![]() ![]() The booster was fitted with a variety of technologies to facilitate the flight test, including grid fins and landing legs to facilitate the post-mission test. This was SpaceX's second attempt to land the booster on a floating platform after an earlier test landing attempt in January 2015 had to be abandoned due to weather conditions. Elon Musk later explained that the bipropellant valve was stuck, and therefore the control system could not react rapidly enough for a successful landing. The unmanned launch vehicle technically landed on the floating platform, however it came down with too much lateral velocity, tipped over, and was destroyed. Landing legs are in the midst of deploying.Īfter the separation of the second stage, SpaceX conducted a flight test and attempted to return the nearly-empty first stage of the Falcon 9 through the atmosphere and land it on a 90 m × 50 m (300 ft × 160 ft) floating platform called the autonomous spaceport drone ship. Post-launch flight test įalcon 9 first stage attempts landing on ASDS after second stage with SpaceX CRS-6 continued onto orbit. Return payload ĭragon returned 1,370 kg (3,020 lb) of cargo to Earth. Ī part of this payload includes science experiments from high schools, such as a project from Ambassador High School in Torrance, California. Also making the trip was a new espresso machine for space station crews. SpaceX CRS-6 included science payloads for studying new ways to possibly counteract the microgravity-induced cell damage seen during spaceflight, the effects of microgravity on the most common cells in bones, gather new insight that could lead to treatments for osteoporosis and muscle wasting conditions, continue studies into astronaut vision changes and test a new material that could one day be used as a synthetic muscle for robotics explorers of the future. However, there are certain restrictions included in their contract with NASA that preclude specified hazards on the secondary payloads, and also require contract-specified probabilities of success and safety margins for any SpaceX reboosts of the secondary satellites once the Falcon 9 second stage has achieved its initial low Earth orbit (LEO). SpaceX has the primary control over manifesting, scheduling and loading secondary payloads. Planet Labs will transport 14 Flock-1e Earth observation CubeSat satellites for later deployment from the space station via an agreement with Nanoracks, operator of the Center for the Advancement of Science in Space (CASIS).This is the second Arkyd 3 satellite in October 2014, the first Arkyd 3 satellite was destroyed on launch in the explosion of the Orbital Sciences Corporation Antares launch vehicle carrying it aboard the third Cygnus cargo resupply flight to the ISS. Planetary plans to deploy the smallsat from the ISS via a Nanoracks-provided service, in an attempt to validate and mature the technology of its Arkyd series of spacecraft. Planetary Resources will transport an Arkyd 3 - known as Arkyd 3 Reflight - to the ISS aboard Dragon on CRS-6.The Dragon spacecraft was filled with 2,015 kg (4,442 lb) of supplies and payloads, including critical materials to directly support about 40 of the more than 250 science and research investigations that will occur during Expedition 43 and Expedition 44. NASA has contracted for the CRS-6 mission from SpaceX and therefore determines the primary payload, date/time of launch, and orbital parameters for the Dragon space capsule.
