The first Boeing Starliner test at the end of 2019 was unsuccessful. Synchronization of mission clocks went astray, confused the capsule and led it to needlessly burn too much fuel for unnecessary maneuvers.

While there was too little fuel reserve left to safely dock to the ISS, it was possible to check out other parts of the mission on orbit and land the capsule.

It turns out Boeing found more software glitches that could have resulted in loss of craft during reentry.

The second test flight launches on a ULA Atlas V from Space Launch Complex 41, Canaveral Space Force Station, Florida.

Payload mass is 13200 kg.

Goal of this mission is to fly to the ISS, dock and return to earth.

Starliner will only carry limited amounts of cargo to and from orbit and will stay attached to station for 5 days.


The 45th Weather Squadron predicts weather conditions on launch day at 60% go. Main concerns: thick clouds, lightning and cumulus clouds.
