Would you kill for a pair of Air Jordans? Lemon Andersen spins a tale of someone who did, reciting a poem by Reg E. Gaines. These verses taught Lemon that poetry could be about more than self-expression, and could sound like music when given rhythm and infused with the grit of the New York streets around him.

On Dec 3: Stop the 

Internet Coup

Think of all the terrible things governments do to the Internet. The US destroyed Megaupload, Russia jailed activists over a YouTube video, and China monitors Internet users' every move-- even hacking activists outside its borders.

Now imagine if a panel of governments, giant corporations, and dictatorships had absolute power over the entire Internet, deciding in secret what you can see & do online.

When the ITU meets December 3rd, they'll decide on this.

Only a global outcry can stop it.

NASA Rover Finds Clues to Changes in Mars' Atmosphere

PASADENA, Calif. -- NASA's car-sized rover, Curiosity, has taken significant steps toward understanding how Mars may have lost much of its original atmosphere.

Learning what happened to the Martian atmosphere will help scientists assess whether the planet ever was habitable. The present atmosphere of Mars is 100 times thinner than Earth's.

A set of instruments aboard the rover has ingested and analyzed samples of the atmosphere collected near the "Rocknest" site in Gale Crater where the rover is stopped for research. Findings from the Sample Analysis at Mars (SAM) instruments suggest that loss of a fraction of the atmosphere, resulting from a physical process favoring retention of heavier isotopes of certain elements, has been a significant factor in the evolution of the planet. Isotopes are variants of the same element with different atomic weights.
Initial SAM results show an increase of five percent in heavier isotopes of carbon in the atmospheric carbon dioxide compared to estimates of the isotopic ratios present when Mars formed. These enriched ratios of heavier isotopes to lighter ones suggest the top of the atmosphere may have been lost to interplanetary space. Losses at the top of the atmosphere would deplete lighter isotopes. Isotopes of argon also show enrichment of the heavy isotope, matching previous estimates of atmosphere composition derived from studies of Martian meteorites on Earth.

This picture shows a lab demonstration of the measurement chamber inside the Tunable Laser Spectrometer, an instrument that is part of the Sample Analysis at Mars investigation on NASA's Curiosity rover.

Scientists theorize that in Mars' distant past its environment may have been quite different, with persistent water and a thicker atmosphere. NASA's Mars Atmosphere and Volatile Evolution, or MAVEN, mission will investigate possible losses from the upper atmosphere when it arrives at Mars in 2014.
With these initial sniffs of Martian atmosphere, SAM also made the most sensitive measurements ever to search for methane gas on Mars. Preliminary results reveal little to no methane. Methane is of interest as a simple precursor chemical for life. On Earth, it can be produced by either biological or non-biological processes.

Methane has been difficult to detect from Earth or the current generation of Mars orbiters because the gas exists on Mars only in traces, if at all. The Tunable Laser Spectrometer (TLS) in SAM provides the first search conducted within the Martian atmosphere for this molecule. The initial SAM measurements place an upper limit of just a few parts methane per billion parts of Martian atmosphere, by volume, with enough uncertainty that the amount could be zero.

"Methane is clearly not an abundant gas at the Gale Crater site, if it is there at all. At this point in the mission we're just excited to be searching for it," said SAM TLS lead Chris Webster of NASA's Jet Propulsion Laboratory in Pasadena, Calif. "While we determine upper limits on low values, atmospheric variability in the Martian atmosphere could yet hold surprises for us."
In Curiosity's first three months on Mars, SAM has analyzed atmosphere samples with two laboratory methods. One is a mass spectrometer investigating the full range of atmospheric gases. The other, TLS, has focused on carbon dioxide and methane. During its two-year prime mission, the rover also will use an instrument called a gas chromatograph that separates and identifies gases. The instrument also will analyze samples of soil and rock, as well as more atmosphere samples.
"With these first atmospheric measurements we already can see the power of having a complex chemical laboratory like SAM on the surface of Mars," said SAM Principal Investigator Paul Mahaffy of NASA's Goddard Space Flight Center in Greenbelt, Md. "Both atmospheric and solid sample analyses are crucial for understanding Mars' habitability."

