Atlas 5

United Launch Alliance rolled out its next Atlas 5 rocket Thursday to a launch pad at Cape Canaveral, moving the launcher into position for blastoff Saturday at 5:34 a.m. EDT (0934 GMT) with NASA’s Lucy mission, a robotic spacecraft to explore the Trojan asteroids in the outer solar system.

Ground teams are stepping through testing of three small CubeSats launched with the Landsat 9 remote sensing satellite last month, preparing the small spacecraft for exoplanet observations and communications experiments. NASA says engineers have not established contact with another CubeSat designed for space weather research.

Teams at Cape Canaveral transferred NASA’s Lucy asteroid explorer to a United Launch Alliance integration building Thursday and mounted the robotic science probe atop an Atlas 5 rocket for liftoff later this month, using a booster originally built to send astronauts into space.

Set for launch Oct. 16 on a flight to explore asteroids in the outer solar system, NASA’s Lucy spacecraft has been fueled and encapsulated inside the payload fairing of its Atlas 5 rocket. Watch as Chris McCaa, a manager from spacecraft manufacturer Lockheed Martin, points out some of the features of the probe.

Fueled up for a 12-year mission of exploration, NASA’s Lucy science probe is nearly ready for launch Oct. 16 from Florida’s Space Coast to begin a journey through the solar system to visit eight asteroids, a record number for a single mission.

Shrouded in a veil of fog, an Atlas 5 rocket fired away from Vandenberg Space Force Base in California Monday with the Landsat 9 remote sensing satellite.

NASA and United Launch Alliance deployed a new Landsat satellite in orbit Monday after liftoff on an Atlas 5 rocket from Vandenberg Space Force Base in California, marking the 2,000th launch from the West Coast spaceport since 1958 and extending a series of Earth observations used by farmers, urban planners, and climate scientists.

A United Launch Atlas 5 rocket is set for launch with the Landsat 9 satellite, a joint project between NASA and the U.S. Geological Survey, and four small CubeSat rideshare payloads.

NASA and United Launch Alliance launched the Landsat 9 satellite aboard an Atlas 5 rocket Monday at 11:12 a.m. PDT (2:12 p.m. EDT; 1812 GMT) from Vandenberg Space Force Base, California. The new satellite, developed in partnership with the U.S. Geological Survey, will extend an unbroken nearly 50-year record of environmental images.
