Description:

• DRAGON CRS-12 is a cargo resupply mission to the International Space Station, contracted to NASA. It is the X flight?? for SpaceX's uncrewed Dragon cargo spacecraft, and the nine?? SpaceX operational mission contracted to NASA under a Commercial Resupply Services contract. The mission brings equipment and supplies to the space station.
• The mission carries the 1258 kg CREAM package to study TeV cosmic rays, as well as the 45 kg KestrelEye IIM imaging satellite for the US Army and three NASA-sponsored cubesats: the 3U OSIRIS-3U space weather package for Penn State, the 6U Dellingr technology and space physics satellite for NASA-Goddard, and the 6U ASTERIA spacecraft for JPL and MIT. ASTERIA (formerly known as ExoplanetSat) will demonstrate arcsecond pointing with a cubesat, and perform stellar exoplanet transit photometry.
• CRS-12 is the last of the original order of twelve missions awarded to SpaceX under the CRS contract. Originally scheduled for December 2016, the flight was delayed multiple times to August 2017.

CRS-12 Dragon spacecraft grappled by Canadarm2.

Dragon docked to the ISS.

Mission details:

• Dragon CRS-12 was launched on Aug 14 2017 at 1631 UTC and arrived at the ISS on Aug 16.
• After Dragon rendezvoused with the ISS on 16 August 2017, the station's Canadarm2 grappled the spacecraft at 10:52 UTC. It was then berthed to the Harmony module at 13:07 UTC.
• Having been at the ISS for a month, the CRS-12 Dragon capsule was unberthed in the late hours of 16 September 2017 and was released by the Canadarm2 on 17 September at 08:40 UTC. After performing separation burns to take it out of the vicinity of the ISS, the Dragon performed a deorbit burn at 13:24 UTC, to enable atmospheric reentry. The spacecraft successfully landed in the Pacific Ocean at 14:14 UTC, returning approximately 1,700 kilograms (3,800 lb) of experiments and equipment to Earth. Te landing was near 120.9W 32.4N.