SAM is set to analyze its first solid sample in the coming weeks, beginning the search for organic compounds in the rocks and soils of Gale Crater. Analyzing water-bearing minerals and searching for and analyzing carbonates are high priorities for upcoming SAM solid sample analyses.
Researchers are using Curiosity's 10 instruments to investigate whether areas in Gale Crater ever offered environmental conditions favorable for microbial life. JPL, a division of the California Institute of Technology in Pasadena, manages the project for NASA's Science Mission Directorate, Washington, and built Curiosity. The SAM instrument was developed at Goddard with instrument contributions from Goddard, JPL and the University of Paris in France.

Curiosity Lands on Mars

Sun, 05 Aug 2012 11:32:54 PM GMT-0600

NASA's Curiosity rover has landed on Mars! Its descent-stage retrorockets fired, guiding it to the surface. Nylon cords lowered the rover to the ground in the "sky crane" maneuver. When the spacecraft sensed touchdown, the connecting cords were severed, and the descent stage flew out of the way. The time of day at the landing site is mid-afternoon -- about 3 p.m. local Mars time at Gale Crater. The time at JPL's mission control is about 10:31 p.m. Aug. 5 PDT (early morning EDT).

Mars Tugging on Approaching NASA Rover Curiosity

Mars Tugging on Approaching NASA Rover Curiosity

Cruise Vehicles (Artist Concept)

PASADENA, Calif. - The gravitational tug of Mars is now pulling NASA's car-size geochemistry laboratory, Curiosity, in for a suspenseful landing in less than 40 hours.

"After flying more than eight months and 350 million miles since launch, the Mars Science Laboratory spacecraft is now right on target to fly through the eye of the needle that is our target at the top of the Mars atmosphere," said Mission Manager Arthur Amador of NASA's Jet Propulsion Laboratory, Pasadena, Calif.

The spacecraft is healthy and on course for delivering the mission's Curiosity rover close to a Martian mountain at 10:31 p.m. Sunday, Aug. 5 PDT (1:31 a.m. Monday, Aug. 6 EDT). That's the time a signal confirming safe landing could reach Earth, give or take about a minute for the spacecraft's adjustments to sense changeable atmospheric conditions.

The only way a safe-landing confirmation can arrive during that first opportunity is via a relay by NASA's Mars Odyssey orbiter. Curiosity will not be communicating directly with Earth as it lands, because Earth will set beneath the Martian horizon from Curiosity's perspective about two minutes before the landing.

"We are expecting Odyssey to relay good news," said Steve Sell of the JPL engineering team that developed and tested the mission's complicated "sky crane" landing system. "That moment has been more than eight years in the making."

A dust storm in southern Mars being monitored by NASA's Mars Reconnaissance Orbiter appears to be dissipating. "Mars is cooperating by providing good weather for landing," said JPL's Ashwin Vasavada, deputy project scientist for Curiosity.

Curiosity was approaching Mars at about 8,000 mph (about 3,600 meters per second) Saturday morning. By the time the spacecraft hits the top of Mars' atmosphere, about seven minutes before touchdown, gravity will accelerate it to about 13,200 mph (5,900 meters per second).

NASA plans to use Curiosity to investigate whether the study area has ever offered environmental conditions favorable for microbial life, including chemical ingredients for life.

"In the first few weeks after landing, we will be ramping up science activities gradually as we complete a series of checkouts and we gain practice at operating this complex robot in Martian conditions," said JPL's Richard Cook, deputy project manager for Curiosity.

The first Mars pictures expected from Curiosity are reduced-resolution fisheye black-and-white images received either in the first few minutes after touchdown or more than two hours later. Higher resolution and color images from other cameras could come later in the first week. Plans call for Curiosity to deploy a directional antenna on the first day after landing and raise the camera mast on the second day.

The big hurdle is landing. Under some possible scenarios, Curiosity could land safely, but temporary communication difficulties could delay for hours or even days any confirmation that the rover has survived landing.

The prime mission lasts a full Martian year, which is nearly two Earth years. During that period, researchers plan to drive Curiosity partway up a mountain informally called Mount Sharp. Observations from orbit have identified exposures there of clay and sulfate minerals that formed in wet environments.

