CRS-31 Arrives at International Space Station
SpaceX Dragon Spacecraft Transported More Than 6,000 Pounds of Supplies
Following a successful launch of NASA’s SpaceX 31st commercial resupply mission, new scientific experiments and cargo for the agency have arrived at the International Space Station.
“The whole idea of education is to prepare our students for the real world. A very effective way to do that is to bring professional experiences into the classroom and ask our students to be scientists and engineers right now.”
Jeff Goldstein
The SpaceX Dragon spacecraft, carrying more than 6,000 pounds of supplies to the orbiting laboratory, lifted off at 9:29 p.m. EST Monday, on the company’s Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Docking occurred Tuesday morning.
The resupply mission is supporting dozens of research experiments conducted during Expedition 72. In addition to food, supplies, and equipment for the crew, Dragon will deliver several new experiments, including the Coronal Diagnostic Experiment, to examine solar wind and how it forms. Dragon also delivers Antarctic moss to observe the combined effects of cosmic radiation and microgravity on plants. Other investigations aboard include a device to test cold welding of metals in microgravity and an investigation that studies how space impacts different materials.
It also includes 39 student-led projects from 38 communities as part of the Student Spaceflight Experiments Program (SSEP). SSEP is an ISS National Laboratory educational partner program aiming to equip the next generation of scientists and engineers by integrating the scientific research process into the classroom.
“The whole idea of education is to prepare our students for the real world," said Jeff Goldstein, center director of the National Center for Earth and Space Science Education (NCESSE), which runs SSEP. Goldstein explained that for educators to be successful in fostering a robust future workforce in science, technology, engineering, and mathematics (STEM), students need hands-on experience performing tasks from those careers. “A very effective way to do that is to bring professional experiences into the classroom and ask our students to be scientists and engineers right now.”
Participating communities—each with 100 or more students for elementary and secondary programs and at least 30 for college-level programs—engage in a formal microgravity science curriculum and then break into smaller teams to create research proposals. Student experiments are designed to be carried out using Mixstix, flexible tubes with three clamped compartments to keep substances separate until they are ready to be mixed in space. For this mission, SSEP received nearly 1,900 proposals, and a review board selected the top experiment from each community to launch into space.
These are just a sample of the hundreds of investigations conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Such research benefits humanity and lays the groundwork for future human exploration through the agency’s Artemis campaign, which will send astronauts to the Moon to prepare for future expeditions to Mars.
The Dragon spacecraft is scheduled to remain at the space station until December when it will depart the orbiting laboratory and return to Earth with research and cargo, splashing down off the coast of Florida.
