NASA missions bid for extensions, Nature
“… like six other ongoing NASA missions studying the Moon, Mars and Saturn, Opportunity’s money is due to run out at the end of the US fiscal year, on 30 September. Managers for each mission are trying to convince the agency to cough up continued funding, and their arguments are due on 11 April. A ‘senior review’ panel of external planetary scientists will rank the proposals’ potential science return, and submit their suggestions to NASA headquarters for a final decision.”
