Down to Earth
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.
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.
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.
Because it’s Cool
XKCD takes a new tact on an old saying about space and perseverance.
Retired ISS Commander Chris Hadfield is now charging full into his book tour to promote his memoir-slash-self-help book An Astronaut’s Guide to Life on Earth. I have been thoroughly enjoying his short videos promoting himself and his book. I think he is fitting into his post-space career very well. Check it out.
Down to Earth
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.
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.
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.
Down to Earth
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.
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.

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.

One of the three original founders of the Planetary Society, Bruce Murray, passed away on August 29th. Murray was director of NASA’s Jet Propulsion Laboratory during the Viking and Voyager era. He started The Planetary Society with Lou Friedman and Carl Sagan in 1980. If you are a space enthusiast and you are not yet a member of the Planetary Society, you are missing out. Check out their website and weekly radio show.
Last week three ISS crew members returned to Earth, ending Expedition 36. Chris Cassidy, Pavel Vinogradov, and Alexander Misurkin landed on September 11 in Kazakhstan. Next week a new crew will launch and dock on Wednesday, September 26.
Not Quite in Orbit
It seems cosmonaut Yuri Lonchakov – who was in space on Expedition 18 when I started working at JSC – has decided to retire from the space business. He had been in training to fly as commander of Expedition 44 in two years, which is what makes the departure somewhat confusing. However, as NASA Watch points out, he has been in the corps for a long time, with his first flight over a decade ago on STS-100. Everyone has to move on some time.
Last post I wrote about the second powered flight of SpaceShipTwo on September 5, and included some cool footage of the flight from the ground. Well, since then, Virgin Galactic released this view from onboard the spaceplane. Very cool (via Ubergizmo).
Last week on the 12th, SpaceX did a “static firing” (which means the rocket didn’t go anywhere) of the new Falcon 9 rocket on the pad at Vandenberg Air Force Base in California (here’s a Google Maps link). Unfortunately, they saw some anomalies and the test launch was delayed from the planned date of the 15th. According to Elon Musk, they hope to launch at the end of the month.There was a problem connecting to Twitter.
The new rocket is the Falcon 9 version 1.1. As you can see in the graphic below (from Wikipedia), version 1.1 is a significant visual upgrade from the existing Falcon 9. In addition to the payload faring and longer fuel tanks – making it taller – they are upgrading the Merlin engines that power the first stage. All future Falcon flights are supposed to transition to this rocket after the tests, including NASA cargo flights to ISS. So here’s hoping for a good launch in a week or two!
This morning at 10:50 AM Eastern, the Antares rocket carrying the first Cygnus cargo craft launched from Wallops Island, Virginia on the way to ISS.
The flight will bring Cygnus up to ISS for rendezvous this coming Sunday, September 22nd. My favorite part of the launch is this clever sign near the launch pad that made for a good photo op. Or maybe this bald eagle who had a front row seat is cooler?
As of this writing, the spacecraft has already done initial checkouts, with more ongoing.
In a nice double-whammy, there was also a big rocket launch from Florida early this morning. A United Launch Alliance Atlas V rocket launched an Air Force satellite before dawn at Cape Canaveral.
I was intrigued by this article at the Huffington Post about NASA’s radiation limits on active astronauts. Because of differing risks for cancer between genders, women have lower allowed limits of radiation, meaning they can’t fly as many days in space.
Around the Solar System
In somber news, mission managers of the Deep Impact/EPOXI mission announced earlier this month that they have been out of contact with the spacecraft for about a month. Flight controllers have indications that the onboard computer had a glitch and is now likely spinning out of control, which is why they can’t get commands uplinked to correct the problem – the communications antenna is not pointing towards home. The worry is that if it spins out of control for too long, the batteries won’t get charged from the solar arrays and the spacecraft will die.
EPOXI was launched as Deep Impact in 2005 and has had a very successful mission so far, with the rendezvous and impact of comet Tempel 1 and then years later the dramatic flyby of comet Hartley 2.
The biggest space news so far this month, at least that the public has noticed, was the official announcement by NASA that the Voyager 1 spacecraft has entered interstellar space. Some people were incorrectly reporting the announcement as “Voyager 1 has left the solar system” which makes me roll my eyes (see below). Phil Plait of Bad Astronomy covers this topic well.
It’s been a whole month since I last posted, so there is some catching up to do. I’m going to try to just hit the highlights.
