SpaceX Cargo Dragon Splashes Down Loaded With Science Experiments - CleanTechnica

The insignia for the SpaceX CRS-21 mission that saw the upgraded Cargo Dragon resupply ship automatically dock to the Harmony module’s space-facing international docking adapter, a first for a U.S.

SpaceX’s upgraded Dragon cargo spacecraft splashed down at 8:26 p.m.

EST on Wednesday west of Tampa off the Florida coast, marking the return of the company’s 21st contracted cargo resupply mission to the International Space Station for NASA.

The spacecraft carried more than 4,400 pounds of valuable scientific experiments and other cargo back to Earth.

The upgraded cargo Dragon capsule used for this mission contains double the powered locker availability of previous capsules, allowing for a significant increase in the research that can be delivered back to scientists.

Sailors have navigated via sextants for centuries, and NASA’s Gemini missions conducted the first sextant sightings from a spacecraft.

This investigation tested specific techniques for using a sextant for emergency navigation on spacecraft such as NASA’s Orion, which will carry humans on deep-space missions.

This technology demonstration tested a method to remove carbon dioxide (CO2) from air aboard the International Space Station, using actively heated and cooled amine beds
