Minimize Downtime for Manned Spaceflight
Minimize Downtime for Manned Spaceflight

In manned space missions, Gore’s space cables for LEO applications transmit data reliably to minimize downtime.

Low-orbit spaceflight requires cables to perform under considerable stress. Cables need to withstand abrasion and do so at extreme temperatures that could make them more brittle — or else risk the failure of critical data transmission, leading to costly downtime.

GORE Space Cables, Type SPM for low Earth orbit (LEO) applications help integration teams stay on schedule and avoid downtime. Qualified according to ESCC 3901/018, the cables are particularly well-suited for use in satellites, manned space missions and transport vehicles.

Because of the cables’ robust insulation, they can resist scrape abrasion and other stressors. They also feature outstanding thermal stability; as spaceflights venture into temperatures as high as +200°C — and as low as -200°C to — GORE Space Cables maintain their signal integrity. And because the cables are chemically inert, they withstand the atomic oxygen commonly found in low orbit environments.

The Science Behind the Cables

The key to the space cables’ outstanding performance is the proprietary material used in the cable insulation — expanded polytetrafluoroethylene (ePTFE). By incorporating ePTFE into the insulation, Gore uses a hybrid insulation that provides the best ATOX resistance available on the market today. This unique ePTFE material is chemically inert and thermal-resistant, which means that GORE Space Cables for low Earth orbit (LEO) applications withstand atomic oxygen commonly found in low orbit environments.
