Down to Earth

An opinion piece by Barack Obama appeared in CNN last week discussing his vision for America’s future in space and particularly, future missions to Mars.

Amid talk of a schedule slip of the first Starliner missions, Boeing announced they will need to add an aeroskirt for their launch configuration atop the Atlas V rocket (follow the link for an illustration).

In Orbit

Astronauts on the ISS opened up the BEAM module for another round of inspections (that’s the “expandable” module that was added back in May). Meanwhile, NASA announced that it is seeking commercial partners to build new functional modules for the ISS. Of course, the supplier of BEAM, Bigelow Aerospace, is one of the companies seeking the contract.

The launch of Orbital ATK’s Antares rocket (returning to flight almost 2 years after the last one failed after launch) was delayed until tomorrow evening due to a technical issue.

Earlier this evening, China launched a manned Shenzhou capsule with two crew aboard. They are heading to the new Tiangong-2 space station for an extended mission. When the latest ISS Soyuz crew launches in a couple of days, there will be 8 people in space! It has been very rare for the number to grow above 6 since the last Space Shuttle mission five years ago.

Around the Solar System

Due to some sticky valves in the Juno spacecraft’s propulsion system, the probe will not be making a scheduled burn to reduce its orbital period from over 50 days to just 14 days. NASA is waiting another orbit (so, until December) to investigate and then try again.

Astronomers have discovered a new distant unnamed object (2014 UZ224) which may be large enough to qualify as a “dwarf planet”. The object is smaller than Pluto and orbits about 5 times farther from the sun.

The ExoMars/Schiaparelli mission – a joint mission between ESA and Roscosmos – had some critical mission events today, including separation of the Schiaparelli lander and a critical orbital maneuver to setup for orbital insertion next week.

Jack Garman, who worked a support console for Apollo guidance and navigation, passed away on September 20th, at 72 years old. Garman is best known as being instrumental in the calls to proceed with landing on Apollo 11 when some guidance computer program alarms showed up at just 3,000 feet above the surface. Here’s the raw audio from that part of the landing which is always worth listening to again. Great example of flight control in action.

Neil Degrasse Tyson’s podcast StarTalk had a special episode hosted by astronaut Mike Massimino with guest interviewees, flight directors Royce Renfrew and Emily Nelson. Check it out here!

Musician and singer Grace Potter collaborated with NASA on a music video for her song Look What We’ve Become. It was filmed completely at NASA’s Johnson Space Center! Check it out below.

One of the biggest national stories of the last week was Hurricane Matthew, which came close to dolling out a devastating blow to the East coast of Florida. Fortunately, the most dangerous winds stayed offshore as it passed the Kennedy Space Center, resulting in some damage but nothing too serious.

In the battle of the New Space giants, there were two big stories in recent weeks. First, SpaceX CEO Elon Musk had his much anticipated presentation at the International Astronautical Congress (IAC) in Mexico. the speech presented a high level framework of his plans to visit Mars. Most of the details were focused on the rocket design and less on how humans would survive and thrive on Mars. Below is the full length video, but Ars Technica had a good analysis if you don’t want to watch all of it. Another good take on it from Phil Plait here.

If you are interested in just the 4-minute animation from SpaceX showing their imagined Mars mission architecture, jump to the second video below.

The other big story was Blue Origin’s successful in-flight abort test of their New Shepard rocket (personally, I am not sure if they have a separate name for the capsule or if New Shepard refers to the whole system. It was a pretty exciting launch and test. Jump to 51 minutes in the webcast replay below to watch!

In Orbit

Lots of good news regarding the ISS flight manifest. The next Cygnus cargo freighter, launching from Virginia for the first time in 2 years on Orbital ATK’s redesigned Antares rocket, should fly next Thursday, the 13th.

The following week, the next crew should launch on their repaired Soyuz craft. That launch is scheduled for Wednesday, the 19th.

