NASA’s Phoenix Lander Has an Oven Full of Martian Soil

And this is the resulting divot::i-a8a865e8ca82020aad53afe123537e22-SoilSample.jpgNASA’s Phoenix Mars Lander’s Surface Stereo Imager took this image on Sol 14 (June 8, 2008), the 14th Martian day after landing. It shows two trenches dug by Phoenix’s Robotic Arm.Soil from the right trench, informally called “Baby Bear,” was delivered to Phoenix’s Thermal and Evolved-Gas Analyzer, or TEGA, on Sol 12 (June 6). The following several sols included repeated attempts to shake the screen over TEGA’s oven number 4 to get fine soil particles through the screen and into the oven for analysis.The trench on the left is informally called “Dodo” and was dug as a test.Each of the trenches is about 9 centimeters (3 inches) wide. This view is presented in approximately true color by combining separate exposures taken through different filters of the Surface Stereo Imager.The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA’s Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.Image credit: NASA/JPL-Caltech/University of Arizona/Texas A&M UniversityMore details in the following press release: Continue reading NASA’s Phoenix Lander Has an Oven Full of Martian Soil

Interesting Behavior by a Bald Eagle

The following is a description supplied by Amanda of an event she observed two weekends back at The Lake in North/Central Minnesota:

There appeared to be an animal acting strangely on the surface of the water. On further inspection, it turned out to be a bald eagle moving across the surface using its wings like oars. This went on for at least a minute or two. Eventually, the eagle dragged itself in a similar manner onto shore where it stood around for a while, and shortly thereafter made its way up the slope by several feet. Closer inspection with binoculars indicated that the eagle was now eating a fish (probably).It appears that the eagle had grabbed a fish with its talons, but the fish was too big to lift up out of the water. So the bird crawled across the water with the fish in tow. Probably.

Technology Tools

Participate in Sourceforge.net’s 2008 Community Choice Awards. Sourceforge, along with Freshmeat, is a central repository for OpenSource community driven software projects. When installing software on your Linux box, you are better off using the built in software for installation and not downloading stuff from Sourceforge or Freshmeat, until you know what you are doing. But these are great sites to browse and/or search for software you need. Or want.Here’s a few other software related tidbits: Continue reading Technology Tools

Cooperating Robofish Set To Take Over Oceans, Lakes

In the world of underwater robots, this is a team of pioneers. While most ocean robots require periodic communication with scientist or satellite intermediaries to share information, these can work cooperatively communicating only with each other.Over the past five years Kristi Morgansen, a UW assistant professor of aeronautics and astronautics, has built three Robofish that communicate with one another underwater. Recently at the International Federation of Automatic Control’s Workshop on Navigation, Guidance and Control of Underwater Vehicles, she presented results showing that the robots had successfully completed their first major test. The robots were programmed to either all swim in one direction or all swim in different directions, basic tasks that can provide the building blocks for coordinated group movement. This success in indoor test tanks will eventually provide the basis for ocean-going systems to better explore remote ocean environments.”Underwater robots don’t need oxygen. The only reason they come up to the surface right now is for communication,” Morgansen said.Her robots would not need to come to the surface until their task was complete. They could cooperatively track moving targets underwater, such as groups of whales or spreading plumes of pollution, or explore caves, go underneath ice-covered waters, or into) dangerous environments where surfacing might not be possible. Schools of robots would be able to work together to do things that one could not do alone, such as tracking large herds of animals or mapping expanses of pollution that can grow and change shape.

New Global Warming Film by Randy Olson

The film we’ve all been waiting for … Randy Olson (of Flock of Dodos fame) has produced a new film called Sizzle. In the film Olson uses the approach he used in Dodos to address the global warming issue. I have not seen the film but hope to review it soon.Mean time, here’s the press release in full: Continue reading New Global Warming Film by Randy Olson

Obama Likes Edward’s Heath Care

Check this out:

Obama’s speech in Raleigh launching his economy tour is underway, and towards the end, during a discussion of health care, he drops a surprise aside that wasn’t in the speech’s prepared remarks:

“By the way, I’m going to be partnering with Elizabeth Edwards, we’re going to be figuring all this out.”

[Anybody know where I got this? It just was sitting there open on my computer … I’d like to give a ‘hat tip’ …. Maybe Obama has been poking around in my basement again….] Continue reading Obama Likes Edward’s Heath Care

How to be more keyboardy

Being more keyboardy is good. The mouse is good, too. But if you can do more things with the keyboard, those things will usually happen faster and with less mucking around. Also, it is very, very cool to sit there and go “tap tap tap” and have stuff happen on the screen without the mouse. Like in that Star Trek where Scott was forced to use a Mac Classic to design Invisible Aluminum. First he tried to use the mouse as a microphone to communicate with the computer. When that didn’t work, he just went after the keyboard and tap-tap-tap had a design for Invisible Aluminum ready to go. To put whales in.Since most of your time is spent using a web browser, and the main web browser you use is Firefox, I thought I’d pass on a few keyboardy shortcuts. Keep in mind, however, that many keyboard commands are used in common system wide for many different programs, like the first three I’ll mention … they work, in one way or another, in all programs that also use a mouse. Most of the time. Continue reading How to be more keyboardy

Microsoft Attempts to Patent the Very Essence of Humanity

What? Consider this Abstract from the patent:

A software design process includes three elements–an object/component driven element, a situation/scenario driven element, and an arbitrator/communicator element that is logically interposed and serves as an intermediary between the object/component driven and the situation/scenario driven elements. Through an iterative communication process overseen by the arbitrator/communicator, software design can take place and be measured against a metric. The communication process overseen and implemented by the arbitrator/communicator can allow ideas and developments provided by one element to be translated into a format that the other element understands. Once the metric has been achieved, the design process can be terminated.

New Development with Reiser

Hans Reiser developed a file system a while back, for LInux computers (but in theory useful for other systems as well) which is probably the best file system out there. File systems vary in how good they are at handling very large vs. many small files, with something of a trade off between the two. File systems can be super duper fast or very very secure, but there is a trade off between the two. And so on. The Reiser File System addresses these trade offs better than other systems, at least, so many think. This is an open source file systems.There is one small problem: Continue reading New Development with Reiser
