Chandrayaan-3 completes last Moon-bound manoeuvre, gears up for propulsion

India's ambitious Chandrayaan-3 mission hit another mark on Wednesday when its spacecraft successfully underwent a fifth and final lunar-bound orbit manoeuvre, which brings it even closer to the surface of the Moon. With this, the spacecraft has completed all of its Moon-bound manoeuvres, and it will now prepare for separation of the lander module -- comprising the lander and rover -- from the propulsion module. "Today's successful firing, needed for a short duration, has put Chandrayaan-3 into an orbit of 153 km x 163 km, as intended. With this, the lunar bound manoeuvres are completed. It's time for preparations as the Propulsion Module and the Lander Module gear up for their separate journeys," ISRO said in a post on X (formerly Twitter). Separation of the lander module from the propulsion module is planned for August 17, it said. Following its launch on July 14, the Chandrayaan-3 spacecraft entered into lunar orbit on August 5, following which orbit reduction manoeuvres were ..

Chandrayaan-3 undergoes orbit reduction manoeuvre, closer to Moon's surface

Chandrayaan-3 ventured closer to the lunar surface on Monday with another successful maneuver of the spacecraft by ISRO, the national space agency said. The Bengaluru-headquartered space agency said the spacecraft has now achieved a "near-circular orbit" around the Moon. Post its launch on July 14, Chandrayaan-3, the country's ambitious third Moon mission, had entered into lunar orbit on August 5, following which two orbit reduction maneuvers were carried out on the spacecraft on August 6 and 9. "Orbit circularisation phase commences. Precise maneuver performed today has achieved a near-circular orbit of 150 km x 177 km," ISRO said in a tweet. The next operation is planned for August 16, around 08.30 am, it said. As the mission progresses, a series of maneuvers is being conducted by ISRO to gradually reduce Chandrayaan-3's orbit and position it over the lunar poles. According to ISRO sources, one more maneuver will be performed on the spacecraft on August 16 to reach 100 km orbit

Isro congratulates Russia on the launch of Luna-25 mission to Moon

The Indian Space Research Organisation (ISRO) on Friday congratulated the Russian State Space Corporation, Roscosmos, for the successful launch of Luna-25, Russia's moon mission. "Congratulations, Roscosmos on the successful launch of Luna-25 Wonderful to have another meeting point in our space journies Wishes for Chandrayaan-3 & Luna-25 missions to achieve their goals," ISRO tweeted on Friday. Russia on Friday launched Luna 25, the country's first lunar mission in 47 years. Luna-25 took off from the Vostochny launch facility in Russia's Far East, the Russia-based TASS news agency reported. Launched aboard a Soyuz-2 Fregat rocket, Luna 25 took flight at 8:10 am (local time) on Friday, CNN reported. The Fregat booster separated from the rocket's third stage approximately 564 seconds after the launch, according to TASS reported. The Luna-25 spacecraft will separate from the booster about an hour after the launch. The flight to the moon will take up to 5.5 days. The spacecraft will

Isro plans proper touchdown of Vikram lander even if sensors, engines fail

Vikram, the lander of India's third lunar mission Chandrayaan-3, will be able to make a soft-landing on the Moon's surface on August 23 even if all the sensors and two of its engines do not work, ISRO chairman S Somanath said on Tuesday. The entire design of the lander Vikram' has been made in a manner that makes sure that it would be able to handle failures, Somanath said during a talk on Chandrayaan-3: Bharat's Pride Space Mission', hosted by the non-profit organisation Disha Bharat. If everything fails, if all the sensors fail, nothing works, still it (Vikram) will make a landing. That's how it has been designed -- provided that the propulsion system works well, Somanath said. Chandrayaan-3 blasted into Space on July 14 and it entered into lunar orbit on August 5. There will be three more de-orbiting manoeuvres -- exercises to bring it closer to the Moon so that Vikram lands on the Moon's surface on August 23. These de-orbiting manoeuvres will be performed on August 9, August 14

Lowering Chandrayaan-3 from 100 km orbit very critical phase: Isro chief

India's third lunar mission Chandrayaan-3 is in good health and its most critical phase will be the orbit determination process when the spacecraft starts moving closer to the moon from the 100 km circular orbit, Indian Space Research Organisation Chairman S Somanath said on Monday. Launched on July 14 by the Launch Vehicle Mark-3 rocket, Chandrayaan-3 spacecraft is now placed in a 170 km by 4,313 km elliptical orbit around the moon and a series of manoeuvres are planned for August 9 and 17 to place it in a 100 km circular orbit. The Vikram lander is expected to descend on the moon on August 23. "Up to 100 km we do not see any difficulty. The issues are only in estimation of the position of the lander accurately from earth. This measurement is a very critical measurement, we call it the orbit determination process. If it is correct, the rest of the process can be done," Somanath told PTI here. "We are able to bring it down very correctly this time. The orbit changes are happening

Chandrayaan-3 successfully inserted into the lunar orbit, says Isro

India's ambitious third moon mission, Chandrayaan-3 was successfully inserted into the lunar orbit on Saturday, the ISRO said. The required maneuver was done from an ISRO facility here, the city-headquartered space agency said in a tweet. "Chandrayaan-3 has been successfully inserted into the lunar orbit. A retro-burning at the Perilune was commanded from the Mission Operations Complex (MOX), ISTRAC ( ISRO Telemetry, Tracking and Command Network ) , Bengaluru," the agency said in a tweet. Perilune is the spacecraft's closest point to the moon. The next operation - reduction of orbit will be done at 11 PM on Sunday, ISRO added. ISRO also shared a message from the satellite to its centres, which read,"MOX, ISTRAC, this is Chandrayaan-3. I am feeling lunar gravity." Over five moves in the three weeks since the launch on July 14, ISRO has been lifting the Chandrayaan-3 spacecraft into orbits farther and farther away from the Earth. Then, on August 1 in a key maneuver -- a slingshot

Chandrayaan covers 2/3rd of distance to Moon, Lunar Orbit Injection on Sat

The Chandrayaan-3 spacecraft has covered about two-thirds of the distance to the Moon since its launch on July 14, ISRO said on Friday. Over five moves in the three weeks since, ISRO has been lifting the Chandrayaan-3 spacecraft into orbits farther and farther away from Earth, and on August 1 in a key manoeuvre -- a slingshot move -- the craft was sent successfully towards the Moon from Earth's orbit. Following the trans-lunar injection, the Chandrayaan-3 spacecraft escaped from orbiting the Earth and began following a path that would take it to the vicinity of the moon. Tomorrow, in another crucial manoeuvre the spacecraft will be injected into Moon's orbit. The Lunar Orbit Injection (LOI) is set for around 7 pm on August 5, the Bengaluru-headquartered national space agency said on Friday. The manoeuvre will be performed when Chandrayaan-3 is at the closest point to the Moon (perilune), ISRO said. The space agency said that the health of India's third lunar mission is normal and
