Diagram of a MMRTG. The multi-mission radioisotope thermoelectric generator (MMRTG) is a type of radioisotope thermoelectric generator (RTG) developed for NASA space missions [1] 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.
SiGe has been used as a material in RTGs since 1976. Each mission that has used RTG technology involves exploration of far-reaching regions of the solar system. The most recent mission, New Horizons (2005), was originally set for a 3-year exploration, but was extended to 17 years.
Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
A spacecraft proposed to use this generator was the TiME boat-lander mission to Titan, the largest moon of the planet Saturn, with a launch intended for January 2015, [13] [14] or 2023. [15] In February 2009 it was announced that NASA/ESA had given Europa Jupiter System Mission (EJSM/Laplace) mission priority ahead of the Titan Saturn System ...
The multi-mission radioisotope thermoelectric generator of Mars Science Laboratory, sent to the surface of Mars to power that robotic rover Dragonfly is designed as a rotorcraft lander, much like a large quadcopter with double rotors, which is known as an octocopter. [ 3 ]
Rueda dancing requires a minimum of two couples, but could be as large as the maximum number of couples who can create a circle in the dance venue. (If necessary, multiple concentric circles can even be formed.) Since the 1990s, the music most commonly used for Rueda de Casino is either Salsa music or a unique variation of Salsa known as "Timba."
Some congresses cater more towards one style, such as Bachata, Cuban Salsa, LA/NY Salsa and NY on2, others give a taste of all styles and encourage salseros to experience different forms of dancing. As a general rule for beginners, improvers and intermediate dancers an 'all style' congress is the most suitable.
The oldest international salsa competition is the "Mayan World Salsa Championships", hosted by Club Mayan in LA. Publishing video-clips on this site did much to publicize salsa, especially LA-style salsa. For many years Johnny Vazquez dominated this competition before relocating to teach throughout Europe.
