Balancing Brains
Koyaanisqatsi writes "NASA researchers are learning more about the human brain by studying how astronauts regain their balance upon returning from space. Back home, an astronaut's brain no longer knows how to interpret what the senses tell it. The brain has to adapt to a zero gravity environment in space, then readjust back on Earth. The transition may bring on motion sickness. Ever wonder how your brain would react? (Full Story). Same article is also available via streaming audio or as a downloadable mp3 file." -

NASA Contractor Fraud
Punk Walrus writes "AP New is reporting that NASA has been defrauded dozens of times with things like faulty parts for the International Space Station or even the theft of moon rocks. Just in the last year, NASA contractors and even some of its own employees (more than 50 individuals and nearly three dozen instances) have cost NASA a small chunk out of their $14.8 billion budget. In one case, a NASA contract worker pleaded guilty to accepting $27,000 worth of collect telephone calls from prison inmates, and her company billed the cost to the Hubble Space Telescope program. Remember when Opus on Bloom County wanted to build a satellite Shield of dollar bills around the earth's orbit? Now it doesn't seem so funny anymore." -
Hip Science: Better Bone Implants
ke4roh writes "Space, medicine, and invention often cross paths. In this case, the invention is a new artificial hip. Scientists are researching ways to manufacture strong and porous ceramics with the benefit of microgravity - subtracting the effects of convection and settling from their experiment. In the end, they hope to offer a permanent artificial hip - much more user-friendly than today's models that come unglued and require replacement after only 5-10 years of use. It's just one more way space research helps to make life better on Earth." -
Russians Reveal Early Death of Laika
jonerik writes "Contrary to long-believed Soviet reports that Laika the space dog - the first living animal to be launched into orbit from Earth - lived for a week or so after she was launched into orbit aboard Sputnik 2 in November 1957, CNN is now reporting that Dimitri Malashenkov of the Institute for Biomedical Problems in Moscow has presented a scientific paper at the World Space Congress in Houston, Texas in which he revealed that Laika actually died a few hours after launch due to thermal insulation problems overheating the cabin interior. Sputnik 2 remained in orbit a total of 162 days, before burning up in the atmosphere on April 14, 1958." -
Proposed Next-Generation Space Station
WallytheWalrus writes "This NewScientist.com article discusses the proposed next generation of telescopes and space stations. The concept presented with little fanfare by the NASA Exploration Team (NEXT) consists of placing a space station about 5/6ths of the way to the moon at one of a handful of local Lagrangian Points. This station would act as a springboard for constructing new telescopic mirrors, maintaining the telescopes that use them, and as a haven for future manned exploration missions. If only NEXT's budget was more than $4 million a year...." -

Galileo's Flyby of Almathea
An anonymous reader writes "The spectacular Galileo flybys of Jupiter, Europa and Io are largely credited with the discovery of frozen water ice and some of the earliest examples of non-solar (tidal) heating anywhere in our solar system. For the next 10 days, Galileo scientists are preparing for their next target: probing one of Jupiter's moons, Almathea, at the close-up range of 100 miles. Almathea is one of the most unusual moons in the solar system, because it gives off more heat than it receives from the Sun." -

Fortran 2000 Committee Draft
Richard Maine writes "John Reid, convenor of the ISO Fortran standards comittee, has posted the following announcement to some Fortran-related forums: 'I am pleased to tell you that the draft Fortran 2000 standard is now out for comment. ... The J3 (USA Fortran committee) version, which is identical except for the title page and the headers and footers, is available in ps, pdf, text, or source (latex). This is a very significant milestone for Fortran 2000. It is a major extension of Fortran 95 that has required a significant amount of development work by the J3. ... The abstract of the revision, which lists the major enhancements is appended. I have written an informal description of the new features, which will be published in the next issue of Fortran Forum (about to appear).'"The formal position is that a CD (Committee Draft) Registration and Approval Ballot is in progress. The deadline for comments (from national bodies) is 27 December. Each national body will have its own deadline ahead of 27 December, so be sure to submit your personal comments to your national body well before then. For the USA, they should be sent to Deborah Donovan, email: ddonovan@itic.org. For the UK, they should be sent to David Muxworthy, email: d.muxworthy@ed.ac.uk.

