(Image credit: NASA) A SpaceX cargo capsule is set to head back toward Earth on Dec. 12, and you can watch the action live. A robotic Dragon freighter will undock from the International Space Station's (ISS) Harmony module on Thursday, Dec. 12 at 11:05 a.m. EST (1605 GMT), if all goes according to plan. An undocking attempt set for Dec. 6 was delayed "due to forecasted unfavorable weather conditions at the splashdown site off the coast of Florida" NASA said in a statement. NASA will stream the departure live, beginning at 10:50 a.m. EST (1550 GMT). Space.com will carry the feed as well, if the agency makes it available. This Dragon is flying SpaceX's 31st contracted ISS resupply mission for NASA, which explains the flight's name: CRS-31. The capsule delivered about 6,000 pounds (2,700 kilograms) of food, equipment and scientific experiments to the station on Nov. 5. You may like
