Martin Harris - Moderator Posted September 22, 2011 Share Posted September 22, 2011 ...if the NASA satellite lands on my head. I do wonder whether the operator has read Articles 74 and 98 of the ANO? Do be careful of the sharp edges (I loved that bit!!!) if you find it in your garden or at your flying field and I suspect it may be rather hot for an hour or two.Edited By Martin Harris on 22/09/2011 10:33:00 Quote Link to comment Share on other sites More sharing options...
Biggles' Elder Brother - Moderator Posted September 22, 2011 Share Posted September 22, 2011 I've just emailed our Research Institute Safety Officer asking him to carry out a risk assessment and modify any of existing RA's accordingly! Like most Satety Officers he's a little short on sense of humour! BEB Quote Link to comment Share on other sites More sharing options...

Allan Bowker Posted September 22, 2011 Share Posted September 22, 2011 Speaking of TV Chris, is our area fully switched over now Chris?

Martin Harris - Moderator Posted September 22, 2011 Author Share Posted September 22, 2011 It does seem a little odd that we have to fit failsafes and are legally bound to be reasonably satisfied that our flights can be completed safely with models weighing more than 7kg when an organisation like NASA seems to be able to launch something which they freely admit could land uncontrolled virtually anywhere on Earth. I know they are from the USA so I wonder what the AMA would have to say? Surely it shouldn't be too difficult to control where it lands? If not controlled, why not exploded over an ocean or USA desert? I'm generally supportive of space research and exploration but I'd guess the risks of losing the satellite to a premature detonation outweigh the projected costs of compensation for anyone unlucky enough to be landed on?

Biggles' Elder Brother - Moderator Posted September 22, 2011 Share Posted September 22, 2011 I think the technical problems are pretty challenging Martin. Once it enters the atmosphere its going to start to tumble - so its trajectory is anyones guess. As for blowing it up - with what? Its doing 5 miles a second! We've nothing that could hit it! I suppose you could say why didn't they put a "self-destruct" charge on board, but lets be honest every gram of payload is precious on these things and hindsight is a wonderful thing! Having said all that, if I have the misfortunate to have model go in out of control (finger's crossed, touch wood) I shall at least count myself in good company!

i12fly Posted September 22, 2011 Share Posted September 22, 2011 Typical American authorities, they do something risky and then let the rest of the world deal with the poo. Look at the economy, last time obviously irresponsible sub prime mortgages, and now they bicker and refuse to act sensibly on their outrageous debt problem which now appears too big to resolve.

Lazygit Posted September 22, 2011 Share Posted September 22, 2011 It seems it remains the property of NASA even if it crashes in your garden. I am al least going to charge them for unauthorised parking. I could clamp the bits. £100 a day for each bit should do. Quote Link to comment Share on other sites More sharing options...

flytilbroke Posted September 22, 2011 Share Posted September 22, 2011 I find a bit of it I shall charge quite high storage fees as no prior contract existed.

Terence Lynock Posted September 23, 2011 Share Posted September 23, 2011 Well, if its anything like the two communications sattelites we had on display at Cosford some years ago there is quite a few quids worth of scrap metal there, everything is gold plated, all contacts are platignum and as this ball of fun was built before solid state gadgetery and surface mount components it will have a lot of other goodies too.

Peter Miller Posted September 23, 2011 Share Posted September 23, 2011 The odds are a bit worrying. I am sure that I have heard and seen the statement that you only have a 1 in 3500 chance of being hit. Now I know that my maths are not brilliant but if one person in 3500 is going to be hit and there are seven billion people on earth my calculators says that 2 million are going to get hit. I wonder how high their insurance premuims are!!!! Quote Link to comment Share on other sites More sharing options...
Lazygit Posted September 23, 2011 Share Posted September 23, 2011 The statement was that there was a chance of 1:3200 of a person being hit, so instead of multiplying you should have divided, ie 1/(3.2x10^3x7x10^9) = 1:22.4x10^12 for any one individual. How the hell they worked that one I don't know. Sounds like some gross assumptions were made. Maybe BBC's "More or Less" could tell us.

I wonder how high their insurance premuims are!!!! Wooooaaaa there. I think that the probability was that there was a one in 3500 chance that anybody would be hit, not that any one person would be. And the insurance companies would find a weaset out of paying anyway!

andy watson Posted September 23, 2011 Share Posted September 23, 2011 The maths is pretty easy on this one- if you can be bothered. Average person has an area of say 1 square foot. 9 billion people = 9 billion square feet covered by people. Surface of the Earth = XXXXXXXX Odds of someone getting hit = 9 Billion /XXXXXXXX Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted September 23, 2011 Author Share Posted September 23, 2011 It's a bit more complex than that Andy - the swept area is only between about 57 degrees North and 57 degrees south and the vast majority of the earth's population live within this area.
