Down to Earth

In late July, Virgin Galactic conducted a third powered test flight of their new SpaceShipTwo spaceplane.

In a ceremony at Johnson Space Center, NASA announced the names of the astronauts who will fly the first flights of the Boeing Starliner and SpaceX Dragon, the first crewed missions from US soil since 2011.

SpaceX installed a shiny new crew access arm to launch complex 39A at Kennedy Space Center.

Russia has selected a new class of 8 cosmonauts.

United States Vice President Mike Pence visited the Johnson Space Center and gave a speech on future plans for exploration.

Rocket Lab’s next Electron launch has been delayed further.

In Orbit

Operations at the ISS over the past month have included two visiting vehicle departures and one spacewalk. On August 3rd, the latest SpaceX Dragon cargo vehicle undocked from ISS and splashed down in the Pacific. On August 22nd, a Russian unmanned Progress freighter undocked from the ISS. On august 15th, two Russian cosmonauts, Oleg Artemyev and Sergey Propokyev, conducted a lengthy spacewalk to complete maintenance and science tasks.

There were 8 orbital rocket launches since my last post on July 23rd:

  • July 25 – ESA Ariane 5 rocket launched carrying Galileo navigation satellites.
  • July 25 – SpaceX Falcon 9 rocket launched from California carrying communications satellites for Iridium.
  • July 29 – Chinese Long March 3B rocket launched carrying BeiDou navigation satellites.
  • July 31 – Chinese Long March 4B rocket launched carrying an Earth-observing satellite.
  • August 7 – SpaceX Falcon 9 rocket launched from Florida carrying an Indonesian communications satellite.
  • August 12 – ULA Delta IV Heavy rocket launched from Florida carrying NASA’s Parker Solar Probe.
  • August 22 – ESA Vega rocket launched carrying an Earth-observing mission.
  • August 24 – Chinese Long March 3B rocket launched carrying more BeiDou navigation satellites.

The Martian dust storm is waning but NASA mission teams have yet to hear from the Opportunity rover.

Down to Earth

NASA announced a new class of 6 flight directors for human spaceflight at Johnson Space Center.

The Indian Space Research Organization (ISRO) performed a pad abort test of their launch escape tower for future crewed spaceflights.

Launch towers at Launch Complex 17 at Cape Canaveral were demolished last week. These launch towers were built for the now retired Delta II rocket. Instead, Moon Express will use the site.

Launch industry newcomer Rocket Lab plans to open a second launch site somewhere in the USA.

James Morhard has been nominated to the open position of NASA deputy administrator.

Astronaut Dan Burbank has retired from NASA.

In Orbit

NASA’s Kepler Space Telescope has entered a hibernation mode as it nears the end of its long mission.

There were three orbital rocket launches since my last post on July 1st:

Operations have been busy on the International Space Station. The Dragon resupply ship that launched at the end of June arrived at ISS on July 2nd. Then the above mentioned Progress resupply arrived.

On Sunday morning, the latest Cygnus cargo spacecraft departed the ISS packed full of trash. Before it left, it performed a demonstration maneuver to reboost the ISS.

Upcoming notable launches include a SpaceX launch from Florida on July 20th and a SpaceX launch from California on July 22nd. Still no firm launch date on the rescheduled Rocket Lab launch.

Around the Solar System

Still no update from NASA’s Opportunity rover, which has been socked in by a dust storm on Mars.

Down to Earth

Peggy Whitson, the American astronaut with the most day’s in space, has retired from NASA.

Orbital ATK is no officially a division of Northrop Grumman.

An interesting Pew Research Center poll was getting some media coverage last week, after it showed that the American public’s priorities for NASA do not line up with its official priorities (at least when you measure “priorities” by funding levels).

Check out the trailer for the upcoming film First Man.

The new NASA Johnson Space Center director, Mark Geyer, now has a twitter account.

The soccer ball used to kickoff the 2018 FIFA World Cup was previously flown to the ISS.

In Orbit

There were four orbital rocket launches since my last post on June 5th:

  • June 5 – China launched a Long March 3A rocket carrying a weather satellite.
  • June 6 – Russia launched a Soyuz rocket carrying three new crew members to the ISS.
  • June 12 – Japan launched an HII-A rocket carrying a reconnaissance satellite.
  • June 16 – Russian launched a Soyuz rocket carrying a GLONASS navigation satellite.

In upcoming launches, Rocket Lab will launch its first commercial flight from New Zealand on June 23rd.

The Soyuz crew arrived at the ISS a couple of days after launch, bringing the onboard crew to six withSergey Prokopyev, Serena Auñón-Chancellor, and Alex Gerst now onboard.

Astronauts Drew Feustel and Ricky Arnold completed a nearly 7-hour spacewalk at the ISS last Thursday, in order to complete maintenance activities and install new cameras.

Around the Solar System

A major dust storm on Mars has caused NASA to lose contact with the solar-powered Mars rover Opportunity. The rover is in low power mode waiting out the storm. Mission controllers are waiting for sufficient battery charge to allow the rover to restore communications.

Fortunately, the nuclear powered rover Curiosity can keep on roaming through the dust storm. It captured this image of the hazy sky from Gale Crater.

Scientists with the Curiosity mission published two new papers detailing discoveries related to season methane concentrations in the atmosphere and ancient organic molecules in rock samples.

An extension to NASA’s Juno mission, currently in orbit of Jupiter, has been approved.

Japan’s Hayabusa-2 spacecraft is now close enough to asteroid Ryugu that it has been able to image the small rock.

Out There

Astronomers have made observation of a “tidal event” in which a star is seen falling into a supermassive black hole in a distant galaxy.
