洛杉矶郊外的伊顿山火肆虐,摧毁了4627座建筑物,造成人员伤亡。NASA的飞机搭载仪器拍摄了火灾区域的图像,显示火灾逼近了NASA的喷气推进实验室(JPL),该实验室曾因火灾威胁而关闭。火灾烧毁了14117英亩土地,并对当地社区造成严重影响,许多JPL员工失去了家园。高温干燥的夏季、干燥的秋季以及强风共同导致了这场火灾,使得植被如同引火物般迅速燃烧。虽然JPL实验室幸免于难,但其员工社区遭受了重创。

🔥 伊顿山火在洛杉矶郊外爆发,摧毁了4627座建筑物,并造成人员伤亡,火灾面积达14117英亩。

🛰️ NASA的AVIRIS-3仪器拍摄的图像显示,火灾距离JPL仅约1公里,该实验室因火灾威胁而关闭,JPL负责包括旅行者号、火星探测器等重要任务。

🌡️ 高温干燥的夏季、干燥的秋季和强风是导致火灾迅速蔓延的主要原因,使得植被易燃,火势难以控制。

🏘️ 虽然JPL实验室未受火灾影响,但超过150名JPL员工失去了家园,许多人仍然流离失所。

Extreme wildfire is a driverless car. And it veered close to a major NASA center.

After erupting in wooded hills outside of Los Angeles' community of Altadena, the Eaton Fire — one of the damaging conflagrations impacting the region — catastrophically burned through homes and businesses, destroying 4,627 structures as of Jan. 15. The catastrophe has injured firefighters and taken lives. A NASA instrument, riding in an airplane, has captured a stark view of the burned area — and reveals how close it came to NASA's legendary Jet Propulsion Laboratory.

The lab closed on Jan. 8 as the area was evacuated during critical fire conditions. It's responsible for building and leading such missions as Voyager, the Mars rovers, and endeavors around other worlds.

The view below shows the impacts as of Jan. 11, when the fire had burned 14,117 acres. You're seeing an image captured by NASA's AVIRIS-3 instrument, or Airborne Visible/Infrared Imaging Spectrometer-3, which flies aboard high-altitude aircraft on Earth observation missions.

- The impacted neighborhoods, with charred trees and burned buildings in Altadena and portions of adjacent communities, are shown in dark brown.

- The burned wildland areas, where the fire (the cause of which is under investigation) started, appear in orange.

As the image above shows, fire came within about 1 kilometer, or 0.6 miles, of JPL.

Conditions were ripe for flames. A notably hot summer parched vegetation — July 2024 was California's hottest month on record — combined with a near-record dry fall and then a potent windstorm to drive fire and far-traveling embers into urban areas.

With vegetation turned to kindling, the flames couldn't be stopped.

The JPL campus has so far remained unscathed. But not so its employees.

"Thankfully, the laboratory remains untouched by fire due to the brave dedication of our first responders," the center recently posted online. "But our community has been seriously impacted with over 150 JPLers who have lost their homes, and many more remain displaced."
