Down to Earth

Unfortunately, putting Sally Ride in the US Capitol Statuary Hall is on hold. The issue is that Father Junipero Serra’s statue would be removed and he is expected to be canonized soon. The bill was on the docket in the California state legislature (I linked to the original proposal back in April).

Johann-Dietrich Woerner, as of July 1, is the new the ESA Director General. Previously, he was the head of the German space agency.

My favorite news of the week, other than all the goings-on with the ISS below, is that Houston’s Ellington field has been granted a Launch Site License by the FAA. This means it could be a “spaceport” in the future. It would be pretty cool to see takeoffs and landings of space vehicles from just down the road here!

In Orbit

As of June 29th, Gennady Padalka, current commander of Expedition 44 onboard ISS, became the most-flown astronaut or cosmonaut. The previous record of 803 cumulative days in space, held by Sergei Krikalev ,was broken by Padalka on Tuesday. He will get to almost 900 days before he comes home in September. Krikalev’s flew in space six times, while this is Padalka’s fifth.

Of course, the biggest news of the week was the loss of SpaceX’s Falcon 9 rocket on June 28th. The rocket was launched to send another Dragon capsule to the ISS for their 7th resupply flight (8th if you count the demo mission). The rocket came apart just a couple of minutes into the flight. Here’s the video:

SpaceX will of course have to do an investigation of the failure, and possibly make some design changes, before their next flight. Some important but not critical ISS cargo was lost on the mission, like a new docking adapter and spacesuit parts. There’s a good cargo list on Wikipedia, or check out this post from Parabolic Arc.

Fortunately, given that the ISS has many partners, including four redundant rockets used for resupply, the loss of one SpaceX mission hopefully won’t pose a longterm problem for the program. Just last night, Russia launched a Progress resupply spacecraft, which will dock to ISS tomorrow. The Progress brings all kinds of cargo, including propellant, food, water, and other supplies.

It is interesting to look at some numbers with SpaceX. The launch failure was their first with the Falcon 9 rocket, which had previously had 18 successful flights. Also, before the failure, they had launched five Falcon 9 flights successfully in 2015. Their previous record flight rate was 6 flights in 2014. They could still fly more this year depending on how the failure investigation goes. Parabolic Arc has a nice breakdown of what their upcoming manifest looked like before the failure.

As usual, ISS commander Scott Kelly posted some great photos of Earth from space over the last week:

Update from comet 67PP/Churyumov-Gerasimenko: mission controllers are still trying to establish consistent contact with the Philae lander. Meanwhile, the Rosetta orbiter is doing awesome science, like discovering lots of surface ice and sinkholes (I think I’d rather call them “air pockets”).

Check out the obvious red color (probably caused by hydrocarbons, not rust) in recent images of Pluto from New Horizons. Only 2 weeks until rendezvous, and NASA has given the all-clear for the close encounter on the current orbit. No new hazards (moons or rings) have been spotted in Pluto orbit.

A new exhibit called ‘Forever Remembered’ at NASA’s Kennedy Space Center has opened, featuring artifacts from the fateful STS-51L and STS-107 missions.

NASA is offering to lease parts of the Vehicle Assembly Building (VAB) and Mobile Launch Platforms (MLP) at the Kennedy Space Center to commercial users. I guess NASA doesn’t need both high bays all the time due to the low launch rate expected for the new SLS rocket.

Famous composer James Horner died in a plane crash this week. Here are some excerpts from my favorite work of his, the Apollo 13 soundtrack:

In Orbit

In orbital launch news, the Russian military launch I wrote about last week was successful on June 23rd. The rocket was a Soyuz-2.1b, which has a different third stage than the Soyuz rockets used to launch missions to ISS. Here is a good discussion of the Soyuz rocket family from Russian Space Web.

There was also a Chinese Earth-observing satellite launch on June 26 (was early in the day, so June 25 in the US).

And of course, another much-anticipated SpaceX Falcon 9 launch is still scheduled for tomorrow. The pre-launch static fire test was successful on Friday, June 26, so they are ready for launch on June 27 at around 10:20 AM Eastern.

