NASA has selected five new flight directors for manned spaceflight programs.

Last week in Houston a new opera titled ‘O Columbia’ premiered for just two nights at the Houston Grand Opera. The production incorporated the tragic loss of Space Shuttle Columbia in the second act. I didn’t get to see the show, but according to The Houston Chronicle a preview at the Johnson Space Center received a standing ovation.

Don’t forget to go out Sunday evening, September 27th, and see the lunar eclipse!

Two more orbital rocket launches last week. The first was a Rokot launch vehicle from Russia with several military communications satellites. China seems to be on a roll this month and launched another new rocket, the Long March 11, with several cubesats.

On Monday, September 28th, the Japanese HTV5 cargo vehicle will leave the ISS. You can follow along on NASA TV.

Since it’s a bit of a slow week for spaceflight news, here are some cool pictures from ISS as filler!

Tonight, the Expedition 44 crew of Gennady Padalka, Andreas Mogensen, and Aidyn Aimbetov will undock from the International Space Station and land in Kazakhstan. Follow along on NASA TV, with undocking at 5:29 PM Eastern.

During his short stay on ISS, Mogensen has been very busy trying to get as much science and engineering done for the European Space Agency as he can, including remotely operating a robot on the ground from space! Very cool.

Here’s a quick video from Mogensen about living in ESA’s Columbus module on ISS.

Early Friday morning, the European Space Agency launched a Soyuz rocket with two Galileo satellites into orbit. Galileo is ESA’s analog to the American launched GPS navigation system. Galileo is up to 10 satellites in orbit, but it will take many more to have a complete system (GPS has 31 active satellites).

All of the big events last week up at the ISS went fine. First, on Monday, HTV5 rendezvoused with the station on time and was captured with Canadarm-2. Later in the week, the crew of Soyuz TMA-16M strapped into their re-entry couches for a quick 30 minute fly around to change docking ports. Here’s an awesome time lapse of the “relocate”.

A few orbital rocket launches this past week, but none related to the ISS program. Here’s a rundown of the three launches from three different nations: India launched a communications satellite on a GSLV rocket, China launched a military satellite on a Long March 4C rocket, and Russia launched a commercial communications satellite on a Proton rocket. An Atlas V was supposed to launch from Florida with a military satellite but was delayed due to tropical storm Erika.

Here’s a nice animation by ESA about astronaut Andreas Mogensen’s flight to ISS next week. Soyuz TMA-18M is slated to launch with the next ISS crew on Wednesday, September 2.

As usual, lots of good photos from the ISS were posted to Twitter by the current crew, including some great shots of active tropical storms and hurricanes. Here’s a selection.

Veteran astronaut Steve Swanson, who flew on the space shuttle and commanded the ISS last year, is retiring from NASA. According to his Wikipedia page, he has spent an impressive 195 days in space with almost 28 hours of spacewalk time across 5 EVAs. This leaves NASA with 45 active astronauts (which doesn’t count ESA and JAXA astronauts who are qualified to fly to ISS).

Last week an important engine test in the development of the new SLS rocket was conducted at Stennis Space Center. The RS-25 engine was run for almost a full ten minuets. Here’s a video (test starts at 31:15).

Last Monday, August 10th, two Russian Cosmonauts went outside the ISS for a spacewalk. Padalka and Kornienko spent about five and a half hours outside. It was Padalka’s tenth spacewalk, which should put him nicely on this list once it is updated.

Later in the week, on Friday morning, a Russian Progress cargo craft undocked from the aft port of the ISS. That port will be empty until Soyuz 42S does a “relocate” from the Poisk port later this fall. The relocate is needed to free up Poisk for the docking of the next Soyuz. There will be three Soyuz onboard for a direct handover this fall.

Some cool stuff happened inside the ISS this past week as well. The astronauts were able to eat some red romaine lettuce grown on the space station in the “VEGGIE” experiment.

Japanese astronaut Kimiya Yui did some remote robotics experiments.

The launch of the next ISS resupply flight from Japan has been delayed to Monday, due to bad weather.

Also in ISS cargo news, Orbital Sciences announced they will launch not just one but two or more of their Cygnus cargo resupply missions on someone else’s rocket. Orbital is working hard to recertify their Antares rocket with new Russian engines, following the loss of one of their rockets last October. In the meantime, they are buying Atlas V rockets from United Launch Alliance in order to fulfill their NASA contract.

Here’s the companies official statement on their investigation so far. They have found that a structural support (or “strut”) holding up a pressurant tank in the second stage failed. Elon Musk hopes a delay of only a few months to their manifest.

Three launches from the Earth’s three spacefaring nation’s this past week: first, a Russian Soyuz rocket launched from Kazakhstan on July 22nd, followed a few hours later by a successful docking to ISS. The crew is now back up to full strength of 6, with the addition of Oleg Kononenko, Kimiya Yui, and Kjell Lindgren. Lindgren and Yui are on Twitter, so you should follow my “people in space” Twitter list.

