It’s been a busy and important few weeks in spaceflight. Some major milestones linked below.

Down to Earth

NASA announced nine recipients in the Commercial Lunar Payload Services program.

Virgin Galactic completed a successful powered flight of SpaceShipTwo, reaching over 80 km altitude (note that some organizations define space at 80 km while others define it at 100 km).

In Orbit

Among the launches listed below, the most significant is probably the Soyuz launch from Kazakhstan, which was a return to flight for the ISS program. Cosmonaut Oleg Kononenko and astronauts Anne McClain and David Saint-Jacques launched safely and docked to the ISS.

Meanwhile, the crew from the failed launch in October has been reassigned to a future flight.

There have been 9 orbital launches since my last post on November 25:

  • November 29 – An Indian PSLV rocket launched carrying an Earth observing satellite.
  • November 30 – A Russian Rokot rocket carrying communications satellites.
  • December 3 – A Russian Soyuz rocket launched with three crew headed for the ISS.
  • December 3 – A SpaceX Falcon 9 rocket launched from California delivered a plethora of payloads.
  • December 4 – An ESA Ariane 5 rocket launched carrying satellites for India and South Korea.
  • December 5 – A SpaceX Falcon 9 rocket launched carrying a resupply flight for the ISS.
  • December 7 – A Chinese Long March 2D rocket launched carrying payloads for Saudi Arabia.
  • December 7 – A Chinese Long March 3B rocket launched carrying the Chang’e 4 mission to the moon.
  • December 16 – A Rocket Lab Electron rocket launched from New Zealand carrying a number of cubesats.

The first stage booster for the Falcon 9 rocket launch on December 5th had to abort its return to launch site landing and ditch in the ocean.

Meanwhile, the Dragon capsule successfully arrived at ISS.

The two Russian cosmonauts currently aboard the ISS conducted a lengthy spacewalk last week to inspect their Soyuz capsule from the outside.

Around the Solar System

NASA’s latest Mars lander, Insight, successfully touched down on the Martian surface last month and has already begun operations. Below is a picture from the lander.

NASA’s Osiris-Rex is now station keeping near asteroid Bennu. The probe has already discovered water-bearing minerals in the asteroid.

Voyager 2 has passed through the heliopause and into interstellar space.

Down to Earth

NASA’s Marshall SpaceFlight Center has a new Director, Jody Singer.

Members of the Jet Propulsion Lab’s media relations team have won an Emmy Award for coverage of the Cassini mission.

Holly Ridings has been named the new chief of the Flight Director office at NASA’s Johnson Space Center.

Veteran NASA astronaut Tim Kopra has left the agency. He flew to space twice, once serving as ISS commander.

SpaceX has announced that Japanese billionaire Yusaku Maezawa has paid to be a passenger on a test flight around the moon.

In Orbit

The following orbital launches have occurred since my last post.

  • September 10 – SpaceX launched a Falcon 9 rocket from Florida carrying a Canadian communications satellite.
  • September 15 – ULA launched a Delta II rocket from California carrying several research payloads.
  • September 16 – India launched a PSLV rocket carrying two Earth-observation satellites.
  • September 19 – China launched a Long March 3B rocket carrying two Beidou navigation satellites.
  • September 22 – Japan launched an H-II rocket carrying an HTV cargo freighter bound for the ISS.
  • September 25 – ESA launched an Ariane 5 rocket carrying two communications satelites.
  • September 29 – China launched a Kuaizhou rocket carrying a small technology demonstration payload.
  • October 8 – SpaceX launched a Falcon 9 rocket from California carrying an Argentinian Earth-observation satellite.

The HTV-7 cargo vehicle was captured and berthed to the ISS several days after it launched.

A Soyuz spacecraft carrying the returning ISS Expedition 56 crew has landed safely in Kazakhstan. Now that Drew Feustel, Ricky Arnold, and Oleg Artemyev are home, the next Soyuz is readying for launch. The Expedition 57 crew of Nick Hague and Aleksey Ovchinin are preparing to launch on Thursday, October 11, which will brin ghte ISS crew back up to 5 people.

The Hubble Space Telescope (HST) has entered safe mode due to a failed gyroscope.

Around the Solar System

Still no news from beleaguered Opportunity rover, on the surface of Mars. It has been 4 months.

And now on the other side of Mars, the Curiosity rover is having issues of its own. JPL engineers are troubleshooting an interruption in science data from the larger rover.

The Japan Aerospace Exploration Agency (JAXA) has successfully deployed 2 small rovers from the Hayabusa 2 spacecraft onto the surface of asteroid Ryugu.

Out There

Astronomers have detected the first evidence of an exomoon (or moon around a planet around another star) using data from the Kepler and Hubble space telescopes. The planetary system is 8,000 lightyears distant.

A bit of fun exoplanet news: astronomers have discovered a planet in orbit around 40 Eridani A, which is the star system of the fictional planet Vulcan from Star Trek.

And lastly in the busy period of astronomy news, a new dwarf planet has been discovered beyond Pluto.

Down to Earth

Elon Musk was busy this week entertaining his fans with tidbits about future SpaceX plans, including the tweet below, as well as this picture on Instagram of a tool for their next larger rocket, the BFR.

NASA’s Planetary Science Division Director, Jim Greene, is now the agency’s new chief scientist.

Check out this music video by Snow Patrol which uses imagery from the ISS and was partially filmed at ESA.

In Orbit

There were three orbital rocket launches since my last post:

On Monday, April 16th, A SpaceX Falcon 9 rocket will launch carrying NASA’s Transiting Exoplanet Survey Satellite (TESS) space telescope.

Around the Solar System

The International Astronautical Union (IAU) has approved official names for features on Pluto’s moon Charon, some named after iconic sci-fi figures such as Stanley Kubrick and Arthur C. Clarke.

Because images of Saturn are just so damn stunning, here’s Saturn’s moon Dione as imaged by the late Cassini spacecraft.

Down to Earth

Virgin Galactic conducted their first glide flight of SpaceShipTwo since last August.

SpaceX’s Falcon Heavy has been attempting to conduct a static fire test ahead of launch, but has scrubbed three days in a row. It has been rescheduled for Monday.

In Orbit

Launches this past week included:

In the case of the SpaceX launch, there have been many reports from reliable journalists over the past week that the classified Zuma payload perhaps did not reach orbit. However, no official statement has yet been forthcoming.

Upcoming launches of interest include a ULA Atlas V from Florida on Jan 19, the next Rocket Lab Electron launch attempt on Jan 20, and SpaceX’s Falcon Heavy test flight (possibly on Jan 25?).

On the ISS, the 13th SpaceX Dragon mission ended successfully with release and splashdown. SpaceX ships are currently retrieving the capsule to return its science samples.
