Beagle landing


Several news sites are carrying accounts wherein Colin Pillinger, mission scientist for the UK's Beagle 2 Mars lander, says they've possibly located the crash site. In the last article, Guy Rennie, a 'photogrammetrist' and image analyst who was called in to examine images of the landing area, says:
[Beagle] has fallen precisely within the landing ellipse, in a crater that has a diameter of 18.5 metres. Had it landed just one metre to the north, we would expect to be communicating with it today.
One of the three segmented gas bags may have been damaged during impacts, causing it to deflate prematurely.

Pillinger is quoted in the Times article as saying that when the probe first hit the downslope of a small crater about 18.5m (60ft) in diameter, before crashing into its opposite wall, bouncing several times around the rim and eventually coming to rest at the bottom, 'It's a bit like hitting the side of the pocket in snooker.'

The BBC and some other sites are carrying this image of the crater and possible crash site:

BlogIt feature at physorg.com


I subscribe to the phys.org latest news RSS feed. In looking at the web page to the entry In new setback, Japanese asteroid probe to stay in space until 2010 about the Hayabusa mission to asteroid Itokawa, I noticed a link titled [Blog It]. Clicking on it opens a window with the html code for part of the story, which then can be copied and pasted. More helpful in some instances than viewing the source for the entire page.

NORAD go for tracking Santa


This will be the fiftieth year the North American Aerospace and Defense Command (NORAD) will track Santa by radar, satellites and camers, as he leaves the North Pole and enters Canadian and American airspace.
The moment our radar tells us that Santa has lifted off, we begin to use the same satellites that we use in providing warning of possible missile launches aimed at North America. ... The satellites have infrared sensors ... [and] Rudolph's nose gives off an infrared signature similar to a missile launch.

The third system we use is the Santa Cam. ... Santa Cams are ... high-speed digital cameras that are pre-positioned at many places around the world. NORAD only uses these cameras once a year - Christmas Eve. We turn the cameras on about one hour before Santa enters a country then switch them off after we capture images of him and the Reindeer. We immediately download the images on to our web site for people around the world see. Santa Cams produce both video and still images.

The last system we use is the NORAD jet fighter. Canadian NORAD fighter pilots, flying the CF-18, take off out of Newfoundland to intercept and welcome Santa to North America. Then at numerous locations in Canada other CF-18 fighter pilots escort Santa, while in the United States American NORAD fighter pilots in either the F-15 or F-16 get the thrill of flying with Santa and the famous Reindeer Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner, Blitzen and Rudolph. About a dozen NORAD fighters in Canada and the United States are equipped with Santa Cams.

The tradition began after a Colorado Springs-based Sears Roebuck & Co. store advertisement for children to call Santa on a special "hotline" included an inadvertently misprinted telephone number. Instead of Santa, the phone number put kids through to the CONAD Commander-in-Chief's operations "hotline." The Director of Operations, Colonel Harry Shoup, received the first "Santa" call on Christmas Eve 1955. Realizing what had happened, Colonel Shoup had his staff check radar data to see if there was any indication of Santa making his way south from the North Pole. Indeed there were signs of Santa and children who called were given an update on Santa's position. Thus, the tradition was born.

Deb-a-day returns, but dormant since Nov 22


Eric Railine noted at "Deb-A-Day" is back at a new location! that David Moreno Garza resurrected the idea of noting a Debian package a day via the debaday - One daily Debian package blog. The former site's last entry was in November, 2004. The new site's latest entry is xmovie, on November 22, 2005. I don't see permalinks to the individual entries.

Honest car repairs in Raleigh: J & J Automotive on Capital Blvd


My '94 Chevy Corsica (110K+ miles) needed front end work recently, and a co-worker recommended Robert Alvarez's J & J Automotive (no web site). He did a good job replacing the upper and lower tie rods and one of the strut enclosures (don't know the exact name for that). The price was right.
