Spacecraft Launched In 2004
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters outer space, space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other Astronomical object, celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomous robot, autonomously or telerobotics, te ...

Delta IV Heavy
The Delta IV Heavy (Delta 9250H) is an Evolved Expendable Launch Vehicle, expendable heavy-lift launch vehicle, the largest type of the Delta IV family. It is the world's third highest-capacity launch vehicle in operation, behind NASA's Space Launch System and SpaceX's Falcon Heavy and closely followed by China Aerospace Science and Technology Corporation, CASC's Long March 5. It is manufactured by United Launch Alliance (ULA) and was first launched in 2004. ULA will retire the Delta IV Heavy in 2024. , two flights remain. The Delta IV Heavy consists of a central Common Booster Core (CBC), with two additional CBCs as liquid rocket boosters instead of the Graphite-Epoxy Motor, GEM-60 solid rocket motors used by the Delta IV Medium+ versions. At lift off, all three cores operate at full thrust, and 44 seconds later the center core throttles down to 55% to conserve fuel until booster separation. The boosters burn out at 242 seconds after launch and are separated as the core booster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sparky (Arizona State Mascot)
Sparky the Sun Devil is the official mascot of Arizona State University. Originally the ASU athletic teams' mascot was an owl, then became a "Normal" (because ASU was founded as a normal school). It was later changed to a bulldog in an attempt to make the school – Arizona State Teacher's College at the time – appear more in line with Yale and other universities that held a higher level of respect. The '' State Press'', the student newspaper, ran frequent appeals during the fall of 1946, urging the Bulldog to be replaced by the new Sun Devil. On November 8, 1946, the student body voted 819 to 196 to make the change. On November 20, as reported by the ''Arizona Republic'', the student council made it official. The following day, the first Arizona State team played as the Sun Devils. Two years later, Stanford Alum and Disney illustrator Berk Anthony designed "Sparky", a devil holding a trident (colloquially referred to as a pitchfork). Anthony is rumored to have based Sparky's fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mascot
A mascot is any human, animal, or object thought to bring luck, or anything used to represent a group with a common public identity, such as a school, professional sports team, society, military unit, or brand name. Mascots are also used as fictional, representative spokespeople for consumer products. In sports, mascots are also used for merchandising. Team mascots are often related to their respective team nicknames. This is especially true when the team's nickname is something that is a living animal and/or can be made to have humanlike characteristics. For more abstract nicknames, the team may opt to have an unrelated character serve as the mascot. For example, the athletic teams of the University of Alabama are nicknamed the Crimson Tide, while their mascot is an elephant named Big Al. Team mascots may take the form of a logo, person, live animal, inanimate object, or a costumed character, and often appear at team matches and other related events, sports mascots are of ...

Petey (satellite)
Petey (or 3CS-3) was a satellite, part of Three Corner Satellite (3CS) project, a three satellite ( Sparkie, Ralphie and Petey) student research project. It was designed and built by mostly undergraduate students at the New Mexico State University as part of the Air Force Research Laboratory's University Nanosat Program. It was responsible for communication system in 3CS project. Satellite was not completed in time for launch of 3CS on December 21, 2004, and later was donated to the National Air and Space Museum’s Steven F. Udvar-Hazy Center. The two other 3CS satellites Sparkie and Ralphie were launched 21 December 2004 on the first launch of Delta IV Heavy. The launch was a partial failure, and in particular the two 3CS satellites did not achieve orbit. Satellite carries name of New Mexico State University's mascot, Pistol Pete.

3 Corner Satellite
Three Corner Satellite (or 3CS, or 3CornerSat) consisted of three student-built microsatellites flying in formation. Primary mission objectives were to demonstrate formation flying, provide stereoscopic imaging of cloud formations, and demonstrate distributed and autonomous operations. A pair of spacecraft, Ralphie and Sparkie, was developed by the University of Colorado at Boulder and Arizona State University as part of the Air Force Research Laboratory's University Nanosat Program. A third satellite, Petey, developed by New Mexico State University was originally also part of the 3CS. The 3CS stack was originally slated for launch aboard the Space Shuttle in 2003, but after the Shuttle Columbia tragedy, mission organizers switched to the first launch of the Boeing Delta IV Heavy rocket. Due to a problem with the rocket during launch, the 3CS satellites on board, Sparkie and Ralphie, failed to achieve orbit. The satellites were to have been dropped off at a low 180 km × ...

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geocentric Orbit
A geocentric orbit or Earth orbit involves any object orbiting Earth, such as the Moon or artificial satellites. In 1997, NASA estimated there were approximately 2,465 artificial satellite payloads orbiting Earth and 6,216 pieces of space debris as tracked by the Goddard Space Flight Center. More than 16,291 objects previously launched have undergone orbital decay and entered Earth's atmosphere. A spacecraft enters orbit when its centripetal acceleration due to gravity is less than or equal to the centrifugal acceleration due to the horizontal component of its velocity. For a low Earth orbit, this velocity is about ; by contrast, the fastest crewed airplane speed ever achieved (excluding speeds achieved by deorbiting spacecraft) was in 1967 by the North American X-15. The energy required to reach Earth orbital velocity at an altitude of is about 36 MJ/kg, which is six times the energy needed merely to climb to the corresponding altitude.
