Down to Earth
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)
The Keck Telescope in Hawaii (where my dad works) was used for some new research into the Big Bang. The giant telescope looked at stars to get spectroscopic data of their Lithium isotope content in order to confirm a prediction made by The Big Bang Theory of the universe’s origin.
Because it’s cool
Perhaps the answer to Life the Universe and Everything is 3, not 42.
Down to Earth
Virgin Galactic has hired two new pilots, including former Space Shuttle Commander and Navy TOPGUN pilot, Frederick “CJ” Sturckow. Awesome!
At the Kennedy Space Center’s new visitor center, the payload bay doors were opened on Space Shuttle Atlantis, which is slated to go on display this summer.
In honor of the new Star Trek movie, here’s something that has nothing to do with space at all. But it’s funny.
A lot has happened at the space station in the past week and a half! Apart from Soyuz TMA-07M returning to Earth on Monday, May 13…
…on Thursday, May 9, in the morning, (while I was working in the Flight Control Room) the astronauts noticed some mysterious debris floating outside the space station…
…which led to an emergency spacewalk to fix a leaky coolant pump only two days later.
For more information, check out my friend and colleague, Anthony, talking about the space station quick fix.
Chris Hadfield’s return to Earth marks the end of a very successful mission that was more than just a typical ISS expedition. Commander Hadfield reached out to people through social media more than any astronaut before. Here is a small “greatest hits” list of some of his photography. But for me, even better than all the pictures from his mission, was the way Hadfield seamlessly connected his love of music to space. Check out this music video he released just hours before coming home last week.
In less successful orbital news, the Kepler Space Telescope – NASA’s planet-finding spacecraft – seems to be in trouble. On May 15, NASA announced that a second of Kepler’s four reaction wheels may be failed. Kepler needs 3 reaction wheels to accurately point the telescope for precision science measurements. If they cannot recover the lost reaction wheel, Kepler’s mission is effectively done. Kepler has been able to discover thousands of planets in our galaxy (most still being officially “confirmed”) but it easily has thousands more left to discover. Save Kepler!
Around the Solar System
In only one day last week, the sun emitted three X-class solar flares (X-class is the biggest class of solar flare, but just like the earthquake scale, an X10 is significantly bigger than an X2, so it’s all relative). Welcome to solar maximum! If you live somewhere where you can see it, there should be some good aurora to see this year.
Remember that rover on Mars? No, not the bigger shiny new one, that one on the other side of the planet – Opportunity. The plucky rover that could just hit a distance record for NASA set by the Apollo 17 moon rover in 1972. Back in 1972, Eugene Cernan and Harrison Schmidt drove their lunar rover 35.74 km in just a few days. After almost 10 years on Mars, Opportunity just broke that record this week. Also, there’s still the Russian moon rover Lunokhod 2 which drove 37 km in 1973. Opportunity still has a ways to go. But it is amazing that she is still going at all!
Down to Earth
I wrote last week about a few updates to Space Shuttle artifact exhibits coming online around the country. And there is yet more news to tell this week.
The exhibit of the Space Shuttle (not) Orbiter Enterprise at the Intrepid Sea, Air, and Space Museum is coming together after recovering from hurricane Sandy. The new upgraded “pavilion” is being built over Enterprise now and will open on July 10.
The last pieces of wrapping paper were taken off of Space Shuttle Atlantis at KSC.
The first Canadarm, or Space Shuttle robotic arm, was put on display at the Canada Aviation and Space Museum last week. ISS Commander Chris Hadfield was linked to the museum live from space for the unveiling.
Speaking of the Canadian Space Agency, Canada also revealed this past week that the new Canadian $5 bill will feature space images, including a picture of the Space Station Robitc arm and an astronaut on a spacewalk.
NASA resigned the contract with the Russian space agency to provide transport for American astronauts to ISS on Soyuz launch vehicles. The renewal paid for seats through 2017 – which is only 3 years before the official end of ISS in 2020 (but everyone expects the program to extend into the late 2020s).
Boeing successfully completed a flight test of the X-51A scramjet known as “Waverider”. This was the longest airbreathing scramjet flight to date (that’s unclassified…).
Not Quite in Orbit
As I wrote about in a separate post, Virgin Galactic had their first powered flight of SpaceShipTwo last week on April 29. The video is too good not to repost.
In the wake of all the excitement surrounding that flight, Virgin Galactic has confirmed that ticket prices are about to go up 25% from $200,000 to $250,000 to account for inflation.
