Lunar Infrastructure For Exploration
The Lunar Infrastructure for Exploration (LIFE) was a proposed project to build a space telescope on the far side of the Moon, actively promoted by EADS Astrium Space Transportation of Germany and the Netherlands Foundation for Research in Astronomy ASTRON/LOFAR. The project was presented for the first time publicly at the 2005 IAF Congress in Fukuoka. The 1.3 billion euro project would have involved a radio telescope to be located on the polar region of the far side of the Moon. The radio telescope was intended to look for exoplanets and detect signals in the 1-10 MHz range. Such signals cannot be detected on Earth because of ionosphere interference. The proposed telescope would have been constructed by a lander vehicle to deploy dipoles across a 300-400 m area. The dipoles, which receive the cosmic radio signals, would be deployed either by a dispenser or by a team of small mobile robots. The telescope would have been located near the South Pole to ensure permanent sunligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Observatory
A space telescope (also known as space observatory) is a telescope in outer space used to observe astronomical objects. Suggested by Lyman Spitzer in 1946, the first operational telescopes were the American Orbiting Astronomical Observatory, OAO-2 launched in 1968, and the Soviet Orion (space telescope), Orion 1 ultraviolet telescope aboard space station Salyut 1 in 1971. Space telescopes avoid several problems caused by the atmosphere, including the absorption or scattering of certain wavelengths of light, obstruction by clouds, and distortions due to atmospheric refraction such as twinkling. Space telescopes can also observe dim objects during the daytime, and they avoid light pollution which Observatory#Ground-based observatories, ground-based observatories encounter. They are divided into two types: Satellites which map the entire sky (astronomical survey), and satellites which focus on selected astronomical objects or parts of the sky and beyond. Space telescopes are distinct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dipole Antenna
In radio and telecommunications a dipole antenna or doublet is one of the two simplest and most widely used antenna types, types of antenna; the other is the monopole antenna, monopole. The dipole is any one of a class of antennas producing a radiation pattern approximating that of an elementary electric dipole with a radiating structure supporting a line current so energized that the current has only one node at each far end. A dipole antenna commonly consists of two identical conductive elements such as metal wires or rods. The driving current from the transmitter is applied, or for receiving antennas the output signal to the radio receiver, receiver is taken, between the two halves of the antenna. Each side of the feedline to the transmitter or receiver is connected to one of the conductors. This contrasts with a monopole antenna, which consists of a single rod or conductor with one side of the feedline connected to it, and the other side connected to some type of g ...

Lunar Crater Radio Telescope
__NOTOC__ The Lunar Crater Radio Telescope (LCRT) is a proposal by the NASA Institute for Advanced Concepts (NIAC) to create an ultra-long-wavelength (that is, wavelengths greater than 10 m, corresponding to frequencies below 30 MHz) radio telescope inside a lunar crater on the far side of the Moon. The reason for building the LCRT on the far side of the Moon would be to avoid interference faced by radio telescopes on the Earth's surface. The Moon would block many sources of radio interference originating on Earth, and would avoid the problems that come from Earth's ionosphere at long radio wavelengths. If completed, the telescope would have a structural diameter of 1.3 km, and the reflector would be 350m in diameter. Robotic lift wires and an anchoring system would enable origami deployment of the parabolic reflector. History A previous proposal put the reflector size at 1 km diameter. In 2021, the LCRT project went into phase II of development in the NIAC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Space Telescopes
This list of space telescopes (astronomy, astronomical space observatory, space observatories) is grouped by major frequency ranges: gamma ray, x-ray, ultraviolet, visible light, visible, infrared, microwave and radio. Telescopes that work in multiple frequency bands are included in all of the appropriate sections. Space telescopes that collect particles, such as cosmic ray nuclei and/or electrons, as well as instruments that aim to detect gravitational waves, are also listed. Missions with specific targets within the Solar System (e.g., the Sun and its planets), are excluded; see List of Solar System probes for these, and List of Earth observation satellites for missions targeting Earth. Two values are provided for the dimensions of the initial orbit. For telescopes in Geocentric orbit, Earth orbit, the minimum and maximum altitude are given in kilometers. For telescopes in solar orbit, the minimum distance (periapsis) and the maximum distance (apoapsis) between the telescope and ...

