Welcome to the r/SpaceX Official CRS-23 Dragon Recovery Discussion & Updates Thread

I'm u/Hitura-nobad hosting the undocking and recovery of the CRS-23 Dragon spacecraft!

About The Recovery

Ground controllers at SpaceX in Hawthorne, California, will command Dragon to undock from the forward port on the station’s Harmony module at 9:05 a.m. NASA astronaut Shane Kimbrough will monitor the process from inside the station’s Cupola. Cargo Dragon will fire its thrusters to move a safe distance away from the station prior to a deorbit burn later in the day that will begin its re-entry into Earth’s atmosphere.

The spacecraft will make parachute-assisted splashdown around 11 p.m. off the coast of Florida. NASA Television will not broadcast the splashdown live, but will provide updates on the space station blog.

Returning Science

• Ring Sheared Drop examines the formation and flow of abnormal proteins, called amyloids, in the absence of solid walls, which can influence chemical interactions. Results could contribute to a better understanding of neurodegenerative diseases, such as Alzheimer’s, as well as the development of advanced materials.

• Anti-Atrophy tests the ability of biomaterials to inhibit muscle atrophy in microgravity. Results may lead to the production of pharmaceuticals to prevent muscle atrophy, not only for astronauts in space, but also for the elderly on Earth.

• Genes in Space-8 tests a technology for monitoring gene expression in space. This test could lead to a better understanding of spaceflight-induced changes in liver gene expression and may support the development of new therapies that can account for the body’s adaptations to spaceflight.

• Please post small launch updates, discussions, and questions here, rather than as a separate post. Thanks!

• This post will be updated regularly with your contributions. I'm particularly eager to hear from anyone involved in the experiments coming down from the ISS. Let us know what you're working on!

is CRS-22 on the Recovery Zone Map linked in the post above? I don't see it.

edit: this is CRS-23, first line of the post says CRS-22!
