  1. NASA-ISRO SAR (NISAR) satellite mission releases both L-band and S-band data. L-band is global coverage in new release on 20 July. S-band is for the Indian subcontinent and some additional areas, released on 15 July. See NASA press release with more details and “hummingbird” shape found in radar images of Antarctica nasa.gov/missions/nisar/us-ind . #NASA #ISRO #SAR #NISAR #Lband #Sband

  12. Flash droughts don't wait for the seasonal forecast. Across 41 events at 12 central-US sites (2016–2024), we've been disentangling whether atmospheric dryness (VPD) or root-zone soil moisture is the dominant stressor — the answer changes how early you can see one coming.

    NISAR's L-band radar is about to make root-zone moisture visible at scale, which makes this question answerable in near-real-time.

  17. Проклятие Бога Солнца: как потомки конкистадоров расплачиваются за грехи предков

    Многие инженерные решения выглядят единственным разумным вариантом в момент их принятия. Альтернативы кажутся слишком дорогими, сложными и непривычными. Горизонт планирования ограничен несколькими десятилетиями, тогда как проблемы могут проявиться через 100, а то и через 500 лет. Именно это происходит в Мехико: город проседает на сантиметры каждый месяц, а в наиболее пострадавших кварталах — на 50 сантиметров в год. Проблема заложена почти 500 лет назад, описана 100 лет назад — и она по-прежнему не решена. Трещины в дорогах, перекошенные здания, обрушения метро, водный кризис — все это тянется от одного решения, принятого испанскими конкистадорами в XVI веке. Давайте разберемся, как ошибки прошлого влияют на настоящее и к каким фундаментальным проблемам с окружающей нас инфраструктурой приводит смена технологий.

  20. NASA earth observation satellites have been shown to be able to locate the approximate positions of GPS jammers - typically within 3-6kms.

    Researchers looked at data from the Cyclone Global Navigation Satellite System (CYGNSS) and NASA-ISRO Synthetic Aperture Radar (NISAR), satellites to locate known GPS jammer sites (in Iran) and indicate how this information has potential usefulness for supporting the creation and distribution of warnings for aviation and maritime navigation that may be affected by GPS jammers. arstechnica.com/gadgets/2026/0
