Laser Ranging Confirms Moon’s Inch-by-Inch Retreat from Earth

Scientists confirm the Moon is slowly moving away from Earth at about 1.5 inches per year. Laser-ranging measurements to lunar mirrors show the average distance of roughly 239,000 miles, with small variations as the Moon’s orbit drifts outward due to tidal forces that transfer Earth's rotational energy to the Moon. This gradual recession has lengthened Earth’s days over billions of years and affects tides; in the long term it will reduce the frequency of total solar eclipses, with some estimates suggesting the last such eclipse could occur about 600 million years from now. The Moon formed around 4.5 billion years ago after a colossal impact, and its ongoing drift reflects the long-term evolution of the Earth–Moon system.

Live Flyby: House-Sized Asteroid 2026 JH2 Skims Past Earth

Asteroid 2026 JH2, roughly 14–30 meters across, will pass within about 57,000 miles (92,000 km) of Earth today—closer than a quarter of the Moon’s distance. It poses no threat, but scientists will use the Virtual Telescope Project 2.0 livestream to study its orbit and physical properties as it whizzes by, with closest approach around 5:58 p.m. ET. The rock completes an orbit around the Sun every 3.76 years; the next close pass won’t occur until 2090.

Artemis 2's lunar flyby yields a stunning 12,000-shot Earth timelapse

A new timelapse from NASA’s Artemis 2 archive showcases Earth in both day and night views, satellites, and auroras captured by the crew during their lunar flyby. The video compiles about 12,000 photos released from the mission, which launched April 1 and returned April 10 with four astronauts—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—marking the first crewed lunar flyby since Apollo 17. The footage highlights Earth from behind the Moon, including an ‘Earthset’ shot, and underscores Artemis’ broader plan to return humans to the Moon in upcoming missions Artemis 3 and 4.

Artemis 2 Captures: NASA Releases 12,000+ Moon-Earth Photos in New Gallery

NASA released a massive photo dump of over 12,000 images from Artemis 2, the first crewed lunar flyby, captured by astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen. Gizmodo spotlights photos of Earth from space, the Moon’s craters, a solar eclipse, and long-exposure star fields. The full dataset and preliminary mission reports are due in October and are already accessible on NASA’s Gateway to Astronaut Photography of Earth, which makes sorting through the gallery an immersive but lengthy task.

NASA Unveils 12,000 Artemis II Photos, From Moon Eclipses to Earthset Moments

NASA released 12,000 previously unseen Artemis II photos captured by the crew with Nikon D5, Nikon Z9 and an iPhone 17, including solar eclipse shots, Moon closeups, and Earthset images, plus candid in-cabin views. While some images are blurry or similar, the collection contains hidden gems and includes metadata; all images are accessible via NASA’s Gateway to Astronaut Photography of Earth site. Artemis II marks humans’ return to the Moon’s vicinity farther from Earth than ever before, making the photo trove a major record of the mission.

Mexico City's rapid subsidence mapped from orbit

NASA’s NISAR satellite measurements show Mexico City sinking unusually fast, with rates up to about 0.78 inches (2 cm) per month in areas like the airport and Angel of Independence, totaling roughly 9.5 inches (24 cm) per year and more than 12 meters across a century, highlighting a major geophysical challenge that space-based monitoring could help mitigate and guide adaptation.
