A thread concerning both aviation and space flight coupled together with the branch of science which deals with celestial objects, space, and the physical universe as a whole. The Chinese space station Tiangong-1 is set to fall to Earth over this weekend. The latest from the European Space Agency (ESA) predicts 1615 hrs GMT on Sunday 1st April 2018 plus or minus nine hours. This tracker is continuously updated to show the current position and height as the orbit decays. When Skylab fell to Earth in 1979 a $400 littering ticket was issued by a park service official in Western Australia; apparently it still hasn’t been paid and has been written off. Useful Sites Heavens-Above is a website developed and maintained by Chris Peat as Heavens-Above GmbH. The web site is dedicated to helping people observe and track satellites orbiting the Earth without the need for optical equipment such as binoculars or telescopes. It provides detailed star charts showing the trajectory of the satellites against the background of the stars as seen during a pass. Special attention is paid to the ISS, Iridium flares and other satellites. Space shuttle missions were tracked until the program was retired in July 2011. The website also offers information on currently visible comets, asteroids, planet details, and other miscellaneous information. N2YO provides real time tracking and pass predictions with orbital paths and footprints overlaid on Google Maps.It features an alerting system that automatically notifies users via SMS and/or email before International Space Station crosses the local sky. The N2YO.com system powers ESA's, Space.com's and many other's satellite tracking web pages. NASA Lunar Eclipse Explorer computes the local circumstances for every lunar eclipse for any century from 2000 BC to 3000 AD. Forget about city etc, just enter your latitude and longitude as a decimal. NASA Solar Eclipse Explorer computes the local circumstances for every solar eclipse for any century from 1500 BC to 3000 AD. Again, forget about city etc, just enter your latitude and longitude as a decimal. International Space Station Transit Finder calculates when the ISS transits across the face of the sun and moon from a position near you. Don’t forget your solar filters if you’re looking at the sun. Telescope.org is where you can request The Open University’s automated telescope on Mount Teide, Tenerife to take a photograph for you. Airliners.net is an aviation website that includes an extensive photo database of aircraft and airports, as well as a forum catering to civil and military aviation together with spaceflights. If you have any questions, please ask and I’ll do my best to answer them.
