| Title |
Communication Technology Satellite |
| Full Description |
The Communication Technology Satellite was launched from NASA's Kennedy Space Center, Florida, on January 17, 1976 and operated until October 1979. This high-powered spacecraft was the result of a five- year effort of international cooperation between NASA and Canada's Department of Communications. Canada designed and built the spacecraft and NASA tested, launched, and operated the CTS. The Canadians later renamed the spacecraft after the mythical Greek messenger god, Hermes. The transmitter improved 10-20 times the broadcast power of typical communication satellites of the era. With more power transmitted by the satellite, it was possible to use smaller and cheaper ground stations thus paving the way for applications such as direct broadcast television. The CTS is the second satellite designed to transmit high-quality color television. The first was the Application Technology Satellite (ATS), which was launched December 17, 1966. |

Hermes A-1 Test Rockets
| Title |
Hermes A-1 Test Rockets |
| Full Description |
The first Hermes A-1 test rocket was fired at White Sand Proving Ground (WSPG). Hermes was a modified V-2 German rocket, utilizing the German aerodynamic configuration, however, internally it was a completely new design. Although it did not result in an operational vehicle, the information that was gathered in the process contributed directly to the development of the Redstone rocket. |

| Full Description |
The Hermes A-1 rocket was designed by the U. S. Army after capturing the V-2 rocket from the German army at the conclusion of the Second World War. The Hermes A-1 is a modified V-2 rocket, it utilized the German aerodynamic configuration, however, internally it was a completely new design. This rocket was the first designed by the German Rocket Team at Redstone Arsenal in Huntsville, AL. |

M100: A Grand Design |

Majestic [ http://www.lhl.lib.mo.us/pubserv/hos/stars/welcome.htm ] on a truly cosmic scale, M100 [ http://bozo.lpl.arizona.edu/messier/m/m100.html ] is appropriately known as a Grand Design spiral [ http://antwrp.gsfc.nasa.gov/apod/ap961030.html ] galaxy. A large galaxy of over 100 billion or so stars with well defined spiral arms [ http://antwrp.gsfc.nasa.gov/apod/ap960409.html ], it is similar to our own Milky Way [ http://antwrp.gsfc.nasa.gov/apod/ap970315.html ]. One of the brightest members of the Virgo Cluster of galaxies [ http://bozo.lpl.arizona.edu/messier/more/virgo.html ] , M100 (alias NGC 4321) is 56 million light-years distant in the spring constellation of Coma Berenices [ http://www.astro.wisc.edu/~dolan/constellations/ constellations/Coma_Berenices.html ]. This Hubble Space Telescope image [ http://oposite.stsci.edu/pubinfo/PR/94/01.html ] of the central region of M100 was made in 1993 with the Wide Field and Planetary Camera 2. It reveals the bright blue star clusters [ http://antwrp.gsfc.nasa.gov/apod/ap980329.html ] and intricate winding dust lanes [ http://antwrp.gsfc.nasa.gov/apod/ap980116.html ] which are hallmarks of this class of galaxies [ http://hermes.astro.washington.edu:80/scied/astro/hubble/hubble.html ]. Studies of stars in M100 [ http://antwrp.gsfc.nasa.gov/apod/ap960110.html ] have recently played an important role in determining the size and age [ http://antwrp.gsfc.nasa.gov/diamond_jubilee/ debate_1996.html ] of the Universe. |

Spiral Galaxy NGC 1232
| Title |
Spiral Galaxy NGC 1232 |
| Explanation |
Galaxies [ ftp://crux.astr.ua.edu/web/goodies/data_resources/galaxies.text ] are fascinating not only for what is visible, but for what is invisible. Grand spiral [ http://antwrp.gsfc.nasa.gov/apod/ap980606.html ] galaxy NGC 1232 [ http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1997AAS...191.8203B&db_key=AST&high=34f6e1de7f27181 ], recently captured [ http://www.eso.org/outreach/press-rel/pr-1998/pr-14-98.html ] in detail by the new Very Large Telescope [ http://antwrp.gsfc.nasa.gov/apod/ap960901.html ], is a good example. The visible is dominated by millions of bright stars [ http://antwrp.gsfc.nasa.gov/apod/ap971018.html ] and dark dust [ http://antwrp.gsfc.nasa.gov/apod/ap961119.html ], caught up in a gravitational swirl of spiral arms rotating about the center. Open clusters [ http://antwrp.gsfc.nasa.gov/apod/ap980329.html ] containing bright blue stars can be seen sprinkled along these spiral arms, while dark lanes [ http://antwrp.gsfc.nasa.gov/apod/ap980116.html ] of dense interstellar dust [ http://antwrp.gsfc.nasa.gov/apod/ap980121.html ] can be seen sprinkled between them. Less visible, but detectable, are billions of dim normal stars and vast tracts of interstellar gas [ http://antwrp.gsfc.nasa.gov/apod/ap980301.html ], together wielding such high mass that they dominate the dynamics of the inner galaxy [ http://hermes.astro.washington.edu:80/scied/astro/hubble/hubble.html ]. Invisible are even greater amounts of matter in a form we don't yet know - pervasive dark matter [ http://xrtpub.harvard.edu/Xray/dark_matter.html ] needed to explain the motions [ http://www.astro.queensu.ca/~dursi/dm-tutorial/dm2.html ] of the visible in the outer galaxy. What's out there? [ http://antwrp.gsfc.nasa.gov/debate/debate98.html ] |

| Title |
Pearl and Hermes Reef, Hawaiian Island Chain |
| Description |
Pearl and Hermes Reef (28.0N, 176.0W) in the Hawaiian Island Chain, are seen with several small sandy islands, forming an atoll that caps a seamount on the long chain that extends some 1,500 miles northwestward from the more familiar Hawaiian Islands proper. Pearl and Hermes Reef lies about 100 miles southeast of Midway island. A reticulate network of coral patch reefs separates the lagoon into more or less isolated pools. |
