List of Thor DM-21 Agena-B launches

Last updated

Thor DM-21 Agena-B or just Thor-Agena was a series of orbital launch vehicles. The rockets used the Douglas-built Thor first stage and the Lockheed-built Agena second stages. They are thus cousins of the more-famous Thor-Deltas, which founded the Delta rocket family. The first attempted launch of a Thor DM-21 Agena-B was in January 1959. The first successful launch was on 28 February 1959, launching Discoverer 17 . [1]

Cape Canaveral Space Force Station Military rocket launch site in Florida, USA

Cape Canaveral Space Force Station (CCSFS) is an installation of the United States Space Force's Space Launch Delta 45, located on Cape Canaveral in Brevard County, Florida.

PGM-17 Thor Intermediate Range Ballistic Missile (IRBM)

The PGM-17A Thor was the first operational ballistic missile of the U.S. Air Force (USAF). Named after the Norse god of thunder, it was deployed in the United Kingdom between 1959 and September 1963 as an intermediate-range ballistic missile (IRBM) with thermonuclear warheads. Thor was 65 feet (20 m) in height and 8 feet (2.4 m) in diameter. It was later augmented in the U.S. IRBM arsenal by the Jupiter.

Delta (rocket family) Rocket family

Delta is an American versatile family of expendable launch systems that has provided space launch capability in the United States since 1960. Japan also launched license-built derivatives from 1975 to 1992. More than 300 Delta rockets have been launched with a 95% success rate. Only the Delta IV Heavy rocket remains in use as of November 2020. Delta rockets are currently manufactured and launched by the United Launch Alliance.

KH-5 Argon

KH-5 ARGON was a series of reconnaissance satellites produced by the United States from February 1961 to August 1964. The KH-5 operated similarly to the Corona series of satellites, as it ejected a canister of photographic film. At least 12 missions were attempted, but at least 7 resulted in failure. The satellite was manufactured by Lockheed. Launches used Thor-Agena rockets flying from Vandenberg Air Force Base, with the payload being integrated into the Agena.

Atlas-Agena

The Atlas-Agena was an American expendable launch system derived from the SM-65 Atlas missile. It was a member of the Atlas family of rockets, and was launched 109 times between 1960 and 1978. It was used to launch the first five Mariner uncrewed probes to the planets Venus and Mars, and the Ranger and Lunar Orbiter uncrewed probes to the Moon. The upper stage was also used as an uncrewed orbital target vehicle for the Gemini crewed spacecraft to practice rendezvous and docking. However, the launch vehicle family was originally developed for the Air Force and most of its launches were classified DoD payloads.

Thor-Agena Rocket developed in United States

Thor-Agena was a series of orbital launch vehicles. The rockets used the Douglas-built Thor first stage and the Lockheed-built Agena second stages. They are thus cousins of the more-famous Thor-Deltas, which founded the Delta rocket family. The first attempted launch of a Thor-Agena was in January 1959. The first successful launch was on 28 February 1959, launching Discoverer 1. It was the first two-stage rocket to place a satellite into orbit.

Thor (rocket family) American rocket family

Thor was a US space launch vehicle derived from the PGM-17 Thor intermediate-range ballistic missile. The Thor rocket was the first member of the Delta rocket family of space launch vehicles. The last launch of a direct derivative of the Thor missile occurred in 2018 as the first stage of the final Delta II.

Thor-Ablestar American expendable launch system

The Thor-Ablestar, or Thor-Able-Star, also known as Thor-Epsilon was an early American expendable launch system consisting of a PGM-17 Thor missile, with an Ablestar upper stage. It was a member of the Thor family of rockets, and was derived from the Thor-Able.

SM-65D Atlas First operational version of the U.S. Atlas missile

The SM-65D Atlas, or Atlas D, was the first operational version of the U.S. Atlas missile. Atlas D was first used as an intercontinental ballistic missile (ICBM) to deliver a nuclear weapon payload on a suborbital trajectory. It was later developed as a launch vehicle to carry a payload to low Earth orbit on its own, and later to geosynchronous orbit, to the Moon, Venus, or Mars with the Agena or Centaur upper stage.

The Thor DSV-2 was a series of sounding rockets, test vehicles, and anti-satellite weapons derived from the Thor Intermediate-range ballistic missile. It was also used as the first stage of several Thor-derived expendable launch systems

Cape Canaveral Launch Complex 12

Launch Complex 12 (LC-12) at Cape Canaveral Space Force Station, Florida was a launch pad used by Atlas rockets and missiles between 1958 and 1967. It was the second-most southern of the pads known as Missile Row, between LC-11 to the south and LC-13 to the north. Along with Complexes 11, 13 and 14, 12 featured a more robust design than many contemporary pads, due to the greater power of the Atlas compared to other rockets of the time. It was larger, and featured a concrete launch pedestal that was 6 metres (20 ft) tall and a reinforced blockhouse. The rockets were delivered to the launch pad by means of a ramp on the southwest side of the launch pedestal.

Cape Canaveral Launch Complex 13 Former rocket launch site in Florida, USA

Launch Complex 13 (LC-13) was a launch complex at Cape Canaveral Space Force Station, the third-most southerly of the original launch complexes known as Missile Row, lying between LC-12 and LC-14. In 2015, the LC-13 site was leased by SpaceX and was renovated for use as Landing Zone 1 and Landing Zone 2, the company's East Coast landing location for returning Falcon 9 and Falcon Heavy launch vehicle booster stages.

Discoverer 24, also known as Corona 9018A, was an American area survey optical reconnaissance satellite which was launched in 1961 but failed to achieve orbit. It was a KH-5 Argon satellite, based on an Agena-B. It was the third KH-5 to be launched.

6555th Aerospace Test Group Military unit

The 6555th Aerospace Test Group is an inactive United States Air Force unit. It was last assigned to the Eastern Space and Missile Center and stationed at Patrick Air Force Base, Florida. It was inactivated on 1 October 1990.
