Orbiting at 19 miles a second, so it's reckoned...

From Bklyn — Thu, 03 Dec 2009 02:11:59 -0800

Oh, so that's how that works. I never got the whole 'Mars in Retrograde' thing. This really helped. More than this description by Dr.Feynman of the elliptical orbit of the planets, and definitely more than this song-and-dance description of, well, the Universe.

Do gravity holes harbour planetary assassins?

Mission to Mercury

Artw — Mon, 14 Jan 2008 15:28:21 -0800

Mercury Messenger, a NASA probe, just performed a fly-by of Mercury at a height of 200 kilometers. It's the first spacecraft to visit Mercury since 1975.

Hot space bot uses stirling engine

NASA proposes using a Stirling cooler (essentially a Stirling engine in reverse) to keep a probe cool on the surface of Venus, which has had a tendency to melt or smash previous probes. The cooler would maintain a 25cm sphere within the probe at 200°C -- 100°C above the boiling point of water but sufficiently cool for a high-temperature microcontroller to operate. The waste heat radiators on the exterior of the sphere would reach the temperature of 500°C, 40°C above the the normal Venusian surface temperature.

Did the roof of the Pantheon influence Copernicus? Are the planets of the solar system aligned in accordance with a nearly-forgotten hypothesis known (unfairly) as Bode's Law? A fascinating wide-ranging discussion on BLDGBLOG with Walter Murch, the visionary editor and sound designer for such films as The Conversation, Apocalypse Now, The English Patient, THX1138, and many others. [Murch's film work has previously been discussed here and here.]

7 mph would be the equivalent of driving at the speed of light

At forty miles (64.4 km) from Pluto to Sun, the Maine Solar System Model is the largest complete three-dimensional scale model of the solar system in the world. What, you didn't know there was more than one? And yes, Pluto is staying put.

road trip, anyone?

Explore our local chunk of space. Here is a scale view of the Solar System, and here one can take a quick trip around it. Use the guidebook to plan your trip (but beware the pop-up ads). Don't forget to bring a camera and snap some photos.

Large rock named Huya! 3 years after being discovered a large object (?) orbiting the sun has been named.

Celestia: A free real time space simulation

Celestia is the most beautiful toy. It's a free (open source) simulator of the universe, including breathtaking models of known planets. Watch Jupiter rise over Io or follow the course of a solar eclipse. [more inside]

I saw all five of the visible planets in our solar system tonight! And so can you, if you have clear skies and go outside between 8:45 and 9 p.m. your time this week. Disclaimer - my naked eyes weren't good enough to see Mercury but I could see it with binoculars.

Reflections on a Mote of Dust "We succeeded in taking that picture [from deep space], and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam."
