![]() ![]() While the physics behind the HRG has been known for decades, it was the Northrop Grumman team who developed algorithms and mechanical manufacturing methods to perfect the process. He explained that if you rub your finger around a wine glass to make a sound, when you rotate the wine glass, you’ll hear a difference in the pitch. “The HRG is based on a theory of a wine glass,” said Larry Hershman, program manager for SSIRU. Inside the SSIRU, the gyros are a key element in stabilizing the telescope’s platform by detecting angular movement, which ensures the telescope can properly point to an exact location in the sky and detect light that will reveal previously unknown facts about the universe. The SSIRU has been used on a wide variety of military, commercial and science missions that require high-precision pointing. The HRG-based SSIRU has spent more than 50 million operating hours in orbit with 100% mission success. A star player is the Hemispherical Resonator Gyro (HRG), a sensor that has a proven track record of reliability and longevity, two features that will be critical for the Roman Space Telescope’s success. ![]() But inside the box, advanced electronics and sensors tell a bigger story. Pairing Wine Glass Physics with Advanced Algorithmsįrom the outside, the Scalable Space Inertial Reference Unit (SSIRU) looks deceptively simple - it appears to be a foot-long black box with a few basic controls. But if your shaky hand can make a once-in-a-lifetime photo blurry, just imagine the importance of a having a reliably steady telescope in space. To do these things, the images it takes must be stunningly sharp – the equivalent of being able to see which way a firefly is facing in a photo taken from a distance of 10 miles. Set to launch in the mid-2020s, the Roman Space Telescope will measure light from other galaxies and search for mysterious celestial objects such as rogue planets that wander through the universe without a star. Named for NASA’s first chief of astronomy who assisted with the Hubble Space Telescope launch, the Roman Space Telescope will help answer essential astrophysics questions about dark energy, dark matter, exoplanets and infrared astrophysics.
