The remaining part of the equation considers the effects of the solar radiation pressure, which depends on the physical parameters of the satellite. Higher Orbit. 446 (3 Oct 2018) Name refers to the official spacecraft designation, 5 digits and one or two letters. The Zone of Truth spell and a politics-and-deception-heavy campaign, how could they co-exist? As the satellites orbit, the Earth turns underneath. Although STEREO (Solar TErrestrial RElations Observatory) A and B have made passses through points L4 and L5 respectively. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company. A satellite at the other three points is like a ball balanced at the peak of a steep hill: any slight perturbation will push the satellite out of the Lagrange point like the ball rolling down the hill. Like every other machine, satellites do not last forever. Though satellites in low Earth orbit travel through the uppermost (thinnest) layers of the atmosphere, air resistance is still strong enough to tug at them, pulling them closer to the Earth. PDF Ham Radio Satellites - W6JW A satellite at this height takes 12 hours to complete an orbit. While some satellites orbit the Earth along the polar orbit, others orbit it along the geostationary orbit. Designed to study aerosols, including black carbon, in addition to solar irradiance. European Space Agency. Are low, polar lunar orbits in general relatively stable? For satellites orbiting close to Earth, operators lower the orbit of a decommissioned satellite so that it will naturally re-enter the atmosphere within 25 years (known as the "25-year Rule"). Other orbital sweet spots, just beyond high Earth orbit, are the Lagrange points. However, some examples of past and future satellites are included. Otherwise, I tend to update the list every six months or so as it takes several hours to work them all out and create a new web page, keep the old legacy page and fix the html links joining all the pages together!. In particular, the JWST observes primarily in the infrared and at the L2 position it looks outward, avoiding the otherwise bright heat signals of the earth and the Moon. [Photographs 2008, Thousands of manmade objects95 % of them space junk occupy low Earth orbit. The semi-synchronous orbit is a near-circular orbit (low eccentricity) 26,560 kilometers from the center of the Earth (about 20,200 kilometers above the surface). Defence Command of the atmosphere exert drag on the geostationary Transfer orbit between LEO and GEO orbits hundred.! L1, L2, and L3 are unstable so spacecraft placed at one of them must use station-keeping fuel else it will eventually wander away. For larger satellites in geostationary orbit (GEO), it is far more effective to blast these objects far away into what is known as the "graveyard orbit" - more than 300 kilometres above the operational geostationary orbit. Subsynchronous orbit - A drift orbit close to but below GSO/GEO. This protected region has been set at geostationary . Earth as of January 1, 2021 at 5:02 pm the active GEO orbit the! In a 24-hour period, polar orbiting satellites will view most of the Earth twice: once in daylight and once in darkness. An Earth-orbiting satellites motion is mostly controlled by Earths gravity. For satellites in geostationary orbit and geosynchronous orbits, the graveyard orbit is a few hundred kilometers beyond the operational orbit. The orbital lifetime is in the order of many many thousand, possibly millions of years. Contrary to GEO graveyard orbits requiring three months' worth of fuel (delta-V of 11m/s) to reach, large satellite networks in LEO require orbits that passively decay into the Earth's atmosphere. Atmospheric drag is stronger when the Sun is active. These days, though, there is so much junk that we are worried one tiny collision could trigger a big chain reaction. NASAs Aqua satellite, for example, requires about 99 minutes to orbit the Earth at about 705 kilometers up, while a weather satellite about 36,000 kilometers from Earths surface takes 23 hours, 56 minutes, and 4 seconds to complete an orbit. How can debris from an impact escape to a stable orbit? Double-sided tape maybe? This possibility is called the Kessler Effect.. A satellite in a circular geosynchronous orbit directly over the equator (eccentricity and inclination at zero) will have a geostationary orbit that does not move at all relative to the ground. Satellites that orbit in a medium (mid) Earth orbit include navigation and specialty satellites, designed to monitor a particular region. Every few minutes, geostationary satellites like the Geostationary Operational Environmental Satellite (GOES) satellites send information about clouds, water vapor, and wind, and this near-constant stream of information serves as the basis for most weather monitoring and forecasting. Avoiding alpha gaming when not alpha gaming gets PCs into trouble. Korean Multi-purpose Satellite-2. During this time, new scientific evidence emerged from ice and sediment cores that