Seen here is a newly constructed liquid hydrogen (LH2) storage tank at Launch Pad 39B at NASA’s Kennedy Space Center in Florida on Oct. 1, 2021. With construction now complete, teams will focus on painting the tank next. The storage tank, capable of holding 1.25 million gallons of LH2, will be used to support future Artemis missions to the Moon and, eventually, Mars. Through Artemis, NASA will land the first woman and first person of color on the Moon, paving the way for a long-term presence in lunar orbit.

A memorial wreath placed in the Apollo-Saturn V Center of the Kennedy Space Center Visitor Complex on Wednesday, May 30, 2018, honors former NASA astronaut Alan Bean. He was the fourth person to walk on the Moon as lunar module pilot on Apollo 12 in November 1969. He went on to command the 59-day Skylab 3 mission in 1973. In the background is a large mural of a painting by Bean who became an accomplished artist after leaving NASA. He died in Houston on May 26, 2018, at the age of 86.

Artists used paintbrushes and airbrushes to recreate the lunar surface on each of the four models comprising the LOLA simulator. Project LOLA or Lunar Orbit and Landing Approach was a simulator built at Langley to study problems related to landing on the lunar surface. It was a complex project that cost nearly $2 million dollars. James Hansen wrote: "This simulator was designed to provide a pilot with a detailed visual encounter with the lunar surface; the machine consisted primarily of a cockpit, a closed-circuit TV system, and four large murals or scale models representing portions of the lunar surface as seen from various altitudes. The pilot in the cockpit moved along a track past these murals which would accustom him to the visual cues for controlling a spacecraft in the vicinity of the moon. Unfortunately, such a simulation--although great fun and quite aesthetic--was not helpful because flight in lunar orbit posed no special problems other than the rendezvous with the LEM, which the device did not simulate. Not long after the end of Apollo, the expensive machine was dismantled." (p. 379) Ellis J. White further described LOLA in his paper "Discussion of Three Typical Langley Research Center Simulation Programs," "Model 1 is a 20-foot-diameter sphere mounted on a rotating base and is scaled 1 in. = 9 miles. Models 2,3, and 4 are approximately 15x40 feet scaled sections of model 1. Model 4 is a scaled-up section of the Crater Alphonsus and the scale is 1 in. = 200 feet. All models are in full relief except the sphere." -- Published in James R. Hansen, Spaceflight Revolution: NASA Langley Research Center From Sputnik to Apollo, (Washington: NASA, 1995), p. 379; From Ellis J. White, "Discussion of Three Typical Langley Research Center Simulation Programs," Paper presented at the Eastern Simulation Council (EAI's Princeton Computation Center), Princeton, NJ, October 20, 1966.

KENNEDY SPACE CENTER, FLA. -- Apollo 11 Lunar Module Pilot Edwin E. "Buzz" Aldrin, Jr. and his wife, Lois, stand before a painting of an Apollo/Saturn V launch vehicle at the pad in the new Apollo/Saturn V Center (ASVC) at KSC prior to the gala grand opening ceremony for the facility that was held Jan. 8, 1997. The astronauts were invited to participate in the event, which also featured NASA Administrator Dan Goldin and KSC Director Jay Honeycutt. The ASVC also features several other Apollo program spacecraft component displays and multimedia presentations. The facility will be a part of the KSC bus tour that embarks from the KSC Visitor Center

CAPE CANAVERAL, Fla. -- At Space Launch Complex 17B on Cape Canaveral Air Force Station, the United Launch Alliance Delta II rocket that will launch NASA's Gravity Recovery and Interior Laboratory mission towers over the logos painted on the pad's structure of the companies comprising the launch team. The mobile service tower has been rolled away from the vehicle for launch. The "rollback" began at about 11:20 p.m. EDT Sept. 7. GRAIL will fly twin spacecraft in tandem around the moon to precisely measure and map variations in the moon's gravitational field. The mission will provide the most accurate global gravity field to date for any planet, including Earth. This detailed information will reveal differences in the density of the moon's crust and mantle and will help answer fundamental questions about the moon's internal structure, thermal evolution, and history of collisions with asteroids. The aim is to map the moon's gravity field so completely that future lunar vehicles can safely navigate anywhere on the moon’s surface. Launch is scheduled for 8:37:06 a.m. EDT Sept. 8.

KENNEDY SPACE CENTER, FLA. — NASA’s New Horizons spacecraft emerges from a cloud painted pink by the Atlas V rocket roaring through it after launch from Complex 41 on Cape Canaveral Air Force Station in Florida. Liftoff was on time at 2 p.m. EST. This was the third launch attempt in as many days after scrubs due to weather concerns. The compact, 1,050-pound piano-sized probe will get a boost from a kick-stage solid propellant motor for its journey to Pluto. New Horizons will be the fastest spacecraft ever launched, reaching lunar orbit distance in just nine hours and passing Jupiter 13 months later. The New Horizons science payload, developed under direction of Southwest Research Institute, includes imaging infrared and ultraviolet spectrometers, a multi-color camera, a long-range telescopic camera, two particle spectrometers, a space-dust detector and a radio science experiment. The dust counter was designed and built by students at the University of Colorado, Boulder. The launch at this time allows New Horizons to fly past Jupiter in early 2007 and use the planet’s gravity as a slingshot toward Pluto. The Jupiter flyby trims the trip to Pluto by as many as five years and provides opportunities to test the spacecraft’s instruments and flyby capabilities on the Jupiter system. New Horizons could reach the Pluto system as early as mid-2015, conducting a five-month-long study possible only from the close-up vantage of a spacecraft. Photo credit: NASA/Kim Shiflett
