The population of natural Earth satellites
Mikael Granvik, Jeremie Vaubaillonc, Robert Jedickea Abstract We have for the first time calculated the population characteristics of the Earth’s irregular natural satellites (NES) that are temporarily captured from the near-Earth-object (NEO) population. The steady-state NES size-frequency and residence-time distributions were determined under the dynamical influence of all the massive bodies in the solar system […]
ROSAT satellite- latest news
October 23, 2011
(update) From bbc/news: “…Just as for Nasa’s UARS satellite, which plunged into the atmosphere in September, there was high uncertainty about the final moments of Rosat. But if the timings are correct, any wreckage would probably have dived into the Indian Ocean – although no eyewitness reports have yet come in. If anything did manage […]
What Are the Odds You’ll Get Struck by the Falling ROSAT Satellite?
October 19, 2011
This exclusive image was made by Ralf Vandebergh, who said: “”It is false-color to increase certain visible contrasts. A very special detail visible is the shadow of the body (the telescope) on the solar panels! You can see the angle with the sun and the observer (me) as ROSAT passed not overhead but [at] 51.4 […]
App tracks ROSAT satellite’s crash to Earth
October 13, 2011
ROSAT, a defunct X-ray telescope, is crashing to Earth sooner than expected owing to enhanced solar activity, says Johann-Dietrich Wörner, executive director of DLR, the German lab in charge of the mission. It was thought that the 2.4 tonne spacecraft would deorbit in late October or early November, but Wörner says the re-entry date is […]
Remains of satellite may never be found, NASA says
September 26, 2011
A six-ton NASA science satellite crashed to Earth on Saturday, leaving a mystery about where a ton of space debris may have landed. The U.S. space agency said it believes the debris ended up in the Pacific Ocean, but the precise time of the bus-sized satellite’s re-entry and the location of its debris field have […]
UARS Will Hit the South Pacific Today
September 23, 2011
Orbital scientists say that the falling Upper Atmosphere Research Satellite (UARS) will not impact the ground over US territory. According to the latest predictions, it will splash in the South Pacific Ocean, a little to the north of New Guinea. Over the past few days, experts have been hard at work in analyzing the trajectory […]
Second big satellite set to resist re-entry burn-up
September 23, 2011
Even if NASA’s 6-tonne UARS satellite does not cause any injury or damage when it re-enters the Earth’s atmosphere today, there is more space junk headed our way next month. A defunct German space telescope called ROSAT is set to hit the planet at the end of October – and it even is more likely […]
Space junk rising exponentially
September 2, 2011
The amount of junk in space is rising exponentially, with continuous collisions between abandoned equipment, spent rockets and other debris creating ever growing clouds of dangerous fragments, an influential report warned on Thursday. The report, commissioned by Nasa, says the quantity of hazardous material circling the Earth has reached a “tipping point” and poses a […]
