[Yahoo] Mark Sirangelo, named six weeks ago as special assistant to NASA Administrator Jim Bridenstine, left the agency as NASA abandoned a reorganization plan due to a chilly reception on Capitol Hill, Bridenstine said in a statement.
Two individuals close to the space program and familiar with the situation said Sirangelo was escorted out of NASA's headquarters in Washington on Wednesday after his resignation.
His departure came after lawmakers rejected NASA's proposal to create a separate directorate within the space agency to oversee future lunar missions and ultimately develop human exploration of Mars. |
