Perseverance's rock sample to give insight into Mars' history
Analysis of the rocks from which the Montdenier and Montagnac samples were taken show signs that they were in contact with water for a long period of time, boosting the case for ancient life on the Red Planet. aceIt looks like our first rocks reveal a potentially habitable sustained environment. It's a big deal that the water was there for a long time," said Ken Farley of Caltech.
'Will we see humans as machines?'
Welga Ramirez, executive bodyguard and ex-Special Forces, is about to retire early when her client is killed in front of her. It's 2095 and people don't usually die from violence. Humanity is entirely dependent on pills that not only help them stay alive but also allow them to compete with artificial intelligence in an increasingly competitive gig economy.
NASA confirms James Webb telescope launch in December
The agency set the new target launch date in coordination with Arianespace after Webb recently and successfully completed its rigorous testing regimen -- a major turning point for the mission, NASA said in a statement on Wednesday. The new date also follows French company Arianespace successfully launching an Ariane 5 rocket in late July and scheduling a launch that will precede Webb.
Milky Way galaxy is not homogeneous as previously thought
Until now, theoretical models considered that these three elements were homogeneously mixed and reached the Solar composition everywhere in our galaxy, with a slight increase in metallicity in the centre, where the stars are more numerous. For 25 hours, a team of scientists observed the atmosphere of 25 stars using Hubble and the Very Large Telescope (VLT) in Chile.
ISRO commemorates two years of Chandrayaan-2 Orbiter
Chairman and Secretary, Department of Space K. Sivan inaugurated two day Lunar Science Workshop 2021 on Monday. He also released Chandrayaan-2 data product and science documents, along with data from Chandrayaan-2 orbiter payloads. The eight payloads onboard Chandrayaan-2 are conducting scientific observations of the Moon by remote sensing and in-situ techniques.
Coronavirus epidemics 1st hit over 21,000 years ago: Study
The study, published in the journal Current Biology, showed that humanity may have been exposed to sarbecoviruses -- which has the potential to jump from animals to humans -- since the Paleolithic period -- roughly 2.5 million years ago to 10,000 BC. Despite having a very rapid rate of evolution over short timescales, to survive, viruses must remain highly adapted to their hosts -- this imposes severe restrictions on their freedom to accumulate mutations without reducing their fitness.
NASA's Mars rover makes 2nd attempt to pick up rock sample
"The data received on September 1, from NASA's Perseverance rover, indicates that the team has achieved its goal of successfully coring a Mars rock. The initial images downlinked after the historic event show an intact sample present in the tube after coring," the US space agency said in a statement.
Four Indian astronauts to return to Moscow to try out spacesuits
"We are working out their travel schedule. They may be there for two weeks," the Indian Space Research Organisation (ISRO) official, who did not want to be identified, told IANS. Three of the four Indian astronauts will be part of India's Rs 10,000 crore human space mission 'Gaganyaan'. According to the official, the four astronauts will try out their spacesuits designed and made by a company called Zvezda located near Moscow.
S Korea's lunar orbiter on track for launch next year
South Korea aims to conduct a yearlong mission to observe the moon through an orbiting spacecraft, with hopes of securing technologies for future space exploration missions. The Ministry of Science and ICT said it has completed rigging a high-precision camera, developed by the U.S. National Aeronautics and Space Administration (NASA), on the orbiter, which will gather data of the moon's surface to support the US-led Artemis programme.
Scientists decode mystery of brown dwarfs
Brown dwarfs are astronomical objects with masses between those of planets and stars. The question of where exactly the limits of their mass lie remains a matter of debate, especially since their constitution is very similar to that of low-mass stars. One of the clues the scientists found to show these objects are brown dwarfs is the relationship between their size and age.
