Space Test Program 3 Weather Forecast: 90% favorable chance

Status report of: Kennedy Space Center
Posted: Friday December 3 2021

Meteorologists from the 45th Weather Squadron of the US Space Force predict a 90% chance of favorable weather conditions on Sunday, December 5 for the launch of the Department of Defense (DOD) Space Test Program 3 (STP-3) mission on United Launch Alliance (ULA) Atlas V 551 rocket. The two-hour launch window opens at 4:04 am EST.

Taking off from Launch Complex 41 on Cape Canaveral Space Force Station (CCSFS) in Florida, the ULA rocket will carry DOD’s space test program spacecraft, satellite-6 (STPSat-6), which hosts The NASA Laser communication relay demonstration (LCRD) and the NASA-US Naval Research Laboratory Pathfinder Ultraviolet Spectro-Coronagraph (UVSC).

The LCRD is about the size of a king-size mattress and seeks to make operational laser communications a reality. As space missions generate and collect more data, higher bandwidth communication technology is needed to bring data home, and laser communication systems offer higher bandwidth in a smaller package that uses less power. The LCRD will send and receive data via infrared lasers at approximately 1.2 gigabits per second from geosynchronous orbit to Earth.

UVSC Pathfinder is a joint NASA-US Naval Research Laboratory experiment that studies the origins of solar energetic particles, the most dangerous form of radiation from the Sun.

Forecast details
The high pressure will build up on the surface over central Florida through Saturday. This will keep the launch pad dry all day Friday with light winds and near average temperatures. The surface high recedes slightly into the Atlantic Ocean from Sunday to Monday, bringing light winds on Sunday from the south on Monday, and a slight possibility of isolated low-level showers near the coast, particularly Monday. Therefore, the main concern for the day of the launch is the cumulus cloud rule.

Launch Coverage: December 5
Live coverage and commentary of the launch countdown will begin at 3:30 a.m. EST and will air on NASA Television and the Agency. website, as good as Youtube, Twitter, Facebook, LinkedIn, Tic, Daily movement, Theta.TV and the NASA app.

NASA invites the public to Register now virtually attend the launch and receive mission updates and activities via email. that of NASA virtual guest program for LCRD includes organized launch resources, notifications about related opportunities, and a virtual guest passport stamp.

Teachers and students can explore the LCRD STEM Toolkit. The kit includes five activity sheets, each designed for a target level, a model of STPSat-6 that students and teachers can 3D print, a preview of LCRD, and several other printable items. Many of the Toolkit resources are also available in Spanish.