Down to Earth
A few quick news items from the “NewSpace” sector:
Most exciting and most recently, today Virgin Galactic flew the second powered flight of the SpaceShipTwo space plane. This test involved “feathering” the spaceship’s wings after the engine is shut down to help with a controlled “re-entry”. With this only being the second test flight of the year – the first was back in April – it seems unlikely Virgin will start flights to space by the end of the year. Still, it is awesome to see progress. Here’s a video of the flight.
ATK has partnered with Orbital Sciences to build the rocket for Stratolaunch. Orbital is designing the rocket and ATK will provide the first and second stages. For those that need a refresher, Stratolaunch is the Paul Allen project to have a 747-sized plane be the launch platform for a massive rocket that can deliver as much as 13,500 pounds to Earth orbit.
Last month Sierra Nevada’s “Dream Chaser” space plane went through some taxi tests out in California. Basically, it was just towed down the runway to test the landing gear. But if you think that’s exciting, there’s a video! Interestingly, the nose landing gear is a skid, not a wheel.
SpaceX had another test flight of their “Grasshopper” vertical take off and landing rocket. This time it was a “divert” test where it flew sideways and came back. Here’s the video.
In the NASA world there are a few updates also:
First of all, deputy NASA administrator Lori Garver has announced she will be leaving NASA for a job in the private sector (specifically as president of the American Airline Pilots Association).
Astronaut Mike Foale is also leaving NASA after a 26 year career.
A recent paper was published identifying 12 EROs (easily-retrievable objects) to add to a list of possible destinations for NASA’s asteroid retrieval mission. Unfortunately, Lori Garver (see above) was a chief proponent of this new controversial mission. Check out this article in the Washington Post outlining some of the technical and political issues that may hinder this mission.
Tomorrow night at 11:27 PM Eastern time, NASA’s LADEE (Lunar Atmosphere and Dust Environment Explorer) will launch from the Wallops Island facility in Virginia. The launch should be visible to much of the East coast, so stay up to watch if you can! The spacecraft will not have any cameras. Instead, it has spectrometers and dust scoops for studying the tenuous lunar atmosphere. Once LADEE has launched it will clear the Wallops Island launch range for the Orbital Sciences launch of their first Cygnus flight to ISS on September 17th.
A link I should have posted weeks ago is a first hand account from ESA astronaut Luca Parmitano of the EVA which was aborted in July when his helmet started filling up with water. This was probably the scariest thing to happen in spaceflight since the loss of Columbia a decade ago. Great job by flight controllers and especially Luca in staying calm under pressure.
NASA is officially no longer attempting to fully recover the Kepler Space Telescope. Fortunately, lots of people are thinking of ways Kepler can still do exciting science without the stability of three gyroscopes. One of the most publicized white papers from this past week was the idea to look for planets in the very close habitable zones of white dwarf stars.
Similarly, the WISE spacecraft (wide-field infrared survey explorer) is getting a new mission. WISE is being reactivated on a 3-year mission to look for NEOs (Near-Earth Object). As Phil Plait points out, this mission may be directly related to NASA’s asteroid retrieval mission, and the effort to find a candidate rock to go grab.
To round out the space telescope news, the Spitzer Space Telescope celebrated its 10th year in space this summer. Spitzer ran out of liquid helium coolant in 2009 but is still going strong with its “warm mission”.
In what is a startling development, the United States Air Force’s “Space Fence” will be shut down after the end of this fiscal year. The Space Fence is a key part of our orbital surveillance program. Without the space fence program there will be a gap in capability until if and when the new system comes on line in a few years. It’s very possible that without this system the risk of debris striking any given spacecraft without warning – including the ISS – goes up.

Speaking of Virgin Galactic, the term “space tourism” has been officially added to the OED.
The great XKCD comic recently did a great job describing the basics of orbital mechanics.
Somebody recreated the famous shot of a bike flying in front of the moon from the movie E.T.
In a post in July I wrote about how Hubble had determined the color of a far-flung exoplanet. What I failed to mention that they had also discovered that on this planet it probably “rains glass sideways”, which is a bit of a let down if you are wanting to visit this nifty blue world someday. The web comic Sci-Ence is apparently annoyed at how often the planets we discover are unlivable, and has created a handy guide.
Tomorrow morning I will be getting up at 4 AM to go in early for my day shift at ISS mission control. I am assigned to the regular day shift from 7 AM to 4 PM all week. It just so happens that the first shift is the same day as a Russian ISS spacewalk. Cosmonauts Fyodor Yurchikhin and Aleksandr Misurkin will perform the 33rd Russian spacewalk onboard ISS. You can read all about what they will be working on over at Spaceflight101.com.