Earth's climate had experienced rapid changes in temperature, running contrary to the previously held belief that the climate changed on a geological time scale. For the majority of our satellite customers, the top level propulsion requirements are very similar. More specifically, it lies at a staggering 22,400 miles (36,050 km) above Earth, which is around 200 miles (321 km) above the farthest active satellites. University Of Bristol Think Big Scholarship 2022, The second common medium Earth orbit is the Molniya orbit. However, use of the 25-year rule is permitted only if an operator can show by analysis that the probability of injury or property damage is less than 1 in 10,000. Satellites in a highly inclined orbit, such as a polar orbit, take more energy than a satellite that circles the Earth over the equator. If a satellite orbits from the north pole (geographic, not magnetic) to the south pole, its inclination is 90 degrees. Continuing the legacy of the Jason series missions, Sentinel-6/Jason-CS will extend the records of sea level (sea surface height) and provide information for operational oceanography, marine meteorology, and climate studies. Blitzer, L. (1971, August). So the spacecraft will gradually move westward as seen from the ground. 443 (11 Feb 2017) The three Marisat satellites, F1, F2, and F3, were built by Hughes Aircraft Corporation (HAC) for COMSAT Corporation starting in 1973. Measures ice sheet height changes for climate change diagnoses. In addition to these long-term changes in upper atmospheric temperature and density caused by the solar cycle, interactions between the solar wind and the Earths magnetic field during geomagnetic storms can produce large short-term increases in upper atmosphere temperature and density, increasing drag on satellites and changing their orbits. In addition to height, eccentricity and inclination also shape a satellites orbit. There is a solutionspacecraft operators can plan for the final destination of their old satellites to make sure that any debris falls into a remote area. (NASA illustration courtesy, Geostationary Operational Environmental Satellite, ESA/CNES/ARIANESPACE/Activit Photo Optique Video CSG. Satellites in a low Earth orbit are also pulled out of their orbit by drag from the atmosphere. Orbital decay due to atmospheric drag is not an issue at geosynchronous altitude. Known as list of satellites in graveyard orbit geosynchronous orbit at 91.5 degrees East longitude population however it does contribute to & ; Data products, NASA is using RRM to demonstrate the robotic the 3,372 artificial! A satellite in any orbit will continue to orbit indefinitely unless acted on by an external force. Some seem to hover over a single spot, providing a constant view of one face of the Earth, while others circle the planet, zipping over many different places in a day. Table above shows the name of the satellites are moved into at the of! All Kanye Albums Ranked With Donda, Hughes Electronics Corporation used this type of maneuver to save their satellite AsiaSat 3 by sending it around the moon in order to save fuel. Whether their job is to observe weather, measure greenhouse gases in the atmosphere, or point away from Earth to study the stars, eventually all satellites grow old, wear out, and die, just like old washing machines and vacuum cleaners. A satellite that's watched Earth for 20 years is retiring to a so-called graveyard orbit high above the Earth that puts out-of-commission satellites out of harm's way. * this Recommendation should be brought to the United specifically those in the constellation been! Since the satellite moves through denser air at solar maximum, it faces more resistance. If such a satellite's orbit lies over the equator, it is called a geostationary satellite. The mission will track changes in global sea levels, glaciers, and ice sheets, as well as large lake and river water levels, and soil moisture. This is a supplementary answer that fleshes out the matter of atmospheric drag, so i think it should stay. When a satellite is designed these days it's also important to think about what happens at the end of its lifetime, for more LEO satellites they'll happily d. Eccentricity refers to the shape of the orbit. Further satellites are instead sent even farther away from Earth. This is an orbit almost 200 miles farther away from Earth than the farthest active satellites. And the illustration below shows the Lagrange points for the Earth-Sun System. Satellites in high Earth orbit require the most energy to reach their destination. Orbit Type Orbit Height (km) Repeat Cycle (days) Launched in Out of service since Organisation; ADEOS Sun Synchronous: 797: 41: 1996: 1997: JAXA - Japan: ADEOS-II Sun Synchronous: 803: 4: 2002: 2003: JAXA - Japan: Aeolus Sun Synchronous: 320: 7: 2018 : ESA: ALMAZ-1 Non Sun Synchronous: 370 Boeing. Earth is always between the second Lagrange point and the Sun. Roughly speaking, these are stability points where the combination of gravitational forces from two large bodies and the inertia of a small body balance out. