Spacecraft Launched In 2004
A spacecraft is a vehicle that is designed to fly and operate in outer space. 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 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 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 autonomously or telerobotically. Robotic spacecraft used to support scientific research are space prob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delta IV Heavy
The Delta IV Heavy (Delta 9250H) was an expendable heavy-lift launch vehicle, the largest type of the Delta IV family. It had the highest capacity of any operational launch vehicle in the world after the retirement of the Space Shuttle in 2011 until the Falcon Heavy debuted in 2018, and it was the world's third highest-capacity launch vehicle in operation at the time of its retirement in 2024. It was manufactured by United Launch Alliance (ULA) and was first launched in 2004. Delta IV Heavy was the last operating member of the Delta IV family, and its final flight was on 9 April 2024. It is succeeded by the Vulcan Centaur rocket. The Delta IV Heavy first stage consisted of a central Common Booster Core (CBC), with two additional CBCs as liquid rocket boosters instead of the GEM-60 solid rocket motors used by the Delta IV Medium+ versions. At lift-off, all three rocket engines would operate at full thrust, and 44 seconds later the central engine would throttle down to 5 ...

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 ... [...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, sports team, university society, society, military unit, or brand, 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 athletic nickname, nicknames. This is especially true when the team's nickname is something that is a living animal and/or can be anthropomorphism, 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 sport, athletic teams of the University of Alabama are nicknamed the Alabama Crimson Tide, Crimson Tide, while their mascot is an elephant named Big Al (mascot), Big Al. Team mascots may take the form of a logo, person, live animal, inanimate object, or a costumed c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Nanosat Program
The University Nanosat Program is a satellite design and fabrication competition for universities. It is jointly administered by the Air Force Office of Scientific Research (AFOSR), the Air Force Research Laboratory (AFRL), the American Institute of Aeronautics and Astronautics (AIAA), the Space Development and Test Wing and the AFRL Space Vehicles Directorate's Spacecraft Technology division. NASA's Goddard Space Flight Center was involved from the program inception through Nanosat-3. The UNP is a recurring competition that involves two phases. The first phase (Phase A) occurs as university teams initially respond to a solicitation posted by the UNP program or one of its partner organizations. The solicitation results in a competition for selection for that program cycle. Typically 10-11 awards are made during this initial phase. Grants are offered to the awardees to participate in a rigorous two-year process to design and develop their satellite concept. At the end of the two year ...

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 × 2 ...

Low Earth Orbit
A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around , while the farthest in LEO, before medium Earth orbit (MEO), have an altitude of 2,000 km, about one-third of the Earth radius, radius of Earth and near the beginning of the Van Allen radiation belt#Inner belt, inner Van Allen radiation belt. The term ''LEO region'' is 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 spaceflight, sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. No human spaceflights other than the lunar missions of the Apollo program (1968-1972) have gone beyond L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geocentric Orbit
A geocentric orbit, Earth-centered 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. Spa ...
