NASA thanks Sun Microsystems for their support in the development of World Wind Java. This generous support has led to the very artful and exemplary use of the Java OpenGL API. The possibilities for portable, high-performance 3D graphics rendering are now wide open.
The dream has always been code once, run anywhere. NASA and Sun are helping to make that dream a readily accessible 3D reality, even if it is a virtual one!
Open source technology, when well applied, spurs innovation. This infinite room for innovation also provides for absolute security when this technology is used internally. NASA World Wind visualization technology also provides for proprietary use by business and government, while both will forever benefit from evolution of the code base by Java developers everywhere.
NASA has, as do many of us, an extraordinary wealth of data. For NASA this can be measured in terabytes a day, be it from satellites orbiting Earth or telescopes peering into deep space. NASA World Wind visualization technology can readily deliver that geospatial data in the most compelling and accessible manner possible.
The power to innovate with this technology is now in your hands. You are free to build into this NASA World Wind Java 3D visualization technology, whatever you think it needs. And you are free to extend or embed the component architecture to your wildest dreams, for business or pleasure, for research or education, but always for compelling information exchange about this world of ours.
NASA has always spurred innovation. Working together with Sun Microsystems, our industry partner in this enterprise, we are creating a world full of opportunity.

Nanotechnology
Nanotechnology could clean up the hydrogen car's dirty little secret
Back in January, when the U.S. president announced his hydrogen fuel initiative and proposed to spend a total of $1.7 billion over the next five years to develop hydrogen-powered fuel cells, hydrogen infrastructure and advanced automotive technologies, he said that it will be practical and cost-effective for large numbers of Americans to choose to use clean, hydrogen fuel cell vehicles by 2020. According to the U.S. Department of Energy's (DOE) Hydrogen Program, the government's goal is to achieve "technology readiness" by around 2015 in order to allow industry to make decisions on commercialization by then. That's only eight years to go. Given where the technology is today, this goal seems very ambitious, to say the least. Nanotechnology could help speed up the journey to the hydrogen society, but it will take some sensational breakthroughs on the way. The three key areas for the vehicles (we will not touch on the infrastructure issues here) are clean - the emphasis is on clean - hydrogen production, hydrogen storage, and the fuel cell itself. We'll take a look at how nanotechnology will play a role in these areas.
Nanotechnology's benefits for disabled people
Following up on yesterday's Nanowerk Spotlight on nanobionics, today we'll look at bionics and other nanotechnology applications that could benefit disabled people. A range of applications and products with a combination of nanotechnology, biotechnology, and information technology are under development to directly improve the lives of people with severe injuries or medical conditions. Solutions range from better implants and prosthetics to brain-machine interfaces and they already are in the early stages of development and have working prototypes. While these are technical solutions to medical issues, and also a potential path towards transhumanist dreams, there is a number of social issues surrounding them that are rarely discussed. For instance, some 180 million young people between the ages of 10-24 live with a physical, sensory, intellectual or mental health disability significant enough to make a difference in their daily lives. The vast majority of these young people, some 150 million (80%) live in the developing world. They have limited access to education, employment and basic health care, and generally experience profound economic and social exclusion. The question needs to be asked whether the nano- and biotechnologies discussed to help the developing world are designed in a way to take into account the specific needs and realities of disabled people. Even if they did - and they do not - the next question is whether all these wonderful new technologies are really affordable for developing countries, or in other words: who pays for them? And finally, does the right social framework exist to take advantage of them?
Nanobionics - where the boundaries between electronics and biology become fuzzy
In case you are not old enough to remember the TV series The Six Million Dollar Man during the 1970s, the show was about an astronaut, Steve Austin, who got severely injured during a crash and became a guinea pig for bionics experiments by the CIA. In an operation that cost six million dollars, his right arm, both legs and the left eye are replaced by bionic (cybernetic) implants that vastly enhanced his strength, speed and vision. Never mind Hollywood, though, but bionics - a word formed from biology and electronics - has become a serious research field. In particular the development of artificial muscles is progressing rapidly. Nature's solution to producing fast contracting muscles is to use nanotechnology. The challenge for scientists is to mimic the intricacy of natural muscle in their artificial-muscle systems. As material scientists and engineers delve into the nanodomain, the boundaries between electronics and biology become fuzzy and this is exactly what they want: a seamless transition between the hard world of electronics and the soft world of biology.
