Check out this innovative moving ISS tracker someone built.

Chris Hadfield is releasing an album of songs he recorded while on ISS. Here’s a music video of Feet Up off the album.

In Orbit

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.

Around the Solar System

NASA’s New Horizons probe will flyby a Kuiper Belt Object (KBO) known as 2014 MU69 in 2019. The final selection of the Pluto probes next target was announced last week.

What will be the legacy of ISS?

What will be the legacy of the International Space Station? It seems ridiculous to ask at this early stage, with probably a decade of operations remaining. But when you ask the man who was ISS program manager since August 2005, you get a pretty convincing answer. Michael Suffredini, who retired from NASA earlier in August, recently sat down and gave a refreshingly frank interview with Eric Berger of the Houston Chronicle. Simply put, this is a must read if you care enough to have a strong opinion of the ISS and the future of NASA. By the end of the article, not only did Suffredini have me fairly convinced that ISS will have a lasting legacy – leaving in the dust all that talk of station as a “white elephant” – but he had me feeling somewhat optimistic.

Over the past ten years, through all the ups and downs of the ISS, NASA, and this country, Suffredini was the guy who had to deal face-to-face with US politicians, heads of foreign space programs, and CEOs of major contractors. You’d think there’d be a lot of frustration and head-banging involved with those kinds of dealings, and yet Suffredini provides optimistic statements about the two most important players today in the space business other than NASA.

First, when Berger asks if there is any question about the safety of SpaceX’s rockets following their accident earlier this year, Suffredini expresses some pretty strong confidence in the corporation:

And I can tell you, my involvement with what they’ve been doing, they’re taking it very seriously. They’ll do far more mods than are mandatory to fix the problem that occurred. It’s that kind of mindset that’ll allow you to be able to fly crew safely.

Things have come a long way from even just five years ago when the public perception was that NASA didn’t trust SpaceX and SpaceX didn’t want NASA’s help. Such a strong statement as Suffredini’s makes the vision of an affordable and more adaptive future for NASA and the space industry seem very likely.

However, that vision has been thwarted somewhat by shifting federal funding in the area of the ISS commercial crew program. My favorite quote from the interview came from Suffredini’s thoughts on commercial crew funding:

Even our Russian partners would tell you, to have a single crew vehicle to ISS, is not the right way to operate in low-Earth orbit.

I don’t believe this quote is just rhetoric. Suffredini probably had to deal with the heads of the Russian space program on the regular to do his job successfully, so he knows what they think. In fact, if I had to guess, they’ve probably had conversations behind closed doors about this very topic and they probably told Suffredini directly they wished there was more redundancy for crew transportation.

This cuts right to something I have been trying to tell people when the “relying on the Russians” angle of the ISS program comes up. The folks working ISS over in Moscow just want to explore space, same as us. If something unfortunate grounded the Soyuz fleet, everyone would be disappointed – obviously – and I’m sure the Russians would be grateful if NASA had a SpaceX or Boeing capsule ready to go to keep the program on its feet.

So what is the legacy of station? In Suffredini’s answer to that particular question, he only discussed contributions to furthering exploration and learning lessons to get us to Mars. However, in his answers throughout the rest of the interview, he implied much more: international collaboration, catalyzing a commercial space market beyond just satellite manufacturing, and the early success of SpaceX.

Sign me up… oh wait.

The Smithsonian Institution met their funding goal for their Kickstarter project to raise money to restore both Neil Armstrong’s Apollo 11 suit and Alan Shepard’s Mercury suit.

Last week, water tanks were “harvested” from the Space Shuttle Endeavour (on display in California), for use on the ISS.

China recently had a successful engine test of the propulsion system for their new Long March 5 rocket.

The latest ISS resupply mission successfully launched from Japan on August 19th and is on track for a Monday, August 24th, arrival at the space station. Here is NASA TV’s schedule of live coverage.

