Watch live as the Dragon Freedom spacecraft undocks with the four crew members of NASA’s SpaceX Crew-4 mission aboard: NASA astronauts Kjell Lindgren, Bob Hines, and Jessica Watkins, as well as ESA (European Space Agency) astronaut Samantha Cristoforetti. Undocking from the International Space Station (ISS) is targeted for Friday, Oct. 14. Splashdown is targeted several hours later at 4:55 p.m. EDT (2055 UTC) Friday off the coast of Florida. During their stay of nearly six months on the ISS

The DART mission deployed a kinetic impactor to smack the small moon Dimorphos of the asteroid Didymos on the evening of Sept. 26. This was an on-orbit demonstration of asteroid deflection, a key test of NASA's kinetic impactor technology, designed to impact an asteroid to adjust its speed and path. This particular asteroid moon is NOT a threat to Earth, but is technology being explored to use for when we DO find a potentially hazardous asteroid. The Hubble Space Telescope captured these extraordinary views of the asteroid moon soon after the successful impact

The astronauts of Crew-4 have undocked from the International Space Station and are on their way home to Earth. Watch live with NASA as the Dragon spacecraft Freedom reenters the atmosphere and splashes down off the coast of Florida. Splashdown is targeted for 4:55 p.m. EDT (2055 UTC), Friday, Oct. 14. NASA astronauts Kjell Lindgren, Jessica Watkins, Bob Hines, and ESA (European Space Agency) astronaut Samantha Cristoforetti spent five and a half months living and working aboard the orbiting laboratory. During their stay, they contributed to a number of experiments to expand our understanding of space while benefitting life on Earth

chronicles solar activity from Aug. 12 to Dec. 22, 2022, as captured by NASA’s Solar Dynamics Observatory (SDO). From its orbit in space around Earth, SDO has steadily imaged the Sun in 4K x 4K resolution for nearly 13 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system. With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 133-day time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme-ultraviolet wavelength that shows the Sun’s outermost atmospheric layer: the corona. Compiling images taken 108 seconds apart, the movie condenses 133 days, or about four months, of solar observations into 59 minutes. The video shows bright active regions passing across the face of the Sun as it rotates. The Sun rotates approximately once every 27 days. The loops extending above the bright regions are magnetic fields that have trapped hot, glowing plasma. These bright regions are also the source of solar flares, which appear as bright flashes as magnetic fields snap together in a process called magnetic reconnection. While SDO has kept an unblinking eye pointed toward the Sun, there have been a few moments it missed. Some of the dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. Other blackouts are caused by instrumentation being down or data errors. SDO transmits 1.4 terabytes of data to the ground every day. The images where the Sun is off-center were observed when SDO was calibrating its instruments. SDO and other NASA missions will continue to watch our Sun in the years to come, providing further insights about our place in space and information to keep our astronauts and assets safe.

Video Description: On the left side of the frame is the full circle of the Sun. It appears in a golden yellow color, but splotchy and with thin yellow wisps extending from the surface. Some areas are very bright and others almost black. The whole Sun rotates steadily, with one full rotation taking 12 minutes in this time lapse. There are usually only a few bright regions visible at a time and they shift and flash like small fires. From these regions there are wispy loops reaching up above the surface that rapidly change shape and size. On the right side of the frame are two white-outlined squares with enlargements of interesting regions of the Sun
