Big cities are sinking in the US. Is yours one?
- A recent study revealed that all major US cities are sinking due to groundwater extraction and other factors, impacting 34 million people.
- As aquifers are depleted without replenishment, the land sinks causing infrastructure integrity issues over time.
- The sinking rate ranges from 2 to 10 millimeters annually, with Houston sinking the fastest among US cities.
- Unequal sinking poses risks to buildings and roads, especially in densely populated urban cores.
- Texas cities like Houston, Dallas, and Forth Worth are particularly affected, with 80% of sinking attributed to groundwater extraction.
- Oil and gas extraction, glacial legacy, and building weight also contribute to land subsidence in cities.
- Mitigation strategies suggested include groundwater management, resilient infrastructure planning, and retrofitting buildings in high-risk areas.
- Long-term monitoring and adaptation are necessary to address the sinking issue in urban centers.
- The study urges proactive measures to combat sinking cities and emphasizes the importance of immediate responses and solutions.
- Groundwater extraction and various factors are causing the sinking of major US cities, urging the need for monitoring and mitigation strategies.

Intuitive Machines’ CEO points to issues that prevented upright touchdown during IM-2 Moon landing
- Intuitive Machines’ CEO, Steve Altemus, discussed issues that prevented the Nova-C lander from an upright touchdown during the IM-2 Moon landing on March 6, 2025.
- The identified issues included laser altimeter interference, challenging terrain and lighting effects, and crater recognition tuning.
- Adjustments are being made for the upcoming IM-3 mission to improve landing systems, such as adding dissimilar and redundant altimeters, incorporating additional sensors, and enhancing navigation capabilities.
- The IM-3 mission, scheduled for the first half of 2026, was selected by NASA with a firm fixed-price contract valued at $77.5 million and will carry four NASA science payloads to the Moon's Reiner Gamma region.
- This mission includes small rovers like Lunar Vertext (Lvx) and Cooperative Autonomous Distributed Robotic Explorers (CADRE), as well as a lunar data relay satellite to support NASA's Near Space Network Services.
- Intuitive Machines reported first quarter revenue of $62.5 million, attributed to progress milestones on the lunar terrain vehicle proposal and payments from the IM-2 mission.
- The company is competing for NASA's Lunar Terrain Vehicle program, with the final proposals expected to be submitted in July and an award anticipated in November.
- The LTV's procurement is part of Intuitive Machines' Moon-Mars strategy, aiming to advance autonomous mobility technology for future space exploration missions.
- NASA plans to award only one contractor for the LTV demonstration mission, with Intuitive Machines competing against Lunar Outpost and Venturi Astrolab for the task order.
- The company remains confident in progressing with the LTV procurement despite potential changes in the Artemis program, emphasizing the importance of autonomous mobility in space exploration.
