NASA letter of appreciation to a senior National Nuclear Security Administration technical expert for support to this report. In the 2005 Budget Authorization Act the U.S. Congress directed the NASA Administrator to provide an analysis of alternatives to detect track catalogue and characterize potentially hazardous near-Earth objects NEO. Congress required that the Administrator submit a program by December 28 2006 to survey 90% of the potentially hazardous objects measuring at least 140 meters in diameter by the end of 2020. In addition the legislation required the Administrator to submit an analysis of alternatives that NASA could employ to divert an object on a likely collision course with Earth. A study team led by the Office of Program Analysis and Evaluation PA&E derived requirements and figures of merit from the Act and used these factors to evaluate the alternatives. The team developed a range of options from public and private sources and then analyzed their capabilities levels of performance life-cycle costs schedules and development and operations risks. This document presents the detailed results of these analyses. A summary report was submitted to Congress in December of 2006. During related Congressional testimony on this report it was stated that The report's basic conclusion is that ``NASA recommends that the program continue as currently planned and we will also take advantage of opportunities using potential dual-use telescopes and spacecraft--and partner with other agencies as feasible--to attempt to achieve the legislated goal within 15 years. However due to current budget constraints NASA cannot initiate a new program at this time.'' In addition the report contained a number of additional findings <br /> including: ``The goal of the Survey Program should be modified to detect track catalogue and characterize by the end of 2020 90 percent of all Potentially Hazardous Objects PHOs greater than 140m whose orbits pass within 0.05 AU of the Earth's orbit as opposed to surveying for all NEOs; The Agency could achieve the specified goal of surveying for 90 percent of the potentially hazardous NEOs by the end of 2020 by partnering with other government agencies on potential future optical ground-based observatories and building a dedicated NEO survey asset assuming the partners' potential ground assets come online by 2010 and 2014 and a dedicated asset by 2015; Together the two observatories potentially to be developed by other government agencies could complete 83 percent of the survey by 2020 if observing time at these observatories is shared with NASA's NEO Survey Program; New space-based infrared systems combined with ground-based assets could reduce the overall time to reach the 90 percent goal by at least three years. Space systems have additional benefits as well as costs and risks compared to ground-based alternatives; Radar systems cannot contribute to the search for potentially hazardous objects but may be used to rapidly refine tracking and to determine object sizes for a few NEOs of potentially high interest. Existing radar systems are currently oversubscribed by other missions. Determining a NEO's mass and orbit is required to determine whether it represents a potential threat and to provide required information for most alternatives to mitigate such a threat. Beyond these parameters characterization requirements and capabilities are tied directly to the mitigation strategy selected.''. National Aeronautics and Space Administration paperback
200986131Washington DC: National Aeronautics and Space Administration 2009. Presumed First Edition First printing. Comb binding. Very good. 31 3 pages including covers. Contents include Media Services Information; Quick Facts; NASA's Search for Habitable Planets; Scientific Goals and Objectives; Mission Overview; Spacecraft; Instrument - Photometer; Selecting the Kepler Star Field; Education and Public Outreach; Other Exoplanet Activities; Science Team; and Project Management. 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.<br /> Designed to survey a portion of Earth's region of the Milky Way to discover Earth-size exoplanets in or near habitable zones and estimate how many of the billions of stars in the Milky Way have such planets Kepler's sole scientific instrument is a photometer that continually monitored the brightness of approximately 150000 main sequence stars in a fixed field of view. These data were transmitted to Earth then analyzed to detect periodic dimming caused by exoplanets that cross in front of their host star. Only planets whose orbits are seen edge-on from Earth could be detected. Kepler observed 530506 stars and detected 2778 confirmed planets as of June 16 2023. By January 2015 Kepler and its follow-up observations had found 1013 confirmed exoplanets in about 440 star systems along with a further 3199 unconfirmed planet candidates. Four planets have been confirmed through Kepler's K2 mission. In November 2013 astronomers estimated based on Kepler space mission data that there could be as many as 40 billion rocky Earth-size exoplanets orbiting in the habitable zones of Sun-like stars and red dwarfs within the Milky Way. It is estimated that 11 billion of these planets may be orbiting Sun-like stars. The nearest such planet may be 3.7 parsecs 12 ly away according to the scientists. On January 6 2015 NASA announced the 1000th confirmed exoplanet discovered by the Kepler space telescope. Four of the newly confirmed exoplanets were found to orbit within habitable zones of their related stars: three of the four Kepler-438b Kepler-442b and Kepler-452b are almost Earth-size and likely rocky; the fourth Kepler-440b is a super-Earth. On May 10 2016 NASA verified 1284 new exoplanets found by Kepler the single largest finding of planets to date. Kepler data has also helped scientists observe and understand supernovae; measurements were collected every half-hour so the light curves were especially useful for studying these types of astronomical events.

