Dawn mission on the asteroid belt ends

WASHINGTON – A NASA spacecraft that has visited two of the largest objects in the Solar System’s main asteroid belt is running out of fuel, ending its mission, NASA said on November 1. NASA announced that the Dawn spacecraft was silent during two communications sessions on the Deep Space Network on October 31 and November […]

NASA’s Dawn mission to the asteroid belt says goodnight

NASA’s Dawn spacecraft, orbiting the asteroid Ceres, has died quietly, the space agency said Thursday. Dawn missed her scheduled recording on Wednesday. Mission officials concluded that the thruster on her thrusters was dry and Dawn could no longer control her orientation. Its antenna turned away from Earth and its radio signal was lost forever. It […]

NASA’s asteroid belt spacecraft Dawn is about to run out of fuel

NASA / JPL-Caltech / UCLA / MPS / DLR / IDA NASA’s Dawn spacecraft has been crossing the asteroid belt for nearly a decade. He discovered water on the giant asteroid Vesta and ice volcanoes on the surface of Ceres, the belt’s largest object. But now her time is coming to an end. Last year, […]

NASA’s Dawn mission to the asteroid belt is about to end

NASA launched an ion-powered probe called Dawn towards the asteroid belt in 2007. In 2015, Dawn reached Ceres, a dwarf planet the size of Texas that could hide a salty ocean and possibly alien life. The spacecraft is almost out of fuel and its mission could end between mid-September and mid-October. Researchers expect Dawn to […]

NASA to Host Live Chat on Successful Asteroid Belt Mission

NASA’s Jet Propulsion Laboratory in Pasadena, Calif., Will host a live science chat at 11:00 a.m. PDT (2:00 p.m. EDT) on Friday, September 7, during which experts will discuss the role of the Dawn spacecraft in the agency in the study of the beginning of our solar system and the near end of its 11-year […]

85% of the asteroid belt is made up of remnants of ancient planets

A new study from the University of Florida has found that 85 percent of our solar system’s asteroid belt between Mars and Jupiter is made up of the remains of five or six ancient little planets. The lead author of the recently published research paper, Stanley Dermott, argues that it is likely that the 15 […]
