    Purchase a Lovely New Home On...Mars?

    By Rachel Durfee Posted on 10.31.2008 17 Comments

    Buzz Aldrin is fondly remembered as the second man to ever step foot on the moon, after his more famous compatriot Neil Armstrong. The former astronaut, now 78, is back in the spotlight after proclaiming that, should the United States space program send a mission to Mars, those astronauts should be prepared to stay there.

    About that g-force, that only lasts for a short period of time, ships, rockets, shuttles or whatever they will send cant carry enough fuel to accelerate all the way to Mars, when a certain speed is reached the engine stops to accelerate and since there is no friction in space the speed would be maintained all the way.If we presume that the flight would take 1 year the "ship" would need to travel at a constant speed of 6296 km\h which is manageable since the fastest aircraft was the X-15 with the speed of 7,274 km/h in the atmosphere!. And life on mars will probably never be outdoors, because Mars is "small" the gravity isn't big enough to maintain a thick atmosphere therefor the pressure on mars is only one-hundredth of that on Earth, that means that one breath on Earth would be the same of hundred on Mars. I believe most of you think there would be electricity on mars, sure we would bring solar cells but like on Earth there are clouds and storms of great magnitude and that blocks the sunlight which is already weak because Mars is far from the Sun, I'm not sure but probably it would take a great amount of solar cells to maintain a biosphere, that is if they haven't found a way to minimize the cost of electricity for the air circulation, temp. regulation,water pumps or air or whatever they would use for toilets and so on. I don't know if they found a solution to all of these problems but I'm sure that there are a lot of problems that need to be solved before we can go to\live on Mars.

    Bigger Brains in Human Ancestors

    By Jaya Jiwatram Posted on 11.17.2008 4 Comments

    Researchers reveal that a 1.2 million-year-old female pelvis they found in Ethiopia in 2001 suggests our predecessors were larger-brained than previously thought The story of evolution got bigger last week when researchers revealed in the journal Science that they had discovered a wide-hipped pelvis, suggesting our ancestors were larger-brained than formerly thought. The first of its kind, the 1.2 million-year-old, near-complete female pelvis is from the now-extinct Homo erectus species, believed to be our first human-like relative to leave Africa.

    Why is it so important that we know when we evolved and how? I think its just about competition who will fill more blanks i our history.