Very good. 63 1 pages. Illustrations. Mars Science Laboratory MSL is a robotic space probe mission to Mars launched by NASA on November 26 2011 which successfully landed Curiosity a Mars rover in Gale Crater on August 6 2012. The overall objectives include investigating Mars' habitability studying its climate and geology and collecting data for a human mission to Mars. The rover carries a variety of scientific instruments designed by an international team. Contents include Media Services Information; Quick Facts; Mars at a Glance: Mars Science Laboratory Investigations; Mission Overview; Comparing Two Mars Rover Projects; Spacecraft; Mars Science Laboratory Landing Site; Recent Current and Upcoming Missions; Mars Science: A Story of Changes; Historical Mars Missions; and Program/Project Management. For several reasons a different landing system was chosen for MSL compared to previous Mars landers and rovers. Curiosity was considered too heavy to use the airbag landing system as used on the Mars Pathfinder and Mars Exploration Rovers. The MSL engineers came up with a novel alternative solution: the sky crane. The sky crane system lowered the rover with a 25 ft tether to a soft landing—wheels down—on the surface of Mars. This system consists of a bridle lowering the rover on three nylon tethers and an electrical cable carrying information and power between the descent stage and rover. As the support and data cables unreeled the rover's six motorized wheels snapped into position. At roughly 25 ft below the descent stage the sky crane system slowed to a halt and the rover touched down. After the rover touched down it waited two seconds to confirm that it was on solid ground by detecting the weight on the wheels and fired several pyros small explosive devices activating cable cutters on the bridle and umbilical cords to free itself from the descent stage. The descent stage then flew away to a crash landing 2100 ft away. The sky crane concept had never been used in missions before. National Aeronautics and Space Administration unknown

The Viking program consisted of a pair of American space probes sent to Mars Viking 1 and Viking 2. Each spacecraft was composed of two main parts: an orbiter designed to photograph the surface and a lander designed to study the planet from the surface. The orbiters also served as communication relays for the landers. The Viking program grew from NASA's earlier Voyager Mars program. Viking 1 entered Mars orbit on June 19 1976 with Viking 2 following suit on August 7. After orbiting Mars for more than a month and returning images used for landing site selection the orbiters and landers detached; the landers then soft-landed. The Viking 1 lander touched down on the surface of Mars on July 20 1976 and was joined by the Viking 2 lander on September 3. The orbiters continued imaging and performing other scientific operations from orbit while the landers deployed instruments on the surface. Pictures from the Viking 1 and Viking 2 Landers as well as an account of the decade leading up to the Mars pictures by Tim Mutch leader of the Viking Lander Imaging Team. The Viking landers were the first completely successful spacecrafts to land on Mars. Before Viking arrived at Mars landing sites were chosen for both Viking landers. On July 20 1976 Viking lander 1 arrived at its chosen site in the western part of Chryse Planitia. On August 7 1976 Viking lander 2 touched down on Utopia Planitia. Each of the Viking landers carried a series of science packages which included a weather station a seismometer a chemical analysis package two cameras a soil composition package and a biological experiment package. Within minutes of lander 1's touch down the first picture was taken in case something happened to the spacecraft. This picture showed what looked like a sandy dusty surface with rocks up to 10 cm in diameter. The two cameras on each lander were mounted on opposite sides of the space craft. This allowed stereoscopic images to be taken which could be used to calculate distances from the lander to the features in the pictures.