This Falcon 9 launch is supposed to have another barge landing attempt. SpaceX recently launched this new tracking cam footage of the almost-made-it attempt in April. This should get you excited for tomorrow!

As always, here are some more great photos from ISS, posted by @StationCDRKelly

Around the Solar System

The European Space Agency has extended the Rosetta mission, in orbit of comet 67P, until late 2016. Good thing too, because Rosetta keeps finding new things about comet 67P, like the recent announcement that they have found exposed water ice on the surface.

This song about the New Horizons mission to Pluto is rather fun. If you don’t like sentimentality or kitsch, you might want to skip it.

Some cool astronomy news worth sharing this week. First, the V404 Cygni system, which is a black hole orbited by a companion star, has recently become very active and is flaring into the brightest X-ray object in the sky (so you can’t see it).

Second, astronomers have discovered that exoplanet GJ436b (which is about the size of Neptune) has a giant cloud of hydrogen following it in its orbit, like a comet tail.

For the rocket junkies, the first launch since June 5th occurred today. The ESA Earth-observing satellite Sentinel-2 launched from French Guiana just a little while ago as I write this. There are no press releases up about the successful launch yet, so here is the Wikipedia page about the mission. Russia is launching a reconnaissance mission on a Soyuz rocket tomorrow, and then there is the SpaceX launch next Monday (see Wikipedia page 2015 in spaceflight for launch schedule).

On Thursday, ISS flight control teams commanded a reboost burn in order to slightly changing the station’s orbit. This is done to make sure that upcoming rendezvous events, like the next Soyuz launch and docking in July, happen when and where they are planned.

Robonaut 2, which lives aboard the ISS, was named the 2014 Government Invention of the Year (US).

New high definition videos of cities, filmed from the ISS, were released by UrtheCast. From 200+ miles up, you can see cars moving on streets and boats on rivers. More than that though, I think I like watching the buildings “move” as the perspective shifts at 17,500 mph.

The Planetary Society’s LightSail solar sailing test re-entered Earth’s atmosphere last Sunday, June 13th. Their next test launch will be late in 2016.

Roscosmos has announced that Sarah Brightman’s empty seat on Soyuz TMA-18M later this year will be filled by a cosmonaut from Kazakhstan.

Scott Kelly is doing a great job still posting a great variety of beautiful images from ISS on Twitter all by himself. Here is a sampling:

ESA’s Philae lander, which has been hibernating on comet 67P since November, has woken up! Data was received by the Rosetta orbiter on June 13 and 14, prompting the mission team to start making plans for when they gain a more solid link with the probe.

Scientists have discovered methane in Martian meteorites (pieces of Mars that came to Earth as a meteorite), thus confirming and deepening the mystery around the methane that has been detected at Mars by various spacecraft.

SpaceX officially received certification from the United States Air Force (USAF) to launch military payloads.

NASA has officially ordered the first official crew rotation flight to ISS under the contracts awarded to Boeing and SpaceX last year. Boeing is expected to make this flight (after a demo flight) in late 2017.

At NASA’s Stennis Space Center, the new RS-25 rocket engine went through a long duration test firing. The RS-25 is a modified space shuttle main engine and will be used on NASA’s new SLS rocket. Here is the full video of the 450 second (7.5 minute) test:

A new venture called MarsPolar hopes to work with SpaceX to mount the first expeditions to Mars. They have a rather shiny website (and an awesome logo). There are a lot of ambitious people promising big dreams these days, which is exciting. But it is hard to take these announcements seriously until we start seeing results. I wish them luck!

In Orbit

The big event on ISS last week was the relocation of the Permanent Multipurpose Module (PMM) from the bottom of ISS to another out of the way port, so that the previous location can be used as a docking port. Here are some images and timelapses of the operation:

The ISS is currently in perpetual twilight during a time of year we call “high beta”. This often means frequent and very bright ISS passes for much of the world. My favorite way to look up whether ISS will be flying over my location is with the website Heavens Above.

