Climate damage caused by growing space tourism needs urgent mitigation
Published today in the journal Earth's Future, researchers from UCL, the University of Cambridge and Massachusetts Institute of Technology (MIT) used a 3D model to explore the impact of rocket launches and re-entry in 2019, and the impact of projected space tourism scenarios based on the recent billionaire space race.
Multiple lab analyses of Antarctic minerals offer a better understanding of Mars
Results of multiple and complementary lab analyses of minerals found in samples of material from Antarctica could give scientists a better understanding of the surface and subsurface environment of Mars, and indicate locations of potentially habitable subsurface locations, says a new paper by Planetary Science Institute Research Scientist Elizabeth C. Sklute.
Image: Hubble captures a galactic menagerie

What is causing record floods and heatwaves in China?
Record floods in southern China this month displaced more than half a million people, while searing heat buckled roads in other parts of the country.
'Deepest shipwreck': US WWII ship found off Philippines
A US navy destroyer sunk during World War II has been found nearly 7,000 meters (23,000 feet) below sea level off the Philippines, making it the world's deepest shipwreck ever located, an American exploration team said.
Oceans saved us, now we can return the favor
Humanity must heal oceans made sick by climate change, pollution and overfishing in order to rescue marine life and save ourselves, experts warned ahead of a major UN conference opening Monday in Lisbon.
NASA asteroid mission on hold due to late software delivery
NASA put an asteroid mission on hold Friday, blaming the late delivery of its own navigation software.
Biofinder advances detection of extraterrestrial life
An innovative scientific instrument, the Compact Color Biofinder, developed by a team of University of Hawai'i at Mānoa researchers, may change the game in the search for signs of extraterrestrial life.
Investigating the dynamics that reshape permafrost environments
When permafrost thaws, water can flow more quickly through the ground, creating a complex subsurface flow system. Researchers at the Barrow Environmental Observatory in Alaska gained insight into this process by taking daily measurements of the electrical resistivity of the ground. The results show that vegetation and the snowpack that accumulates on the vegetation in winter control the...
New study offers insight into past—and future—of west-side wildfires
When the 2020 Labor Day Fires torched more than 300,000 hectares over the span of two weeks in parts of western Oregon and Washington, they devastated communities and put the threat of west-side fires squarely into focus. A new study led by the USDA Forest Service's Pacific Northwest Research Station examines the context surrounding the fires and offers insight into the historical role of large,...
Infrastructure, hunting and climate change linked to huge migratory bird declines
Migratory birds are declining globally because of the way that humans have modified the landscape over recent decades—according to new research from the University of East Anglia.
