This is a close-up of an exact replica of the Apollo-era Lunar Roving Vehicle Wheel, of which twelve originals still rest on the surface of the Moon. The tire was designed to flex under load, without air, and was formed from a mesh of plated piano wire. Metal straps were hand riveted onto the mesh to reduce sinking into loose lunar soils. These replica wheels were tested in NASA Glenn's SLOPE Lab to establish a baseline for future improvements.

Created from a 1/16th model of a German World War II tank, the TAV (Tire Assault Vehicle) was an important safety feature for the Convair 990 Landing System Research Aircraft, which tested space shuttle tires. It was imperative to know the extreme conditions the shuttle tires could tolerate at landing without putting the shuttle and its crew at risk. In addition, the CV990 was able to land repeatedly to test the tires. The TAV was built from a kit and modified into a radio controlled, video-equipped machine to drill holes in aircraft test tires that were in imminent danger of exploding because of one or more conditions: high air pressure, high temperatures, and cord wear. An exploding test tire releases energy equivalent to two and one-half sticks of dynamite and can cause severe injuries to anyone within 50 ft. of the explosion, as well as ear injury - possibly permanent hearing loss - to anyone within 100 ft. The degree of danger is also determined by the temperature pressure and cord wear of a test tire. The TAV was developed by David Carrott, a PRC employee under contract to NASA.

jsc2019e040131 (7/17/2019) --- Tires are comprised of up to 60 different components, ranging from chemicals and fillers to multiple types of rubber and reinforcing cords. The Pushing the Limits of Silica Fillers for Tire Applications (Goodyear Tire) investigation evaluates creation of novel silica forms and structures, or morphologies, using traditional techniques to form silica fillers in microgravity. The space environment may yield results not possible in ground-based environments. Better understanding of silica morphology and the relationship between silica structure and properties may improve the silica design process as well as silica rubber formulation and tire manufacturing and performance on the ground.

A NASA CV-990, modified as a Landing Systems Research Aircraft (LSRA), lands on the Edwards AFB main runway in test of the space shuttle landing gear system. In this case, the shuttle tire failed, bursting into flame during the rollout. The space shuttle landing gear test unit, operated by a high-pressure hydraulic system, allowed engineers to assess and document the performance of space shuttle main and nose landing gear systems, tires and wheel assemblies, plus braking and nose wheel steering performance. The series of 155 test missions for the space shuttle program provided extensive data about the life and endurance of the shuttle tire systems and helped raise the shuttle crosswind landing limits at Kennedy. The CV-990 used as the LSRA was built in 1962 by the Convair Division of General Dynamics Corp., Ft. Worth, Texas, served as a research aircraft at Ames Research Center, Moffett Field, California, before it came to Dryden.

Tires from space shuttle Endeavour's final flight are on display at the California Science Center's, California Experience gallery, Tuesday, Oct. 30, 2012, in Los Angeles.

KENNEDY SPACE CENTER, FLA. -- This photo shows the leaking hydraulic seal in space shuttle Discovery's right main-gear strut. United Space Alliance and B.F. Goodrich technicians are working to replace the seal. The struts act as shock absorbers during the shuttle's landing. Engineers determined the observed leak of hydraulic fluid in the main landing gear strut exceeded specification and could not be reduced to an acceptable rate. Removing the strut and replacing seals require disconnecting and replacing the brakes and tires, disconnecting and reconnecting instruments and other requirements to allow access to the strut. Discovery had been scheduled to roll over Sept. 19 from its processing hangar to the Vehicle Assembly Building. A new rollover date will be set after technicians determine how long replacing the seal will take. Photo credit: NASA/George Shelton

One of two new payload transporters for Kennedy Space Center moves through Cape Canaveral Air Station after being unloaded from a barge at Port Canaveral. The transporters, manufactured by the KAMAG Transporttechnick, GmbH, of Ulm, Germany, are replacing the existing Payload Canister Transporter system, which is 20 years old. Each transporter is 65 feet long and 22 feet wide and has 24 tires divided between its two axles. The transporter travels 10 miles per hour unloaded, 5 miles per hour when loaded; it weighs up to 172,000 pounds when the canister with payloads rides atop. The transporters will be outfitted with four subsystems for monitoring the environment inside the canister during the payload moves: the Electrical Power System, Environmental Control System, Instrumentation and Communications System, and the Fluids and Gases System. Engineers and technicians are being trained on the transporter's operation and maintenance

This is a von Braun 1952 space station concept. In a 1952 series of articles written in Collier's, Dr. Wernher von Braun, then Technical Director of the Army Ordnance Guided Missiles Development Group at Redstone Arsenal, wrote of a large wheel-like space station in a 1,075-mile orbit. This station, made of flexible nylon, would be carried into space by a fully reusable three-stage launch vehicle. Once in space, the station's collapsible nylon body would be inflated much like an automobile tire. The 250-foot-wide wheel would rotate to provide artificial gravity, an important consideration at the time because little was known about the effects of prolonged zero-gravity on humans. Von Braun's wheel was slated for a number of important missions: a way station for space exploration, a meteorological observatory and a navigation aid. This concept was illustrated by artist Chesley Bonestell.

“Especially right now during the pandemic crisis, I love to occupy my mind. People say that they’re tired of being at home, but I don’t feel that. I practice yoga. I love decorating our house and working in the backyard during the summer time. If I don’t like where something is, I have to change it. That’s what I love. It’s the same thing with my work —I go outside the box to get ideas. I think about, how do I solve this? I apply the same skills to my creative passions and my current job. I create strategies for a better way of doing business for NASA. And I set the tone to keep me motivated and more productive.” NASA Senior Program Analyst, Jenny Acebron-Carlos, poses for a portrait at the Lincoln Memorial, Friday, Feb. 12, 2021 in Washington.

Discovery will carry the Integrated Truss Structure (ITS) Z1, Pressurized Mating Adapter 3 (PMA-3), Ku-band Communications System, and Control Moment Gyros (CMGs)

KENNEDY SPACE CENTER, FLA. -- In Orbiter Processing Facility bay 3, United Space Alliance and B.F. Goodrich technicians remove part of space shuttle Discovery's right main-gear strut where a leaking seal has been found. They will replace the seal. The struts act as shock absorbers during the shuttle's landing. Engineers determined the observed leak of hydraulic fluid in the main landing gear strut exceeded specification and could not be reduced to an acceptable rate. Removing the strut and replacing seals require disconnecting and replacing the brakes and tires, disconnecting and reconnecting instruments and other requirements to allow access to the strut. Discovery had been scheduled to roll over Sept. 19 from its processing hangar to the Vehicle Assembly Building. A new rollover date will be set after technicians determine how long replacing the seal will take. Photo credit: NASA/George Shelton

The first of two new payload transporters for Kennedy Space Center arrives at Port Canaveral. They were shipped by barge from their manufacturer, the KAMAG Company of Ulm, Germany. The transporters are used to carry spacecraft and International Space Station elements from payload facilities to and from the launch pads and orbiter hangars. Each transporter is 65 feet long and 22 feet wide and has 24 tires divided between its two axles. The transporter travels 10 miles per hour unloaded, 5 miles per hour when loaded; it weighs up to 172,000 pounds when the canister with payloads rides atop. The transporters will be outfitted with four subsystems for monitoring the environment inside the canister during the payload moves: the Electrical Power System, Environmental Control System, Instrumentation and Communications System, and the Fluids and Gases System. Engineers and technicians are being trained on the transporter's operation and maintenance. The new transporters are replacing the 20-year-old existing Payload Canister Transporter system
