NASA and SpaceX have rescheduled the undocking of the Dragon cargo capsule from the ISS to May 23 due to adverse weather. Part of the CRS-32 mission, the Dragon will return scientific experiments and supplies to Earth. The mission delivered 6,700 pounds of cargo to the ISS. NASA will livestream the undocking, but the splashdown will not be webcast.

The deep ocean, covering most of Earth, remains largely unexplored, with only 0.001% visually studied. It regulates climate, harbors unique ecosystems, and holds potential resources. However, human activities like climate change, pollution, and overfishing threaten this vital environment before its true value is understood, necessitating urgent conservation efforts and sustainable practices.
A vibrant blue poison dart frog, *Ranitomeya aetherea*, has been identified as a new species in the western Amazon. Discovered near the Juruá River, this frog boasts striking copper highlights on its limbs and distinctive pale blue stripes. Its unique call patterns and specific habitat preferences make it a significant find, highlighting the vulnerability of such species to environmental changes.
A large asteroid, 2003 MH4, will pass by Earth on May 24. It is about the size of the Eiffel Tower. The asteroid will travel at 30,060 kilometers per hour. NASA considers this a close encounter. Continuous monitoring of near-Earth objects is important. Even small gravitational changes can alter an asteroid's path.
SpaceX's Starship rocket exploded during a test. The issue was a fuel reaction in an engine. The company made fixes, including better insulation. The Federal Aviation Administration approved the changes. A new test flight is set for May 27. This flight will reuse a Super Heavy booster. SpaceX aims to use Starship for Moon and Mars missions.
Asteroid 2003 MH4, a large space rock about three football fields in length, will make a close approach to Earth around May 24, 2025. While not an immediate threat, its size and speed have prompted NASA to closely monitor its trajectory. This event highlights the importance of ongoing planetary defense efforts and the need for vigilance in tracking near-Earth objects.
Group Captain Shubhanshu Shukla is preparing for the Axiom-4 mission to the ISS, now launching no sooner than June 8, 2025. This joint ISRO, NASA, and ESA mission marks a significant step for India's space program. Shukla will conduct experiments, including space agriculture research, and engage with Indian students via live broadcast.
Researchers propose a lunar space elevator using existing materials, potentially revolutionizing space travel within decades. Anchored on the moon and extending to Earth's orbit, this "spaceline" could drastically cut mission costs and fuel needs. It would also enable a sustainable human presence in space, facilitating lunar bases and interplanetary missions.
Scientists are using satellite data to monitor tree health near volcanoes. Trees absorb volcanic carbon dioxide, which makes them greener. NASA's AVUELO project and other satellites track these changes. This helps detect early signs of volcanic activity. The goal is to improve volcano early warning systems, especially in remote areas. Ground observations are crucial for verifying satellite data.
New research challenges the long-held belief that asteroid Vesta is a protoplanet. Scientists at Michigan State University suggest Vesta is a fragment of a larger, extinct planet shattered in a massive collision 4.5 billion years ago. Gravity data from NASA's Dawn mission reveals no metal-rich core, contradicting earlier assumptions and redefining planetary evolution.
