Recently released information has shed light on the secret URSALA, RAQUEL and FARRAH satellites, small signals-intelligence spacecraft operated under the U.S. National Reconnaissance Office’s Program 989. The Space Review reports that the satellites evolved from experimental hitchhikers into a more standardized system intended to provide radar-signal intelligence and location data for military forces.
Recently released information has brought new details to light about URSALA, RAQUEL and FARRAH, secret U.S. satellites that collected radar and other electronic signals from orbit. The Space Review reports that the spacecraft were part of Program 989, a National Reconnaissance Office-managed effort that developed small satellites first carried into space alongside larger spacecraft and later used to support military intelligence needs.
The satellites were small compared with dedicated reconnaissance spacecraft, described in the report as roughly the size of a large suitcase. Built by Lockheed Missiles and Space Company, they carried antennas that swept across the ground as the satellites spun in orbit. Their purpose was to collect electronic intelligence, or ELINT, including radar signals. They generally recorded what they detected for later transmission, though some could relay signals directly to a ground station.
The effort began with satellites known informally as “hitchhikers”, deployed from larger spacecraft. The report traces the program through several names: Program 11, or P-11, followed by P-770B and then Program 989 in 1965 or 1966. The satellites continued flying after the larger Program 770 signals-intelligence series ended, with its last launch in 1972.
By the 1970s, the intelligence community used the designation Mission 7300 for the collection of radar signals and their geolocation data by these low-Earth-orbit satellites. The source says the National Reconnaissance Office moved toward more standardized spacecraft with an operational purpose: furnishing information to military forces, rather than serving only senior national-level intelligence users. The newly disclosed material also includes information about previously secret payloads flown on space shuttles, according to The Space Review.
From National Intelligence to Military Support
The program’s reported evolution points to a change in how the United States used intelligence gathered from space. Rather than focusing solely on information for national leaders, Mission 7300 was intended to support tactical forces across the Army, Navy and Air Force. That shift matters because it links orbital signals collection to military operations and the practical task of identifying and locating radar emissions.
The spacecraft also show how intelligence agencies adapted satellite design to changing needs. Early satellites were often developed quickly to address new targets, and their payloads could be one-off designs. Later standardization sought to improve capability and operating life while reducing the number of satellites needed. The report describes this as bringing space-based electronic intelligence closer to the warfighter, though it does not quantify operational effects or detail specific missions.

How Program 989 Took Shape
The first “hitchhiker” was launched by the Air Force in 1963, beginning a program that, according to The Space Review, continued for more than four decades under changing names and designations. The small spacecraft were carried with larger satellites because their size, mass, power and cost were constrained. One recurring carrier was HEXAGON, a large photo-reconnaissance satellite; the source says HEXAGON missions launched from California between 1971 and 1986, with one failure, and often carried Program 989 subsatellites.
Early spacecraft were often short-lived. Their low orbits and large antennas increased atmospheric drag, and lifetimes of one to four years were typical, the report says. Some lasted longer: MABELI was still operating when it re-entered after seven years, while TOP HAT II was functioning when it re-entered after six. The Air Force Special Projects office, known as SAFSP, sought longer-lived, more capable satellites as electronics improved.
The program’s naming practices also reflected efforts to conceal its purpose. Earlier spacecraft had obscure names and references; managers later chose names associated with movie actresses to avoid hints about the satellites’ missions, according to the source. Names including URSALA, RAQUEL, FARRAH, GLORIA and CARRIE have only recently been declassified, with further information released shortly before the 2025 report.

Limits of the Newly Released Record
The available report does not provide a full account of each satellite’s launch date, payload, operating period or specific intelligence targets. Although it names URSALA, RAQUEL and FARRAH, the material supplied here does not establish which capabilities belonged to each spacecraft or how their missions differed.
The source says significant information was released in the two months before its article, but does not give a complete inventory of documents or explain the release process. It also does not specify which space shuttle missions carried the newly disclosed payloads. Those details remain unconfirmed in the material available here, as do the precise operational outcomes of the satellites’ collection.

Further Declassification Could Add Detail
The immediate development is the publication of additional historical information, rather than a new satellite launch or a change to a current program. The Space Review’s account indicates that recently released records may allow researchers to reconstruct more of Program 989’s history, including its relationship to larger reconnaissance missions and the evolution of its military role.
Further clarity depends on the release of additional records and technical descriptions. Readers should look for documentation that identifies individual spacecraft, dates, payload configurations and shuttle-carried systems. Until those records are available and assessed, claims about the specific capabilities or results of URSALA, RAQUEL and FARRAH should remain limited to what the published material supports.

Key Questions
What were the URSALA, RAQUEL and FARRAH satellites?
They were names associated with small, secret U.S. satellites in Program 989, which collected radar and other electronic signals from orbit, according to The Space Review.
What did the satellites collect?
The report says they gathered electronic intelligence, including radar signals and information used to locate those signals. Most often, they recorded data for later transmission to the ground.
Who managed Program 989?
The National Reconnaissance Office managed the program. The Air Force Special Projects office, or SAFSP, handled Mission 7300 among other projects.
Why were the satellites called hitchhikers?
Early spacecraft in the program were carried into orbit alongside larger satellites and deployed from them, rather than launched as the primary payload.
What is still unknown about these satellites?
The source material does not give a complete satellite-by-satellite account of launch dates, payloads, targets or operational results. It also does not identify the specific shuttle missions associated with the recently disclosed payload information.
