GeneBox Update

A Closer Look at NASA's GeneBox Payload, SpaceRef

"This first flight of Genesis is primarily a proof of concept mission for larger inflatable modules. However, it also carries some interesting scientific hardware, which could serve as the basis for future small free flying satellites - often referred to as smallsats or nanosats. Named "GeneBox", this small payload was developed by NASA Ames Research Center to test out new ways to perform in-flight genomic analysis of living systems. Indeed, much of what is being flown aboard this satellite is cutting edge biotech - the likes of which have yet to fly aboard the International Space Station. Future versions will be even more capable."

Devon Island Drilling Update

Automated Drilling Field Demonstrations Exceed Goals, Go "Naked" in Haughton Crater 2006 DAME Tests

To look for ice or especially organics on Mars, we will need to drill below the oxidized and irradiated surface, probably at least 1-2m. Hardened subsurface ice layers aren't going to be addressed with lightweight scoops on manipulator arms, drills will be needed. But drilling is an art form on Earth, even "automated" offshore oil drilling platforms have control rooms full of people watching and adjusting the drilling.

The Mars Institute's Arthur Clarke Mars Greenhouse on Devon Island now has two webcams available for public viewing. One camera shows a view of the greenhouse and surroundings from the outside and the other shows some of the internal plant growth trays. Images are updated once a day. Click on image to enlarge

    Follow The Methane (and Ethane)

    Cassini Radar Finds Hydrocarbon Lakes on Titan

    "The Cassini spacecraft, using its radar system, has discovered very strong evidence for hydrocarbon lakes on Titan. Dark patches, which resemble terrestrial lakes, seem to be sprinkled all over the high latitudes surrounding Titan's north pole. Scientists have speculated that liquid methane or ethane might form lakes on Titan, particularly near the somewhat colder polar regions."

    NASA Mars Picture of the Day: Gullied Recesses

    "This image shows gullies on the wall of a martian south mid-latitude impact crater. The channels in each gully head beneath an eroding overhang of layered rock, providing support for the hypothesis that someif not allmartian gullies result from release of groundwater to the surface."

    Mars Institute HMP Research Station Astrobiology Update 21 July 2006

    Dr. Richard Lveill, Visiting Fellow in astrobiology at the Canadian Space Agency: "The first question I am investigating is did impact-induced hydrothermal systems (i.e. hot springs created by the force of the impact) at Haughton support chemosynthetic microbial ecosystems? The second question I am trying to answer is what is the nature and origin of Mars-like minerals in ancient lake sediments found in the Haughton Crater?"

    Mars Institute HMP Research Station Update for July 19, 2006

    Another busy day at the Haughton-Mars Project Research Station (HMP RS). As we approach the mid-point in the field season, researchers are making significant strides on a number of fronts for their respective projects. Traverses were led to the Trinity Lake region and into the Haughton Impact structure to study geology and biochemistry, while the DAME autonomous drilling team continued to refine their operations and attain new milestones. As reported yesterday, the CSA team working in the Arthur Clarke Mars Greenhouse continued with their ambitious schedule and are continuing to report successes. Construction and upgrades to the HMP RS facility are also proceeding very well.

    "The joint expedition includes a 32-day WHOI research program funded by the U.S. National Science Foundation to the Pacmanus vent sites in the Eastern Manus Basin. The remotely operated vehicle Jason will be used to survey and map the vent areas around an Ocean Drilling Program hole drilled in 2000."

    "We drove a half hour out of town to the first transect site. The teachers separated and went with different scientist to collect samples of the rocks and soil. Our sampling tools consisted of sterile spoons, plastic gloves and zip-lock baggies. The scientists are all passionate about their work here and the teachers are excited to be doing real science along side the scientists. We were still working out the kinks of cooperation and communication. We kept hearing the term "herding cats", which was a good description of the progress of our group."

    Exovegetation

    NAI's Virtual Planetary Laboratory Team have explored the possibility of detecting exovegetation on terrestrial planets orbiting M stars. They estimated the red-shift of this surface feature using leaf optical property spectra with a three photon photosynthetic scheme. The authors have produced a model wherein a pigment-derived surface signature such as exovegetation could be detected, but would be dependent upon the extent of the vegetation on the surface, cloud cover, and viewing angle.
