I wish you a good read! :)
Recent volcanic activity has been observed on Venus for the first time
🌋 Scientists made the discovery after poring over archival radar images of Venus taken more than 30 years ago, in the 1990s, by NASA’s Magellan mission.
🌋 The images revealed a volcanic vent changing shape and increasing significantly in size in less than a year
📰 The search and its conclusions are described in a new study published in the journal Science: Surface changes observed on a Venusian volcano during the Magellan mission
Landsat 9 Collection 2 Level-3 products are now available
🛰️ The Landsat 9 Dynamic Surface Water Extent (DSWE) and Fractional Snow Cover Area (fSCA) science products are now available to download from EarthExplorer and the Commercial Cloud.
Sentinel Hub webinar: Arctic Wildfires - What can (and can’t) we know from satellites?
🔥 Satellite data are extremely useful in monitoring wildfire activity, including in the Arctic.
🔥 You will explore, whether and how this can actually be seen through the EO data.
🔥 You will also learn about the role of climate change in the occurrence of these fires and how this process might further drive climate change.
Brazil's president is negotiating to build a new satellite to monitor deforestation in the Amazon
🛰️ The agreement provides that the satellite will be binational and without military use.
🛰️ The main news is that the new generation of satellites will have radars, something that did not exist in previous projects.

Announcement of opportunity for SAOCOM
👩🏾💻 ESA is launching an opportunity for the international scientific community to access data from SAOCOM Mission for science and EO-base applications development.

Scientists sound the alarm over a growing trash problem in space
🛰️ Currently, 9,000 active satellites are in orbit—a number expected to grow to over 60,000 by 2030 and 100 trillion objects are currently circling the planet.
🛰️ The 100 trillion figure includes everything from spent boosters and stray bolts to metal flecks and floating paint chips that went along with launching all of that hardware.

Week's recommended reading
In this paper, the authors recognized three major research themes regarding the characteristics of land use and land cover (LULC) data, different simulated scenarios of LULC changes, and the role of future scenarios for both LULC and landslide susceptibility.
