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.
Marc Rayman is chief engineer on NASA’s Dawn mission, which has run out of fuel after a 11-year interplanetary journey that explored Vesta and Ceres, the two largest objects in the asteroid belt between the orbits of Mars and Jupiter.
