SpaceX launched its 33rd resupply mission to the International Space Station (ISS) early Sunday morning. A Falcon 9 rocket lifted off from Cape Canaveral at 2:45 a.m. ET, carrying a Dragon capsule filled with 2.5 tons of supplies and an important thruster kit for maintaining the station’s altitude.
Just under ten minutes later, the rocket’s first stage successfully landed on a droneship, and the Dragon capsule began its journey to the station. If everything goes as planned, it will dock on Monday at 7:30 a.m. The cargo includes over 2,400 pounds of crew supplies, around 1,000 pounds of scientific equipment, and various hardware parts.
A fun fact from Bill Spetch, the ISS operations and integration manager: Space crews often prefer tortillas over bread. “They don’t make crumbs that float away in weightlessness,” he explained.
NASA has exciting plans for the future, marking 25 years of continuous human presence on the ISS this November. During this time, the station has supported over 4,000 scientific experiments from 110 countries. The recent CRS-33 mission will kick off 50 new research projects, examining topics from bone loss in microgravity to 3D printing for creating medical devices in space.
Heidi Parris, an associate program scientist for the ISS, emphasized the importance of these studies. One particular project aims to create a 3D-printed device that can help regenerate nerves after injury. This could be a crucial step for medical advancements.
Additionally, the launch included a specialized propulsion system with two SpaceX Draco engines to help maintain the ISS’s altitude. This system is significant since the station gradually loses altitude due to atmospheric drag. While Russian spacecraft typically handle such operations, this mission introduces a new capability for the Dragon capsule.
Sarah Walker from SpaceX mentioned that the new thruster kit will help maintain the ISS’s altitude by providing a quarter of the yearly propulsion needed. The first adjustment is scheduled for September 3, which will set the stage for a series of altitude-boosting burns throughout the fall.
As we look to the future, this mission reflects the ongoing commitment to space exploration and international collaboration in scientific research. Each launch contributes to a growing body of knowledge that could one day benefit humanity on Earth and beyond. For more insights into space missions and their impact, visit NASA’s official site.
