After 11 years at Mars, NASA's MAVEN spacecraft went out with a whisper

4 June 2026 at 17:21

NASA's MAVEN spacecraft was in excellent shape when it disappeared behind Mars on December 6 of last year. The routine passage, called an occultation, was supposed to last less than an hour, but ground teams didn't hear from the spacecraft when it was supposed to regain contact with Earth.

The loss of communication triggered contingency plans for engineers to try to restore a link with MAVEN, which orbits Mars more than 200 million miles from Earth. To no avail, they listened for faint signals and uplinked commands in the blind. Hopes of saving the mission faded over time, and NASA officials announced Wednesday that they're giving up on it.

"NASA has ceased efforts to search for the MAVEN spacecraft and are beginning activities to decommission the mission," said Mike Moreau, MAVEN's project manager at NASA's Goddard Space Flight Center in Maryland.Β

What Happened to Earth’s Rings?

18 August 2025 at 04:15
The existence of evidence for Earth’s past equatorial ring, shown by impact craters, raises questions about its loss. Modeling its effects on Earth's rotation presents challenges. However, current findings indicate minor impacts on day length, with significant stability in the Earth-Moon system over 10,000 years.

If Jupiter Disappeared Would Earth Face More Asteroid Hits?

27 February 2026 at 13:56

Jupiter dominates the Solar System’s architecture. At about 318 times Earth’s mass and orbiting far beyond Mars, it acts as a gravitational gatekeeper, tugging on asteroids and comets that might otherwise stay put or never reach the inner planets. Remove Jupiter from the picture and Earth’s impact environment would change in complicated ways. It would […]

SpaceX's Starship V3β€”still a work in progressβ€”mostly successful on first flight

23 May 2026 at 18:54

SpaceX launched the first test flight of its upgraded Starship rocket and Super Heavy booster Friday, with mostly positive results.

The powerful rocket, propelled by 33 methane-fueled main engines, climbed away from SpaceX's Starbase launch facility in South Texas at 5:30 pm CDT (6:30 pm EDT; 22:30 UTC) Friday. Within a few seconds, the 408-foot-tall (124-meter) rocket, the largest ever built, cleared the launch tower and turned onto an eastward heading over the Gulf of Mexico.

Starship splashed down on target in the Indian Ocean a little more than an hour later to conclude the first flight of the latest version of SpaceX's stainless-steel mega-rocket. Starship V3 fared better on its debut than the first flights of Starship V1 and V2 in 2023 and 2025. Both past versions of Starship broke apart during launch on their inaugural flights.
