The Ultimate Project: 10000 Year Journey

When you’re thinking interstellar, long time frames are inescapable. Are we capable as a culture of planning missions that last not only longer than a single human lifetime, but longer than multiple generations? Steve Kilston (Ball Aerospace & Technologies), with help from Sven and Nancy Grenander, clearly thinks so. The three are behind the fittingly named Ultimate Project, a starship designed to carry one million humans across the light years separating us from the nearest stars, creating colonies and perhaps going on from there, a ten thousand year star journey that could turn into a trek through the galaxy lasting for millions more.

It looks like this one, clouds permitting, will be visible across most of the US, running from 8:43p Eastern on 2/20 to about midnight.

If We Had No Moon

If the time of Earth’s existence was condensed into a 24-hour clock, the moon formation event occurred just 10 minutes after the Earth was born. The Earth formed 4.56 billion years ago, and the Moon formed about 30 million years later. At that time, the Earth was a magma ocean. An impactor about the size of Mars struck the Earth at an oblique angle, and removed some of the magmatic mantle. This mantle was put in orbit around the Earth, together with some of the debris from the impactor itself, and this material eventually formed the Moon.

He doesn’t mention the nifty Cat Stevens song we’d be missing.

Simulated Worlds

A few years before the first landing of an Apollo crew on the moon, scientists recontoured a volcanic field just outside of Flagstaff, Arizona, with artificial impact craters resembling those found on Mare Tranquillitatis, the proposed first manned American landing site.

With high explosives, they terraformed a lunar surrogate right here on the surface of the earth.

This is interesting, I never knew about this training ground. Neat stuff.
