Evidence of recent volcanic activity on Mars shows that eruptions could have taken place within the past 50,000 years, a paper by Planetary Science Institute Research Scientist David Horvath says.
Most volcanism on the red planet occurred between 3 and 4 billion years ago, with smaller eruptions in isolated locales continuing perhaps as recently as 3 million years ago. But, until now, ther

The early-stage NASA concept could see robots hang wire mesh in a crater on the Moon's far side, creating a radio telescope to help probe the dawn of the universe. After years of development, the Lunar Crater Radio Telescope (LCRT) project has been awarded $500,000 to support additional work as it enters Phase II of NASA's Innovative Advanced Concepts (NIAC) program.

New observations and simulations show that jets of high-energy particles emitted from the central massive black hole in the brightest galaxy in galaxy clusters can be used to map the structure of invisible inter-cluster magnetic fields. These findings provide astronomers with a new tool for investigating previously unexplored aspects of clusters of galaxies.

NASA and Boeing are now targeting July 30 for an uncrewed test flight of the aerospace company's troubled Starliner capsule to the International Space Station, they announced Thursday.
The launch has been postponed multiple times, with the last announced date of April scuppered due to a cold snap that caused extensive power outages in Texas in March.
The NASA Commercial Crew program is run partly from the Johnson Space Center in Houston, though it launches from Cape Canaveral in Florida.
Lift-off is now scheduled for 2:53 pm Eastern Time (1853 GMT) on July 30.
"NASA and Boeing have done an incredible amount of work to get to this point," said Steve Stich, Commercial Crew program manager.
