Salt Lake City, UT – Another round of hundreds more layoffs began this week at Utah aerospace company ATK. Many are because NASA's space shuttle program is winding to an end. This coming Monday, the Obama administration will release its 2011 budget for NASA. Workers who remain at ATK are anxiously awaiting one verdict whether astronauts will go back to the moon. It's not just thousands of high-tech jobs that are at stake - but the nation's ability to explore space. KUER's Jenny Brundin reports.
