Twenty-seven members of the U.S. House of Representatives are warning NASA Administrator Charles Bolden not to shut down any part of the Constellation program this year, citing a provision included in a 2010 omnibus spending bill that bars the agency from terminating any part of the space shuttle replacement effort without formal congressional approval.

โ€œWe have become aware of the formation by NASA Headquarters of at least five โ€˜tiger teams,โ€™ the job of which is to shut down Constellation and transition to the new program,โ€ states a Feb. 12 letter to Bolden spearheaded by Rep. Pete Olson (R-Texas) and signed by 20 other Republicans and fiveDemocrats.

The letter also instructs Bolden to reinstate an unspecified โ€œmajor contract related to Ares 1โ€ that was put on hold Jan. 23, adding that any disruption to Constellation contracts will be viewed as a program termination.