Second, a Delta IV rocket launched from Florida on July 23rd. The mission delivered a new military communications satellite to orbit.

China also had a successful orbital launch last week. A Long March 3B delivered two navigation satellites to orbit on July 25th.

NASA announced the discovery of Kepler-452b, a small planet around a Sun-like star about 1,400 light years distant. This is the most similar planet in size and circumstance to Earth that we have yet found, but it still has 1.6 times Earth’s diameter (mass, and thus surface gravity, unknown). However, the fact that it is so small and in the habitable zone, makes it an awesome discovery.

Obviously the big news this week was that New Horizons had its encounter with Pluto this past week. My space news feed was almost entirely Pluto news starting on July 12th, two days before the encounter. Rather than provide you a dozen links, some of which might be out of date, I would just suggest going over to The Planetary Society blog for up to date coverage of the latest pictures coming in from the outer solar system. Ok, on with some non-Pluto news…

Down to Earth

This week marks the 40th anniversary of the Apollo-Soyuz Test Project, the first joint manned spaceflight between the US and Russia (the USSR at the time). The mission is today remembered as an early precursor to the partnership that led to the ISS. NASA TV did a nice piece marking the anniversary, with interviews with the two commanders: Leonov and Stafford. Check it out! (jump to 9:27 for some prophetic words from President Gerald Ford about the future of cooperation in space)

In Orbit

There was a bit of excitement up on the ISS this week. Early on Thursday morning, Houston time, flight controllers in charge of monitoring the trajectory of the ISS were notified of a debris threat without enough notice to coordinate a debris avoidance maneuver rocket firing. Thus, the crew of Expedition 44 had to execute what is called a “shelter in place”. Essentially, they hunker down in their return capsule until the all clear call. No actual debris strike was noted at the “time of closest approach”.

In less scary ISS news, several sets of cubesats were launched from one of the ISS robotic arms. The spring-loaded launcher was built by the company Nanoracks and the cubesats came from various sources, including one test flight for the asteroid mining company Planetary Resources.

Nanoracks recently announced they will also work with Blue Origin to help them fly suborbital research, building on their experience on the ISS.

The next crewed launch to the ISS from Baikonaur will be on Wednesday, July 22nd. You can see NASA TV’s launch and docking coverage schedule here.

There were two successful orbital launches in the last week, both on Wednesday, the 15th: an Atlas V rocket launched a GPS satellite from Florida and an Ariane 5 rocket launched two satellites (one communication and one earth-observing) from Korou.

Around the Solar System

Of course, I can’t resist discussing Pluto at least a little bit… On Tuesday, July 18th, the NASA New Horizons probe made its closest approach to Pluto and survived, phoning home later that evening. The entire dataset from the flyby will take months to downlink back to mission control over the Deep Space Network, but the initial photographs of both Pluto and its largest moon Charon are enough to surprise and excite scientists with some odd unexpected features on both bodies. Some are calling this a “last first look” now that all the large bodies of the solar system have been photographed up close by spacecraft.

Lean on me

Last Thursday night, I stayed up late like many space fans to watch a “routine” Russian Progress cargo launch to the ISS. This was the 60th flight of a Progress to ISS, clearly a very reliable way to get cargo up there, given that only two previous missions had failed in their objective. But, one of those failures came only about 9 weeks prior, and just 6 days prior a SpaceX Falcon 9 rocket also failed to reach orbit. So despite the apparently reliability of both the Progress vehicle and the Soyuz rocket family, the spaceflight world was on “pins and needles” as Eric Berger of the Houston Chronicle put it.

There seemed to be a theme in the general mood last Thursday about being glad that Russia was able to have a successful launch, but regret that Russia is the country that had to save the day.

This mood is not surprising. Since the last Space Shuttle mission 4 years ago, America’s astronauts have only flown to space on Russian Soyuz capsules. And of course, there are political reasons – unrelated to spaceflight and ISS – that makes people wary to have close ties with the Russian government right now. The loss of two American unmanned flights to ISS in the last year highlights what is an apparently lopsidedness between NASA and Roscosmos when it comes to flying to space.

This whole situation causes the patriot to come out in a lot of people, which is also understandable. Americans have grown accustomed over the last 50 years to NASA being top dog in space. We want our astronauts launching from Florida, not Asia (much harder road trip) and we don’t want our tax dollars going to Russia either. This all makes sense, and I agree. We should all be excited for American space companies being successful, and the commercial crew flights from Boeing and SpaceX can’t come soon enough. Nevertheless, the narrative that somehow Russia has the upper hand is misplaced and frankly doesn’t make sense to me.

