This week NASA spread the word that they have finally discovered water on asteroid 24 Themis, which they have been studying for 6 years. The theory that water was introduced from something off of the planet was a long-held theory, but now there is some evidence. The asteroid orbits the sun at a distance of 297 million miles, or between the planets of Jupiter and Mars and there is evidence of water ice and carbon-based organic materials.
“For a long time the thinking was that you couldn’t find a cup’s worth of water in the entire asteroid belt,” said Don Yeomans, manager of NASA’s Near-Earth Object Program Office, in a statement yesterday. “Today we know you not only could quench your thirst, but you just might be able to fill up every pool on Earth — and then some.”
What does this mean!?
It means that the story of the solar system will have to be updated and that asteroids themselves may be much more valuable than we previously thought.
“This is exciting because it provides us a better understanding about our past — and our possible future,” said Yeomans. “This research indicates that not only could asteroids be possible sources of raw materials, but they could be the fueling stations and watering holes for future interplanetary exploration.”
