Cargo Dragon Departs Station, Returns to Earth Friday

Mark Garcia Posted on July 8, 2021

With NASA astronaut Shane Kimbrough  monitoring aboard the International Space Station, a SpaceX cargo Dragon spacecraft undocked from the International Docking Adapter on the station’s space-facing port of the Harmony module at 10:45 a.m. EDT.

Dragon will fire its thrusters to move a safe distance from the space station during the next 36 hours. On Friday, July 9, Dragon will conduct a deorbit burn to begin its re-entry sequence into Earth’s atmosphere. Dragon is expected to splash down at approximately 11:29 p.m. in the Gulf of Mexico near Tallahassee, Florida. The splashdown will not be broadcast.

Splashing down off the coast of Florida enables quick transportation of the science aboard the capsule to the agency’s Kennedy Space Center’s Space Station Processing Facility, delivering some science back into the hands of the researchers as soon as four to nine hours after splashdown. This shorter transportation timeframe allows researchers to collect data with minimal loss of microgravity effects. The Dragon’s departure will be the second splashdown of a U.S. commercial cargo craft off the Florida coast. Previous cargo Dragon spacecraft returned to the Pacific Ocean, with quick-return science cargo processed at SpaceX’s facility in McGregor, Texas, and delivered to NASA’s Johnson Space Center in Houston.

Dragon launched June 3 on a SpaceX Falcon 9 rocket from Launch Complex 39A at Kennedy, arriving at the station a little less than 16 hours later. The spacecraft delivered more than 7,300 pounds of research investigations, crew supplies, and vehicle hardware to the orbiting outpost. Dragon’s external cargo “trunk” carried six new ISS Roll-Out Solar Arrays (iROSAs), two of which Expedition 65 crew members Kimbrough and Thomas Pesquet, an ESA (European Space Agency) astronaut, installed during three spacewalks June 16, 20, and 25.

Some of the scientific investigations Dragon will return to Earth include:

Lyophilization-2 examines how gravity affects freeze-dried materials and could result in improved freeze-drying processes for pharmaceutical and other industries. Freeze-drying also has potential use for long-term storage of medications and other resources on future exploration missions.
Molecular Muscle Experiment-2 tests a series of drugs to see whether they can improve health in space, possibly leading to new therapeutic targets for examination on Earth.
Oral Biofilms in Space studies how gravity affects the structure, composition, and activity of oral bacteria in the presence of common oral care agents. Findings could support development of novel treatments to fight oral diseases such as cavities, gingivitis, and periodontitis.

The #CargoDragon 22 left earlier after barely a month in orbit. Cargo or Crew Dragon, start or finish: who can tell the difference?

Today @SpaceX #CargoDragon left us after a month on board. Can you tell if these pictures are of the undocking or of the docking in June?

Anyone know if Dragon will be coming down from the north or south? Hoping to photograph the re-entry. I managed to get CRS-21, hoping tot get this one too.

ESA's ISS Tracker Map shows it coming up from the south for now (with not much time left until entry), and since the ISS and Dragon should be in almost exactly the same plane regardless of maneuvers since undocking, that would be my guess.

EDIT: Forgot that splashdown was tomorrow, not today.  Luckily, the result is the same, thanks to Earth's solar day being pretty close to its sidereal day, and the ISS's orbit being a fairly unperturbed one.

As expected, the latest TLEs from CRS-22 do not show its ground track passing through the recovery zone. An orbit lowering maneuver will be needed between now and tomorrow afternoon to move the ground track appropriately.
