  • Tracking Spring Flooding
    Rivers swelled in southern Russia and northern Kazakhstan in April 2024 following heavy rain and rapid snowmelt. This image shows Orenburg on April 13, the day river levels peaked. This scene was acquired by the OLI-2 (Operational Land Imager) on Landsat 9.

  • Sols 4166-4167: A Garden Full of Rocks April 24, 2024
    Earth planning date: Wednesday April 24, 2024 Here on Earth (in Toronto, specifically), it’s a very typical April which can’t quite make up its mind about whether or not it wants to be spring. On Mars (in Gale Crater), we’re well into spring, and Curiosity is enjoying the (relatively) warmer weather. As the days get […]
