NASA is developing the most advanced man-rated rocket and spacecraft to enable human exploration farther into space than we have ever traveled before
The Space Launch System (SLS) is the American heavy lift launch vehicle and is part of NASA‘s deep space exploration plans. The SLS rocket will carry astronauts and cargo aboard NASA’s spacecraft to the Moon and to other intermediary locations in space, where astronauts will build and begin testing the systems needed for challenging missions to other planetary and interplanetary destinations, including Mars, and deeper into space.
Boeing Aerospace manages the prime contract for the design of the SLS Core Stage (CS), the Enhanced Upper Stage (EUS), and integration of the overall vehicle. Geocent has supported Boeing/NASA since the beginning of this program and has been rated as a Gold or Silver supplier every quarter/year and has twice received Boeing’s Supplier Advocacy Award.
The challenge of deep space exploration is unlike any challenge in human history. Not only must the systems carry humans and equipment beyond Low Earth Orbit (LEO), something not accomplished since the Apollo missions, they must support lunar decent and ascent, potential permanent lunar habitation, a deep-space gateway, a radiation-shielded vehicle to carry humans on the long journey to and from Mars, and both decent and ascent from the Martian surface. No such scientific and engineering operation has ever been undertaken in human history. Additionally, challenges to the physical and mental health of the astronauts will be of paramount concern for long duration space flight.
Geocent placed highly skilled professionals and Subject Matter Experts (SMEs) throughout Boeing Huntsville and the Michoud Assembly Facility (MAF) to support Boeing in the design, analysis, manufacture, testing and certification of the SLS Core Stage (CS) and Enhanced Upper Stage (EUS).
