An exercise in homelessness.
I just had a thought: when I was a kid, I spent a lot of time standing in the corner, and now I’m standing on the corner. Some things just make you go hmm.
Well, you’ll be glad to know I didn’t have to buy a flashlight because two sweet ladies each brought me one—one is bigger, so I can use it in my camp, and the other is smaller and will fit in my backpack.
NASA’s Mars Reconnaissance Orbiter discovers evidence that Gullies on Mars are being created by Dry Ice
Written by Guy Webster
Pasadena, CA – Repeated high-resolution observations made by NASA’s Mars Reconnaissance Orbiter (MRO) indicate the gullies on Mars’ surface are primarily formed by the seasonal freezing of carbon dioxide, not liquid water.
The first reports of formative gullies on Mars in 2000 generated excitement and headlines because they suggested the presence of liquid water on the Red Planet, the eroding action of which forms gullies here on Earth.

Washington, D.C. – Scientists analyzing data from NASA’s Cassini mission have firm evidence of an ocean inside Saturn’s largest moon, Titan, which might be as salty as the Earth’s Dead Sea. The findings are published in this week’s edition of the journal Icarus.
“This is an extremely salty ocean by Earth standards,” said the paper’s lead author, Giuseppe Mitri of the University of Nantes in France. “Knowing this may change the way we view this ocean as a possible abode for present-day life, but conditions might have been very different there in the past.”

Pasadena, CA – NASA’s Mars Curiosity rover will complete a Martian year — 687 Earth days — on June 24th, having accomplished the mission’s main goal of determining whether Mars once offered environmental conditions favorable for microbial life.
One of Curiosity’s first major findings after landing on the Red Planet in August 2012 was an ancient riverbed at its landing site. Nearby, at an area known as Yellowknife Bay, the mission met its main goal of determining whether the Martian Gale Crater ever was habitable for simple life forms.

Pasadena, CA – If we had a second Earth, we could experiment with its atmosphere to see how increased levels of greenhouse gases would change it, without the risks that come with performing such an experiment. Since we don’t, scientists use global climate models.
In the virtual Earths of the models, interlocking mathematical equations take the place of our planet’s atmosphere, water, land and ice. Supercomputers do the math that keeps these virtual worlds turning — as many as 100 billion calculations for one modeled year in a typical experiment. Groups that project the future of our planet use input from about 30 such climate models, run by governments and organizations worldwide.
Golden Pond, Ky - Land Between The Lakes National Recreation Area invites the public to join them on a walking tour of the Pisgah Bay Project Area. The tour will begin at the North Welcome Station, rain or shine, at 8:00am on Thursday, May 22nd, 2014. Vehicles will caravan from there to tour areas where similar treatments have been implemented. Interested public are advised to wear walking shoes and bring their own snacks, water, tick repellant, and sunscreen.

Pasadena, CA – NASA’s Cassini spacecraft has captured its first-ever image of the pale blue ice-giant planet Uranus in the distance beyond Saturn’s rings.
The robotic spacecraft briefly turned its gaze away from the ringed beauty of Saturn on April 11th, 2014, to observe the distant planet, which is the seventh planet from the sun.

Pasadena, CA – Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime molds, frogs, elephants, humans and the rest of our planet’s living kingdoms. How did it all begin?
A new study from researchers at NASA’s Jet Propulsion Laboratory in Pasadena, CA, and the Icy Worlds team at NASA’s Astrobiology Institute, based at NASA’s Ames Research Center in Moffett Field, CA, describes how electrical energy naturally produced at the sea floor might have given rise to life.
NASA’s Kepler Space Telescope discovers first Earth size planet orbiting another Star in the “Habitable Zone”
Written by Tony Phillip
Washington, D.C. – Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting in the “habitable zone” of another star. The planet, named “Kepler-186f” orbits an M dwarf, or red dwarf, a class of stars that makes up 70 percent of the stars in the Milky Way galaxy.
The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun.
The “habitable zone” is defined as the range of distances from a star where liquid water might pool on the surface of an orbiting planet.

Pasadena, CA – A new study shows that soybean plants can be redesigned to increase crop yields while requiring less water and helping to offset greenhouse gas warming. The study is the first to demonstrate that a major food crop can be modified to meet multiple goals at the same time.
The study, led by Darren Drewry of NASA’s Jet Propulsion Laboratory, Pasadena, CA, used an advanced vegetation model and high-performance computer optimization techniques.
