The 12-year-old Mars probe is completely out of touch, NASA announces that Maven's mission is over.

According to the IT House, on June 4th, the National Aeronautics and Space Administration (NASA) of the United States is about to bid farewell to one of the outstanding Mars orbit detectors.

After months of repeated attempts to reconnect to the Mars atmosphere with the Volatile Evolution Explorer (MAVEN), NASA officially declared the Red Planet Explorer mission closed. The NASA Deep Space Monitoring Network received the last signal from MAVEN on December 6, after which the solar detector ran to the back of Mars and the communication was blocked by stars. According to a report released by the NASA Accident Review Committee in February this year, the telemetry data indicated that, after the launch of the probe from the other side of Mars, the equipment was automatically cut into a safety mode and rolled at an uncontrollable rotational position, eventually leading to the depletion of electricity.

NASA issued an announcement that all subsequent attempts to contact MAVEN have failed. On June 3, NASA officials held a press conference in which they declared the MAVEN mission to be over. The specific cause of the Detector ' s failure on the back of Mars is still under investigation.

MAVEN was retired and completed its scientific career in Mars exploration for more than 10 years. The probe was launched in November 2013 by the Joint Launch Coalition ' s Atlas-5 carrier rocket and entered Mars orbit 10 months later.

MAVEN Principal Researcher Shannon Curry evaluated it at the online meeting on Wednesday as "the most outstanding Mars exploration mission in history." The project manager, Mike Morrow, highly praises the R & D team, saying, "The mission is over and we are lost."

Curly shares this sentiment, but focuses on taking stock of many of the scientific results created by the probe: “All the team members are disappointed, but at the same time we are proud of the scientific results of the past decade.” She praised MAVEN as the “top-of-the-board observation device for the study of atmospheric flight in the whole solar system”.

According to Morrow, the FRC determined that the detection device had been completely out of power at an approximate rate within hours of last December's failure, “the interruption of the power supply eventually caused the communication system to fail and the detector to be completely unrepairable”, and added that “the accident investigation team is still digging into the underlying causes of the failure”.

According to information from the IT House, the MAVEN mission was scheduled to be in orbit for only one Earth year, and the mission was extended several times, with an additional 10 years of service, owing to the steady and excellent condition of the equipment. Only two NASA detectors remain in active service in Mars orbit after the MAVEN crash: the Mars Odyssey, which was launched in 2001, and the Mars Survey Orbital Vehicle (MRO), which was launched in 2005, have long been in service longer than originally designed.

MAVEN was one of five NASA Mars vehicle trunking communications satellites, and the remaining four are still in orbit, namely the Odyssey, the Mars Survey Orbiter and the Mars Express and Microgas Orbiters of the European Space Agency.

MAVEN is the first detector for the systematic study of the evolution of the atmosphere of Mars and its interaction with the solar wind on board a dedicated instrument. Even after the detector has lost contact, the large amounts of data it collects in orbit will continue to contribute to many new scientific discoveries by powerful scientists.

In an official communiqué, Louise Proctor, Director of Planetary Science, NASA, mentioned: “Mavan accumulated detection data will continue to provide key references to Mars research for decades to come.”

Curly also said: “We are about to file a big observation data set, which also holds a great deal of scientific value to be dug up.”
