Your challenge is to tell us the location of the satellite image and why it is interesting.

SpaceX-29 (SpX-29) Undock and Return: SpX-29 Cargo Dragon successfully undocked from the ISS on Thursday, December 21st, at 4:00 PM CST. Shortly after, Dragon completed a short return trajectory and splashed down safely off the coast of Tallahassee, FL at 11:32 AM CST. SpX-29 was successfully recovered, and returned cargo and payloads to the ground, …

Two spaceships in two days have departed the International Space Station and the Expedition 70 crew will spend Christmas and New Year’s Day orbiting Earth. NASA astronaut Loral O’Hara monitored the Canadarm2 robotic arm release of the Cygnus space freighter on Friday, Dec. 22. Earlier, ground engineers remotely maneuvered the Canadarm2 and detached Cygnus from …

At 8:06 a.m. EST, Northrop Grumman Cygnus spacecraft was released from the Canadarm2 robotic arm which earlier detached Cygnus from the Earth-facing port of the International Space Station’s Unity module. At the time of release, the station was flying about 260 miles over the Atlantic Ocean. The Cygnus spacecraft successfully departed the space station more …

Following commands from ground controllers at SpaceX in Hawthorne, California, Dragon undocked at 5:05 p.m. EST from the forward port of the station’s Harmony module. At the time of undocking the station was flying at an altitude about 260 miles southwest of Chile. After re-entering Earth’s atmosphere, the spacecraft will make a parachute-assisted splashdown off …

Live coverage of the departure of SpaceX’s Dragon cargo spacecraft from the International Space Station is underway on NASA Television, the agency’s website, and the NASA app. Following commands from ground controllers at SpaceX in Hawthorne, California, Dragon will undock at 5:05 p.m. EST from the forward port of the station’s Harmony module and fire …

Live coverage of the departure of Northrop Grumman’s Cygnus cargo spacecraft from the International Space Station is underway on NASA+ streaming, NASA Television, the agency’s website, and the NASA app, with its release from the robotic arm scheduled for 8:05 a.m. EST. Flight controllers on the ground sent commands earlier Friday morning for the space …

Payloads: Advanced Resistive Exercise Device-Kinematics (ARED-K):  The crew retrieved several Multi-Use Brackets (MUBs) needed for the ARED-K experiment session, currently planned for tomorrow. Resistive exercise is used as a countermeasure to musculoskeletal deconditioning in microgravity and currently ISS crews perform resistive exercise using ARED. However, a major unknown is the internal bone and muscle forces …

A SpaceX Dragon cargo spacecraft is targeting its undocking from the International Space Station for 5:05 p.m. EST today. The Expedition 70 crew finished packing Dragon on Wednesday with a variety of research samples and lab hardware for retrieval and analysis on Earth. The orbital residents now turn their attention to the departure of a …

Editor's Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process. In November 2023, NASA's James Webb Space Telescope observed a massive cluster of galaxies named MACS J0138.0-2155. Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 appears warped by …
