China’s DRO-A/B Satellites Successfully Rescued After 123 Days Off Course
China’s DRO-A/B satellites suffered a launch anomaly in March 2024, missing their intended orbit. After 123 days, a young research team, including students who wrote 20,000 lines of code, successfully stabilized and maneuvered the satellites into the Distant Retrograde Orbit (DRO). The mission marks a major milestone in deep space exploration and satellite recovery.
Astronomers are closely monitoring interstellar comet 3I/ATLAS, only the third such object ever observed. Currently 670 million km from the Sun, it will approach closest in October 2025. Experts highlight its “absolutely foreign nature” and the unique insights it offers into other planetary systems. “Spotting a possible interstellar object is incredibly rare,” said Professor John Tonry.
NASA Astronaut Captures Rare Red Sprite Phenomenon from ISS
NASA astronaut Nichole Ayers, aboard the ISS as SpaceX Crew-10 pilot, photographed a rare red sprite—a transient luminous event—above thunderstorms on July 3, 2025. “Just. Wow … I caught this sprite,” Ayers shared. Such images help scientists study the formation and characteristics of TLEs (transient luminous events) and their link to thunderstorms.
NASA astronaut Nichole Ayers photographed a rare red sprite—a type of Transient Luminous Event (TLE)—from the International Space Station above a storm in Mexico. Ayers explained, “Sprites are TLEs… triggered by intense electrical activity in the thunderstorms below.” This image highlights the unique vantage point ISS provides for observing Earth’s atmospheric phenomena.
