Astronauts prep ISS for new solar panels

-

 Spacewalking astronauts ventured out on Sunday to install support frames for new, high-efficiency solar panels arriving at the International Space Station later this year. Nasa’s Kate Rubins and Victor Glover put the mounting brackets and struts together, then bolted them into place next to the station’s oldest and most degraded solar wings. They had to lug out the hundreds of pounds of mounting brackets and struts in 2.5 metre duffle-style bags. The equipment was so big and awkward that it had to be taken apart like furniture, just to get through the hatch. With more people and experiments flying on the space station, more power will be needed to keep everything running, according to US space agency Nasa. The six new solar panels — to be delivered in pairs by SpaceX over the coming year or so — should boost the station’s electrical capability by as much as 30%.

Golden Globes to launch a pandemic-era Hollywood awards season

  Los Angeles : Hollywood’s award season kicks off on Sunday at a very different Golden Globes, with a mainly virtual ceremony set to boost or dash the Oscars hopes of early frontrunners like   Nomadland   and   The Trial of the Chicago 7 . Usually a star-packed, laid-back party that draws Tinseltown’s biggest names to a Beverly Hills hotel ballroom, this pandemic edition will be broadcast from two scaled-down venues, with essential workers among the few in attendance. Deprived of its usual glamour, the Globes remain a coveted prize, and a high-profile source of momentum in the run-up to the season-crowning Oscars, which were pushed back this year to April. Nomadland , Chloe Zhao’s paean to a marginalised, older generation of Americans roaming the West in rundown vans, has long been viewed as a frontrunner for the Globes’s top prize. But it will face stiff competition from Aaron Sorkin’s  Chicago 7 , a courtroom drama about the city’s anti-war riots in 1968 with...

  NEW DELHI : Invoking his government’s Atmanirbhar Bharat initiative, Prime Minister Narendra Modi on Sunday said self-reliance is not just a government policy but a national spirit. “When every countryman takes pride, every countryman connects; self-reliant India doesn’t remain just an economic campaign but becomes a national spirit,” said Modi as he mentioned a series of Made in India achievements — from fighter plane Tejas to vaccines — in his monthly radio address Mann ki Baat. Making a pitch for rainwater harvesting, Modi announced the “Catch The Rain” campaign as part of which he urged the citizens to conserve rainwater for 100 days during monsoons. With most areas of the country expected to start receiving rain in May-June, the PM asked the people to start preparations for rainwater harvesting. “We shall have to understand our collective responsibilities with regard to water. Can we right away start a 100-day campaign for the sake of cleaning up water sources around us and ...

  Ahmedabad : India will be without pace spearhead Jasprit Bumrah in the final Test against England after the 27-year-old was released from the squad for personal reasons, the BCCI said on Saturday. The right-arm seamer took four wickets in the opening Test in Chennai but was rested for the second match, which India won to level the series. Bumrah returned to play his first test at his home ground in Ahmedabad, where India triumphed inside two days to go 2-1 up in the four-match series. “Jasprit Bumrah made a request to BCCI to be released from India’s squad ahead of the fourth Test owing to personal reasons,” the board said. “Accordingly, the fast bowler has been released and he will not be available for selection for the fourth test,” it added. India have decided not to add any player to cover for his absence for the final Test, also in Ahmedabad from Thursday. Bumrah had a limited role in the third Test, where spinners Axar Patel and Ravichandran Ashwin wreaked havoc. The bowle...
