Photos: Another SBIRS soars atop Atlas 5

A commercial mission developed by the Japanese company Astroscale rocketed into space on a Russian Soyuz launcher Monday with 37 other payloads, ready to kick off an orbital “dance” with two small spacecraft demonstrating how satellite sweepers might one day drag junk out of orbit.

Ground crews at Vandenberg Air Force Base on California’s Central Coast hoisted NASA’s InSight Mars lander atop a United Launch Alliance Atlas 5 rocket Monday, kicking off nearly two weeks of integrated tests and checkouts before the probe’s interplanetary launch window opens May 5.

A Soyuz rocket is scheduled to lift off Tuesday from a launch pad in Russia’s Far East with a new Russian weather satellite and 18 secondary payloads from companies and institutions in the United States, Canada, Japan, Norway, Sweden and Germany.
