Castor 30
The Castor family of solid-fuel rocket stages and boosters built by Thiokol (now Northrop Grumman) 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. Versions Flown versions Castor 1 :The Castor 1 was first used for a successful suborbital launch of a Scout X-1 rocket on September 2, 1960. :It was long, in diameter, and had a burn time of 27 seconds. Castor 1 stages were also used as strap-on boosters for launch vehicles using Thor first stages, including the Delta-D. (A Delta-D was used in 1964 to launch Syncom-3, the first satellite placed in a geostationary orbit.) Castor 1 stages were used in 141 launch attempts of Scout and Delta rockets, only 2 of which were failures. They were also used on some thrust-assisted Thor-Agena launchers. The last launch usi ...

Thor-Agena
Thor-Agena was a series of orbital launch vehicles. The launch vehicles 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 launch vehicle to place a satellite into orbit. Missions Among other uses, the clandestine CORONA program used Thor-Agena from June 1959 until January 1968 to launch United States military reconnaissance satellites operated by the Central Intelligence Agency (CIA). During this program, Thor-Agena launch vehicles were used in 145 launch attempts, now known to have been part of satellite surveillance programs. Also, ''Alouette 1,'' Canada's first satellite, was launched on a Thor-Agena B. 1963 Mystery Cloud On 28 February 1963, a Thor-Agena launch vehicle car ...

Antares (rocket)
Development The NASA COTS award was for and Orbital Sciences expected to invest an additional $150 million, split between $130 million for the booster and $20 million for the spacecraft. A Commercial Resupply Service contract of $1.9 billion for eight flights was awarded in 2008. As of April 2012, development costs were estimated at $472 million. In June 2008, it was announced that the Mid-Atlantic Regional Spaceport, formerly part of the Wallops Flight Facility, in Virginia, would be the primary launch site for the rocket. Launch pad 0A (LP-0A), previously used for the failed Conestoga rocket, would be modified to handle Antares. Wallops allows launches which reach the International Space Station's orbit as effectively as those from Cape Canaveral, Florida, while being less crowded. The first Antares flight launched a Cygnus mass simulator. On December 10, 2009, Alliant Techsystems Inc. (ATK) test-fired their Castor 30 motor for use on the second stage of the Antar ...

Athena (rocket Family)
Athena was a 1990s Lockheed Martin expendable launch system which underwent several name changes in its lifetime. Development began at the Lockheed Corporation in 1993, where the design was known as the Lockheed Launch Vehicle. The name was subsequently changed to the Lockheed Martin Launch Vehicle when Lockheed merged with Martin Marietta. In 1997 the name was finally changed to Athena, and all of the launches after the demonstration flight in August 1995 were conducted using that name. Athena was retired from service in 2001, but in September 2010 Athena was added to NASA's Launch Services II contract. It was announced that it would be put back into production, with launches set to resume in 2012. All production had ceased by March 2017.

Atlas II
Atlas II was a member of the Atlas family of launch vehicles, which evolved from the successful Atlas missile program of the 1950s. The Atlas II was a direct evolution of the Atlas I, featuring longer first stage tanks, higher-performing engines, and the option for strap-on solid rocket boosters. It was designed to launch payloads into low earth orbit, geosynchronous transfer orbit or geosynchronous orbit. Sixty-three launches of the Atlas II, IIA and IIAS models were carried out between 1991 and 2004; all sixty-three launches were successes, making the Atlas II a highly reliable space launch system. The Atlas line was continued by the Atlas III, used between 2000 and 2005, and the Atlas V which is still in use.
