Q&A with Marc Rayman, chief engineer on NASA’s Dawn mission (members only)

Teams at Stennis Space Center in Mississippi removed the core of NASA’s first Space Launch System heavy-lift rocket from a test stand earlier this week for loading onto a barge to carry it to Kennedy Space Center in Florida, where the rocket stage is due to arrive by the end of the month to start final preparations for a test flight around the Moon.

Northrop Grumman engineers were able to create a new burn plan for the spacecraft after it missed two attempts to perform its “targeted altitude burn.” Capture using the robotic Canadarm2 happened at 3:11 a.m. EDT (0711 UTC) on Tuesday, Aug. 6.

Decisions on the future of a joint robotic mission between NASA and the European Space Agency to demonstrate the ability to deflect an asteroid on a collision course with Earth have been put off until later this year after European governments declined to fully fund their part of the project in December.
