Colonization of the Moon

1986 artist concept The colonization of the Moon is the proposed establishment of permanent human communities or robot industries[1] on the Moon. Recent indication that water might be present in noteworthy quantities at the lunar poles has renewed interest in the Moon. Polar colonies could also avoid the problem of long lunar nights – about 354 hours,[2] a little more than two weeks – and take advantage of the sun continuously, at least during the local summer (there is no data for the winter yet).[3] Permanent human habitation on a planetary body other than the Earth is one of science fiction's most prevalent themes. As technology has advanced, and concerns about the future of humanity on Earth have increased, the argument that space colonization is an achievable and worthwhile goal has gained momentum.[4][5] Because of its proximity to Earth, the Moon has been seen as the most obvious natural expansion after Earth. Proposals[edit] In 1954, science-fiction author Arthur C.

Extraterrestrial Life The official U.S. government position on extraterrestrial life and the three major efforts to search for it. Clockwise from top left: The development and testing of hypotheses on extraterrestrial life is known as "exobiology" or "astrobiology", although astrobiology also considers Earth-based life in its astronomical context. Many scientists consider extraterrestrial life plausible, but there is no direct evidence of its existence.[2] Since the mid-20th century, there has been an ongoing search for signs of extraterrestrial life, from radios used to detect possible extraterrestrial signals, to telescopes used to search for potentially habitable extrasolar planets.[3] It has also played a major role in works of science fiction.

Finding Life Beyond Earth PBS Airdate: October 19, 2011 NARRATOR: Is Earth the only planet of its kind in the universe, or is there somewhere else like this out there? Is there life beyond Earth? An Illustrated Guide to Space Maps Nebra Sky Disc, Germany, 1600 BC. (Photo: Rainer Zenz/WikiCommons CC BY-SA 3.0) With its patinated bronze background and shiny gold sun, moon and stars, the 3600-year-old Nebra Sky Disc is worth gazing at for its beauty alone. But the ancient object is cool for a lot of other reasons: It’s the earliest depiction of outer space we’ve ever found, and it’s also thought to be the oldest known portable astronomical instrument.

Many vulnerable people denied care, says Age UK 5 March 2014Last updated at 22:10 ET By Nick Triggle Health correspondent, BBC News A "catastrophic" situation is developing in England with many vulnerable elderly people being denied care, campaigners say. An analysis by Age UK found the proportion of over-65s getting help had fallen by a third since 2005-6. Last year, under 900,000 over-65s got help - one in 10 people in that group - compared with 15% seven years ago. The review - based on published data - estimated at least 800,000 older people were going without vital help.

planets - How would having multiple moons affect tides? - Worldbuilding Stack Exchange You can model the effect of two moons by summing two sine waves. To do this plot each moon as a function of Time and manipulate the gravity of the moon by changing the amplitude and the orbital period by multiplying the time variable. A final plot showing the summation of the others gives the resulting forces on the tides. Long Version Why the USA and NASA need astrobiology I am an astrobiologist, for 50 years an astronomer, and before that a physicist. With my colleague and friend Roger Angel, we started the process of learning how to detect Earth-like planets in 1985. I am a co-author of the NASA booklet The Terrestrial Planet Finder.

A One-World Government ________________ By Benjamin Seiler In July 1969, the American President Nixon held a historic address before Congress. In this first speech on the issue of population, he said: “One of the most serious challenges to human destiny in the last third of this century will be the growth of the population.”
