Russia will stop building the Proton rocket.

The launch of the James Webb Space Telescope (JWST) has been officially delayed to 2021.

Virgin Orbit has been granted an FAA launch license for its first launch from California.

In Orbit

There were two orbital rocket launches during the last week. On June 27th, China launched a Long March 2C rocket carrying two satellites into orbit. On July 29th, SpaceX launched a Falcon 9 rocket from Florida, carrying a Dragon cargo craft scheduled for arrival at ISS on Monday morning.

Meanwhile, Rocket Lab was not able to launch last week and has delayed their first commercial flight.

Around the Solar System

Out at Mars, there were no updates on the dust storm of the status of the dormant rover Opportunity.

After weeks of a slow approach, Japan’s probe Hayabusa-2 has arrived at asteroid Ryugu, with gorgeous views of the never before explored rock.

Astronomers have new evidence that the interstellar visitor ‘Omuamua was actually a comet, not an asteroid.

Down to Earth

The United Arab Emirates (UAE) will take advantage on an open seat in an upcoming Soyuz flight to ISS and fly their first homegrown astronaut into orbit.

The US Air Force has awarded a contract to SpaceX to launch a DOD satellite on a Falcon Heavy in 2020.

Last week the President of the United States signed Space Policy Directive 3, which establishes a formal National Space Traffic Management Policy.

In Orbit

There were no orbital rocket launches or major mission events at the International Space Station last week. However, the NanoRacks Remove Debris (or RemDeb) satellite was deployed from the ISS. This satellite will demonstrate techniques for reducing orbital debris in Low Earth Orbit (LEO).

The ISS crew continues to be busy with maintenance and science as always. Here’s a selection of some of their most interesting photos posted to Twitter last week.

In upcoming launches, Rocket Lab will attempt to launch their next Electron rocket on Tuesday (New Zealand time) and SpaceX will launch their next Dragon resupply to ISS next Friday.

Around the Solar System

Japan’s Hayabusa-2 continues to get closer to its destination, asteroid Ryugu. Some more detailed images of the unexplored rock were downlinked last week.

NASA’s Dawn spacecraft has been slowly lowering its orbit around asteroid Ceres to get new unprecedented views of the dwarf planet.

The large dust storm on the surface of Mars continues, with no contact from the rover Opportunity. Rover Curiosity continues to operate in Gale Crater, sending back this recent dusty “selfie.”

Data from Japan’s Akatsuki spacecraft, which orbits Venus, has returned some interesting results about the variability of the planet’s day-night cycle.

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.
