM (Optimized Propellant Maneuver) to spin the ISS around in preparation for the burn – which went well later in the day.

ISS astronauts got some nice photography of the blizzard that hit the US east coast last week:

And here is a selection of a few other great shots from ISS over the last week. If you want to follow Twitter posts from the ISS, follow my list, “people in space,” which I will always have updated with any astronauts who are tweeting from ISS.

Three launches occurred in the last week, bringing this year’s total up to 5 launches. NASA’s Soil Moisture Active Passive (SMAP) Earth-observing satellite was the third launch of the year – and third from the US – but almost didn’t beat a Japanese launch and then a Russian launch due to a scrub first for weather and then for technical issues. They finally got off the ground from Vandenberg Air Force Base in California on Saturday morning. Here’s a video.

The other two launches were this morning, Sunday, February 1st. Japan launches a spy satellite on an H-2A rocket (the same rocket that sends the HTV cargo vehicle to ISS) and Russia launched a communications satellite on a Proton rocket from Kazakhstan. This was the 5th successful Proton flight since their most recent failure last May.

Newly released high resolution images from the Rosetta spacecraft reveal a rather large crack in the comet 67P/Churyumov-Gerasimenko. Could the comet split in two when it gets closer to the sun? Exciting!

The image release also included some new shots of the Philae lander descending to the comet from the perspective of the orbiter.

Last Monday a rather large asteroid named 2004 BL86 flew by the Earth at about 3 lunar distances (750,000 miles). The asteroid is 325 meters (1,066 feet) in diameter and has a tiny moon! Check out this radar imagery from NASA’s Goldstone antenna:

As NASA’s Dawn spacecraft gets closer and closer to the solar system’s largest asteroid, Ceres, it is now returning images of the world that are better than what Hubble has shown us in the past.

Last week SpaceX secured a $1 billion dollar investment from Google and Fidelity. Google’s interest in the company is supposedly tied to their plans for an Earth-wide satellite internet system.

Orbital Sciences has signed a contract with RSC Energia (the Russian state-owned corporation which includes NPO Energomash) to purchase enough RD-181 rocket engines to power 10 Antares flights. The engine replacement is needed to replace the AJ-26 engines which are implicated in the loss of an ISS cargo resupply mission last October.

British singer Sarah Brightman has started her cosmonaut training in Russia. She will launch to ISS for ten days later this year.

If you aren’t on Google+, one reason to join is to follow Samantha Cristoforetti’s posts from the ISS. She posts almost-daily updates on how her mission is going, which is a pretty good read. Her most recent posts include a summary of the false emergency last week and a cool student robotics competition they hosted onboard.

Elon Musk released photos on his Twitter feed of the moment that the SpaceX Falcon 9 rocket first stage hit their “autonomous spaceport drone ship” (see, barge) and blew up. This occurred a few minutes after the launch of the latest Dragon resupply craft last Saturday. It seems like they hit their target but came in too hard. Maybe better luck on their next flight in a couple of weeks.

Update: Just a little while after I wrote this post, the SpaceX twitter account posted this amazing Vine video.

NASA completed a “hot fire” test of the new RS-25 liquid fueled engine at Stennis Space Center in Mississippi. The RS-25 is a modified Space Shuttle main engine which will power the SLS.

Much noise has been made about Ted Cruz (R-TX) being assigned to a US Senate subcommittee that oversees the budget of NASA. The main concern is that Cruz is considered anti-science. At the very least, he is anti-science when it comes to climate research, which NASA supports with a fleet of Earth-observering satellites. Houston Chronicle has the best analysis I have seen of what impact Cruz may actually have on the NASA budget. If you are concerned about this topic, you should read Eric Berger’s post. Here’s a longer more technical analysis at Space Policy Online.

Virgin Galactic is teaming up with a small satellite company known as OneWeb to launch a large constellation of satellites to bring broadband internet to the entire world. Replacement satellites will be launched by the LauncherOne rocket dropped from Virgin’s WhiteKnightTwo carrier aircraft.

There is an idea floating of a new reality show which would be a competition between inventors and scientists to get their research flown to ISS. Sounds cool!

Two big things happened on the ISS this week. on Monday, the latest SpaceX Dragon resupply craft arrived. This was the first cargo delivery to ISS from the US since the loss of an Orbital Sciences Antares rocket in October. There was one Russian Progress resupply flight back in November.

The SpaceX flight was quickly overshadowed by an emergency alarm onboard the ISS on Wednesday morning. The alarm was for a toxic leak of ammonia, which cools the space station avionics hardware in fluid loops on the outside of ISS. In certain failure cases (for which there is multiple layers of redundancy to prevent) the ammonia can break into the internal fluid lines (which carry water) and endanger the astronauts.

