How NASA, ESA will support ISRO during the Moon landing on August 23
The Hindu ^ | 8/20/2023 | 8.20.2023

Since the launch of the Chandrayaan-3 mission on July 14, the ground stations of the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) have been supporting Indian Space Research Organisation (ISRO) to monitor the spacecraft’s health.

“Since the launch of Chandrayaan-3, ESA has been supporting the mission by utilising two of the ground stations in the ESTRACK network to track the satellite in its orbit, receive telemetry from the spacecraft and forward it to the Mission Operations Centre in Bengaluru, and forward commands sent from Bengaluru to the flying satellite,” Ramesh Chellathurai, ground operations engineer at ESOC Darmstadt, Germany told The Hindu.

The ESA’s 15-metre antenna in Kourou, French Guiana, and the 32-metre antenna belonging to Goonhilly Earth Station, U.K., were selected for the support, based on their technical capabilities as well as their periods of geometric visibility to the satellite.

“These two stations have been communicating with the Chandrayaan-3 mission on a regular basis, providing a complete communication channel between the Mission Operations Team in Bengaluru and the Chandrayaan-3 satellite,” Mr. Chellathurai added.

Now, with the Chandrayaan-3’s Lander making an attempt to touch down on the lunar surface on August 23, the support of the ground stations of these agencies becomes even more crucial.

The ESA’s 35-metre deep space antenna in New Norcia, Australia, a third ground station in the ESTRACK network, has been set-up to track and communicate with the Lander Module during the Lunar Descent phase.

The New Norcia antenna will serve as a back-up for ISRO’s own ground station during the descent. It will receive information about the Lander Module’s health, location and trajectory in parallel with the ISRO station.

“It will be this telemetry that is used to confirm the success of the landing. This type of back-up support is common during the key moments of a space mission, such as a landing. After a successful landing, data collected by the mission’s Rover will be routed via the Lander Module to the ground stations. These valuable scientific data will be received by the antennas in Kourou and Goonhilly and forwarded to the Mission Operations Centre in Bengaluru,” Mr. Chellathurai said.

As far as NASA is concerned, its Deep Space Network is providing telemetry and tracking coverage during the powered descent phase from Deep Space Station (DSS)-36 and DSS-34 at Canberra Deep Space Communications Complex followed by DSS-65 at Madrid Deep Space Communications Complex.

“We receive the telemetry from the spacecraft that has the data on the health and status as well as instrument measurements and pass them on to ISRO in practically real-time. We also monitor the radio signal itself for the Doppler effect, which is the primary tool for navigating the spacecraft. This is the critical information during the landing phase and tells us in real-time how it is doing,” Sami Asmar, Jet Propulsion Laboratory’s Interplanetary Network Directorate Customer Interface Manager, said.

He added that primary support for the mission comes from the DSN complex in California because that is exactly on the other side of the Earth from India and can be in view of the Moon when the station in India cannot see the Moon.

WTF. Why should we help India, using stolen US intellectual property and technology, land on the moon?! Maybe share with them self destruct signal. That should be the limit of the use of US taxpayer resources.

NASA data, largely (not exclusively, but largely) is public domain. Microwave, even the winglets you see on most modern aircraft were researched and designed by NASA; paid by US taxpayers and then given to the world.

That’s entirely different than providing material support, which is what is now occurring and must stop.

I hope they pull off a successful landing and mission. It will be the first time for a lunar landing near the South Pole…. or at least a non crash landing of which there may have been some.

If Chandrayaan-3 comes back, will it be worshipped as a god?

[Why should we help India...]

“...receive telemetry from the spacecraft and forward it...”

Why wouldn’t we? We get free access to the data they collect. Plus they will owe us a favor. Win win.

I do too. I see a vague parallel between the race to reach the earth’s south pole and the moon’s. There were two parties racing each other to reach the earth’s - the English Robert Falcon Scott and the Norwegian Roald Amundsen. Unfortunately Scott perished in the expedition - which is what we learned of the Russian lander today, and Amundsen’s party went ahead to be the first to reach the south pole. Whether the Indians can be the Amundsens of the moon’s southern region, we will see.

It’s a good thing India is not sending a monkey to the moon through the Van Allen Belts. The poor little critter would be fried!

And, since the Indians are the first to send cows into space, NASA was instrumental in devising sensors to monitor methane levels.

“ By the seven arms of Vishnu”

That can’t be. Indian gods always have an even number of arms so they are symmetrical around the body. The number of heads on the other hand (pun not intended ) is always odd to account for the central head that sits on the neck (even + 1)

There is a lot more cooperation. The first presence of water on the moon was detected by a NASA instrument carried aboard Chandrayaan-1 . Even this mission carries a NASA instrument, probably the one which is used to measure the exact distance to the earth.

@Reno You can rant and rave all you want but the Soviets and the French and then the Russians helped the Indian Space programme . Nothing was "stolen", as you put it, from NASA.

Americas biggest contribution to the Indian space programme after 1971 was to force the Russians to stop selling Cryogenic engines to India forcing India to develop them on its own, with "retired" Russian scientists pitching in.
