LAUNCH OF X-37B SPACEPLANE, May 17, 2020, CCAFS, 9:14 am ET


Update, May 17:  Launch was successful at 9:14 am ET.

Update, May 16:  The launch was scrubbed at T-1:40 due to weather.  They will try again tomorrow (May 17) at 9:14 am ET.

Update, May 14:  ULA has announced the launch time as 8:24 am ET.  The weather forecast is only 40 percent favorable, however.  It will be webcast.

Original Entry: The U.S. Space Force (USSF) will launch the Air Force’s X-37B spaceplane on a United Launch Alliance (ULA) Atlas V rocket from Cape Canaveral Air Force Station on May 16, 2020.  Air Force Secretary Barbara Barrett confirmed the launch date during a press conference on May 6.  She did not mention the launch time, but Spaceflightnow.com lists it as between 8:00 and 10:30 am ET.

This is the sixth flight of an X-37B Orbital Test Vehicle (OTV), of which there are two.  Little is known about what these highly secretive missions do, although Barrett said they are trying to declassify some national security space activities, hence her announcement of this launch date and some of the experiments it will carry.

ULA provides this information about the launch, including how to keep up to date, on its website:
