Live coverage: Ariane 5 blasts off with two Intelsat satellites

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.

On the eve of launching its first ViaSat 3 internet satellite on a SpaceX rocket, Viasat says it has moved the launch of an identical spacecraft off of Europe’s long-delayed Ariane 6 rocket, and is considering bids from other rocket companies.

SpaceX’s next launch with a European-built communications satellite has been delayed to no earlier than March 28 to study a problem with a helium pressurization system on the Falcon 9 rocket, officials said Tuesday.
