Lander Vikram located on Lunar surface: ISRO chief
Bengaluru: The Chandrayaan-2s Vikram module has been located on the Lunar surface and it must have been a hard-landing, ISRO chairman K Sivan said on Sunday, in an admission that the planned soft-landing wasnt successful. Yes, we have located the lander on the Lunar surface. It must have been a hard-landing, Sivan told PTI.
He said the lander rover Pragyan is housed inside it was located by on-board cameras of the Chandrayaan-2 orbiter. Asked if the lander was damaged during the hard-landing, he said: That we do not know.
Sivan said efforts to establish contact with the lander were continuing. India's mission to soft-land on moon suffered a setback during the wee hours on Saturday, with 'Vikram' module losing communication with ground stations, just 2.1 km from the lunar surface during its final descent.
Considered as the most complex" stageof the country's second expedition to the moon, the Lander was on a powered decent for a soft-landing when it lost the communication.
"Vikram Lander descent was as planned and normal performance was observed up to an altitude of 2.1 km. Subsequently, communication from the lander to ground stations was lost," Sivan had said.
"The data is being analysed", he had added at the Mission Operations Complex at ISRO Telemetry, Tracking and Command Network (ISTRAC) here.
The successful landing would have made India the fourth country after erstwhile USSR, the US and China to achieve a soft-landing on the moon, also the first to launch amission to the unexplored south pole of the Moon.
The Chandrayaan-2 orbiter is healthy and safe in the Lunar orbit, an ISRO official said after the lander lost contact with ground stations minutes before the touchdown on Moon's surface.
"The orbiter is healthy, intact, functioning normally and safely in the Lunar orbit," the official told PTI. The mission life of the 2,379-kg orbiter is one year. The orbiter payloads would conduct remote-sensing observations from a 100-km orbit.
Chandrayaan-2, a follow-on mission to the Chandrayaan-1 mission undertaken more than a decade ago, comprises an orbiter, lander (Vikram) and rover (Pragyan).
The orbiter carries eight scientific payloads for mapping the lunar surface and study the exosphere (outer atmosphere) of the Moon.
ISRO on September 2 successfully carried out the separation of lander Vikram (with rover Pragyan housed inside) from the Chandrayaan-2 orbiter.
The Vikram module, which was supposed to carry out various tests on the lunar soil, had completed the rough braking phase as planned and entered the phase of fine braking at an altitude of 2.1 km, when it lost communication.
'Vikram', named after Dr Vikram A Sarabhai, the father of the Indian Space Programme, was designed to execute a soft-landing on the lunar surface, and to function for one lunar day, which is equivalent to about 14 earth days.
The rover was to roll down from the lander explore the surrounding lunar terrain, a few hours after the planned soft-landing. The Chandrayaan-2 is a Rs 978-crore unmanned moon mission (satellite cost Rs 603 crore, GSLV MK III cost Rs 375 crore).
India's Geosynchronous Satellite Launch Vehicle, GSLV MkIII-M1 successfully launched the 3,840-kg Chandrayaan-2 spacecraft into the Earth's orbit on July 22.
The spacecraft began its journey towards the moon leaving the earth's orbit in the dark hours on August 14, after a crucial manoeuver called Trans Lunar Insertion that was carried out by ISRO to place the spacecraft on "Lunar Transfer Trajectory."
The spacecraft successfully entered the lunar orbit on August 20 by performing Lunar Orbit Insertion (LOI) manoeuver.
On September 2, 'Vikram' successfully separated from the orbiter, following which two de-orbiting manoeuvres were performed to bring the lander closer to the Moon

ISRO successfully conducts second integrated air drop test for Gaganyaan mission
New Delhi (PTI): Space agency ISRO has successfully conducted the second integrated air drop test (IADT-02) for the upcoming Gaganyaan mission at the space station in Andhra Pradesh's Sriharikota.
The system is essential to ensure a safe recovery of the crew module -- the capsule in which astronauts sit during a human flight -- during re-entry and landing.
Union minister Jitendra Singh congratulated the Indian Space Research Organisation (ISRO) for successfully conducting the test.
"Congratulations #ISRO for the successful accomplishment of Second Integrated Air Drop Test (IADT-02) for #Gaganyaan, India's first Human Space flight scheduled next year. The second Integrated Air Drop Test (IADT-02) was successfully conducted at Satish Dhawan Space Station Sriharikota," Singh said in a post on X.
The IADT-02 follows the successful completion of the first IADT, which took place on August 24, 2025, at the Satish Dhawan Space Centre in Sriharikota.
Air drop tests recreate the last leg of a spacecraft's return to Earth. An aircraft or helicopter drops the spacecraft from a height to test various systems under different scenarios.
These are the deployment of the parachute system in case the mission is aborted mid-flight, system performance when one parachute fails to open and the spacecraft's orientation and safety during splashdown etc.
In the IADT-02 test, a simulated crew module, weighing about 5.7 tonnes, was lifted by an Indian Air Force Chinook helicopter to an altitude of about three kilometres and released over a designated drop zone in the sea, near the Sriharikota coast.
In a statement, the ISRO said, "Ten parachutes of four types were deployed in a precise sequence during the descent of the crew module, gradually reducing the velocity for safe touchdown. Subsequently, the simulated crew module was successfully recovered in coordination with the Indian Navy."
