Space Physics Research Laboratory

Welcome to the Space Physics Research Laboratory and XTRM Labs!

For over 75 years, our technicians have built electronics that operate in one of the most forbidding environments we know, with ionizing radiation from the Sun and a chill close to absolute zero. XTRM labs grew out of the Space Physics Research Laboratory (SPRL).

We’ve designed components for orbit and for landing on the moon, dust-storm-prone Mars and even a comet. But you don’t have to go to space to find these environments. Researchers operating in deserts have to put up with dust storms, those in tundra deal with frigid temperatures, and in the deep sea, pressures can reach a crushing eight tons per square inch. XTRM labs bring our space environment expertise back down to Earth. Find out how we can help you.
