SpaceX launched the CRS-33 mission from Cape Canaveral on Sunday, sending Dragon to the ISS for the 50th time.
The first stage separated successfully and landed on the droneship A Shortfall of Gravitas in the Atlantic Ocean.
SpaceX confirmed the Dragon spacecraft will autonomously dock with the ISS on Monday after a 28-hour flight.
Resupply and Scientific Research
The CRS-33 mission delivers 5,000 lbs (2,268 kg) of food, supplies, and experiments to ISS astronauts.
SpaceX officials highlighted that the mission also supports 50 scientific studies critical for future human space travel.
Researchers will test whether blocking a protein that drives bone loss can protect astronauts’ bone health.
Heidi Parris, ISS associate program scientist, said the study may reduce bone deterioration in microgravity.
Upcoming Reboost and Return
Sunday’s launch marked the first-stage booster’s seventh flight and Dragon’s third CRS mission.
NASA will use Dragon in September to boost the ISS, adjusting its orbit to counter atmospheric drag.
Bill Spetch, ISS Operations Integration Manager, explained the reboost helps maintain the station’s operational altitude.
Dragon will return to Earth no earlier than December, carrying completed experiments and supplies.