The European Space Agency also launched a rocket last week. The Ariane 5 rocket launched from the Kourou launch site on August 20th with two communication satellites.

ISS Commander Scott Kelly got a great shot of tropical cyclone Danny last week that got a lot of media attention.

Another amazing picture from the ISS was this picture of lightning which also captured a rare red “sprite” in the upper atmosphere.

The Cassini spacecraft had its last close flyby of Saturn’s small but interesting moon Dione and sent back some of its own awesome imagery.

This awesome Curiosity rover “selfie” from Mars got a lot of press last week. Curiosity recently “celebrated” 3 years on Mars and is still going strong.

If you’re into that sort of thing, you can send your name (and your cat’s) to Mars with the Insight probe, launching next year.

Busy month for ADCO on ISS

It’s always busy on the ISS – there is always at least some kind of exciting science or important maintenance activity keeping one particular set of flight controllers or another working hard. But August has been particularly busy for those of us concerned with visiting vehicle traffic and ISS attitude control. Pretty much anytime anything is coming or going, something comes inside or goes outside (spacewalks, for instance), or you need to test some thrusters or purge some fuel lines, you can bet ADCO is doing something with the ISS Motion Control System to keep the spacecraft nice and stable. Our whole job can be summed up as trying to prevent a LOAC (pronounced “low-ack”), or loss of attitude control.

The period from August 10th to September 11th is a busy final month of Expedition 44 ripe with LOAC-prone activities. Two cosmonauts crawled outside for a spacewalk back on August 10th, which includes an airlock depress that has LOAC potential. The very next day the prop lines for Progress 58 were purged overboard in preparation for the undocking on the 14th. All three of those events required special procedures to keep the station straight and level.

Next week, things are busy again with HTV5 capture and install on Monday, a thruster test for Soyuz 42 on Wednesday morning, and then the Soyuz 42 relocate on Friday, to make room for Soyuz 44 docking on September 2nd. The Expedition ends on September 11th when Soyuz 42 undocks and lands in Kazakhstan.

All of these “complex ops” (to use our common jargon) means extra team members beyond the standard skeleton crew have to staff the consoles in the control centers. The Russian visiting vehicle events can present an extra challenge for the staffing schedule as they often happen in the middle of the night, which is when the ISS tends to pass over the Russian communication ground sites. In ADCO, one of the ways that we try to ease the scheduling complexity is to have a standard rotation of “operators” on the schedule and then if some complex ops fall on a particular day, a “specialist” will volunteer to come in and help out. Generally, we like a two-person team with a front-room and a back-room flight controller, in case anything tricky or unexpected happens.

As a specialist myself, I get excited when the weekly email goes out asking for volunteers for any upcoming complex ops. Working a complex ops shift often means getting to interact with your flight control team colleagues and sending commands to the spacecraft itself. By comparison, a “quiescent” shift for ADCO involves a whole lot of not commanding to the spacecraft, hoping nothing breaks on you, not really talking to anyone, and working on the planning paperwork for upcoming complex ops. It’s of course always awesome to get to work in the mission control center on any shift, but being a part of a team to do something really exciting like dock a new spacecraft is a special privilege.

So, what did I volunteer for then? Well, it actually turns out that I’ll be helping out with all three of the complex ops next week. I’ll be the second shift for the HTV rendezvous (I take over after they’ve already grabbed it but still have to berth it) and then I’ll come back for the Soyuz thruster test and the then the Soyuz relocate itself. I actually keep a list at my desk of which types of events I have worked. Soyuz relocation events are rare and far between, so this is my first opportunity to be a part of one! I actually spent some time today sending myself calendar invites called “sleep” for next week, to make sure I get enough rest in between shifts. I actually didn’t think that was that weird until I wrote it just now. Anyway, while everyone else is looking forward to the weekend, I’m actually looking forward to Monday because that’s when the fun begins!

