JAMES NEWTON, LEFT, PHILLIP THOMPSON, CENTER, AND DAVID LAWRENCE, RIGHT PREPARE COMPOSITE TOOL FOR CURE IN 18' X 20' AUTOCLAVE IN BUILDING 4707

The NASA Super Guppy arrived at Moffett Field on Jan. 7, 2016, carrying the Artemis I Orion heat shield skin. The heat shield is being primarily built at Lockheed Martin’s Littleton, Colo. facility, and it was temporarily sent to Lockheed Martin’s Sunnyvale, Calif. facility for an autoclave cure (shown here). The heat shield is a stiffened skin design, and this cure process is the last step prior to attaching titanium stiffeners to the interior surface. Once the skin and stiffeners are attached, ablative material is applied to the exterior. Part of Batch image transfer from Flickr.

STS50-262-004 (25 June-9 July 1992) --- Astronaut Kenneth D. Bowersox, STS-50 pilot, holds an autoclave used in the growing of zeolite crystals on the middeck of the Earth-orbiting Space Shuttle Columbia. He is standing near the Zeolite Crystal Growth (ZCG) furnace, which is housed in the space of two stowage lockers. On the 14-day U.S. Microgravity Laboratory mission, zeolite crystals were grown in 38 individual autoclaves, which were joined in pairs to be inserted into the 19 furnace orifices. While the autoclaves appear the same externally, there are several types of internal arrangements that were tested to determine which one provides the best mixing of the component solutions. The portrait of alternate payload specialist Albert Sacco, Jr. is mounted nearby. Sacco, serving as a ground controller at Marshall Space Flight Center in Alabama, worked in conjunction with the red shift crew in the science module.

jsc2024e067097 (10/15/2024) --- The Midlands Tech experimental flight team and faculty advisors prepare materials to be autoclaved for the next round of tests. Their experiment, Gravitational Effects on Calcium Oxalate (CaOx) Regulation in Edible Greens, is part of the Nanoracks-National Center for Earth and Space Science Education-Surveyor-Student Spaceflight Experiments Program Mission 18 to ISS (Nanoracks-NCESSE-Surveyor-SSEP).

Payload specialist Albert Sacco Jr. inspects a crystal in a cylindrical autoclave on the mid-deck of the earth-orbiting space shuttle Columbia. This Zeolite Crystal Growth (ZCG) experiment was one of a few U.S. Microgravity Laboratory (USML-2) experiments that were conducted in both the Shuttle proper and its primary cargo's science module in the payload bay. Most of the experiments were conducted solely in the science module. Sacco was one of two guest researchers who joined five NASA astronauts for 16 days of Earth-orbit.

ISS006-E-08784 (14 December 2002) --- View of a bubble formed as a result of a Zeolite Crystal Growth (ZCG) experiment in the Destiny laboratory on the International Space Station (ISS). Expedition Six Commander Kenneth D. Bowersox used a Space Station drill to mix 12 Zeolite samples in clear tubes. Scientists on the ground watching on TV noticed bubbles in the samples. Bowersox used a modified mixing procedure to process autoclaves to isolate bubbles. He re-inserted the samples in the ZCG furnace in Express Rack 2 in the U.S. laboratory/Destiny. This experiment has shown that the bubbles could cause larger number of smaller deformed crystals to grow. Bowersox rotated the samples so that the heavier fluid was thrown to the outside while the lighter bubbles stayed on the inside.

Engineers at Marshall Space Flight Center (MSFC) in Huntsville, Alabama, are working with industry partners to develop a new generation of more cost-efficient space vehicles. Lightweight fuel tanks and components under development will be the critical elements in tomorrow's reusable launch vehicles and will tremendously curb the costs of getting to space. In this photo, Tom DeLay, a materials processes engineer for MSFC, uses a new graphite epoxy technology to create lightweight cryogenic fuel lines for futuristic reusable launch vehicles. He is wrapping a water-soluble mandrel, or mold, with a graphite fabric coated with an epoxy resin. Once wrapped, the pipe will be vacuum-bagged and autoclave-cured. The disposable mold will be removed to reveal a thin-walled fuel line. In addition to being much lighter and stronger than metal, this material won't expand or contract as much in the extreme temperatures encountered by launch vehicles.