In rocket news, only one orbital rocket launched in the past week: an Ariane 5 rocket carrying a DirecTV satellite. The next ISS related launches are expected to be a SpaceX launch late in June and hopefully also the next Progress launch.

Around the solar System

As New Horizons is now less than two months from closest approach to Pluto, we are getting higher resolution images of the dwarf planet every week. Here is the latest batch. Here’s an animation of the imagery (via APOD):

These images are more than just pretty pictures. The New Horizons mission control team is watching Pluto and its moons closely throughout approach to ensure no hazards will destroy the spacecraft at the close encounter. Analysis so far is good.

If you are excited about the Pluto mission, maybe you should download the new “Pluto Safari” iPhone app. I have downloaded it, but not played with it yet.

Another SpaceX Dragon capsule completed its mission with a splashdown in the Pacific on Thursday, May 21st. Their next ISS mission is scheduled for late June.

NASA has certified SpaceX’s Falcon 9 rocket to launch “medium risk” science missions.

Speaking of SpaceX, it looks like I forgot to post videos from their successful pad abort test earlier in May. Here is the original video as well as a new video from onboard the capsule, which is a must watch!

Congress has been doing a lot of space and NASA related work in their current session. The House Appropriations Committee has a markup that includes some details for NASA. Parabolic Arc has the breakdown.

In Orbit

There were two launches in the past two weeks, one successful and one not so successful. First, on May 16th, a Russian Proton rocket launched from Baikonaur with a Mexican commercial satellite did not deliver the payload to orbit. The last time a Proton rocket failed was about a year ago. They had had 6 successful launches between these most recent two failures.

The good news is that on Wednesday, May 20th, a United Launch Alliance Atlas 5 launched from Florida on a flawless flight that delivered the Air Force’s secret X-37B spaceplane and also a fleet of ride-along cubesats.

Among the cubesats on the launch was the awesome LightSail mission from the Planetary Society. The citizen-funded mission is a technology demonstration mission of solar sailing. The current mission is to demonstrate that the sail can be unfolded in orbit. A later mission in 2016 will actually go to a high enough orbit to use light from the sun to steer. You can follow the mission here and contribute to their funding here.

On May 15th, a glitch on the space station caused a reboost, or orbital trajectory correction burn, to be cancelled. Mission controllers were able to turn the plan around and get a good reboost a couple of days later though. Way to go team! (I was on vacation in Austin, so I was not involved)

Because of the changes to the ISS mission schedule (Soyuz TMA-15M crew not coming home for a few extra weeks), the mission control team had the opportunity to come up with some “get aheads” to take care of while there are still 6 people on ISS. The result is that later this week we will be executing the “PMM relocate”, or moving the large logistics module from one place on ISS to another, to free up a new docking port. This animation should help:

This is the first large module relocation like this since the end of the Space Shuttle program. The activities will be covered on NASA TV this Wednesday, May 27th.

Here’s the view through the Node 3 forward hatch where PMM will be berthed:

ESA’s Rosetta spacecraft is still orbiting comet 67P/Churyumov-Gerasimenko.  Recently they released some pictures showing some boulders that appear to be “balancing” on their ends, due to the strange gravity field. The direction of “down” is highly dependent on your location on this strangely shaped object, causing configurations that would not be possible on a round world.

Here’s a new higher resolution view of the “bright spots” on Ceres.

Here’s a video of the sun setting on Mars, in real-time, as recorded by the Curiosity rover on Mars (via the Planetary Society).

This post will have to cover the last two weeks, as I missed last week’s update partly due to being on the evening shift at the ADCO console. I happened to be on duty in mission control when the lost Progress cargo ship re-entered the Earth’s atmosphere over the Pacific. Unfortunately, ISS was too far away for us to see anything from the onboard cameras.

Down to Earth

The crew of Expedition 43 will not be coming back down to Earth as planned this month. NASA and the other ISS partners announced this week that upcoming crew rotation dates will be delayed due to the ongoing investigation of the Progress resupply craft that failed to reach ISS. The next launch was also postponed by a couple of months.

