Methane Confirmed on Mars
Space Exploration - Around the Solar System
Jan 20, 2009 at 03:53 PM

Methane on MarsIn a paper published in Science last week, a team led by Michael J. Mumma of the NASA Goddard Space Flight Center, confirmed the presence of methane gas in the Martian atmosphere.

The gas was first detected using Earth based telescopes in 2003. However, spacecraft based instruments did not completely support these observations. It has taken several years of careful observation to confirm the results.

Methane is the simplest hydrocarbon. It has four hydrogen atoms attached to a single carbon. Sunlight breaks methane down, so its presence in the Martian atmosphere points to it being actively replenished. The gas could be the product of life, or of geochemistry. There is not enough data to decide which.

"We observed and mapped multiple plumes of methane on Mars, one of which released about 19,000 metric tons of methane," co-author Geronimo Villanueva of the Catholic University of America told a Washington press conference. "The plumes were emitted during the warmer seasons, spring and summer, perhaps because ice blocking cracks and fissures vaporized, allowing methane to seep into the Martian air."

The Mars Science Laboratory rover, due for launch in 2011, will have the ability to measure the isotopic composition of the gas. This may shed further light on the origins of the methane on Mars.

Tonights Moon Brightest for 7 Years
Space Exploration - Around the Solar System
Jan 11, 2009 at 05:05 PM

The MoonThe night of Sunday the 11th January 2009 will be the brightest Moon of the year. This full Moon will be only slightly dimmer than the one on 19th December 2008. This will be the last chance to see such a glorious sight for seven years.

The Moon does not follow a circular path around the Earth. It follows a slightly squashed circle, known as an ellipse. At its closest point to the Earth, called the perigee, the Moon is 50,000 kilometres (31,000 miles) nearer to the Earth than when it is at its furthest point, the apogee.

The Moon will be closest to the Earth on the night of Saturday, 10th January, but it will not be a full Moon on that night. The full Moon is on Sunday night. Tonight’s Moon will be 14 percent bigger and 30 percent brighter than typical full Moon.

They Know Your Every Thought!
Life Sciences - Medicine
Jan 02, 2009 at 07:59 PM

New Scientist has reported on a technology is being developed that may eventually allow your dreams and thoughts to be recorded and played back.

resultsYukiyasu Kamitani at ATR Computational Neuroscience Laboratories in Kyoto, Japan is leading the development team. They use a scanner to record brain activity when a subject is shown a group of 10x10 dots. Software "learns" to associate different patterns of brain activity with different patterns.

In a paper published in the journal Neuron, Kamitani showed that by pooling the results from various volunteers it is possible to recreate the word "neuron" from the scans.

Kamitani says that higher quality images should be possible with improved brain scanners. He wants to find out if it is possible to create record images people are imagining rather than seeing.

It may eventually be possible to record dreams. This leads to all kinds of privacy and legal questions. Could such technology be used to eavesdrop on a person’s thoughts? Could your dreams become cause for divorce?

Big Brother is not only watching you, he is reading your mind ad well.

Brian Wang over at Next Big Future has edited Carnival of Space 84. Lots of interesting stuff as ever.

If you found my post "Does Obama Want the Moon?" interesting, you will find some posts looking at the future of US space policy on this carnival.

Sky Ready for 3DTV Broadcasting
Technology - Television
Dec 19, 2008 at 08:00 AM

Satellite Broadcaster BSkyB, has demonstrated its new three-dimensional television (3DTV) system. The new system can broadcast 3DTV into homes using existing high-definition TV infrastructure.

Three-dimensional viewing is on a roll. Games systems are pushing the development of 3D screens. Nvidia's newer graphics cards use Stereo Gaming technology to enhance some of the most popular PC games.

The magic specs were back in the cinema this year with 'Journey to the Centre of the Earth' and 'Beowulf' both doing well at the box office. Other 3D movies such as 'Toys Story 3' and 'Ice Age – Dawn of the Dinosaurs' are due out in 2009.

According to BSkyB 3DTV is not far behind. Sky engineers have so far broadcast sporting events and the TV show Gladiators.

The BSkyB system requires viewers to wear special 3D glasses. Technology allowing viewing of 3D shows without special glasses will be cheap enough to use in the home in five to ten years time.

The system also requires a special television set capable of converting the dual pictures sent over the satellite link, into a 3D display. Mitsubishi launched a 73-inch 3D television receiver in June 2008. Other companies are expected to follow in 2009 with prices in the £2,000 range (US$3000).

Does Obama Want the Moon?
Space Exploration - Plans and Policies
Dec 18, 2008 at 04:30 AM

Reports of a public row between NASA administrator Mike Griffin and Lori Garver, a member of Barack Obama’s transition team, has reignited speculation on the future of NASA’s manned Moon mission.

The Orlando Sentinel reported a "heated" 40-minute conversation between a "red-faced" Griffin and Garver at a book-publication party at NASA headquarters last week According to witnesses Griffin demanded to speak directly to Obama.

President Elect Obama has sent teams to every government agency in order to ensure smooth transition between administrations. Their job is to dig through budgets and plans to find anything that may cause problems for the incoming administration. The Bush White House has ordered full cooperation.

Griffin appears to consider this a personal insult. Witnesses to the "animated conversation" reported Garver as saying, "Mike, I don’t understand what the problem is. We are just trying to look under the hood."

"If you are looking under the hood, then you are calling me a liar," Griffin replied. "Because it means you don’t trust what I say is under the hood."

Griffon Worried

Griffin was appointed by President Bush four years ago to lead NASA in the efforts for a return Moon shot by 2020 and then on to Mars. He has overseen the selection of Constellation, with its NASA-designed Ares I rocket and Orion capsule for the job. Griffin would like to stay on under the new administration, "under the right circumstances."

Budgetary problems and technical issues with Constellation have been the subject of the transition team's scrutiny. They have asked NASA how much could be saved by cancelling the Area I rocket. They have also asked about accelerating the program. The cancellation question has obviously worried Griffin.

The Orlando Sentinel also reports Griffin is orchestrating a campaign to defend Constellation. It says Griffin is:

"...scripting NASA employees and civilian contractors on what they can tell the transition team and has warned aerospace executives not to criticize the agency’s moon program."

NASA's Chief of Strategic Communications, Chris Shank denied there was an argument or that Griffin is trying to keep information from the Garver's team. He denied that Griffin is seeking a meeting with Obama.

He did acknowledge that Griffin felt the team lack the expertise to assess some of the information they have been given. Griffin, an engineer, has said the Garver is "not qualified" to make decisions on NASA’s rocketry program.

Garver has refused to comment, but people close to her say she has confirmed "unpleasant" exchanges with Griffin and other NASA officials. Garver recently told a Washington meeting of aerospace representatives, "there will be change" to NASA policy. She hinted that there would be a new administrator soon.

Obama's Shifting Position

The situation is exasperated by Barack Obama’s lukewarm support for the Moon shot during his election campaign. His position early in the primaries was to see more NASA spending on education at the expense of the Moon landings. He shifted several times during the campaign.

Obama only came out firmly in support of the new Moon shot when if became obvious that the loss of jobs in important battleground states such as Florida could derail his bid for the Presidency.

However, these pledges were made when the federal budgetary considerations was very different from those today. It would not be hard to find justification for cutting NASA's budget.
