International SWOT Mission Can Improve Flood Prediction
Thursday, 09 May 2024 20:41
A partnership between NASA and the French space agency, the satellite is poised to help improve forecasts of where and when flooding will occur in Earth's rivers, lakes, and reservoirs.
Rivers, lakes, and reservoirs are like our planet's arteries, carrying life-sustaining water in interconnected networks. When Earth's water cycle runs too fast, flooding can result, threatening lives and propert NASA Advances Climate Research with New Earth System Explorers Program Proposals
Thursday, 09 May 2024 20:41
NASA has selected four new proposals for concept studies as part of its Earth System Explorers Program, aimed at enhancing our understanding of key Earth science areas such as greenhouse gases, the ozone layer, ocean currents, and global ice changes.
These investigations align with recommendations from the 2017 Decadal Survey by the National Academies of Sciences, Engineering, and Medicine Ozone's influence on exoplanetary climate dynamics highlighted in new research

In a significant study led by Dr. Assaf Hochman from the Fredy and Nadine Herrmann Institute of Earth Sciences at The Hebrew University of Jerusalem, new insights have been unveiled into the atmospheric dynamics of Earth-like exoplanets, with a focus on ozone's role in shaping planetary climates. This research represents a major step in understanding potentially habitable worlds beyond our solar Where space weather originates

The Virtual Space Weather Modelling Centre, through a collaborative effort, has developed a simulation that visualizes the initiation of space weather. The model demonstrates the emergence of a flux rope from the Sun's magnetic field, which may carry millions of tons of plasma into space during a Coronal Mass Ejection (CME).

CesiumAstro, known for its advanced phased array communications technology for space and airborne systems, announced its selection by Rocket Lab (Nasdaq: RKLB) to supply its Vireo active electronically scanned array (AESA) radio frequency (RF) communications payload for integration into 18 space vehicles (SVs) supporting the Space Development Agency's (SDA) Tranche 2 Transport Layer (T2TL). NASA watchdog report: 100+ cracks on heat shield biggest threat to human moon mission
Thursday, 09 May 2024 20:18
The damage to the Orion capsule from the Artemis I mission is already top of mind for NASA as it works to make the Artemis II mission safe for humans. But a new agency report has revealed the extent of the problem, including scores of cracks in Orion's critical heat shield.
The report from NASA's Office of Inspector General outlined six issues that need NASA's attention, with the heat shield damage found after the uncrewed Artemis I test mission in late 2022 at the top of the list.
NASA found more than 100 places on the heat shield where what's known as the char layer ended up "cracking and breaking off the spacecraft in fragments that created a trail of debris rather than melting away as designed," the report reads. Images released for the first time in the report showed the extent of the damage.
It notes that the reentry speeds coming in from a lunar trajectory reach nearly 25,000 mph, which is about 40% faster than what astronauts face when returning from low-Earth orbit in SpaceX's Crew Dragon.

The upcoming launch of the Φsat-2 mission is a prime example of the pioneering work that ESA does in the field of AI in Earth observation.
But when it comes to AI, hopes and fears abound in equal measure. In this interview, ESA’s Rochelle Schneider sets the record straight on how this transformational technology is improving access to crucial information on the state and future of our planet.
