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).

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.

A number of orbital rocket launches since my last post on May 20th:

Notable rocket launches coming up include a Soyuz rocket with 3 astronauts launching form Kazakhstan on Wednesday morning.

The Cygnus spacecraft was successfully captured by the ISS robotic arm on May 24 and installed on a docking port, delivering tons of supplies.

Last Wednesday, Drew Feustel and Ricky Arnold completed a planned 6-hour and 31-minute spacewalk aboard the International Space Station.

The only orbital rocket launch since my last post on May 15th was a Chinese Long March 4C rocket carrying the Queqiao satellite. Queqiao will be a a communications relay satellite for the upcoming Chang’e 4 lunar rover mission.

China also launched a notable suborbital rocket this past week. A private Chinese company OneSpace Technology, performed the first launch of their OS-X suborbital rocket.

Next week there are some interesting launches planned. On Monday, May 21, Orbital ATK will launch a Cygnus on its way to the ISS from Wallops Island Virginia. On Tuesday, May 22, SpaceX will launch a Falcon 9 rocket form Vandenberg in California.

Some recent crew assignment changes for the ISS have been receiving a lot of press, including the replacement of Jeanette Epps with Serena Aunon-Chancellor for a launch this summer. NASA has not provided specific details on the reason for the change.

As of Saturday morning, the US federal government has no official funding and must shutdown many services. This shutdown affects NASA and its field centers. The specific impacts to NASA operations will become more clear if the shutdown extends into the work week on Monday morning. In the meantime, NASA will press forward with the ISS spacewalk on Tuesday.

There was a lot of talk last week about an update on the schedule for NASA’s Commercial Crew Program, which has slipped according to a report from the Aerospace Safety Advisory Panel (ASAP). There was also a Government Accountability Office (GAO) report on the same topic..

Both companies answered questions at a congressional hearing following the report on Wednesday.

SpaceX still has not conducted a static fire of the Falcon Heavy rocket on Pad 39A. They are expected to try again this coming week with a potential launch before the end of the month.
