Apollo 15 Lunar Module
Launched on 26 July, 1971, Apollo 15 was the fourth Apollo mission to successfully land on the moon, and the first of the longer, more science-focused J Missions. Landing at Hadley–Apennine on the 30, Commander David Scott and Lunar Module Pilot James Irwin (Irwin on left) stayed on the moon's surface until 2 August, while Command Module Pilot Alfred Worden stayed in orbit, collecting a variety of data on the moon. Apollo 15 was the first mission to use the Lunar Roving Vehicle (on right), which allowed Scott and Irwin to travel farther from the Lunar Lander (center) than previously possible. On 4 August, the lunar orbiter departed from orbit at the end of Apollo 15's 74th lunar orbit. On the 5, Worden performed an EVA which lasted 39 minutes. This was the first of three deep-space EVAs, all performed during J Missions. The command module landed in the North Pacific Ocean on the 7, with the command module and crew being recovered by USS Okinawa. Apollo 15 was the longest Apollo mission, lasting for a total of 12 days and 7 hours, until Apollo 17, which lasted 12 days, 13 hours, and 52 minutes. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Project POSTAR was the first space experiment created entirely by members of the Boy Scouts of America. On September 12, 1992, Space Shuttle Endeavour mission STS-47 carried 10 Get Away Special (GAS) canisters. Amongst these GAS cansisters was G-102 sponsored by the Boy Scouts of America's Exploring Division in cooperation with the TRW Systems Integration Group, Fairfax, Virginia. The project was named Project POSTAR. (The name was a combination of the words "Post" and "Star"). |

Space Shuttle Enterprise
The Space Shuttle Enterprise (OV-101) was the first orbiter built in the Space Shuttle program. Designed for atmospheric test flights, it lacked both engines and a heat shield, making it unable to go to space. Rolled out on 17 September 1976, it was initially named Constitution, but was renamed following a large letter-writing campaign from Trekkies. Unlike its eponym, the USS Enterprise from the original Star Trek series, OV-101 never achieved spaceflight; originally intended to be refitted to become the second space-rated orbiter after Columbia, changes to the design of the Space Shuttle made it both simpler and cheaper to instead construct a new shuttle, Challenger, around a test article. It was later considered for refitting following the Challenger disaster, but it was instead decided to build a replacement, Endeavour, out of spare parts from the construction of Discovery and Atlantis. Enterprise flew a total of five times, from 12 August to 26 October, 1977. It was then flown to Marshall Space Flight Center in Alabama, where it was placed into the Saturn V dynamic test stand for the Mated Vertical Ground Vibration Testing, in order to test the Space Shuttle's launch stack. It was then used for a variety of fit checks at Kennedy Space Center and Vandenberg Air Force Base, between which it toured Europe and North America, including a showing at the 1984 Louisiana World Exposition. It was then moved to the Smithsonian Institution's National Air and Space Museum on 18 November 1985. It was then moved to its present location aboard the USS Intrepid museum ship on 12 December 2011. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Zond 6 was a formal member of the Soviet Zond program, and an unpiloted version of the Soyuz 7K-L1 crewed Moon-flyby spacecraft. It was launched on a lunar flyby mission on November 10, 1968, from a parent satellite (68-101B) in Earth parking orbit. The spacecraft carried a biological payload of turtles, flies, and bacteria. It also carried scientific probes including cosmic ray, micrometeoroid detectors, and photographic equipment. The mission was a precursor to a crewed circumlunar flight which the Soviets hoped could occur in December 1968, thus beating the American Apollo 8. However, after rounding the Moon on November 14, Zond 6 crashed on its return to Earth, due to a parachute failure when the parachute was detached from the capsule too early. |

Explosion on the Cygnus CRS Orb-3
On 28 October, 2014, Cygnus Orb-3 was launched at 22:22:38 UTC. 15 seconds after liftoff, one of the launch vehicle's AJ26 (modified NK-33s) ruptured, resulting in the craft falling. The mission was scrubbed eight seconds later at 22:23:01 UTC. The subsequent investigation found that the liquid oxygen turbopump exploded, severing nearby propellant lines. This resulted in a fire that damaged various engine components. The cause of the LOX turbopump's failure remains unknown. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Exoplanetary Circumstellar Environments and Disk Explorer (EXCEDE) is a proposed space telescope for NASA's Explorer program to observe circumstellar protoplanetary and debris discs and study planet formation around nearby (within 100 parsecs) stars of spectral classes M to B. Had it been selected for development, it was proposed to launch in 2019. The spacecraft concept proposed to use a 70 centimeter diameter telescope-mounted coronagraph called PIAA (Phase Induced Amplitude Apodized Coronagraph) to suppress starlight in order to be able to detect fainter radiation of circumstellar dust. Characterizing constitution of such disks would provide clues for planetary formation (mostly in habitable zones), while already existing exoplanets can be detected through their interaction with dust disk. The project's Principal Investigator is Glenn Schneider. |

Wernher von Braun with the Rocketdyne F-1 engines
Pictured here are two titans of spaceflight history: Dr. Wernher von Braun, one of the main figures of the early American space program and designer of both the Saturn V and V-2 rockets, and five (four visible) Rocketdyne F-1 engines, used on the Saturn V Dynamic Test Vehicle. Dr. von Braun's career is noted for a great number of achievements in human spaceflight, including the Apollo mission which successfully put human beings on the moon; nevertheless, it is burdened with the shadow of his activities in the Nazi Party, especially concerning his work on the V-2. The engines behind him, in addition to being immense, have the honor of being the only engines used to get humans to the moon, as of the time of writing. Developed in the late 1950s, the 8,400 kilograms (18,500 lb) engines are still the most powerful single combustion chamber liquid-propellant rocket ever made. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

A parking orbit is a temporary orbit used during the launch of a spacecraft. A launch vehicle follows a trajectory to the parking orbit, then coasts for a while, then engines fire again to enter the final desired trajectory. An alternative trajectory that is used on some missions is direct injection, where the rocket fires continuously (except during staging) until its fuel is exhausted, ending with the payload on the final trajectory. This technique was first used by the Soviet Venera 1 mission to Venus in 1961. |