If you are interested in following along with next week’s events, check out NASA’s TV schedule. There should be live coverage of the HTV capture and then the Soyuz relocation.

Down to Earth

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).

In Orbit

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.

Around the Solar System

Comet 67P/Churyumov-Gerasimenko has reached perihelion (closest point to the sun), which has made the comet rather “active”. Check out these images from Rosetta, in orbit about the comet.

How cool is this? There is evidence of cryovolcanism (ice volcanoes) on Pluto.

Speaking of Pluto, here’s an awesome simulation of the New Horizons flyby in real-time, based on actually imagery from the spacecraft.

If you love the ins and outs of Martian rover exploration, here’s a comprehensive update on what the Curiosity rover has been up to.

Russia recently made it official that they are willing to fund joint operations of ISS through 2024. Meanwhile, NASA sent Russia almost half of a billion dollars to renew the contract for sending astronauts to the ISS on Soyuz spacecraft. The new contract is to protect against further slips in the commercial crew program schedule, as insufficient funds are being allocated by Congress, according to administrator Charlie Bolden.

Astronauts Stephen Frick and Michael Foreman announced their retirement from NASA this week. If you are interested, NASA maintains an updated list of active astronauts here, which can be easily copied into a spreadsheet. With the addition of the class of 2013 as active astronauts, the number is currently at 46 after recent retirements. Interestingly, the oldest class still represented is the class of 1996, of which Scott Kelly (currently in space) and Peggy Whitson and Jeff Williams (upcoming ISS commanders), are all members.

The National Transportation Safety Board (NTSB) released their findings regarding the accident last fall that destroyed the Virgin Galactic SpaceShipTwo spacecraft and one of its pilots. Their findings are summarized nicely at Parabolic Arc or you can read the longer executive summary of the report. In short, it was indeed the “early unlocking” of the spaceplanes “feather system” that doomed the craft. the NTSB’s analysis found that the risk of human error was not properly taken into account during development.

Rumors out of Russia is that a new “Manned Spaceflight Center”, analogous to NASA’s Johnson Space Center, is in the planning stages, and would be headed by former cosmonaut Sergei Krikalev.

Last weekend, on Saturday, July 25th, ISS flight controllers had to command a debris avoidance maneuver to dodge orbital debris that was headed to the ISS.

Last Monday, SpaceX announced preliminary findings related to the loss of a Falcon 9 rocket and its Dragon cargo mission last month. 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.

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.

The other three are Sunita Williams, Eric Boe, and Doug Hurley. Also, the class of 2013 has officially graduated from ASCANs (astronaut candidates) to astronauts, after finishing what is basically their “basic training”.

Follow-up to the launch news from last week: the Progress resupply vehicle launched on July 3rd made it to ISS on the 5th, keeping the supply chains flowing. The next ISS cargo mission is a Japanese HTV flight in August.

Also in rocket news, there was one orbital launch last week from India, carrying several commercial and technology demonstration satellites. Upcoming launches include an Ariane 5 launch from Kourou and an Atlas V launch from Florida, both on the 15th (I use this Wiki page to track launch schedules).

You’ve got to love a good ISS transit photo. Here’s one of the station passing in front of the moon.

It’s time! New Horizons will fly past Pluto on Tuesday! Here is a summary of NASA TV’s coverage of the flyby. The probe gave us a scare last weekend when it went into safe mode briefly, but it is back up and running now and sending home new pictures every day.

One of the latest looks at Pluto

The Dawn spacecraft, in orbit around dwarf planet Ceres, also went into safe mode recently, but was also recovered. Dawn was planning to spiral down to a lower mapping orbit but the issue has delayed that next step in the flight plan.

Mission controllers for the Curiosity rover are dealing with some troubles of their own on Mars. The rovers wheels are continuing to show signs of worsening wheel damage. However, the JPL guys know what they are doing, and they don’t seem too worried yet. Here are some good details from Space.com.