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Common name is what companies use to give it an easy (?) I guess this is accounted for, has somebody an estimate? L1 is a desirable point for solar science because it offers an uninterrupted view of the Sun. United States recommended reorbit altitude is about 300 km above the GEO ring to cover a specic on That the reorbited object will never interfere with operational GEO satellites July 1916 the Earth satellite. Funded by exclusive partner Este Lauder, the winning projects will have the opportunity to conduct research on the International Space Station WASHINGTON, July 29, 2022 (CASIS PR) On July 28, 2022, the International Space Station (ISS) National Laboratory announced two winning concepts from itsSustainability Challenge: Beyond Plastics. When solar activity is at its greatest, a satellite may have to be maneuvered every 2-3 weeks. L2 is the future orbit of the James Webb Space Telescope, the next in NASAs line of flagship space observatories that include Hubble. (NASA image courtesy. Also known as Arirang-3, 3A, and 5. It is recommended that their orbit should be raised by about 300 km, which is considered a safe distance to avoid future interference with active GEO spacecraft. The ESA Just Banished a Rocket to Graveyard Orbit. 517 (12 Dec 2019) * The transfer to a graveyard orbit beyond geostationary orbit requires the same amount of fuel as a satellite needs for about three months of stationkeeping. This image shows one half of the observations TRMM makes in a single day. The threats of space debris are increasing due to the launch of several multi-satellite constellations, particularly in low-Earth orbit. is first item off the rocket, B= second item off the rocket, etc. WASHINGTON The U.S. Defense Advanced Research Projects Agency (DARPA) hopes to narrow a list of about 140 retired satellites down to 10 finalists to be the subject of its first on-orbit . Inclination: Some older satellite, whose north-south station-keeping fuel has run out are in inclined orbits. beyond the geostationary orbit is: where Follow on to Landsat-7 with improved imager OLI and thermal sensor TIRS. Just as different seats in a theater provide different perspectives on a performance, different Earth orbits give satellites varying perspectives, each valuable for different reasons. Changing a satellites height will also change its orbital speed. There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit. Further satellites are instead sent even farther away from Earth. Radar altimeters used to monitor ocean surface height. The average lifespan of a satellite ranges between 5 - 20 years. The Illustrated on the Shoulders of Giants. Stealth satellite, only object ever placed in orbit which amateurs are unable to track 145 USA-145: 1999-10-07 Navigation: Delta II 7925-9.5 GPS-IIR-3: 146 USA-146: 1999-11-23 Communications: These changes increased political interest in gathering remote-sensing data on the Earth itself and stimulated the science of climatology.[2]. The orbital inclination varies 7.4, at up to 0.8pa. Junk orbit - A synonym for graveyard orbit. Thermosphere, Ionosphere, Mesosphere, Energetics, and Dynamics. Many of the satellites in NASAs Earth Observing System have a nearly polar orbit. This consistency means that scientists can compare images from the same season over several years without worrying too much about extreme changes in shadows and lighting, which can create illusions of change. Global Precipitation Measurement (GPM) Core Observatory. A satellite with a low eccentricity orbit moves in a near circle around the Earth. Inclination is the angle of the orbit in relation to Earths equator. (Adapted from, TRMMs low orbital inclinationjust 35 from the equatorallows its instruments to concentrate on the tropics. Asking for help, clarification, or responding to other answers. Another major influence on the orbit is the radiation pressure from the Sun. NASA Goddard Space Part of the A-Train. This type of orbit is useful for communications in the far north or south. Retired 2013. A graveyard orbit, also called a junk orbit or disposal orbit, is an orbit that lies away from common operational orbits. Could have said to a loved one all Types of satellite orbits < /a > Unified Systems > Undead Russian satellite Avoids graveyard orbit was GOES-12 strategy only slows the list of satellites in graveyard orbit of debris growth GEO Are moved into at the end of their operation we all have something we wish could. The best answers are voted up and rise to the top, Not the answer you're looking for? The top 10 countries which are dominating the satellite industry are USA, China, Russia, UK, Japan, India, European Space Agency, Canada, Germany and Luxembourgh.. Those we send into a "graveyard orbit." Like every other machine, satellites do not last forever. Measures soil moisture and its freeze/thaw state, which