Draggendrop Veteran Posted June 15, 2015 Author Veteran Share Posted June 15, 2015 Space debris....We'll have one less piece at approximately 12:00 EDT on Tuesday, June 15. The TRMM, Tropical Rainfall Measuring Mission, satellite, co-sponsored by NASA and Japan's JAXA, will re-enter and "mostly" burn up....there will be a few spare parts thrown around...area...unknown.........yard sale availability...to be determined........ About 12 pieces of space debris from the nearly 3-ton satellite are expected to survive the plunge through Earth's atmosphere and reach the surface. The chance that one of these pieces would strike someone is approximately 1 in 4,200, which is a relatively low chance, according to NASA's Orbital Debris Program Office. As its name suggests, the TRMM satellite's orbit brings it over the tropics between 35 degrees North latitude and 35 degrees South latitude. The earth-watching satellite launched from Tanegashima, Japan on Nov. 27, 1997 on a planned three-year mission. TRMM ultimately lasted about 17 years before it was shut down on April 15 of this year. According to the NASA Orbital Debris Program Office, the estimated human injury risk (updated in 2015) is roughly 1 in 4,200. One in 4,200 means that if the same re-entry were to occur repeatedly 4,200 times, the expectation is that that only one person on Earth would be harmed. "Since the beginning of the space age in the 1950s, there has been no confirmed report of an injury resulting from re-entering space objects," NASA officials wrote in a statement. http://www.space.com/29664-nasa-satellite-falling-out-of-space.html /s.................Meanwhile in other news, several countries have announced Tuesday as "National Hardhat Day"................

BTW What sort of quality was the data over all those years? As you realize, statistical analysis is a "fuzzy entity unto itself", any data can be manipulated to achieve the outcome desired for spin control. It can also be used for great discovery. The quote is from NASA itself and is portrayed as odds that may be different to others perception of usage....read the fine print. In this cause, they have stated that they could throw this satellite at the atmosphere 4,000 times and 1 person could be hit. Think of it another way....7 billion people on the planet, have everyone allotted 10 square feet while standing...combine the 7 billion area's and you will have an area less than 100 miles x 40 miles ((160 km x 60 km)....the rest of the planet is free........gives a context. The next item is reporting....does everyone know space junk....or do we require people hit by a panel to show up with the panel stuck in your head.....NASA has standards for it's statistical reporting of an event......would take a search to find out...but when it comes to this dry stuff.....give it a "google", but I suggest you would have more fun in other ventures....good question though arachnoid....you're putting the boots to us lately.. /s Airport movie...."I'm not Shirley...she is....(points to blow up doll in pilots seat)............

Draggendrop Veteran Posted June 16, 2015 Author Veteran Share Posted June 16, 2015 Carrying on with our space debris concerns....at what point do we have so many satellites in LEO that it constitutes a hazard to get through that orbital sphere slice. atellites are tracked by United States Space Surveillance Network (SSN), which has been tracking every object in orbit over 10 cm (3.937 inches) in diameter since it was founded in 1957. There are approximately 3,000 satellites operating in Earth orbit, according to the US National Aeronautics and Space Administration (NASA), out of roughly 8,000 man-made objects in total. In its entire history, the SSN has tracked more than 24,500 space objects orbiting Earth. The majority of these have fallen into unstable orbits and incinerated during reentry. The SSN also keeps track which piece of space junk belongs to which country. http://www.wisegeek.com/how-many-satellites-are-orbiting-the-earth.htm WE have many more constellations of devices going up still....such as....