Ground teams and the astronauts took immediate safety actions, as we train for hours and hours for, and evacuated to the Russian side of the space station, which does not have ammonia coolant lines. The emergency alarm was eventually determined to be false, caused by a computer glitch, and the astronauts were allowed to open the hatch to the rest of the station late in the day on Wednesday.

While the astronauts are safe, cleanup from such a major (potential) failure takes some time because of all of the automatic safing software that shut down ISS systems on Wednesday. The Flight Control Team will still be diligently working towards bringing the ISS back to “nominal” during my evening shifts this weekend.

Around the Solar System

NASA’s New Horizons probe has technically begun science operations for its Pluto encounter, although it is still more than 100 million miles from Pluto.

The long-lost Beagle 2 lander has been found on Mars by NASA’s Mars Reconnaissance Orbiter (MRO). The lander was lost during EDL phase (Entry, Descent, and Landing) back in 2003, which was a huge disappointment to the United Kingdom’s space agency. Incredibly, although the world had assumed that Beagle 2 crashed into the surface – hence the loss of communication – the MRO images show the lander safely on the surface, partially deployed. In honor of deceased mission designer John Pillinger, I think this image deserves an update to show that Beagle 2 made it to the surface.

As of Friday night, the next SpaceX Falcon 9 rocket to send a Dragon capsule to the ISS is still on the ground. But the issue that caused launch abort on Tuesday has been dealt with, and the SpaceX launch team is busy prepping for another attempt in just a few hours. Launch is scheduled for 4:47 AM Eastern, Saturday, January 10th. I will be getting up to watch mostly because of the crazy attempt to land the first stage on a barge… I mean autonomous drone ship.

At the Smithsonian’s National Air and Space Museum on the National Mall in Washington, D.C., a new exhibit just opened called Outside the Spacecraft. The exhibit celebrates 50 years of Extravehicular Activity (EVA) which started with Russian Alexei Leonov’s first spacewalk in 1965.

The Chinese rocket that launched on December 31st was only carrying a Chinese weather satellite – not super exciting. But check out these incredible images of the first stage of that rocket, which appears to have landed in the middle of a road in a rural Chinese town. I am glad that in the US we have more concern about where our spent rocket stages end up…

The SpaceX Falcon 9 rocket that was supposed to launch to ISS Tuesday is still stuck on the ground. A problem with a hydraulic actuator for the second stage’s Merlin 1D engine lead to a launch scrub. They will try again on Friday, January 9th. Here are some shots of the rocket on the pad.

In a pretty awesome outreach move, Elon Musk did an “Ask Me Anything” hour on the website Reddit on Monday night (on the eve of their launch attempt). Here is the link to the whole thread, or you can read some highlights at Parabolic Arc.

The new SpaceX launch site at the extreme southern coast of Texas is likely going to seem more and more real throughout 2015. Just this week, SpaceX has begun posting job openings for the new location near Brownsville, Texas.

Richard Branson wrote a blog post about his thoughts in the immediate aftermath of the SpaceShipTwo accident, and his continued resolve to move forward with Virgin Galactic. As always, Doug Messier has some excellent commentary and dissects Branson’s writing.

The US Government Accountability Office has denied Sierra Nevada’s protest regarding the awarding of the CCtCap contract for commercial crew flights to ISS. That means that NASA’s decision to fund only SpaceX and Boeing will stand.

The Atlantic had an extensive feature article about the ISS titled “5,200 days in space: an exploration of life aboard the International Space Station, and the surprising reasons the mission is still worthwhile.” It is one of the most compelling stories covering the ISS that I have ever read.

Surprisingly, at about the same time, Time ran a cover article about Scott Kelly, who will be launching in March for his one-year stay aboard the ISS. It is also a very good story that touches on the human side of life in space.

And of course, our friends in orbit continue to dazzle us on Twitter with views from orbit. Here is a sampling.

The Mars Exploration Rover Opportunity is getting very close to the summit of Cape Tribulation on the rim of Endeavour crater. It amazes me every time I read an update on Opportunity that the mission is still going and still so successful 11 years later! (Edit: and here is a more detailed MER update from the Planetary Society blog)

On the other side of the planet (Mars that is) Curiosity has made some exciting discoveries. The rover has proven the existence of organics in the rocks of Gale crater and also that there is detectable concentrations of methane in Mars’ atmosphere. The methane is important because, due to chemical reactions that must necessarily occur, the methane is transient – meaning something is producing it. A very detailed discussion of this new finding is at the Planetary Society blog. The research was also published in the journal Science.

