Nasa has awarded two contracts to US-based companies General Atomics and Precision Mechanical in a deal worth $98.8m.

Precision Mechanical has secured a firm fixed-price contract, with a total potential value of $60.3m, for the production, fabrication and installation of upgrades to the Liquid Hydrogen (LH2) System at Launch Complex 39B at Nasa’s Kennedy Space Center in Florida.

The modification and modernisation of the LH2 system includes the installation of a new LH2 storage sphere with a minimum capacity of 1.25 million gallons.

The project scope includes the integration of associated vaporisers, a flare stack and propane system, fill manifold, piping, valves, and controls.

Launch Complex 39B, a rocket launch site at the John F. Kennedy Space Center, is currently undergoing a complete refurbishment.

“Once completed, the facility will help support Nasa’s Space Launch System (SLS) rocket and Orion spacecraft for their first integrated uncrewed flight test.”

The other contract, with General Atomics based in San Diego, California, will include the delivery of necessary services to host the space agency’s Multi-Angle Imager for Aerosols (MAIA) instrument on a commercial satellite in low-Earth orbit.