This is the narrative that has been a great political point in Washington ever since the end of the Shuttle program but has been used even more over the last year. The phrases people use are that we are “hitching rides” with the Russians or that we are “dependent on” the Russians. Some people are implying that this means the Russians have some sort of power over us. That they are somehow in control of the ISS program politically, and could use it as a bargaining chip if they wanted. In fact, last year Russian Deputy Prime Minister seemed to think that as well when he said that the US should “use a trampoline” to get to space and I even saw a blog article titled “No, Russia did not just kick the US out of the Space Station.”

What I would like to propose is an alternate perspective based up on a more nuanced consideration of what goes on in a partnership. Perhaps the politicians, including Rogozin, do not understand the nuances of what each member country really contributes to the ISS. Yes, right now we are “dependent” upon the Russians Soyuz launch vehicle to get to the ISS. But there is more to operating a giant space station than just getting up there.

Consider my wife (no seriously, stay with me here). Two weeks ago she fractured her right leg playing soccer and has been in a cast. She hasn’t been able to drive, so has been “dependent” on me to get around. I am her only way to work (kind of like the Russian Soyuz is the astronaut’s only way to work). Does this mean I have some kind of power over my wife? Yes, temporarily, but it wouldn’t make sense to exploit that power for a few reasons. The obvious one being that she is my wife and I’m not a jerk, but for the purposes of my analogy, let’s consider the others: while she is dependent on me for transportation and some chores around the house, I am dependent on her for companionship, love, conversation, and wardrobe ideas, not to mention she helps us pay the bills with her equally cool job at NASA! Like any balanced partnership, there is much more going on than just who can drive the car to work. And of course, the cast will come off in about another week and my period of apparent power will be over. What would it gain for our marriage in the longterm for me to somehow use the fact that I have to drive her around to get something I want?

The more I think about it, the more I think this is exactly like the relationship of NASA and Roscosmos in the ISS program right now. Whether you agree or disagree with the decision to retire the Space Shuttle in 2011, it happened and cannot be undone, leaving us in a period of a few years during which astronauts will not be launching from American soil. But we are not in this space business alone anymore. The open-mindedness of the politicians and NASA management who went ahead with the ISS program over 20 years ago has put us in the unique situation of being able to keep our astronauts flying during our period of weakness, if you want to call it that.

But we are not weak. We invented the modern concept of Mission Control and continue to operate the ISS – and the odd Orion flight – from the Johnson Space Center, day in and day out. America has fully seven manned spacecraft* of some type or another in development right now. We operate the critical US Orbital Segment of the ISS without which the ISS could not function. Anyone who thinks it would be a technically simple thing to do for the Russians to “kick us out” and keep the ISS functioning without us (even if such a political move was likely, which I doubt) either doesn’t understand the International Space Station, or is oversimplifying the situation in favor of their politics.

Russia provides critical access to the ISS right now via the Soyuz spacecraft, as well as propulsive support and propellant resupply with the Progress spacecraft. However, just as critical, the USOS provides non-propulsive attitude control with the CMGs, so that the propellant doesn’t get used up so fast that it would be impossible to resupply in time. Also, over half an acre of solar panels on the US segment are needed to power those CMGs – not to mention we ship some of those kilowatts to the Russian Segment, since it has grown too big for its own solar panels over the years.

I could go on. Much of the redundancy of the ISS is built specifically around the concept that the backup system is on the other segment. Sometimes the cosmonauts are even assigned to sleeping quarters in Node 2, on the USOS. The ISS was designed as a partnership from the beginning and our joint interest in continuing our own individual legacies in spaceflight, which has now become a joint legacy, would prevent pretty much anything short of a complete diplomatic breakdown from causing either party to pull out of the program, because it would likely mean doom for the station itself.

So, before you go off on a rant about how its too bad that America is “dependent” on the Russians to get to space, think about whether we should be grateful we are willing to work together despite geopolitical tensions. Perhaps we should be grateful that twice in our time of need, after the loss of an Orbital rocket last year and a SpaceX rocket last month, they quickly launched a Progress resupply vehicle to restock the International Space Station. Perhaps we should be grateful that instead of our astronaut corps being grounded, like it was for 6 years between Apollo-Soyuz and STS-1, that our astronauts continue to fly in space and that our teams on the ground continue to hone their skills as we wait for the big adventures to come with Orion and beyond.

I don’t think we should let the politics and the nationalism overshadow what is really going on here. The International Space Station is just that, international. So to get bent out of shape over sharing rides is kind of counter to the whole point of the thing. Our access to space, to the ISS, is assured specifically because of the redundancy of the partnerships we have built. We have supply lines from America, Russia, and Japan on 4 different rockets. Very soon, our crew access will be from both America and Russia via 3 different rockets. It will be very hard to stop humanity’s access to space at that point. And who knows where we will go from there, together?

Thank you Russia, for letting us lean on you for a little while, as we journey onward.

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!

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.

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!

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.
