    Tianwen 1 enters Mars' polar orbit

    China's Tianwen 1 robotic probe entered orbit above Mars' polar regions on Monday, moving closer to the red planet, the China National Space Administration said.

    The spacecraft activated its 3,000-Newton-thrust orbital-control engine at 5 pm to conduct an orbital plane change maneuver to enter polar orbit with a perigee of about 265 kilometers above the red planet, the administration said in a brief statement.

    Next, the probe will carry out several orbital adjustment operations to move itself into a parking orbit.

    In parking orbit, it will make observations and investigations of the preset landing site.

    Before the latest maneuver, Tianwen 1 was travelling around an elliptical Martian orbit with a perigee of about 400 kilometers after its arrival in Mars' gravitational field on Wednesday night, becoming the first Chinese spacecraft to reach the planet.

    Tianwen 1, the country's first independent Mars mission, was launched by a Long March 5 heavy-lift carrier rocket on July 23 from the Wenchang Space Launch Center in Hainan province, kicking off the nation's planetary exploration program.

    The 5-metric ton probe, which consists of two major parts - the orbiter and the landing capsule - flew for 202 days and about 475 million km on its journey to Mars. Its average flight speed was about 100,000 kilometers per hour.

    During its journey, the spacecraft conducted four midcourse corrections and a deep-space orbital maneuver to make sure it was always precisely aimed at Mars.

    The Tianwen 1 mission's ultimate goal is to land a rover in May or June on the southern part of Mars' Utopia Planitia - a large plain within Utopia, the largest recognized impact basin in the solar system? -to conduct scientific surveys.

    Tianwen 1 is the world's 46th Mars exploration mission since October 1960, when the former Soviet Union launched the first Mars-bound spacecraft. Only 18 of those missions were successful.
