SpaceX launches 50th Dragon spacecraft to ISS on resupply mission for NASA

SpaceX launched its 50th Dragon spacecraft mission to the International Space Station (ISS) on Sunday, delivering 5,000 lbs of supplies and scientific experiments. The CRS-33 mission also supports critical research for future human space exploration.

On Sunday, SpaceX launched its 50th mission to the International Space Station (ISS) with the CRS-33 Commercial Resupply Services mission from Cape Canaveral, Florida. The mission marked the Dragon spacecraft’s 50th visit to the station, with its first mission dating back to May 2012 as part of a resupply demonstration.

After stage separation, the first stage of the Falcon 9 rocket successfully landed on the A Shortfall of Gravitas droneship in the Atlantic Ocean. According to SpaceX officials, the Dragon spacecraft is expected to autonomously dock with the ISS on Monday following a 28-hour flight.

The CRS-33 mission will deliver 5,000 lbs (2,268 kg) of food, supplies, and scientific experiments to the astronauts aboard the space station. In addition to the resupply mission, the spacecraft will support approximately 50 critical scientific studies aimed at advancing future human space exploration. One of the key studies involves testing a hypothesis on blocking a specific protein to reduce bone loss in astronauts, as explained by Heidi Parris, associate program scientist for the ISS.

The launch also marked the seventh flight of the first-stage booster and the third resupply mission for this particular Dragon spacecraft. In September, the Dragon spacecraft will perform an altitude adjustment for the ISS as part of a reboost mission, with SpaceX providing this capability as part of its contract with NASA. Bill Spetch, the ISS Program’s Operations Integration Manager, noted that the ISS’s altitude gradually decays due to the thin atmosphere at that height, making reboost missions necessary.

The Dragon spacecraft is scheduled to return to Earth no earlier than December.
