![]() ![]() SRTM collected topographic data over nearly 80% of Earth's land surfaces, creating the first-ever near-global dataset of land elevations. ![]() The Shuttle Radar Topography Mission (SRTM) payload flew aboard the Space Shuttle Endeavour during the STS-99 mission. ![]() Credit: NASA/JPL-Caltech/National Geospatial Intelligence Agency. Map color-coding is directly related to topographic height, with brown and yellow indicating lower elevations and green and white indicating higher elevations. In short, when Earth has questions, Hubble answers.Color shaded-relief image of Africa created from SRTM data. Since its fifth and final repair mission in 2009, the telescope has made over 1.4 million observations, located distant swirling galaxies and plotted pockets of dark matter.Īnalysis of Hubble’s images even helped earned scientists the Nobel Prize in 2011 for discovering that the rate that our universe is rapidly accelerating. Including that trip, there were five astronaut servicing missions to Hubble. Astronauts repaired Hubble in December 1993. Shortly after Hubble Space Telescope was deployed in 1990, the observatory's primary mirror was discovered to have an aberration that affected the clarity of the telescope's early images.įortunately, Hubble was the first telescope designed to be visited in space by astronauts to perform repairs, replace parts, and update its technology with new instruments. Hubble has operated far beyond its planned lifetime, but it has needed some repair work. Hubble gave us one of the most memorable and important images in human history: the Hubble Deep Field image which shows thousands of galaxies in just a tiny speck of sky. It also, of course, continues to dazzle us with stunning pictures of stars, galaxies and planets. Scientists have used Hubble to observe the most distant stars and galaxies as well as the planets in our solar system.ĭata and from the orbiting telescope are the backbone of more than 15,000 technical papers. The telescope has had a major impact on every area of astronomy, from the solar system to objects at the edge of the universe. Its domain extends from the ultraviolet, through the visible, and to the near-infrared. Hubble can see far more than what we can with our eyes. Far above the distortion of Earth's atmosphere, clouds and light pollution, Hubble has an unobstructed view of the universe. The first major optical telescope to be placed in space, Hubble operates from the ultimate mountaintop. The Hubble Space Telescope's launch and deployment in April 1990 marked the most significant advancement in astronomy since Galileo's telescope.