Out There

The Kepler team announced yesterday that a number of newly confirmed planets (based on old Kepler data) brings the total exoplanets discovered by the space telescope to 1,000. 8 of these new worlds can reasonably be considered “Earth-sized” and even in their stars’ habitable zones. Because we don’t have details on their composition or atmosphere, we can’t actually know how likely it is that life could live on these planets. But, as Phil Plait writes, this is further confirmation that the universe is full of small planets. Eventually, we will find Earth’s twin.

I am continually puzzled by large-scale aerospace projects using crowdfunding sites. In the latest installment, a company called Bristol Spaceplane (who have apparently been around at least since the Ansari X Prize days) is looking for 10,000 GBP (that’s about 15,500 USD) to build a remote controlled scale model of their spaceplane concept (via Parabolic Arc). How they intend to turn $15,000 of crowdfunding into a multi-billion dollar spaceplane project is not mentioned on their fundraising page.

SpaceX has picked up a Qatari telecommunications launch for 2016, adding to their already packed manifest. The Falcon 9 launch rate will be one of the big stories to follow in 2015. SpaceX is still on track for a January 6th launch to resupply the ISS.

In some continued minor fallout from the Virgin Galactic accident earlier this year, a company called Virool (I hadn’t heard of them) has changed up the prize in a previous contest: instead of winning a SpaceShipTwo ticket, the prize is now just a ride on a “vomit comet” style airplane.

In Orbit

In a quick flurry of launches, the Russian space program lofted 3 successful missions to end 2014 on a very positive note last week. The launches were all unmanned and unrelated to the ISS program. First, on December 23rd, the first flight of the new Angara rocket put a “dummy payload” into geosynchronous orbit.

Next, on December 26th, a Soyuz rocket put the Resurs P2 Earth observing satellite into orbit.

Lastly, on December 28th, a Proton rocket launched a European communication satellite to geosynchronous orbit. This was the 4th successful Proton launch since the failure in May. Proton is notorious for failures (one failure a year since 2010), and is intended to be replaced by the new Angara rocket.

Up on the ISS, the crew celebrated Christmas last week by putting out cookies for Santa Claus and exchanging presents. Astronaut Terry Virts shared their celebration with a few pictures on Twitter.

Out There

A new study with the Hubble Space Telescope has discovered a previously unknown “dwarf spheroidal” galaxy only 10 million light years from our galaxy. These types of small galaxies filled with older stars are expected to help astronomers improve models of star formation. The new galaxy is in our “Local Group” and is called KKs3. Hopefully someone at the IAU can come up with something more catchy.

Back in 2013, when Kepler’s second of four reaction wheels failed, it looked like the space telescopes science days were over. However, earlier this year the mission was relaunched as “K2″. The new mission uses the two remaining reaction wheels and solar wind pressure to keep the spacecraft pointed accurately enough to do science. The pointing is not as accurate as the original mission, but the first exoplanet discovery of the new mission proves that Kepler is not dead! Kepler found HIP 116454b, which is a small planet 2.5 Earth diameters in size.

With Christmas and New Year’s fast approaching (and Chanukah already here), everyone stays a little less connected, since more time is devoted to family and friends. So this week I have a rather short update on space news in the past week. I have plans for a pretty detailed “year in space” retrospective on 2014, which I will write after the holidays. So read this right quick and get back to the post office to ship those late gifts!

Down to Earth

SpaceX did not manage to get their CRS-5 (or 5th ISS resupply flight) off the ground as planned this week. They had an issue with their first attempt at the “static fire test” of the rocket on the pad and had to try again on Friday, December 19. The Friday test went well and launch is now no earlier than January 6th with rendezvous two days later.

In other SpaceX news, the company was awarded an $87 million contract with NASA to launch the Transiting Exoplanet Survey Satellite (TESS) on one of their Falcon 9 rockets in 2017.

The Commercial Cargo Resupply contract, which SpaceX and Orbital Sciences currently hold, will be coming up for rebid (for launches starting in 2018). Boeing is now on record that they plan to bid on the contract with their CST-100 vehicle, which, just this year, received an award for NASA’s commercial crew transfer contract.

In Orbit

In a little talked about test flight, India had a successful launch of its new GSLV Mark III rocket, which was carrying a rudimentary test article for a future crew module. Although I put this news in the “In Orbit” section, since it went to space, the mission was actually just a quick sub-orbital hop to 126 km. It’s an impressive step for India, but clearly there is a lot of work between here and a manned program.

Things are pretty quiet on the ISS, with the slip of the SpaceX mission to next month and the Christmas and New Year’s holidays coming up. With no Dragon to capture this weekend and a day or two off for Christmas next week, I imagine the astronauts will be taking lots of great photos of the Earth, as they always do. You should keep following Terry and Sam especially. Their Earth photography is always fun to look at and posted in near real-time, like this incredible shot of Cyprus in the Mediterranean.
