Project Space Track (1957-1961)

Project Space Track was a research and development project of the US Air Force, to create a system for tracking all artificial earth satellites and space probes, domestic and foreign. It was started at the Air Force Cambridge Research Center in Bedford, Massachusetts shortly after the launch of Sputnik I. Observations were obtained from some 160 sensors worldwide by 1960 and regular orbital predictions were issued to the sensors and interested parties. Space Track was the only organization that used observations from all types of sources: radar, optical, radio, and visual. All unclassified observations were shared with the Smithsonian Astrophysical Observatory. In 1961, the system was declared operational and assigned to the new 1st Aerospace Control Squadron as part of NORAD's Space Detection and Tracking System (SPADATS).

Establishment of Project Space Track

On 29 November 1957, shortly after the launch of Sputnik I on 4 October, two German expatriates, Dr. G. R. Miczaika (from Prussia) and Dr. Eberhart W. Wahl (from Berlin) formed Project Space Track (originally called Project Harvest Moon).[10]: 5  It was established in Building 1535 of the Geophysics Research Directorate (GRD), Air Force Cambridge Research Center, Laurence .G. Hanscom Field, Massachusetts. Both scientists had backgrounds in astronomy, although Dr. Wahl’s Ph.D. was in meteorology.

The mission of Space Track was to track and compute orbits for all artificial earth satellites, including both US and Soviet payloads, booster rockets, and debris. With the Soviet launch of Luna 1 on 2 January 1959, Space Track also started tracking space probes. The first major tracking effort was Sputnik II, containing the dog Laika, launched 3 November 1957.

An Electronic Support System Program Office, 496L, had been established in February 1959, with the program office at Waltham, Massachusetts under the direction of Col Victor A. Cherbak, Jr. By late 1959, the SPO had received additional responsibilities under the DoD Advanced Research Projects Agency (ARPA) to develop techniques and equipment for military surveillance of satellites. (27) Continuing development of Space Track was an integral part of this effort.

Since December 1958, Space Track had been the interim National Space Surveillance Control Center.(1) In December 1959, Space Track was moved to a new building, the National Space Surveillance Control Center (NSSCC), which was formally dedicated on 9 February 1960.Air Force Cambridge Research Center. Press release 60-P6. Bedford, MA: [February 1960]. The NSSCC was part of the Air Force Command and Control Development Division (known informally as C²D²), Air Research and Development Command. Dr. Harold O. Curtis of Lincoln Laboratory was the Director of the NSSCC. The name Space Track continued in use.

By 1960, there were about 70 people in the NSSCC involved in operations. (not 4)

Space Track continued tracking satellites and space probes until 1961. In late 1960, USAF Vice Chief of Staff General Curtis E. LeMay decided that the research and development system was ready to become operational. [11] : 8 

Eleven officers and one Senior Master Sergeant were selected to be the initial cadre of what became the 1st Aerospace Surveillance and Control Squadron. The initial cadre came to Space Track for training that started 7 November 1960. (The cadre was assigned to the new squadron on 6 March 1961.)

By mid-1961, the new squadron was operational under the USAF Aerospace Defense Force at Ent AFB, Colorado Springs, part of NORAD's Space Detection and Tracking System (SPADATS). The first Squadron Commander was Colonel Robert Miller.

In cavalier disregard of the Air Force Regulation on the subject, which specified clearly that unclassified nicknames, such as Space Track, should be two words (while codewords, such as CORONA (26), which were then themselves classified, should be only one word), ADC immediately decided to rename Space Track as Spacetrack and the name has stuck since – although the web site has returned to two words. (28)

Sensors

The Department of Defense had decided that the US Air Force should develop a command and control system for tracking satellites and that the US Army and US Navy should develop sensors for the purpose. US Navy development was at Dahlgren, Virginia and the US Army's program was at the Aberdeen Proving Ground, Maryland.

Drs. Miczaika and Wahl had assembled a list of facilities that could track satellites, either by monitoring telemetry or by using radar. The latter were mostly astronomical radio telescopes equipped with radars used in studying the moon (e.g., Jodrell Bank in England directed by Sir Bernard Lovell, Millstone Hill of Lincoln Laboratory in Massachusetts directed by Dr. Gordon Pettingill, and a radar at the Stanford Research Institute in California, directed by Walter Jaye). Two USAF radars, one on Shemya Island in the Aleutians and the other at Diyarbakır, Turkey, had been built to observe Soviet missile launches and became valuable for satellite tracking as well. A USA radar at the Laredo Test Site in Texas and one at Moorestown, New Jersey also participated later. Observations were received from the Royal Canadian Air Force research radar at Prince Albert, Saskatchewan, Canada. The Goldstone facility of the Jet Propulsion Laboratory was exceptionally helpful with observations of Soviet space probes.

In general, observations were in the form of time, azimuth and elevation (and range, from radars) as measured at the site or, in some cases, such as at Goldstone, in astronomical form (Right Ascension and Declination)[12] : 5–4 .Cite error: A <ref> tag is missing the closing </ref> (see the help page).: 3 

On rare occasions, the observations were purely verbal. For example, individuals on ships, planes, and islands in the Carribbean reported sightings of the decay of satellite 1958 β (h), although one aircraft was able to provide a detailed observation because the navigator happened to be completing a celestial fix at the exact time Cite error: A <ref> tag is missing the closing </ref> (see the help page).
