The Japanese space agency has unveiled an incredible new plan to start collecting solar power in space, and zap it down to Earth via microwaves or laser beams.

Under the plan, known as the Space Solar Power System (SSPS), floating photovoltaic dishes several square miles across would hover in geostationary orbit outside the Earth’s atmosphere as soon as 2030.

According to a researcher at Mitsubishi Heavy Industries, one of the project participants, “Since solar power is a clean and inexhaustible energy source, we believe that this system will be able to help solve the problems of energy shortage and global warming. The sun’s rays abound in space.” (Another picture after the jump).

When I first read the news that NASA was going to start experimenting on monkeys with radiation to study the effects of deep space travel, my heart sunk. As an anthropologist who has studied non-human primates I have seen up close the emotions, the feelings, and the physical qualities we share with our evolutionary cousins. My mind went back to shooting chimps into space, not caring if they lived or died. To cruel (and now illegal) experiments of all kinds performed on our closest living relative.

Now NASA is planing to irradiate squirrel monkeys. Scientists are particularly interested in studying how the radiation impacts the monkeys’ central nervous systems and behaviors over time. Messing with the monkeys brains. Oh great!

Google Inc. is joining forces with space agencies around the world and the conservation organization Group on Earth Observations (GEO) to monitor deforestation rates using satellite imagery. Among the space agencies working on the program are NASA, the ESA, and the national space agencies of Japan, Germany, Italy, India, and Brazil.

The GEO is a global partnership of 80 governments and more than 50 organizations. Internet company Google currently collects satellite images for use in its Google Earth application, and will be providing satellite images to the project.

Scientists have discovered that sunspots are not the only thing from the Sun that have a significant and varied impact on the Earth.

There is a “solar cycle” of approximately 11 years. Variation of the Sun’s impact on the Earth during those 11 years is generally thought to be due to sunspots. The Sun also shoots high-speed winds at the Earth, however, and scientists have just discovered that these super winds significantly affect the Earth in several ways.

It maybe happening in space but people are still screaming. NASA’s mission to fire a high velocity “impactor” rocket into the moon to search for water is being widely criticized in the blogosphere.

The moon’s big bang

If NASA’s plans go ahead as forecast for an October 9 launch people have got just two more opportunities to watch a full moon before the planet is subject to what many consider mightily unneighbourly conduct.

Japan is planning to build a solar power station in space within the next 30 years. It is expected to cost $21 billion. How will they do it?

Millions of nuts, bolts, pieces of metal and carbon, and whole spacecraft from thousands of missions and launches form an orbiting garbage dump spinning around the Earth at speeds up to 22,000 mph.

After the recent collision between a Russian and U.S. satellite, concern for the growing hazard of space junk is becoming even more acute within the international space community. In recent months, NASA and the European Space Agency have both diverted resources into monitoring space debris and researching ways of mitigating and—some day—removing it.

Gliese 581 d. Such a catchy name eh? You probably have never heard of it. It is 20 light years away, but in late April 2009 new observations by the original discovery team concluded that the planet is within the habitable zone where liquid water, and therefore, life, could exist.

Some of you may have heard of SETI. SETI or Search for Extraterrestrial Intelligence, conducts legitimate science research, searching for extraterrestrial life by looking for some signature of its technology. For years people have been sending radio waves into space on the off chance that there will be a response. Beatles songs, TV shows, radio broadcasts have all been shot into space. Now an Australian website is letting you text into space.

Lately the long foggy nights of summer make me wistfully yearn for the drive-in movies of my youth. Bad movies and sticky salty gooey food were merely condiments for the socializing that was really the main event on so many long ago August nights. Sadly, all of our local Bay Area drive-ins have gone dark years ago; however, this summer in San Francisco we now have something even better, the bike-in movies.

Throughout this summer the San Francisco Bicycle Coalition is hosting a series of free bike-related movie screenings downtown at 7th and Mission Streets, right across from the Good Hotel. Once a month the hotel’s barren parking lot is transformed into a festive and inviting public space, where hundreds of people gather for free entertainment, socializing, and to eat tasty locally made snacks.

July 20th, 2009 was the 40th anniversary of Apollo 11’s historic flight to the moon, where astronauts Neil Armstrong and Buzz Aldrin became the first human beings to walk on the moon. 40 years ago, space flight inspired such awe that astronauts were hailed as heroes and celebrities by men, women, and children alike. 40 years later none of us, besides the most avid space fanatic, would likely to be able to name one astronaut in service today.

Despite the tragedies of Space Shuttle Challenger, and later Columbia, where the world is shocked into being reminded of the inherit dangers of sitting on 1 million gallons of rocket fuel, or re-entering the earth’s atmosphere at 1,870 miles per hour. We all see space flight as mundane because the vast majority of space flights since Apollo 11, have been mostly conducting seemingly routine scientific experiments. Now don’t get me wrong, I believe in the importance of science in space, but these experiments don’t exactly inspire awe in the general population like, oh say, a manned mission to Mars would. We also don’t have the fever of beating those damned Ruskies because they might go to space and blow us all up, which we had during the height of the cold war when Apollo 11 touched down on the lunar Sea of Tranquility.

That was one of the many probing questions that the visionary former mayor of Bogotá Colombia, Enrique Peñalosa, asked a packed auditorium in San Francisco last night. How do we define what makes a good city, what is our criteria? What makes an urban environment desirable and livable, and how do we judge the quality of life? What is socially and environmentally sustainable?
