Small robots designed by University of Nebraska researchers (see previous post) may allow doctors on Earth to do surgery on patients in space. The tiny, wheeled robots, which are as wide as a lipstick case, can be slipped into small incisions and computer-controlled by surgeons.

Some robots are equipped with cameras and lights and can send back views of affected areas to surgeons. Others have surgical tools attached that can maneuver inside the body. Because several robots can be inserted through one incision, they could reduce the amount and size of cuts needed for surgery.

The robots may be also helpful on battlefields as they could enable surgeons in other places to work on injured soldiers on the front line.

A robot capable of doing biopsies is in the works and another is being designed that can be inserted into a person's stomach via the esophagus.

"We need to design some pretty revolutionary spacesuits if we're really going to realize human exploration of other [planetary] bodies," says Dava Newman, at MIT. Together with her team, she's trying to build the BioSuit, a form-fitting "second skin," designed for lunar and Martian living.

A primary function of a spacesuit is to maintain air pressure in the airless vacuum of space or the sparse atmosphere of Mars. In the late 1960s, Paul Webb created a spacesuit that featured six layers of elastic that pressed the body to mimic pressure. The design was lighter and provided greater range of motion than the current "gas bag." Webb tested the suit and its physiological effects and wrote a report in 1971 that said the idea was viable and safe. But NASA didn't bite.

Newman took up the challenge. The proposed BioSuit will consist of a skintight body suit, a hard torso and backpack for life-support systems and equipment, and a domed helmet.

Newman's team has made several lower-leg prototypes, including one of nylon-spandex, one of elastic wrapped like bandage, and another of pressurized foam painted with layers of urethane.

Ultimately, the BioSuit must maintain fairly constant pressure over the whole body as it moves.

Putting on a BioSuit might feel a bit like squeezing into a wetsuit several sizes too small. The researchers are looking to metals and polymers that expand, contract, or change their properties in response to heat or electricity. Most of these technologies exist, but are too weak or power-hungry to use yet.

Eric Anderson, CEO of Space Adventures, the space tourism firm that arranged Gregory Olsen's voyage has teamed up with Joshua Piven, co-author of "The Worst-Case Scenario Survival Handbook" to write The Space Tourist's Handbook.

The book covers destinations, modes of travel, accommodations, sightseeing, meals and costs.

The packages are rated on three criteria: mission time, travel and training time, and cost, which can range from one dollar sign (symbolizing a trip costing less than $10,000) to five dollar signs (standing for a trip that costs more than $1 million.)

Since the only ship currently offering tourists passage to the International Space Station is the Russian Soyuz, the handbook also includes a helpful list of phonetic Russian phrases such as Olya che-VOH EH-tah KNOHP-ka? ("What does this button do?")

There are also tips and etiquette for everything from sleeping to eating to bathing to using the vacuum toilets (Lesson 1: Make sure there is a tight seal between your body and the toilet seat.)

NASA engineers have tested out a prototype unmanned sailplane that can detect and use rising air thermals to gain altitude. Once it finds a thermal, it turs off its engine and circles to stay within the updraft. NASA hopes to develop techniques for using thermals that could extend the range of unmanned aerial vehicles that often have very limited fuel.

During the tests the 14-foot-wingspan model added 60 minutes to its endurance by autonomous thermal soaring.

"The flights demonstrated a small unmanned vehicle can mimic birds and exploit the free energy that exists in the atmosphere," said NASA aerospace engineer Michael Allen.

Small, portable, unpiloted, long-endurance vehicles could fulfill a number of observation roles including forest fire monitoring, traffic control, search and rescue.

Starting next month, Nissin Food Products will shoot a promotional spot on the International Space Station for Cup Noodle, featuring a sales pitch by a hungry Russian cosmonaut.

The commercial will air in Japan in November as part of Nissin's "Cup Noodle No Border" campaign,.

Space Films will send a high-def camera to the space station aboard a Russian rocket launch Oct. 1 and direct the filming from Russia's Mission Control Center outside Moscow.

If you're looking for extraterrestrial publicity, the agency will be leaving the camera at the space station in the hope of shooting more advertisements.

The National Space Biomedical Research Institute is exploring the concept of a bike-like centrifuge to be used by astronauts for inflight resistance-training exercise.

SpaceCycleI.jpg

The Space Cycle recreates various levels of gravity ranging from Earth gravity to five times Earth’s gravity. The speed of rotation determines the level of gravitational force.

There's two participants: one on a bike and the other on a platform. As one person pedals, the cycle moves in a circular motion around a centralized pole. The motion generates pressure on the rider, forcing him against the seat in a manner similar to the effect of gravity on Earth. On the platform, the other person performs squat exercises.

"Space Cycle is an artificial gravity exercise gym," said Dr. Vincent J. Caiozzo at NSBRI. "The platform can be fitted with a treadmill, bike or any kind of exercise equipment and provides an environment for exercise under normal, Earth-like loading conditions."

Now if the local gym could get one of those, i might consider investing in a membership (to watch the live show.)
