Hubble Could Get a New Lease on Life—If NASA Can Afford It

NASA Weighs Hubble Reboost Mission, But Cost Remains Key Hurdle

Hubble is predicted to reenter Earth's atmosphere by 2033 due to orbital decay.
NASA is considering a reboost mission to extend Hubble's life, but only if operating costs can be reduced.
A similar rescue mission for the Swift telescope is underway, demonstrating lower-cost reboost technology.
NASA's astrophysics division director emphasized the need to lower Hubble's operational costs before committing to a reboost.

This one-legged robot could be NASA's key to exploring Enceladus' plumes

NASA’s LEAP Concept Imagines a One-Legged Robot for Enceladus

LEAP is a NASA-backed concept for a one-legged hopping robot on Enceladus.
The robot would stand about one foot tall and weigh roughly 2 pounds.
It would use a spring-driven leg, wheels and reaction wheels to move and self-right.
The concept targets plume-rich terrain on a moon considered a prime site in the search for life.

Why dust may be more important to the universe than it first appears

Universe Today argues that dust is both a serious engineering nuisance and a fundamental component of many cosmic processes.
The piece highlights health risks, explosive hazards, and the abrasive behavior of lunar dust encountered during Apollo missions.
The same material that disrupts missions and observations also helps explain why dust remains central to astronomy and planetary science.

The Moon, backlit by the Sun during a solar eclipse, is photographed by NASA’s Orion spacecraft on April 6, 2026, during the Artemis II mission. Orion is visible in the foreground on the left. Earth is reflecting sunlight at the left edge of the Moon, which is slightly brighter than the rest of the disk. The bright spot visible just below the Moon’s bottom right edge is Saturn. Beyond that, the bright spot at the right edge of the image is Mars.