There were two rocket launches since my last post. First, an Indian GSLV rocket launched a slew of satellites into orbit, including some from Algeria, USA, Canada, and India. Second, an ESA Ariane 5 rocket launched two communications satellites to a geosynchronous orbit on the 5th.

Around the Solar System

Check out this “video” (really an animated gif made from stills) of the Curiosity rover drilling on Mars! The rover has just officially entered its next two-year mission extension.

NASA announced new findings from the Hubble Space Telescope that reinforce the conclusion that not only does Europa have a subsurface ocean of liquid water, but that the water regularly exits the moon in powerful plumes (which could be theoretically sampled by a visiting probe).

In even more exciting planetary science news, NASA announced new analysis of data from the MESSENGER spacecraft (which finished its Mercury orbital mission last year). By analyzing imagery from the last part of MESSENGER’s mission, when it was at a lower altitude, scientists have concluded that the surface shows signs of recent contraction, meaning that Mercury is tectonically active.

ESA’s Rosetta mission ended on September 30th with a controlled descent into comet 67P/Churyumov/Gerasimenko.

Down to Earth

The next manned Soyuz launch has been delayed. The second half of the Expedition 49 crew was due to launch to ISS on September 23rd but technical issues have pushed the launch back.

In another delay, a wildfire in California has pushed back a launch of an Atlas V rocket from Vandenberg Air Force Base.

Legendary cosmonaut Yuri Malenchenko, who has flown to space 6 times and is only second to Gennady Padalka for time in space at 827 days, has reportedly retired. He was most recently on ISS for Expedition 47 earlier this year.

A ridiculously large meteorite fragment was extracted from the ground in Argentina.

Three successful rocket launches in the past week: Israel launched a spy satellite on the 13th; China launched their new space station, Tiangong-2, on the 15th; Arianespace launched a Vega rocket with two commercial payloads on the 16th.

Up on the ISS, Kate Rubins donned a special flight suit painted by pediatric patients from MD Anderson’s Cancer Center. Kate was wearing the suit for a special event arranged by the “Space Suit Art Project” championed by retired astronaut Nicole Stott. The video of the event is below.

Down to Earth

Easily the top story of the past couple of weeks (sorry, OSIRIS-REx) was the loss of a Falcon 9 rocket with its commercial satellite payload on the pad during a pre-launch static fire test (video below). The pad, Space Launch Complex 40 (SLC-40) was damaged in the fire (pictures here) and SpaceX is currently still investigating the cause. It is impossible to speculate on what kind of setback this will cause in their launch manifest until some notion of the cause is determined. SpaceX still has one operational launch pad in California.

Just 3 days before the SpaceX pad fire, the Chinese space program suffered a failure in what is apparently the first launch failure of the year. The Long March 4C rocket was expected to put a reconnaissance satellite in orbit.

As for positive news, NASA’s troubled Mars lander InSight has been greenlit for a launch sometime in 2018.

Another goodie was Virgin Galactic conducting the first test flight of the new SpaceShipTwo (although just a captive carry flight).

Check out this blog post from one of the recent crew members of NASA’s asteroid mission simulation, HERA. Tess was on the crew of HERA 11.

The most important thing to come “down to Earth” last week was the crew of Expedition 48. Jeff Williams, Oleg Skripochka, and Aleksey Ovchinin landed in Kazakhstan last Wednesday after a flawless undocking and re-entry.

In Orbit

Before Expedition 48 ended, Jeff Williams and Kate Rubins conducted their second spacewalk in as many weeks, repairing and upgrading a slew of items outside the ISS.

Fortunately, there were at least two successful launches to offset the failures in early September. First, an Indian GSLV Mark II rocket lofted a weather satellite. Secondly, a ULA Atlas V rocket launched NASA’s OSIRIS-REx probe on its 7-year journey to visit an asteroid and return to Earth with samples.

Around the Solar System

On Mars, the Curiosity rover is currently trundling through some incredible landscapes, snapping photos of beautiful buttes and rock layers.

Juno continues to return data from Jupiter, including a stunning image of the north pole.

