NASA awarded space shuttle operator United Space Alliance (USA) a $232.9 million contract modification covering program closeout activities, the agency announced Nov. 18.

The modification to the Space Program Operations Contract, a cost-plus-award-fee-reimbursement contract, provides funds for USA to prepare the retired space shuttle orbiters for public display, and to cover closeout costs for 31 space shuttle subcontractors.

Besides preparing the orbiters for display, the funds will go toward property disposal and record keeping, NASA said. The space shuttle program flew its final mission in late July.
