The Chandrayaan-3 spacecraft on Sunday successfully entered the lunar orbit.  If the rest of the current mission goes to plan, the mission will safely touch down near the Moon's little-explored south pole between August 23 and 24. Since its launch on July 14, ISRO has been lifting the Chandrayaan-3 spacecraft into orbits farther and farther away from Earth.

Significance of Chandrayaan 3 for India

If the robotic lunar rover of Chandrayaan-3 successfully lands on the moon, India will achieve the distinction of being the fourth country to have mastered the technology of soft-landing on the lunar surface, following the United States, China, and the former Soviet Union. Chandrayaan-3 marks the Indian Space Research Organisation's (ISRO) second attempt in the span of four years, with its initial lunar mission, Chandrayaan-1, taking place in 2008. Unfortunately, the subsequent mooncraft mission, Chandrayaan-2, encountered failure during its lunar phase when its lander named 'Vikram' crash-landed due to anomalies in the braking system while attempting a soft landing on September 7, 2019.

Sling-shot mechanism used for launch as our rockets not powerful: ISRO

"Our rockets (launch vehicles) are not very powerful. Once the rockets escape the earth, they need a velocity of 11.2 km/s to make further progress. Since our launch vehicles don't operate at such velocity, we resorted to the sling-slot mechanism," ISRO scientist Tapan Mishra told ANI.

How Chandrayaan-3 Mission is different form its predecessor

The significance about Chandrayaan-3 mission, unlike its unsuccessful predecessor, is that the Propulsion Module has a payload -- SHAPE -- Spectro- polarimetry of HAbitable Planet Earth which is to study earth from lunar orbit.

The ISRO said the SHAPE is an experimental payload to study the spectro-polarimetric signatures of the Earth in the near-infrared wavelength range.

Apart from the SHAPE payload, the Propulsion Module's main function is to carry the Lander Module from launch vehicle injection orbit till lander separation.

The Lander Module after landing on the surface of the moon has payloads including RAMBHA-LP which is to measure the near surface plasma ions and electrons density and its changes, ChaSTE Chandra's Surface Thermo Physical Experiment -- to carry out the measurements of thermal properties of lunar surface near polar region-- and ILSA (Instrument for Lunar Seismic Activity) to measure seismicity around the landing site and delineating the structure of the lunar crust and mantle.

The rover, after the soft-landing, would come out of the Lander Module and study the surface of the moon through its payloads APXS - Alpha Particle X-Ray Spectrometer

Chandrayaan-3 Mission: 'A moment of glory' for India

The Chandrayaan-3 spacecraft has taken much longer to reach the Moon than the manned Apollo missions of the 1960s and 1970s, which arrived in a matter of days.

The Indian rocket used is much less powerful than the United States' Saturn V and instead the probe orbited the earth five or six times elliptically to gain speed, before being sent on a month-long lunar trajectory.

If the landing is successful the rover will roll off Vikram and explore the nearby lunar area, gathering images to be sent back to Earth for analysis.

The rover has a mission life of one lunar day or 14 Earth days.

ISRO chief S. Somanath has said his engineers carefully studied data from the last failed mission and tried their best to fix the glitches.

Chandrayaan enters lunar orbit: What next?

Chandrayaan-3, which means "Mooncraft" in Sanskrit, had been "successfully inserted into the lunar orbit" on Saturday (5 August), more than three weeks after its launch.

Tonight, the Indian spacecraft will maneuver further at 11 PM, and there will be three more operations till August 17 following which the Landing Module Vikram carrying the rover Pragyan inside will break away from the Propulsion Module. After this, de-orbiting maneuvers will be carried on the lander before the final powered descent on the moon expected on 23 or 24 August.

Chandrayaan-3's message to ISRO: 'I am feeling...'

Chandrayaan-3, India's third unmanned Moon mission yesterday entered the lunar orbit, 22 days after it was launched for a far more complicated 41-day voyage to reach the lunar south pole where no other nation has gone before.

After reaching the lunar's orbit, Chandrayaan messaged ISRO saying, "I am feeling lunar gravity".

The ISRO shared a message from the satellite to its centres, which read," MOX, ISTRAC, this is Chandrayaan-3. I am feeling lunar gravity".

Chandrayaan-3 news: What next in the ISRO's Moon mission?

The next Lunar bound orbit manoeuvre is scheduled tomorrow, around 23:00 hrs IST. Throughout the first weeks of August, the craft is set to complete 5-6 orbits around the moon, gradually transitioning to a circular 100-kilometre orbit. Over the following ten days, a precise landing site within the moon's south pole area will be determined. Subsequently, the lander will deorbit and initiate a soft landing attempt on August 23 at 5:47pm.

ISRO remains attentive to the lunar landing schedule, considering factors such as the moon's sunrise. If required, the landing may be rescheduled for September. With each accomplished milestone, India's Chandrayaan-3 mission continues its journey towards an unprecedented lunar landing achievement. (HT)

ISRO transfers satellite bus technology to private firm

In a step towards enhancing private industry participation in the country's space sector, the Indian Space agency, ISRO, on 5 August said it has transferred the IMS-1 Satellite Bus Technology to Alpha Design Technologies Pvt. Ltd, reported Hindustan Times. 

On August 2, the commercial arm of ISRO, NewSpace India Limited (NSIL), facilitated the technology transfer through an agreement signed during an event held at the NSIL headquarters, the space agency said on its website.

The technology transfer documents were formally handed over by D Radhakrishnan, Chairman and Managing Director of NSIL to Col. H S Shankar (Retd.), Chairman and Managing Director of ADTL.

ADTL is one of the two private players identified to receive the transfer of this technology through Interest Exploratory Note (IEN) published by NSIL, it said.

This transfer marks the beginning of satellite bus technologies developed by ISRO being transferred to private industries. Further, the PSLV is under productionisation by a consortium of industries.

Chandrayaan-3 Mission launch: A flashback

Chandrayaan-3 is India’s third lunar exploration mission. It was launched on GSLV Mark 3 (LVM 3) heavy-lift launch vehicle successfully from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota on 14 July.

Chandrayaan-3 is the ISRO's follow-up attempt after the Chandrayaan-2 mission faced challenges during its soft landing on the lunar surface in 2019. Chandrayaan-2 was eventually deemed to have failed its core mission objectives.

With Chandrayaan-3, India can become the fourth country after US, China, and Russia, to land its spacecraft on the surface of the moon and demonstrate the country’s ability for safe and soft landing on the lunar surface.
