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

Tata Play starts beaming from its GSAT-24 satellite, to increase capacity

Direct-to-home (DTH) service provider Tata Play on Monday said it has started beaming of television channels from its dedicated GSAT-24 satellite which it has leased from Indian space agency ISRO. GSAT-24 was specifically launched for Tata Play (earlier knows as TataSky) in June last year, which will help increase its carrying capacity to 900 channels and cover the length and breadth of the country including far-flung places like Andaman Nicobar and Lakshsdweep islands. After the launch, ISRO took time to place the satellite in the desired slot of 36,000 kilometre geosynchronous orbit. The satellite was first tested by Indian Space Research Organisation (ISRO) and handed over to Tata Play, which carried out its own tests. Commenting over the development, MD & CEO Harit Nagpal said this will help Tata Play carry 900 channels, including the regional channels and Gyanwani channels, which would be launched by the government. "This will help Tata Play to carry 900 channels from the ...

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

ISRO transfers satellite bus tech to Alpha Design to boost private sector

ISRO on Saturday said it has transferred the IMS-1 Satellite Bus Technology to Alpha Design Technologies Pvt. Ltd in a step towards enhancing private industry participation in the country's space sector. NewSpace India Limited (NSIL), the commercial arm of ISRO, facilitated the technology transfer through an agreement signed during an event held at the NSIL headquarters on August 2, 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. ISRO has been enabling

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

Isro gearing up to launch 'exciting' missions for rest of year: Chairman

ISRO has lined up a series of activities over the next few months as it gears up for "exciting" missions including a GSLV launch this year, Chairman S Somanath said here on Sunday. The space agency, in a precise textbook launch today, successfully placed seven Singaporean satellites into intended orbits on board its trusted workhorse Polar Satellite Launch Vehicle (PSLV). Giving some insights on the future launch campaigns to be taken up by the Bengaluru-headquartered space agency, Somanath said: "We are going to come back with another PSLV mission soon in the month of August or early September." "This year itself, we are going to have exciting missions. The PSLV is going to fly again. We are going to have the Gaganyaan test vehicle which is currently getting integrated," he said while speaking from the Mission Control Centre. According to ISRO, the Gaganyaan project envisages demonstration of human spaceflight capability by launching a crew of three members to an orbit of 400 ...

Isro scientists to perform unique experiment in PSLV-C56 mission launched

Scientists at ISRO, after successfully launching seven Singaporean satellites on Sunday's mission, will attempt a unique experiment using the fourth stage of the PSLV-C56 rocket. While the mission is a follow up to the PSLV-C55 TeLEOS-2 mission launched in April this year, scientists in today's mission will try to place the fourth stage of the PSLV rocket in a lower orbit. According to ISRO, after injecting all the Singapore satellites into the intended orbit at an altitude of about 536 km, the upper stage of the rocket will be placed in lower orbit to ensure its reduced orbital life at an altitude of about 300 km, ISRO said. "PS4 (fourth stage) will be de-orbited to Low Earth circular orbit in a 300x300 km, using left out propellants to reduce orbital life of spent PS4 stage," ISRO said. In April, during the launch of PSLVC55 mission in April, scientists successfully performed another unique experiment where the fourth stage of the PSLV rocket was utilised as an orbital platform t
