Why no one talking about Chandrayaan 2?

India has successfully launched a mission to soft land a rover on the moon, in a landmark moment for a nation trying to become a space superpower.
The country's latest lunar mission, Chandrayaan-2, which means "moon vehicle" in Sanskrit, took off from the Satish Dhawan Space Center at Sriharikota in Andhra Pradesh state at 2:43 p.m., Monday local time (5:13 am ET).

Description

Chandrayaan 2 is an Indian Space Research Organization (ISRO) mission comprising an orbiter and a soft lander carrying a rover, scheduled to launch to the Moon in July 2019. The primary objective of Chandrayaan-2 is to demonstrate the ability to soft-land on the lunar surface and operate a robotic rover on the surface. Scientific goals include studies of lunar topography, mineralogy, elemental abundance, the lunar exosphere, and signatures of hydroxyl and water ice.
Spacecraft and Subsystems
The Chandrayaan 2 orbiter is a box-shaped craft with an orbital mass of 2379 kg and solar arrays capable of generating 1000 W power. The orbiter communicates with the Indian Deep Space Network and the lander. The orbiter will have a scientific payload comprising a visible terrain mapping camera, a neutral mass spectrometer, a synthetic aperture radar, a near infrared spectrometer, a radio occultation experiment, a soft X-ray spectrometer and solar X-ray monitor.
The lander, named Vikram, has a mass of 1471 kg (including the rover), and can generate 650 W of solar power. The lander can communicate directly to the Indian Deep Space Network, the orbiter, and the rover. The lander will carry a camera, seismometer, thermal profiler, Langmuir probe, and a NASA-supplied laser retroreflector.
The rover, Pragyan (also Pragyaan), is a 6-wheeled vehicle with a mass of 27 kg that runs on 50 W of solar power and can travel up to 500 m at a speed of 1 cm per second. The rover communicates directly with the lander. the rover will hold cameras, alpha-proton X-ray spectrometer, and a laser-induced ablation spectroscopy experiment.
Mission Profile
Chandrayaan 2 is launched on 22 July 2019 at 9:13 UT (2:43 p.m. Indian Standard Time) from Satish Dhawan Space Center on Sriharikota Island on an ISRO Geosynchronous Satellite Launch Vehicle (GSLV) Mark III. The lander-orbiter pair will go into an initial elliptical (170 x 40400 km altitude) Earth parking orbit, followed by a trans-lunar injection. The pair go into an initial elliptical lunar orbit on 5 or 6 August. After orbit insertion, the lander and orbiter separate. The orbiter evolves into a 100 km altitude circular polar orbit and the lander brakes from orbit and lands on the surface in the high latitude areas near the south pole, planned for 6 or 7 September. The orbiter portion of the mission is planned to last 1 year. The rover will be deployed using a ramp shortly after landing. The lander and rover portions of the mission are planned for 14-15 days, one period of lunar daylight.

Yes Doctor,
This thought passed on in my mind too.
I saw the whole event in TV. It was a scientific marvel executed by our Scientists under the leadership of Dr.K.Sivan, who is born in a Village near Nagarkoil, Tamil Nadu.
Dr. K.Sivan is the son of a farmer. who studied in a local Government School, in Tamil Medium. He is self made, studious, hard working student, never had tution or gone to coaching classes.

All credit should go to Dr.Sivan and his dedicated team, who have achieved this meritorious success of "Chandrayaan 2, Mission".
Congratulations,

Brahmanyan,

The more one ponders on this extraordinary achievement, and the consistent and continued success over 50 yrs, maybe we should get Mr. Sivan and team to lead the country for the next 25 yrs, so they can take india to a fully developed country in all aspects !

Seeing how the right is running helter skelter when anyone asks for results, it is abundantly clear, that it is beyond the govt capability to transform this country.

The only way we stand to have any chance of success is to get the best of the best to run the country !

Now, spare the sermons on how space scientists cannot run the country, and they don't understand the people's problems of food, water shelter, and only uneducsted, criminals, and thugs understand, etc...LOL
