NASA Loses Contact with MAVEN Spacecraft After 11 Years Orbiting Mars
NASA has lost communication with the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft, a critical asset in the study of the Red Planet’s atmosphere and one of three orbiters currently circling Mars. The agency announced Tuesday that contact was lost on Sunday, sparking an investigation into the anomaly.
The loss of contact occurred as MAVEN passed behind Mars from Earth’s perspective. According to NASA, telemetry indicated the spacecraft was functioning normally prior to this passage, but communications have not been re-established since it emerged. “The spacecraft and operations teams are investigating the anomaly to address the situation,” a NASA spokesperson stated. “More information will be shared once it becomes available.”
Despite the communication breakdown, NASA, in conjunction with operators at the Jet Propulsion Laboratory’s Deep Space Network in California, continues to attempt to locate and “ping” MAVEN along its predicted orbital path. This ongoing effort aims to pinpoint the cause of the issue and formulate a recovery plan.
MAVEN’s mission, launched November 18, 2013, from Cape Canaveral Air Force Station in Florida, has extended well beyond its original scope. Weighing 5,410 pounds at launch (1,784 pounds without fuel), the spacecraft began orbiting Mars on September 21, 2014, after a 442 million-mile journey. In 2022, the team implemented an “all-stellar” navigation system to conserve the spacecraft’s inertial measurement units. Despite operating “well past the end of prime mission,” NASA confirms MAVEN possesses sufficient propellant to continue orbiting through at least the end of the decade. Operational costs for the spacecraft totaled $22.6 million in 2024.
The primary objective of the MAVEN mission is to understand how Mars lost its atmosphere and liquid water over billions of years. Scientists believe that studying the planet’s upper atmosphere, ionosphere, and interactions with the Sun and solar wind will provide crucial insights into the Red Planet’s past habitability. Understanding this atmospheric loss is key to unraveling the history of Mars’ climate and potential for past life. As one analyst noted, “The data MAVEN has provided is invaluable for understanding planetary evolution.”
Beyond its scientific role, MAVEN also functions as a vital communications relay for NASA’s rovers on the Martian surface, including Curiosity, which landed in August 2012, and Perseverance, which arrived in February 2021. Other orbiters, such as the long-serving Mars Odyssey (orbiting since October 2001) and Mars Reconnaissance Orbiter (since March 2006), also provide this crucial relay service.
The Martian orbital landscape is increasingly populated, with four additional spacecraft from international space agencies currently in operation. These include the European Space Agency’s Mars Express (since December 2003), the ExoMars Trace Gas Orbiter (a collaboration between ESA and Russia’s Roscosmos, since October 2016), the United Arab Emirates Space Agency’s Mission Hope (since February 2021), and China’s Tianwen-1 (since February 2021).
Looking ahead, NASA is preparing for further Martian exploration. On November 13, a Blue Origin New Glenn rocket launched two NASA ESCAPADE satellites, destined to arrive at Mars in September 2027. This mission will utilize a longer trajectory than previous Mars endeavors.
The current situation with MAVEN underscores the inherent risks of deep space exploration, but also highlights the resilience and ingenuity of the teams working to unlock the secrets of the Red Planet. The ongoing investigation will be critical to determining the fate of this long-serving and valuable scientific asset.
