Q&A with Andrew Driesman, project manager for Parker Solar Probe (members only)

SpaceX is still working on a new, safer helium tank design needed for launches with astronauts, and the debut of the company’s upgraded Falcon 9 Block 5 rocket earlier this month did not count as one of seven successful missions in “crew configuration” NASA says it requires before putting astronauts aboard the vehicle, officials said Thursday.

SpaceX said Tuesday it won’t perform a final countdown dress rehearsal this week for the giant new Starship launch vehicle, and could send the rocket — standing nearly 40 stories tall on its Texas launch pad — on an around-the-world test flight as soon as next week.

A Japanese HTV cargo freighter is set for launch Tuesday (U.S. time) aboard a powerful H-2B rocket, ferrying six new lithium-ion batteries, a Sony-developed laser communications terminal, fresh water and other equipment to the International Space Station.
