Before the launch of Chandrayaan 2, ISRO tweets 4 theories behind the origin of Moon

The Indian Space Research Organization (ISRO) has planned four interesting theories just before its long-awaited launch of Chandrayaan 2 on July 15th. In a tweet, the Indian space agency published a photo and presented four theories about the origin of the moon.

ISRO tweeted: "Which of these theories is correct, is there a fifth alternative that no one else has considered?" We are looking for an answer to these questions and more through Chandrayaan 2 – the first mission in the southern polar region of the Moon! "

Theory of fission

The speed of rotation of the Earth caused the planet's moon to split, while its gravitational pull anchored this fragment to become our natural satellite.

Hypothesis of the giant impact

A collision between the Earth and another celestial body caused the rupture of a segment of the planet and the transformation of the Moon.

Theory of co-accretion

A single cloud of gas created the Moon and Earth as it gravitated around a black hole.

Capture Theory

The Moon was an unattached object before being captured by the gravitational field of the Earth during a passage.

The Chandrayaan-2 mission includes Orbiter, Lander and Rover. He will be in space for 59 days before landing in September. The radar will move and the mobile will transport the samples.

The mission will have 14 scientific instruments (payloads), of which 8 in the orbiter, 4 in lander and 2 in rover. One of the instruments of the rover is a passive instrument of the US space agency, NASA.

ISRO baptized the lander "Vikram" after the pioneer of the Indian space industry Vikram Sarabhai (1919-1971) and the device "Pragyan", which in Sanskrit means "wisdom".

"The rocket will place the orbiter on the geo-transfer orbit for its lunar orbit, covering 385,000 km of Earth to Moon in 50 days for the landing gear to have a soft landing near from its south pole on September 6th, "says Sivan.

The rocket will separate the orbit a few minutes after launch, 170 km from the perigee (closer to the Earth) and 38,000 km from the apogee (away from the Earth). September 6 at 100 km from the lunar surface.
