The SpaceX Falcon 9 rocket carrying the Dragon spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on March 14, 2023, on the company’s 27th commercial resupply services mission for the agency to the International Space Station. Liftoff was at 8:30 p.m. EDT. Dragon will deliver more than 6,000 pounds of cargo, including a variety of NASA investigations, supplies, and equipment to the crew aboard the space station, including the final two experiments comprising the National Institutes for Health and International Space Station National Laboratory’s Tissue Chips in Space initiative, Cardinal Heart 2.0 and Engineered Heart Tissues-2. The spacecraft is expected to spend about a month attached to the orbiting outpost before it returns to Earth with research and return cargo, splashing down off the coast of Florida.
