Croatian software developer and amateur image processor Gordan Ugarković takes images from NASA's unmanned space probes released to the Planetary Data System, splices them together and tweaks the colors, sometimes combining higher resolution black and white images with color images, sometimes recreating what the object would look like in natural color (ie, in visible wavelengths, from images taken in multiple wavelengths), sometimes heightening the contrast to bring out detail.

The concept of time as a way to measure the duration of events is not only deeply intuitive, it also plays an important role in our mathematical descriptions of physical systems. For instance, we define an object’s speed as its displacement per a given time. But some researchers theorize that this Newtonian idea of time as an absolute quantity that flows on its own, along with the idea that time is the fourth dimension of spacetime, are incorrect. They propose to replace these concepts of time with a view that corresponds more accurately to the physical world: time as a measure of the numerical order of change.

First Orbit. "On 12th April 2011 it will be 50 years to the day since Yuri Gagarin climbed into his space ship and was launched into space. It took him just 108 minutes to orbit Earth and he returned as the World's very first space man. To mark this historic flight we have teamed up with the astronauts onboard the International Space Station to film a new view of what Yuri would have seen as he travelled around the planet. Weaving these new views together with historic voice recordings from Yuri's flight and an original score by composer Philip Sheppard, we have created a spellbinding film to share with people around the World on this historic anniversary."

As they leave the solar system, the Pioneer spacecraft have anomalously decelerated, pointing to a possible gap in our understanding of gravity. Now, a computer graphics technique known as Phong shading predicts that the Pioneer anomaly is just a side effect of how the shape of the spacecraft reflects sunlight.
The Van Allen Belt is a pesky radioactive torus surrounding Earth. Spacecraft operating for extended periods within it must use heavy and expensive radiation hardening techniques just to survive. Tethers Unlimited has proposed a rather daring scheme for circumventing this nuisance: HiVOLT. [more inside]
In 1967, Cosmonaut Vladimir Komarov went up in a capsule he knew would never get back (NSFW gruesome image) to earth in one piece. He could have bowed out of the mission, but that would meant his good friend, Yuri Gagarin (the first man in space) would have drawn the mission instead. So Vladamir launched knowing it was a suicide mission. The CIA was listening in , and recorded what may have been Vladimir Komarov's last words, amid cries of rage. Adding to the tragedy, Yuri died in a plane crash the next year.
"The Earth tide is a little-known daily event, similar to the oceans' more familiar tides. But the sun and moon's gravity doesn’t just pull on water, it deforms the Earth itself, causing the ground beneath us to bulge toward the pulling heavenly body." [more inside]
You Never Get a Seventh Chance to Make a First Impression: An Awkward History of Our Space Transmissions
Dr. Hoover has discovered evidence of microfossils similar to Cyanobacteria in freshly fractured slices of the interior surfaces of the Alais, Ivuna, and Orgueil CI1 carbonaceous meteorites. The scientist's conclusion is that the fossilized bacteria are not Earthly contaminants but are the fossilized remains of living organisms which lived in the parent bodies of these meteors, e.g. comets, moons, and other astral bodies. The implications are that life is everywhere, and that life on Earth may have come from other planets.

Apollo 14, with Alan Shepard, American's first man in space, as the Commander, Stuart Roosa, Command Module Pilot and Edgar Mitchell, lunar module pilot, splashed down forty years ago today. It was flight of the rookies (total previous time in space was 15 minutes, all by Shepard). There were several odd things about the flight, but no need to worry, the moon trees are doing just fine.
Several months ago, Bill Rankin of Radical Cartography (previously and previouslier) created an astronomical calendar of events for New Haven, Connecticut, where he lives, featuring all of the inexorable rhythms of the Solar System in one handy PNG file. Now you can create such a calendar for any location on the planet, with information as basic as the hours of daylight or as esoteric as the tilt of Saturn's rings, all lovingly rendered in soothing translucent pastels.

Challenger . . . . go with throttle up. Twenty-five years ago today the U.S. Space Shuttle Challenger exploded 73 seconds into the 25th space shuttle flight. The reports (pdf) tell us of O-Ring failures. Today, we remember one of the most tragic days in the history of the U.S. manned spaceflight program. Today, January 28, 2011, we remember: Michael Smith, Dick Scobee, Judith Resnik, Ronald McNair, Ellison Onizuka, Gregory Jarvis, and Christa McAuliffe.

"The theme of this blog is not only and obviously space, but in particular places in space that a person might theoretically be able to one day visit. So for the most part, nebula, galaxies and the like are not a part of this forum. I tend to focus on “terrestrial” places or places that host such places. I suppose I would like to find out more about these places that we may one day inhabit or simply visit."

Slate says putting more than one space between sentences is "totally, completely, utterly, and inarguably wrong." Microsoft's Bill Hall agrees. LaTex does not.

Dmitar Sasselov is an astrophysicist, Director of the Origins of Life Initiative at Harvard and a co-investigator of the Kepler space telescope project to find Earth-like planets around the Cygnus constellation and discover extraterrestrial life. But no matter how successful the Kepler project may be, it still won't answer the most fundamental questions of astrobiology: How diverse is life in the universe? If alien life exists, will it have Earthly DNA and proteins? Or will it run on something else? So Dr. Sasselov has decided to collaborate with two synthetic biologists, asking them to create a life form based on mirror-image versions of what we know as the essential building blocks of living things on Earth.

Built as part of the fifth /dev/fort developer retreat, Spacelog.org allows you to explore early space missions via the original NASA transcripts. Currently live are Mercury 6 which made John Glenn the first American in orbit, and the 'successful failure' Apollo 13 (The transcribed key moment and the original). Alongside the transcripts are supporting materials from the NASA archives including photography and descriptions of the mission phases. The developers are looking for help to digitise the Gemini 7, Apollo 8 and Apollo 11 missions.
