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.

Over the past two weeks there have been only two orbital rocket launches. The first was a Chinese Long March 2D rocket carrying an Earth-observing satellite. The second was a Soyuz rocket launched from Kazakhstan carrying 3 crew members on their way to the International Space Station.

Oleg Artemyev, Drew Feustel, and Ricky Arnold docked to the ISS successfully this past Friday, two days after launch. They join Anton Shkaplerov, Norishige Kanai, and Scott Tingle for the ongoing Expedition 55 mission.

Swarm Technologies launched four very small satellites in January without license from the FCC. In fact, the FCC had specifically asked them not to launch because they were too small to track. Now Swarm may not be able to receive future licenses.

Astronomers using the Hubble Space Telescope and Spitzer Space Telescope have discovered a distant water-rich planet, Wasp-39b. The planet is not Earth-like – it is a large planet like Saturn.

The only launch of the week was a SpaceX Falcon 9 rocket launched from Vandenberg in Californial. The rocket carried three satellites – a payload for the Spanish military and two technology demonstration satellites for SpaceX. The company also tried to “catch” one of the rocket’s discarded payload fairings at sea, but missed slightly. Here is a photo from Instagram of the fairing floating near the SpaceX’s recovery ship.

A Soyuz carrying three space station residents will undock from the ISS on Tuesday morning and return to Earth. Recovery crews are already getting ready out in Kazakhstan.

NASA’s Mars Reconnaissance Orbiter had a bit of a scare last week, entering safe mode for about 3 days after a battery malfunction. MRO came out of safe mode on the 23rd and NASA reported that it was being returned to nominal service. MRO is a key asset, as it relays all communications from the two rovers on the surface.

Meanwhile, down on the surface, Opportunity continues to trundle along in Endeavour crater. JPL even announced some new observations this past week.

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.
