description Overview

OAO-2

OAO-2 (Orbiting Astronomical Observatory 2), launched in December 1968, was NASA's first successful space-based ultraviolet observatory. The spacecraft carried multiple telescopes to observe the universe in ultraviolet wavelengths blocked by Earth's atmosphere. It provided critical early UV observations of stars, nebulae, and galaxies, proving the viability of extraterrestrial astronomy. The missi...

IRIS (Interface Region Imaging Spectrograph)

IRIS is a NASA small explorer spacecraft launched on June 27, 2013, from Vandenberg Air Force Base aboard a Pegasus XL rocket, designed to observe the Sun's chromosphere and transition region at ultraviolet wavelengths. Built by Lockheed Martin Solar and Astrophysics Laboratory and operating in Sun-synchronous orbit, its imaging spectrograph observes how solar material moves and gathers energy as...
