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.

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.

Pluto’s moon Charon has an odd red polar cap, first seen when the New Horizons probe visited the planet last year. A new analysis shows that the source may be methane from Pluto converted to organics by the sun’s radiation.

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!

Here are all the rocket launches since the last post on June 24th:

  • June 25 – A Chinese Long March 7 rocket debuted from a new launch pad on Hainan Island. The rocket was carrying a demonstration for a future manned capsule design.
  • June 29 – Another Chinese rocket launched, this one with less information available about the payload.
  • July 7 – A Soyuz rocket launched from Kazakhstan carrying three crew members to the ISS.

The Soyuz crew successfully docked to the ISS on Friday night after 2 days in orbit.

NASA’s Juno probe arrived in Jupiter orbit last Monday, July 4th.

Several NASA missions received their official mission extensions. New Horizons was officially approved to continue its mission to the 2019 rendezvous with 2014 MU69 in the Kuiper Belt (we have 3 years to come up with a better name). The Dawn mission at Ceres was extended but it will stay in orbit there instead of moving on to another asteroid.

The Curiosity rover on Mars briefly went into safe mode but has since been recovered.

The Indian Space Research Organization launched their new experimental space plane on May 23rd. The uncrewed vehicle actually didn’t make it to orbit, or even to space, reaching only a peak altitude of 65 km. Still, reaching Mach 5 on re-entry is no joke.

The only other notable rocket launch since my last post on May 9th was a Chinese low earth orbit (LEO) reconnaissance satellite launched on May 15.

Some recent experiments in a Martian atmosphere simulator have given us an update on the Recurring Slope Linae (RSL), which were announced last year as evidence of flowing liquid water on Mars. It may be that ice boiling directly to a gas may be causing the features.

NASA’s flying telescope, SOFIA, has detected atomic oxygen in the atmosphere of Mars. Atomic oxygen is highly reactive and thus can tell us a lot about what is going on at Mars, potentially even the chance for life.

Speaking of Mars, check out this new image from Hubble. Mars is at opposition this week – or the closest approach to Earth – making it a great target for Earth-based astronomers.

Lots of launch activity in the past two weeks. Of the five total launches, I’ll get the two less interesting ones out of the way first: on March 13, a Russian Earth observation mission launched from Baikonaur and then on March 24, a Russian military mission launched from Plesetsk. Both were on Soyuz rockets.

The other three launches are much more interesting. First, on March 14 the much anticipated ExoMars mission launched on a Proton rocket from Baikonaur. The Mars exploration mission is currently safely in solar orbit on its way to an October rendezvous.

On March 18, another Soyuz rocket launched from Baikonaur, but this time carrying 3 people. Aleksey Ovchinin, Oleg Skripochka, and Jeff Williams had an uneventful launch, rendezvous, and docking with the ISS. Or at least, as uneventful as those sorts of things go!

Lastly, an Atlas V rocket launched from Florida on March 23 carrying a Cygnus cargo freighter. Cygnus, named the S.S. Rick Husband by Orbital ATK, arrived (also uneventfully) at ISS on Saturday morning.

Unfortunately, it sounds like Japan’s Astro-H X-ray observatory may have been lost only weeks after it launched in February.
