Successful OSIRIS-REx Maneuver

(JAN 17) New tracking data confirms that NASA’s OSIRIS-REx spacecraft aced its first Deep Space Maneuver (DSM-1) on Dec. 28, 2016. The engine burn sets up the spacecraft for an Earth gravity assist this fall as it continues its two-year journey to the asteroid Bennu.

The large maneuver was the first using OSIRIS-REx’s main engines and resulted in a 964 miles per hour (431 meters per second) change in the vehicle’s velocity utilizing 780 pounds (354 kilograms) of fuel.

DSM-1 represents the first major, post-launch milestone for OSIRIS-REx. The significant change in trajectory from DSM-1 was necessary to put OSIRIS-REx on course for an encounter with Earth in September of this year.

A smaller trajectory correction maneuver will be executed on Wednesday, Jan. 18 to refine the course for the Earth flyby, during which Earth’s gravity will bend the OSIRIS-REx trajectory and slinging it toward a rendezvous with the asteroid Bennu in the fall of 2018.

Dante Lauretta of the University of Arizona, Tucson, is the principal investigator, and the University of Arizona also leads the science team and the mission’s observation planning and processing. Lockheed Martin Space Systems in Denver built the spacecraft and is providing spacecraft flight operations.

Falcon 9 Launched

(JAN 14) A Falcon 9 rocket carrying 10 Iridium Next communications satellites was successfully launched at 9:54:39 PST this morning from Vandenberg AFB, Calif. Iridium Communications, Inc. reports the satellites were successfully delivered into low-Earth orbit about one hour after launch.

I observed the launch with several aerospace enthusiasts from a high bluff west of Newbury Park, approximately 100 statute miles east-southeast of the launch site. The first stage's orange flame and contrail were easily visible to the unaided eye.

Using tripod-mounted 10x50 binoculars, I could clearly see the rocket's shape and shock diamonds in the first stage's flame. As the Falcon 9 gained altitude, the binoculars showed an expanding, tenuous exhaust plume. Following stage 1/2 separation, the shapes of both stages and the widening gap between them were visible through the binoculars.

I attempted to continue tracking the first stage after separation in hopes of seeing re-ignition of the engines for the subsequent soft-landing attempt. Unfortunately, shortly after staging, my binoculars suddenly unlocked, pitched up, and pointed in the wrong area of the sky. I regained control of the binoculars and scanned the sky, but could not find the first stage.

Launch Delayed

(JAN 8) Monday’s planned launch of a Falcon 9 rocket from Vandenberg Air Force Base has been delayed. The launch is tentatively scheduled for Saturday, January 14.

Hawthorne, California-based SpaceX, builder of the Falcon 9, plans to launch the rocket at 9:54:34 a.m. PST from Space Launch Complex 4-East at south Vandenberg. If the launch goes as planned, the rocket will rise vertically for several seconds, gradually turn southward, and carry ten Iridium Next communications satellites into orbit.

The best location for the public to view the launch is probably the west side of Lompoc near state highway 246. If the weather cooperates, the bright orange flame from the rocket’s first stage could be visible over a wide area.

It is not known if SpaceX plans to make a powered landing of the rocket’s first stage.

This will be the first launch of a Falcon 9 rocket since the catastrophic explosion of a Falcon 9 on the launch pad during a test in Florida last September.
