Lunar Reconnaissance Orbiter. The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric polar mapping orbit. [6][7] Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. [8] Its detailed mapping program is identifying safe ...
The Lunar Orbiter program was a series of five uncrewed lunar orbiter missions launched by the United States in 1966 and 1967. Intended to help select Apollo landing sites by mapping the Moon's surface, [1] they provided the first photographs from lunar orbit and photographed both the Moon and Earth. All five missions were successful, and 99 ...
Image as originally shown to the public displays extensive flaws and striping. Earth taken from Lunar Orbiter 1 in 1966. This image shows the improvement in picture quality after capture and reprocessing by LOIRP. The Lunar Orbiter Image Recovery Project (LOIRP) was a project to digitize the original analog data tapes from the five Lunar ...
A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft, and a variable-shaped pickup coil. When the coil nears metal, the control box signals its presence with a ...
LADEE. The Lunar Atmosphere and Dust Environment Explorer (LADEE; / ˈlædi /) [5] was a NASA lunar exploration and technology demonstration mission. It was launched on a Minotaur V rocket from the Mid-Atlantic Regional Spaceport on September 7, 2013. [6] During its seven-month mission, LADEE orbited the Moon's equator, using its instruments to ...
Lunar Orbiter 1. The 1966 Lunar Orbiter 1 robotic spacecraft mission, part of NASA 's Lunar Orbiter program, [9] was the first American spacecraft to orbit the Moon. It was designed primarily to photograph smooth areas of the lunar surface for selection and verification of safe landing sites for the Surveyor and Apollo missions.
Orbiter Processing Facility (OPF) is a class of hangars where U.S. Space Shuttle orbiters underwent maintenance between flights. They are located west of the Vehicle Assembly Building, where the orbiter was mated with its external tank and Solid Rocket Boosters before transport to the launch pad. OPF-1 and OPF-2 are connected with a low bay ...
The "asymmetric conduction" of electric current across electrical contacts between a crystal and a metal was discovered in 1874 by Karl Ferdinand Braun. [6] Crystals were first used as radio wave detectors in 1894 by Jagadish Chandra Bose in his microwave experiments. [7][8] Bose first patented a crystal detector in 1901. [9]