The European Space Agency’s Herschel Space Observatory ran out of helium coolant last week and officially ended its mission.
A 3-D printer will fly to the ISS next year. This is a good idea in how to test ways to make spacecraft more self-sufficient, which will be necessary if humanity ever takes true deep space missions.
Chris Hadfield explains in a little over a minute my job as an Attitude Determination and Control Officer for ISS. Thanks, Chris!
The Fermi Gamma Ray Space Telescope did a debris avoidance maneuver in early April to avoid a nasty collision with an old Soviet Satellite. This was apparently the first time in Fermi’s mission (launched in 2008) that they had to use the thruster system for such a maneuver. This is a common problem for low Earth orbit spacecraft and the ISS has close calls with debris – and performs maneuvers – more than we would like to.
Around the Solar System
I enjoyed this story of unexpected scientific discovery. The team searching the outer solar system for an object for New Horizons to visit after it reaches Pluto happened to discover a new Trojan asteroid of Neptune (he explains what a Trojan asteroid is).
The Mars probes and rovers have woken up from solar conjunction. Opportunity and Curiosity should be off and roving again. Opportunity actually had a minor glitch when NASA initially resumed contact but she recovered no problem.
Down to Earth
A couple of updates on Space Shuttle artifacts being displayed. First, the original external fuel tank test article was shipped from KSC to the “Wings of Dreams Aviation Museum” in Starke, Florida. Second, the space shuttle Atlantis was “unwrapped” at its new display at the KSC visitor center.
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.
Down to Earth
Earlier this month, the White House released their proposed federal budget for fiscal year 2014. Which includes an allocation of $17.7 billion for NASA. Much has been said about the budget already – but the focuses seem to be on the $200 million cut from planetary science and the proposal to start planning an asteroid retrieval mission. Yes, you read that right, the idea is that NASA will send a robotic mission to find a worthy asteroid to drag back to cislunar space (that’s fancy space talk for bringing it as close to Earth as the moon). This may be the direction, focus, and “mission” that many have been saying was lacking from NASA’s portfolio since the cancellation of Constellation and the Space Shuttle. It is far too early to know what will come of it, at least until the mission starts being paid for in 2014. Personally, I think the idea makes sense and is exciting… more thoughts on this in a later post.
In truly down to Earth news, the ambitious Thirty Meter Telescope project received a permit to begin construction atop Mauna Kea in Hawaii. They project plans to begin construction in early 2014. the Thirty Meter Telescope (or TMT) will have almost 10 times the light gathering area of the Keck telescopes, also on Mauna Kea. TMT is going to be an amazing tool for astronomers. It should be able to look “further back in time” and see aspects of the beginning of the universe as well as be an awesome exoplanet finding tool, among many other science applications.
The Navy has announced they will be naming a new research vessel after Sally Ride (first American woman in space).
Virgin Galactic has been busy doing glide flights of SpaceShipTwo, getting ready for their first powered flight this year. In their most recent flight last week, the engine had a “cold flow” test – they flowed some propellant through the engine but did not ignite it.
Boston.com’s “The Big Picture” blog has a nice photo essay of two different Mars analog missions going on here on Earth.
After a planned launch this past Tuesday was delayed, today Orbital Sciences is going to attempt the maiden flight of the Antares rocket, which is planned to take the Cygnus freighter on resupply flights to the ISS. The launch is planned for 5 PM Eastern today (Saturday, April 20). If you read this in time, you can follow along at Spaceflight Now’s mission status center.
Around the Solar System
The Mars rover Curiosity went into hibernation starting on April 4 for the “solar conjunction”. This is the period when Mars is behind the sun as seen from Earth, making it difficult to communicate with probes at the red planet.
The Lunar Reconnaissance Orbiter was able to spot the fresh craters left by the GRAIL missions two probes that crashed into the moon last year (on purpose).
Some Mars enthusiasts from Russia have been scouring Mars Reconnaissance Orbiter images to look for the lost Mars 3 lander that the USSR sent to Mars in 1971. They seem to have found it!
NASA has announced two new missions in the agencies Astrophysics Explorer Program. Two space telescopes, TESS and NICER, are being developed for launch later this decade. TESS (Transiting Exoplanet Survey Sattelite) is somewhat of a successor to Kepler, and will be an Earth-orbiting satellite that hunts for exoplanets. NICER (Neutron Star Interior Composition Explorer) will be attached to the International Space Station and will look at x-ray wavelengths from neutron stars.
