NASA Wants to Track Earth’s Gravity With a Cloud of Floating Atoms in Space

TANCAL, NERDS: NASA builds the first quantum attraction sensor for space

Researchers (JPL) in the NASA’s Jet Propulsion Laboratory, along with several partners, the quantum gravity Pathfield Pathfinder (QGGPF) project. As shown by its name, the QGGPF is an attraction that measures the acceleration of an object is comparable to another nearby object; The difference in the acceleration of objects is in line with gravity moving on each object. When the weight is stronger, objects-aka test masses – fall faster.

The gravity of the earth is not stable – always varies delicate as mass changes around the planet. Geological processes such as tectonic activities, glaciers or suations can make a little nude forces in an area or other in the other. These turns, which are physically scale, are not invisible, not an ultra-sensitive tools of scientists.

These small changes are not only a trade in nature – navigation systems have a natural resource map and a realistic utility for national security. With the right sensors, scientists can use the gravity to “see” those hiding on the surface of the earth. We understand what the weight is aggravating the weight of the weight.

“We can determine the mass of the Himalayas using the atoms,” said Jason Hyon, Chief Technologist for Earth Sciences in JPL, in a NASA release. QGGPF will use rubidium atoms that are definitely from zero, such as more waves than particles to use space.

Where quantum magic comes in: QGGPF uses two cloudy ultra cold atoms – the test masses – compare how fast they fall in comparisons. The faster fall shows a stronger gravity in this place. The distinction between the two clouds explains the scientists who lied to gravity anomalies.

Unlike the gravitic silhombias, which are an elderly gravitational force, QGGPF uses quantum physics to ensure repetition and accuracy. “I can guarantee the atoms, every measurement will be the same,” he said, “Physician Sheng-Wey Chiow. “We are less sensitive to the noise in the environment.”

Quantum Gravity may be 10 times more sensitive to classical attraction sensors, according to NASA release. This means more drastic data, less blind spots and more blind spots and more about what happened in the future in the future and maybe other planets.

The QGGPF has started until the end of a decade and its main task is to prove the technology “Pathfinder” on its name. “No one before,” said JPL Postdoc Ben Stray, in the same issue. “We should try in space to know what this is really capable of.”

If the QGGPF flies as he flies and fulfills, we can only be on the map with an unprecedented detail of our planet, and we can turn into a gassy and rocky intestine of distant worlds.