Fortunately, the astronauts aboard ISS seem to be in high spirits and are making the best of it:

In a seemingly unrelated announcement, British singer and spaceflight hopeful, Sarah Brightman, has postponed her plans to fly on a Soyuz to the International Space Station, according to a press release on her website. No official word yet if her backup Satoshi Takamatsu will take her Soyuz seat on TMA-18M later this year.

A new astronaut movie called Pale Blue Dot will star Reese Witherspoon. Let’s hope it lives up to the pedigree of its namesake. Based on what little we know about it so far, I don’t know if I am convinced.

Ok, politics out of the way first. A committee in the US House of Representatives recently marked up a version of a budget bill for NASA that funds the agency at healthy levels but takes a bunch of money from Earth science and gives it to the manned exploration programs.

Dr. Dava Newman, of MIT, has been confirmed by the US Senate as the new deputy NASA administrator.

SpaceX will conduct their first Pad Abort Test of the manned version of their Dragon capsule on Wednesday. Details of the test can be found here. The unmanned test will be streamed live on NASA TV. Here are some pictures of the Dragon on the pad waiting for the test.

Also, here is a new awesome picture from the failed droneship landing of the SpaceX Falcon 9 booster last month.

Blue Origin tested their New Shepard vehicle on April 29. The launch got them very close to space, only a few miles short of the Karman Line. Here is a video they released of the test.

SpaceX successfully launched their 5th flight of the year, launching a comm satellite for Turkmenistan on April 27th.

On April 28, a Soyuz rocket carrying an unmanned Progress resupply craft launched from Kazakhstan, headed for the ISS. Unfortunately, a problem occurred at or near separation from the upper stage and the vehicle spun out of control. Mission controllers in Russia were not able to recover the spacecraft and it is expected to crash back to Earth this week. NASA and its partners have a plan for continued logistical support of the space station without the Progress (SpaceX is launching another resupply very soon) and Russia is conducting an internal investigation.

Meanwhile, up on the ISS, the crew has some distractions to keep them from thinking about the logistical challenges. They have installed their brand new espresso machine (or ISSpresso) and also setup a new projector movie screen.

The static fire test happened on Saturday, which is an important milestone before launch. I suspect they won’t stream imagery of the barge landing live (like last time) but hopefully they will have dramatic imagery of a success or failure to share afterwards! Among other cargo, food, and science that this CRS-6 mission is hauling to the ISS, there is also a cubesat known as Arkyd-3, which is a demonstration mission for the asteroid mining company Planetary Resources.

I recently finished reading both Zero Phase and Public Loneliness by Gerald Brennan. Check them out!

The most exciting space news since my last post on March 20th of course was the launch of Soyuz TMA-16M last Friday. Here’s a video of the launch. More on what’s been going on ISS under “In Orbit”, below.

Down to Earth

United Space Alliance is having a public contest to vote on the name of their new rocket, which they hope will replace their medium lift Atlas V and Delta IV rockets by the 2020s.

Speaking of naming contests, the SETI Institute has launched the “Our Pluto” campaign for the public to help suggest names for features on Pluto, which will soon be discovered by the New Horizons spacecraft. From what I can tell, NASA and the IAU are onboard, so the names may actually become official.

Ellington Airport, just a few miles from the Johnson Space Center, has a new agreement with Sierra Nevada Corporation to land unmanned Dream Chaser spaceplanes here in Houston. If Sierra Nevada is awarded the CRS-2 contract, this could provide a nice logistical advantage for the ISS program.

The next SpaceX Falcon 9 launch, which is another cargo resupply flight to ISS, has been delayed to April 13 (a 3-day slip).

NASA has selected “Option B” for the Asteroid Redirect Mission (ARM). The mission will involve an unmanned robotic mission retrieving a small boulder from the surface of a Near Earth Object (NEO) which will be visited later by astronauts in lunar orbit.

