A SpaceX Cargo Dragon 2 spacecraft has safely returned to Earth after delivering a number of tons of NASA provides to the Worldwide Area Station (ISS).
Somewhat over six weeks after Falcon 9 launched SpaceX’s twenty sixth Industrial Resupply Providers 2 (CRS2) mission for NASA, Dragon departed the ISS on January ninth. Effectively reducing its orbit with a number of small Draco thrusters took about 36 hours, and reusable Dragon 2 capsule C211 finally slowed to the purpose that it started impacting Earth’s environment. Utilizing its ablative warmth defend like a brake pad, Dragon slowed from a velocity of seven.5 kilometers per second (16,800 mph) to about 155 meters per second (~350 mph) earlier than starting parachute deployment.
At 5:19 am on January eleventh, the Dragon capsule gently splashed down off the coast of Tampa, Florida, and was rapidly secured by a SpaceX restoration ship. As soon as onboard, the capsule was opened up, and cargo contemporary from orbit was loaded onto a helicopter as rapidly as doable. That system – primarily created to quickly transport astronauts again to NASA medical amenities – additionally signifies that scientists can get entry to their recovered ISS experiments only a handful of hours after Cargo Dragon splashes down.
Among the scientific investigations returned by Dragon embody:
Deep house radiation safety: A vest designed to guard astronauts from excessive doses of radiation attributable to unpredictable photo voltaic particle occasions is returning to Earth after months of testing. Crew members wore the Astrorad vest whereas performing every day duties and offered suggestions about how straightforward it’s to placed on, the way it suits and feels, and the vary of movement doable whereas sporting it. The vest’s builders plan to make use of that suggestions to enhance design of the garment, which might present radiation safety for astronauts on Artemis missions to the Moon.
Air, water, crops: XROOTS used hydroponic (water-based) and aeroponic (air-based) methods to develop crops with out soil or different progress media. Researchers collected video and nonetheless pictures to guage progress chambers via the flowers cycle from seed germination via maturity. The plant chambers are returning to Earth for added evaluation. Comparable methods may very well be used to supply crops for future house missions and to boost cultivation and meals safety for the good thing about folks on Earth.
Bioprospecting in house: Bioprospecting is the method of figuring out crops and animals that will comprise substances with potential to be used as medicine, biochemicals, and extra. Earlier research discovered that house could cause genetic and physiological adjustments that would lead to microbes yielding such supplies. Rhodium Microgravity Bioprospecting-1 studied a option to seek for these microbes. The science chambers and temperature logger from the investigation are returning to Earth for additional examination.”

SpaceX’s second-generation Cargo Dragon spacecraft is almost equivalent to Crew Dragon. Each are made up of two important components: a reusable capsule and an expendable ‘trunk.’ The Dragon 2 trunk is a tube-like carbon fiber composite construction lined by a pores and skin of curved photo voltaic arrays and radiators. It may additionally maintain a number of tons of unpressurized cargo.
Dragon’s capsule holds a stress vessel, environmental management programs (ECLSS), all 16 Draco maneuvering thrusters, propellant tanks, docking programs, and an ablative warmth defend. Within the case of Crew Dragon, the capsule can be outfitted with home windows, crew seats, hand management, and SuperDraco launch abort thrusters. Each Cargo and Crew Dragon capsules symbolize the overwhelming majority of the overall spacecraft value and may be recovered, refurbished, and reflown in as little as 4 months.
NASA is SpaceX’s solely Cargo Dragon buyer. January eleventh’s restoration marked the completion of CRS2 Spx-26, SpaceX’s twenty fifth profitable ISS resupply mission since 2012. After including extra contracts final 12 months, NASA has preparations for not less than 9 extra Dragon 2 resupply missions stretching into 2026 or 2027. NASA additionally signed contracts for eight Crew Dragon astronaut launches in 2022 and has 9 missions on contract between now and the late 2020s or 2030.
Whereas Falcon 9 infamously failed in the course of the June 2015 launch of CRS-7, each Dragon that has ever reached orbit has been recovered in a single piece. Spx-26 was Dragon’s thirty eighth mission general and thirty fifth consecutively profitable restoration from orbit.
