The latest budget for NASA for FY 2013 sees the agency’s Mars exploration program taking a huge hit – it will get $318 million less than FY 2012. This funding cut has forced NASA to withdraw from the ExoMars, the joint mission with the European Space Agency designed to culminate with a sample return. Without NASA, ExoMars is left in pieces and ESA is hoping the Russian Space Agency Roscosmos will take NASA’s place. This partnership could be without payoff since neither country has had great luck with Mars, particularly Russia whose missions have been thwarted by the mythical galactic ghoul. NASA’s withdrawal brings other questions to the forefront as well, like whether the agency has lost its way and will it soon lose its prestige in space. My whole article on the subject was published yesterday on Nature’s Soapbox Science Blog. (Left, an artist’s concept of ESA’a Beagle 2 falling through the Martian atmosphere.)
Have you ever stopped to wonder why, during planetarium presentations filled with stunning images from other worlds, there is always a classical music soundtrack? That’s because no one has managed to capture planetary sounds, but not for lack of trying. NASA’s Mars Polar Lander carried a microphone but the spacecraft crashed during its descent in 1999, and a French mission designed to record sound on Mars never flew. NASA’s successful Mars Phoenix Lander carried a microphone, but it failed to return any audio data during its 2008 mission. Simulated sounds, on the other hand, are easier to capture. Adjusting sound waves to reflect the environments on other bodies, we can start to get a sense of what space sounds like. Read the full article on Motherboard.

This week, the James Webb Space Telescope (JSWT) got its brain, or at least the bit responsible for its memory. The first solid-state electronics unit that will store the telescope’s data was delivered from SEAKR Engineer to the telescope’s builder, Northrop Grumman. It’s the same technology that’s inside devices like DVRs, meaning JWST is about to turn into a cosmic TiVo. Read the full article on Discovery News, where I am pleased to say I am a new writer!

NASA’s Lunar Reconnaissance Orbiter keeps finding interesting things on the moon. Last week, LRO’s camera photographed the landing sites of Luna 23 and 24, two Soviet probes that landed in the 1970s. The images have enabled scientists to solve mysteries about these missions, specifically what happened to Luna 23 and why the samples returned by Luna 24 were drastically different than anticipated. It seems these nearly 40-year-old missions are still unfolding. Read the full article on Motherboard. (Left, the Soviet Luna 16 spacecraft. One of many in the long-lasting program.)
On February 13, President Obama unveiled the proposed budget for NASA for the fiscal year 2013: $17.7 billion. That’s $59 million less than FY 2012, and a number that’s expected to remain constant over the next five years. Hardest hit was the Mars program, but this doesn’t necessarily mean the end of exploration on our cosmic neighbour. NASA has had great luck with creative and cost-efficient Martian missions in the past, so it’s possible that the next decade on Mars will be fruitful, it might also look different than anticipated.

The recent cuts to NASA’s budget (after many delays, my article about the budget will be up tomorrow) has effectively killed the agency’s plan of returning Martian samples to Earth within a decade. But could Curiosity, the rover currently en route to Mars, be modified to collect samples? The rover could theoretically become the first stage in a sample return mission, requiring just one follow-up mission to collect and return the samples. That is, if everything works perfectly. Check out the full article on Motherboard. (Left, an artist’s impression of the rover Curiosity on Mars. It is about the size of a Mini Cooper.)
Each of the Mercury missions had a name followed by the number 7. Alan Shepard flew Freedom 7, Gus Grissom in Liberty Bell 7, John Glenn aboard Friendship 7 (pictured), Scott Carpenter in Aurora 7, Wally Schirra flew Sigma 7, and Gordon Cooper aboard Faith 7. Deke Slayton never flew because of a heart condition, but had he flown his mission would have been Delta 7.
So, what’s with all the ‘7’s? Continue reading “Vintage Space Fun Fact: The Mercury ‘7’s”
