The Saturn V reached 400 feet per second (120 m/s) at over 1 mile (1,600 m) in altitude. Much of the early portion of the flight was spent gaining altitude, with the required velocity coming later. The Saturn V broke the sound barrier at just over 1 minute at an altitude of between 3.45 and 4.6 miles (5.55 and 7.40 km). At this point, shock ...
A launch status check, also known as a "go/no go poll" and several other terms, occurs at the beginning of an American spaceflight mission in which flight controllers monitoring various systems are queried for operation and readiness status before a launch can proceed.
The American Saturn MLV family of rockets was proposed in 1965 by NASA as successors to the Saturn V rocket. [65] It would have been able to carry up to 160,880 kg (354,680 lb) to low Earth orbit. The Nova designs were also studied by NASA before the agency chose the Saturn V in the early 1960s [ 66 ] Nova was cancelled in 1964 and had reusable ...
This is roughly twice that of NASA's Saturn V (7,750,000 lbf (34.5 MN) [28]) which flew between 1967 and 1973; more than NASA's SLS, which produced 8,800,000 lbf (39 MN) of thrust at liftoff in 2022; and well above the 10,000,000 lbf (44 MN) of thrust from the 30 engines that powered the Soviet Union's N1 rocket between 1969 and 1972.

A Saturn V is carried atop the ML-1 in the lead-up to Apollo 11. The first launch from the Mobile Launcher Platform-3 (MLP-3) (formerly called the Mobile Launcher-1 or ML-1) was the maiden flight of the Saturn V, and the first launch from LC-39, Apollo 4. Following this, it was used for two crewed Apollo launches: Apollo 8 and Apollo 11.
During launch, the Saturn V second stage experienced a potentially serious malfunction when the center of its five engines shut down two minutes early. The remaining engines on the second and third stages were burned a total of 34 seconds longer to compensate, and parking orbit and translunar injection were successfully achieved.
Grasshopper was an experimental technology-demonstrator, suborbital reusable launch vehicle (RLV), a vertical takeoff, vertical landing (VTVL) rocket. [34] The first VTVL flight test vehicle—Grasshopper, built on a Falcon 9 v1.0 first-stage tank—made a total of eight test flights between September 2012 and October 2013. [ 35 ]
