U.S. Space Force’s X-37B Space Plane Takes a Selfie with Earth

Astronomy, Planetary Science /

Last week, the U.S. Space Force shared an image from the uncrewed X-37B space plane’s seventh mission, capturing the orbital test vehicle soaring above Earth in High Earth Orbit—a selfie worth showcasing. The 29-foot (8.8-meter) Boeing-built autonomous spacecraft reportedly used its onboard camera to take the photo while performing an aerobraking maneuver. This technique involves […]

SpaceX Says Starship Self-Destructed Due to Propellant Leaks, Fires, and a Comms Blackout

Astronomy, Planetary Science /

SpaceX revealed Monday that last month’s Starship explosion resulted from a chain reaction triggered by propellant leaks—a problem the company claims to have resolved ahead of a potential eighth test flight as early as Friday. The company is still awaiting FAA approval, either through the official closure of the “mishap investigation” or special authorization to

Fragments of Rock Uncover the Moment the Moon Became Solid

Astronomy, Planetary Science /

The early history of the Moon remains a topic of scientific investigation. Despite extensive knowledge about Earth’s natural satellite, some pieces of its history are still being unraveled. Recent studies of rock samples collected during the Apollo missions have provided new insights, revealing that the Moon solidified approximately 4.43 billion years ago—around the same time

Risk of 2032 Asteroid Impact Reduced: Key Details You Should Know

Astronomy, Astrophysics, Planetary Science /

Asteroid 2024 YR4 recently made headlines after NASA estimated a 1-in-32 chance of impact in 2032—the highest probability ever recorded for a hazardous-sized asteroid. Fortunately, new observations have since cut that risk in half. Discovered in late December, the asteroid passed Earth at roughly twice the Moon’s distance. Based on observations, its size is estimated

Hydrogel Absorbs Cosmic Rays to Shield Astronauts in Space

Astronomy, Planetary Science /

Hydrogel is commonly found in everyday items like contact lenses, burn dressings, and hair gel. In the future, it could also serve as a protective barrier against harmful cosmic radiation for astronauts on long-duration space missions. Radiation exposure is a significant risk in space travel. Beyond Earth’s atmosphere, astronauts aboard the International Space Station (ISS)

ESA’s Plan to Remove Space Debris Needs Global Collaboration

Astronomy, Planetary Geology /

The issue of space debris has been growing for years, exacerbated by the continuous launch of rockets and payloads. In recent years, organizations, particularly the European Space Agency (ESA), have begun to take the issue more seriously. Now, they are asking: How can we achieve zero space debris? The Scale and Danger of Space Debris
