Live coverage: Vega rocket launches with LISA Pathfinder

After assessing any damage to the spaceport caused by Hurricane Dorian as it narrowly missed Florida’s east coast, NASA says the Kennedy Space Center will reopen for normal operations Friday. Teams rolled the Space Launch System’s mobile launch platform from pad 39B back into the cavernous Vehicle Assembly Building last week for safekeeping during the storm.

Technicians working in the jungle of French Guiana have installed four new European Galileo navigation satellites on top of their Ariane 5 launcher, and filled the rocket’s upper stage with storable liquid propellants for liftoff Tuesday.

Engineers working on the James Webb Space Telescope, which had its launch delayed to 2020 earlier this year, recently discovered another problem during testing at the observatory’s prime contractor Northrop Grumman in Southern California.
