Was Venus once a good home for life? NASA missions aim to find out

Share The DAVINCI+ probe falls toward Venus, sampling the atmosphere as it goes, in an artist’s concept. NASA GSFC; CI LABS/MICHAEL LENTZ AND OTHERS Was Venus once a good home for life? NASA missions aim to find out Jun. 9, 2021 , 3:35 PM When NASA announced last week it would spend $1 billion developing two new missions to Venus the agency’s first visits in decades to Earth’s hothouse twin planetary scientists were elated, and not just because a long wait had ended. A dramatic shift in thinking about the planet over the past few years has made a visit even more enticing. Venus was once thought to have boiled off all its water almost as soon as it was born 4.5 billion years ago, turning into the parched, hostile world of today. But many scientists now think Venus might have kept expansive oceans for billions of years a nearly perfect setting for life.

Landmark study casts doubt on controversial theory linking melting Arctic to severe winter weather

Share A weaker, wavier jet stream allows Arctic air to spill south to midlatitudes. NASA/GODDARD SPACE FLIGHT CENTER SCIENTIFIC VISUALIZATION STUDIO Landmark study casts doubt on controversial theory linking melting Arctic to severe winter weather May. 12, 2021 , 12:10 PM Every time severe winter weather strikes the United States or Europe, reporters are fond of saying that global warming may be to blame. The paradox goes like this: As Arctic sea ice melts and the polar atmosphere warms, the swirling winds that confine cold Arctic air weaken, letting it spill farther south. But this idea, popularized a decade ago, has long faced skepticism from many atmospheric scientists, who found the proposed linkage unconvincing and saw little evidence of it in simulations of the climate.

NASA's new fleet of satellites will offer insights into the wild cards of climate change

Planned NASA satellites will measure the vertical motions that lead to towering storm clouds. SANTIAGO BORJA NASA’s new fleet of satellites will offer insights into the wild cards of climate change May. 5, 2021 , 11:15 AM NASA is about to announce its next generation of Earth-observing satellites. As soon as this month, it will lay out preliminary plans for a multibillion-dollar set of missions that will launch later this decade. This “Earth system observatory,” as NASA calls it, will offer insights into two long-standing wild cards of climate change clouds and aerosols while providing new details about the temperatures and chemistry of the planet’s changing surface. The satellite fleets also mark a revival for NASA’s earth science, which has languished over the past decade compared with exploration of Mars and other planets.
