Deep Space Program Science Experiment.....U.S., program. See CLEMENTINE.

Deep Space Station.....U.S., organization, NASA, large radar/radio dishes for tracking and communication with deep space probes. Each Dish as a unique designation. Also known as DSS.

       The Sites at Goldstone, Madrid and Canberra are the three primary deep space sites, so-called Deep Space Communications Complexes (DSCCs). The antennas there (DSSs) are mostly actively managed for deep space mission support. Also at each DSCC is a Signal Processing Center (SPC). DSS-71 (MILA) at Merritt Island (FLA) is the DSN Launch Support Facility. The rest of DSS designators assigned to cooperative sites for book-keeping purposes - e.g. when JPL received tracking of Voyager from the Parkes observatory in Australia, the DSS-49 tag was added. Some of the primary site DSSs noted on the earlier list are retired, and inactive or used for research or teaching. There are some that are curiously not on the list, for instance the Stanford Radio Observatory antenna that we used to try to detect UHF signals from Mars 98.

       Further, the antennas have different roles. As an example, each site has on 70-meter antenna (DSS-14, DSS-63, and DSS-43), and one arrayed set of 34-meter Beam Wave Guide antennas (DSS-24, DSS-54, and DSS-34). DSS-15, DSS- 65, and DSS- 45 are 34-meter Hi Efficiency antennas. DSS-16, DSS-66, and DSS-26 are 26-meter antennas (purpose I don't know). They were originally built to track Apollo.

       DSS-12 at Goldstone (ECHO site) is used by the Apple Valley schools as a teaching instrument for radio astronomy. DSS-42 and DSS-62 are or in the process of being dismantled. The earliest of the Goldstone sites (PIONEER), is a National Historic Landmark. DSS-28 has been mothballed.

DEEP IMPACT MISSION.....U.S., NASA, satellite, scientific, heliocentric. The Deep Impact mission will send an 1100 lb (500 kg) copper projectile crashing into the surface of a comet at more than 20,000 miles per hour, creating a huge crater and revealing never before seen materials and the internal composition and structure of a comet. This will be the first experiment to probe deep beneath the surface of a comet and will permit a variety of instruments, both onboard the spacecraft and at ground-based and space-based observatories, to study the resulting debris and pristine interior material. On July 3, 2005, the spacecraft will be about 550,000 miles from Comet P/Tempel 1 when the impactor will be released. The following day the impactor will forcefully strike the sunlit side of the comet nucleus, forming a crater roughly 25 feet deep and 325 feet wide, sending material from the interior of the nucleus into space and vaporizing the projectile. Sixty seconds before impact, the spacecraft will begin recording closeup images of the comet surface and then, from a distance of 6,200 miles, will record the actual impact. At 600 seconds after impact, the spacecraft will be about 2,500 miles from the nucleus and observations of the crater will begin. The spacecraft's closest approach to the nucleus will be 435 miles. At 3,000 seconds after impact the spacecraft will begin sending impactor and flyby images back to Earth. The primary science data will be returned to Earth within 10 hours of the encounter, with a 28-day supplemental data return period. The Deep Impact mission is managed for NASA by the Jet Propulsion Laboratory, Pasadena, CA. Ball Aerospace and Technologies Corporation, Boulder, CO, is responsible for all flight hardware.

Discovery Program.....U.S. NASA, program. NASA's Discovery Program gives scientists the opportunity to dig deep into their imaginations and find innovative ways to unlock the mysteries of the universe. The program's prime objective is to enhance the understanding of the solar system, both historically and as it is today, by exploring the planets, their moons and other small bodies. The goal is to launch many, smaller Missions that perform focused science with fast turnaround times with a cost for the entire mission of less than $299 million. The intent is to have a mission launch every 12 to 24 months. According to NASA, “In response, the space science community has formulated the following Fundamental Questions, which lie at the core of gaining this understanding:

- How did the universe, galaxies, stars and planets evolve?

- How can our exploration of the universe and our solar system revolutionize our understanding of physics, chemistry and biology?

- Does life in any form exist elsewhere than on planet Earth?

- Are there Earth-like planets beyond our solar system?