While I will be working a long 11 hour shift starting early in the morning, I am definitely still looking forward to it. This will be my first time in the Flight Control Room for a spacewalk. I previously supported from the Multi-Purpose Support Room for US EVA 20 last fall, with a more experienced flight controller in the ADCO seat. Being assigned a shift as ADCO for an important event like a spacewalk is definitely a lot of responsibility to take on. But ADCO has relatively little to do for most spacewalks when compared to many other flight controllers and support personnel who have a direct responsibility to the safety of the crew and the tasks being performed. If my ADCO team does our job well tomorrow, we will actually do and say very little for all 11 hours we are there.
One important task we have is to send commands related to disabling the Russian Segment thrusters late in the EVA. There are some maintenance tasks that will take the cosmonauts close enough to the back end of the Russian Service Module that flight rules dictate all thruster valves closed for safety reasons. We will be monitoring the spacewalk progress closely to make sure we are ready for disabling thrusters as needed.
Other than that, it will be an exercise in listening and patience. I would say it is an exercise in bladder management also, but at least I am allowed to leave the room briefly for breaks during the spacewalk. The cosmonauts will have to go probably close to 8 hours without food and bathroom breaks. And that’s why I’m not complaining about my 4 AM alarm. Bring on the shift!

Sally Ride is to be posthumously awarded the Presidential Medal of Freedom.
Recently returned ISS Commander Chris Hadfield announced his retirement from the Canadian astronaut corps today.
Last month, the governor of Texas signed a new law that is necessary for SpaceX to build a new spaceport near South Padre Island and Brownsville. The bill allows the mandated closure of Boca Chica Beach – a public state park – on the days of rocket launches. This bill is a big step towards SpaceX making South Texas their second launch site.
Apparently Justin Bieber made a down payment on a spaceflight with Virgin Galactic last week.
If you are a night owl (or the opposite) you should go outside at about 4:30 AM (Eastern) on Tuesday, June 11, and see if you can spot some Gamma Delphinid meteors. The possible meteor outburst may only last 30 minutes or so, but may be dramatic.
The asteroid mining company Planetary Resources launched a “crowdfunding” campaign last month to help them raise money for their asteroid hunting space telescope(s). They are getting close to their $1 million goal. I think it is worth donating (I contributed already) just for the possibility of getting the cool “space selfie” perk they are offering. They are planning to have a small video screen on the outside of the spacecraft that can display photographs that can then be themselves photographed against the backdrop of the Earth.
Warner Brothers intends to make a feature film based on the nonfiction book “Spacesuit: Fashioning Apollo”. I’ll go see it!
On Wednesday, May 29, the second half of Expedition 36 docked to the ISS in the second “express” docking. Launch to docking time was about 6 hours. The new crew consists of Karen Nyberg (American), Luca Parmitano (Italian), and Fyodor Yurchikhin (Russian). Soyuz Commander Yurchikhin is on his third spaceflight. He was just in space exactly 3 years ago for Expedition 24.
Last week, the fourth European transfer vehicle (ATV4) launched from French Guiana on its way to ISS. ATV4 is named “Albert Einstein” and will stay docked to ISS for several months.
Early tomorrow morning, China intends to launch their fifth manned spaceflight. The mission will be Shenzhou 10, and will send three taikonauts to the Chinese Tiangong-1 space station. (via NASA Watch)

Rumor has it that Virgin Galactic might have their first powered test flight of SpaceShipTwo next week.
The Texas state legislature is a few steps away from approving key measures that would enable SpaceX to build a launch site near the Mexico border outside of Brownsville. This week the Texas House of Representatives approved a bill that would allow closure of state beaches during launches. The bill still needs to go to the State Senate before passing.
Mars One, the… company? … that plans to colonize Mars, has opened up their astronaut application process. What the heck, why not apply?
Orbital Sciences successfully launched their first Antares rocket on April 21st. It was a beautiful launch into a clear blue sky. We look forward to seeing them on ISS in a few months.
Up on the Space Station, two cosmonauts – Pavel Vinogradov and Roman Romanenko – went on a six-and-a-half hour spacewalk to work on some external experiments and also some various maintenance.
On Wednesday, the latest Russian Progress resupply craft launched on its way to ISS. The docking is planned for just a few moments from now, on Friday morning (coverage is live on NASA TV if you catch this post right after it goes up). The Progress will be docking to ISS despite a rendezvous antenna that was unable to fully deploy after launch. The retracted antenna is physically in the way of the docking mechanism, so flight controllers will have to come up with a plan to get the antenna out of the way… or something else. Otherwise the cargo inside will not be accessible. One possibility is to plan another spacewalk after docking to move the antenna.
And on a lighter note, Commander Hadfield talks about barf bags in space.
