Chandrayaan-3 Moon Landing Successful: India has created history as it became the first country to land on the South Pole of lunar surface. PM Modi congratulated Indians and space scientists for the achievement. ‘India will remember this day forever’ PM Modi said. The real test of the mission began at the last leg of the landing. Prior to 20 minutes before landing, ISRO initiated Automatic Landing Sequence (ALS). It enabled Vikram LM to take charge and use its on-board computers and logic to identify a favourable spot and make a soft-landing on the lunar surface. Experts say that the final 15 to 20 minutes were highly crucial for the success of the mission when Chandrayaan-3's Vikram lander descended down to its soft landing. Indians throughout the country and across the world are prayed for Chandrayaan-3's Successful Landing today. Given the history of India's second lunar mission, which failed during the last 20 minutes before landing, ISRO was extra-cautious this time in the process. Due to high risk to the spacecraft minutes before moon landing, the duration is dubbed by many as "20 or 17 minutes of terror". During this phase, the whole process became autonomous, where Vikram lander ignited its own engines at the right times and altitudes.

This video 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.
