NASA’s Jet Propulsion Laboratory Faces Multiple Challenges Amid Wildfire Closure

The wildfires ravaging the Los Angeles region of California have not only severely threatened the safety and property of local residents but have also forced the closure of a critical institution in the U.S. aerospace field—the Jet Propulsion Laboratory (JPL), an important facility under NASA. Multiple U.S. media outlets lamented that what was supposed to be a moment of glory for American aerospace at the start of 2025 has been overshadowed by the challenges faced by JPL.

Two Key Space Facilities at Risk

According to the U.S. website “Space,” wildfires are an ever-present danger in California. They usually remain confined to the foothills of the San Gabriel Mountains and rarely spread to the densely populated Pasadena area. However, the region experienced unusually dry conditions late last year, with only 0.1 inches of rainfall in the Los Angeles area. Coupled with strong winds generated by an eastern high-pressure system, this created the worst-case scenario for the rapid spread of wildfires once ignited.

The cause of the Eaton Fire, which threatens JPL, remains unclear. However, it quickly spread southeastward, putting JPL in its path. Flames came as close as 600 meters to JPL’s facilities, directly threatening the ground control centers for the Mars rovers “Curiosity” and “Perseverance.” Fortunately, a change in wind direction prevented the fire from reaching JPL, but the blaze remains uncontrolled, leaving JPL vulnerable if winds shift again.

JPL had already announced its closure and evacuation. On January 8, JPL Director Laurie Leshin stated on social media platform X: “JPL is closed, with access restricted to emergency personnel. While the lab has not sustained direct fire damage (though there is some wind damage), the fire is alarmingly close. Hundreds of employees have been forced to evacuate their homes, and many have lost their residences.”

Critical JPL facilities and lab hardware have been relocated and safeguarded, and deep space network operations traditionally conducted at JPL have been shifted to backup centers.

JPL is not the only research institution threatened by wildfires. The nearby Mount Wilson Observatory has also been surrounded by fires. This historic observatory, where Edwin Hubble used a 100-inch telescope to discover galaxies beyond the Milky Way and prove the universe’s expansion, has already lost one of its buildings to the flames.

According to the “Space” news website, while the potential hardware losses at JPL and Mount Wilson Observatory are regrettable, the greater concern is the potential loss of personnel. The report emphasized that “JPL’s 60 years of success is due to its 5,500 exceptional employees. They chose JPL over more lucrative private-sector opportunities because they wanted to participate in the grand adventure of exploring the solar system.” The wildfire has caused significant property losses for JPL staff, with over 150 people reportedly losing their homes. JPL has instructed employees to work from home until January 17 unless absolutely necessary to access the lab.

The Importance of JPL

The “Space” website highlights that JPL is one of NASA’s primary centers for space and Earth science missions, managed by the California Institute of Technology. Its history dates back to World War II, and notable figures like Qian Xuesen were among its founders. Over decades, JPL has specialized in interstellar unmanned exploration, developing and launching dozens of spacecraft.

Some of JPL’s notable achievements include the “Voyager 1” and “Voyager 2” probes exploring the outer solar system, the “Surveyor 1” lunar lander, which demonstrated the safety of landing humans on the Moon, the “Europa Clipper” mission to investigate Jupiter’s moon Europa, and the “Curiosity” and “Perseverance” Mars rovers. JPL is also the lead agency for NASA’s Mars Sample Return mission.

Despite being called a “laboratory,” JPL is a massive research base spanning 168 acres. It houses facilities for assembling, testing, and operating spacecraft, including two large cleanrooms for planetary probe construction and sterilization, a mission control center for monitoring planetary missions, and numerous buildings accommodating engineering and scientific teams responsible for NASA’s planetary exploration missions.

Future Challenges

Although JPL boasts a glorious history, it has faced significant challenges in recent years. According to the “Space” website, U.S. Congress has repeatedly reduced funding for basic research to allocate resources elsewhere. For example, NASA’s 2024 budget of $24.875 billion is 2% lower than 2023’s and 8.5% below the requested amount, marking the largest funding gap since 1992. This budget shortfall has hit JPL’s Mars Sample Return mission the hardest.

Originally planned to return Martian rock and soil samples to Earth by 2033, this mission was prioritized by NASA in 2022. Initial estimates put its cost at $5–7 billion, but independent review boards suggested the total could exceed $11 billion and might not be completed until after 2040, potentially lagging behind China. As a result, NASA allocated only $300 million to the project in 2024, effectively shelving it.

Due to dissatisfaction with JPL’s approach to the Mars Sample Return mission, NASA sought innovative, cost-effective alternatives from other U.S. research institutions, private companies, and academia in mid-2024.

On January 8, NASA Administrator Bill Nelson announced at a press conference that two potential solutions for the mission have now been identified.