ISO/IEC JTC1/SC22/WG5 N1494
Committee Draft revision of ISO/IEC 1539-1:1997 - Programming Language Fortran - Part 1: Base language
Abstract
Fortran is a computer language for scientific and technical programming that is tailored for efficient run-time execution on a wide variety of processors. It was first standardized in 1966 and the standard has since been revised three times (1978, 1991, 1997). The revision of 1991 was major and those of 1978 and 1997 were relatively minor. This proposed fourth revision is major and has been made following a meeting of ISO/IEC JTC1/SC22/WG5 in 1997 that considered all the requirements of users, as expressed through their national bodies.
The significant enhancements in the 1991 revision were dynamic storage, structures, derived types, pointers, type parameterization, modules, and array language. The main thrust of the 1997 revision was in connection with alignment with HPF (High Performance Fortran).
The major enhancements for this revision are
(1) Derived type enhancements: parameterized derived types, improved control of accessibility, improved structure constructors, and finalizers.
(2) Object oriented programming support: type extension and inheritance, polymorphism, dynamic type allocation, and type-bound procedures.
(3) Data manipulation enhancements: allocatable components, deferred type parameters, VOLATILE attribute, explicit type specification in array constructors, pointer enhancements, extended initialization expressions, and enhanced intrinsic procedures.
(4) Input/output enhancements: asynchronous transfer, stream access, user specified transfer operations for derived types, user specified control of rounding during format conversions, named constants for preconnected units, the flush statement, regularization of keywords, and access to error messages.
(5) Procedure pointers.
(6) Support for IEC 60559 (IEEE 754) exceptions.
(7) Interoperability with the C programming language.
(8) Support for international usage: access to ISO 10646 4-byte characters and choice of decimal or comma in numeric formatted input/output.
(9) Enhanced integration with the host operating system: access to command line arguments, environment variables, and processor error messages.
In addition, there are numerous minor enhancements.
Except in extremely minor ways, this revision is upwards compatible with the current standard, that is, a program that conforms to the present standard will conform to the revised standard.
The enhancements are in response to demands from users and will keep Fortran appropriate for the needs of present-day programmers without losing the vast investment in existing programs.

JPL Begins Commercialization
An anonymous reader writes "JPL has always been concerned with how their work has benefitted society and the Earth as a whole. Everything from developing tools to study what causes El Nino/La Nina to helping find sources of pollution in our environment. In an effort to continue their work while decreasing their burden on NASA's budget, JPL will introduce the JPL Commercialization Center. This means they will begin developing relationships with commercial entities to adapt their technologies for public use. The public benefit is two-fold since licensing fees will help ease NASA and taxpayer burden and life-enchancing technologies will be put into public use." -

NASA Satellite Un-stranded
Ronnie Coote writes "In March, a previous article mentioned that NASA's latest Tracking and Data Relay Satellite (used for communications between Shuttle, Space Station, ground, etc) had been stranded in a low orbit due to fuel leaking from its tanks. Well, thanks to the hard work of Boeing and NASA boffins, it's now reached geostationary orbit and "expected to fulfill its contractually required 15-year service life". More details from Boeing." -
Amateur Rocket Launch a Failure; NASA Debuts Shuttle-cam
Anonymous Coward writes "CNN has posted the story of the failure of the amateur rocket launch that was reported in a previous Slashdot story. 'The launch was spectacular and the rocket was performing as planned. However, the rocket experienced motor failure during the flight and the flight was terminated," said Eric Knight, co-leader of the CSXT mission.' NASA is planning to mount a camera on the external fuel tank and broadcast an October 2nd shuttle launch. -
Aurora Season Begins
MagnetarJones writes "Northern autumn began today at 55 minutes past midnight EDT (Sept. 23rd at 0455 UT), which means 'aurora season' is officially underway. Scientists aren't certain of all the reasons why, but there are more geomagnetic storms during autumn than other times of year. Already this month three such storms have triggered auroras visible as far south as the Carolinas in the United States. Some were so bright they cast shadows!" -
SpinCam: High-Gravity (100G) Camera
An anonymous reader writes "Centrifuge-cameras began exploration of genetic changes at the extremes of high gravity-- in the only animal with a completely sequenced gene library. Students at Harvey Mudd designed the 100G camera, Stanford is doing the gene array and NASA is spinning the 1 millimeter worms that are the model system for how to adapt and survive 100-times your terrestrial weight. Accelerated aging and slowed DNA repair are just two biological consequences of gravity changes. The Japanese (NASDA) are building the space station centrifuge for 2006. What other garden-variety objects can be photographed in that kind of ultra-spindryer?" -
A Shocking Space Movie
MagnetarJones writes "Multiple observations made over several months with the Chandra X-ray Observatory and the Hubble Space Telescope captured the spectacle of matter and antimatter propelled to nearly the speed of light by the Crab pulsar, a rapidly rotating neutron star the size of Manhattan. "Through this movie, the Crab Nebula has come to life," says Jeff Hester of Arizona State University." -

