Live coverage: Vega rocket launches with LISA Pathfinder

United Launch Alliance fired an Atlas 5 rocket into space from Cape Canaveral at 9:14 a.m. EDT (1314 GMT) Sunday with the U.S. Air Force’s X-37B spaceplane, an automated reusable mini-space shuttle designed to host experiments for years in orbit, then return to Earth and land on a runway. A launch attempt Saturday was scrubbed by bad weather.

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.