In Orbit

Lots of rocket launches in late March, in addition to the Soyuz launch that sent Scott Kelly, Mikhail Kornienko, and Gennady Padalka to ISS. The list of launches includes: an Atlas V with a new GPS satellite, A Japanese reconnaissance satellite on an H-II rocket, two European Galileo navigation satellites on a Soyuz rocket, and at least one other Indian, Russian, and Chinese rocket. The Chinese launch reportedly included a test flight of a new mini-space plane. The number of rocket launches this year now stands at 21 to orbit, with no failures.

As for that Soyuz flight to the ISS, it was a picture perfect launch, rendezvous, and docking, with Kelly and crewmates arriving at ISS only 6 hours after departing Kazakhstan. The number of humans off-world is now back up to 6, and the number of people tweeting from space is now at 4, with Kelly joining Cristoforetti, Virts, and Shkaplerov.

Last week, on Wednesday, March 11th, Orbital ATK conducted a successful static test fire of one of the solid propellant rocket motors that will be used for the SLS rocket.

The next day, on the 12th, the Soyuz carrying Butch Wilmore, Elena Serova, and Alexander Samokutyaev returned to Earth. Check out these incredible pictures of their descent and landing. Looks like it was a beautiful (cold) day in Kazakhstan.

With Butch and crew on the ground, Expedition 43 is underway with only three crew members onboard – Terry Virts, Samantha Cristoforetti, and Anton Shkaplerov. They are a good trio to have onboard together, as they are all very active on Twitter, providing us awesome views of Earth from on orbit! However, they will be joined very shortly by Scott Kelly, Gennady Padalka, and Mikhail Korniyenko who are launching next Friday, March 27th.

On March 18th, many space fans celebrated the 50th anniversary of the first ever spacewalk, conducted by Alexei Leonov on the Voskhod 2 mission.

Leonov is 80 years old, and did a press circuit for the occassion!

In less fun news, there has been a lot of talk about a couple of space-related hearings in Washington, D.C. that happened earlier this month. Let me break it down into the biggest talking points for you:

1. On March 4th, NASA Administrator Charles Bolden appeared before the “House Appropriations Committee” for a budget hearing. Some folks latched on to a discussion between Bolden and Congressman John Culbertson about whether NASA has a plan for ISS if Russia decides to no longer participate. Given that the program is a joint venture that depends on both parties, it seems to me like an unfair premise.

2. On March 12th, Bolden appeared before the “Senate Subcommittee on Space, Science, and Competitiveness”. One of the big takeaways was Bolden’s comments about why the Opportunity’s rover’s budget is being cancelled in 2016. The Planetary Society has a pretty good explanation of why that is a bad idea.

3. In the same hearing, Bolden was asked by Texas Senator Ted Cruz why NASA spends so much time on Earth science instead of exploring space. Of course, Earth science is part of NASA’s core mission. Parabolic Arc explains why Ted Cruz doesn’t seem to know what he is talking about.

4. Lastly, the senate held an “Army and Air Force hearing” on March 18th. There was some discussion about the RD-180 engine issues (see my earlier post) and whether the Air Force could provide a replacement by the 2019 deadline. USAF and ULA officials say it is not possible. Some of the senators scolded that no progress has been made. However, Aerojet recently conducted a test of their new AR1 engine, which may be a starting point for a replacement.

In Orbit

I will optimistically put this news in the “in orbit” section: with bids on the CRS-2 (commercial resupply services) contract due, both Lockheed Martin and Sierra Nevada have been promoting their ideas for how to get cargo to and from the ISS. Lockheed Martin has a unique design involving a reusable cargo ferry that stays in orbit and transfers cargo to a rocket stage with a robotic arm. Sierra Nevada is proposing an unmanned variant of their Dreamchaser spaceplane, which recently lost out on the ISS crew transfer contract (CCtCAP).

Speaking of ISS cargo, NASA has extended the contracts with SpaceX and Orbital ATK by a few additional flights in 2017 to close the gap between CRS and CRS-2.

Alright, back to the fun stuff. Up in space, the pretty pictures from the ISS crew just keep on coming:

Today there is a total solar eclipse in the Northern Atlantic and Arctic. Hopefully the astronauts can get some views from the ISS! In fact, Cristoforetti just posted the below picture just a few minutes ago, as I write this.
