NASA’s OSIRIS-REx asteroid mission arrives at Kennedy Space Center

This afternoon, NASA announced that it will launch its OSIRIS-REx (which stands for Origins, Spectral Interpretation, Resource Identification, Security – Regolith Explorer) spacecraft on September 8th.

OSIRIS-REx now enters final preparations for launch on a United Launch Alliance Atlas 5, currently scheduled for Sept. 8 from Cape Canaveral at the beginning of a launch window that lasts a little more than one month. Immediately after landing, the spacecraft was transported to the Payload Hazardous Servicing Facility here to begin that work.

The spacecraft will rendezvous with the near Earth asteroid Bennu in August 2018. OSIRIS-REx will study the asteroid with a suite of instruments including cameras, spectrometers and a laser altimeter.

OSIRIS-REx will also deploy a robotic arm to collect at least 60 grams of asteroid samples. The spacecraft will depart Bennu in March 2021 and return the samples to Earth in September 2023.

OSIRIS-REx will be NASA’s first mission to return samples from the asteroid, but not the first mission overall. Japan’s Hayabusa spacecraft collected samples from the asteroid Itokawa in 2005 and returned them to Earth in 2010. Hayabusa 2, a follow-up mission launched in December 2014, will collect samples from the asteroid Ryugu and return them to Earth in 2020.

OSIRIS-REx is the third in NASA’s New Frontiers series of medium-class planetary science missions. The first, New Horizons, flew past Pluto in July 2015. Juno, the second New Frontiers mission, will enter orbit around Jupiter on July 4.

For those curious about where to watch the launch live, the details are slim, but chances are you’ll find it on NASA’slivestream or on their YouTube channel.
