How many Atlas rockets were launched in 1957?
Atlas was a liquid propellant rocket burning RP-1 kerosene fuel with liquid oxygen in three engines configured in an unusual "stage-and-a-half" or "parallel staging" design: two outboard booster engines were jettisoned along with supporting structures during ascent, while the center sustainer engine, propellant tanks and other structural ...

The vernier engines, a trademark of Atlas vehicles, were designed to control the roll of the missile and trim its final flight velocity. The booster and vernier engines were all fed by liquid oxygen/RP-1 (kerosene) liquid propellant, and all engines were ignited at liftoff.
Jan 1, 2021 · Compiled by Kimble D. McCutcheon. Published 1 Jan 2021; Revised 3 Aug 2022. Abbreviations, Acronyms and Glossary. Atlas Overview. Atlas missiles used five Rocketdyne engines; two LR89 boosters, a single LR105 sustainer engine, and two LR101 vernier engines that provided roll control and fine targeting.
The two vernier engines were fed propellants from the sustainer engine turbopump and each produced about 1,000 lbT for as long as the sustainer engine operated. The Atlas Legacy. The Atlas launched satellites, space probes and four US astronauts (John Glenn, Scott Carpenter, Wally Shirra and Gordon Cooper).
Aug 21, 2002 · Each booster can produce a thrust of 285,500 pounds. The Atlas V second stage is comprised of either a one-engine or two-engine RL-10A Centaur upper stage. The Centaur burns a combination of liquid hydrogen and liquid oxygen. The one-engine Centaur can produce a thrust of 22,290 pounds. The two-engine Centaur can produce a thrust of 41,592 pounds.
Chemical rockets can be grouped by phase. Solid rockets use propellant in the solid phase, liquid fuel rockets use propellant in the liquid phase, gas fuel rockets use propellant in the gas phase, and hybrid rockets use a combination of solid and liquid or gaseous propellants.
Several Agena models were used as the program progressed, including the Agena-A, Agena-B, and Agena-D stages. Many space probes were launched on Atlas-Agena rockets. Including all nine Ranger lunar probes, the Mariner 2 and 5 Venus flyby spacecraft, the Mariner 3 and 4 Mars probes, and all five Lunar Orbiter missions.
