Kate Greene is on a mission to Hawaii. For the last 65 days, she has lived in a mostly windowless dome on the slopes of Mauna Loa volcano, only venturing outside occasionally — and then through an airlock while dressed in a head-to-toe safety suit. She's part of HI-SEAS, a project aimed at studying the way humans might eat, cook, and stay healthy on a long-term Mars mission.
Greene's adventure will last another 53 days. In this video, she walks you through a typical day in a simulated Martian environment — which involves (surprisingly) P-90x workouts and (unsurprisingly) powdered eggs.

China held its first classroom lecture from its orbiting space module as part of efforts to promote an interest in science and space flight to young people. Astronaut Wang Yaping answered questions live from 330 elementary and middle school students at a Beijing high school from on board the Tiangong-1 lab Thursday morning. BBC News has video

NASA JPL sends word today that image processing lab specialists have assembled a billion-pixel view from the surface of Mars, from NASA's Mars rover Curiosity. The 1.3-billion-pixel image is offered with pan and zoom tools here.
It's the first NASA-produced view from the surface of Mars at this resolution, and is stitched together from close to 900 exposures taken by cameras onboard Curiosity, revealing details of the landscape along the rover's route.
Here's a "manageable" download of the full image. More from the JPL news release, below.

More than 6000 people applied, eight were chosen
. And, for the first time, NASA has an astronaut class with gender parity — four men, and four women.
At the BBC: "New details have emerged about the air crash on 27 March 1968 that killed Yuri Gagarin
- the first man in space."
According to Buzz Aldrin though, "Tang sucks." (NBC News)
I don't know if I can fully define human nature, but I'm pretty sure it includes a prurient and/or practical interest in how one uses the bathroom under strange circumstances. Thus, the various videos you've seen over the years explaining how astronauts use the toilet on board the Space Shuttle and the International Space Station. Until a recent visit to Seattle's Museum of Flight, however, I'd never seen how cosmonauts do their business — an issue with increasingly broad reach, now that Americans and other international space voyagers are being ferried into the heavens aboard Soyuz.
The Soyuz toilet does not look much like the ones on board the Shuttle or the ISS. Those are recognizably toilets, for one thing. The Soyuz sanitary unit is more akin to peeing into a soda bottle in the back seat of the family station wagon — if that soda bottle were hooked up to a vacuum cleaner.
This video — kindly shared with us by The Museum of Flight — was filmed in 2009 by NASA astronaut Michael Barratt. It features the urination demonstration talents of spaceflight adventurer Charles Simonyi and Russian cosmonaut Gennady Padalka. Please note that this video only demonstrates how the "part Number 1" works — and even that really only seems to apply to gentlemen cosmonauts. As best I can tell, women apparently just pee into something akin to a compact diaper or sanitary pad. (Fun!) As for "part Number 2", here is how it was described in a 2007 NASA publication written by James Lee Broyan, Jr.:
For fecal collection, a porous bag is placed in the receptacle. Once defecation is complete, the bag is removed, placed sequentially in three bags, and then placed in a wet trash compartment. Based on personal conversations with АСУ trainers, urine collection is acceptable but fecal use is avoided if at all possible with the crew using diet restrictions and preventive measures prior to flight.
• Read the 2007 NASA publication comparing different space toilet systems. Apparently, part Number 2 has also been used by female cosmonauts to dispose of menstrual waste.
• Read a description on the RuSpace site, which gives a little more detail on part Number 2.

"It will probably be some 50 years before any safe space flight from Earth to another planet and back is made, but there seems now to be very little doubt that the dreams of Roger Bacon in AD 1249 and Albertus Magnus in 1280 have left the realm of Wellsian imaginings and become a practical proposition."
Here's a larger size. Guess they didn't think of Rovers!
Later this month, scientists will start sending the first continuous mass hailing beacon into outer space
— a sort of "Hey, you! Yeah, you! Here we are!" message that researchers hope will attract the attention of any intelligent life that happens to exist in the Universe. They're aiming it at the Gliese 526 system, about 17.6 light years away. It's worth noting that this is different than Gliese 581
, a system you probably remember hearing about from the search for Earth-like planets. The two systems aren't even closely related. The name comes from a 1957 survey
of (relatively) nearby stars.

