WASHINGTON (NASA PR) — NASA’s Small Business Technology Transfer (STTR) program has awarded $15 million to U.S. small businesses and research institutions to continue developing technologies in areas ranging from aeronautics to science and space exploration.
HUNTSVILLE, Ala. (NASA PR) — As teams continue to prepare NASA’s Space Launch System (SLS) rocket for its debut flight with the launch of Artemis I, NASA and its partners across the country have made great progress building the rocket for Artemis II, the first crewed Artemis mission. The team is also manufacturing and testing major parts for Artemis missions III, IV and V.
WASHINGTON (NASA PR) — In 2021, NASA completed its busiest year of development yet in low-Earth orbit, made history on Mars, continued to make progress on its Artemis plans for the Moon, tested new technologies for a supersonic aircraft, finalized launch preparations for the next-generation space telescope, and much more – all while safely operating during a pandemic and welcoming new leadership under the Biden-Harris Administration.
KENNEDY SPACE CENTER, Fla. (NASA PR) — NASA’s Space Launch System (SLS) rocket and Orion spacecraft are undergoing integrated testing inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida to ensure they are “go” for launch of the Artemis I mission early next year.
STENNIS SPACE CENTER, Miss., Sept. 30, 2021 (Aerojet Rocketdyne PR) – Today’s RS-25 engine test at NASA’s Stennis Space Center completed the Retrofit-2 test series, which validated modernized, lower-cost components for new RS-25 engines to be used on the Space Launch System (SLS) heavy-lift rocket.
BAY ST. LOUIS, Miss. (NASA PR) — When Virgin Orbit, a satellite-launch company based in California, sought to expand its horizons, it was only natural for the company to think about NASA’s largest rocket engine test site – Stennis Space Center near Bay St. Louis, Mississippi.
NASA’s Space Launch System (SLS) core stage for the Artemis I mission arrived on April 27, 2021, at the agency’s Kennedy Space Center in Florida. The core stage arrived aboard the Pegasus barge from NASA’s Stennis Space Center in Mississippi to Kennedy’s Launch Complex 39 turn basin wharf.
The core stage is shown being transported into the iconic Vehicle Assembly Building on a self-propelled module transporter on April 29, 2021. Teams from the center’s Exploration Ground Systems and contractor Jacobs will perform checkouts ahead of integrating the massive rocket stage with the twin solid rocket boosters, Orion spacecraft, and additional flight hardware ahead of the Artemis I launch.
Artemis I will be the first integrated test of SLS and Orion and will pave the way for landing the first woman and first person of color on the lunar surface. It will be a proving ground for deep space exploration, leading the agency’s efforts under the Artemis program for a sustainable presence on the Moon and preparing for human missions to Mars.
BAY ST. LOUIS, Miss. (NASA PR) — The first core stage of NASA’s Space Launch System (SLS) rocket departs Stennis Space Center near Bay St. Louis, Mississippi, following completion of the Green Run series of tests of its design and systems. The stage now is in route to the agency’s Kennedy Space Center in Florida, its final stop prior to NASA’s launch of the Artemis I mission around the Moon. At Kennedy, the core stage will be integrated with the rest of the SLS rocket and the Orion spacecraft in preparation for launch. Through the Artemis program, NASA will return humans, including the first woman and first person of color, to the Moon and prepare for eventual journeys to Mars.

NASA to accept delivery of rocket stage to prepare for transport to Kennedy Space Center for integration and launch
STENNIS SPACE CENTER, Mississippi, April 21, 2021 (Boeing PR) — Boeing [NYSE: BA] begins delivery of the Space Launch System (SLS) rocket cryogenic core stage to NASA today in preparation for launch of the Artemis I mission, the first moon mission in nearly 50 years.
STENNIS SPACE CENTER, Miss. (Aerojet Rocketdyne PR) — Today (April 12), the world’s most powerful hydrogen-fueled rocket engine built by Aerojet Rocketdyne, the RS-68A, completed its final hot-fire acceptance test for use on the United Launch Alliance (ULA) Delta IV Heavy launch vehicle on the B-1 Test Stand at NASA’s Stennis Space Center in Mississippi.
BAY ST. LOUIS, Miss. (NASA PR) — NASA conducted a second RS-25 single engine hot fire test April 6 as part of a new series to support the development and production of engines for the agency’s Space Launch System (SLS) rocket on future missions to the Moon.
The full-duration hot fire of more than eight minutes (500 seconds) was conducted on the A-1 Test Stand at NASA’s Stennis Space Center near Bay St. Louis. It is part of a scheduled seven-test series designed to provide valuable data for Aerojet Rocketdyne, lead contractor for the SLS engines, as it begins production of new RS-25 engines for use after the first four SLS flights.
STENNIS SPACE CENTER, Mississippi, March 18, 2021 (Boeing PR) — Deep space exploration took an important step forward today. The cryogenic core stage for NASA’s Space Launch System (SLS) rocket completed hot fire testing at NASA’s Stennis Space Center as part of the SLS rocket’s Green Run test campaign on the B-2 test stand. The test, which included a full-duration, eight-minute engine burn, demonstrated successful core stage operation and will be used to help certify the stage for flight.
“I want to thank the extraordinary individuals who make up the NASA, Aerojet Rocketdyne and Boeing teams who designed, developed, produced and tested the all-new SLS core stage to enable sustainable human exploration of deep space,” said John Shannon, Boeing SLS vice president and program manager.
BAY ST. LOUIS, Miss. (NASA PR) — The largest rocket element NASA has ever built, the core stage of NASA’s Space Launch System (SLS) rocket, fired its four RS-25 engines for 8 minutes and 19 seconds Thursday at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The successful test, known as a hot fire, is a critical milestone ahead of the agency’s Artemis I mission, which will send an uncrewed Orion spacecraft on a test flight around the Moon and back to Earth, paving the way for future Artemis missions with astronauts.
BAY ST. LOUIS, Miss. (NASA PR) — Teams from NASA’s Space Launch System (SLS) Program conducted a successful full-duration 8 minute (499.6 seconds) hot fire of the Artemis I core stage on Thursday, Mar. 18 at NASA’s Stennis Space Center near Bay St. Louis, Mississippi on the historic B-2 Test Stand.
The hot fire got underway at around 4:40 p.m. EDT with all four RS-25 engines ignited successfully and produced 1.6 million pounds of thrust, as they will to launch the Artemis I mission to the Moon. During the test the engines consumed more than 700,000 gallons of liquid oxygen and liquid hydrogen propellant. The test was conducted with the core stage that will launch that first Artemis mission. Engineers collect data on how the stage behaved during critical operations, such as throttling the engines up and down and moving the engines dynamically in a variety of patterns. In coming days, engineers will scrutinize the data and determine if the stage is ready to be delivered to NASA’s Kennedy Space Center in Florida where it will be integrated with the twin solid rocket boosters already stacked in the Vehicle Assembly Building.
