![]() The defense contractor is building the rocket’s core stage, which provides most of the vehicle’s propulsion beyond Earth’s atmosphere. ![]() Responsible for several components, Boeing is the primary contractor for the SLS. These SRBs produce most of the Space Launch System’s propulsion, with each producing 3.3 million pounds of thrust. When the old SRBs run out, the defense contractor will start building new ones. The company regularly runs static fire tests to confirm its usability. To maintain these old SRBs, NASA hired Northrop Grumman Space Systems. The SLS will use two five-segment solid rocket boosters, some of which are remnants from the Space Shuttle program canceled in 2011. SLS comes equipped with 4 of them, each producing over 400,000 pounds of force. ![]() Now, as NASA prepares for the Artemis era, the defense contractor returns with modified RS-25 rocket engines. The company built the J-2 and HG-3 engines that were used in the Saturn family of rockets during the Apollo era. When NASA needs propulsion technology, they typically contract Aerojet Rocketdyne. Aerojet Rocketdyne A rocket must obtain thrust from a rocket engine in order to launch. The Space Launch System (SLS) is included, and for that, NASA hired several companies to build different components. For everything from the Delta family of rockets to the iconic Saturn V, the government space agency hires contractors. The simple and straight answer is, NASA does not build its own launch vehicles.

Quick Facts Year Founded 1958 Founders Dwight D. Continue reading for everything you need to know about the latest space launch vehicle. The Space Launch System is the biggest and most powerful rocket the organization has ever had. With contracted help from the country’s most prominent defense contractors, NASA would design a rocket that would outclass even the historic Saturn V. Private companies such as SpaceX and Blue Origin went to work designing rockets that could support the program, but NASA would build a rocket of its own. NASA formally announced the Artemis program in 2017, with the aim of sending humans back to the moon. Boeing is also responsible for several components connected to NASA launches.When NASA needs propulsion technology, they typically contract Aerojet Rocketdyne.NASA does not build its own launch vehicles.
