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:

Around the Solar System

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 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.

The next SpaceX resupply flight to ISS will now be on June 28.

NASA’s “Europa Clipper” mission, which will explore the icy moon of Jupiter, has moved on to development phase.

US Senator from Texas John Cornyn visited mission control last week.

In Orbit

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.

Jack King, who provided launch commentary for NASA missions in the 1960s and 1970s, has died at 84.

The United States Senate is busy working on a markup of a budget in the Commerce-Justice-Science (CJS) subcommittee, which includes money for NASA. The current budget, if passed, would include about $18.5 billion for NASA. However, there is some debate about how that money is being spent, including whether enough money is being allocated to the “commercial crew” program for launching astronauts to ISS on spacecraft built by SpaceX and Boeing.

NASA has awarded $30 million to SpaceX for their launch abort test milestone last month.

NASA’s Low Density Supersonic Decelerator (LDSD) had a second drop test over Hawaii this week. The technology will help with Martian EDL for large mass spacecraft. Unfortunately, the parachute failed at high altitudes. More test flights are planned.

It was a very busy week up on the ISS. The most important update is that Expedition 43 ended on Wednesday when Terry Virts handed over command to Gennady Padalka for Expedition 44. Then on Thursday morning the crew of TMA-15M (consisting of Terry Virts, Samantha Cristoforetti, and Anton Shkaplerov) undocked from the ISS and landed safely in Kazakhstan a few hours later.

Earlier in the week, there was some unrelated excitement: first, on Monday, June 8th, the mission control teams in Moscow and Houston had to work together to execute a Pre-determined Debris Avoidance Maneuver (PDAM) to change the ISS orbit to dodge some space junk.

Then, on Tuesday, an unexpected thruster firing from a docked Soyuz vehicle caused ISS to take contingency actions. The Soyuz thruster firing overwhelmed the NASA-owned Control Moment Gyroscopes (CMGs), requiring use of Russian Segment attitude control thrusters to “right the ship” so to speak. Long story short, this is exactly the kind of contingency we plan for and practice hundreds of times in the ADCO group. From what I have heard, the situation was handled very well!

With Expedition 44 underway, there are only 3 astronauts aboard ISS. According to official launch dates from Roscosmos, we won’t see 6 people aboard again until TMA-17M launches in late July.

The LightSail mission has been declared a success, now that there are images of the mylar solar sails deployed! Can’t wait for the next test flight next year.

Half of the Expedition 43 crew will finally return to Earth this week aboard their Soyuz TMA-15M spacecraft. This will start Expedition 44 with a 3-man crew of Padalka, Kelly, and Kornienko. NASA TV will cover the undocking from ISS on Thursday morning, June 11. The undocking was delayed last month due to the launch failure of an unmanned Progress spacecraft. Due to the extended mission, Samantha Cristoforetti now holds the record for the longest spaceflight by a woman.

On Friday, June 5, a Russian military satellite launched on a Soyuz 2a.1 rocket. This launch is notable because it is the first flight of a Soyuz rocket since the launch failure of the Progress spacecraft. Flights of unmanned Progress and manned Soyuz spacecraft to ISS both launch on the Soyuz family of rockets.

Speaking of Soyuz, check out this awesome timelapse from the TMA-16M docking to ISS earlier this year.

The Planetary Society has confirmed via telemetry that their LightSail’s solar sail has deployed. No photos or video available yet.

Here’s another cool video from a GoPro mounted to the inside of a Falcon 9 payload fairing after a recent launch. The video starts after the fairing has already separated from the rocket.

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!

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.

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.

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.
