Prolific Earth Gravity Satellites End Science Mission
Oct 30, 2017 (JPL)
GRACE made science measurements by precisely measuring the distance between its twin satellites, GRACE-1 and GRACE-2, which required that both spacecraft and th...
Russian scientists have found flaws in popular theories of gravity
Oct 27, 2017 (SPX)
At the moment, according to the authors of the paper, black holes are believed to be existing rather than hypothetical objects. The gravitational-wave signal re...
Supercomputers help Los Alamos team interpret LIGO findings
Oct 25, 2017 (SPX)

Space Station Unit to Study Genetics of Model Organisms
Oct 25, 2017 (SPX)
According to Dr. Scott Shipley, project engineer for Spectrum at NASA's Kennedy Space Center in Florida, what make this system unique is it will allow scientist...
Acoustic gravity waves pinpoint where and when objects hit ocean surface
Oct 24, 2017 (UPI)
Researchers can use the method to identify the precise time and location that an object splashed into the ocean. The technique could be used to locate the entry...
NASA Challenges Students to Design Microgravity Experiments
Oct 24, 2017 (SPX)
Students are asked to design and build objects that sink in water in normal gravity, but will be expelled as far as possible from the water during a free fall f...
