Q&A with Scott Bolton, principal investigator on NASA’s Juno mission

The next launch of United Launch Alliance’s Atlas 5 rocket with the U.S. Air Force’s fifth Advanced Extremely High Frequency communications satellite, previously scheduled for Thursday, has been delayed to no earlier than July 12 to replace a failed battery on the vehicle.

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.

Just before settling to a soft crash landing Friday, the European Space Agency’s Rosetta spacecraft captured close-range images of comet 67P/Churyumov-Gerasimenko, peering into a stadium-sized pit and recording a final dataset to keep scientists busy long after the mission’s end.
