NASA Common Extensible Cryogenic Engine

Icicles! On an engine that burns at 5000 degress!

A technology development engine that may help NASA safely return astronauts to the lunar surface has successfully completed its third round of testing. The goal of these tests is to reduce risk and advance technology for a reliable and robust rocket engine that could enable America’s next moon landing.

The tests by Pratt & Whitney Rocketdyne in West Palm Beach, Fla., helped to gather data on this concept engine that might play a role in the next stage of human exploration of the moon. Most rockets make spacecraft travel faster. The goal of a lunar lander descent engine is to slow the vehicle so astronauts can land safely.

Palm Pre

[This has been in my drafts since January 9, only noticed it now. It does have a motion sensor and landscape mode btw.]

The wife’ll kill me, I want one of these and I only have my Treo Pro a couple months.

Palm Pre

It seems to settle a major deficiency in the Treo Pro, namely Windows Mobile. It’s not a bad mobile OS per se, but the hardware is a tad underpowered for it, and it has niggles that can’t be addressed because of it’s closed nature. That said, I don’t know if the Pre’s webOS will be open either, but hopefully Palm will have generated Clue from their Windows adventure. And drop it forevermore…

One other apparent deficiency would appear to be a motion sensor and/or landscape mode. You’d think that if it had it, the presenter in these PC Pro videos – well worth watching by the way – would have demoed it; although it has to be said that despite best effort, he’s no Steve Jobs and might have been better off deferring to someone with more charisma.

Chicken Head Tracking

Probably my oddest post title yet!

Chickens have a great ability to keep their heads stable. Our bodies use a gyro-like mechanism in our ears which has 3 mutually orthogonal inertial measurement devices. Modern motion processors use something called an Inertial Measurment Unit (IMU). These devices provide movement data which can be used to compensate for the movement. Chickens apparently have the same type mechanism only with a higher update rate.