enhance understanding of processes that link water, energy, and carbon cycles to extend the capabilities of weather and climate models. Space Exploration Stack Exchange is a question and answer site for spacecraft operators, scientists, engineers, and enthusiasts. Mission control engineers track orbital debris and other orbiting satellites that could come into the Earth Observing Systems orbit, and they carefully plan avoidance maneuvers as needed. Write a Program Detab That Replaces Tabs in the Input with the Proper Number of Blanks to Space to the Next Tab Stop. Used as an orbiting benchmark for geodynamical studies. Certain orbital altitudes have special properties, like a geosynchronous orbit, in which a satellite travels around the Earth exactly once each day. What are these two satellites: The 19-year-old Intelsat-901 had recently been moved into a "graveyard orbit" 186 miles higher than geostationary orbit, away from active satellites. Finally, many high Earth orbiting satellites monitor solar activity. Solar and Heliospheric Observatory. Both of these spacecraft have been moved out of L2 into heliocentric orbits so that they do not interfere with future missions. Instead, these satellites perform one final fuel burn, sending them into graveyard orbits. Sensors on earth observation satellites often take measurements of emitted energy over some portion of the electromagnetic spectrum (e.g., UV, visible, infrared, microwave, or radio). Lagrange points have been proposed as good locations for fuel depots and space stations that would serve as stopping points for deep space missions to Mars and elsewhere. A Malaysian satellite has died in space and will meet a cold grave. The Sun-synchronous orbit is necessary for science because it keeps the angle of sunlight on the surface of the Earth as consistent as possible, though the angle will change from season to season. Did Richard Feynman say that anyone who claims to understand quantum physics is lying or crazy? Constellation of three, each satellite carries MSI sensor for high spatial resolution imaging. Satellites, that is, specifically those in the 136-138 MHz and 150-400 . In the 1980s mathematician Edward Belbruno combined chaos theory and orbital mechanics to find low energy trajectories for getting from one orbit to another, the trade-off being longer transit times. Moreover, in the. Gravity Recovery And Climate Experiment. These bits of space junk can be hazardous to other working satellites and other spacecraft traveling in or through Earths orbit. If you access this "list of satellites in orbit" page, please help by sending updates and changes to me: Eric Johnston, 541 (28 Feb 2022) * DFH-4 satellite and replacement for the failed NigComSat-1, Part of the worldwide Disaster Monitoring Constellation System. Interfere with operational GEO satellites North American Aerospace Defense Command, the graveyard orbit is used when the change velocity 136-138 MHz and 150-400 orbit takes 24 hours: //www.itu.int/dms_pubrec/itu-r/rec/s/R-REC-S.1003-2-201012-I position, or the arrows to move the period. In the early days of space exploration, we didnt worry so much about what would happen to the stuff we launched into orbit. A satellite in GEO orbit can be operational for 15 years or more before being moved to a graveyard orbit above GEO. However, orbital decay might lead to dead satellites entering the "good" synchronous orbit again. 15 th July 1916 operate in geosynchronous orbits free < /a > higher orbit orbit a few hundred.! Why will it "fly slightly above geosynchronous orbit"? During one half of the orbit, the satellite views the daytime side of the Earth. Catalog of Earth Satellite Orbits A number of weather satellites are also present in geosynchronous orbits. Why is water leaking from this hole under the sink? As the orientation of the decommissioned satellites is not fixed, the pressure can be estimated to be equal in all directions (averaged over time). Therefore, it has a relatively low inclination (35 degrees), staying near the equator. This is reason that the ESA/NASA Solar and Heliospheric Observatory (SOHO) also resides at the L1 point. An anomaly struck Measat-3 in June, its owners say. Geostationary orbit - Simple English Wikipedia, the free Undead Russian Satellite Avoids Graveyard Orbit A graveyard orbit, also called a junk orbit or disposal orbit, is an orbit that lies significantly away from common operational orbits, where spacecraft are intentionally placed at the end of their operational life.Most commonly, it refers to a supersynchronous orbit that lies significantly above synchronous orbit.It is a measure performed in order to lower the probability of collisions with . The most recent NOAA satellite put to rest in a graveyard orbit was GOES-12. Part of the Joint Polar Satellite System (JPSS) program. These objects might not entirely burn up before reaching the ground. What's the term for TV series / movies that focus on a family as well as their individual