Scout X-2 was an American expendable launch system and sounding rocket which was flown twice in 1962. It was a four-stage rocket,based on the earlier Scout X-1,uprated first and third stages. It was a member of the Scout family of rockets.
The Scout X-2 used an Algol 1D first stage,instead of the earlier Algol 1B used on the Scout X-1. The third stage was the Antares 2A,a more powerful version of the Antares 1A used on earlier variants of the Scout rocket. The second and fourth stages were the same as those used on the Scout X-1;a Castor 1A and an Altair 1A respectively.
The first Scout X-2 was launched on a suborbital flight at 07:27 GMT on 29 March 1962. It flew from Launch Area 3 of the Wallops Flight Facility. The flight carried plasma and aeronomy experiments to an apogee of 6,291 kilometres (3,909 mi),and was successful. The second flight,launched on 26 April,carried the Solrad 4B satellite. It failed to reach orbit. Following this launch,the Scout X-2 was replaced by the upgraded Scout X-2M.
The Scout family of rockets were American launch vehicles designed to place small satellites into orbit around the Earth. The Scout multistage rocket was the first orbital launch vehicle to be entirely composed of solid fuel stages. It was also the only vehicle of that type until the successful launch of the Japanese Lambda 4S in 1970.
The Minotaur is a family of United States solid fuel launch vehicles derived from converted Minuteman and Peacekeeper intercontinental ballistic missiles (ICBM). They are built by Northrop Grumman via contract with the Air Force Space and Missile Systems Center's Space Development and Test Directorate (SMC/SD) as part of the Air Force's Rocket Systems Launch Program which converts retired Intercontinental Ballistic Missiles into space and test launch systems for U.S. government agencies.
The Castor family of solid-fuel rocket stages and boosters built by Thiokol and used on a variety of launch vehicles. They were initially developed as the second-stage motor of the Scout rocket. The design was based on the MGM-29 Sergeant,a surface-to-surface missile developed for the United States Army at the Jet Propulsion Laboratory.
Antares,known during early development as Taurus II,is an expendable launch system developed by Orbital Sciences Corporation and the Yuzhnoye Design Bureau to launch the Cygnus spacecraft to the International Space Station as part of NASA's COTS and CRS programs. Able to launch payloads heavier than 8,000 kg (18,000 lb) into low Earth orbit,Antares is currently the largest rocket operated by Northrop Grumman. Antares launches from the Mid-Atlantic Regional Spaceport and made its inaugural flight on April 21,2013.
This comparison of orbital launch systems lists the attributes of all individual rocket configurations designed to reach orbit. A first list contains rockets that are currently operational or in development;a second list includes all retired rockets. For the simple list of all conventional launcher families,see:Comparison of orbital launchers families. For the list of predominantly solid-fueled orbital launch systems,see:Comparison of solid-fueled orbital launch systems.
Minotaur IV,also known as Peacekeeper SLV and OSP-2 PK is an active expendable launch system derived from the LGM-118 Peacekeeper ICBM. It is operated by Northrop Grumman Innovation Systems,and made its maiden flight on 22 April 2010,carrying the HTV-2a Hypersonic Test Vehicle. The first orbital launch occurred on 26 September 2010 with the SBSS satellite for the United States Air Force.
The Proton-K,also designated Proton 8K82K after its GRAU index,8K82K,was a Russian,previously Soviet,carrier rocket derived from the earlier Proton. It was built by Khrunichev,and launched from sites 81 and 200 at the Baikonur Cosmodrome in Kazakhstan.
The NOTS-EV-2 Caleb,also known as NOTS-500,Hi-Hoe and SIP was an expendable launch system,which was later used as a sounding rocket and prototype anti-satellite weapon. It was developed by the United States Navy's Naval Ordnance Test Station (NOTS) as a follow-up to the NOTS-EV-1 Pilot,which had been abandoned following ten launches officially classified as failed missions. Two were launched in July and October 1960,before the cancellation of the project. Following cancellation,two leftover Calebs were used in the Satellite Interceptor Program (SIP),while three more were used as sounding rockets,under the designation Hi-Hoe. These derivatives flew until July 1962,when the Hi-Hoe made its final flight.
Scout X,also known as Cub Scout,was an American rocket which served as a prototype of the Scout,which was launched on a single test flight in 1960. It was used to test the configuration that later Scout rockets would use as well as two of the solid rocket motors that would be used on them.
Scout X-1 was an American expendable launch system and sounding rocket which was flown seven times between August 1960 and October 1961. Four orbital and three suborbital launches were made,with four of the launches resulting in failures.
The RM-90 Blue Scout II was an American sounding rocket and expendable launch system which was flown three times during 1961. It was used for two HETS test flights,and the launch of the Mercury-Scout 1 satellite for NASA. It was a member of the Scout family of rockets.
The RM-89 Blue Scout I was an American sounding rocket which was flown four times between January 1961 and April 1962. It was used for two HETS test flights,and a flight to investigate atmospheric re-entry. It was a member of the Scout family of rockets.
Scout X-1A was an American sounding rocket which was flown in 1962. It was a five-stage derivative of the earlier Scout X-1,with an uprated first stage,and a NOTS-17 upper stage.
Scout X-2M was an American expendable launch system which was flown three times between May 1962 and April 1963. It was a four-stage rocket,based on the earlier Scout X-2,but with an MG-18 upper stage instead of the Altair used on the X-2. It was a member of the Scout family of rockets.
The Scout X-2B was an American expendable launch system which was flown during 1963. It was a four-stage rocket,based on the earlier Scout X-2,but with an Altair 2A fourth stage in place of the Altair 1A used on the X-2. It was a member of the Scout family of rockets.
The Athena I,known as the Lockheed Launch Vehicle (LLV) at the time of its first flight and Lockheed Martin Launch Vehicle (LMLV) at the time of its second flight,was an American small expendable launch system which was used for four launches between 1995 and 2001. It is a member of the Athena family of rockets,along with the larger Athena II.

The Algol family of solid-fuel rocket stages and boosters built by Aerojet and used on a variety of launch vehicles. It was developed by Aerojet from the earlier Jupiter Senior and the Navy Polaris programs. Upgrades to the Algol motor occurred from 1960 till the retirement of the Scout launch vehicle in 1994.
A medium-lift launch vehicle (MLV) is a rocket launch vehicle that is capable of lifting between 2,000 to 20,000 kg by NASA classification or between 5,000 to 20,000 kilograms by Russian classification of payload into low Earth orbit (LEO). An MLV is between small-lift launch vehicles and heavy-lift launch vehicles.
