What does this mean for space exploration?

Once considered a dry, hostile place, confirmation that there is water ice on the moon's surface makes it a favourable place for space exploration, Dr O'Neill said.

"What that means for us from an engineering point of view, and a practical point of view we know now the moon definitely has these resources.

"We actually have water there, so we don't have to bring it with us, which cuts down launch costs immensely.

"It makes the moon a lot more feasible in terms of human colonisation or just using it as a mission base for the rest of the solar system as well."

Dr Li said their research provided a clear map of where to find water ice in the polar regions.

But for now, he said, we still have a large knowledge gap about these dark, freezing regions.

"We've been studying the moon since before the Apollo era ... but we've barely touched the polar parts of the moon," he said.

"In the future, I think it's worth sending a mission that focuses on the polar regions to look at those dark regions to see what's going on there."

The only mission to come close in the near future will be the Korean Pathfinder Orbiter.

Due to launch in 2020, it will be kitted out with a NASA-built camera known as ShadowCam.

The camera is designed to peer inside permanently shaded craters near the poles, but its cameras will not operate at wavelengths to detect water ice, Dr Li said.

Katherine Coleman Goble Johnson (born August 26, 1918) is a mathematician whose calculations of orbital mechanics as a NASAemployee were critical to the success of the first and subsequent U.S. manned spaceflights. During her 35-year career at NASA and its predecessor, she earned a reputation for mastering complex manual calculations and helped the space agency pioneer the use of computers to perform the tasks. Her work included calculating trajectories, launch windows and emergency return paths for Project Mercury spaceflights, including those of astronauts Alan Shepard, the first American in space, and John Glenn, the first American in orbit, and rendezevous paths for the Apollo lunar lander and command module on flights to the Moon.[2][3][4] Her calculations were also essential to the beginning of the Space Shuttle program,[2] and she worked on plans for

I wonder if this is the morality cell...

Well than it is lacking a lot!

Science continues to get things backwards.

I like to use a book as a metaphor. The paper and ink represent the material world and the words on the page represent consciousness. No amount of ink and no kind of paper can take the place of the words.

The words are the essence of the book. The paper and ink are incidental. If they are destroyed, the book simply reappears in a different form -- a copy, or an e-book, for example. The book exists in the author's mind and heart long before it takes material form.

The material world cannot create consciousness. But consciousness, using perception and imagination, can create the material world.

The table in front of me is part of the material world -- is it not? For me, this table is material; it exists. It is hard, solid. But a physicist who examines it finds mainly empty space: Where I see a table, he sees atoms. Where does the table come from, then? It comes from consciousness, from imagination.

I have been to a rather wet party and just got home to read your post . It is an interesting concept but tonight I disqualify myself from answering in depth. See you tomorrow.

New planet 'the Goblin' discovered in outer solar system

Goblin dwarf planet

A dwarf planet nicknamed the Goblin has been discovered well beyond Pluto, further redefining our solar system.

Key points:

  • Frozen dwarf planet about 300km across was discovered on the outskirts of our solar system with an elongated orbit
  • Dubbed 'the Goblin', it was discovered in 2015 around Halloween, but has only now been publicly unveiled
  • At its most distant, the Goblin is 2,300 times further from the sun than Earth is

A round frozen world just 300 kilometres across, the Goblin was spotted by astronomers in 2015 around Halloween, thus its spooky name. But it wasn't publicly unveiled until now following further observations with ground telescopes.

One of the astronomers who made the discovery, Scott Sheppard of the Carnegie Institution for Science, said the Goblin was on the small end for a dwarf planet. It is officially known as 2015 TG387 by the International Astronomical Union's Minor Planet Centre.

This is the third dwarf planet recently found to be orbiting on the frigid fringes of our solar system.

Goblin's orbit is extremely elongated — so stretched out, in fact, that it takes 40,000 years for it to circle the sun.

At its most distant, the Goblin is 2,300 times further from the sun than Earth. That's 2,300 astronomical units (AU). One AU is the distance from Earth to the sun, or roughly 150 million kilometres.

At its closest, the Goblin is 65 times farther from the sun than Earth, or 65 AU. Pluto, by comparison, is approximately between 30 and 50 AU.

Dr Sheppard, along with Northern Arizona University's Chad Trujillo and the University of Hawaii's David Tholen, spotted the Goblin in October 2015 when it was relatively nearby — around 80 AU.

Scientists still pursuing elusive 'Planet X'

The two other dwarf planets are Sedna, discovered in 2003, which is about 1,000km across, and 2012 VP113, about 500km across. They were found by some of the same astronomers.

Thousands — even a million — more such objects could be way out there orbiting in the so-called Inner Oort Cloud, according to the researchers. They're in hot pursuit of them, as well as a potentially bigger-than-Earth planet known as Planet 9, or Planet X, believed by some scientists to be orbiting at a distance of hundreds of AU.

These objects are on elongated orbits, and we can only detect them when they are closest to the Sun. For some 99 per cent of their orbits, they are too distant and thus too faint for us to observe them. We are only seeing the tip of the iceberg," Dr Sheppard said.

Dr Sheppard said the faraway objects were "like breadcrumbs leading us to Planet X."

"The more of them we can find, the better we can understand the outer solar system and the possible planet that we think is shaping their orbits — a discovery that would redefine our knowledge of the solar system's evolution," he said in a statement.
