Ralphie (satellite)
Ralphie (or 3CS-2) was a satellite, part of the Three Corner Satellite (3CS) project, a three satellite ( Sparkie, Ralphie, Petey) student research project. It was designed and built by mostly undergraduate students at the University of Colorado Boulder as part of the Air Force Research Laboratory's University Nanosat Program. Ralphie was responsible for imaging and End-to-End Data Systems in the 3CS project. The satellite carries the name of CU Boulder's mascot, Ralphie. Ralphie was launched on the first launch of the Delta IV Heavy rocket configuration, along with 3CS-1, "Sparkie", but failed to achieve orbit due to a problem with the rocket during launch.

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] |

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. Previous winners of the competition were the University of Georgia Small Satellite Research Laboratory's MOCI Satellite, Michigan Technological University's Oculus-ASR, Cornell University's Cornell University Satellite (CUSat), University of Texas at Austin's Formation Autonomy Spacecraft with Thrust, Relnav, Attitude, and Crosslink (FASTRAC) for Nanosat-3 and the joint 3 Corner Satellite (3CS) project by the University of Colorado at Boulder, Arizona State University and New Mexico State University ...

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.

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.
