Geoffrey Alan Landis is an American aerospace engineer and author, working for the National Aeronautics and Space Administration (NASA) on planetary exploration, interstellar propulsion, solar power and photovoltaics. He holds nine patents, primarily in the field of improvements to solar cells and photovoltaic devices and has given presentations and commentary on the possibilities for interstellar travel and construction of bases on the Moon, Mars, and Venus.
Venera 3 was a Venera program space probe that was built and launched by the Soviet Union to explore the surface of Venus. It was launched on 16 November 1965 at 04:19 UTC from Baikonur, Kazakhstan, USSR. The probe comprised an entry probe, designed to enter the Venus atmosphere and parachute to the surface, and a carrier/flyby spacecraft, which carried the entry probe to Venus and also served as a communications relay for the entry probe.
NASA's Long Duration Exposure Facility, or LDEF, was a school bus-sized cylindrical facility designed to provide long-term experimental data on the outer space environment and its effects on space systems, materials, operations and selected spores' survival. It was placed in low Earth orbit by Space ShuttleChallenger in April 1984. The original plan called for the LDEF to be retrieved in March 1985, but after a series of delays it was eventually returned to Earth by Columbia in January 1990.
The apex is the highest point of something. The word may also refer to:
Solar electric propulsion (SEP) refers to the combination of solar cells and electric thrusters to propel a spacecraft through outer space. This technology has been exploited in a variety of spacecraft by the European Space Agency (ESA), the JAXA, Indian Space Research Organisation (ISRO) and NASA. SEP has a significantly higher specific impulse than normal chemical rockets, thus requiring less propellant mass to be launched with a spacecraft. The technology has been evaluated for missions to Mars.
Submillimetre astronomy or submillimeter astronomy is the branch of observational astronomy that is conducted at submillimetre wavelengths of the electromagnetic spectrum. Astronomers place the submillimetre waveband between the far-infrared and microwave wavebands, typically taken to be between a few hundred micrometres and a millimetre. It is still common in submillimetre astronomy to quote wavelengths in 'microns', the old name for micrometre.
A solar cell, or photovoltaic cell, is an electronic device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Individual solar cell devices are often the electrical building blocks of photovoltaic modules, known colloquially as solar panels. The common single junction silicon solar cell can produce a maximum open-circuit voltage of approximately 0.5 to 0.6 volts.
Spacecraft operating in the inner Solar System usually rely on the use of power electronics-managed photovoltaic solar panels to derive electricity from sunlight. Outside the orbit of Jupiter, solar radiation is too weak to produce sufficient power within current solar technology and spacecraft mass limitations, so radioisotope thermoelectric generators (RTGs) are instead used as a power source.
The Integrated Truss Structure (ITS) of the International Space Station (ISS) consists of a linear arranged sequence of connected trusses on which various unpressurized components are mounted such as logistics carriers, radiators, solar arrays, and other equipment. It supplies the ISS with a bus architecture. It is approximately 110 meters long and is made from aluminium and stainless steel.
The electrical system of the International Space Station is a critical resource for the International Space Station (ISS) because it allows the crew to live comfortably, to safely operate the station, and to perform scientific experiments. The ISS electrical system uses solar cells to directly convert sunlight to electricity. Large numbers of cells are assembled in arrays to produce high power levels. This method of harnessing solar power is called photovoltaics.
The Stykovochnyy Otsek, GRAU index 316GK, otherwise known as the Mir docking module or SO, was the sixth module of the Russian space station Mir, launched in November 1995 aboard the Space ShuttleAtlantis. The module, built by RKK Energia, was designed to help simplify space shuttle dockings to Mir during the Shuttle-Mir programme, preventing the need for the periodic relocation of the Kristall module necessary for dockings prior to the compartment's arrival. The module was also used to transport two new photovoltaic arrays to the station, as a mounting point for external experiments, and as a storage module when not in use for dockings.
Sharp Solar, a subsidiary of Sharp Electronics, is a solar energy products company owned by Sharp Corporation and based in Osaka, Japan.
The Micro-satellite Technology Experiment (MiTEx) is a microsatellite-based mission launched into geosynchronous orbit 21 June 2006 aboard a Delta II rocket. The USAF described the mission as a "technology demonstration" for the Defense Advanced Research Projects Agency (DARPA), the United States Air Force (USAF) and the United States Navy.
The multi-mission radioisotope thermoelectric generator (MMRTG) is a type of radioisotope thermoelectric generator (RTG) developed for NASA space missions such as the Mars Science Laboratory (MSL), under the jurisdiction of the United States Department of Energy's Office of Space and Defense Power Systems within the Office of Nuclear Energy. The MMRTG was developed by an industry team of Aerojet Rocketdyne and Teledyne Energy Systems.
The Space Coast Next Generation Solar Energy Center is a 10 megawatt (MW) solar photovoltaic (PV) facility at the Kennedy Space Center, Florida. Commissioned in April 2010, the center is the result of a partnership between NASA and Florida Power & Light. The facility has approximately 35,000 solar photovoltaic panels from SunPower covering an area of 60 acres. The facility provides slightly less than one percent of the power needed to keep Kennedy Space Center up and running.
Exploration Flight Test-1 or EFT-1 was the first test flight of the crew module portion of the Orion Multi-Purpose Crew Vehicle. Without a crew, it was launched on December 5, 2014, at 12:05 UTC, by a Delta IV Heavy rocket from Space Launch Complex 37B at Cape Canaveral Space Force Station.
