The research facility can control the
gravity inside a vacuum chamber that is 60 centimetres in diameter and make the
gravitational pull of the earth “disappear.”
The moon has one-sixth of the Earth’s
gravity, and developing the ability to control it, despite Earth’s omnipresent
gravitational pull, is a significant achievement that can help scientists with
future missions to the moon.
However, because of the small size of the
chamber, it cannot be used to train astronauts. Currently, NASA trains
astronauts for microgravity situations in high-altitude parabolic flights.
The newly built research facility in China
can maintain low-gravity conditions for “as long as you want,” Li Ruilin, a
geotechnical engineer working at the China University of Mining and Technology,
told South China Morning Post. According to Ruilin, the chamber will be filled
with rocks and dust to totally simulate the lunar surface, an experiment that
Ruilin believed is the “first of its kind in the world.”
According to scientists, the facility,
which is built to augment China’s ongoing lunar exploration program, will be used
to extensively test technologies that the scientists plan to send to the moon.
This will help scientists work out
technical vulnerabilities in the expensive equipment and test the durability of
instruments in a simulated lunar environment before the deployment of the
actual missions.
Scientists behind the research say that
they were inspired by a 1997 experiment that used magnets to completely
levitate a frog. According to the original research, most of the ordinary
material including human beings exhibit weak diamagnetism. A diamagnetic
object, according to scientists, is repelled by magnetic fields.
So, if a diamagnetic object is placed under
a strong enough magnetic field, its repulsion can even balance gravity,
levitating the object in the air and staying that way as a result.
The 1997 experiment, conducted by a
Dutch-British Physicist Andre Geim, was awarded the satirical Ig Nobel Prize
2000. Ig Nobel Prize is awarded for unusual scientific achievements.
