Rosetta's Philea space probe recently re-established radio contact with Earth from its distant comet 67P and sent a stream of science data just before low battery power dropped it into standby mode.
On Monday, ISRO scientists will run a test of the Mars orbiter satellite's main engine and make a small course correction. This is crucial because the engine has been idle for nearly 10 months. T E Narasimhan reports
The Chinese Mars probe named Tianwen 1, or Quest for Heavenly Truth 1, will fulfil three scientific objectives: orbiting the red planet for comprehensive observation, landing on Martian soil and sending a rover to roam the landing site.
India's observatory will be the fourth in space, after the Hubble, Russia's Spektr R and Suzaku of Japan.
The threat of landslides and mudslides remains high in the earthquake-hit Nepal in the coming weeks, and the risk is likely to increase when the monsoon rains arrive this summer, scientists have warned.
The unmanned space telescope, which launched in 2009, leaves a legacy of more than 2,600 planet discoveries from outside our solar system
If successful, this would increase capacity to hurl small satellites into space, meeting both local demand and serving global customers.
The warmest six years have all been since 2015, with 2016, 2019 and 2020 being the top three. The differences in average global temperatures among the three warmest years are indistinguishably small. The average global temperature in 2020 was about 14.9C, 1.2 ( 0.1) C above the pre-industrial (1850-1900) level.
Asked if the lander was 'damaged' during the 'hard landing", Sivan said: "That we do not know".
The report claims that the military experts who have analysed the evidence collected by its Investigative Unit say an airstrip under construction in Agalega will almost certainly be used for maritime patrol missions by the Indian Navy.
The Mars mission is overwhelmingly irrelevant to space science and won't advance the frontiers of knowledge. It will divert attention from the real technological challenges facing the Indian space programme, and will further distort our science and technology priorities, says Praful Bidwai.
The ISRO is aiming for a soft landing of the lander in the South Pole region of the moon where no country has gone so far.
The central government's Air Quality Early Warning System for Delhi said a significant increase in the number of "fire points" was observed over Punjab (around 3,000), Haryana and Uttar Pradesh on Wednesday, which is likely to impact the air quality of Delhi-NCR and other parts of northwest India.
The launch of a Geosynchronous Satellite Launch Vehicle was called off by the Indian Space Reasearch Organisation at the eleventh hour on Monday due to a fuel leak in its second stage -- in a setback to the mission to test its homegrown cryogenic engine -- after its failure three years ago.
Signs of alien life will be detected by 2025, while "definitive evidence" of extra-terrestrial beings may be found within the next 20 to 30 years, top NASA scientists say.
'All enemy positions lay exposed, providing immense information to the Indian Army and IAF to conduct successful flushing out operations.'
Mars has belts of glaciers consisting of frozen water equivalent to over 150 billion cubic metres -- enough to cover the entire surface of the red planet with more than one metre of ice, scientists say.
Indian Space Research Organisation's plan to soft land Chandrayaan-2's Vikram module on the Lunar surface did not go as per script in the early hours of Saturday, with the lander losing communication with ground stations during its final descent.
It has already tasted success with the moon mission and Mangalyaan. Is man in space the next frontier for ISRO?
"I am extremely happy to announce that GSLV Mark III successfully injected Chandrayaan 2 in the defined orbit, infact the orbit is 6,000 km more than what was intended," Sivan said.
'If a small object of less than 100 gm can make a deep crater and also release this kind of energy, it could only be a meteorite.'
The mission's findings will help researchers improve their forecasts of space weather events, which have the potential to damage satellites and harm astronauts on orbit, disrupt radio communications and, at their most severe, overwhelm power grids, NASA said.
'Wherever in the world there is political instability, those countries are beset with severe crises today. But India is in a much better position than the rest of the world due to the decisions taken by my government in the national interest,' President Droupadi Murmu said in her address to both Houses of Parliament.
It has also advanced into most parts of Tamil Nadu, some parts of south interior Karnataka and remaining parts of south Bay of Bengal, according to IMD.
It is believed that the crop residue burning in the nearby states of Punjab and Haryana are contributing to polluting the air.
If you want a reminder of just how gorgeous our universe is, then take some time to browse the winners of the 2020 Insight Investment Astronomy Photographer of the Year competition. French photographer Nicolas Lefaudeux took the top prize with a tilt-shift perspective on the Andromeda Galaxy. The winning images are part of an exhibition opening on October 23 at the National Maritime Museum in London and have been collected into a book. Cue some truly innovative an unexpected captures of galaxies, nebulae, planets, the Moon and even SpaceX satellites.
Using data collected by India's Chandrayan mission, NASA has detected magmatic water locked under the surface of the Moon.
Nail-biting moments gave way to celebratory mood at the command centre of Indian Space Research Organisation in Bangalore on Wednesday, as its Mars Orbiter Mission or Mangalyaan entered the red planet's orbit.
The world endured bushfires, drought, tsunamis and earthquakes in 2018.
'Nehru is often portrayed as a visionary with his head in the clouds. But he had his feet firmly planted on the ground when it came to building and nurturing institutions and setting them on the right path with the right traditions,' says B S Raghavan.
