To address a rapidly changing space operating environment and ensure its preservation for generations to come, NASA released the first part of its integrated Space Sustainability Strategy, on Tuesday advancing the agency’s role as a global leader on this crucial issue. “The release of this strategy marks true progress for NASA on space sustainability,” said […]

Amid a site teeming with new and young stars lies an intricate substructure. A team of astronomers has used NASA’s James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation Ursa Major, this galaxy is relatively compact in size but hosts a frenzy of star […]

By Rod Fujita and Kristin Kleisner  To mitigate climate change, sea level rise, and other environmental problems, some experts are looking to nature-based solutions. But which solutions are the most impactful when it comes to sequestering carbon? And what do we still need to learn to improve our scientific understanding of nature-based solutions?   We co-authored […]

This past August, in southern Ecuador amidst dense mangrove forests, scientists were at work. As I followed in her footsteps, Julie Shahan, a Stanford University Ph.D. student, navigated the challenging terrain, burdened by the large 25-pound piece of equipment on her back. This equipment, a gas analyzer, collects measurements to unlock the secrets of soil […]

By Christopher Cusack (EDF) and Cooper Van Vranken (Ocean Data Network) In the early hours of October 25, 2023, Hurricane Otis made landfall near Acapulco, Mexico, with peak winds of 165 mph wreaking havoc on communities in its path. Normally, people would have had a chance to prepare but just the day before, the consensus […]

We’re seeing the impacts of climate change in real time. There is an urgent need to reduce greenhouse gases (GHGs) in the atmosphere to avoid more catastrophic climate change impacts. This will require both reductions in GHG emissions and the removal of GHGs from the atmosphere. In recent years, this need has driven interest in […]

By Jacqui Vogel (EDF) and Dr. Sarah Glaser (WWF) Oceans are under immense threat from climate change. Around the world, oceanographic changes like melting sea ice, warming waters, sea level rise and shifting fish populations make access to marine resources more uncertain and less secure. Climate change threatens to disrupt the communities, supply chains and […]

The world is gathered in Dubai for the 28th Conference of the Parties under the United Nations Framework for Climate Change Convention, otherwise known as COP28. Over a two-week span, government delegations come together to negotiate what actions the world needs to take to achieve a future under 1.5 degrees. This will set the tone […]

NASA has selected four small explorer missions to conduct concept studies.

September 2023 Each month, NASA’s Planetary Defense Coordination Office releases a monthly update featuring the most recent figures on NASA’s planetary defense efforts, near-Earth object close approaches, and other timely facts about comets and asteroids that could pose an impact hazard with Earth. Here is the what we’ve found for September.
