There were only two orbital launches in the past week:

  • April 2 – SpaceX launched a Falcon 9 rocket carrying a Dragon resupply capsule to the ISS.
  • April 6 – ESA launched an Ariane 5 rocket carrying a pair of communications satellites.

The Dragon spacecraft arrived at the ISS two days later where the station astronauts grappled it with the robotic arm. A busy month of operations now begins as the astronauts unpack the Dragon and begin new science experiments.

The Indian space agency (ISRO) lost contact with a communications satellite they launched last week.

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.

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.
