NASA SPACE TELESCOPE IMAGING TECHNOLOGY

MISSION FACTS ENABLING TECHNOLOGY

> Wide Field and Planetary Camera HUBBLE SPACE TELESCOPE Better understand > Completed more than 1.3 MILLION OBSERVATIONS the age of the universe > Traveled 4+ BILLION MILES on low Earth orbit 4+ > Goddard High Resolution Spectrograph “THE FORERUNNER” BILLION > Discovered that the universe is approximately MILES > High Speed Photometer L3HARRIS ROLE: 13.7 BILLION YEARS OLD > Faint Object Camera & Spectrograph Provided ﬁne guidance and focus control systems and 2.4m backup mirror

CHANDRA X-RAY Explain the structure, > Uses X-RAY VISION to detect extremely hot, > High Resolution Camera activity and evolution high-energy regions of space OBSERVATORY > Advanced CCD Imaging Spectrometer of the universe > Flies 200 TIMES HIGHER than Hubble – X-RAY “THE DETECTIVE” VISION > High Energy Transmission more than 1/3 of the way to the moon Grating Spectrometer L3HARRIS ROLE: > Provides data on quasars as they were > Low Energy Transmission Designed, integrated and 10 BILLION YEARS AGO Grating Spectrometer tested imaging system

JAMES WEBB Observe distant events > Will be the MOST POWERFUL space telescope ever > Near-Infrared Camera and objects, such as the SPACE TELESCOPE > Will balance between gravity of Earth and sun > Near-Infrared Spectrograph formation of the ﬁrst 940,000 MILES IN SPACE MOST “THE HISTORIAN” galaxies, stars and POWERFUL > Mid-Infrared Instrument planets in the universe > 6.5-METER MIRROR made of 18 gold-coated > Fine Guidance Sensor/Near InfraRed L3HARRIS ROLE: beryllium segments Imager and Slitless Spectrograph Integrated optical telescope element and Integrated Science Instrument Module, designed and facilitated cryogenic testing

NANCY GRACE ROMAN Uncover information > Will provide images of ICE AND GAS EXOPLANETS > Wide Field Instrument on dark energy, dark around nearby stars > Coronagraph SPACE TELESCOPE matter, exoplanets and infrared NEW > Expected to observe more than 1 BILLION GALAXIES, > High Stability Thermal Control “THE CARTOGRAPHER” astrophysics – some of the 2,000 SUPERNOVAS AND 2,000 EXOPLANETS GALAXIES most enduring mysteries of > Should uncover MILLIONS OF NEW GALAXIES, L3HARRIS ROLE: the universe Repurpose the telescope to meet many early in development mission requirements, develop instrument enabling hardware, integrate and test to validate performance
