"What a beautiful world this will be. What a glorious time to be free."

It's been nearly 50 years since the beginning of the International Geophysical Year (IGY), an 18-month period of scientific activities and discoveries that ran from July 1, 1957, to December 31, 1958. Both the US and the USSR launched the world's first artificial satellites during the IGY (Sputnik 1 and Explorer 1). Other achievements of the IGY included the discovery of the Van Allen radiation belts and the mapping of mid-ocean ridges. The IGY also inspired at least one artistic endeavor: Steely Dan's Donald Fagen wrote his 1982 solo song "I.G.Y. (International Geophysical Year)" [YouTube] as an homage to 50s optimism.

Breaking: Science fiction is fiction

Ruining science fiction: Not only are the science fiction cliches humorously skewered in the Tough Guide to the Known Galaxy, but the science itself is wrong. For example, despite the best efforts of SF writers, interstellar trade will never work, unless wine costs $11 billion a bottle. Slower-than-light travel is much harder than you think, and warp drives are far away. Space battles, if they happen, won't have fighters and dramatic dogfights, but instead involve vast distances and maneuvers lasting years. And you can ruin a whole lot more science fiction with real science (and wonderful examples) at Atomic Rocket. Don't follow the links if you want to read Heinlein or watch Battlestar Galactica with a light heart.

Space 199NOW

We could wait for NASA to build that permanent moon base they keep promising. Or we could just turn our apartments on earth into our own moon bases, space ships, or spy pads.

"We're space explorers, and we need space!"

Where did you want to live when you grew up? If you're like me, you read Clarke's SF classic, Rendezvous with Rama (soon to be a major motion picture?). Donald E. Davis took what we dreamed about and illustrated it, for NASA. His depictions of O'Neill Cylinders, Stanford Tori, and Bernal Spheres are in the public domain (and make excellent desktop wallpaper).

The Lights in the Sky Are Stars

Universe Today is a news site for astronomy geeks. Don't miss its sibling, the Bad Astronomy Forum, which not only features examples of bad astronomy, but also discussions of space exploration and astrophotography. (If you like astrophotography, you're probably already aware of NASA's astronomy photo of the day.) But my favorite part of the whole site is the free astronomy eBook, What's Up 2007: 365 Days of Skywatching. If only it would only stop raining, maybe I'd grab some binoculars and go outside for some stargazing...

Moonbase: Alpha

NASA Plans Permanent Moonbase. The base, a potential stepping stone for further Mars exploration, will likely be situated near one of the poles. The advantages of a polar site (pdf) include a relatively moderate climate, possible hydrogen and oxygen resources, unexplored terrain and abundant solar power. They have apparently abandoned plans to use nuclear reactors, which is probably for the best.

Convert moon rocks to oxygen and other ways to earn $250,000

The NASA Centennial Challenges: Inspired by the X-Prize, NASA has begun a series of challenges to private inventors with cash prizes for things ranging from extracting oxygen from moon rocks to building better astronaut gloves to improving personal aircraft. Thanks to Congressional approval, NASA will be launching larger challenges of up to $50 million in value, including a new multi-million dollar lunar lander contest. With government space efforts criticized by private entrepreneurs, is this the right direction for NASA?

Pioneer Anomaly

The Pioneer Anomaly. Something's up in deep space: the Pioneer spacecraft, now out of contact, have shown an unexplained Doppler drift, indicating sunward acceleration, effectively decelerating the probes cumulatively. The effect may be be nongravitational, and could be explained by any number of factors: an undiscovered twist in Newtonian physics, localized cosmological contraction issues, or just venting gas. Other deep space probes may have experienced the anomaly as well, and a new mission could explore the puzzle; but for now, all we have is past Pioneer data, and that's stored on old 9 track tape which can only be read by antique readers. What's to be done? (Also see Pioneer Odyssey for a nostalgic romp through those early days of deep space exploration. And NASA, bring back the original Pioneer home page plz, kthx.)

