EGSEGS may refer to:
GEANT-3GEANT is the name of a series of simulation software designed to describe the passage of elementary particles through matter, using Monte Carlo methods. The name is an acronym formed from "GEometry ANd Tracking". Originally developed at CERN for high energy physics experiments, GEANT-3 has been used in many other fields.
EGS (program)The EGS (Electron Gamma Shower) computer code system is a general purpose package for the Monte Carlo simulation of the coupled transport of electrons and photons in an arbitrary geometry for particles with energies from a few keV up to several hundreds of GeV. It originated at SLAC but National Research Council of Canada and KEK have been involved in its development since the early 80s. Development of the original EGS code ended with version EGS4. Since then two groups have re-written the code with new physics: EGSnrc, maintained by the Ionizing Radiation Standards Group, Measurement Science and Standards, National Research Council of Canada EGS5, maintained by KEK, the Japanese particle physics research facility.
Sandy Stone (artist)Allucquére Rosanne "Sandy" Stone (born c. 1936) is an American academic theorist, media theorist, author, and performance artist. She is an Associate Professor Emerita at the University of Texas at Austin where she was the Founding Director of the Advanced Communication Technologies Laboratory (ACTLab) and the New Media Initiative in the department of Radio-TV-Film. Stone has worked in and written about film, music, experimental neurology, writing, engineering, and computer programming. Stone is transgender and is considered a founder of the academic discipline of transgender studies. Stone was inducted into the National Women's Hall of Fame on March 5, 2024 in a ceremony in New York City. In Stone's acceptance speech she spoke of "Trans vision: To learn to see, and then to be a light by which others can see."
Enhanced geothermal systemAn enhanced geothermal system (EGS) generates geothermal electricity without natural convective hydrothermal resources. Traditionally, geothermal power systems operated only where naturally occurring heat, water, and rock permeability are sufficient to allow energy extraction. However, most geothermal energy within reach of conventional techniques is in dry and impermeable rock. EGS technologies expand the availability of geothermal resources through stimulation methods, such as 'hydraulic stimulation'.
Exploration Ground SystemsNASA's Exploration Ground Systems (EGS) Program is one of three programs based at NASA's Kennedy Space Center in Florida. EGS was established to develop and operate the systems and facilities necessary to process and launch rockets and spacecraft during assembly, transport and launch. EGS is preparing the infrastructure to support NASA's Space Launch System (SLS) rocket and its payloads, such as the Orion spacecraft for Artemis I. Artemis I is the first to launch in a series of increasingly complex missions that will enable human exploration to the Moon and Mars.
Artemis programThe Artemis program is a Moon exploration program led by the United States' National Aeronautics and Space Administration (NASA), formally established in 2017 via Space Policy Directive 1. The program's stated long-term goal is to establish a permanent base on the Moon to facilitate human missions to Mars. It is intended to reestablish a human presence on the Moon for the first time since the Apollo 17 mission in 1972 and continue the direct exploration of Mars begun with data from the Mariner 9 probe in the same year. Two principal elements of the Artemis program are derived from the now-cancelled Constellation program: the Orion spacecraft (with the ESM instead of a US-built service module) and the Space Launch System's solid rocket boosters (originally developed for the Ares V). Other elements of the program, such as the Lunar Gateway space station and the Human Landing System, are in development by government space agencies and private spaceflight companies, collaborations bound by the Artemis Accords and governmental contracts. The Space Launch System, Orion spacecraft and the Human Landing System form the main spaceflight infrastructure for Artemis, and the Lunar Gateway plays a supporting role in human habitation. Supporting infrastructures for Artemis include the Commercial Lunar Payload Services, development of ground infrastructures, Artemis Base Camp on the Moon, Moon rovers, and spacesuits. Some aspects of the program have been criticized, such as the use of a near-rectilinear halo orbit and the program's sustainability. Orion's first launch on the Space Launch System was originally set in 2016, but faced numerous delays; it launched on November 16, 2022 as the Artemis I mission, with robots and mannequins aboard. As of May 2025, the crewed Artemis II launch is expected to take place in early 2026, the Artemis III crewed lunar landing is scheduled for mid-2027, the Artemis IV docking with the Lunar Gateway is planned for late 2028, the Artemis V docking with the European Space Agency's ESPRIT, Canada's Canadarm3, and NASA's Lunar Terrain Vehicle is planned for early 2030, and the Artemis VI docking which is expected to integrate the Crew and Science Airlock with the Lunar Gateway station is planned for early 2031. After Artemis VI, NASA plans yearly landings on the Moon from then on.
