NASA and ESA have signed a partnership agreement to get the ExoMars Rosalind Franklin rover down to the surface of Mars, getting the mission back on track after geopolitical factors delayed it.

Edward C. Stone, Caltech's David Morrisroe Professor of Physics, Emeritus, passed away on June 9 at the age of 88. Stone was a prominent figure in space physics and planetary astronomy, where he led numerous space missions and significantly advanced the field. He was also a cherished friend of The Planetary Society.

NASA's DART mission showed that if we detect a dangerous asteroid headed toward Earth, knocking it off course with a spacecraft is a potential option.

The Planetary Society is requesting proposals from individual contractors / organizations to provide design services to produce our quarterly space magazine.
