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.