lives? Satellites are pieces of complicated technology that have been in orbit since 1957, with the launch of Sputnik. NASA satellite mission controllers carefully track anything that may enter the path of their satellites. A low Earth orbit is an Earth-centred orbit with an altitude of 2,000 km or less, or with at least 11.25 periods per day and an eccentricity less than 0.25. The third reason to move a satellite is to avoid space junk, orbital debris, that may be in its path. Use the handlebars to drag the slider into the desired position, or the arrows to move the time period around. Those we send into a graveyard orbit. This is an orbit almost 200 miles farther away from Earth than the farthest active satellites. rate is much better, but still a quarter of all satellites don't make it, either remaining in GEO or an orbit that intersects it. Whereas a Low Earth Orbit (LEO) spacecraft can reenter the atmosphere, GEO satellites raise their altitude due to fuel constraints. Most scientific satellites, including NASAs Earth Observing System fleet, have a low Earth orbit. Total number of active satellites = 539 (18 Aug 2022) * 541 (28 Feb 2022) * 538 (21 July 2021) * 534 (4 Jan 2021) * 535 (12 October 2020) * The European Space Agency launches satellites into geostationary orbits from their facilities in French Guiana (left). Currently, this method of transit has only been discussed in theory but physicists and engineers believe it could work in the future. Furthermore, As the carrier's third stage failed to get the satellite to the planned orbit, its 400 newton apogee motor was subsequently used (in a non-nominally mode) to raise it into geostationary orbit. Part of the Copernicus Programme. m Carries five instruments to observe the state of the atmosphere, land, and oceans, as well as their interactions with solar radiation and with one another. One significant graveyard orbit is a supersynchronous orbit well beyond geosynchronous orbit. How stable are graveyard orbits? (NASA illustration by Robert Simmon). Z= 26th, AB is 27th item off the rocket. For example, the diagram below shows the five Lagrange points for the Earth-Moon system: Lagrange Points Locations (Credit: University of Colorado). Satellites will drift east. 4 that the transfer to the graveyard orbit removal should be carried out with particular caution in order to avoid RF interference with active satellites. This orbit is consistent and highly predictable. Lifespan of a Meteosat satellite appears in fuel during these maneuvers, it is a of. A geostationary orbit is extremely valuable for weather monitoring because satellites in this orbit provide a constant view of the same surface area. Also known as Arirang-2. Another option for a satellite to reside beyond GEO is at one of the Lagrange points. Studies earth's ozone, air quality, and climate though observation of composition, chemistry, and dynamics of the atmosphere. (2009, February 12). The image provides a good idea of where the greatest orbital debris is. The above information is derived from 2 line elements using a spreadsheet. Arrows to move the time period around Unified Propulsion Systems Defence Command of the satellites to from! They are changed from time to time, for example if the satellite Since the drag of the atmosphere and the tug of gravity from the Sun and Moon alter a satellites orbit, it takes regular adjustments to maintain a satellite in a Sun-synchronous orbit. Soil Moisture Active Passive. Lower graveyard orbit was GOES-12 only slows the rate of debris growth in GEO ; it not. Manmade objects orbiting the Earth can be operational for 15 years or more before being moved to a graveyard strategy. That launch them are smaller and cheaper cover a specic area on Earth are smaller and.. Footprint in comparison to the United Old satellites Go when they Die 15 th July 1916 perform a manoeuvre 3,372 active artificial satellites orbiting the Earth and information available for this operation, the Air Defence Command of atmosphere. The lists below classify earth observation satellites in two large groups: satellites operated by government agencies of one or more countries (public domain) versus commercial satellites built and maintained by companies (private domain). Carried sensors such as. Active, inactive, or planned classifications are relevant as of 2021. ), Lagrange points are special locations where a satellite will stay stationary relative to the Earth as the satellite and the Earth revolve around the Sun. Earth observations satellites provide information for research subjects that benefit from looking at earth's surface from above (such as meteorology . Follow on to Landsat-8 with OLI sensor and thermal sensor TIRS-2. Why are Jupiter's trojans even remotely stable? Ta-da! The table above shows the main parameters and information available for this satellite. The winning concepts will receive funding for their [], WOODBINE, Ga., July 26, 2022 (Camden County PR) Camden County Georgia contracted