The Marshall Space Flight Center (MSFC) and the Johnson Space Center (JSC) were each awarded 16-month contracts in April 1976 for the Space Station Systems Analysis Study (SSSAS). Grumman Aerospace Corporation was MSFC's contractor and McDornell Douglas Aerospace Company was JSC's contractor. The goal of this study was to formulate plans for a permanent operational base and laboratory facility in Earth orbit in addition to developing a space construction base design for implementing the program. An expended Space Shuttle external tank was to be the central core platform of the base, and additional pressurized modules could be added to provide laboratory facilities. This artist's concept depicts a space construction base design for implementing the SSSAS.

Epithelial cell monoculture: Long-term growth of human mammary epithelial cells (HMEC) grown in monoculture as 3-dimensional constructions in the presence of attachment beads in the NASA Bioreactor. A: A typical construct about 3.5 mm (less than 1/8th inch) in diameter with slightly dehydrted, crinkled beads contained on the surface as well as within the 3-dimensional structure. B: The center of these constructs is hollow. Crinkling of the beads causes a few to fall out, leaving crater-like impressiions in the construct. The central impression shows a small hole that accesses the hollow center of the construct. C: A closeup view of the cells and the hole the central impression. D: Closer views of cells in the construct showing sell-to-cell interactions. NASA's Marshall Space Flight Center (MSFC) is sponsoring research with Bioreactors, rotating wall vessels designed to grow tissue samples in space, to understand how breast cancer works. This ground-based work studies the growth and assembly of human mammary epithelial cell (HMEC) from breast cancer susceptible tissue. Radiation can make the cells cancerous, thus allowing better comparisons of healthy vs. tunorous tissue. Credit: Dr. Robert Richmond, NASA/Marshall Space Flight Center (MSFC).

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, the seventh tower segment of a new mobile launcher, or ML, being constructed to support the Constellation Program, is hoisted by crane toward the six segments already secured to the launcher's surface. When completed, the tower will be approximately 345 feet tall and have multiple platforms for personnel access. The construction is under way at the mobile launcher park site area north of Kennedy's Vehicle Assembly Building. The launcher will provide a base to launch the Ares I rocket, designed to transport the Orion crew exploration vehicle, its crew and cargo to low Earth orbit. Its base is being made lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the heavier load of the tower and taller rocket.

The base of the launcher is lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the heavier load of the tower and a taller rocket.

iss073e0606894 (Sept. 5, 2025) --- JAXA (Japan Aerospace Exploration Agency) astronaut and Expedition 73 Flight Engineer Kimiya Yui works on the Maturation of Vascularized Liver Tissue Construct in Zero Gravity (MVP Cell-07) investigation aboard the International Space Station. The experiment examines how bioprinted or engineered liver tissue constructs containing blood vessels printed on Earth develop in a microgravity environment. This research aims to advance space-based tissue production, potentially ensuring astronaut health on future missions and improving treatments for patients on Earth.

The S-IC-T stage (static firing stage) is installed and awaits the first static firing of all five F-1 engines at the Marshall Space Flight Center S-IC static test stand. Constructed in 1964, the S-IC static test stand was designed and constructed to develop and test the first stage of the Saturn V launch vehicle that used five F-1 engines. Each F-1 engine developed 1,500,000 pounds of thrust for a total liftoff thrust of 7,500,000 pounds. To handle this research and development effort, the stand contains 12,000,000 pounds of concrete on its base legs that are planted down to bedrock 40 feet below ground level. Of concrete and steel construction, the stand foundation walls are 4 feet thick, and topped by a crane with a 135-foot boom. With the boom in the up position, the stand is given an overall height of 405 feet, placing it among the highest structures in Alabama at the time.

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, a new mobile launcher is under construction for the Constellation Program. The new mobile launcher will be the base for the Ares rockets to launch the Orion crew exploration vehicle and the cargo vehicle. The base is being made lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the added load of the 345-foot tower and taller rocket. When the structural portion of the new launcher is complete, umbilicals, access arms, communications equipment and command/control equipment will be installed. Photo credit: NASA/Jim Grossmann

Members of the Southeast U.S. Federal Laboratory Consortium for Technology Transfer gather at the base of the B-1/B-2 Test Stand during a Feb. 10 visit to John C. Stennis Space Center. The group visited Stennis to tour facilities and receive briefings on work at the rocket engine test site. They also visited the INFINITY at NASA Stennis Space Center site and received a briefing on construction of the new science center. The FLC is a nationwide network of federal laboratories to facilitate technology transfers between federal agencies and commercial companies.

KENNEDY SPACE CENTER, FLA. - On June 8, the base for a C-band radar antenna is being constructed at a radar site on North Merritt Island, Fla. The 50-foot C-band radar will be used for long-term Shuttle missions to track the launches and observe possible debris coming from the Shuttle. The launch window for the first Return to Flight mission, STS-114, is July 13 to July 31.

Marshall Space Flight Center's F-1 Engine Test Stand is shown in this picture. Constructed in 1963, the test stand is a vertical engine firing test stand, 239 feet in elevation and 4,600 square feet in area at the base, and was designed to assist in the development of the F-1 Engine. Capability is provided for static firing of 1.5 million pounds of thrust using liquid oxygen and kerosene. The foundation of the stand is keyed into the bedrock approximately 40 feet below grade.
