Data from NASA’s Dawn reveals chemical energy source on Ceres
Using data from NASA’s now-retired Dawn spacecraft, scientists have found that Ceres, a dwarf planet and the largest object in the asteroid belt, may have once had a lasting source of chemical energy. The Dawn data revealed evidence of molecules needed to fuel microbial metabolisms on Ceres. While the finding doesn’t confirm that microorganisms existed…

Polaris aiming to break barriers, build experience with Polaris Dawn
One of the most highly anticipated missions in 2024 is now mere days away from taking flight. The Polaris Dawn mission, scheduled to launch on SpaceX’s Falcon 9 and Crew Dragon with a four-person complement no earlier than Monday, Aug. 26, will see the introduction of new technologies and many records eclipsed — setting a…

Dawn, the intrepid explorer of multiple worlds
As another spacecraft prepares to land on Mars, the Dawn spacecraft recently ended its mission to explore two of the largest worlds in the asteroid belt and it has succeeded well beyond expectations, starting a new era in the exploration of the Solar System’s small worlds. As the age of robotic planetary exploration began, as…

NASA’s Dawn spacecraft runs out of fuel in the asteroid belt
NASA’s Dawn spacecraft ran out of fuel Wednesday and stopped transmitting to Earth, ending an 11-year mission that explored the two largest objects in the asteroid belt and set several records in the annals of space history. Dawn failed to contact controllers at NASA’s Jet Propulsion Laboratory in California during an overnight communications opportunity late…

Dawn mission managers await NASA decision on spacecraft’s future
Artist’s concept of the Dawn spacecraft with one of its ion engines firing. Credit: NASA/JPL-Caltech The future of NASA’s Dawn spacecraft, running low on hydrazine fuel and now flying around the dwarf planet Ceres without the help of internal pointing wheels, will be decided in the coming weeks by top space agency managers. Scientists have…

YIR III: From dwarfs to giants – the missions of Dawn, Juno, and Cassini
Moving out into the asteroid belt and farther still to the gas giants, NASA’s Dawn, Juno, and Cassini missions churned away in orbit of their respective hosts – with Dawn continuing an up-close-and-personal investigation of the dwarf planet Ceres, Juno’s fantastically accurate arrival at Jupiter but frustratingly crippled start to its science mission, and the…
