Remote Sensing for Farmers and Flood Watching

The Applied Sciences Directorate, part of NASA's Science Mission Directorate, makes use of the Agency's remote-sensing capabilities to acquire detailed information about our home planet. It uses this information for a variety of purposes, ranging from increasing agricultural efficiency to protecting homeland security. Sensors fly over areas of interest to

Water and Air Measures That Make PureSense

Each day, we read about mounting global concerns regarding the ability to sustain supplies of clean water and to reduce air contamination. With water and air serving as life's most vital elements, it is important to know when these environmental necessities may be contaminated, in order to eliminate exposure immediately.

Harnessing the Power of the Sun

The Environmental Research Aircraft and Sensor Technology (ERAST) Alliance was created in 1994 and operated for 9 years as a NASA-sponsored coalition of 28 members from small companies, government, universities, and nonprofit organizations. ERAST's goal was to foster development of remotely piloted aircraft technology for scientific, humanitarian, and commercial purposes.

Valiant Zero-Valent Effort Restores Contaminated Grounds

Dense non-aqueous phase liquids (DNAPLs) are chemical compounds that can contaminate soil and groundwater to the point of irreparability. These substances are only slightly soluble in water, and are much denser than water. Because of their solubility, DNAPLs form separate liquid phases in groundwater, and because of their density, DNAPLs

Then Why Do They Call Earth the Blue Planet?

While the most common photographs of Earth taken from space show the planet covered in blue water, NASA has managed to produce detailed color images, using satellite imagery, that show the remarkable variation of colors that actually make up the oceanic surface. An ocean's color is determined by the interaction

Saving Space and Time: The Tractor That Einstein Built

In 1984, NASA initiated the Gravity Probe B (GP-B) program to test two unverified predictions of Albert Einstein's theory of general relativity—hypotheses about the ways space, time, light, and gravity relate to each other. To test these predictions, the Space Agency and researchers at Stanford University developed an experiment that

FLIPPER: Validation for Remote Ocean Imaging

In order to better understand our solar system and the ways it supports life, scientists and researchers at NASA study the planets. Of course, one of the planets on which NASA focuses most of its research is the Blue Planet, Earth, since this is the only one currently known to

Progressive Plant Growing Has Business Blooming

Soil, water, and light. According to prevailing dogma, these are the three main ingredients for growing and maintaining healthy plants. But what if you take soil completely out of the equation and limit the presence of water significantly? Can you still nurture plants in such an environment?
