Baltimore, MD. For every Social Security Account Number issued an "emploee master card" is made in the Social Security Board Records Office. Identifying data, given on the application blank , Form SC-5[?], is transferred to this master card in the form of up-ended quadrangular holes, punched by key punch machines, which have a key card like a typewriter. Each key struck by an operator causes a [...] to be punched into the card. The position of a hole determines the letter or number other machines will reproduce from the master card. From this master card is made an acturial card, to be used later in statistical purposes. The master card also is used in other machines which sort them numerically, according to account numbers alphabetically according to the name code, translate the holes into numbers and letters, and print the data on individual ledger sheets, indexes, registry of accounts, and other uses. It is kept as a permanent record. The photograph above shows at work a part of the key machine section, where master cards are punched.

KENNEDY SPACE CENTER, FLA. -- NASA's Galaxy Evolution Explorer spacecraft is successfully rotated to horizontal in preparation for mating with the Pegasus XL launch vehicle. The GALEX, set to launch April 2 from Cape Canaveral Air Force Station, will carry into space an orbiting telescope that will observe a million galaxies across 10 billion years of cosmic history to help astronomers determine when the stars and elements we see today had their origins. From its orbit high above Earth, the spacecraft will sweep the skies for 28 months using state-of-the-art ultraviolet detectors.  Looking in the ultraviolet will single out galaxies dominated by young, hot, short-lived stars that give off a great deal of energy at that wavelength.  These galaxies are actively creating stars, and therefore provide a window into the history and causes of star formation in galaxies. KSC-03pd0624

KENNEDY SPACE CENTER, FLA. - Orbital Sciences' L-1011 aircraft takes off from Cape Canaveral Air Force Station carrying the Pegasus XL rocket/Galaxy Evolution Explorer (GALEX) under its belly.  Release of the Pegasus was scheduled for about 8 a.m. over the Atlantic Ocean at an altitude of 39,000 feet at a location approximately 100 nautical miles offshore east-northeast of Cape Canaveral. Spacecraft separation from the Pegasus occurs 11 minutes later. At that time the satellite will be in a circular orbit of 431 statute miles (690 km) at a 29-degree inclination.

KENNEDY SPACE CENTER, FLA. --  At Astrotech Space Operations in Titusville, Fla., workers maneuver one of the THEMIS probes before installing bolt cutters that will separate each probe from the payload carrier. The probes will undergo weeks of testing and launch preparations. This includes a functional performance test to verify the state of health of each of the five probes and pressurization and leak checks of the reaction control systems.  THEMIS consists of five identical probes, the largest number of scientific satellites ever launched into orbit aboard a single rocket. This unique constellation of satellites will resolve the tantalizing mystery of what causes the spectacular sudden brightening of the aurora borealis and aurora australis - the fiery skies over the Earth's northern and southern polar regions. These lights are the visible manifestations of invisible energy releases, called geomagnetic substorms, in near-Earth space. THEMIS will not only seek to answer where and when substorms start, but will also provide clues as to how and why these space storms create havoc on satellites, terrestrial power grids, and communication systems.  THEMIS is scheduled to launch Feb. 15 from Cape Canaveral Air Force Station. Photo credit: NASA/Jack Pfaller KSC-06pd2803

CAPE CANAVERAL, Fla. – In the control room at the Astrotech Space Operations facility in Titusville, Fla., test conductors from ASTROTECH and Kennedy Space Center monitor data received from the clean room as technicians sample the monomethylhydrazine propellant that will be loaded aboard the Solar Dynamics Observatory, or SDO.    The hydrazine fuel is being sampled for purity before it is loaded aboard the spacecraft.  The technicians are dressed in self-contained atmospheric protective ensemble suits, or SCAPE suits, as a safety precaution in the unlikely event that any of the highly toxic chemical should escape from the storage tank. The nitrogen tetroxide oxidizer was loaded earlier in the week which is customarily followed by loading of the fuel.  Propellant loading is one of the final processing milestones before the spacecraft is encapsulated in its fairing for launch.  SDO is the first mission in NASA's Living With a Star Program and is designed to study the causes of solar variability and its impacts on Earth. The spacecraft's long-term measurements will give solar scientists in-depth information to help characterize the interior of the Sun, the Sun's magnetic field, the hot plasma of the solar corona, and the density of radiation that creates the ionosphere of the planets. The information will be used to create better forecasts of space weather needed to protect the aircraft, satellites and astronauts living and working in space. Liftoff aboard an Atlas V rocket is targeted for Feb. 9 from Launch Complex 41 on Cape Canaveral Air Force Station. For information on SDO, visit http://www.nasa.gov/sdo.

KENNEDY SPACE CENTER, FLA. --  At Astrotech Space Operations in Titusville, Fla., workers prepare one of the THEMIS probes for installation of bolt cutters that will separate each probe from the payload carrier.  The probes will undergo weeks of testing and launch preparations. This includes a functional performance test to verify the state of health of each of the five probes and pressurization and leak checks of the reaction control systems.  THEMIS consists of five identical probes, the largest number of scientific satellites ever launched into orbit aboard a single rocket. This unique constellation of satellites will resolve the tantalizing mystery of what causes the spectacular sudden brightening of the aurora borealis and aurora australis - the fiery skies over the Earth's northern and southern polar regions. These lights are the visible manifestations of invisible energy releases, called geomagnetic substorms, in near-Earth space. THEMIS will not only seek to answer where and when substorms start, but will also provide clues as to how and why these space storms create havoc on satellites, terrestrial power grids, and communication systems.

