Momentive X Moon Landing

The moon landing, one of the most iconic moments in history, was imprinted by moon boots featuring GEs very own silicone sole. GE Silicones, who are now known as Momentive, developed thermally insulating and temperature resistant silicones worn by astronauts on July 20, 1969. Not only this, but they also created the gloves worn by Neil Armstrong and Buzz Aldrin on the Apollo 11 mission.

For more than 50 years, Momentive has continued to produce numerous silicone products used in NASA spacecrafts. They are frequently developing and refining their advanced silicone material for all aerospace and aviation applications from assembling, sealing and protecting critical components, they cover it all.

Momentive is also dedicated to inspiring future generations of engineers. A prototype of the moon boot used on Apollo 11 was donated to The Children’s Museum of Science and Technology in New York in hopes to be a useful resource for the adults of tomorrow.


A man named Richard Ellis is the person who captured the perfect blend of form and function. More than anyone, he decided what all the footprints on the moon would look like.

Mr. Ellis worked as a model maker for ILC Industries, now ILC Dover, the Delaware company that won the bid to create spacesuits for NASA’s Apollo program. ILC, best known for its Playtex division, also had military contracts for things like inflatable rafts.

Part of Mr. Ellis’s job was to take the 80 measurements of the astronauts so that engineers could design their suits. His lasting contribution, however, came from the blue silicone soles of the lunar overshoes.

Aldrin and Armstrong left their original pairs of trailblazing lunar overshoes at their landing site, Tranquility Base, due to the weight constraints for their moon rock-loaded return to Earth. In 2009, photographs captured by NASA's Lunar Reconnaissance Orbiter revealed that the boot prints left by the two astronauts remain visible today, more than four decades later.