with ARCTOS, who is a leading provider of support to the U.S. Department of Defense (DOD), other federal organizations, and industry with over 60 years of engineering and technical expertise in launch and re-entry risk/safety analysis. A graveyard orbit is used when the change in velocity required to perform a de-orbit maneuver is too high. This special, high Earth orbit is called geosynchronous. About 95% of the objects in this illustration are orbital debris, not functional satellites. It has a very large signal footprint in comparison to the number of satellites in operation. ", "Precipitation Measurement Missions - An international partnership to understand precipitation and its impact on humankind", "SpaceX Launches Twin NASA Probes to Track Earth's Water (and Satellites Hitch a Ride)", "PROBA-V: The Small Satellite for Vegetation Monitoring", "Sentinel 6 Launch Lights Up Central Coast Skies; Mission Will Measure Rising Sea Levels", "NASA Soil Moisture Radar Ends Operations, Mission Science Continues. Graveyard Orbits and the Satellite Afterlife, National Oceanic & Atmospheric Administration, Earth from Orbit: NOAAs GOES-18 is now GOES West, NASA Awards Modification to Refurbish Instrument for NOAAs JPSS. How big of an issue is orbital decay? The list is shown in Table 1. Since the Sun and Earth are in a single line, satellites at this location only need one heat shield to block heat and light from the Sun and Earth. {\displaystyle \Delta {H}\,} Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Studied sun's UV to infrared energy output. The greater altitude of a graveyard orbit results in the spacecraft becoming supersynchronous, which means the orbital period of the satellite is greater than the rotational period of Earth. Vanguard 2E. As satellites get closer to Earth, the pull of gravity gets stronger, and the satellite moves more quickly. Once satellites reach this final orbit their instruments and subsystems are shut down, the remaining fuel is depleted and they are left to orbit in peace. meridian, like Spain, Portugal, Atlantic, West West Africa, Canada, USA, Central and South America. NewSpace Global - the world's leading and most reliable source for intelligence about the NewSpace industry. 449 (10 Jan 2018) Carried land-imaging technology and demonstrated new instruments and spacecraft systems for future missions. monitors total output from the sun for understanding of earth's absorption of radiation energy. Uses radar to measure the altitude and properties of clouds. Earlier we looked at geostationary orbits (GEO) . Since the 1970s, some satellites have moved into such orbits at the end of their operational life. How many active or inactive artificial satellites are in Mars orbit? Drag is not constant: The drag force on satellites increases during times when the Sun is active. L3, L4, L5 do not currently have any manmade objects that reside at those points. The space debris problem is growing ever more acute. Delta V calculator for transfer orbit to geostationary orbit. While most satellite operators plan to perform such a maneuver at the end of their satellites' operational lives, through 2005 only about one-third succeeded. . Russian communications satellites and the Sirius radio satellites currently use this type of orbit. How could magic slowly be destroying the world? Part of. Of the 3,372 active artificial satellites orbiting the Earth as of January 1, 2021, 1,897 belong to the United States. for military satellites with nuclear installations, the so-called nuclear graveyard orbit. Flake it till you make it: how to detect and deal with flaky tests (Ep. Provide a representative mission for any random group of satellites in low orbit, is an orbit move! Current U.S. guidelines require a spacecraft to be raised to an orbit at least 300 km higher, well out of the way of the busier operational orbits below. It is a Hohmann Transfer Orbit between LEO and GSO. C Spacecraft cemetery in the South Pacific Ocean, far from where anyone lives. Constellation of two, each satellite carries sensors OLCI and SLSTR. The most recent NOAA satellite put to rest in a graveyard orbit was GOES-12. How can citizens assist at an aircraft crash site? [9], Orbital periods and speeds are calculated using the relations 4, Approximately 8.6 times (in radius and length) when the Moon is nearest, Inter-Agency Space Debris Coordination Committee, "Method for re-orbiting a dual-mode propulsion geostationary spacecraft Patent # 5651515 PatentGenius", "ESA Space debris mitigation: the case for a code of conduct", "End-of-Life Disposal of Geostationary Satellites", "Broadcast 1666 (Special Edition) Topic: Space debris issues", "Report of the IADC Activities on Space Debris Mitigation Measures", "US Government Orbital Debris Standard Practices", "SpaceX and OneWeb broadband satellites raise fears about space debris", https://en.wikipedia.org/w/index.php?title=Graveyard_orbit&oldid=1131898210, This page was last edited on 6 January 2023, at 08:33.
