8.1 Developing Space Experiment Opportunities
Student teams working with the PI have been developing two experiments for flight opportunities on the Space Shuttle. The first is a Student Experiment in Microgravity (SEM) module, which is scheduled for the next opportunity to launch a powered SEM module. The experiment is a cylindrical acoustic resonator containing Styrofoam balls, with ports in the cylinder at the expected nodal planes to inject liquid epoxy resin after the sound field is turned ON. The entire experiment has to be miniaturized, and packaged inside a small container, with total automation including feedback control of the resonant frequency.
The objectives here are
1) to record video of the formation of a solid wall, and its dynamic characteristics in the relatively clean microgravity environment of the Shuttle (expected g-jitter less than 0.01g)
2) to return a solid sample for structural and material analysis of objects formed using acoustically tailored force fields.
Prototype integrated circuit boards are being built for final testing.
The other experiment opportunity is a Getaway Special (GAS) module. Here, a deposit has been paid, and we are on the waiting list but the GAS program is itself facing uncertainty. The payload in this case can be around 80lbs, with a larger resonant chamber. The effort at this point is mainly on design and documentation, to obtain experience with payload development on this scale.

8.4 Media Coverage
1. New Scientist, a well-known British publication, has done two articles over the past 2 years describing first our Acoustic Shaping work (Out of Thin Air, Sep. 2001) and the Tailored Force Fields work (Rubble-Rousing in Space, October 11, 2002).
2. These articles have excited considerable interest, worldwide, showing a very high level of public interest in the prospects for developing business and living environments beyond Earth. Some examples are in Items 3 and 4 below.
3. Josh Magazine, New Delhi. Recently, an article has appeared in Josh, a childrens magazine published in Hindi in New Delhi, describing the Tailored Force Fields work and its relevance to future habitats and economic opportunities in Space.
4. Malayala Manorama, a Kerala (India) Based newspaper, has also presented a full-page Sunday Supplement article on the TFF work.
5. An on going interaction has been developed with the Astronomer community interested in Near-Earth Objects regarding ideas for developing extraterrestrial resources.
6. United Press International, and a Danish science magazine have expressed
strong interest in developing stories related to our work for young audiences.

Radio waves could construct buildings in space 11 October 02 Bennett Daviss
"..Huge buildings could be conjured up in space using nothing more than focused radio waves to push individual components into place. Radio-controlled construction would get around one of the obstacles to colonising space- the need to ferry heavy construction equipment into orbit and suppor tthe people who will operate it... The scale does not daunt NIAC directorRobert Cassanova. "We see the idea as a way to build very large structuresin space economically and with a minimum of manual labour," he says. "If you're able to move materials using waves, you could eliminate the need for large numbers of astronauts and the infrastructure to support them"..."

ForceFields to the Rescue
Posted By: Brian @ 7:00 PM (MST)
There have been quite a few sci-fi books that include or assume large work forces of spacewalkers for building stations and other large structures in microgravity. This is hazardous stuff; nasty momentum events, micrometeorites, cosmic rays, and space debris are all waiting to puncture, pulverize, or poach exposed human bodies (space suits are too flimsy for much more than minimal protection). Robots are expensive, somewhat fragile and slow-moving, and lack versatility. But it may be possible to tune radio waves to match the dimensions of construction components and shove them around and assemble them by remote control. P.S. -- Sounds to me like a good way to clear out all the orbital crud now threatening satellites and launch vehicles.
