Mars’ clay minerals might have been formed by volcanic processes, not standing liquid water as generally believed.

The uncertainty of science: Mars’ clay minerals might have been formed by volcanic processes, not standing liquid water as generally believed, according to a new study.

Data collected by orbiting spacecraft show Mars’ clay minerals may instead trace their origin to water-rich volcanic magma, similar to how clays formed on the Mururoa atoll in French Polynesia and in the Parana basin in Brazil. That process doesn’t need standing bodies of liquid water. “The infrared spectra we got in the lab (on Mururoa clays) using a reflected beam are astonishingly similar to that obtained on Mars by the orbiters,” lead researcher Alain Meunier, with the University of Poitiers in France, wrote in an email to Discovery News. The team also points out that some of the Mars meteorites recovered on Earth do not have a chemistry history that supports standing liquid water.

If correct, this alternative explanation would mean that Mars was not that wet in the past, and would have been far less likely of ever having sustained life.

India’s space agency celebrated its 100th launch today.

The competition heats up: India’s space agency celebrated its 100th launch today.

It is unclear whether the numbers include their failed launches. Regardless, India has a vibrant space program, modeled somewhat after the Russian system, a government space agency focused on gaining commercial market share. Whether that model can successfully compete in the commercial world remains unknown. Russia has had success, but only during a period when they were faced with few competitors. Now that the competition is heating up it is unclear whether Russia’s model will be flexible enough to compete.

What is clear about India, however, is that they are passionate about space exploration. Historically, even the Russian government model has worked when the country using it was the new kid on the block.

The Obama administration will miss the legal deadline — from a law he signed only less than a month ago — to provide details on implementing the required budget cuts under sequestration.

The law is such an inconvenient thing: The Obama administration will miss the legal deadline — set by a law he signed only a month ago — to provide details on implementing the required budget cuts under sequestration.

This is only one data point in a long string of data points that have consistently illustrated how disinterested the Obama administration is in dealing with budget issues and the federal debt. And disinterested might be too kind a word. Incompetent also comes to mind.

The Obama administration has extended the power of the ATF to “seize and administratively forfeit property involved in controlled-substance abuses.”

Theft by government: The Obama administration has extended the power of the ATF to “seize and administratively forfeit property involved in controlled-substance abuses.”

In other words, if the ATF thinks a drug crime has occurred, it now has the right to seize any property involved, without due process. The article gives a particularly pointed example:

Children are refusing to eat the Obama administration’s lower calorie school lunches.

Losing the youth vote: In a boycott that began in Pennsylvania and has now spread to Minnesota, children are refusing to eat the Obama administration’s lower calorie school lunches.

Starting this year, there are strict limits on calories, sodium and meat portions. Whole milk is off the menu altogether, and kids are required to take a fruit or vegetable. As parents with fussy eaters might guess, some student’s aren’t salivating over those options.

In the halls of Rockford High School, a food fight over some simple things — cookies, condiments and milk — has started taking off after seniors Adam Anderson and Zach Guthrie set up a Facebook group encouraging a brown bag boycott. Bags were prepared in advance, bearing messages like, “Where’s the ranch?” and “We want our cookies.” By Thursday, the school served about 150 fewer lunches than it had the day before, and students promise the movement will only continue to grow even though there may be no resolution.

I think it a travesty that modern parents think the federal government should provide their kids lunch. This is the parent’s responsibility, not the government’s.

Sign the LunarCOTS petition.

Do you think the commercial space program led by SpaceX is the fastest and cheapest way for the U.S. to get humans back into low Earth orbit? Then why not do it for missions beyond Earth orbit?

The LunarCOTS petition is a campaign to have NASA subsidize private companies to design and build the United States’ future interplanetary missions rather than have NASA do it in big government programs like SLS. Makes sense to me, and so I signed the petition immediately.

The Mars Reconnaissance Orbiter team today released a set of images showing Curiosity’s recent travel on Mars, as well as some fascinating closeups of the spacecraft’s heat shield, parachute, and descent stage.

A delayed but higher prediction for the solar maximum?

The uncertainty of science: The solar scientists at the Marshall Spaceflight Center today revised upward their prediction for the upcoming peak of the solar maximum, from a sunspot number of 60 to 76, while simultaneously delaying the arrival of their predicted peak from the spring to the fall of 2013.

Since Marshall does not archive its predictions, I am required to keep track of the revisions they make and note them here. Previously I had outlined the changes in this prediction since January 2011. Here is an updated listing:
