  1. Hi Ray, My old/original avatar is not being displayed and I am unable to reload it - all I get is "Working....." - cept' it ain't !! Also, I am not authorised to PM you !! Cheers, gyro.
  2. I don't think NASA expected this amount of wear and tear just yet, this doesn't bode well fora lengthy mission scrambling around the foot hills of Mt Sharp.
  3. Ray, the wheels fold out to normal position, when suspended from the sky crane, prior to touch down.
  4. Some of that damage looks more like brittle breakage rather than abrasive wear. - maybe the landing impact was heavier than calculated and we are now seeing metal fatigue. We will have to wait for the next JPL Ustream media report explanation - I'll post it.
  5. I think its a case of "Houston - we have a problem" http://www.nasa.gov/jpl/msl/traverse-map-20140219/#.UwpJkfl_uSo
  6. Latest JPL media briefing on Mars activity. http://www.ustream.tv/recorded/43015386
  7. Mars news briefing.

    Is it possible to modify the ISS as a Mars vehicle. Add propulsion modukes, Mars lander module and a improved dedicated safe area from radiation etc.
  8. On 20 January 2014, ESA?s comet-chasing Rosetta spacecraft is set to wake up from 957 days in deep-space hibernation to rendezvous with Comet 67P/Churyumov-Gerasimenko where it will study the nucleus of the comet and its environment for nearly two years, and land a probe on its surface.
  9. If we look back fifty odd years Sputnik 1 managed just 8km/s
  10. Yesterdays media tele-cast. If it doesn't start click the top right thumbnail . takes a few seconds to stream. http://www.ustream.tv/nasajpl
  11. ISRO successfully launch Mars propbe. Seems to me that if all Countries and Space agencies could get together and work as one there would be a huge cost saving. http://www.isro.org/
  12. Well done India.

    Well done China - but again a pity their resources not part of a international Lunar project.
  13. The good news for UK members is that the weather is set fair and clear for dawn tomorrow (Sat 30th) - here's hoping there is something left to observe.
  14. Ray, EH was a friend of Newton - he used his Gravity theory and the observed positions, as a function of time, to predict the orbit. Good luck with the maths mate :bah:
  15. I'm confused ..... SOHO is in a halo orbit at L1, so how do we convert a position/track of ISON from a SoHO image to the co-ords from Earth to answer Radars's question.
  16. Hopefully ISON isn't the comet of the century - there is still a long time to go :eartoear:
  17. Comet ISON Nov. 10th, Mag. 7

    My latest info' is it peaks at mag -4.4 on the 29th.
  18. Comet ISON Nov. 10th, Mag. 7

    Being near Leeds I'm hoping for a sighting just before Sunrise, around the 29th Nov, low in the SE.
  19. See APOD for Nov 3rd ...... http://apod.nasa.gov/apod/ap131103.html
  20. Interesting little vid' tries to explain this enigma. http://ed.ted.com/lessons/the-moon-illusion-andrew-vanden-heuvel
  21. Without the input from wingeing Pom and timelder this Board would be dead. I held off posting about Higgs Nobel prize hoping someone else would mention it - no-one did !! You see I have an issue with this supposed discovery - I follow CERN but can't remember they have announced the definitive evidence of the 'Higg's Boson' - only that an indication it has been observed. Discuss ............
  22. Ah - understood. If you are ever looking for podcast material for you ducumemtary slot then look no further than your fellow antipodean - Steve Nerlich of Cheap Astronomy.One of the best Astro' educators on the net ..... http://www.cheapastro.com/#/cheap-podcasts/
  23. This vid' may be of interest to you Astro' photography enthusiasts ........
  24. ISON - APOD yesterday ..... http://asterisk.apod.com/library/APOD/APOD%20mirror/ap131007.html
