Space Test Program 3 Weather Forecast: 80% Chance Favorable

Meteorologists with the U.S. Space Force 45th Weather Squadron predict a 80% chance of favorable weather Tuesday, Dec. 7, for launch of the Department of Defense 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 a.m. EST.

Lifting off from Launch Complex 41 on Cape Canaveral Space Force Station (CCSFS) in Florida, the ULA rocket will take the U.S. Department of Defense’s (DOD) Space Test Program Satellite-6 (STPSat-6) spacecraft, which hosts NASA’s Laser Communications Relay Demonstration (LCRD) and the NASA-U.S. Naval Research Laboratory Ultraviolet Spectro-Coronagraph (UVSC) Pathfinder.

Forecast Details
A ridge of high pressure at the surface will generally dominate central Florida through Wednesday. For primary launch day Tuesday, a frontal boundary stalls over the Florida panhandle, with extensive cloud cover over north Florida and a slight chance for some mid-level clouds to extend further south near the Spaceport. Therefore, the primary concern for launch day is the Thick Cloud Layer Rule. For Wednesday, this front and associated cloud cover lifts further north. With high pressure at the surface, we can expect mostly clear skies, with a very slight chance for a Cumulus Cloud Rule violation Wednesday morning.

Join us here on the blog tomorrow morning for live launch updates – live coverage of the launch is scheduled to air on NASA Television, the agency’s website, and the NASA App beginning at 3:30 a.m. EST.

Space Test Program 3 Launch Update, Now Targeted for Dec. 7

The Dec. 6 launch of a United Launch Alliance (ULA) Atlas V 551 rocket carrying the Department of Defense’s (DOD) Space Test Program 3 (STP-3) mission has been scrubbed. The team repaired the ground storage system but will require additional time to verify the sample integrity of the fuel prior to tanking operations. Launch of the mission – which hosts NASA’s Laser Communications Relay Demonstration (LCRD) and the NASA-U.S. Naval Research Laboratory Ultraviolet Spectro-Coronagraph (UVSC) Pathfinder – is now scheduled for Tuesday, Dec. 7, at 4:04 a.m. EST.

NASA TV live launch coverage will start approximately 35 minutes before launch on Dec. 7, at 3:30 a.m. EST:

Space Test Program 3 Weather Forecast: 90% Favorable for Dec. 6

Meteorologists with the U.S. Space Force 45th Weather Squadron predict a 90% chance of favorable weather Monday, Dec. 6, for launch of the Department of Defense 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 a.m. EST.

Lifting off from Launch Complex 41 on Cape Canaveral Space Force Station (CCSFS) in Florida, the ULA rocket will take the U.S. Department of Defense’s (DOD) Space Test Program Satellite-6 (STPSat-6) spacecraft, which hosts NASA’s Laser Communications Relay Demonstration (LCRD) and the NASA-U.S. Naval Research Laboratory Ultraviolet Spectro-Coronagraph (UVSC) Pathfinder.

Forecast Details
High pressure will retreat into the Atlantic Ocean slightly by Monday, bringing light winds from the south, patchy fog slightly reducing visibility, and a slight chance for isolated low topped showers just off the coast Monday morning. Therefore, the primary concern for launch day is the Cumulus Cloud Rule. For Tuesday, some mid-level clouds ahead of a cold front that will stall out near the Florida panhandle could move over the Spaceport, with an isolated low topped shower still possible just offshore.

Join us here on the blog tomorrow morning for live launch updates – live coverage of the launch is scheduled to air on NASA Television, the agency’s website, and the NASA App beginning at 3:30 a.m. EST.

Space Test Program 3 Weather Forecast: Remains 90% Favorable

Meteorologists with the U.S. Space Force 45th Weather Squadron predict a 90% chance of favorable weather Sunday, Dec. 5, for launch of the Department of Defense 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 a.m. EST.

Lifting off from Launch Complex 41 on Cape Canaveral Space Force Station (CCSFS) in Florida, the ULA rocket will take the U.S. Department of Defense’s (DOD) Space Test Program Satellite-6 (STPSat-6) spacecraft, which hosts NASA’s Laser Communications Relay Demonstration (LCRD) and the NASA-U.S. Naval Research Laboratory Ultraviolet Spectro-Coronagraph (UVSC) Pathfinder.

Forecast Details
High pressure will be in place over central Florida through Sunday morning when it retreats into the Atlantic Ocean slightly by Monday, bringing light winds Sunday coming from the south on Monday, and a slight chance for isolated low topped showers near the coast on Monday. Therefore, there is minimal concern for the Cumulus Cloud Rule on Sunday, and an increased concern for the same on Monday as isolated showers near the coast.

Primary concern: Cumulus Cloud Rule

Space Test Program 3 Weather Forecast: 90% Chance Favorable

Lifting off from Launch Complex 41 on Cape Canaveral Space Force Station in Florida, a United Launch Alliance Atlas V rocket will take the Department of Defense Space Test Program Satellite-6 (STPSat-6) spacecraft, which hosts NASA’s Laser Communications Relay Demonstration (LCRD) and the NASA-U.S. Naval Research Laboratory Ultraviolet Spectro-Coronagraph (UVSC) Pathfinder.

Meteorologists with the U.S. Space Force 45th Weather Squadron predict a 90% chance of favorable weather Sunday, Dec. 5, for 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 a.m. EST.

Lifting off from Launch Complex 41 on Cape Canaveral Space Force Station (CCSFS) in Florida, the ULA rocket will take the DOD’s Space Test Program Satellite-6 (STPSat-6) spacecraft, which hosts NASA’s Laser Communications Relay Demonstration (LCRD) and the NASA-U.S. Naval Research Laboratory Ultraviolet Spectro-Coronagraph (UVSC) Pathfinder.

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

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

Forecast Details
High pressure will build at the surface over central Florida through Saturday. This will keep the launch area dry all day Friday with light winds and near average temperatures. The surface high retreats into the Atlantic Ocean slightly Sunday into Monday, bringing light winds Sunday coming from the south on Monday, and a slight chance for isolated low topped showers near the coast, especially on Monday. Therefore, the primary concern for launch day is the cumulus cloud rule.

Launch Coverage: Dec. 5
Live coverage and countdown commentary of the launch will begin at 3:30 a.m. EST and air on NASA Television and the agency’s website, as well as YouTube, Twitter, Facebook, LinkedIn, Twitch, Daily Motion, Theta.TV and the NASA App.

NASA invites the public to register to virtually attend the launch and receive mission updates and activities via email. NASA’s virtual guest program for LCRD includes curated launch resources, notifications about related opportunities, and a virtual guest passport stamp.

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

NASA and United Launch Alliance currently are reviewing the launch date for the Landsat 9 spacecraft scheduled to launch from Vandenberg Space Force Base in California. Current pandemic demands for medical liquid oxygen have impacted the delivery of the needed liquid nitrogen supply to Vandenberg by the Defense Logistics Agency (DLA) and its supplier Airgas. Airgas converts the liquid nitrogen to gaseous nitrogen needed for launch vehicle testing and countdown sequences. DLA and Airgas now have implemented efforts to increase the supply of liquid nitrogen to Vandenberg. The Landsat 9 launch now is expected no earlier than Thursday, Sept. 23, 2021.

Landsat 9 is a joint NASA and U.S. Geological Survey (USGS) mission that continues the legacy of monitoring Earth’s land and coastal regions, which began with the first Landsat in 1972. The mission will launch on a United Launch Alliance Atlas V rocket from Space Launch Complex 3 at Vandenberg.
