SpaceX successfully conducted the static fire test for their next rocket launch from Pad 39A at the Kennedy Space Center. A Falcon 9 carrying a commercial satellite will liftoff very early Tuesday morning, March 14th.

In Orbit

Only one orbital rocket launch since my last post. A European Space Agency Vega rocket launched the Earth-observing Sentinel-2B satellite from French Guiana on March 7th.

As usual, there are lots of good pictures from the crew on the ISS to share. Here’s a selection.

New data from the Dawn probe in orbit of Ceres indicates that the “bright spots” are much younger than the craters they inhabit. This is evidence of relatively recent cryovulcanism.

Check out these incredible images of Saturn’s tiny moon Pan. It has a unique shape no one has ever seen before.

Astronauts Mike Fossum and Mike Baker announced their retirement from NASA last week.

NASA announced that it will be funding two new robotic missions to study distant asteroids. The Lucy probe will take many years to go all the way out to study the Trojan asteroids, which share Jupiter’s orbit. The Psyche probe will travel to an asteroid named Psyche which is a solid iron asteroid. It will be the first large iron asteroid visited by a spacecraft.

In Orbit

The one and only orbital launch since my last post on January 5th was yet another Chinese rocket. This launch on the 9th carried several small Earth observation satellites into orbit.

Up on the ISS, the Expedition 50 crew completed two successful spacewalks to upgrade a portion of the space station’s power systems to use new lithium-ion batteries. Last Friday, January 6th, Peggy Whitson and Shane Kimbrough completed the first spacewalk and yesterday, Friday, January 13th, Shane Kimbrough and Thomas Pesquet completed the second. Whitson’s 46 hours over 7 spacewalks puts her in an elite class at 14th on the list of most spacewalking hours ever by a human. Shane also has an impressive 25 hours over only 4 EVAs, but it keeps him off this list of top 30 humans on Wikipedia (30th place is just over 38 cumulative hours. Also note that Whitson would only need one more spacewalk on her current mission to pass Sunita Williams’ 50 hours in 7th place for most hours for a woman). Here are some video summaries from NASA and pictures from the spacewalks:

Five orbital launches since my last post on October 30th (see this Wikipedia page for a nice list of all launches this year, with dates, etc.):

Japan launched the Himawari 9 meteorological satellite on an H-II rocket.

China had three launches: the debut of their new Long March 5 heavy-lift rocket on carrying an electric propulsion demonstration payload; a small Long March 11 rocket carrying an X-ray navigation demonstration satellite (read up on pulsar navigation here); a medium-lift Long March 2D rocket carrying a weather satellite.

The fifth launch was a ULA Atlas V rocket carrying a satellite for Earth-observation company WorldView. The launch was from Vandenberg in California.

SpaceX posted an update to their accident investigation regarding the rocket that was lost on a launch pad in September. Here’s a direct link to their anomaly updates page. They hope to return to flight this year.

In Orbit

In launches, it has been a slow couple of weeks, with only two orbital launches since my last post on October 16th. It was quality over quantity though, as both launches were important and anticipated missions for ISS operations.

First, Orbital ATK was able to finally launch their upgraded Antares rocket with a Cygnus cargo craft on its way to ISS. The rocket launched on Monday October 17th and was captured at the ISS almost a week later on Sunday the 23rd. The delay was necessary due a higher priority launch and docking of three crew aboard a Soyuz (see below).

On Wednesday, October 19, the Soyuz rocket carrying the second half of Expedition 50 finally launched (after a spacecraft problem delayed them several weeks). The launch, rendezvous, and docking were flawless. The new crew of Shane Kimbrough Andrei Borisenko, and Sergey Ryzhikov arrived at ISS on the 21st.

There were 8 people in space only briefly (recall that two Chinese taikonauts are hanging out on their own space station right now). Expedition 49 had to hand over command to new Expedition 50 commander Kimbrough on the 28th before Anatoli Ivanishin, Kate Rubins, and Takuya Onishi undocked on Saturday night and landed safely a few hours later.

Speaking of the Chinese taikonauts, they docked successfully to the Tiangong-2 space station on October 20th and plan to stay for several weeks.

Around the Solar System

The ExoMars mission arrived at Mars on October 19th. The orbiter (known as TGO – Trace Gas Orbiter) made a successful orbital insertion burn but unfortunately, contact with the Schiaparelli lander was lost at the planned time of touchdown. The lander is suspected to be lost, but NASA’s Mars Reconnaissance Orbiter (MRO) was able to image the lander’s crash site, which should help with investigations. Below is an animated GIF showing the recent appearance of the lander in MRO imagery:

And here’s a closeup from the MRO’s HiRise camera.

In other bad news, the Juno spacecraft went into safe mode during its closest approach to Jupiter on October 18 and was not able to obtain scientific data. This came only a few days after an engine burn had been cancelled. Fortunately, mission controllers were able to command Juno out of safe mode on October 24 and perform at least one “trim” maneuver. The mission timeline will be impacted by the problem but there are still dozens of orbits left in the primary mission to gather data.

Here is a nice post with images about the preliminary results from Juno so far.

Speaking of spacecraft beaming data back to Earth, the data downlink from the New Horizons probe of its Pluto flyby last July has finally completed, 15 months later!

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!

Also returning to Earth this month, but in a more controlled fashion, was there astronauts aboard Soyuz TMA-19M: Tim Peake, Tim Kopra, and Yuri Malenchenko.

Here are all the orbital launches since my last post on June 6th:

  • A Russian Proton rocket carrying a communications satellite (June 9).
  • A ULA Delta IV rocket launch from Florida carrying a spy satellite (June 11).
  • A Chinese launch of one of their navigation satellite (June 12).
  • A SpaceX Falcon 9 rocket with two communications satellites (June 15).
  • A European Ariane 5 rocket carrying two communication satellites (June 18).
  • An Indian PSLV rocket carrying a slew of satellites including a flock of PlanetLabs Doves (June 22).
  • A ULA Atlas V rocket carrying a US military communications satellite (June 24).

The SpaceX launch, as usual, was the most exciting, with another ASDS landing attempt. They missed the landing this time. Here are some pictures of the wreckage returning to port.