Huygens Makes it!

It worked! Huygens has successfully landed on Saturn's moon Titan and the Cassini orbiter is sending good data back to Earth as I type. Isn't it amazing how we can take a probe the size of a compact car, send it on a 7 year journey in the most inhospitable environment imaginable, deploy a sub-probe that has been dormant for that entire time and land it where we had planned on another solar body so far away that it takes 67 minutes to get a signal back and forth. Exploration and research has never been so cool.

Life On Mars's Meethane Traces Thought To Be Detected

Life on Mars? Methane has been found in the Martian atmosphere which scientists say could be a sign of present-day life on Mars. It was detected by telescopes on Earth and has recently been confirmed by instruments onboard the European Space Agency's orbiting Mars Express craft. Methane lives for a short time in the Martian atmosphere so it must be being constantly replenished. There are two possible ways to do this. Either active volcanoes, but none have yet been found on Mars, or microbes. The Independent has it as Methane find on Mars may be sign of life. The second group to detect signals of methane in the Martian atmosphere is led by Michael Mumma of Nasa's Goddard Space Flight Centre in Maryland, who used powerful spectroscopic telescopes based on Earth. This team is even believed to have detected variations in the concentrations of methane, with a peak coming from the ancient Martian seabed of Meridiani Planum, which is being explored by a Nasa rover. This could indicate a subterranean source of methane which is pumping out the gas, either due to some residual geological activity or because of the presence of living organisms producing it as a waste gas. Asked whether the continual production of methane is strong evidence of a biological origin of the gas, Dr Mumma said: "I think it is, myself personally." As to how...

Martian Sea

Old Mars and the Sea. A salty sea may once have covered the Opportunity rover's landing site on Mars, boosting the possibility that the planet may once have evolved life. (Of course, there are those who believe NASA has been conspiring to cover it all up, but the Bad Astronomer has words on that. Bunnies and faces, my foot.)

Spitzer Space Telescope

The first images from the Spitzer Space Telescope, formerly known as the Space Infrared Telescope Facility and renamed after astrophysicist Lyman Spitzer, Jr., were released on Thursday. Launched on August 25, it obtains images by detecting the infrared energy radiated by objects in space, and it will drift behind the Earth as the planet orbits the sun.

Talk about Johnny One-Note

In space, you can hear a black hole sing (WaPo link). Using the Chandra X-Ray Observatory, astrophysicists have detected a supermassive black hole in the Perseus Cluster which has been "playing" a B-flat for 3 billion years.

Fascinating as this seemingly counterintuitive discovery (sound carrying through space) is, the real significance lies in that these "sound waves" may explain why the superhot gases in such regions aren't cooling down and forming more stars.

Orbiter

Orbiter - A Free Space Flight Simulator Starving for a high realism space simulator ever since Microsoft's Space Simulator was discontinued? Look no further than Orbiter, a free realistic space simulator written and maintained by Dr. Martin Schweiger. How realistic? You might want to start off by consulting NASA's Jet Propulsion Laboratory's Basics Of Space Flight to get you grounded so to speak. This is a free, non-commercial simulator that uses accurate math and orbital physics (more or less) to try to model space flight. However hard it may appear, after orbiting Earth with the high-res (8192x4096) mod-pack installed, or sitting on the launch pad with the seamless OrbiterSound 2.1b sound environment installed, you will be well rewarded for reading the manual and participating in the dance of the heavens. (Even if all you want to do is fly around the solar system!)

Aonther massive celestial object, with a companion star in tow,

Another massive celestial object, with a companion star in tow, has been discovered hurtling through the Milky Way. Unlike similar discoveries confirming the bow shock theory of stellar dynamics, this week's phenomenon is considerably older, as it's an aftereffect of the galactic core's formation. The French and Argentine astromoners making the discovery believe what they've witnessed may be a black hole, though theoretically, the collasped matter may be a gravistar.
