WISE was launched in December 2009, and surveyed the full sky in four infrared wavelength bands (3.4, 4.6, 12 and 22 μm) until the frozen hydrogen cooling the telescope was depleted in September 2010.

But one year later and one year wiser, a team of Cornell University astronomers and researchers is preparing for the first spacecraft to orbit an asteroid, named 433 Eros, on Valentine's Day. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. Its mission: to study galaxies, stars, asteroids and comets by … The spacecraft flew in a 526x531 km x 97.5°, 6pm ascending node, sun-synchronous polar orbit. In deep space, there are very few second chances.

NASA gave the telescope a new name, Near-Earth Object WISE, shortened to NEOWISE. WISE was placed into a Sun-synchronous polar orbit on a Delta II 7320 launch vehicle on December 14, 2009. The purpose of Hubble is to study the cosmos from low-Earth orbit. Kessler, “Critical Density of Spacecraft in Low Earth Orbit” (NASA JSC-28949, NASA Johnson Space Center, Houston, TX, 2000). WISE also observed this asteroid 3 days before the discovery arc and also a few times later, so the total number of WISE observations is 18 spread over 106 hours. LightSail 2 features a small, bread-loaf-sized satellite and four large solar sails. In 2013 NASA woke up the telescope and gave it a new mission, to assist with the efforts to identify and characterize the population of near-Earth objects. WISE surveyed the full sky in four infrared wavelength bands (3.4, 4.6, 12 and 22 μm) until the frozen hydrogen cooling the telescope was depleted in September 2010. The launch of the Delta II rocket carrying the WISE spacecraft was originally scheduled for December 11, 2009. The launch was then rescheduled for December 14, 2009. The WISE telescope scanned continuously at near constant Ecliptic longitudes while a scan mirror temporarily froze the sky on the focal planes. Sets of exposures (7.7 sec in W1 and W2 and 8.8 sec in W3 and W4) were acquired at each point on the sky as the telescope scanned from pole-to-pole. It is the product of two decades of research and development by 10,000 scientists and engineers at various NASA centers, private companies, universities, and the European Space Agency. This attempt was scrubbed to correct a problem with a booster rocket steering engine. NASA.gov brings you the latest images, videos and news from America's space agency. An artist’s conception of the WISE satellite in orbit around Earth. Just before sunrise on Dec. 14, 2009, a Delta-II rocket lifted off from California's Vandenberg Air Force Base and brought NASA's Wide-field Infrared Survey Explorer (WISE) to low-Earth orbit. This list of space telescopes (astronomical space observatories) is grouped by major frequency ranges: gamma ray, x-ray, ultraviolet, visible, infrared, microwave and radio.Telescopes that work in multiple frequency bands are included in all of the appropriate sections. WISE is a NASA-funded Explorer mission that will provide a vast storehouse of knowledge about the solar system, the Milky Way, and the Universe. The rocket successfully placed the WISE spacecraft into the planned polar orbit at an altitude of 326 miles (525 km) above the Earth. 13. D. J. Kessler, P. D. Anz-Meador, “Critical number of space-craft in Low Earth Orbit: Using satellite fragmentation data to evaluate the stability of the orbital debris envi-ronment” (ESA SP-473, 265-272, ESOC, Darmstadt, Germany, 2001). It has a mass of 661 kg. What they call on-orbit hibernation. Chang'e 5-T1 experimental spacecraft DFH-3A "service module" was sent to the Earth-Moon L 2 lunar Lissajous orbit on 13 January 2015, where it used the remaining 800 kg of fuel to test maneuvers key to future lunar missions. WISE observed the object 9 times over a 33 hour time span, and this gave an orbit good enough to get a preliminary designation (2010 CK9), ground-based followup two months later, and to connect to the previous short observational arcs. The first of the Great Observatories was deployed from the Space Shuttle Discovery into Earth orbit in April 1990. It uses 301 W of power, while the solar panels can provide over 500 W. The 40 cm diameter telescope sits inside a solid-hydrogen cooled cryostat. Among the objects WISE will study are asteroids, the coolest and dimmest stars, and the most luminous galaxies. The WISE flight system is 285 cm tall, 200 cm wide and 173 cm deep. The survey continued as NEOWISE for an additional four months … The second attempt launched on time at 14:09:33 UTC (06:09 local PST) from Vandenberg Air Force Base in California. Space Sciences Lab (1tlendez 2008). NASA's WISE (Wide-field Infrared Survey Explorer) spacecraft was successfully launched to near-Earth orbit December 14, 2009, to serve as an infrared-wavelength astronomical space telescope.
