Watch the Falcon 9 launch from pad 39A

A Cygnus supply ship built by Northrop Grumman departed the International Space Station Monday, beginning an extended mission in orbit to deploy a pair of CubeSats and perform a NASA-sponsored fire experiment.

The Starlink 6-88 added 29 broadband internet satellites to the constellation of more than 9,300 in low Earth orbit. Liftoff from pad 40 at Cape Canaveral Space Force Station happened at 1:48 a.m. EST (0648 UTC).

Armed with a knife, scissors and other cutting tools, cosmonauts Oleg Kononenko and Sergey Prokopyev went outside the International Space Station on Dec. 11 to slice into the thermal insulation of a Soyuz spaceship and inspect the site of a repaired air leak that briefly caused a minor drop in air pressure in the research outpost earlier this year.