And last but not least, one of the coolest stories of the last week, the European Space Agency finally located the lost comet lander, Philae, just weeks before the orbiter Rosetta is due to end its own mission. Check out the pictures!

It was space capsule drop test week, with an Orion drop test in water and a Boeing Starliner drop test on land, both at NASA Langley.

Here is video of the Starliner crew access arm being installed earlier this month:

SpaceX recently erected their first flown and recovered Falcon 9 rocket first stage’s as a display piece at their factory in California.

Veteran NASA astronaut Terry Virts has retired from NASA. Virts flew on one space shuttle mission (STS-130) and one ISS expedition (42/43) for a total of 213 days in space including 3 EVAs.

On August 19th, ISS astronauts Jeff Williams and Kate Rubins exited the ISS airlock for a 6-hour EVA to attach the new International Docking Adapter (IDA) to the front of the station (along with a few other tasks). The spacewalk went well so Williams and Rubins will conduct their second as planned on September 1st. Below are two videos, a 3-minute summary of the August 19th EVA and then a long press conference discussing the upcoming EVA. Jump to 8 minutes into the press conference for a narrated overview of the EVA.

Jeff Williams recently broke the American record for total time in space, besting Scott Kelly’s 520 days. Williams has launched to space four separate times. Kelly visiting mission control last week to congratulate Williams:

There were three more successful rocket launches since my last post on August 15th. First was a Chinese rocket with a main payload of an experimental quantum navigation satellite. Second was a Delta IV rocket carrying payloads for the U.S. Air Force. Last was a European Ariane 5 rocket with two telecommunication satellites.

Around the Solar System

NASA recently recovered contact with the STEREO-B satellite, which is one of a pair of Sun-observing probes that was lost a couple of years ago.

NASA’s Jupiter orbiter, Juno, completed close approach during its first orbit. This will be Juno’s closest approach to Jupiter during the nominal mission. We should get some great shots from the onboard JunoCam soon!

You should check out the work of Sean Duran, who is inserting accurately scaled astronauts into Mars rover Curiosity’s pictures to help us get a better feel for what Mars would really look like.

Out There

In what may very well be the biggest science story of the year, The European Southern Observatory (ESO) in Chile announced their findings that a small terrestrial world orbits in the habitable zone of Proxima Centauri, a red dwarf star which orbits Alpha Centauri at a distance of 0.1 light years, and is the closest star to Earth at about 4.2 light years away.

Meanwhile, the next generation of crew access arms, for Boeing’ Starliner capsule, was delivered to the Atlas V pad in Florida.

SpaceX conducted a full duration test fire of one of their recovered first stage boosters. Here’s the video:

Google Lunar X Prize competitor, Moon Express, has received approval from the United States government for their private mission to land a rover on the moon.

Vector Space Systems completed their first successful sub-orbital launch.

In Orbit

Speaking of launches, there were four successful orbital flights since my last post. This brings the year’s total to 50 for 50 on orbital launches. For comparison, 2015 had 87 total with 5 failures.

First was an Atlas V launch from Cape Canaveral carrying a secret payload for the National Reconnaissance Office.

Second and third were two chinese launches carrying a new communications satellite and a radar imaging satellite.

Lastly was the SpaceX Falcon 9 launch early in the morning ofAugust 14. The rocket successfully delivered the Japanese JCSAT communications satellite to orbit and recovered the first stage booster on the ASDS at sea. Very impressive. This brings SpaceX’s year up to 8 successful launches for 8 attempts – a yearly record already in August – and 5 for 8 on booster recovery.

Coming up next week is a spacewalk on ISS by NASA astronauts Jeff Williams and Kate Rubins to install the new International Docking Adapter.

My recent trip to LA

I love that the world can be both so small and so large. I don’t mean that you find yourself on vacation in Rome surrounded by millions of strangers and happen to bump into an old college friend (although those kinds of coincidences can feel quite odd). I’m referring instead to expecting to run into an old friend in a strange city because over time you seem to know someone everywhere. Family and friends move around for so many reasons – career, cost of living, or whim – and the older you get the more likely it is that you can fly to a particular city and have a friend to call on.

