Live coverage: Rosetta’s final hours

NASA has terminated a $97 million contract with OrbitBeyond, a New Jersey-based company with plans to build robotic moon landers in Florida, just two months after announcing an agreement to send science instruments to the lunar surface as soon as next year.

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.

Within days, NASA is expected to select a winner from a roster of nine eligible companies to try and become the first commercial entity to accomplish a soft landing on the moon with a robotic spacecraft. The privately-developed probe would be the vanguard in a series of unpiloted missions intended to deliver science instruments to the lunar surface and prepare for a human expedition as soon as 2024.
