NASA and space agencies across the globe are opening up new possibilities for space exploration with missions to comets, asteroids, and other celestial bodies. <\/p>\n
Following NASA, European Space Agency (ESA), and Indian Space Research Organisation (ISRO) spacecraft observations of the close flyby of Mars by comet Siding Spring in October, and the successful November landing of ESA's Philae lander on comet 67P\/Churyumov-Gerasimenko, the Japan Aerospace Exploration Agency (JAXA) successfully launched its Hayabusa2 mission on Dec. 3 to rendezvous with an asteroid, land a small probe plus three mini rovers on its surface, and then return samples to Earth. <\/p>\n
NASA and JAXA are cooperating on the science of the mission and NASA will receive a portion of the Hayabusa2 sample in exchange for providing Deep Space Network communications and navigation support for the mission. <\/p>\n
Hayabusa2 builds on lessons learned from JAXA's initial Hayabusa mission, which collected samples from a small asteroid named Itokawa and returned them to Earth in June 2010. Hayabusa2's target is a 750 meter- wide asteroid named 1999 JU3, because of the year when it was discovered by the NASA-sponsored Lincoln Near-Earth Asteroid Research project, Lexington, Massachusetts. <\/p>\n
This is a C-type asteroid which are thought to contain more organic material than other asteroids. Scientists hope to better understand how the solar system evolved by studying samples from these asteroids. <\/p>\n
\"We think of C-type asteroids as being less altered than others,\" says Lucy McFadden, a planetary scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. \"Bringing that material back and being able to look at it in the lab - I think it's going to be very exciting.\" <\/p>\n
On Nov. 17, NASA and JAXA signed a Memorandum of Understanding for cooperation on the Hayabusa2 mission and NASA's Origins, Spectral Interpretation, Resource Identification, Security - Regolith Explorer (OSIRIS-REx) mission to mutually maximize their missions' results. <\/p>\n
OSIRIS-REx is scheduled to launch in 2016. It will be the first U.S. asteroid sample return mission. OSIRIS-REx will rendezvous with the 500-meter-sized asteroid Bennu in 2019 for detailed reconnaissance and a return of samples to Earth in 2023. <\/p>\n
Hayabusa2 and OSIRIS-REx will further strengthen the two space agencies' relationship in asteroid exploration. <\/p>\n
The missions will also help NASA choose its target for the first-ever mission to capture and redirect an asteroid. NASA's Asteroid Redirect Mission (ARM) in the 2020s will help NASA test new technologies needed for future human missions for the Journey to Mars. <\/p>\n
