Powerful New US-Indian Satellite Will Track Earth’s Changing Surface

NeRD

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The NISAR mission will help researchers get a better understanding of how Earth’s surface changes over time, including in the lead-up to volcanic eruptions like the one pictured, at Mount Redoubt in southern Alaska in April 2009. R.G. McGimsey/AVO/USGS Data from NISAR will improve our understanding of such phenomena as earthquakes, volcanoes, and landslides, as well as damage to infrastructure. We don’t always notice it, but much of Earth’s surface is in constant motion. Scientists have used satellites and…

Ongoing Venus Volcanic Activity Discovered With NASA’s Magellan Data

NeRD

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This computer-generated 3D model of Venus’ surface shows the volcano Sif Mons, which is exhibiting signs of ongoing activity. Using data from NASA’s Magellan mission, Italian researchers detected evidence of an eruption while the spacecraft orbited the planet in the early 1990s. NASA/JPL-Caltech An analysis of data from Magellan’s radar finds two volcanoes erupted in the early 1990s. This adds to the 2023 discovery of a different active volcano in Magellan data. Direct geological evidence of recent volcanic activity…
