India's moon mission Chandrayaan 2 it is
Planned for launch next month will be NASA's key laser instruments
allows researchers to accurately measure the distance to the moon,
according to US rumbureau officials.
Under Lunar and Planetary Science
Conference held in Texas, USA last week, NASA confirmed at Chandrayaan 2 and
Israeli farmer Beresheet, due to touch down April 11, will carry each one
NASA-owned laser retroreflector arrays.
"We are trying to fill the whole
surface with as many laser reflector arrays as we possibly can get there "
Lori Glaze, acting director of the planetary science department of NASA's science
Mission Directorate was reported as "Space.Com".
Retroreflectors are sophisticated mirrors that reflect
Laser light signals emitted from the ground can help clarify where
the lander is. These signals can be used by the scientists precisely
calculate the moon's distance from the sun.
These analyzes could be so detailed
that scientists could see the daily rise and fall of any land surface
The unit rests because the surface expands and contracts with the changes in
Moon's dramatic temperature.
