ESA’s Biomass on track to target forests
Monday, 15 November 2021 13:20
With more than 100 global leaders at COP26 having pledged to halt and reverse deforestation and land degradation by the end of the decade to help address the climate crisis, the health of the world’s forests is high on the political agenda. ESA’s Biomass mission will soon play a key role in delivering novel information about the of the state of our forests, how they are changing over time, and advance our knowledge of the carbon cycle. With launch scheduled for 2023, the mission is now in its last phases of development, having recently passed several key milestones.

Feeling the heat: Fusion reactors used to test spacecraft heat shields
Sunday, 14 November 2021 10:30
Spacecraft have long used heat shields for protection during entry into planetary atmospheres. Future missions to the outer solar system will need more sophisticated materials than currently exist. The extreme heating conditions needed to study new shield materials are, however, very difficult to achieve experimentally on Earth.
Scientists working at the DIII-D National Fusion Facility at NOAA's next-gen weather satellite, built by Lockheed Martin, moves closer to launch
Sunday, 14 November 2021 10:30
Today, the next-generation Geostationary Operational Environmental Satellite (GOES)-T successfully arrived at Kennedy Space Center, Florida, to begin launch preparations. It is the third of four satellites in the National Oceanic and Atmospheric Administration (NOAA)'s GOES-R weather satellite series built by Lockheed Martin [NYSE: LMT] in Littleton, Colorado.
GOES-T will help NOAA provide Unveiling the steady progress toward fusion energy gain
Sunday, 14 November 2021 10:30
The march towards fusion energy gain, required for commercial fusion energy, is not always visible. Progress occurs in fits and starts through experiments in national laboratories, universities, and more recently at private companies.
Sam Wurzel, a Technology-to-Market Advisor at the Advanced Research Projects Agency-Energy (ARPA-E), details and highlights this progress over the last 60 ye Researchers at the brink of fusion ignition at national ignition facility
Sunday, 14 November 2021 10:30
After decades of inertial confinement fusion research, a record yield of more than 1.3 megajoules (MJ) from fusion reactions was achieved in the laboratory for the first time during an experiment at Lawrence Livermore National Laboratory's (LLNL) National Ignition Facility (NIF) on Aug. 8, 2021. These results mark an 8-fold improvement over experiments conducted in spring 2021 and a 25-fold incr Integrating hot cores and cool edges in fusion reactors
Sunday, 14 November 2021 10:30
Future fusion reactors have a conundrum: maintain a plasma core that is hotter than the surface of the sun without melting the walls that contain the plasma. Fusion scientists refer to this challenge as "core-edge integration."
Researchers working at the DIII-D National Fusion Facility at General Atomics have recently tackled this problem in two ways: the first aims to make the fusion core