As I wrote about in my last post a week ago, ISS ops have been very busy lately. We were able to unberth and release the SpaceX Dragon capsule last Tuesday morning, as planned. It splashed down a few orbits later in the Pacific, while I was asleep, and was successfully picked up by SpaceX’s contracted recovery ship. I only got a bit of a rest after the Tuesday morning night shift as I had to work the day shift back in the control room Wednesday through Friday. More on what I got to do and see those days in the “In Orbit” section below. Anyway, that’s my excuse for the delay in posts lately. But you don’t really care – on with the space news!
Down to Earth
In a bit of grim space politics news – unless you are all about commercial only, I suppose – last week NASA’s 2013 budget finally became clear after the US Congress passed a big spending bill. The bill is better than the continuing resolutions* that a lot of the US government has been dealing with for a while – but it does nothing about the “sequestration” cuts across all Federal departments. This means that NASA ends up with greater than a 7% cut on the 2011 and 2012 funding levels. Ouch.
*A continuing resolution is simply an agreement to fund agencies or programs at the previous years levels because no agreement can be made on a new budget.
Masten Space Systems’ Xombie vertical-take-off-and-landing vehicle recently made its longest and highest flight to date, soaring over 500 meters according to their press release (no video yet available that I can find). Masten is using a guidance system developed by Draper Labs (of MIT) in order to build a testbed type craft on which NASA or other customer’s can test planetary landing instruments “without leaving home”, so to speak. I wrote about a similar test of the Xombie systems over a year ago, so this project has been in development for a while. This flight was ten times higher than the test last year.
The Aerospace Industries Association (AIA) has started a crowdfunding project at IndieGoGo to try to pay for NASA’s video “We Are the Explorers” to be run in American theaters before the movie Star Trek Into Darkness this spring (no, I don’t want to discuss if I capitalized that title correctly).
This is a clever, and apparently legal, way to get around the advertising ban that NASA is under. I donated!
Speaking of space cinema, a new IMAX movie was announced that will feature Earth photography from space. The film is being co-produced by Disney, and no release date or title has been announced.
Jeff Bezos, CEO of Amazon.com – who seems to be trying to compete – sponsored an expedition that has raised an F-1 rocket engine straight off the sea floor in the Atlantic. They do not know for sure which rocket the engine(s) came from, but they do intend to restore and display them. It seems they would likely be displayed at the Smithsonian; partly because the engines are still technically NASA’s property.
After Dragon left, the biggest event aboard ISS in the past two weeks was the docking of Soyuz 34 (or 34S to us) last Thursday only 5 hours and 45 minutes after launch. This was a new quick rendezvous profile that had previously only been used on flights of the unmanned Progress resupply spacecraft.
The Soyuz brought two cosmonauts – Pavel Vinogradov and Alexander Misurkin – and NASA astronaut Chris Cassidy. The speed of the launch-to-docking timeline was impressive even to those of us tied into ISS operations. As I was on the day shift Thursday, I had the privilege of giving a “Go” for launch at the end of my shift – and the colleague who I handed over to started prepping ISS systems for Soyuz arrival right after I left! I heard that the Soyuz reached ISS before the NASA personnel who were in Kazakhstan for the launch made it back to Moscow…
Amazingly, ISS Commander Chris Hadfield got this shot of Baikonaur at the moment of Soyuz ignition (by the laws of orbital mechanics, ISS often passes right over the location of launch for many ISS supply missions).
Speaking of which, if you haven’t been following ISS Commander Chris Hadfield (@cmdr_hadfield) on Twitter, you are seriously missing out on some stunning high resolution Earth photography posted nearly in real-time.
Also, the epic timelapse photography from the ISS Cupola… (via APOD).
Or if you want the more practical, here’s how to brush your teeth (I wasn’t originally going to share this until I heard the music kick in halfway through and started laughing).
Around the Solar System
Comet C/2012 F6 Lemmon (or just Lemmon for short) is set to start being a target for skywatchers this week (depending on your latitude). From the finder charts, it looks like Lemmon will still be too close to the sun at sunrise for most observers to have a chance at. Later in the month, Lemmon will move higher in the sky at dawn and may turn out to be as bright or better than Comet PanSTARRS which some of us enjoyed last month. Of course, the catch is that Lemmon will be a morning object rather than an evening object, so is likely to attract fewer hunters. You can bet I will try to see it!
