To further strengthen the Indian research community for lunar science studies, Chandrayaan-2 orbiter payloads data are made available to public and scientific proposals are solicited for scientific analysis, it said. Chandrayaan-2 orbiter is cur...

  The Indian Space Research Organisation (ISRO) recently demonstrated free-space quantum communication over a distance of 300 m for the first time. The demonstration included live videoconferencing using quantum-key-encrypted signals. This is a major achievement for unconditionally secured satellite data communication using quantum technologies. Isro said that a number of key technologies were developed indigenously to accomplish this major feat, which included the use of an indigenously developed navigation satellite system, with an operational name of NavIC, a receiver for time synchronisation between the transmitter and receiver modules, and gimbal mechanism systems instead of bulky large-aperture telescopes for optical alignment.

  The Indian space rockets are set to go green as ISRO is working to replace its existing hazardous fuel with non-hazardous and environment- friendly fuels for its rockets and satellites, the ISRO Chairman said. He also said that the Indian Space Research Organisation (ISRO) is looking at green propulsion through hydrogen peroxide in its rocket that would take Indians into the space under its 'Gaganyaan' mission. "Since humans will be inside the rocket, we want only non-hazardous fuel and not the hazardous one to power the human space mission's Gaganyaan rocket ," ISRO chief K Sivan, who is also Secretary in Department of Space, told IANS. According to him, ISRO is also looking at rocket engines powered by hydrogen peroxide as a mono-propellant or as a bi-propellant along with ethanol. ISRO is also developing another green fuel - LOX/Methane- liquid oxygen as oxidiser and methane as fuel. Read More

  After a fast paced race to Mars and plans to return to the moon, there is still something left for science and astronomy enthusiasts in 2020, a rare celestial phenomenon —the Great Conjunction— when Jupiter and Saturn will align to form one of the brightest stars in the night sky on Monday being seperated by just one-tenth of a degree. The planets regularly appear to pass each other in the solar system, with the positions of Jupiter and Saturn being aligned in the sky about once every 20 years. However, this year the conjunction is special as it’s been nearly 400 years since the planets passed this close to each other in the sky, and nearly 800 years since the alignment of Saturn and Jupiter occurred at night. The rare phenomenon can be visible globally including in India between 6:30-7:30 pm. The planets will be easy to see with naked eye by looking toward the southwest just after sunset. Jupiter bigger and closer to Earth will be vastly brighter. Read More  

  The Indian Space Research Organisation (Isro)'s PSLV-C50 lifted off successfully from the Sriharikota spaceport near Chennai. The rocket is carrying orbiting communication satellite CMS-01 (formerly GSAT-12R). The rocket lifted at 3:41 p.m. from the second launch pad at the rocket port in Sriharikota, in Andhra Pradesh. After about 20 minutes into its flight, it will eject CMS-01 into geosynchronous transfer orbit (GTO) and from there, the satellite will be taken up and positioned in the geosynchronous stationary orbit. The 44-metre-high four-staged engine, PSLV-C50, is the 22nd flight of PSLV in 'XL' configuration (with six strap-on motors hugging the first stage). It will be the 52nd mission for India's Polar Satellite Launch Vehicle (PSLV). Read More

The Indian Space Research Organisation has gotten over the setback it suffered on account of the Chandrayaan-2 mission , and has ended the year with six launch vehicle missions and seven satellite missions. The number is lower than that achieved in 2018, when Isro had completed 16 missions and was preparing for some major milestones, including the launch of Chandrayaan-2, preparing for India's first human space programme 'Gaganyaan' and its mission to the Sun: Aditya-1. At the beginning of the year 2019, Isro said it was planning as many as 32 missions, including 14 launch vehicles, 17 satellite and one Technology Demonstration missions. The complex Chandrayaan-2 and the development flights of Small Satellite Launch Vehicle or SSLVs, were an intrinsic part of this plan. SSLVs are the new member in the Launch Vehicle family. After completing 16 missions in 2018, Isro started the year 2019 not with a launch, but with the signing of an MoU with industries to outsourc...

India launched 14 satellites Wednesday morning, boosting the morale of its space agency which lost contact with a spacecraft to trying to land on the moon in September. Polar Satellite Launch Vehicle-C47 (PSLV-C47) placed in orbit India's earth observation satellite Cartosat-3 and 13 nano-satellites for the US when it blasted off from the Indian Space Research Organisation (Isro's) Satish Dhawan Space Centre in Sriharikota at 9:28am. Seventeen minutes after lift-off, Cartosat-3 separated from the launch vehicle and put into orbit. The 13 US satellites will be launched in the next eight minutes, completing the first business order of Isro's newly formed commercial arm NewSpace India Ltd. Cartosat-3, India’s third-generation earth observation satellite, will be used for large-scale urban planning and to monitor coastal land, rural resources and infrastructure development. The satellite, which will last for five years and weighs 1,625kg, can pick a 25-cm object fr...

Indian space agency has released fresh set of pictures of impact craters on moon surface taken by its Chandrayaan-2 Orbiter. The Indian Space Research Organisation (ISRO) on Tuesday releasing a picture on its Twitter handle said the images were taken by the Dual Frequency-Synthetic Aperture Radar (DF-SAR) on its Chandrayaan-2 Orbiter. According to ISRO, the Moon has been continuously bombarded by meteorites, asteroids and comets since its formation. This has resulted in the formation of innumerable impact craters that form the most distinct geographic features on its surface. Impact craters are approximately circular depressions on the surface of the moon, ranging from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins. "In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain," ISRO said.

NASA has found no evidence of Chandrayaan-2's Vikram lander in the images captured during a latest flyby of its Moon orbiter of the lunar region where India's ambitious mission attempted a soft landing, the US space agency said. On September 7, Indian Space Research Organisation (ISRO) attempted a soft landing of Vikram on the uncharted lunar south pole, before losing communication with the lander. "The Lunar Reconnaissance Orbiter imaged the area of the targeted Chandrayaan-2 Vikram landing site on October 14 but did not observe any evidence of the lander," Noah Edward Petro, the Project Scientist for the LRO mission, told PTI in an exclusive email interaction. Petro said that the camera team carefully examined the images and employed the change detection technique -- using a ratio of an image from prior to the landing attempt to the one acquired on October 14. This approach, he said, is used for finding new meteorite impacts on the Moon that also hel...

The Indian Space Research Organisation (Isro) said that it was yet to establish any communication with Chandrayaan-2 's lander, Vikram. On September 7, minutes before landing, Vikram, which was carrying a rover, Pragyan, went out of contact during its final descent, when it was just 2.1 km above the lunar surface. "Vikram Lander has been located by the orbiter of Chandrayaan 2, but no communication with it yet. All possible efforts are being made to establish communication with lander," said Isro. While reports claim that the Vikram lander lies on the lunar surface as a single piece, unbroken, and it is in a tilted position following a hard landing, Isro officials did not confirm, stating that they were trying to establish communication with the lander. Chandrayaan-2 comprises an orbiter, lander (Vikram) and rover (Pragyan). The mission life of the lander and rover is one lunar day, which is equal to 14 Earth days. Isro Chairman K Sivan earlier said that the...
