Google-backed satellites for wildfire detection launch as smoke chokes US, Canada
Google-backed satellites for wildfire detection launch as smoke chokes US, Canada
谷歌支持的野火监测卫星发射升空，此时美加两国正深陷烟霾
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. 随着数百场野火产生的烟雾蔓延至加拿大和美国，谷歌支持的“FireSat”项目首批三颗运行卫星已成功发射入轨。这些卫星将在今年年底前投入使用，能够监测到美国、澳大利亚和欧洲境内即使是微小的火情。
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. 2026年7月7日，这些微型卫星搭乘SpaceX的“猎鹰9号”火箭从加利福尼亚州范登堡太空军基地发射升空，标志着由非营利组织“地球火灾联盟”（Earth Fire Alliance）管理的FireSat卫星星座正式进入“初始运行能力”阶段。经过三个月的测试期，这三颗卫星将开始积极向消防机构提供数据，并确保每天至少两次覆盖地球上所有易发生火灾的地区。
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. FireSat是首个专门为监测野火而建造的卫星星座，能够发现其他卫星可能遗漏的小型火点。这些卫星由总部位于加州的卫星制造商Muon Space设计，并获得了谷歌超过1500万美元的资金支持以用于初步部署。其他重要的财务支持者还包括承诺捐赠2600万美元的贝佐斯地球基金（Bezos Earth Fund）。
Each satellite is equipped with multispectral imaging that can peer through smoke and clouds and detect fires as small as five by five meters—about 16 by 16 feet. That capability was proven by a FireSat Protoflight satellite that launched in March 2025 and collected more than one million images, while showing it could detect low-intensity blazes invisible to existing satellites. 每颗卫星都配备了多光谱成像系统，能够穿透烟雾和云层，探测到小至5米乘5米（约16英尺乘16英尺）的火点。这一能力已由2025年3月发射的FireSat原型卫星得到验证，该卫星收集了超过一百万张图像，并证明其能够探测到现有卫星无法察觉的低强度火灾。
The Future of Wildfire Detection
野火监测的未来
The “early adopter” organizations that will start using FireSat data this year include fire agencies in California, Colorado, Australia, and Portugal. As more satellites launch, the FireSat program aims to provide the latest imagery anywhere in the world on an hourly basis by 2029. Such imagery would eventually become available every 20 minutes once the full constellation of more than 50 satellites is launched by the early 2030s. 今年将开始使用FireSat数据的“早期采用者”组织包括加利福尼亚州、科罗拉多州、澳大利亚和葡萄牙的消防机构。随着更多卫星的发射，FireSat项目计划到2029年实现每小时提供全球各地的最新影像。一旦到2030年代初发射超过50颗卫星的完整星座，此类影像最终将实现每20分钟更新一次。
Detection of small wildfires before they burn out of control could prove extremely helpful. The Earth Fire Alliance has projected that even an hourly revisit rate by the FireSat constellation could help save more than $1 billion in fire damage costs and prevent nearly 22 million tons of carbon emissions, along with protecting 3,500 homes and 1.3 million acres of land. 在小型野火失控前将其发现，其价值不言而喻。地球火灾联盟预计，即使FireSat星座仅能实现每小时一次的重访频率，也有助于节省超过10亿美元的火灾损失成本，防止近2200万吨碳排放，并保护3500所房屋和130万英亩土地。
To assist with that capability, Google Research plans to use the company’s AI models to compare operational FireSat data with historical images in order to accurately identify very small fires and to inform predictive modeling of wildfires. Google celebrated the launch of the first operational FireSat satellites by describing the event as “another tangible step forward in putting practical AI to work for climate resilience.” 为了辅助这一能力，谷歌研究院计划利用其人工智能模型，将FireSat的运行数据与历史图像进行比对，从而精准识别极小的火点，并为野火预测模型提供参考。谷歌在庆祝首批FireSat运行卫星发射时表示，这一事件是“将实用人工智能应用于气候韧性方面的又一实质性进展”。
The trouble with fires and climate change
火灾与气候变化的困境
