![]() ![]() 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. The coronagraph instrument will demonstrate new technologies for performing direct imaging of exoplanets and disks around nearby stars.Within the next decade, NASA’s Nancy Grace Roman Space Telescope ( Roman Space Telescope) will be one million miles away from Earth, orbiting the L2 point (the second Lagrange Point), about four times further than the Moon, but in the direction away from the Sun. The mission will stare at the a dense star region toward the direction of the center of our Milky Way galaxy to observe microlensing events. The Roman Space Telescope will also study exoplanets with two different techniques: microlensing and through the use of a coronagraph technology demonstration. It will provide a huge step forward in our understanding of dark matter and dark energy. It will also observe distant Type Ia supernovae to use them as tracers of the accelerating expansion of the universe, providing an independent means of characterizing dark energy. All told, more than a billion galaxies will be observed. It will perform large surveys of galaxies and galaxy clusters to see the effects of dark matter and energy on their shapes and distributions in the universe. The Roman Space Telescope will study dark matter and dark energy with several techniques. How will it look for dark matter, dark energy and exoplanets?
