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

Catching a break from nearby thunderstorms, a SpaceX Falcon 9 rocket soared through mostly cloudy skies into space Saturday on the 100th launch from historic pad 39A in Florida, sending a fresh batch of supplies and experiments to the International Space Station.

SpaceX test-fired its next Falcon 9 rocket Friday ahead of a planned launch Monday from Cape Canaveral with 60 more Starlink Internet satellites, days after an international group sounded another warning about the effects of large satellite fleets on astronomy.

The James Webb Space Telescope is at risk of another launch delay beyond the mission’s current target launch date in March 2021, the Government Accountability Office said this week.
