Anyone who’s ever lived along a coastline or been at sea knows the effects of tsunamis. And, they appreciate all the early warning they can get if one’s on the way. Now, NASA’s GNSS Upper Atmospheric Real-time Disaster and Alert Network (GUARDIAN) is using global navigation systems to measure the effect these ocean disturbances have on our atmosphere. The system’s measurements could provide a very effective early warning tool for people to get to higher ground in the path of a tsunami.

Accelerating the Green Transition
Earth observation has been essential in identifying and monitoring climate change. Satellite data form the baseline for effective European mitigation and adaptation strategies to support the Green Transition, the European Union to reach its goal of becoming carbon neutral by 2050, as well as its Green Deal.
Galileo Second Generation enters full development phase
The main procurements batch of Galileo Second Generation initiated last summer has been finalised, leaving the system ready for its In Orbit Validation development phase. Today, following the opening session of the European Navigation Conference (ENC), ESA Director of Navigation Javier Benedicto invited Thales Alenia Space (Italy), Airbus Defence and Space (Germany) and Thales Six GTS (France) to sign the respective contracts commencing System Engineering Support for the next generation of Europe’s navigation satellite system.
If You’re Going to Visit Venus, Why Not Include an Asteroid Flyby Too?
A recent study submitted to Acta Astronautica examines the prospect of designing a Venus mission flight plan that would involve visiting a nearby asteroid after performing a gravity assist maneuver at Venus but prior to final contact with the planet. The study was conducted by Vladislav Zubko, who is a researcher and PhD Candidate at the Space Research Institute of the Russian Academy of Science (RAS) and has experience studying potential flight plans to various planetary bodies throughout the solar system.
ESA is Testing How Iron Burns in Weightlessness
What happens when you burn iron in space? The European Space Agency is torching iron powder in microgravity, to find out. They aren’t doing it for the fun of it, but to understand something called “discrete burning.” It turns out that this process might enable more efficient iron-burning furnaces right here on Earth. It could eventually join other renewable energy sources as a way to combat the release of greenhouse gases in our atmosphere.
Here's How You Could Get Impossibly Large Galaxies in the Early Universe
One of the most interesting (and confounding) discoveries made by the James Webb Space Telescope (JWST) is the existence of “impossibly large galaxies.” As noted in a previous article, these galaxies existed during the “Cosmic Dawn,” the period that coincided with the end of the “Cosmic Dark Age” (roughly 1 billion years after the Big Bang). This period is believed to hold the answers to many cosmological mysteries, not the least of which is what the earliest galaxies in the Universe looked like. But after Webb obtained images of these primordial galaxies, astronomers noticed something perplexing.
