In an unexpected turn of events, NASA has joined environmentalists, tribal leaders, and concerned citizens in growing opposition against lithium mining in Nevada. The unusual alliance stems from the concern that mining activities may interfere with satellite calibration. The arid expanses of Nevada, once home to ancient lake beds, are abundant in lithium. This mineral […]
NASA has discovered that perovskite solar cells might be more effective in the vacuum of space than on Earth, showing a slower rate of degradation. The administration has been actively assessing how perovskite solar cells fare in outer space, specifically concerning their performance and durability. Their research, spanning 10 months, monitored the functioning of these […]
Due to Earth’s continuous warming trend, global temperatures in 2022 were 1.6 degrees Fahrenheit above the average for NASA’s baseline period, which is from 1951-1980. Earth’s average surface temperature in 2022 tied with 2015 was the fifth warmest on record, according to a report by NASA. Due to Earth’s continuous warming trend, global temperatures in […]
A fortnight after NASA went to town with its success in changing the orbit of a flyby asteroid, Mayor, 80, professor emeritus at department of astronomy, University of Geneva, says he is a “little sceptical”. “Don’t worry about asteroids, focus on climate change, it is more immediate and catastrophic.” Sir Michel Mayor, the 2019 Nobel […]
Washington: Raising an alarm over human-caused climate change, NASA-led research has revealed that the amount of heat trapped by Earth’s land, ocean and atmosphere has doubled over the course of only 14 years. Scientists at NASA and the National Oceanic and Atmospheric Administration (NOAA) in the US found that Earth’s energy imbalance approximately doubled during […]
Science-fiction writer Isaac Asimov is credited with bringing the idea of space-based solar power projects to prominence in 1941. Space stations and satellites already use solar panel arrays for their power needs, but NASA abandoned the concept of stand-alone space solar after some study decades ago. The idea of building renewable-energy projects in space to […]
NASA astronaut Shane Kimbrough and European Space Agency astronaut Thomas Pesquet conducted a spacewalk Sunday — their second in the past week — to install new solar arrays that will provide a power boost to the space station. After facing “technical delays” during a spacewalk, NASA astronaut Shane Kimbrough and European Space Agency astronaut Thomas […]
A happy accident has resulted in the Solar Orbiter mission spying eruptions from the sun. These eruptions, called coronal mass ejections, blast out solar particles across the solar system and have the potential to disrupt technology if they reach Earth. These eruptions were detected by multiple instruments on the spacecraft during a close flyby of […]
Ever since Musk called fuel cells “staggeringly dumb,” there has been a fierce rivalry between lithium-ion and hydrogen backers The California Fuel Cell Partnership tallied 8,890 electric cars and 48 electric buses running on hydrogen batteries, which are refillable in minutes at any of 42 stations there. On the East Coast, the number of people […]
From virtual patient to electric planes, top emerging tech of 2020 The report identified the “top 10 emerging technologies” after experts whittled down scores of nominations to a select group of new developments with the potential to spur real progress. New Delhi: While scientists developed vaccines against Covid-19 in a record time this year, emerging […]