But Silicon Valley’s rush to deploy newer AI models has also come with considerable climate costs that are linked to a worsening wildfire problem. Larger AI data centers require massive amounts of electricity that are often being met by new natural gas projects in the United States, which could collectively emit more than 129 million tons of greenhouse gases per year. 然而，硅谷竞相部署更新的人工智能模型也带来了巨大的气候代价，这与日益严重的野火问题息息相关。大型人工智能数据中心需要消耗海量电力，而这些电力往往由美国境内的新天然气项目提供，这些项目每年合计可能排放超过1.29亿吨温室气体。
Google has itself acknowledged the challenges of deploying enough clean energy projects to offset potential emissions from energy-hungry data centers, especially as its company-wide electricity usage grew by 37 percent in 2025. Google’s financial and technical support of AI-powered wildfire detection could prove incredibly helpful. But wildfire detection is just one of multiple elements necessary to prevent blazes from spiraling out of control—fire agencies also need enough resources to manage ecosystems through prescribed burns and to put out unwanted fires. 谷歌自身也承认，部署足够的清洁能源项目以抵消高能耗数据中心潜在排放量面临着挑战，尤其是在其公司整体用电量于2025年增长了37%的情况下。谷歌对人工智能野火监测的财务和技术支持固然非常有益，但野火监测只是防止火灾失控的多个必要环节之一——消防机构还需要足够的资源，通过计划烧除来管理生态系统，并扑灭不必要的火灾。
And their job has become increasingly challenging because of global warming. Traditional fire suppression has proven inadequate in the case of the wildfires that began spreading in Canada’s boreal forests this summer and has forced thousands of people in First Nations communities to escape the fast-moving blazes. The wildfires have also generated smothering smoke clouds across Canadian and US cities while inflicting hazardous air pollution upon more than 100 million people. 由于全球变暖，他们的工作变得愈发艰巨。事实证明，传统的灭火手段在应对今年夏天蔓延至加拿大北方森林的野火时显得力不从心，这些火灾迫使数千名原住民社区居民逃离迅速蔓延的火海。野火还导致加拿大和美国的城市上空笼罩着令人窒息的烟云，并使超过1亿人遭受危险的空气污染。
The wildfires in Canada’s boreal forests are burning with greater size and intensity because of climate change, as greenhouse gas emissions from human use of fossil fuels continue to drive global warming. Two of Canada’s most destructive wildfire seasons occurred in 2023 and 2025, and the last three fire seasons were among the 10 worst on record. 由于气候变化，人类使用化石燃料产生的温室气体排放持续推动全球变暖，加拿大北方森林的野火燃烧规模和强度都在增加。加拿大最具破坏性的两个野火季分别发生在2023年和2025年，过去三个火灾季均位列有记录以来最严重的十个火灾季之列。
“What is unfolding is what climate and forest scientists have been predicting for 30 years,” Werner Kurz, a retired senior research scientist at Natural Resources Canada, told The Atlantic. “That as the world gets hotter and drier, we are exposing forests to more and more risk, and the old strategies of fire suppression are simply being overwhelmed.” “目前正在发生的一切，正是气候和森林科学家们30年来一直预测的情况，”加拿大自然资源部退休高级研究科学家沃纳·库尔茨（Werner Kurz）告诉《大西洋月刊》，“随着世界变得越来越热、越来越干，森林正面临越来越大的风险，而旧有的灭火策略已完全无法应对。”
Fighting wildfires in mostly uninhabited forest regions requires fixed-wing air tankers and heavy-lift helicopters capable of dropping fire retardants on wildfires or transporting firefighting crews to the remote sites. But individual Canadian provinces usually bear the burden of buying or contracting for such firef 在大多无人居住的森林地区扑灭野火，需要固定翼空中加油机和重型直升机，以便向火场投放阻燃剂或将消防队员运送到偏远地区。然而，加拿大各省通常需要自行承担购买或租赁此类消防设备的重担。