Draggendrop Veteran Posted June 17, 2015 Author Veteran Share Posted June 17, 2015 The ISS abounds with experiments requiring micro gravity. Now we may see physicists suiting up for a ride to the ISS, Bigelow units or the moon for a few quantum experiments. Gravity, still with a few unknowns, has it's force felt mainly at large scale. This force has been overlooked at very small scale experiments with normally good results. The problem being, once an experimental quantum size gets bigger (still very small), gravity kicks in and ruins results. The superposition principle can be thought of as two states in one occurrence...is it a particle..is it a wave. For macro analyses,a lot of wave functions are evident. As we get to the quantum state....particles become more evident and superposition as well. Think of an electron cloud in orbit...meaning we have a general idea of position....but the further we test for accuracy....we define one variable and loose the other. On the macro scale...think of a ball player...a pitcher throwing a fast ball...looks fluid, like a wave equation...dilate time..and we get jumpy particle movement gaining quanta for the next energy level...rough example but we get the idea. Time dilation, is what makes time appear different to different observers...like a week in a worm hole being months on a planet... /s...........Here we go " The Big Bang" cast in space suits.....definitely going to be entertaining........ http://www.newscientist.com/article/dn27735-earths-gravity-may-force-us-to-do-quantum-experiments-in-space.html Link to comment https://www.neowin.net/forum/topic/1258256-international-space-station-updates/page/8/#findComment-596891168 Share on other sites More sharing options...

Draggendrop Veteran Posted June 18, 2015 Author Veteran Share Posted June 18, 2015 While browsing space and physics sites, I came across a "look back at" article which featured the Russian MIR space station. I thought it would make a good post to "show and tell" about this very important station......it was what made the ISS possible. 1) 20 February 1986 till 23 March 2001 2) 5519 days in orbit, 4592 occupied 3) 86,331 orbits, speed was 7,700 m/s (27,700 kph) 4) 129,700 kg, L x W x H was 19 m, 31 m, 27.5 m, mass was 129,700 kg 5) altitude was 350 km to 370 km Originally started by the USSR, the station became a multinational training lab, spurred the Shuttle-MIR program, and was such a success that a prior MIR-2 project was scraped in favour of a multinational space station called ISS, a renamed US project called Freedom. https://en.wikipedia.org/?title=Mir http://phys.org/news/2015-06-mir-space-station.html MIR during 1996...

Draggendrop Veteran Posted June 19, 2015 Author Veteran Share Posted June 19, 2015 One of the biggest problems with existing satellites, is maintaining orbital position for geosynchronous or maintaining correct orbital altitude and velocity for moving satellites. This requires fuel for thrusters...the more you use the thrusters...the less fuel you have...the sat's lifetime is reduced. NASA has been testing robotic refueling techniques, a few times on the ISS with mock systems and extensive test on earth by remote control. Commercial applications have been well received but real market needs to be evaluated as well as insurance implications... More than 1,100 satellites are orbiting the Earth right now transmitting TV shows and phone calls, collecting rainforest data and spying on missile bases around the planet. Most are expensive, costing tens or hundreds of millions of dollars to build, launch and operate. Now NASA wants to build a satellite service station that can gas up and repair aging birds, giving them a few years more life before they fall into the Earth's atmosphere and http://www.space.com/29698-orbiting-rest-stops-repair-satellites.html NASA astronauts have been practicing during two Robotic Refueling Missions on the International Space Station in 2011 and 2014, while engineers on the ground at Goddard have been developing new kinds of fuel nozzles, wire-cutters, drills and other robotic tools. They also built a shiny, gold-foil-covered, 20-foot tall mockup of the Landsat-7 satellite in order to practice docking maneuvers necessary for fueling up in space. http://www.space.com/29698-orbiting-rest-stops-repair-satellites.html Simulated refueler satellite......

This requires fuel for thrusters...the more you use the thrusters...the less fuel you have...the sat's lifetime is reduced. > That's less of a problem now that satellites are being equipped with solar-electric propulsion (SEP), usually in the form of Hall Effect thrusters which use either xenon, argon or krypton as a reaction mass. This takes the propellant mass down from 1-3 tonnes to as little as 10-50 kilograms. Some Hall thrusters aren't much larger than a computer case fan. There are even SEP units which can fit in a tiny cubesat.
