Roger J. Thomas was a solar physicist who worked at NASA for many years. He was an internationally recognized expert on the design of extreme ultraviolet spectrographs, and received the prestigious NASA Exceptional Service Medal in 2009. [1]
Cassini–Huygens, commonly called Cassini, was a space-research mission by NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI) to send a space probe to study the planet Saturn and its system, including its rings and natural satellites. The Flagship-class robotic spacecraft comprised both NASA's Cassini space probe and ESA's Huygens lander, which landed on Saturn's largest moon, Titan. Cassini was the fourth space probe to visit Saturn and the first to enter its orbit, where it stayed from 2004 to 2017. The two craft took their names from the astronomers Giovanni Cassini and Christiaan Huygens.
The Rogers Commission Report was written by a Presidential Commission charged with investigating the Space Shuttle Challenger disaster during its 10th mission, STS-51-L. The report, released and submitted to President Ronald Reagan on June 9, 1986, both determined the cause of the disaster that took place 73 seconds after liftoff, and urged NASA to improve and install new safety features on the shuttles and in its organizational handling of future missions.
The Columbia Accident Investigation Board (CAIB) was an internal commission convened by NASA to investigate the destruction of the Space Shuttle Columbia during STS-107 upon atmospheric re-entry on February 1, 2003. The panel determined that the accident was caused by foam insulation breaking off from the external fuel tank, forming debris which damaged the orbiter's wing, and that the problem of "debris shedding" was well known but considered "acceptable" by management. The panel also recommended changes that should be made to increase the safety of future shuttle flights. The CAIB released its final report on August 26, 2003.
Dawn is a retired space probe that was launched by NASA in September 2007 with the mission of studying two of the three known protoplanets of the asteroid belt: Vesta and Ceres. In the fulfillment of that mission—the ninth in NASA's Discovery Program—Dawn entered orbit around Vesta on July 16, 2011, and completed a 14-month survey mission before leaving for Ceres in late 2012. It entered orbit around Ceres on March 6, 2015. In 2017, NASA announced that the planned nine-year mission would be extended until the probe's hydrazine fuel supply was depleted. On November 1, 2018, NASA announced that Dawn had depleted its hydrazine, and the mission was ended. The derelict probe remains in a stable orbit around Ceres.
George Michael Low was an administrator at NASA and the 14th president of the Rensselaer Polytechnic Institute. Low was one of the senior NASA officials who made decisions as manager of the Apollo Spacecraft Program Office in the Apollo program of crewed missions to the Moon.
The Kepler space telescope is a disused space telescope launched by NASA in 2009 to discover Earth-sized planets orbiting other stars. Named after astronomer Johannes Kepler, the spacecraft was launched into an Earth-trailing heliocentric orbit. The principal investigator was William J. Borucki. After nine and a half years of operation, the telescope's reaction control system fuel was depleted, and NASA announced its retirement on October 30, 2018.
The NASA Distinguished Service Medal is the highest award that can be bestowed by the National Aeronautics and Space Administration of the United States. The medal may be presented to any member of the federal government, including both military astronauts and civilian employees.
The Lunar and Planetary Institute (LPI) is a scientific research institute dedicated to study of the solar system, its formation, evolution, and current state. The Institute is part of the Universities Space Research Association (USRA) and is supported by the Science Mission Directorate of the National Aeronautics and Space Administration (NASA). Located at 3600 Bay Area Boulevard in Houston, Texas, the LPI maintains an extensive collection of lunar and planetary data, carries out education and public outreach programs, and offers meeting coordination and publishing services. The LPI sponsors and organizes several workshops and conferences throughout the year, including the Lunar and Planetary Science Conference (LPSC) held in March in the Houston area.
NGC 2903 is an isolated barred spiral galaxy in the equatorial constellation of Leo, positioned about 1.5° due south of Lambda Leonis. It was discovered by German-born astronomer William Herschel, who cataloged it on November 16, 1784. He mistook it as a double nebula, as did subsequent observers, and it wasn't until the nineteenth century that the Third Earl of Rosse resolved into a spiral form. J. L. E. Dreyer assigned it the identifiers 2903 and 2905 in his New General Catalogue; NGC 2905 now designates a luminous knot in the northeastern spiral arm.
NASA Extreme Environment Mission Operations, or NEEMO, is a NASA analog mission that sends groups of astronauts, engineers and scientists to live in the Aquarius underwater laboratory, the world's only undersea research station, for up to three weeks at a time in preparation for future space exploration.
The NASA Distinguished Public Service Medal is an award similar to the NASA Distinguished Service Medal, but awarded to non-government personnel. This is the highest honor NASA awards to anyone who was not a government employee when the service was performed.
The NASA Exceptional Engineering Achievement Medal was established by NASA in 1981 to recognize unusually significant engineering contributions towards achievement of aeronautical or space exploration goals. This award is given for individual efforts for applications of engineering principles or methods that have resulted in a contribution of fundamental importance in this field or have significantly enhanced understanding of this field or have significantly advanced the state of the practice as demonstrated by an application to aerospace systems.
The NASA Exceptional Scientific Achievement Medal was established by NASA on September 15, 1961, when the original ESM was divided into three separate awards. Under the current guidelines, the ESAM is awarded for unusually significant scientific contribution toward achievement of aeronautical or space exploration goals. This award may be given for individual efforts that have resulted in a contribution of fundamental importance in this field, or have significantly enhanced understanding of this field.
NGC 935 and IC 1801 are a pair of interacting galaxies within the Aries constellation. NGC 935 is the northern member of the pair and IC 1801 is the southern.
Roger Everett Summons is the Schlumberger Professor of Geobiology at the Massachusetts Institute of Technology and Professor of Geobiology in the Department of Earth, Atmospheric and Planetary Sciences.
Kepler-23 is a star in the northern constellation of Cygnus, the swan, that is orbited by a planet found to be unequivocally within the star's habitable zone. With an apparent visual magnitude of 14.0, this star is too faint to be seen with the naked eye.
Kepler-440b is a confirmed super-Earth exoplanet orbiting within the habitable zone of Kepler-440, about 850 light-years (261 pc) from Earth. The planet was discovered by NASA's Kepler spacecraft using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. NASA announced the confirmation of the exoplanet on 6 January 2015.
NGC 116 is a possibly lost or "non-existent" object in the constellation Cetus. This object is up for debate and has been considered to possibly be PGC 1671. The NED entry for this object contains the note NGC identification is very uncertain.
Obazoa is a proposed sister clade of Amoebozoa. The term Obazoa is based on the OBA acronym for Opisthokonta, Breviatea, and Apusomonadida, the group's three constituent clades.
