The 59.7-meter rocket is expected to be launched in its heaviest configuration: the 551. This means that the rocket is powered by five solid rocket motors, a single-engine Centaur upper stage, and its payload is folded away. 16.4 ft (5 m) gift.
This version of Atlas V has launched a number of high-profile payloads over the years, including Curiosity and determination Mars rovers.
The rocket made its way to the launch pad on Friday, December 3, traveling 1,800 feet (550 meters) between ULA’s vertical integration facility and the ramp.
Inside the payload stream are two satellites, each containing a set of prototypes and technology experiments that will be tested in orbit.
Most of the payloads are classified, which is sponsored by the US Army’s Space Testing Program – a division dedicated to overseeing space activities for the Department of Defense. However, the two largest satellites, known as STPSat-6, also carry a NASA’s New Laser Communications Payload.
Also on board is a National Nuclear Security Administration payload, designed to detect nuclear explosions from space.
The smaller “carpool” satellite, known as LDPE-1 (EPSA Long-Life Propulsion Spacecraft), will test a space propulsion system and other technologies.
The Sunday morning launch will be ULA’s 190th total flight and the company’s longest mission to date, according to ULA officials.
“STP-3 is a unique mission, as Atlas V will deliver STP-3 directly to Geosynchronous Equatorial Orbit (GEO). This is a highly complex orbital insertion that requires three Centaur burns and precision cruising, a capability unique to Atlas V,” Gary Wentz, ULA’s vice president for government and business programs, said in a statement. “This is our longest mission to date, at seven hours and 10 minutes until the final chapter of the spacecraft.”
The launch follows the launch of this year’s 27th SpaceX rocket, which lifted off from a nearby platform on Thursday evening (December 2) and 50 satellites put into orbit, including 48 of the company’s Starlink Internet vessels.
Forty-fifth space delta meteorologists said that there are 90% chance of getting favorable conditions To take off on time in the early morning of Sunday. Weather deteriorated slightly on Monday (December 4) to attempt planned backups if needed.
