Spacewatch was founded in 1980 by Tom Gehrels and Robert S. McMillan, and is currently led by astronomer Melissa Brucker at the University of Arizona. Spacewatch uses several telescopes on Kitt Peak for follow-up observations of near-Earth objects. [3] The Spacewatch Project uses three telescopes of apertures 0.9-m, 1.8-m, and 2.3-m.
Such a mission would have allowed use of the 3.4 and 4.6 μm detectors after the last of cryo-coolant had been exhausted, with the goal of completing a second sky survey to detect additional objects and obtain parallax data on putative brown dwarf stars. NASA extended the mission in October 2010 to search for near-Earth objects (NEO). [12]
Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA's Explorer program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. [6]
During the mission, an uncrewed Orion capsule spent 10 days in a distant retrograde 60,000 kilometers (37,000 mi) orbit around the Moon before returning to Earth. [10] Artemis II, the first crewed mission of the program, will launch four astronauts in 2025 [11] on a free-return flyby of the Moon at a distance of 8,900 kilometers (5,500 mi). [12 ...
The ESA dropped out, and the mission did not proceed. [26] [27] NASA redefined mission requirements and decided to proceed with a 2020s mission to visit Didymos with an impactor, which had been considered as a part of the earlier AIDA mission, named the Double Asteroid Redirection Test or DART. The NASA mission was intended to test whether a ...
[4] [5] [6] The NEO Surveyor mission will be a successor to the NEOWISE mission, and the two missions have the same principal investigator, Amy Mainzer at the University of Arizona. [ 7 ] [ 8 ] Since first proposed in 2006, the concept repeatedly competed unsuccessfully for NASA funding against science missions unrelated to planetary defense ...
NASA officials have said they maintain close contact with SpaceX about its missions because of the agency's frequent work with the company. Spokespeople at NASA didn't respond to Reuters ...
Dinkinesh, the name borrowed from an Ethiopian word for the Lucy fossil, was the first flyby target of NASA's Lucy mission, which approached 425 km (264 mi) from the asteroid on 1 November 2023. [9] During the flyby, the Lucy spacecraft discovered that Dinkinesh has a contact-binary natural satellite , named Selam, which is 220 meters (720 ft ...
