Q&A with Keith Gendreau, principal investigator of the first X-ray space communications experiment (members only)

NASA safety advisors on Thursday lauded hardware milestones on Boeing and SpaceX commercial crew capsules, but said multiple technical issues, including problems with parachutes, must be resolved before the human-rated ships are ready to carry astronauts, adding that both companies continue to pursue schedules that appear to be unachievable.

The milestone comes as a result of the 34th dedicated Starlink launch of the year for SpaceX. Liftoff from pad 40 at Cape Canaveral Space Force Station happened at 8:53 p.m. EDT (0053 UTC).

After several delays earlier this week, SpaceX conducted a hold-down test-firing of a Falcon 9 rocket at Cape Canaveral Friday evening in a key test before launch next week on a resupply mission to the International Space Station.
