...mars rovers again !











...do true modelling of mars rovers : around the moon first and back to earth...!

[["...On 6 August, the largest rover ever sent to Mars should touchdown on the planet’s surface. For the landing, the mission uses a complex – and untried – “sky crane”. Our space columnist finds out how it’s going to work. (Video of landing courtesy of Nasa).

If you’re contemplating a mission to Mars, Nasa’s Chronology of Mars Exploration makes depressing reading. For every successful Russian Mars 3 or American Viking 1, there’s a failed Beagle 2 (UK) or Mars Polar Lander (US). In fact only of the 42 missions listed, only 17 have been successful. The odds, over the past half-century, of a Mars mission succeeding are around 40%.

To be fair, several early missions didn’t even make it off the launch pad and the chances of success have improved considerably over the decades. But you don’t have to go back far to see failure. Only last year, Russia’s Phobos-Grunt mission to the Martian moon Phobos failed to make it out of Earth orbit (well, it did eventually when it burned up on re-entry). Perhaps the most infamous though is Nasa’s 1999 Mars Climate Orbiter, where a mix-up between imperial and metric measurements sent the spacecraft careering into the Martian atmosphere to be destroyed.

On 6 August (GMT) 2012 Nasa will try again with what is almost certainly the most ambitious and exciting Mars mission ever launched. The Mars Science Laboratory (MSL) with the Curiosity rover is designed to investigate whether the planet ever had the conditions to support life..."]]



... there is always a but, and sometimes a very big one...! and i was just thinking about it barely today...!

...I AM A GREAT BELIEVER IN MANY THINGS, and I like believing in myself, as most everybody else does...!
SO YOU ASK A REASON OR A BIG ENOUGH REASON WHY NOT TO BELIEVE, WITHOUT WANTING TO BE TOO NEGATIVE...!


And there you have it:

[1] I want to believe in the technological capacity of the USA, and I want to believe in Science in general, but when they do not do things as you would most obviously do them, it makes you wonder if they are that intelligent after all...!
 

[2] Why is there the need of any conspiracy ? There is nothing to hide in technology persee ! The rover was in plain "d-a-y-s-i-g-h-t" being tried on dessert ground, etc...!
 

[3] SO THE 10_MILLION DOLLAR QUESTION IS: Why not do the Rover to Mars, first to go around the MOON and back to land on Earth in a certain location of trial and error ? Would this be not more convincing ? You cannot allege lack of funds ! Would there be electronic interferences and sabotage ?
 

[4] WHAT IS WORSE, do the Rover to the MOON again, and then convince me of going to MARS...!




SORRY FOLKS I THINk WE ARE CLEARLY IN THE HANDS OF NOT SO INTELLIGENT EXPERTS OF USA, UK, AND RUSSIA...!

...the mars rovers is not much better than saying: we have seen the video of the rover on mars and the return of jesus to mars on his way to earth but says he is stranded there...!
