Teams working in Northrop Grumman’s spacecraft factory in Southern California have connected the spacecraft and science modules of the James Webb Space Telescope for the first time, a major milestone as engineers prepare to verify a fix to tears in the observatory’s sunshield, and begin launch vibration and acoustic testing in the coming months.

On the eve of its blazing entry into the Martian atmosphere, NASA’s InSight spacecraft briefly pulsed its control jets Sunday to target a safe, flat landing zone near the planet’s equator — the last in a series of trajectory correction maneuvers since the mission’s launch in May.
