The Administrator, in consultation with the Director of the Office of Management and Budget, shall determine what balances from the “Mission support” account are to be transferred to the “Human space flight” and “Science, aeronautics and technology” accounts. Such balances shall be transferred and merged with the “Human space flight” and “Science, aeronautics and technology” accounts, and remain available for the period of which originally appropriated.
The unexpired balances of prior appropriations to the Administration for activities authorized under this chapter may be transferred to the new account established for such activity in subsection (a) of this section. Balances so transferred may be merged with funds in the newly established account and thereafter may be accounted for as one fund under the same terms and conditions.
