Google-backed satellites for wildfire detection launch as smoke chokes US, Canada
摘要
由谷歌支持的FireSat项目首批三颗业务卫星成功发射入轨，将开始提供野火探测服务，能够在美国、澳大利亚和欧洲识别小型火灾。这三颗微型卫星于2026年7月7日由SpaceX猎鹰9号火箭从加州范登堡太空军基地发射升空，标志着非营利组织地球火联盟管理的FireSat星座进入“初始运行能力”阶段。经过三个月测试后，卫星将开始向消防机构提供数据，每天至少两次覆盖地球
As smoke from hundreds of burning wildfires spread across Canada and the United States, the first three operational satellites in the Google-backed FireSat program successfully launched into orbit. The satellites will begin providing wildfire detection capable of spotting even small fires in the United States, Australia, and Europe before the end of the year.
The launch of the microsatellites aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California on July 7, 2026 marks a transition to “initial operational capability” for the FireSat constellation managed by the nonprofit Earth Fire Alliance. After a three-month testing period, the three satellites will begin actively providing data to fire agencies while covering every fire-prone region on Earth at least twice per day.
FireSat represents the first satellite constellation purpose-built for detecting wildfires, including spotting smaller fires that other satellites may miss. The satellites were designed by California-based satellite manufacturer Muon Space and have received over $15 million from Google to support initial deployment. Other notable financial supporters include the Bezos Earth Fund that committed $26 million.
