At the beginning of December 2025 of the NASA MAVEN spacecraft, who spent more than a decade studying the upper atmosphere of Mars, suddenly stopped responding to Earth's calls. Telemetry signals, which were supposed to come through the powerful antennas of the Deep Space Network, were never received.
Since the loss of communication with the spacecraft, NASA engineers have been trying to figure out what happened to it. Analysis of the latest data indicated a possible unexpected change in the orientation of the device, because of which he "hid" behind the planet. Even the Curiosity rover's camera tried to find MAVEN in Martian orbit, but in vain. In mid-December, the agency made a forecast, according to which the chances of reestablishing the connection were assessed as very low. At the same time, the mission team does not lose optimism, because 16 the solar conjunction period should end in January of this year (period of time, when Mars and Earth are on opposite sides of the Sun, which interferes with communication) — and then there will be a new opportunity to try to communicate with the spacecraft. Despite the potential loss, the Martian science program will not stop. Other devices are operating in orbit, able to relay data from the surface.
