This set of 16 photos reveals the OSIRIS-REx spacecraft’s regular method towards the asteroid Bennu over the last half of October 2018. From Oct. 12 to Oct. 29, the long-range PolyCam digital camera took one optical navigation picture per day, besides on Oct. 16 and 17 when PolyCam was not scheduled to take photos.

The spacecraft was roughly 27,340 miles (44,000 km) from Bennu for the primary picture – a distance a number of thousand miles higher than the circumference of the Earth. The final picture was taken from a distance of round 200 miles (320 km), or barely lower than the gap between Los Angeles and Las Vegas.

NASA’s OSIRIS-REx Executes Third Asteroid Strategy Maneuver

NASA’s OSIRIS-REx spacecraft executed its third Asteroid Strategy Maneuver (AAM-Three) at this time. The trajectory correction maneuver (TCM) thrusters fired in a sequence of two braking maneuvers designed to sluggish the spacecraft’s velocity relative to Bennu from roughly 11.7 mph (5.2 m/sec) to .24 mph (.11 m/sec). Because of constraints that science devices not be pointed too carefully to the Solar, this maneuver was designed as two separate burns of roughly 5.eight mph (2.6 m/sec) every, to perform a internet change in velocity of round 11.5 mph (5.13 m/sec).

The mission workforce will proceed to look at telemetry and monitoring knowledge over the following week to confirm the brand new trajectory. The maneuver focused the spacecraft to fly by means of a hall designed for the gathering of high-resolution photos that will probably be used to construct a form mannequin of Bennu.

The OSIRIS-REx spacecraft is within the midst of a six-week sequence of ultimate method maneuvers. AAM-1 and AAM-2, which executed on Oct. 1 and Oct. 15 respectively, slowed the spacecraft by a complete of roughly 1,088 mph (486 m/sec). The final of the burns, AAM-Four, is scheduled for Nov. 12 and can regulate the spacecraft’s trajectory to reach at a place 12 miles (20 km) from Bennu on Dec. Three.

Greenbelt MD (SPX) Oct 31, 2018

NASA’s mission to carry out the primary reconnaissance of the Trojans, a inhabitants of primitive asteroids orbiting in tandem with Jupiter, has handed a essential milestone. NASA has given approval for the implementation and 2021 launch of the Lucy spacecraft.

The affirmation assessment, formally often called “Key Determination Level C,” licensed continuation of the mission into the event section and set its value and schedule. The affirmation assessment panel accepted the detailed plans, instrument suite, budge … read more
