Researchers searching the galaxy for planets that could pass the litmus test of sustaining water-based life must find whether those planets fall in what's known as a habitable zone. New work, led by a team of Penn State researchers, will help scientists in that search.
"Setting up a lunar base could be made much simpler by using a 3D printer to build it from local materials. Industrial partners including renowned architects Foster + Partners have joined with ESA to test the feasibility of 3D printing using lunar soil. "Terrestrial 3D printing technology has produced entire structures," said Laurent Pambaguian, heading the project for ESA. "Our industrial team investigated if it could similarly be employed to build a lunar habitat." Foster + Partners devised a weight-bearing 'catenary' dome design with a cellular structured wall to shield against micrometeoroids and space radiation, incorporating a pressurised inflatable to shelter astronauts. A hollow closed-cell structure - reminiscent of bird bones - provides a good combination of strength and weight." More

6-12th Grade Students, Building 262, Room 180, March 27-28
Since 1994, NASA Ames has hosted an annual Space Settlement Design Contest for 6-12th grade students. Thousands of students and hundreds of teachers from around the world have involved themselves in space settlement, some devoting months of intense effort. Prize winners now find themselves at Harvard, Stanford, MIT and other top universities and at least one flew a zero-gravity experiment for the European Space Agency (ESA). Contestants work at home and send their entries to Ames each March. Extensive reference materials are supplied on the web. All entries are judged in a two-day period by a panel of NASA and contractor personnel. Judges commit to one hour or more anytime on Wednesday and/or Thursday, March 27-28, between 10:30 a.m. and 7 p.m. Judging will be in Building 262, Room 180. No experience or specific technical expertise are needed and it is a lot of fun (less expert judges can evaluate entries from the younger students). Contest details are at http://settlement.arc.nasa.gov/Contest/

"NASA engineer Dan Dietrich and a team of scientists at Glenn developed the Portable Unit for Metabolic Analysis (PUMA) to monitor the oxygen consumption and carbon dioxide production rates of astronauts exercising during long missions. The portable unit was designed to give the crew the ability to move around the spacecraft without being tethered to a large immovable unit. PUMA measures six components to evaluate metabolic function: oxygen and carbon dioxide partial pressure, volume flow rate, heart rate, and gas pressure and temperature. From those measurements, PUMA can compute the oxygen uptake, carbon dioxide output and minute ventilation (average expired gas flow rate). A small, embedded computer takes readings of each sensor and relays the data wirelessly to a remote computer via Bluetooth." More

"Imagine a young engineer examining an artifact from the Apollo era that helped send people on humankind's first venture to another world. The engineer has seen diagrams of the rocket engine. She has even viewed old videos of the immense tower-like Saturn V rocket launching to the moon. Like any curious explorer, she wants to see how it works for herself. She wonders if this old engine still has the "juice." Like a car mechanic who investigates an engine of a beloved antique automobile, she takes apart the engine piece by piece and refurbishes it. This is exactly what a small team of young NASA engineers did. The engineers, who have been trained in fields from rocket propulsion to materials science, took apart and refurbished parts from Saturn V F-1 engines--the most powerful American rocket engines ever built. Why resurrect an Apollo-era rocket engine? The answer is simple: to mine the secrets of the F-1 -- an engine that last flew before these engineers were born -- and use it as inspiration for creating new advanced, affordable propulsion systems."

"Welcome to Planet Four, a citizen science project designed to help planetary scientists identify and measure features on the surface of Mars . . . the likes of which don't exist on Earth. All of the images on this site depict the southern polar region, an area of Mars that we know little about, and the majority of which have never been seen by human eyes before! We need your help to find and mark 'fans' and 'blotches' on the Martian surface. Scientists believe that these features indicate wind direction and speed. By tracking 'fans' and 'blotches' over the course of several Martian years to see how they form, evolve, disappear and reform, we can help planetary scientists better understand Mars' climate. We also hope to find out if these features form in the same spot each year and also learn how they change." More

"NASA's Space Technology Program is looking for visionary advanced concepts. This year's annual call for NASA's Innovative Advanced Concepts Program (NIAC) is seeking proposals for revolutionary concepts with the potential to transform future aerospace missions. Proposed concepts should enable new missions or significantly improve current approaches to achieve aerospace objectives. NIAC studies visionary aerospace architecture, system or mission concepts that are exciting and unexplored, yet credible and executable. The concepts are early in development -- generally 10 years or more from operation. They are chosen based on peer review of the potential impact, technical strength and benefits of the proposed study. "While Goddard or Tsiolkovsky envisioned rockets taking humans to space, the rest of the world focused on the industrial revolution and challenges of the early 20th century," said Michael Gazarik, director of NASA's Space Technology Program at the agency's headquarters in Washington. "These visionaries had radical ideas of space travel and exploration that would take dozens to hundreds of years for maturation, but were worth waiting for. NASA's NIAC seeks proposals from today's visionaries who have futuristic concepts that may transform how we live, work and explore the high frontier." More

NASA's Kepler mission Monday announced the discovery of 461 new planet candidates. Four of the potential new planets are less than twice the size of Earth and orbit in their sun's "habitable zone," the region in the planetary system where liquid water might exist on the surface of a planet.
Volunteers from the Planethunters.org website, part of the Oxford University-led Zooniverse project, have discovered 15 new planet candidates orbiting in the habitable zones of other stars.
"We report the latest Planet Hunter results, including PH2 b, a Jupiter-size (R_PL = 10.12 \pm 0.56 R_E) planet orbiting in the habitable zone of a solar-type star. PH2 b was elevated from candidate status when a series of false positive tests yielded a 99.9% confidence level that transit events detected around the star KIC 12735740 had a planetary origin. Planet Hunter volunteers have also discovered 42 new planet candidates in the Kepler public archive data, of which 33 have at least three transits recorded. Most of these transit candidates have orbital periods longer than 100 days and 20 are potentially located in the habitable zones of their host stars. Nine candidates were detected with only two transit events and the prospective periods are longer than 400 days. The photometric models suggest that these objects have radii that range between Neptune to Jupiter. These detections nearly double the number of gas giant planet candidates orbiting at habitable zone distances. We conducted spectroscopic observations for nine of the brighter targets to improve the stellar parameters and we obtained adaptive optics imaging for four of the stars to search for blended background or foreground stars that could confuse our photometric modeling. We present an iterative analysis method to derive the stellar and planet properties and uncertainties by combining the available spectroscopic parameters, stellar evolution models, and transiting light curve parameters, weighted by the measurement errors. Planet Hunters is a citizen science project that crowd-sources the assessment of NASA Kepler light curves. The discovery of these 43 planet candidates demonstrates the success of citizen scientists at identifying planet candidates, even in longer period orbits with only two or three transit events." More
