Asteroid Belt And Earth On The Way To Mars

Spending a year in weightless space is a nightmare for the human body. But the push for Mars might have benefits closer to home. And robotic travel will harvest the asteroid belt. A few hundred years ago spices were scarce and literally gold. The asteroid belt could turn gold into a commodity.

Elon Musk’s New Plan: Travel from New Delhi to Tokyo in 30 Minutes https://t.co/KG8GeNq1vE

Delhi to Tokyo in 30 minutes, says Elon Musk. That translates to anywhere to anywhere on earth in 30 minutes. That is more alluring for human tourism (and commerce) than zooming vertically to the boundaries of from where all you see is pitch black before you come back.

But if you move information well enough, fast enough, in large enough quantities, securely enough, and from every point to every other point on earth, human beings perhaps can get by on less travel in the first place. The vision of 4,000 satellites carrying the bulk of internet traffic is sound. And it beats going to Mars. Such a spacenet would be indispensable for the Internet Of Things with its hundreds of billions of sensors, its top use being to keep the earthly ecosystem at its optimum best. Human safety and security would be a whole new paradigm.

Asteroid Mining

Mars Is Kind Of Far

What will humans do that robots can not? Mining the moon for energy is a better proposition, I think. But never say never.

The Deferred Dreams Of Mars

people communicating with a large and sophisticated piece of equipment 150 million miles away as it began to carry out experiments that should enhance our understanding of whether the planet has or has ever had life ..... six astronauts could be sent on six-month flights to Mars and what they would do there for a year and a half before their six-month flights home ...... NASA could perpetually remain 20 years away from a manned Mars mission. ..... a Mars crew would see Earth shrink into just one of billions of twinkles in space ..... the astronauts would have to survive in a freezing, windswept world with unbreathable air and 38 percent of Earth's gravity ...... systems for feeding them, sheltering them ..... the benefits are mostly intangible ..... right now Curiosity is exploring these very questions, firing lasers at rocks to determine their composition and hunting for signs of microbial life ..... Because of such robotic missions, our knowledge of Mars has improved so much in the past 15 years that it's become harder to make the case for sending humans. ...... "For the cost of sending one human to Mars, you could send an entire flotilla of robots." ....... the space shuttle would fly 135 times from 1981 through 2011 .... Going into space for more than two years would subject the astronauts to an unprecedented degree of isolation and extended weightlessness; the longest stay in space so far has been 14 months. Poten­tially deadly cosmic rays, which are blocked by Earth's magnetic field and atmosphere, would hit the spacecraft in flight and threaten the astronauts on Mars. ..... the sky crane used to land Curiosity wouldn't work for landing humans, whose craft could weigh 30 times more ...... something entirely new: protect and feed humans on another planet over a long stretch ...... "closed loop" life-support systems in which water and air are recycled ....... possible to extract oxygen from the carbon dioxide that makes up 95 percent of the Martian air. ..... dehydrated food that astronauts inject with water on the space station can retain adequate nutrients for five years ...... Pressure-treating the food ..... make the habitat inflatable, so it could be packed tightly en route to Mars. ...... the bone loss, blurry vision, and other problems astronauts suffer when removed from Earth's gravity ...... compared with the money and effort that get spent in the service of "greed and our ancestral urge to beat the crap out of each other." ...... colonizing the moon, stimulating space tourism, and harvesting solar energy from geosynchronous Earth orbit

Freefall From Space

I am more intrigued by how he went up then by how he came down. It did not take him all that long to get up there, did it? Lesson: travel light.