The European Space Agency and Roscosmos (of Russia) formally signed an agreement last month to move forward with their Exomars mission, which will consist of orbiters and a rover to be flown to Mars later this decade. This is the big mission that NASA had to pull out of due to budget reasons.
New research using the Keck Telescopes in Hawaii has revealed compelling evidence for the nature and composition of undersea ocean’s on Jupiter’s moon Europa. Read a great summary of the research at Phil Plait’s blog.
It has been a while since I have posted one of my weekly space news links posts. Part of the reason has been a whirlwind move that we (my girlfriend and I) made from our apartment into a new house. We currently don’t have internet, which hampers my blogging a bit. But also, I have been busy at work, including having the privilege of working rather closely on the current SpaceX mission to ISS, which has been exciting. I even attended a joint planning meeting for the mission today to talk about unberth and departure of the Dragon capsule on March 25th, which I will get to support from the Mission Control Center.
Down to Earth
It’s official. As of late last month, the US House of Representatives finally passed a bill to rename the Dryden Flight Research Center in California the Neil A. Armstrong Flight Research Center. The proposal still needs to be approved by the Senate.
An international research team working in Antarctica has found an 18 kg meteorite on the ice surface of that barren continent. This is the largest meteorite find in Antarctica since 1988.
Millionaire and former space tourist, Dennis Tito, announced last month that he intends to create a new space “adventure” (not venture) known as Inspiration Mars. The intent of the project is to send humans (ostensibly a single married couple) on a circum-Martian flight that would take about 500 days. The mission would not involve a landing on the planet, due to cost and complexity, but would seek to inspire a generation and possibly lead to greater adventures (and ventures) in the future. Color me skeptical, but I hope they can do it! Fundraising will be a challenge.
Here are some helpful ideas of how Inspiration Mars might be able to generate revenue to make their mission a success.
SpaceX did another hover test of their huge Grasshopper vertical landing test rocket. Cool stuff.
On March 1, SpaceX successfully launched another Dragon cargo craft to ISS on the first attempt.
SpaceX had some issues with their propellant system that delayed their spacecraft’s arrival at ISS by a day. Dragon arrived with no problems on Sunday, March 3, after many meetings to discuss the issues and agree to a replan. I was working in the Houston Mission control Center that weekend and was impressed to see the machine of mission operations chugging away to produce such a quick turnaround of the timeline!
I enjoyed watching the ISS crew open the Dragon hatch and begin unloading on Sunday evening, which I already wrote about in a previous post.
Around the Solar System
On Mars, the Curiosity rover is having some unknown computer memory issues. On February 28th, ground controllers intentionally commanded the rover to use the backup computer, which put the rover into safe mode (coincidentally, on the same day that SpaceX’s Dragon capsule was having issues). The rover is currently functioning while teams back on Earth prepare to send software “patches” to the rover later this week.
NASA’s Van Allen Probe mission has discovered a third distinct radiation belt around Earth.
This week, the comet panSTARRS is making an appearance in the Northern hemisphere’s skies. This is one of the two comets (the other being comet Lemmon) that were supposed to make a splash this year. PanSTARRS has not turned out to be dimmer than hoped, but still worth looking for. The comet just passed the sun and is coming around the other side, which is why it is fading out of peak brightness while also creeping higher above the horizon after sunset. I was able to find panSTARRS with my binoculars this evening and she is definitely pretty, if small.
Speaking of comets, a newly discovered comet, named Siding Spring, is predicted to have a very close approach of Mars (not us, phew!) in late 2014. The uncertainty in the orbit leaves the possibility open that the comet make actually impact Mars. This would be a bad day for Mars and our spacecraft stationed there. Phil Plait explores the possibility of destruction, while Emily Lakdawalla considers the more benign possibility of a nice meteor shower.
Wow, it’s been a busy week and a half! Ten days is the longest I’ve gone without posting some links since I started my blog over a year ago. Not only has space news been busy, with asteroids galore, but I have been busy too, with a weekend getaway last weekend and then 3 nights of ISS mission ops this week. Hopefully the news I share below will get us all back up to speed!
