Happy Rainy Day

It is finally raining several times a day. Sometimes it makes traffic stuck and cause delays.

However the rain is welcome after smeltering heat. Cloudy weather is even more welcome as Sun becomes gruesome after rain and weather becomes souna bath causing profused sweating.

It appears the nature is enjoying too. Check this flower:

Rain may be a spoil sports in clod County but in India it is a poetry, especially this drizzling with occassional pause and small droplets in between.

Chandrayaan 2 launched by India using gravitational pull of Moon.

Who first thought of gravitational pull?

Chandrayan 2 was launched yesterday and it uses the same technology of gravitational pull that was used by Mars mission spcecraft, Mangalyan. The reported mission is stated by ISRO as under:

July 22, 2019 at 14:43 hrs IST from Satish Dhawan Space Center at Sriharikota on-board GSLV Mk-III. It will be injected into an earth parking 170 x 39120 km orbit. A series of maneuvers will be carried out to raise its orbit and put Chandrayaan-2 on Lunar Transfer Trajectory. On entering Moon’s sphere of influence, on-board thrusters will slow down the spacecraft for Lunar Capture. The Orbit of Chandrayaan-2 around the moon will be circularized to 100×100 km orbit through a series of orbital maneuvers. On the day of landing, the lander will separate from the Orbiter and then perform a series of complex maneuvers comprising of rough braking and fine braking. Imaging of the landing site region prior to landing will be done for finding safe and hazard-free zones. The lander-Vikram will finally land near South Pole of the moon on Sep 7, 2019. Subsequently, Rover will roll out and carry out experiments on Lunar surface for a period of 1 Lunar day which is equal to 14 Earth days. Orbiter will continue its mission for a duration of one year.

To understand the technique of using gravitational pull, this picture uploaded by ISRO explains better:

Gurdjieff thought about it much earlier.
