InSight mission to Mars Lands Nov. 26

Standard

After a successful launch in May 5, 2018 the Insight mission sent to Mars to explore Mars’ interior structure is planned to land on November 26, 2018. The interesting part is the mission landing will be monitored by two cube satellites that were launched with Insight and have been traveling on their own since the launch as show in the launch video below. The landing can be watched live on Nov. 26, 2018.

How Groundwater Extraction & Replenishing Causes Surface Deformation & Subsidence

Standard

Researchers at Caltech made the animations below which show the seasonal deformation and subsidence of Earth’s surface, respectively,  as a result of groundwater extraction and refilling. This occurs when soil and earth layers are compacted and undergo subsidence due to the decrease of upward hydrostatic pressure balancing the weight of the layers.

Surface deformation and subsidence of Earth’s surface is measured using Interferometric Synthetic Aperture Radar (ISAR). ISAR is also used for natural hazard assessment. This includes applications to regions of volcanic, tectonic (e.g. faults and mountains), and construction activities.
