NASA iTech is a collaborative effort to find and foster innovative solutions that aim to solve challenges on Earth and also have the potential to solve some of NASA's challenges agencywide . The top 10 finalists’ presentations are scheduled on Jan. 31 and Feb. 1 at the culmination of the NASA iTech Forum, which will be held at Canon U.S.A., Inc. in Melville, New York. Representatives from NASA, other federal agencies, industry, the investment community, and others from across the U.S. will be ...

Marrow :  U pon wakeup a 53S crewmember collected breath and ambient air samples. With operator assistance , the subject collected blood samples to support the Marrow investigation. The blood samples were processed in the centrifuge and placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).  The Marrow investigation looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow.   Synthetic Bone BioCell Operations:  During yesterday’s scheduled microscope operations for BioCell Habitats A and B, microscope issues inside the Microgravity Science Glovebox (MSG) prevented ground teams from viewing video footage of the growing bone cells from the BioCells. With the deferment of the fixation of BioCell Habitat A, the crew was able to complete one of today’s media exchanges during yesterda...

What is a barycenter? Tweet We say that planets orbit stars, but that’s not the whole truth. Planets and stars actually orbit around their common center of mass. This common center of mass is called the   barycenter . Barycenters also help astronomers search for planets beyond our solar system! What is a center of mass? Every object has a  center of mass . It is the exact center of all the material an object is made of. An object's center of mass is the point at which it can be balanced. Sometimes the center of mass is directly in the center of an object. For example, you can easily find the center of mass of a ruler. Try holding your finger under the middle of a ruler in a few different spots. You'll find a spot where you can balance the whole ruler on just one fingertip. That's the ruler's center of mass. The center of mass is also called the center of gravity. But sometimes the center of mass is  not  in the center of t...

 Elementary Particle Physics group With BALBEER SINGH DANU  gives ANSWER:- "Over the past few decades, particle physicists have developed an elegant theoretical model (the Standard Model) that gives a framework for our current understanding of the fundamental particles and forces of nature. One major ingredient in this model is a hypothetical, ubiquitous quantum field that is supposed to be responsible for giving particles their masses (this field would answer the basic question of why particles have the masses they do--or indeed, why they have any mass at all). This field is called the Higgs field. As a consequence of wave-particle duality, all quantum fields have a fundamental particle associated with them. The particle associated with the Higgs field is called the Higgs boson. "Because the Higgs field would be responsible for mass, the very fact that the fundamental particles do have mass is regarded by many physicists as an indication of the existence of the Higg...
