The ULA Atlas V rocket was moved into the company’s Vertical Integration Facility at Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida, which starts the preparations for its stacking operations ahead of NASA’s Boeing Crew Flight Test.

The rocket’s main stage was transferred from the nearby Advanced Spaceflight Operations Center to the integration facility Wednesday, Feb. 21, where it will await integration with the rocket’s upper Centaur stage and Starliner. The spacecraft will carry NASA astronauts Suni Williams and Butch Wilmore to the orbiting laboratory for a short stay of about one to two weeks before returning to a landing site in the southwest United States.

The mission will test the end-to-end capabilities of the Starliner system, including launch, docking, and a return to Earth. After successful completion of the mission, NASA will begin the final process of certifying Starliner and its systems for crewed rotation missions to the space station.

NASA and Boeing are targeting no earlier than late April for launch. Starliner completed two uncrewed flight tests, including Orbital Flight Test-2, which docked to the space station on May 21, 2022, and provided valuable data leading up to its first crewed flight.

Details about the mission and NASA’s Commercial Crew Program can be found by following the commercial crew blog, X, and Facebook.

NASA’s LCRD Launches Aboard Space Test Program 3

United Launch Alliance’s Atlas V 551 rocket successfully launched from Launch Complex 41 on Cape Canaveral Space Force Station in Florida on Dec. 7, at 5:19 a.m. EST for the Department of Defense’s (DOD) Space Test Program 3 (STP-3) mission. Two satellites were on board, including the Space Test Program Satellite-6 (STPSat-6) spacecraft, which carried two NASA payloads that have been successfully deployed:

The Laser Communications Relay Demonstration (LCRD), will be NASA’s first end-to-end laser relay system, sending and receiving data over invisible infrared lasers at a rate of approximately 1.2 gigabits per second from geosynchronous orbit to Earth. With data rates 10 to 100 times higher than traditional radio frequency systems, laser communications systems will provide future missions with extraordinary data capabilities.

The mission will operate for at least two years. Engineers will beam data between LCRD and optical ground stations located in Table Mountain, California, and Haleakalā, Hawaii, once LCRD is positioned more than 22,000 miles above Earth. Experiments will refine the transmission process, study different operational scenarios, and perfect tracking systems. The information and data are essential to readying a laser communications system for an operational mission because engineers cannot replicate the same conditions with ground tests.

UVSC Pathfinder — short for Ultraviolet Spectro-Coronagraph Pathfinder — begins its mission to peer at the lowest regions of the Sun’s outer atmosphere, or corona, where solar energetic particles, the Sun’s most dangerous form of radiation, are thought to originate. A joint NASA-U.S. Naval Research Laboratory experiment, UVSC Pathfinder becomes the latest addition to NASA’s fleet of heliophysics observatories, which study a vast, interconnected system from the Sun to the space surrounding Earth and other planets, and to the farthest limits of the Sun’s constantly flowing stream of solar wind.

NASA’s Laser Communications Relay Demonstration Deploys

Rendering of LCRD Spacecraft
The Laser Communications Relay Demonstration payload is attached to the LCRD Support Assembly Flight (LSAF), which can be seen in this image. The LSAF serves as the backbone for the LCRD components. Attached to the LSAF are the two optical modules, which generate the infrared lasers that transmit data to and from Earth. A star tracker is also attached here. These components are visible on the left side of this image. Other LCRD components, such as the modems that encode data into laser signals, are attached to the back of the LSAF.

NASA’s payloads aboard STP-3, the Laser Communications Relay Demonstration (LCRD) and UVSC Pathfinder, have successfully deployed. The Centaur second stage released the U.S. Department of Defense’s Space Test Program Satellite-6 (STPSat-6) spacecraft, which hosts the payloads, into geosynchronous orbit. After coasting for another 40 minutes, Centaur will release the Space Force’s additional satellite, completing the longest Atlas mission in its more than 60-year history.

LCRD will use laser communications systems to transmit data from space to Earth and help NASA update how astronauts communicate to and from space. LCRD is led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Partners include NASA’s Jet Propulsion Laboratory in Southern California and the MIT Lincoln Laboratory. LCRD is funded through NASA’s Technology Demonstration Missions program, part of the Space Technology Mission Directorate, and the Space Communications and Navigation (SCaN) program at NASA Headquarters.

UVSC Pathfinder — short for Ultraviolet Spectro-Coronagraph Pathfinder — will peer at the lowest regions of the Sun’s outer atmosphere, or corona. The mission 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.

LCRD Is On Its Way!

Rocket launch.
In this twenty-second exposure, a United Launch Alliance Atlas V rocket launches on the Department of Defense’s Space Test Program 3 (STP-3) mission from Space Launch Complex 41 at Cape Canaveral Space Force Station, Tuesday, Dec. 7, 2021, from NASA’s Kennedy Space Center in Florida.

The Laser Communications Relay Demonstration (LCRD) mission has successfully launched, completed two Centaur engine burns, and is on its way! The Department of Defense’s (DOD) Space Test Program 3 (STP-3) mission sent two satellites including the Space Test Program Satellite-6 (STPSat-6) spacecraft, which hosted two NASA payloads –  LCRD and the NASA-U.S. Naval Research Laboratory Ultraviolet Spectro-Coronagraph (UVSC) Pathfinder – to space. STPSat-6 is scheduled to separate from Centaur into geosynchronous orbit in about 6 hours.

The first main engine cutoff, or MECO-1, is confirmed for the United Launch Alliance (ULA) Atlas V rocket’s  Centaur upper stage. It will coast in this preliminary Earth orbit for the next hour before the second burn begins.

The Atlas launched the Department of Defense’s (DOD) Space Test Program 3 (STP-3), which hosts NASA’s Laser Communications Relay Demonstration (LCRD) and the NASA-U.S. Naval Research Laboratory Ultraviolet Spectro-Coronagraph (UVSC) Pathfinder.

The United Launch Alliance (ULA) Atlas V 551 rocket has jettisoned its five solid rocket boosters and is approaching payload fairing jettison.

At this point in its ascent, the Atlas V is burning propellant at a rate of 2,000 pounds per second, traveling more than 7,500 miles per hour and located 64 miles in altitude and 150 miles down range.

Main engine cutoff will occur about a minute after booster jettison, followed shortly by Atlas Centaur separation.
