Meteor impact trapped ancient swamp plants in glass

The Moment (Panspermia) by Ryan Rosenberg

Kieren Torres Howard of the Meteorite Working Group, and colleagues have discovered organic material in glass created from a meteor impact.

Remnants of an ancient swamp have been found preserved inside glass created during a meteorite strike. The discovery marks the first time that traces of life have been found to survive the heat and pressure of an impact, adding weight to arguments that microbes travelling on space rocks could have seeded the solar system.

Astrobiologists have long suggested that simple life forms could have hitched a ride to Earth inside meteors, or that impacts on early Earth could have sent terrestrial microbes to other worlds on ejected pieces of our planet. We know that rocks kicked up by impacts can travel vast distances. Martian meteorites with soil trapped inside have landed on Earth, and theoretical calculations suggest that meteor strikes on Earth could have had enough energy to send rocks as far away as the moons of Jupiter and Saturn.

New NASA Map Shows Where You Are Most Likely to Die From Air Pollution

Screen Shot 2013-10-30 at 1.38.14 PMVia PlanetSave:

Each year millions of premature deaths world-wide result from various forms of air pollution. According to a new atmospheric pollution model designed by earth scientist Jason West of the University of North Carolina (data from which informs the NASA map shown above), some 2.1 million deaths per year result from just one particular form of atmospheric pollution: fine particulate matter, or PM2.5, which is emitted in car exhaust and smokestack effluent (and other industrial, domestic and natural  sources).

In general, these polluting particles in the atmosphere are referred to as aerosols (a mixture of particulate matter and air). Aerosols can take the form of suspended particulate matter (SPM), respirable suspended particles (RSP), which are particles with a diameter of 10 micrometers (microns) or less, and, the aforementioned fine PM2.5…the ’2.5′ refers to particles of 2.5 microns or less and may include ultrafine particles, and some forms of soot (such as black carbon soot from cooking stoves and biomass burning).

Space Farming: The Final Frontier

VEGGIE1

Vegetable Production System (NASA)

What do you do next when you’ve successfully screwed up the Earth? Screw up Space too! Agricultural science is approaching its next frontier reports Modern Farmer:

Last year, an astronaut named Don Pettit began an unusual writing project on NASA’s website. Called “Diary of a Space Zucchini,” the blog took the perspective of an actual zucchini plant on the International Space Station (ISS). Entries were insightful and strange, poignant and poetic.

“I sprouted, thrust into this world without anyone consulting me,” wrote Pettit in the now-defunct blog. “I am utilitarian, hearty vegetative matter that can thrive under harsh conditions. I am zucchini — and I am in space.”

An unorthodox use of our tax dollars, but before you snicker, consider this: That little plant could be the key to our future. If — as some doomsday scientists predict — we will eventually exhaust the Earth’s livability, space farming will prove vital to the survival of our species.

Censored Space?

Pioneer10-plaque_1200-1024x811When we talk about travelling to the stars, we often talk in terms of technological development and pushing past the current limits bounding the horizons of space science. However, one thing a space-bound race will always have a hard time hurdling are the strictures on their own understanding of themselves and their culture.

Terrestrial earthlings and space travelers must be categorically different entities even if they’re part of the same species. The courage to traverse the stars must mirror the boundlessness of space itself — how can one cross that void without becoming a void and emptying oneself of earthbound prejudices, expectations, superstitions and beliefs? It’s the only way.

When people ask why we’ve never gone back to the Moon or why we’ve never put a man on Mars, tell them to look at the small mindedness that surrounded the Pioneer plaque and then look no further. It turns out that there is more than gravity keeping humanity’s feet on the ground: self-loathing, prudishness, war paranoia and the fear of sex.… Read the rest

Twin Study to Explore Genetic Aspects of Space Health

Twin studies are the Holy Grail of medical research, but in some fields its very rare to find qualifying sets of siblings. Two astronaut twins (imagine the odds!) are giving scientists at the Baylor College of Medicine the opportunity to study the genetic aspects of human health outcomes in outer space.

dn23999-2_300New Scientist:

“We have the best ground control you could dream of,” says Graham Scott of the Baylor College of Medicine in Houston, Texas, who is helping NASA with the experiment. The question of space health is especially timely as several human trips to Mars are currently being discussed.

Last year, Scott Kelly was chosen to take part in the first one-year mission aboard the ISS, double the usual stay, along with Russian cosmonaut Mikhail Kornienko. Then last week NASA announced a twist: his brother Mark will be monitored on Earth throughout.

John Charles, chief scientist of NASA’s human research programme, says the brothers came up with the idea: “I was discussing plans with Scott and he said, ‘how about the twins angle?’ ”

Researchers will have access to blood and saliva samples from both twins taken before, during and after Scott’s trip to the ISS, along with assessments of their vision, sleep patterns and cardiovascular activity.

Curiousity Rover Spots A Lizard On Mars?

lizard on marsYou may be skeptical, but I want to believe in the adorableness of Mars lizards. UFO Sightings Daily weighs in on an image taken recently by the Mars Curiousity Rover:

This odd creature was discovered on Mars by a person in Japan in March. This animal was not the first to be discovered in NASA photos but is in a long line of strange creatures. This one seems to resemble a rodent but also may be a lizard.

With water existing on Mars in small amounts, its possible to find such desert animals wandering around…although very rare mind you. Then again, is NASA placing animals from tiny cyogenic chambers inside the rover onto the surface of Mars to conduct tests?

Former NASA Official Found Dead in Thailand with Rope Around Neck and Genitals

Paul Milford MullerFormer NASA official Paul Milford Muller was found dead in his Thailand home with rope tied around his neck and genitals and surrounded by sex toys and meth. He was also the author of an “erotic thriller”…

Via Daily Mail:

Muller worked for ten years at NASA Jet Propulsion Laboratory at the California Institute of Technology, and served on the Apollo Navigation Team.

He wrote three books, including one called Suicide Inc., which he described as a ‘romantic and erotic thriller’. On the cover of the novel is a picture of a noose.

He grew up in Los Angeles and had a PhD in Physics/Astronomy.

Muller had recently joined Twitter and last posted on April 19.

On his bio on his website he states: ‘I write for personal enjoyment and work diligently to share with others. I respect readers and accept that you are the true judges of what we do.
