NASA spacesuit prime vendor Hamilton Sunstrand secured a contract worth up to $728.9 million to continue mission support for extra-vehicular activities involving the space shuttle and international space station through 2015, NASA announced Sept. 30.

The deal includes a base contract worth $315.5 million to keep the spacesuits ready aboard the space shuttle and space station for use during spacewalks between Oct. 1, 2010, and Sept. 30, 2015. It also exercises a one-year option worth $8.6 million to support space shuttle extravehicular activities beginning Oct. 1, with two one-year options available through Sept. 30, 2012, if NASA is directed to continue flying the aging orbiters beyond their planned retirement next year. Five one-year options are also available for space station work between Oct. 1, 2015, and Sept. 30, 2020.

In addition, Hamilton Sunstrand garnered an indefinite-quantity, indefinite-delivery contract worth up to $90 million and a $140,000 fixed-price contract covering a 30-day phase-in period, the release states.