ISS Microgravity Research
Grey-Ghost writes "A while back NASA contracted the Microgravity Research Development and Operations Center (MRDOC) Fluids and Combustion Facility (FCF). This facility is designed to perform about five micro-gravity combustion and/or fluid experiments per year once it goes up (scheduled for sometime in 2004). The project is mostly being developed by the coordinated efforts of Northrop Grumman and Analex but the facility is scheduled to outlast the completion of the currently scheduled fluids and combustion experiments. As someone working on the project, I haven't seen much coverage, but the experiments and technology that could come out of these experiments include molecular biology and/or nanotech construction (LMM), better fuel economy both in space and on Earth (MDCA), and answers to why your Katsup suddenly comes out after copious shaking (fluid shearing)." -

NASA Names Next-Generation Space Telescope
Betelgeuse writes: "The Trek-obsessed people over at NASA have let go of the somewhat unwieldy name for the next major space-based optical observatory (formerly the 'Next Generation Space Telescope'). The space-based observatory will be known as the James Webb Space Telescope, named after James E. Webb, NASA's second administrator. While Webb is best known for leading Apollo and a series of lunar exploration programs that landed the first humans on the Moon, he also initiated a vigorous space science program, responsible for more than 75 launches during his tenure, including America's first interplanetary explorers. In addition, they've also announced the builder: TRW, Redondo Beach, CA. The press release is here." -
Discovering Extrasolar Planets in Your Backyard
RobertFisher writes: "As professional astronomers have continuned to build ever more powerful telescopes, the role of amateur astronomers has diminished substantially, mainly to monitoring variable stars and discovering comets. Now a group of professional astronomers at UC Santa Cruz are beginning an exciting new project, to discover extrasolar planets using a network of amateur astronomers who will monitor candidate stars for transits of extrasolar planets. From their website : '...the past several years have seen the introduction of highly affordable small telescopes equipped with sensitive and stable CCD (charge coupled device) detectors, and controlled by laptop computers. Thousands of amateur astronomers already own observatories which, when properly configured, are capable of reliably detecting the periodic dimming which occurs when a close-in giant planet passes in front of the parent star as seen from Earth.'" -
Houston, We Have a Software Problem
An anonymous reader writes "The computer system that launches the Space Shuttle is an old, but important, computer system. It is built from mid 70's technology and features SSI chips like 7400's...which are getting hard to find. It has 64k of memory and no room to repair any software bugs. NASA started the CLCS project in 1996 which uses state of the art computer languages, OO methodologies, and hardware. Everything that you could actually hire people off the street for. However, NASA is in a budget crunch with the Space Station cost overruns. It is looking to trim costs to keep the Space Station going. There are stories about CLCS getting cancelled here and these guys say its already cancelled." -
HESS Gamma-Ray Telescope Inaugurated This Week
Grandroyill writes "Most ground-based telescopes with lenses and mirrors are hindered by the Earth's nurturing, protective atmosphere that blurs images and scatters and absorbs light. But this telescope...actually requires the atmosphere to operate. As the gamma rays impact the upper atmosphere they produce air showers of high-energy particles. Adorned with 382 separate mirrors each 60 centimeters in diameter and equipped with a fast camera, the telescope records in detail the brief flashes of optical light, called Cherenkov light, created by the air shower particles. Great pic too!" Beautiful telescope. Kudos to the engineers. -
World's Largest Airborne Telescope Delivered
Thurog writes "SOFIA, the Stratospheric Observatory for Infrared Astronomy, has received the telescope built in Germany by the German Space Agency, DLR. SOFIA consists of a Boeing 747SP aircraft modified by L-3 Communications Integrated Systems to accommodate a 2.5 meter reflecting telescope. When on a mission, it will soar through the higher levels of the atmosphere, thereby overcoming the fact that atmospherical humidity filters most of incoming infrared radiation. It's not the first airborne telescope, but so far the most powerful." -
