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

NASA successfully completed its latest underwater NEEMO mission off the coast of Florida. A crew of astronauts and engineers spent several days in an underwater base testing techniques, gear, and technology for spaceflight. This was the 22nd expedition to the underwater facility.

The Canadian Space Agency announced the selection of their two latest Astronaut Candidates. Jennifer Sidley is a 28-year-old PhD and professor at the University of Cambridge. Joshua Kutryk is a 35-year-old fighter pilot and test pilot with several master’s degrees.

The President of the United States signed an executive order establishing a National Space Council, to guide all of the nation’s endeavours related to spaceflight.

In Orbit

There were five rocket launches since my last post:

Yes, SpaceX had a 48 hour turnaround between two launches, to reach 9 launches on the year. Both first stages were recovered.

In a non-orbital launch, NASA launched an experiment sounding rocket from Virginia’s Wallops Island.

A large satellite in geostationary orbit appears to have broken apart, causing concerns about orbital debris in one of the most important Earth orbits.

Around the Solar System

A recent survey of outer solar system bodies, which found several new distant objects, casts doubt on the hypothesized existence of “Planet 9”. However, the lead researchers of the Planet 9 theory have done their own analysis of the new data, and claim that the data can fit the model. The hunt for Planet 9 continues.

The Curiosity rover is still climbing up Mount Sharp in the center of Gale Crater on Mars. Recently, the MRO spacecraft captured this image of the rover from orbit.