Down to Earth
The first thing I have to talk about is the asteroid impact in the Chelyabinsk area of Russia in the Ural mountains. The short story is that just hours before the much anticipated fly-by of large asteroid 2012 DA14 last Friday, February 15, an asteroid about 15 meters across entered the Earth’s atmosphere above Russia and exploded without warning over a relatively large city in Russia. The airburst was the equivalent of may kilotons of TNT and it managed to cause widespread injury and property damage (no reports of deaths that I am aware of).
Here is a pretty good video of the meteor.
And this one has the sound of the meteor exploding. Scary.
Experts are sure, based on tracing the Chelyabinsk meteor’s orbit back the way it came, that 2012 DA14 and Chelyabinsk are unrelated. It is what you might call a “cosmic coincidince”. Phil Plait talks about the chances of such a coincidence and also the sober reality that we need to take asteroid threats more seriously.
The more interesting coincidence to me is that asteroid impacts of this size are only expected to happen about once a century. The last large impact (that is known) happened in 1908, also in Russia.
Maybe not surprisingly, a weather satellite got some brief images of the smoke trail from the Chelyabinsk meteor. I don’t want to leave poor 2012 DA14 out to dry, so here’s a timelapse of its flyby of Earth.
In some non-asteroid news, the new Space Shuttle display at KSC in Florida is officially opening on June 29. This date was announced at an unveiling of the facility’s new logo.
The test firing of Orbital Science’s Antares rocket was completed successfully earlier this evening. This is good news for their program, which needs to catch up with SpaceX. SpaceX is getting ready for their third cargo flight to ISS next week.
The mayor of Brownsville, Texas met with Elon Musk of SpaceX last week to discuss further the possibility of SpaceX building their next launch site on Boca Chica Beach in South Texas.
NASA astronauts aboard ISS had their first public Google+ hangout. Cool!
There was a bit of excitement in ISS mission ops earlier this week when the first day of ISS computer software upgrades did not go as planned. A computer restart did not execute properly and it resulted in a temporary loss of communications between ISS and mission control. You may have heard about it, since it was all over the news when it happened on Tuesday. Fortunately, flight controllers, with the help of the crew, were able to resolve the problem and the software upgrades were completed. All is well in space!
Around the Solar System
Mercury had its longest “Eastern elongation” last week – meaning it was at its highest point above the horizon at sunset, as seen from Eearth.
The new company “Inspiration Mars Foundation” – founded by space tourist Dennis Tito – claims to be planning a 500 day Mars trip to be launched in 2018. I wish them luck.
This week it was announced that the smallest exoplanet ever discovered was found 200 light years away. The planet is Kepler-37b (meaning it was found by the Kepler mission) and is only 2,400 miles in diameter, which makes it smaller than Mercury. As usual, the planet is far too close to its parent star to be habitable in any way.
Down to Earth
The bad winter weather hasn’t been a problem down here in Texas, of course – but we’re all thinking of our friends in the Northeast that are snowed in. Here’s a NASA satellite timelapse of the blizzard that has been affecting the East coast.
Tomorrow night, Orbital Sciences Corporation will be doing a “hot fire test” on their launch pad in Virginia. the test is in preparation for their first test flight to ISS later this year.
Listen to this duet between Ed Robertson of the Barenaked Ladies and ISS astronaut Chris Hadfield… recorded during Hadfield’s current stay in orbit.
Here is a video of Chris Hadfield’s live discussion with William Shatner last week.
In ISS ops, it has been a busy few days. early Friday morning the ISS did a long maneuver (with myself happily monitoring from the ground!) from facing forward to facing directly backwards to prep for the Progress 48 cargo craft to undock early Saturday morning, which happened as planned (unless you are a huge geek the video below is pretty boring).
Then ISS stayed in that backwards attitude over the weekend awaiting the new Progress 50 cargo craft, which launched earlier today and just docked to ISS at just before 4 PM Eastern.
Since those docking ops are complete, the ISS will be maneuvered back to the normal flight attitude on the night shift tonight (early Tuesday morning). Once again, I have the privileged responsibility of being the guidance and control officer for the maneuver. This will be about the 4th major activity I have worked in the front flight control room for since my most recent certification last year. Very exciting!
There were actually two launches today. In addition to the Progress supply vehicle, NASA launched the LDCM out of Vandenberg in California. LDCM is an Earth observation mission.

Curiosity has done its first drilling on Mars.
There is open public voting at plutorocks.com to name the 4th and 5th moons in the busy Pluto system. Voting is only for the next two weeks. You can write-in suggestions if you do not like the list of names they already have.

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.
