Tonga underwater volcano disrupted satellite signals halfway around the world
Wednesday, 24 May 2023 10:02
An international team has used satellite- and ground-based ionospheric observations to demonstrate that an air pressure wave triggered by volcanic eruptions could produce an equatorial plasma bubble (EPB) in the ionosphere, severely disrupting satellite-based communications. Their findings were published in the journal Scientific Reports.
The ionosphere is the region of the Earth's upper a Planet announces AI Partnerships at GEOINT 2023

Planet Labs PBC (NYSE: PL), a leading provider of daily data and insights about Earth, has announced new strategic partnerships with artificial intelligence (AI) analytics providers at the U.S. Geospatial Intelligence Foundation's 2023 GEOINT Symposium. These companies' AI-powered analytics enable object detection and classification services on top of Planet's high-frequency, medium- and high-re Mars rover Zhurong finds evidence of water at red planet's low latitudes
Wednesday, 24 May 2023 10:02
China's Mars rover Zhurong has provided key observational evidence of liquid water at low Martian latitudes, the warmest regions on the red planet, according to a new study published in the journal Science Advances this week.
Previous studies found evidence of a large amount of liquid water on early Mars, but dramatic climate changes led to very low pressure and water vapor content, making MAHLI works the night shift: Sols 3837-3838

Earth planning date: Monday, May 22, 2023- Curiosity successfully wrapped up the "Ubajara" drill campaign over the weekend with some imaging of the drill tailings. This Monday, we are planning two sols (Mars days) of activities to finish up at Ubajara before driving off in the coming sols. Most targeted science today is focused on bedrock target "Apetina," which is situated on the same block as Light shining through a wall experiment searches for dark matter

A mysterious signal is being sent by ESA’s ExoMars Trace Gas Orbiter on 24 May, a spacecraft orbiting the Red Planet looking for evidence of possible biological or geological activity.
As part of the global 'A Sign In Space' art project, it will strike huge antennas dotted around the globe; the Green Bank Telescope (West Virginia), the Medicina Radio Astronomical Station (Italy) and the Allen Telescope Array (California).
Early tests were conducted to ensure the feasibility of the endeavour and allow the ground-based observatories to fine tune their systems to be ready for the public event.

Satellites provide crucial insights into Arctic amplification
Wednesday, 24 May 2023 06:45
The Arctic, once again at the forefront of climate change, is experiencing disproportionately higher temperature increases compared to the rest of the planet, triggering a series of cascading effects known as Arctic amplification. As concerns continue to grow, satellites developed by ESA have become indispensable tools in understanding and addressing the complex dynamics at play and the far-reaching consequences for the environment and human societies.
