• Moore's law probably doesn't apply to biology, but if it did, it suggests that life as we know it began before the Earth existed. Genetic complexity as a function of time has been extrapolated backwards, but it's obviously more of an interesting thought experiment than a meaningful biological theory. [url]
• NASA's Curiosity rover has analyzed some martian rock samples to answer the question: "could life have ever been supported on Mars?" The answer seems to be yes, but that still doesn't mean Mars had (or has) any life. [url]
• Do we need to look for alien life that's already amongst us? A shadow biosphere on earth could be an explanation for some mysteries like "desert varnish"... or Occam's razor might start cutting in here. [url]

• Meteorite fragments found in Sri Lanka *might* contain extra-terrestrial fossils -- if you kinda squint and tilt your head, the algae-like fossils support a panspermia theory for the origin of life. This isn't the first time a peer-reviewed journal has published a story like this, and it won't be the last. The real question is when will these papers actually be convincing to skeptics.... [url]
• In 1996, a rock named ALH84001 made a lot more headlines when scientists claimed that it might contain evidence of life from Mars in the form of microfossils. Since then, the ALH84001 debate seems to have settled on the view that those small fossils weren't necessarily created by ET life, and the media hoopla re-affirmed that "extraordinary claims require extraordinary evidence." [url]
• Maybe we'll see evidence of life outside our solar system by looking for evidence of asteroid mining operations around other stars -- if we see unusual amounts of dusty debris, it could mean intelligence life has been exploring for interplanetary resources. It might be hard to determine the difference between natural and unnatural debris, though. [url]
• NASA's Curiosity rover has discovered that Mars once had an environment suitable for life. This is an important find, and it raises questions of why Mars doesn't seem to have ubiquitous life now. [url]

• Mars One is now looking for people willing to become astronauts, train for 8 years, and go on a ONE-WAY trip to Mars (and also be part of this globally-televised mission). The first team to go will be democratically elected from six teams of four astronauts, and the launch is scheduled for September 2022. [url]
• Iran is planning to launch a monkey into space sometime in February 2013. Iran has a goal of sending a human into space by 2020 and putting someone on the moon by 2025. (And Iran has already sent a rat, two turtles and a worm into space.) [url]
• MRI scans of astronauts who spent over a month in space show that long term exposure to microgravity can damage eyeballs and parts of the brain. The problems are similar to having intracranial hypertension -- where the brain experiences pressures that press it against the skull and eye sockets. [url]
• A simulated 520-day mission to Mars found that astronauts may need to keep Earth-like schedules or else they'll have trouble sleeping and possibly acquire some mood disorders. This ground-based study will affect plans for manned Mars missions, and it could also have implications for people who live with disrupted sleep and prolonged exposure to artificial lighting. [url]

• Will Wright, the creator of SimCity, has imagined what the first Mars settlement might look like in 2047. A Martian town with a population of 8,000 inhabitants sounds somewhat unlikely in less than 50 years, but it might happen someday. [url]
• An open source Mars Simulator built in Java has been around since 1998. SimMars was never commercially released, so this open source project was the only game in town -- until the mod for SimCity 4. [url]
• FMARS is a simulated Mars habitat project, located near an impact crater on Devon Island. The Flashline Mars Arctic Research Station was created by the non-profit Mars Society in 2000 -- and it would be cool if they rented it out on AirBnB... [url]

• Last year, Opportunity found some "slam dunk" evidence of water having existed on Mars. There may have been an ancient "wet" Martian surface that was hospitable to our own biology, and Curiosity may find additional geological evidence to support a watery history on Mars. [url]
• NASA also recently tested an inflatable heat shield, capable of withstanding hypersonic speeds of up to Mach 10. The Inflatable Re-entry Vehicle Experiment 3 (IRVE-3) could help designers create spacecraft that can land on Mars without the use of fancy rocket cranes. [url]
• India is planning its own mission to mars in 2013 at an estimated cost of $70-90 million. But India's Department of Science hasn't fully approved a Mars mission with full funding, so these plans could be delayed. [url]

“We spend too much time going through the administrative process to clear videos slapped with needless copyright claims,” says NASA’s Bob Jacobs. “YouTube seems to be missing a ‘common sense’ button to its processes, especially when it involves public domain material paid for by the American taxpayer.”

“There seems to be few consequences for companies that engage in such activities, which often include legitimate news organizations. We do agree that people who make false copyright claims against our material should be held accountable, regardless of their automated systems.”

• Travel agents are already booking seats on Virgin Galactic -- for $200,000 (including a $20,000 upfront deposit). Over 450 passengers have already bought tickets. [url]
• Mars One is aiming for human settlement on our neighboring planet around 2023. It'll be a one-way trip, so plan accordingly. [url]
• The Hermes spacecraft received some Kickstarter funding to build its next test rocket. It's still far from developing a rocket system ready for humans, but it's still cool to see more engineers trying to re-invent space travel. [url]
• Alliant Techsystems (aka ATK), which manufactured the Space Shuttle's booster rockets, is developing a rocket system it calls Liberty. This Liberty rocket system is designed to hold 7 passengers and reach destinations like the International Space Station. [url]

The Hubble is looking at a green gas cloud called Hanny’s Voorwerp. The object was discovered in 2007 by Dutch schoolteacher, Hanny van Arkel. [url]

The Kepler telescope found a solid planet about 40% bigger than Earth. That planet is more than a bit too hot for our biology, but there are at least a few hundred more planets in Kepler's sights. [url]

Mars might have giant caves! Or at least, it has big dark craters of some kind. [url]

Here's a "mysteries of space" timeline. Seriously not drawn to scale... especially a googol years in the future. [url]
