Life In Asteroid Belt? New Research Suggests Ceres Was Once Habitable
A new study based on data from NASA's Dawn mission suggests that Ceres, the largest object in the asteroid belt, may have been capable of supporting single-celled life billions of years ago.

Asteroid Vesta May Be a Fragment of a Lost Planet, Say Scientists
Vesta, once believed to be a stalled protoplanet, may be a fragment of a long-lost differentiated planet. Using refined gravity data from NASA’s Dawn mission, scientists found it lacks a dense core, suggesting it was ejected during a primordial impact. This revised view may apply to other asteroids and reshape planetary formation theories.

NASA's Dawn Mission Unveils Insights into Vesta’s Mysterious Gullies Using Lab Simulations
NASA’s Dawn mission to the asteroid Vesta revealed mysterious gullies on its surface. New lab experiments, simulating Vesta's harsh vacuum conditions, suggest that liquid water, possibly briny, could have flowed briefly and carved these channels. These findings challenge existing theories about liquid stability on airless bodies and provide insig...

Dwarf Planet Ceres Once Hosted a Muddy Ocean Below Its Icy Surface
Recent research indicates that Ceres, the largest object in the asteroid belt, likely harboured a muddy ocean beneath its icy crust. Advanced computer simulations suggest that its surface features and gravity measurements point to a past rich in ice. With its proximity to Earth, Ceres presents a promising target for further exploration, making it t...

SpaceX Polaris Crewed Mission Delayed After Leak in Ground Equipment
SpaceX's Polaris Dawn mission will be delayed by at least a day because of a helium leak in ground equipment at Kennedy Space Center, SpaceX has said. The highlight of the five-day mission is expected to come two days after launch, when the crew embarks on a 20-minute spacewalk 434 miles (700 km) from earth, in history's first such private spacewal...

Elon Musk Led SpaceX's Historic Polaris Launch Delayed After Helium Leak
SpaceX on Monday pushed back the historic launch of an all-civilian crew on an orbital expedition set to mark a new chapter in space exploration with the first spacewalk by private citizens.

NASA Probe Maps Ceres Craters Where Ice Can Accumulate
Scientists with NASA's Dawn mission have identified, on the dwarf planet Ceres, permanently shadowed regions most of which likely have been cold enough to trap water ice for a billion years.
