A time control is a mechanism in the tournament play of almost all two-player board games so that each round of the match can finish in a timely way and the tournament can proceed.
Ranger 1 was a prototype spacecraft launched as part of the Ranger program of uncrewed space missions. Its primary mission was to test the performance of those functions and parts necessary for carrying out subsequent lunar and planetary missions; a secondary objective was to study the nature of particles and fields in the space environment. Due to a launch vehicle malfunction, the spacecraft could reach only Low Earth orbit, rather than the high Earth orbit that had been planned, and was only able to complete part of its mission.
Mercury-Redstone 3, or Freedom 7, was the first United States human spaceflight, on May 5, 1961, piloted by astronaut Alan Shepard. It was the first crewed flight of Project Mercury. The project had the ultimate objective of putting an astronaut into orbit around the Earth and returning him safely. Shepard's mission was a 15-minute suborbital flight with the primary objective of demonstrating his ability to withstand the high g-forces of launch and atmospheric re-entry.
Mercury-Atlas 9 was the final crewed space mission of the U.S. Mercury program, launched on May 15, 1963, from Launch Complex 14 at Cape Canaveral, Florida. The spacecraft, named Faith 7, completed 22 Earth orbits before splashing down in the Pacific Ocean, piloted by astronaut Gordon Cooper, then a United States Air Force major. The Atlas rocket was No. 130-D, and the Mercury spacecraft was No. 20. As of 2023, this mission marks the last time an American was launched alone to conduct an entirely solo orbital mission.
Apollo 5, also known as AS-204, was the uncrewed first flight of the Apollo Lunar Module (LM) that would later carry astronauts to the surface of the Moon. The Saturn IB rocket bearing the LM lifted off from Cape Kennedy on January 22, 1968. The mission was successful, though due to programming problems an alternate mission to that originally planned was executed.
A countdown is a sequence of backward counting to indicate the time remaining before an event is scheduled to occur. NASA commonly employs the terms "L-minus" and "T-minus" during the preparation for and anticipation of a rocket launch, and even "E-minus" for events that involve spacecraft that are already in space, where the "T" could stand for "Test" or "Time", and the "E" stands for "Encounter", as with a comet or some other space object.
STS-37, the thirty-ninth NASA Space Shuttle mission and the eighth flight of the Space Shuttle Atlantis, was a six-day mission with the primary objective of launching the Compton Gamma Ray Observatory (CGRO), the second of the Great Observatories program which included the visible-spectrum Hubble Space Telescope (HST), the Chandra X-ray Observatory (CXO) and the infrared Spitzer Space Telescope. The mission also featured two spacewalks, the first since 1985.
STS-74 was the fourth mission of the US/Russian Shuttle-Mir Program, and the second docking of the Space Shuttle with Mir. Space Shuttle Atlantis lifted off from Kennedy Space Center launch pad 39A on 12 November 1995. The mission ended 8 days later with the landing of Atlantis back at Kennedy. It was the second in a series of seven straight missions to the station flown by Atlantis.
AS-103 was the third orbital flight test of a boilerplate Apollo spacecraft, and the first flight of a Pegasus micrometeroid detection satellite. Also known as SA-9, it was the third operational launch of a two-stage Saturn I launch vehicle.
American Country Countdown, also known as ACC, is a weekly internationally syndicated radio program which counts down the top 40 country songs of the previous week, from No. 40 to No. 1, according to the Billboard Country Airplay chart. The program premiered in 1973 and as of January 2006 is hosted by Kix Brooks. It is syndicated by Cumulus Media Networks.
C4 was a New Zealand television channel owned and operated by MediaWorks New Zealand. C4 was available on both digital terrestrial and satellite platforms and played music around the clock, including music from C4's sister radio division from The Rock, The Edge, The Breeze, More FM, George FM, Mai FM & The Sound. C4 also aired a lot of speciality music shows such as HomeGrown, Top 10/100, Video Hits, Fade To Black, Steel Mill, the UChoose40 and the Biggest Records Right Now. The channel was originally launched on Friday 3 October 2003 at 08:00pm as a re-branding of TV4 which had been broadcasting since 1997. On 1 May 2010, as C4 had been moving away from music programming since 2008, the jukebox side was split off and C4 launched a second C4 channel on Channel 9 called C4 2. C4 2 was only available on digital Freeview terrestrial and satellite platforms. At the end of 2010 an announcement was made that MediaWorks would again re-brand the current C4 channel as FOUR, which meant C4 2 would be converted to a music show as C4 was moved to its Channel 9 position. C4 shut down on Thursday 26 June 2014 at 01:00 am. It was replaced by The Edge TV the next day on Friday 27 June 2014 at 04:00 pm.
The Rocco A. Petrone Launch Control Center is a four-story building at NASA's Kennedy Space Center on Merritt Island, Florida, used to manage launches of launch vehicles from Kennedy Space Center Launch Complex 39. Attached to the southeast corner of the Vehicle Assembly Building, the LCC contains offices; telemetry, tracking, and instrumentation equipment; and firing rooms.
Countdown is a 1967 science fiction film directed by Robert Altman, based on the 1964 novel The Pilgrim Project by Hank Searls. Made before M*A*S*H, the film was subject to re-editing by the studio. Countdown stars James Caan and Robert Duvall as astronauts vying to be the first American to walk on the Moon as part of a crash program to beat the Soviet Union.
Randolph James "Komrade" Bresnik is a retired officer in the United States Marine Corps and an active NASA astronaut. A Marine Aviator by trade, Bresnik was selected as a member of NASA Astronaut Group 19 in May 2004. He first launched to space on STS-129, then served as flight engineer for Expedition 52, and as ISS commander for Expedition 53.
Launch commit criteria are the criteria which must be met in order for the countdown and launch of a Space Shuttle or other launch vehicle to continue. These criteria relate to safety issues and the general success of the launch, as opposed to supplemental data.
Kutonen (Sixth) is a Finnish general entertainment channel that replaced the music-video oriented The Voice TV in September 2012. Kutonen is very closely related to its Danish counterpart 6'eren, sharing its visual branding and much programming with it, as well as having close strategic connections to other brands owned and operated by SBS in other European countries.
A terminal countdown demonstration test (TCDT) is a simulation of the final hours of a launch countdown and serves as a practice exercise in which both the launch team and flight crew rehearse launch day timelines and procedures. In the specific case of a TCDT for the Space Shuttle, the test culminated in a simulated ignition and RSLS Abort. Following the simulated abort, the flight crew was briefed on emergency egress procedures and use of the fixed service structure slidewire system. On some earlier shuttle missions, and Apollo missions, the test would conclude with the flight crew evacuating the launch pad by use of these emergency systems, but this is no longer part of the test.
Yoshinobu Launch Complex (LC-Y) is a rocket launch site at the Tanegashima Space Center on Tanegashima. The site and its collection of facilities were originally built for the H-II launch vehicle and later used for H-IIA and H-IIB launches.
Soyuz TMA-07M was a spaceflight launched to the International Space Station in 2012 which transported three members of the Expedition 34 crew to the station. The Soyuz remained docked to the space station and served as an emergency escape vehicle for the Expedition 35 increment, before returning its crew to Earth in May 2013.