- How can we utilize knowledge of the Sun, Earth and other planetary bodies to improve the quality of life on Earth? What cutting edge technologies must we develop to conduct our research in the most productive, economical and timely manner? “

Eight Missions have been chosen for the Discovery Program to date. The following I've have been launched:

- Discovery-1 NEAR: 1996-008A, 1996/2/17

- Discovery-2 MARS PATHFINDER: 1996-0068A,1996/12/04,

DoD Designation.....

DoD Designation

       U.S. DoD, Project/Program/System designation and identification used by U.S. Army, U.S. Air Force. Started in the 1940's and continues through 2000's. U.S. Project identification used by U.S. Army, and later by the U.S. Air Force in the 1940's and 1950's, was the MX or Material Experimental designation. Starting in the early 1950's, the Air Force started to assign numerical designations to complete weapons systems, support systems and general categories of activity (like research studies). The designations initially was WS, SS, OS, RS. Starting in the 1960's System Management Code (SMC) was introduced and is currently used. The SMC gradually replaced WS, SS, OS, and RS. The system numbers [see column labeled (2) in table below] are still is use today. Weapons/support systems, which received a number in the original designation system retained this number as their SMC. Other weapons use newly assigned numbers, including numbers, which had been originally assigned to a different system, which is now out of service. These numbers are sometimes related to other designations of the weapon (e.g. the LGM-118A Peacekeeper ICBM has SMCs in the 118 series). Also being used were the prefix AFP, Project, Program, Code, and no prefix.

Note: The dash between the designator and the number is often omitted.

(1) designators:

MX - Material Experimental (Used in the 1940's and 1950's)

WS - Weapons System (Used in the 1950's)

SS - Support System (Used in the 1950's)

OS - Operational Support (Used in the 1950's)

RS - Research Support (Used in the 1950's)

AFP - Air Force Program (Gradually replaced WS, SS, OS, and RS) There are some numbers in my "database", which are associated with USAF projects, but don't seem to fall into the "MX", "WS/SS/RS" and "System" designation lists. Instead the numbers are usually just prefixed with "Project", "Program", "AFP" (Air Force Program) or not at all. It is possible that some of the numbers (especially the 3-digit ones) actually belong to the "System" numbering series of the preceding section.

Program - (Gradually replaced WS, SS, OS, and RS)

Project - (Gradually replaced WS, SS, OS, and RS)

Code - (Gradually replaced WS, SS, OS, and RS) (Unofficial but used in the literature)

(None) - (Gradually replaced WS, SS, OS, and RS)

(2) three-digit system number. Blocks of numbers are assigned to different general system categories as follows: Within each block, the initial numbers were probably assigned sequentially. Later, however, the numbers were apparently arbitrarily assigned. The n99 numbers seem to have been used for general studies. Numbers, which had become obsolete, were often reassigned to new systems. Systems in the 100, 200 and 300 blocks originally received "WS" designators, while systems in the 400, 500 and 600 blocks were designated "SS", "OS" and "RS", respectively. This applies to 3 digit numbers carried over from the MX, WS, OS, SS, RS designation. However, the prefixes were not always consistently used, and often completely omitted. Many other exceptions exist. For more detailed explanation, see reference

100 - 199: Strategic Systems

200 - 299: Air-Defense Systems

300 - 399: Tactical Systems

400 - 499: Support Systems

500 - 599: Operational Support

600 - 699: Research/Experimental Support

(3) suffix letter, was usually an "A" for weapons systems and an "L" for support systems (including reconnaissance). If the same system number was assigned to different actual projects or activities, subsequent letters would be used (e.g., "B", "C", ..., or "M", "N", ..., respectively). The use of suffixes was not entirely consistent: The suffix letters in SMCs are not assigned sequentially. Instead, some letters are mostly used for a specific purpose. Examples are
- "E": Usually designates the engine of an airborne weapon system
- "Z": Used to designate all versions of a weapon system (as opposed to a specific version)

Other terms used include DoD Project Designation, DoD System Designation,

DOD Missile and satellite Designation

       U.S., Military. In 1963 the current system of alpha numeric designation for U.S. military missiles, rockets, drones and probes, was established, and is contained in DOD Publication 4120.15-L. Satellites were added in 1990. Only those vehicles relative to this document will be listed. Each vehicle is designated by a letter/number combination as follows:
