The Apollo 11 mission launched from the Kennedy Space Center (KSC) in Florida via the Marshall Space Flight Center (MSFC) developed Saturn V launch vehicle on July 16, 1969 and safely returned to Earth on July 24, 1969. Aboard the space craft were astronauts Neil A. Armstrong, commander; Michael Collins, Command Module (CM) pilot; and Edwin E. (Buzz) Aldrin Jr., Lunar Module (LM) pilot. With the success of Apollo 11, the national objective to land men on the Moon and return them safely to Earth had been accomplished. After 2½ hours of surface exploration, astronauts Neil Armstrong and Edwin Aldrin returned to the LM “Eagle” for rest, eating, and checkout of the vehicle in preparation for liftoff. The LM was a two part spacecraft. Its lower or descent stage had the landing gear, engines, and fuel needed for the landing. When the LM blasted off the Moon, the descent stage served as the launching pad for its companion ascent stage, which was also home for the two astronauts on the surface of the Moon. The LM was full of gear with which to communicate, navigate, and rendezvous. It also had its own propulsion system, and an engine to lift it off the Moon and send it on a course toward the orbiting CM. In this photograph, the ascent stage is seen back dropped by Earth just prior to its rendezvous with the CM.

S69-59547 (20 Nov. 1969) --- The seismometer reading from the impact made by the Lunar Module ascent stage when it struck the lunar surface. The impact was registered by the Passive Seismic Experiment Package which was deployed on the moon by the Apollo 12 astronauts. PSEP, which is a component of the Apollo Lunar Surface Experiments Package, will detect surface tilt produced by tidal deformations, moonquakes, and meteorite impacts. The LM's ascent stage was jettisoned and sent journeying toward impact on the moon after astronauts Charles Conrad Jr. and Alan L. Bean returned to lunar orbit and rejoined astronaut Richard F. Gordon Jr. in the Command and Service Modules. Information from the PSEP is transmitted to Earth through the ALSEP's central station and monitored by equipment at the Manned Spacecraft Center.

The Apollo 11 mission launched from the Kennedy Space Center (KSC) in Florida via the Marshall Space Flight Center (MSFC) developed Saturn V launch vehicle on July 16, 1969 and safely returned to Earth on July 24, 1969. Aboard the space craft were astronauts Neil A. Armstrong, commander; Michael Collins, Command Module (CM) pilot; and Edwin E. (Buzz) Aldrin Jr., Lunar Module (LM) pilot. With the success of Apollo 11, the national objective to land men on the Moon and return them safely to Earth had been accomplished. These sketches illustrate the steps taken when the astronauts left the Moon. After 2½ hours of surface exploration, astronauts Neil Armstrong and Edwin Aldrin returned to the Lunar Module (LM) “Eagle” for rest, eating, and checkout of the vehicle in preparation for liftoff. The ascent stage lifted off, using the descent stage as a launch pad. The ascent stage went into lunar orbit and moved in to dock with the orbiting CM “Columbia”. After Armstrong and Aldrin joined Collins in the CM, the engine of the LM ascent stage was fired to move it out of the same orbit.

This illustration is the Lunar Module (LM) configuration. The LM was a two part spacecraft. Its lower or descent stage had the landing gear, engines, and fuel needed for the landing. When the LM blasted off the Moon, the descent stage served as the launching pad for its companion ascent stage, which was also home for the two astronauts on the surface of the Moon. The LM was full of gear with which to communicate, navigate, and rendezvous. It also had its own propulsion system, and an engine to lift it off the Moon and send it on a course toward the orbiting Command Module.

The engine section, located at the bottom of SLS's massive core stage, will house the rocket's four RS-25 engines and be an attachment point for the two solid rocket boosters.

CAPE CANAVERAL, Fla. -- In high bay 4 of the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, a crane lowers segment 5 of the Ares I-X upper stage simulator segments onto segment 4, at top of the tall stack below. The upper stage simulator comprises 11 segments, each approximately 18 feet in diameter, that will be used in the test flight known as Ares I-X in 2009. The simulator segments will simulate the mass and the outer mold line. The upper stage accounts for nearly one-quarter of the total height of the Ares I. It will take the Ares I on the second phase of its journey from Earth, providing the guidance, navigation and control needed for the second phase of the Ares I ascent flight.

The Space Launch System (SLS) core stage is seen atop the mobile launcher inside High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on June 15, 2021. Teams with NASA’s Exploration Ground Systems and contractor Jacobs lifted and lowered the core stage – the largest part of the rocket – onto the mobile launcher, placing it in between the twin solid rocket boosters. The 188,000-pound core stage, with its four RS-25 engines, will provide more than 2 million pounds of thrust during launch and ascent, and coupled with the boosters, will provide more than 8.8 million pounds of thrust to send the Artemis I mission to space. Under the Artemis program, NASA will land the first woman and first person of color on the Moon, as well as establish a sustainable presence on the lunar surface in preparation for human missions to Mars.

The engine section, located at the bottom of SLS's massive core stage, will house the rocket's four RS-25 engines and be an attachment point for the two solid rocket boosters.

CAPE CANAVERAL, Fla. -- In high bay 4 of the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, a crane lowers the Ares I-X upper stage simulator segment 7 onto segment 6. The upper stage simulator comprises 11 segments, each approximately 18 feet in diameter, that will be used in the test flight identified as Ares I-X in 2009. The simulator segments will simulate the mass and the outer mold line. The upper stage accounts for nearly one-quarter of the total height of the Ares I. It will take the Ares I on the second phase of its journey from Earth, providing the guidance, navigation and control needed for the second phase of the Ares I ascent flight.

NASA engineers install test hardware for the agency's new heavy lift rocket, the Space Launch System, into a newly constructed 50-foot structural test stand at NASA's Marshall Space Flight Center. In the stand, hydraulic cylinders will be electronically controlled to push, pull, twist and bend the test article with millions of pounds of force. Engineers will record and analyze over 3,000 channels of data for each test case to verify the capabilities of the engine section and validate that the design and analysis models accurately predict the amount of loads the core stage can withstand during launch and ascent.

CAPE CANAVERAL, Fla. -- In high bay 4 of the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, a crane moves segment 5 of the Ares I-X upper stage simulator segments toward the tall stack behind it. Segment 5 will be placed on segment 4, at top of the tall stack. The upper stage simulator comprises 11 segments, each approximately 18 feet in diameter, that will be used in the test flight known as Ares I-X in 2009. The simulator segments will simulate the mass and the outer mold line. The upper stage accounts for nearly one-quarter of the total height of the Ares I.
