Virgin Orbit conducts drop-test of rocket from Boeing 747

LOS ANGELES (AP) — Virgin Galactic's sister company Virgin Orbit conducted a drop test of its air-launched satellite booster over California on Wednesday, a key step toward space missions.

The 70-foot (21.3-meter) LauncherOne rocket was released from a Boeing 747 flying 35,000 feet (10,668 meters) over an Edwards Air Force Base test range in the Mojave Desert.

The purpose of the test was to observe how the rocket detached from the 747's wing and its free-fall to the desert floor before the first actual orbital launch later this year.

The company tweeted that the crews of the 747 and a chase plane reported "a good, clean release ."

The test did not involve the ignition of the rocket motor.

"All crews have landed safely, and we're extremely happy with how it all went," said company spokesman Kendall Russell in an email to The Associated Press.

The Long Beach, California-based company founded by Richard Branson will use the system to launch small satellites — weighing from about 660 to 1,100 pounds (300 to 500 kilograms) — into space.

The 747 — named Cosmic Girl — will fly from multiple locations around the globe, enabling access to orbits that are more difficult to reach from fixed launch sites.

Virgin Orbit recently announced an agreement with ANA Holdings, parent of All Nippon Airways, to bring its service to Japan.

The memorandum of understanding calls for ANA to evaluate its capability to provide ground support, maintenance and possibly aircraft.

Virgin Orbit plans its initial launch missions to fly out of Mojave Air and Space Port in the California desert.

Other sites may include Kennedy Space Center in Florida, Andersen Air Force Base on Guam, the United Kingdom's Spaceport Cornwall and the Taranto-Grottaglie Airport in Italy.

Virgin Galactic, meanwhile, is moving personnel from Mojave, where it developed its space tourism rocket plane, to Spaceport America in southern New Mexico in preparation for commercial operations.

Virgin Galactic this week announced a merger with Social Capital Hedosophia and plans to go public.
