Only Michael Griffin knows for sure. He’s the head of NASA, and he’s taken it upon himself to decide whether to send a shuttle mission to rescue the Hubble Space Telescope. Griffin isn’t talking until Tuesday morning. But NASA has called a news conference at the Goddard Space Flight Center in Maryland, where much of the work on the Hubble is done, when he could just as easily have gone downstairs from his office to the auditorium at NASA HQ in Washington. And they’re doing up new computer animation of the Hubble. And there’s a news conference later in Houston to announce the crew of the Hubble rescue mission, if Griffin decides to go ahead with it? Would they do all this if he’s decided NOT to go ahead? Gina Sunseri has written a preview; take a look HERE.
