NASA Investigates MAVEN Spacecraft Signal Loss at Mars

NASA Investigates MAVEN Spacecraft Signal Loss at Mars

NASA's MAVEN spacecraft, which is orbiting Mars, experienced a loss of signal with Earth-based ground stations on December 6. Prior to the signal loss, telemetry indicated that all subsystems were functioning normally. The signal was lost when MAVEN orbited behind Mars, and it did not re-establish contact upon re-emerging. NASA's Deep Space Network is currently working with the spacecraft and operations teams to investigate the anomaly and restore communication. MAVEN, launched in 2013, has been studying Mars' upper atmosphere and its interactions with solar wind to understand atmospheric loss.

NASA Investigates MAVEN Spacecraft Signal Loss After Mars Orbit

NASA Investigates MAVEN Spacecraft Signal Loss After Mars Orbit

NASA's MAVEN spacecraft, which has been orbiting Mars since 2014, experienced a loss of signal with Earth on December 6. Prior to the signal loss, telemetry indicated that all subsystems were functioning normally. The spacecraft lost contact after moving behind Mars, and upon re-emerging, the Deep Space Network failed to detect a signal. NASA teams are currently investigating the anomaly to determine the cause and address the issue. MAVEN's mission is to study Mars' upper atmosphere and its interactions with the Sun and solar wind, providing insights into the planet's atmospheric history and climate. The spacecraft also serves as a communications relay for Martian rovers.

NASA's Perseverance Rover Finds Evidence of Ancient Tropical Rainfall on Mars

NASA's Perseverance Rover Finds Evidence of Ancient Tropical Rainfall on Mars

NASA's Perseverance Rover has discovered fragments of bleached clay on Mars, suggesting the planet once experienced tropical rainfall. Researchers from Purdue University analyzed these fragments, which indicate Mars was warm and wet for millions of years, similar to Earth's tropical regions. The findings, based on the rover's exploration of the Jezero Crater, provide further evidence that Mars had conditions suitable for life. The presence of kaolinite, a clay mineral formed under tropical conditions, supports the theory of a once-habitable Martian environment.
