Dr. Eric J. Fielding, PhDGreat news, the NASA SPHEREx satellite has started talking to the ground stations, so it is orbiting and working well. <a href="https://blogs.nasa.gov/spherex/2025/03/12/signal-acquired-nasas-spherex-begins-science-mission/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://blogs.nasa.gov/spherex/2025/03/12/signal-acquired-nasas-spherex-begins-science-mission/</a> <a href="https://mastodon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NASA</a> <a href="https://mastodon.social/tags/NASA_JPL" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NASA_JPL</a> <a href="https://mastodon.social/tags/SPHEREx" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SPHEREx</a>

Dr. Eric J. Fielding, PhDNASA Radar Imagery Reveals Details About Los Angeles-Area Landslides. Landslides on Palos Verdes peninsula have been moving rapidly in last two years. NASA airborne radar called UAVSAR flies on piloted NASA planes and measures displacements of the ground surface using InSAR analysis. We requested flights in three directions to map motion of landslides on the Palos Verdes peninsula next to Los Angeles. <a href="https://mastodon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NASA</a> <a href="https://mastodon.social/tags/NASA_JPL" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NASA_JPL</a> <a href="https://mastodon.social/tags/InSAR" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#InSAR</a> <a href="https://mastodon.social/tags/radar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#radar</a> <a href="https://mastodon.social/tags/landslides" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#landslides</a> <a href="https://www.jpl.nasa.gov/news/nasa-radar-imagery-reveals-details-about-los-angeles-area-landslides/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.jpl.nasa.gov/news/nasa-radar-imagery-reveals-details-about-los-angeles-area-landslides/</a>
