After the launch of a Progress resupply craft to the ISS was scrubbed last Sunday, it was launch successful on Tuesday and docked to the ISS two days later.

Other than the Progress, launched on a Soyuz rocket from Baikonaur, the only other launch last week was a Chinese Long March 3B rocket carrying two global navigation satellites.

The Opportunity rover has now spent more than 5,000 martian days (or “sols”) on Mars. To commemorate the occasion, the JPL rover team commanded Opportunity to take a “self-portrait” mosaic using the cameras on the end of its robotic arm. This is the first time this has been done with Opportunity.

New Horizons has broken the record held by Voyager’s famous Pale Blue Dot image for farthest images taken from Earth. The probe is on its way to an encounter with 2014 MU69 next January. While it is cruising through the Kuiper Belt, it took advantage of its “near” pass to two other objects and took some low resolution images of 2012 HZ84 and 2021 HE85.

Another government shutdown on Thursday night nearly impacted US federal government operations again (including NASA) but was ended in the middle of the night with a budget deal, before facilities could open for work on Friday.

Sierra Nevada Corporation has received their official launch window from NASA for their first uncrewed resupply mission to the ISS, using their DreamChaser space plane.

A SpaceX booster that survived an ocean crash-landing from the GovSat-1 launch on January 31, was demolished at sea as it as deemed a safety hazard.

The only rocket launch since my last post was a big one: the demo flight of the Falcon Heavy. The rocket launched successfully during its first launch window last Tuesday, to the delight of crowds on the ground in Florida and millions of space fans who watched the livestream online. The next Falcon Heavy is scheduled tentatively a few months out, and will carry more official payloads.

There were two rocket launches last week:

The Ariane 5 rocket had some kind of anomaly with the upper stage and placed the payloads in the wrong orbit.

ISS astronauts Mark Vande Hei and Scott Tingle completed a spacewalk last Tuesday to service to Canadarm-2. Unfortunately, an issue discovered after the spacewalk has caused a change of plans, and a second excusion planned for this coming Monday will be used to enact some repairs.

Some news from Mars:

  • Researchers hope to observe a global dust storm on Mars in the near future to validate a theory that dust storms contribute to the loss of the planet’s atmosphere.
  • Data from NASA’s Mars Reconnaissance Orbiter (MRO) has found potential ice sheets at mid-latitudes on the red planet.

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.. The reports outline a few issues that the commercial providers – SpaceX and Boeing – both need to work through before their rockets and capsules can be certified to flight NASA astronauts to the ISS. 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.

Three rocket launches since my last post. All of them occurred today, October 9th:

  • China launched a Long March 2D rocket carrying a Venezuelan satellite.
  • SpaceX launched a Falcon 9 rocket carrying 10 new communication satellites for Iridium.
  • Japan launched an H-2A rocket carrying a native navigation satellite.

Things have been quite busy up on the ISS. Astronauts Mark Vande Hei and Randy Bresnik executed the first of a series of spacewalks last week to maintain the station’s robotic arm. They will go out again tomorrow, October 10th, to continue the work. Here are a few pictures from last week’s EVA:

NASA has announced plans to keep the Bigelow Expandable Activity Module (BEAM) on the ISS for longer than planned and use it as a logistics module.

A recent study of “Tabby’s Star” using NASA’s orbiting observatories Spitzer and Swift has a new theory for the unexplained dips in brightness: dust. The new hypothesis is compelling because the telescopes detected differences in the dimming at different wavelengths, which implies something transparent like dust.

I’m back from my own personal August recess and catching up on almost a month of space news. Here’s your headline dump for August 14 to September 9! A lot has happened

Down to Earth

The Trump Administration has named Oklahoma Congressman Jim Bridenstine as their nominee for NASA administrator.

The Chinese and European astronauts conducted a joint survival training exercise off the coast of China.

Sierra Nevada Corporation conducted a “captive carry” flight of their Dream Chaser spaceplane.

Last week an ESA Ariane 5 rocket had a pad abort. The agency is still investigating.

The Dragon capsule launched two days earlier docked with the ISS on August 16th.

The day after the cargo. arrival, cosmonauts Fyodor Yurchikhin and Sergey Ryazanskiy conducted a successful spacewalk to do space station maintenance as well as some small satellites deployments.

Then on September 3rd a Soyuz returned to Earth, safely carrying Jack Fischer, Peggy Whitson, and Fyodor Yurchikhin to the steppes of Kazakhstan. Both Yurchikhin and Whitson now have accumulated over 600 days in space.

Meanwhile on the ground, a dedicated team of flight controllers was riding out Hurricane Harvey in Houston’s Mission Control Center to ensure the successful undocking and return of the crew.

Speaking of hurricanes, the ISS crew has taken some incredible imagery of Irma has it makes its way across the Caribbean and now Florida.

Lots of launches while I was out. Here’s a worldwide rundown:

On July 2, the Chinese space agency attempted to launch a communications satellite on their heavy lift Long March 5 rocket. Unfortunately, the second stage failed and the payload did not make it to orbit.

On July 5, SpaceX launched a Falcon 9 rocket carrying a commercial communications satellite for Intelsat. The satellite was delivered to geosynchronous orbit. Due to the high performance requirements of the mission, the first stage was disposable, rather than being recovered. This was their 10th launch of the year (the most of any year for SpaceX).

Meanwhile, up on the ISS on July 3rd, the Expedition 52 astronauts unberthed and released the visiting SpaceX Dragon capsule, which splashed down and was recovered that same day.
