Meteorite Crashes In Russia, Panic Spreads (Updating) - 5 views

    Latest update: the European Space Agency says their experts "confirm there is no link between the meteor incidents in Russia and asteroid 2012DA14 flyby tonight". How did they find this? As they did not see this one coming, how could they come to that conclusion that early!

    As you can see from the videos of this meteorite it is coming in from an east to south-east direction (i.e. the direction of the sunrise, more or less). 2012DA14 is coming from due south as you can see here: http://www.wired.com/wiredscience/2013/02/how-to-watch-asteroid-2012-da14/ So the two objects seem to be coming from different directions - at least that would be my explanation.
  • Joris _ on 15 Feb 13
     
    My point is, that if you want to come to such a conclusion (that it is not rubble) you need to be able to construct back the orbits of both objects. 2012DA14 has been observed for one year only, but it is well enough. When the meteor has been observed for the first time, such that we knew its orbit? has it been observed before? if yes, why the impact has not been predicted?
  • johannessimon81 on 15 Feb 13
     
    If you can show that they come from different directions you know that they are not associated, even if you don't reconstruct their orbits.
  • Joris _ on 15 Feb 13
     
    I don't think so. If both objects were part of the same, they would be on different but intersecting orbits anyway, hence different directions. Anyway, I am not knowledgeable in atmospheric entry ... But, with so few information about the object, I am surprised they are 100% certain it is not related to DA14. I think science requires more cautions ... With only the direction they are 100% sure, while the probability of such event is itself extremely small, I am amazed... They can't even predict with 100% certainty where a space debris will fall... plus, nobody consider the object being part of a bigger one that broke up during early entry (which has not been observed) ... so many uncertainties and possible hypothesis... and i am not the only one :) http://www.infowars.com/russian-meteor-linked-to-da14-asteroid/

    was not that evident to me also but apparently with the right understanding it was quite clear; was amazed also how quickly NASA has published the likely trajectory of the russian object - have a look at it: quite evident that these are not coming from the same body
  • Joris _ on 17 Feb 13
     
    yes, now i get my 100% certainty with the reconstructed orbits nothing else (http://wiki.nasa.gov/cm/blog/Watch%20the%20Skies/posts/post_1361037562855.html) ... I still think that esa anouncemement was highly premature but with a high probability of being right...

    ESA's article on the consequences for ISS: http://www.esa.int/esaCP/SEM6GJUTTRG_index_0.html What is not clear is if the rocket that failed is the same variant as used in manned missions. [Edit] According to this article: http://www.interfax.com/newsinf.asp?pg=3&id=268437 "The first and second stages of the Soyuz-FG space rocket used for manned launches differ from those of the Soyuz-U, but the third stage [the one that failed - MR] is identical in both rockets". Thus the stay of astronauts currently at ISS may prolong a little bit.

    " This isn't Camilla's first adventure. The chicken has also flown on a NASA T-38 training jet, traveled onboard a helium balloon to the stratosphere over Louisiana, visited the Yuri Gagarin Cosmonaut Training Center in Star City, Russia, and visited hundreds of elementary students in classrooms around the country. " Pretty impressive Camilla ! Congratulations :)

    An international team of researchers, led by physicists from Lund University, have confirmed the existence of what is considered a new element with atomic number 115. The experiment was conducted at the GSI research facility in Germany. The results confirm earlier measurements performed by research groups in Russia.

  • "The corporation promised to clean up the space in ten years by collecting about 600 defunct satellites on the same geosynchronous orbit and sinking them into the ocean subsequently,"
  • He said the cleaning satellite would work on nuclear power and be capable to work up to 15 years.
  • Energia said that the company would complete the cleaning satellite work-out and assembly by 2020 and test the device no later than in 2023.

    Hehe... as far as I know the Russians, they won't miss a chance to "clean up" a few enemy satellites too...

  • The termination of NASA's space shuttle program marks the end of a nearly 54-year rivalry between the USSR and the United States to achieve superiority in space exploration.
  • Sources confirmed that in commemoration of the capitalist defeat, extra bread and corn rations had been approved in all major cities, and factory workers were given time off their nine-hour work shifts to join in the festivities.