Now that I’ve been out of college for a number of years, I’ve realized that the same thing happens in any given field or interest area. Stay in an industry long enough and people you went to college with, worked with, interned with, or whatever, will tend to move around until you can find an acquaintance at all the important companies or institutions.

This made itself apparent this past weekend on a quick trip to the Los Angeles area to visit some friends and family. My wife and I weren’t in town at all for geeky reasons – we just wanted to see some old friends who deserved a visit – but space follows me these days. It’s not exactly amazing that we know some folks that work at Virgin Galactic and SpaceX. They are old engineering friends from high school and college, after all. But just because I know someone from SpaceX – who very, very graciously offered us a quick tour of the main factory – doesn’t mean I am somehow an insider. It just means I know someone. This is a hard concept for a lot of people in this world to realize and is why you end up with groupies and name-droppers and people like that. A person needs a good dose of humility to avoid the slippery slope that leads to vanity.

This was one of those "seeing a friend in Rome" coincidences

The last Space Shuttle External Tank also happened to be in town

I received my needed dose of humility when I was led down the hall from the visitor entrance at 1 Rocket Road, around the corner past mission control, out under a flown Dragon capsule, and saw the assembly lines of tanks, engines, and spacecraft in SpaceX’s flashiest factory. After a lifetime of being a space geek, 4 years in college, a couple of internships, and 7 years working at JSC, somehow I hadn’t realized that I’d actually never visited a facility where rockets are being built.

My mind had somehow glossed over this with the illusion that I had. After all, I have been to all the famous NASA rocket parks at JSC, KSC, and MSFC, not to mention each of National Air and Space Museum’s locations a number of times. I’ve seen rockets; I’ve seen a space shuttle launch; I’ve seen a Falcon 9 launch; I’ve been inside the VAB on a tour. But seeing those places is quite different from walking into a facility where photography is not allowed (another concept foreign to me from my years at JSC) and seeing an assembly line of Merlin 1 rocket engines getting ready for integration into the famous Falcon 9 “octaweb.” The images of massive tanks being welded, payload fairings being laid up, and Dragon capsules being integrated, are burned into my mind. I have no illusions that the factory is deliberately designed to leave me in awe. But it doesn’t matter. The point probably would have been made just as well at the ULA or Orbital ATK factories: it’s a big damn world.

Flight hardware! (Photo via Steve Jurvetson’s Flickr)


I felt absolutely ignorant walking around that factory. I have a degree in aerospace engineering and yet many of the details of what I saw on Saturday escape me. The world is big in both these gulfs of knowledge, but also the gulfs of time and experience. I last saw my high school classmate at least many years ago, if not a decade. His experience at SpaceX, watching it grow from a struggling startup in 2008 to a dominant industry force today, is vastly different from my experience in a steady job at NASA, surrounded by the always present glory of manned spaceflight but also at the whims of politics, and the morale roller coaster that provides. He has hands on knowledge of spacecraft design, while I am one of some hundreds of people in the world who know what it is like to operate a modern manned spacecraft. This is the largeness of the world that hit home for me last Saturday.

And yet, sitting and chatting over a meal with several Virgin Galactic employees gave me a feeling of smallness, like we are all in this together regardless of badge or funding source. It occurs to me now that networking is not important just for selfish reasons of career growth. It is also important to stay out of the trap of living in a bubble, of thinking that your little slice of the world is the most important. I can’t feel good about what I do without the context of how it fits into the bigger picture of what everyone is doing, not just in Houston and Los Angeles but around the world.

It is all too easy to let the size of the world become overwhelming. How can I have an influence among 5 million people in my city? A hundred million in my country? Seven billion in my world? How can I have an original idea? Surely I am not the only one to have thoughts like these from time to time. One way to make the world small again is to create and preserve relationships with other people doing the things you care about. They might show you some “flight hardware” and then you will be hard pressed not to feel motivated.