Around the Solar System
At Saturn, the Cassini spacecraft has been observing meteors impacting the planet’s rings. Awesome.
Last weekend, the six-man crew onboard the ISS got a special delivery from Earth. The third in what we hope will be a long line of SpaceX Dragon capsules was grabbed by the space station robot arm on Sunday morning. It didn’t take very long after the Dragon was firmly attached for the crew to start working diligently to get the hatches open and get to the cargo inside, even though it was supposed to be partly their day off.
Why the rush? Well if you had only eaten fresh food a few times in the last four months you would be excited too! About 2-4 cargo deliveries will happen during an astronaut’s stay on ISS – so that means you only get to enjoy fresh fruit and vegetables in your diet for a few weeks of your stay.
I was on shift in ISS mission control on Sunday when the crew got the hatch open and you bet they wanted to know where the bags of apples were stored away. Not only did they find the expected NASA manifested bag of apples, tomatoes, and other items, but SpaceX had hidden away a special care package of extra apples and oranges. Their excitement was clear and I’m sure they had a good dinner that night.
What I think comes to light in this case is the interesting economics of supplying a space station, or I suppose any remote operating base. An orange is cheap – your neighbor’s tree might drop some over the fence into your yard and they would never know they were missing nor probably care. But the cost of launching those oranges to ISS makes them worth a lot – not quite equivalent to gold by weight, but getting close. Imagine if the trip to the grocery store cost you 10,000 times more than the groceries themselves? That’s a cost of living that would make even San Franciscans cringe.
This is obviously one important reason that spaceflight is so expensive. By having companies like SpaceX to run supply missions, launch costs can be reduced through efficiency and frequency. But even so, launch costs can only drop by so much. Thus, we will never truly be a spacefaring species unless we learn to be self-sufficient. The European colonies in America only prospered when they learned to live off of the local resources. As long as oranges are worth $2,000, we will be stuck in low earth orbit like some colonists in a coastal fort waiting for the next ship from England.
Someday the lessons we are slowly learning about self-sufficiency on ISS and elsewhere (like bases in Antarctica) will take us outward – but until then I would hate to be the astronauts up there stuck with the guilt of eating a $2,000 orange. What does it feel like to know that so much effort went into getting you just a few bites of fruit?
Down to Earth
NASA administrator Charles Bolden and Buzz Aldrin laying a wreath at Arlington.
You thought it was all over last month didn’t you? Well think again. The deal that the 112th Congress agreed to early in January only delayed the “sequestration” of the federal budget. Sequestration is a returning threat if a more permanent deal can’t be reached by March. This will of course have far-reaching impacts in this country, including in space exploration. Here’s a summary from the Planetary Society about what sequestration would mean for NASA’s planetary science programs. The bottom line though is that NASA leadership has not publicly indicated how drastic budget cuts would be dolled out within the administration.
Ron McNair died in the 1986 Space Shuttle Challenger disaster. His brother remembers him in a story that was turned into this cartoon by StoryCorps.
Later this morning – at 10:30 AM eastern – famed actor William Shatner will have a public video conference with ISS astronaut Chris Hadfield. As I understand it, some of America’s major news networks plan to cover the brief event.
The large asteroid 2012 DA14 will fly within just 17,200 miles of the Earth next week, on the 15th. That distance is below the roughly 22,400 mile altitude of geosynchronous orbit. The asteroid is about 50 meters or so across so it will be too small to see with the naked eye. I have not read anything that indicates we should be worried about a gravitational “keyhole” for 2012 DA14. It does not seem to be at a high risk for impact in the near future.
In less serious asteroid news, there is one out there with the newly minted official name “Wikipedia”.
There was some speculation earlier this week that the Iranian space monkey launch was faked. The accusation was based on the before and after pictures of the monkey, which appeared to be of a different animal, to experts. Iran has said they simply used the wrong photos, but they did really send their monkey on a successful suborbital flight.
Bigelow Aerospace has posted pricing information for trips to their planned Earth orbit space station. Visitors would fly up on SpaceX’s Dragon capsule or Boeing’s CST-100. The flights are noticeably cheaper than what tourists have paid in the past to travel to ISS. This is all well and good, but I want to know why Bigelow is calling their station “Alpha Station” when some NASA astronauts still refer to ISS as “Space Station Alpha”. Could get confusing.

Mercury and Mars are having a very close conjunction in the sky (as seen from Earth). At dusk today, February 7th, you should look West if you have a clear view to the horizon, and you may be lucky enough to spot this unlikely pair. You probably need binoculars to easily see the planets.