Berlin Air Show
The ILA Berlin Air Show (German: (ILA)) combines a major trade exhibition for the aerospace and defence industries with a public airshow. It is held every even year at the new Berlin ExpoCenter Airport next to the Berlin Brandenburg Airport in Schönefeld, Brandenburg 18 km southeast of Berlin, Germany. The most recent ILA Berlin Air Show was held in June 2024. Established in 1909, it claims to be world's oldest air show, and it is among the largest and most important aerospace trade fairs today. According to the organisers Messe Berlin GmbH, in 2012 the Berlin Air Show attracted 125,000 professional visitors and 105,000 members of the general public, with 3,600 journalists from 65 countries also attending. The format is similar to the Paris Air Show in France and the Farnborough International Airshow in Britain, the other major events in the European air show calendar.

Meteorite
A meteorite is a rock (geology), rock that originated in outer space and has fallen to the surface of a planet or Natural satellite, moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. It then becomes a meteor and forms a Meteoroid#Fireball, fireball, also known as a shooting star; astronomers call the brightest examples "Bolide#Astronomy, bolides". Once it settles on the larger body's surface, the meteor becomes a meteorite. Meteorites vary greatly in size. For geologists, a bolide is a meteorite large enough to create an impact crater. Meteorites that are recovered after being observed as they transit the atmosphere and impact event, impact Earth are called meteorite falls. All others are known as meteorite finds. Meteorites have traditionally been divided into three broad categories: stony meteorites that are rocks, mainly composed of sil ...

Geophone
A geophone is a device that converts ground movement (velocity) into voltage, which may be recorded at a recording station. The Standard deviation, deviation of this measured voltage from the base line is called the seismic response and is analyzed for structure of the Earth. Etymology The term geophone derives from the Greek word "γῆ (ge) " meaning "classical element, earth" and "phone" meaning "sound". Construction Geophones have historically been passive analog circuit, analog devices and typically comprise a spring-mounted wire coil moving within the field of a case-mounted permanent magnet to generate an electrical signal. Recent designs have been based on microelectromechanical systems (MEMS) technology which generates an electrical response to ground motion through an active feedback circuit to maintain the position of a small piece of silicon. The response of a coil/magnet geophone is proportional to ground velocity, while MEMS devices usually respond proportional t ...

Peak Of Eternal Light
A peak of eternal light (PEL) is a hypothetical point on the surface of an astronomical body that is always in sunlight. Such a peak must have high latitude, high elevation, and be on a body with very small axial tilt. The existence of such peaks was first postulated by Beer and Mädler in 1837. The pair said about the lunar polar mountains: "...many of these peaks have (with the exception of eclipses caused by the Earth) eternal sunshine". These polar peaks were later mentioned by Camille Flammarion in 1879, who speculated that there may exist at the poles of the Moon. PELs would be advantageous for space exploration and space colonization, colonization due to the ability of an electrical device located there to receive solar power regardless of the time of day or day of the year, and the relatively stable temperature range. Detailed lunar topography collected by the Lunar Reconnaissance Orbiter (LRO) suggests that no points on the Moon receive perpetual light during both the wint ...

Robot
A robot is a machine—especially one Computer program, programmable by a computer—capable of carrying out a complex series of actions Automation, automatically. A robot can be guided by an external control device, or the robot control, control may be embedded within. Robots may be constructed to evoke Humanoid robot, human form, but most robots are task-performing machines, designed with an emphasis on stark functionality, rather than expressive aesthetics. Robots can be autonomous robot, autonomous or semi-autonomous and range from humanoids such as Honda's ''Advanced Step in Innovative Mobility'' (ASIMO) and TOSY's ''TOSY Ping Pong Playing Robot'' (TOPIO) to industrial robots, robot-assisted surgery, medical operating robots, patient assist robots, dog therapy robots, collectively programmed Swarm robotics, ''swarm'' robots, UAV drones such as General Atomics MQ-1 Predator, and even microscopic Nanorobotics, nanorobots.
