Space Boat: A Nautical Mission to an Alien Sea
The Titan Mare Explorer: A nautical mission to an alien sea.
If [NASA] green-lights the mission, the capsule will lift off in 2016. By 2023, TiME will be about 800 million miles away in Titan’s north-polar region, home to its biggest lakes and seas. The capsule will take photographs, collect meteorological data, measure depth, and analyze samples. TiME will have no means of propulsion once it is on Titan, so it will float, carried by breezes across the sea’s surface. Then, by the mid-2020s, it will enter a decade-long winter of darkness as the moon’s orbit takes it to the dark side of Saturn, away from the sun and communication. It won’t have a line of sight to Earth to beam back more data until 2035.

Using a solar sail to deflect an earth-destroying asteroid
In a paper published today on the Los Alamos astro-ph preprint website, two Chinese scientists have proposed using a solar sail for deflecting any asteroid that happens to be aimed at the earth. The diagram to the right is their simulated mission to impact the asteroid Apophis, which will pass close to the earth in 2029 and — depending on whether that flyby puts it through a very small 600 meter-wide mathematical “keyhole” — could then return in 2036 on a collision course.
The idea is to use the sail to slow the spacecraft down enough so that it starts to fall towards the sun. The sail is then used to maneuver it into a retrograde orbit. When it impacts the asteroid the impact will therefore be similar to a head-on collision, thereby imputing the most energy in the least amount of time with the least amount of rocket fuel. In their Apophis simulation, a mission, weighing only 10 kilograms (about 22 pounds), launched around 2025, and hitting the asteroid in this manner in 2026, would deflect its flyby in 2029 enough to guarantee it will not fly through the “keyhole” and therefore eliminate any chance of it hitting the earth in 2036.
Obviously many questions must be answered before such a mission should fly.

American manned space: dependent on the Russians in more ways than you think.
As commentators from around the country gnash their teeth at U.S. dependence upon Russia to move cargo and astronauts to the mostly U.S. built/funded International Space Station (ISS), they’ve missed the bigger boat: With one exception, all the commercial spaceflight offerings currently in the works have Soviet or Russian engines as a key part of the rockets involved.

Some questions about today’s hypersonic test flight
Here are some additional stories describing today’s test flight of the Hypersonic Test Vehicle.
- Los Angeles Times: Falcon hypersonic vehicle test flight fails
- Aviation Week: Telemetry Lost During Hypersonic Test Flight
- DARPA: HTV-2 collects unique data during several phases of second flight
I have several questions, and no answers:
Contact quickly lost during third test flight of hypersonic plane
Contact was quickly lost today soon after a hypersonic glider was released by its rocket launcher during a test flight. More here.

The state of the Himalayan glaciers
A new study of the glaciers of the Himalayas by the Indian Space Research Organization and the Geological Survey of India has found that, based on satellite data, 2184 were retreating, 435 were advancing, and 148 showed no change.
It is refreshing that the scientists and politicians involved in India refused to cite global warming as a cause, referring instead to the “natural cyclic process”. As India’s former environment minister Jairam Ramesh noted, “There is no doubt that the general health of the Himalayan glaciers is worsening, but the truth is incredibly complex.”

Endeavour Crater at last!
The science team for the rover Opportunity have released their first image taken from the rim of Endeavour Crater.
Since this picture looks south from Spirit Point less than a football field’s distance from the rim, it appears to look into the crater, the mountains on the right being the crater’s rim. What looks like a debris field running across the center of the image looks to me to be a combination of exposed patches of bedrock and boulders on the plateau above the rim. For the scientists, those boulders will be the prime research targets, as they are possibly ejecta produced at crater impact and could therefore be material thrown out from deep within the Martian crust.
A Department of Innovation logo that can’t work
You can’t make this stuff up: Michelle Malkin points out that the logo created by Smithsonian’s Department of Innovation shows a gear arrangement that simply can’t function in the real world.
Check out the logo. 3 interlocking gears arranged in this fashion will not move in any direction. They are essentially locked in place. Which when you think about it, is a perfect analogy of today’s government!
The comments on the Department of Innovation’s own webpage are hilarious as well:
Perhaps this should be the new logo for Congress….since no motion could come from this arrangement.

Stand by for space weather
Stand by for space weather: three coronal mass ejections were released by the sun in the past few days and are aimed directly at the earth. The first hit tonight, without doing much damage.
Though it is important to prepare for these solar storms, don’t expect them to do much harm. Power companies use the warnings to protect their grids. What you can expect is an increased chance of seeing the aurora at lower latitudes.