Do you have ideas about the future of humans in space? The US National Academies' Committee on Human Spaceflight is seeking short papers from individual and groups with a vision for the future of human spaceflight.
In developing their papers, respondents are asked to carefully consider the following broad questions.
What are the important benefits provided to the United States and other countries by human spaceflight endeavors?
What are the greatest challenges to sustaining a U.S. government program in human spaceflight?
What are the ramifications and what would the nation and world lose if the United States terminated NASA's human spaceflight program?
"Submitting an Input Paper to the Committee on Human Spaceflight
Y'know "Astronaut Ice Cream
" that's a favorite at science museum gift shops everywhere? I shouldn't be surprised, but astronauts don't eat the stuff. Freeze-dried ice cream was on the Apollo 7 menu but apparently the astronauts hated it so much that it never made it on future missions. (The same outfit that makes the Astronaut Ice Cream also sell a Mission Pack Space Food Sampler
filled with other foods that astronauts probably don't eat.) The new issue of Smithsonian magazine examines the space food collection at the National Air and Space Museum, the place where, like many of you I'm sure, I had my first taste of "astronaut ice cream."

A mechanical engineer (awesomely) named Anjan Contractor has won a NASA grant to prototype a 3D printer for food -- specifically pizza. It will lay down layers of food and flavor powder and melt them together; the powders are room-temperature stable for long periods and can be made from relatively abundant, sustainable foodstocks like insects and soylent green. He prototyped the concept with the 3D chocolate printer in the video above, and he holds out hope that food-printing could solve world hunger by allowing billions to feast on low-wastage, low-energy-input, low-carbon-footprint foods that are printed to order.
Contractor's printer is RepRap based, and is open source hardware; he promises to keep the plans open and free.
I suspect that there's a lot of nutritional subtleties lost when you turn food into processed elements that are recombined (in the same way that beta-carotene in carrots is reliably shown to have health benefits, while beta-carotene supplements are far more questionable). But as a form of food processing, it certainly is exciting!
Pizza is an obvious candidate for 3D printing because it can be printed in distinct layers, so it only requires the print head to extrude one substance at a time. Contractor’s “pizza printer” is still at the conceptual stage, and he will begin building it within two weeks. It works by first “printing” a layer of dough, which is baked at the same time it’s printed, by a heated plate at the bottom of the printer. Then it lays down a tomato base, “which is also stored in a powdered form, and then mixed with water and oil,” says Contractor.
Finally, the pizza is topped with the delicious-sounding “protein layer,” which could come from any source, including animals, milk or plants.

NASA released this stunning video of two powerful X-class solar flares erupting off the upper left side of the sun earlier this month. (Background here.) The images come from NASA's Solar Dynamics Observatory (SDO) and from the ESA/NASA Solar Heliospheric Observatory. The music is by Duesseldorf-based ambient composer Lars Leonhard whose track Thunderbolt was featured in an equally-magificient video of the sun's corona captured by the SDO and released earlier this year. Watch that video below. Leonhard's debut album, 1549, inspired by the US Airways flight that famously hit a flock of geese and was ditched in the Hudson River, is available from Forced Exposure.

Tonight, PBS NewsHour science correspondent Miles O'Brien will serve as master of ceremonies in a Kennedy Center gala honoring the life and legacy of astronaut Sally Ride. The tribute will highlight her impact on the space program and her lifelong commitment to promoting youth science literacy.
Her Sally Ride Science organization reached out to girls, encouraging them to pursue careers in the Science, Technology, Engineering and Math (STEM) fields, where a gender gap persists.
At the PBS NewsHour website, read the column Miles wrote immediately following Ride's death in July 2012, 17 months after she was diagnosed with pancreatic cancer.
