Dragon Splashes Down With Scientific Cargo for Analysis

SpaceX’s uncrewed Dragon cargo spacecraft splashed down at 2:53 p.m. EDT Saturday, Aug. 20, north of Cape Canaveral off the Florida coast, marking the return of the company’s 25th contracted cargo resupply mission to the International Space Station for NASA. The spacecraft carried more than 4,000 pounds of valuable scientific experiments and other cargo back to Earth.

Some of the scientific investigations returned by Dragon include:

• Space’s impact on materials: The Materials International Space Station Experiment-15-NASA (MISSE-15-NASA) experiment tests, qualifies, and quantifies the impact of the low-Earth orbit environment on new materials and components, such as spacecraft materials and wearable radiation protection. Successful experiment results could have applications both in the harsh environments of space and on Earth.

• Spacesuit cooling: Spacesuit Evaporation Rejection Flight Experiment (SERFE) demonstrates a new technology using water evaporation to remove heat from spacesuits and maintain appropriate temperatures for crew members and equipment during spacewalks. The investigation determines whether microgravity affects performance and evaluates the technology’s effect on contamination and corrosion of spacesuit material.

• Cell signaling in microgravity: The ESA (European Space Agency) sponsored investigation Bioprint FirstAid Handheld Bioprinter (Bioprint FirstAid) enables the rapid use of formerly prepared bio-inks, containing the patient’s own cells, to form a band-aid patch in the case of injury.

Dragon Departs Station to Return Scientific Cargo to Earth

At 11:00 a.m. EDT, flight controllers on the ground sent commands to release the uncrewed SpaceX Dragon spacecraft from the forward port of the International Space Station’s Harmony module. At the time of release at 11:05 a.m., the station was flying about 259 miles over the Pacific Ocean.

The Dragon spacecraft successfully departed the space station one month after arriving at the orbiting laboratory to deliver about 4,000 pounds of scientific investigations and supplies.

Tomorrow, ground controllers at SpaceX in Hawthorne, California, will command a deorbit burn. After re-entering Earth’s atmosphere, the spacecraft will make a parachute-assisted splashdown off the coast of Florida. NASA TV will not broadcast the de-orbit burn and splashdown, and updates will be posted on the agency’s space station blog.

Dragon arrived at the space station July 16, following a launch two days prior on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. It was the company’s 25th commercial resupply services mission to the space station for NASA.

Dragon Resupply Ship Departing Station Live on NASA TV

Live coverage of the departure of SpaceX’s uncrewed Dragon cargo spacecraft from the International Space Station is underway on NASA Television, the agency’s website, and the NASA app.

Ground controllers at SpaceX in Hawthorne, California, will send commands at approximately 11:00 a.m. EDT for Dragon to undock from the forward port of the station’s Harmony module and fire its thrusters to move a safe distance away from the station. Tomorrow, controllers will command a deorbit burn.

After re-entering Earth’s atmosphere, the spacecraft will make a parachute-assisted splashdown off the coast of Florida. NASA TV will not broadcast the de-orbit burn and splashdown. Updates will be posted on the agency’s space station blog.
