SpaceX’s thirty first robotic cargo mission is headed again to Earth.
SpaceX’s Dragon cargo capsule undocked from the International Space Station (ISS) on schedule at this time (Dec. 16) at 11:05 a.m. EST (1605 GMT) at this time (Dec. 16). The spacecraft will start a sequence of deorbit burns to finish the corporate’s thirty first business resupply companies mission (CRS-31) for NASA, splashing down of the coast of Florida tomorrow (Dec. 17). The company will not webcast the splashdown however will present updates by way of its ISS weblog.
CRS-31 is returning to Earth with hundreds of kilos of apparatus and experiment specimens from ongoing microgravity analysis aboard the house station. Dragon is at present the one ISS cargo spacecraft able to returning tools and experiments safely to Earth. The different two operational freighters — Northrop Grumman’s Cygnus spacecraft and Russia’s Progress capsule — face a fiery atmospheric incineration, burning up throughout reentry, together with no matter waste from the house station is packed aboard them.
The CRS-31 Dragon launched to the ISS from NASA’s Kennedy Space Center (KSC) in Florida on Nov. 4, driving a SpaceX Falcon 9 rocket to low Earth orbit. The spacecraft rendezvoused with the orbital laboratory a day later, delivering about 6,000 kilos (2,700 kilograms) of science and provides for the Expedition 71 astronauts aboard.

Among these astronauts are NASA’s Butch Wilmore and Suni Williams, who initially launched to the station on the primary crewed flight of Boeing’s Starliner spacecraft in June. Complications with Starliner turned an eight-day mission into an eight-month stint aboard the ISS for the 2 astronauts. NASA ultimately determined to return Starliner to Earth uncrewed; Wilmore and Williams will come residence in February on SpaceX’s Crew-9 mission, which arrived on the station in September.
At the time of Starliner’s launch, the ISS was in want of a pump substitute for its urine processing system, which Wilmore and Williams had been tasked with delivering. To make room aboard the spacecraft, nevertheless, the 2 astronauts had been pressured to go away their very own baggage behind, together with their change of garments and different private objects.
Two different cargo missions preceded CRS-31 after Wilmore and Williams’ arrival — a Cygnus and a Progress mission, which had been in a position to relieve the astronauts of their house station hand-me-downs and provide them their very own shirts and toothbrushes. However, each cargo mission brings welcome items to the station’s whole crew, with a crowd-favorite provide of contemporary fruit and veggies.
Among the cargo CRS-31 delivered to the ISS final month had been contemporary meals, analysis tools, upkeep provides and private objects to assist maintain the orbiting astronauts.
NASA will have the ability to retrieve the CRS-31 Dragon spacecraft comparatively rapidly after splashdown tomorrow, reaping the advantages of any experiments in want of fast attending following atmospheric reentry. These experiments shall be transported to NASA’s Systems Processing Facility at KSC, the place scientists are in a position to proceed analysis within the post-microgravity setting.
Today’s undocking was initially speculated to happen on Dec. 6, however dangerous climate within the splashdown zone pushed it again repeatedly.