The Mars Science Laboratory is a project of NASA's Science Mission Directorate. The mission is managed by JPL, a division of the California Institute of Technology in Pasadena. Its rover, Curiosity, was designed, developed and assembled at JPL. Information about the mission and about ways to participate in challenges of the landing, including a new video game, is available at: http://www.nasa.gov/mars and http://mars.jpl.nasa.gov/msl/ .

Astronomers Spot Rare Arc From Hefty Galaxy Cluster

PASADENA, Calif. -- Seeing is believing, except when you don't believe what you see. Astronomers using NASA's Hubble Space Telescope have found a puzzling arc of light behind an extremely massive cluster of galaxies residing 10 billion light-years away. The galactic grouping, discovered by NASA's Spitzer Space Telescope, was observed as it existed when the universe was roughly a quarter of its current age of 13.7 billion years.

The giant arc is the stretched shape of a more distant galaxy whose light is distorted by the monster cluster's powerful gravity, an effect called gravitational lensing. The trouble is, the arc shouldn't exist.

"When I first saw it, I kept staring at it, thinking it would go away," said study leader Anthony Gonzalez of the University of Florida in Gainesville, whose team includes researchers from NASA's Jet Propulsion Laboratory, Pasadena, Calif. "According to a statistical analysis, arcs should be extremely rare at that distance. At that early epoch, the expectation is that there are not enough galaxies behind the cluster bright enough to be seen, even if they were 'lensed,' or distorted by the cluster. The other problem is that galaxy clusters become less massive the further back in time you go. So it's more difficult to find a cluster with enough mass to be a good lens for gravitationally bending the light from a distant galaxy."

Galaxy clusters are collections of hundreds to thousands of galaxies bound together by gravity. They are the most massive structures in our universe. Astronomers frequently study galaxy clusters to look for faraway, magnified galaxies behind them that would otherwise be too dim to see with telescopes. Many such gravitationally lensed galaxies have been found behind galaxy clusters closer to Earth.

The surprise in this Hubble observation is spotting a galaxy lensed by an extremely distant cluster. Dubbed IDCS J1426.5+3508, the cluster is the most massive found at that epoch, weighing as much as 500 trillion suns. It is 5 to 10 times larger than other clusters found at such an early time in the history of the universe. The team spotted the cluster in a search using NASA's Spitzer Space Telescope in combination with archival optical images taken as part of the National Optical Astronomy Observatory's Deep Wide Field Survey at the Kitt Peak National Observatory, Tucson, Ariz. The combined images allowed them to see the cluster as a grouping of very red galaxies, indicating they are far away.

This unique system constitutes the most distant cluster known to "host" a giant gravitationally lensed arc. Finding this ancient gravitational arc may yield insight into how, during the first moments after the Big Bang, conditions were set up for the growth of hefty clusters in the early universe.

The arc was spotted in optical images of the cluster taken in 2010 by Hubble's Advanced Camera for Surveys. The infrared capabilities of Hubble's Wide Field Camera 3 helped provide a precise distance, confirming it to be one of the farthest clusters yet discovered.

Once the astronomers determined the cluster's distance, they used Hubble, the Combined Array for Research in Millimeter-wave Astronomy (CARMA) radio telescope, and NASA's Chandra X-ray Observatory to independently show that the galactic grouping is extremely massive.

"The chance of finding such a gigantic cluster so early in the universe was less than one percent in the small area we surveyed," said team member Mark Brodwin of the University of Missouri-Kansas City. "It shares an evolutionary path with some of the most massive clusters we see today, including the Coma cluster and the recently discovered El Gordo cluster."

An analysis of the arc revealed that the lensed object is a star-forming galaxy that existed 10 billion to 13 billion years ago. The team hopes to use Hubble again to obtain a more accurate distance to the lensed galaxy.

The team's results are described in three papers, which will appear online today and will be published in the July 10, 2012 issue of The Astrophysical Journal. Gonzalez is the first author on one of the papers; Brodwin, on another; and Adam Stanford of the University of California at Davis, on the third. Daniel Stern and Peter Eisenhardt of JPL are co-authors on all three papers.
