Description:

Tables - Launches and Orbits Zarya.info:The Kettering GroupProviding Space Information Since 1999Zarya.info is a hobbyist website managed from the South Tyneside area of the UK. Here you will find things that interest me..... current space events, the Soviet/Russian space programme, satellite tracking.Space HistoryZarya.info covers areas of space history, mainly Soviet and Chinese but some other nations as well. There are detailed histories of selected events and programmes as well as analyses of orbits and trends. Links in the right hand menu will take you there.See Zarya's launch lists for a range of years. They show satellite descriptions, launch records, detailed orbits and histories of orbital manoeuvres. Information is derived from data provided by SpaceTrack and from independent tracking undertaken by amateur satellite observers.The lists run from 2008 to the present. Some earlier years starting in 1957 are also available.Special OrbitsThere are also detailed lists of satellites in specialised orbits. In Geosynchronous orbit satellites are mainly communications satellites and Earth observation vehicles watching a whole hemisphere at a time. Sun-synchronous orbits follow a track across the Earth's surface at the same time each day. They are principally imaging satellites taking advantage of the constant lighting conditions from day to day.What's Coming Down?Most objects that find their way into orbit eventually find their way back into the Earth's atmosphere, the event is often referred to as "Decay".Natural decay of an orbit driven by air drag brings it closer to the upper atmosphere, resulting in greater air drag. Eventually, the drag will prove too much and it will enter the atmosphere. Re-entries can produce spectacular fireballs. Larger objects coming back into the Earth's atmosphere do not always burn away completely so there is a possibility of fragments hitting the ground.In some cases, usually where the satellite is in a highly eccentric orbit, gravitational influences can force perigee deep into the Earth's atmosphere where air drag does the rest and decay occurs.Sometimes re-entries are brought about deliberately by retro-fire slowing the vehicle down. Occasionally the objective is to ensure that any surviving fragments land in remote areas of the Ocean but sometimes the objective is to make a landing.Tables show recent re-entries as well as predictions of forthcoming events. Information comes from SpaceTrack and is updated as new data comes in.2016 - A Notable AnniversaryIn the 1960s, a small group of teachers and schoolboys were using basic radio equipment to eavesdrop on Soviet/Russian satellites. They came to prominence in 1966 when they deduced that the Soviet Union had made its first space launch from a new cosmodrome. 2016 marked the 50th anniversary of the event that catapulted the group into the international limelight.Talks and LecturesIf some of the material on the zarya.info website interests you enough, and you represent a local astronomy society, club or any other group in the UK, or even in Europe if a low-cost flight is available, then a talk or lecture can probably be arranged.Use the 'mail' icon towards the upper right of the page if you are interested.Talks & LecturesSchools, clubs, societies - space exploration and historyOn OrbitCurrent and historical launch lists, re-entry predictions and diaries, lists of satellites in specialised orbits.The Kettering GroupPeople, reminiscences and tracking equipmentRussian RealmsAspects of the Soviet and Russian programmesChinese MealPiloted Programme and Other MissionsKorean CollectionMachinations of the Democratic Peoples RepublicIran In OrbitSlow steps into space from an emerging nationAmerican PieSnippets from across the PondISSMission calendar for the early yearsSatellite TrackingTechniques, analysis and results of tracking activitiesRadio FrequenciesFrequency lists, transmission details, BEWARE - last updated 2014Google Earth 'Tours'Virtual tours of space placesTyneside SatellitesSatellite visibility predictions for the Tyneside areaSouth Tyneside Weatherzarya.info's weather station for South Tyneside