CAPE CANAVERAL, Fla. – At the Astrotech Space Operations facility in Titusville, Fla., Boeing spacecraft fueling technicians from Kennedy Space Center prepare to sample the monomethylhydrazine propellant that will be loaded aboard the Solar Dynamics Observatory, or SDO, which is protectively covered.    The hydrazine fuel is being sampled for purity before it is loaded aboard the spacecraft.  The technicians are dressed in self-contained atmospheric protective ensemble suits, or SCAPE suits, as a safety precaution in the unlikely event that any of the highly toxic chemical should escape from the storage tank. The nitrogen tetroxide oxidizer was loaded earlier in the week which is customarily followed by loading of the fuel.  Propellant loading is one of the final processing milestones before the spacecraft is encapsulated in its fairing for launch.  SDO is the first mission in NASA's Living With a Star Program and is designed to study the causes of solar variability and its impacts on Earth. The spacecraft's long-term measurements will give solar scientists in-depth information to help characterize the interior of the Sun, the Sun's magnetic field, the hot plasma of the solar corona, and the density of radiation that creates the ionosphere of the planets. The information will be used to create better forecasts of space weather needed to protect the aircraft, satellites and astronauts living and working in space. Liftoff aboard an Atlas V rocket is targeted for Feb. 9 from Launch Complex 41 on Cape Canaveral Air Force Station. For information on SDO, visit http://www.nasa.gov/sdo.

KENNEDY SPACE CENTER, FLA. - At Cape Canaveral Air Force Station, workers finish attaching the mated Pegasus XL and Galaxy Evolution Explorer (GALEX) satellite to the Orbital Sciences L-1011 aircraft.  The GALEX, to be launched April 28 from the L-1011, will carry into space an orbiting telescope that will observe a million galaxies across 10 billion years of cosmic history to help astronomers determine when the stars and elements we see today had their origins. The spacecraft will sweep the skies for 28 months using state-of-the-art ultraviolet detectors to single out galaxies dominated by young, hot, short-lived stars that give off a great deal of energy at that wavelength.  These galaxies are actively creating stars, and therefore provide a window into the history and causes of star formation in galaxies. KSC-03pd1246

KENNEDY SPACE CENTER, FLA. - At Cape Canaveral Air Force Station, Orbital Sciences' L-1011 aircraft waits for takeoff time between 7:50 and 9:50 a.m. EDT.  Attached underneath is the Pegasus XL rocket with its payload, the Galaxy Evolution Explorer (GALEX), due to be released about 8 a.m.  The GALEX will carry into space an orbiting telescope that will observe a million galaxies across 10 billion years of cosmic history to help astronomers determine when the stars and elements we see today had their origins. The spacecraft will sweep the skies for 28 months using state-of-the-art ultraviolet detectors to single out galaxies dominated by young, hot, short-lived stars that give off a great deal of energy at that wavelength.  These galaxies are actively creating stars, and therefore provide a window into the history and causes of star formation in galaxies. KSC-03pd1283

KENNEDY SPACE CENTER, FLA. --  At Astrotech Space Operations in Titusville, Fla., a worker installs bolt cutters on one of the THEMIS probes. The cutters will separate each probe from the payload carrier.  The probes will undergo weeks of testing and launch preparations. This includes a functional performance test to verify the state of health of each of the five probes and pressurization and leak checks of the reaction control systems.  THEMIS consists of five identical probes, the largest number of scientific satellites ever launched into orbit aboard a single rocket. This unique constellation of satellites will resolve the tantalizing mystery of what causes the spectacular sudden brightening of the aurora borealis and aurora australis - the fiery skies over the Earth's northern and southern polar regions. These lights are the visible manifestations of invisible energy releases, called geomagnetic substorms, in near-Earth space. THEMIS will not only seek to answer where and when substorms start, but will also provide clues as to how and why these space storms create havoc on satellites, terrestrial power grids, and communication systems.  THEMIS is scheduled to launch Feb. 15 from Cape Canaveral Air Force Station. Photo credit: NASA/Jack Pfaller KSC-06pd2801

KENNEDY SPACE CENTER, FLA. --   In the mobile service tower on Pad 17-B at Cape Canaveral Air Force Station, workers observe and help guide the second half of the fairing toward the THEMIS spacecraft.  The first half has already been put in place.  The fairing is a molded structure that fits flush with the outside surface of the Delta II upper stage booster and forms an aerodynamically smooth nose cone, protecting the spacecraft during launch and ascent. THEMIS is an acronym for Time History of Events and Macroscale Interactions during Substorms.  THEMIS consists of five identical probes that will track violent, colorful eruptions near the North Pole.  This will be the largest number of scientific satellites NASA ever launched into orbit aboard a single rocket.  The THEMIS mission aims to unravel the tantalizing mystery behind auroral substorms, an avalanche of magnetic energy powered by the solar wind that intensifies the northern and southern lights.  The mission will investigate what causes auroras in the Earth’s atmosphere to dramatically change from slowly shimmering waves of light to wildly shifting streaks of bright color.  Launch of THEMIS is scheduled for Feb. 15 aboard a Delta II rocket, with the launch service being conducted by the United Launch Alliance.  Photo credit: NASA/George Shelton KSC-07pd0343
