Transcranial Doppler (TCD) is a bedside, low-cost, and non-invasive technique able to evaluate cerebral hemodynamics ; the implementation of transcranial color-coded duplex sonography (TCCS) aids in evaluating the brain anatomy...
it can detect problems with blood flow when the heart is pumping faster and harder than usual. The test can be done while walking on a treadmill or riding a stationary bike. Or you may be given a drug to mimic the effects of exercise while in a seated, resting...

Specially-designed high-altitude balloons also are used frequently by NASA to perform near-space experiments. During a meteor shower, a high-altitude balloon can collect cosmic dust emitted by the passing space rocks. Beach ball-sized "smart" balloons have been launched to keep tabs on weather ...
You may have to perform spacewalks to accomplish the mission objectives. This will involve getting into a space suit and going through depressurization procedures in the airlock. When your mission objectives have been accomplished, it will be time to return to Earth. Let's look at this process...
A sonogram is a noninvasive imaging test that has no known complications. Ultrasound waves are thought to be harmless.3 While the energy of the ultrasound waves could potentially irritate or disrupt tissues with prolonged exposure, the computer modulates the power of the sound. Also, a trained ...
Yet Langley continued to explore the LOR concept, modifying it to use an enclosed and pressurizedLunar Excursion Moduleor LEM which could dock with the 3-man Apollo spacecraft, allowing two astronauts to transfer between the two vehicles without having to perform a spacewalk. But once again NASA...
