Principal payload ws a SpaceX Dragon
spacecraft carrying a cargo to the ISS under NASA's Commercial Resupply Services (CRS) contract.
Precise launch time aimed 19:25:22 UTC.
Launch was originally targeted at a one month period that opened Jan 17. Scheduled for Mar 31 then postponed because of a problem with a radar system downrange from the launch site. Countdown was running April 14 when a leak was detected from a Helium tank in the Falcon 9 first stage about 75 mins before planned lift off (19:58 UTC). Launch was postponed.
SpaceX press kit:
The launch vehicle also carried NASA's ELaNa 5
(Educational Launch of Nanosatellites) cluster of five Cubesats, in four P-POD dispensers, that will be released after separation of the Dragon spacecraft:
- 3U Cubesat that will release 104 Sprites (postage stamp shape/size - 32mm x 32mm, individual satellites) for organisations that sponsored them. Each Sprite will transmit a unique code to identify its sponsor plus data from a small sensor. KickSat itself also carries logos and signatures of individuals and organisations that sponsored the launch with donations.
The Sprites will probably not get catalogued. They will re-enter the Earth's atmosphere within a few days of release.
- 1U Cubesat from NASA Ames laboratory, fourth in a series of missions designed to use commercially available smartphone technology as part of low-cost satellite development, technology demonstor as a pathfinder for the
Edison Demonstration of Smallsat Network,
(TESTSat-Lite) - 2U cubesat from Taylor University, Indiana, will use a GlobalStar satellite communication modem to demonstrate a reliable and global nanosat network, and will observe space weather with a plasma probe, 3-axis magnetometer, and three ultraviolet photodiodes,
(Agile Low-cost Laboratory for Space Technology Acceleration and Research/Telescopic High-definition Earth Imaging Apparatus) - 3U Cubesat, sponsored by the Colorado Space Grant Consortium (CoSGC) and Lockheed Martin, for full-colour imaging of the Earth's surface to demonstrate the capabilities of a new Cubesat design,
- 3U Cubesat to study how plant cells sense gravity, joint mission between NASA’s Ames Research Center and the Department of Agricultural and Biological Engineering at Purdue University,
NASA ELaNa 5 factsheet:
Falcon 9's first stage was fitted with landing legs as part of SpaceX ongoing development of recovery systems. In this case, the Falcon 9 simulated a landing in the Atlantic Ocean about 450 km from the launch site but was not retrieved.
