A new era of human spaceflight is set to begin as American astronauts once again launch on an American rocket from American soil to the International Space Station as part of NASA’s Commercial Crew Program. NASA astronauts Robert Behnken and Douglas Hurley will fly on SpaceX’s Crew Dragon spacecraft, lifting off on a Falcon 9 rocket at 4:32 p.m. EDT on May 27, from Launch Complex 39A in Florida, for an extended stay at the space station for the Demo-2 mission. The specific duration of the mission is to be determined.
As the final flight test for SpaceX, this mission will validate the company’s crew transportation system, including the launch pad, rocket, spacecraft, and operational capabilities. This also will be the first time NASA astronauts will test the spacecraft systems in orbit.
The Demo-2 mission will be the final major step before NASA’s Commercial Crew Program certifies Crew Dragon for operational, long-duration missions to the space station. This certification and regular operation of Crew Dragon will enable NASA to continue the important research and technology investigations taking place onboard the station, which benefits people on Earth and lays the groundwork for future exploration of the Moon and Mars with the agency’s Artemis program.
Canadian astronaut David Saint-Jacques began growing two new crops aboard the International Space Station on Saturday, March 9, 2019. The two crops, Wasabi Mustard Greens and Extra Dwarf Pak Choi, are part of experiment Veg-03 H. Saint-Jacques placed six “plant pillows” into the veggie growth chamber. This experiment is part of ongoing research on the space station and on Earth to identify fresh vegetables capable of providing astronauts food and nutrition during long-duration spaceflight, including future missions to the Moon or Mars.
Each pillow serves as a pot designed for space with pre-packed seeds, a substance for the roots to grow into, controlled-release fertilizer, and a way for the in-orbit gardeners to water their plants in microgravity.
High school and middle school students participating in the Fairchild Tropical Botanic Garden’s Growing beyond Earth Challenge identified Extra Dwarf Pak Choi as a potential candidate crop for space through classroom science experiments, along with Dragoon Lettuce, which NASA astronaut Serena Auñón-Chancellor grew on the station last fall. Using science stations designed to mimic conditions on the space station gave students a chance to grow plants and record data that NASA was able to use. Those experiments culminated in the plant species which launched to the space station aboard the 15th SpaceX cargo resupply mission on June 29, 2018, along with three other plant species.
The experiment should take 30 days to complete and will provide data on food safety for the new crops to compare to ground studies in order to establish a baseline.
“I think the astronauts will be surprised to learn that the Extra Dwarf Pak Choi that they grow and eat has the same amount of Vitamin C by weight as does a fresh Florida orange,” said NASA scientist Matt Romeyn, “and the leaves don’t taste much different than other fresh leafy greens.”
