is too bad that these machines are all made by america
I don't mind that, the ones they produced have been more successful than any mission in history. Spirit and Opportunity landed on Mars in 2004, their primary mission lasted for about 3 months. The probes were expected to last for 2 years at most, but the rovers have lasted for 7 years. Spirit may not be responding, but Opportunity is still going strong.
mashallah this is another sign of allahs power,but these are not really plants,these things are already describe in the quran 1400 years ago,they are made so that shaitan and jinns cant get to the heaven,if they get close then these thing chase them away,is not a world like ours otherwise must have life and water
LOL. So, these things are meant to chase away the djinns? That's very enlightening. However, these are just pieces of dust and rock around a star, they don't chase away any thing, they come together to form a bigger piece of rock. I tried to make it as clear as possible, but it seems you're incapable of producing a coherent thought.
I keep hearing conflicting reports about whether or not bacterial life once existed on mars.
There was some media hype about finding life on Mars recently, it was sparked by scientists saying that Mars can support microscopic fossils, but that doesn't mean it has them. What they meant was, it's possible to have microscopic fossilisation on Mars, and that's something we can discover. This was picked up by the popular media and blown way out of proportion, classic sensationalism which is so common in the popular press, it's nothing new.
Are we any closer to finding this out for certain?
Well, there's lots of evidence to support that Mars was capable of supporting life in the past. It's very likely that there was life on Mars, and it still might be there,
check out the third paragraph. Curiosity is designed to evaluate if Mars was or still is capable of supporting life, there are 4 possible landing sites for Curiosity, none has been confirmed. It has a plethora of instruments on board, so it's going to be an interesting mission. This is our next step towards finding out if Mars had or still has life. So, step by step, we're getting closer to finally answering that question.
