"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.

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.

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.

Even as air pollution remains mostly urban centric, studies have well established the regional scale pollution is more concentrated in the Indo-Gangetic plains because of the peculiar meteorology and also in more industrialised states. Apart from Delhi-NCR, there are scores of other polluted cities across India that too need attention and the NCAP by the Ministry of Environment, Forests and Climate Change (MoEF&CC) does that.

The rare occurrence in the nearby universe indicates that small merging groups are ideal laboratories to detect multiple accreting supermassive black holes and increases the possibility of detecting such occurrences. Supermassive black holes are difficult to detect because they do not emit any light, but can reveal their presence by interacting with their surroundings.

Dubbed as 'Hycean' -- hot, ocean-covered planets with hydrogen-rich atmospheres, the new class of exoplanets are more numerous and observable than Earth-like planets, and can support life, said astronomers from the University of Cambridge in the UK. The results, reported in The Astrophysical Journal, could mean that finding biosignatures of life outside our Solar System .

As of August 15, Zhurong had worked on the surface of Mars for 90 Martian days, or about 92 days on Earth, with all scientific payloads having started to work on detection tasks, the Xinhua news agency quoted the China National Space Administration (CNSA) as saying. The CNSA added that the rover will continue to move to the boundary zone between the ancient sea and the ancient land in the southern part of Utopia Planitia, and will carry out additional tasks.

Asteroid impacts and solar radiation affect the moon in unique ways because it lacks the protective magnetic field and atmosphere that protect us here on Earth. Both asteroids and solar radiation break down lunar rocks and soil, forming iron nanoparticles (some smaller, some larger) that are detectable from instruments on satellites orbiting the moon.

The rover will drive to a new location called Citadelle for a second shot at picking up its first rock sample. "This time, to make sure a sample is actually collected, engineers will wait for images of the sample tube to come back before it gets processed and stowed inside the rover's belly," reports The Verge. "The rock simply wasn't our kind of rock,".

Space radiation originates from three primary sources: particles trapped in the Earth's magnetic field, particles shot into space during solar flares, and galactic cosmic rays, which originate outside our solar system. Published in the journal Nature-Scientific Reports, results from an ISS Medical Monitoring study of International Space Station astronauts demonstrate how the sensitivity of an individual astronaut's DNA to radiation exposure on Earth can predict their DNA's response during spaceflight as measured by changes to their chromosomes.
