Remember how China’s Tianwen-1 spacecraft released a remote camera to take a picture of itself during its flight to Mars, back in late 2020? Now in Mars orbit, Tianwen-1 has done it again, releasing another mini remote camera. Except this time, the planet Mars is part of the view.
The images are stunning.
The China National Space Administration (CNSA) published three pictures, including a shot of the spacecraft in orbit with Mars in the background, a picture of Mars’ northern ice caps, and the first full photo of the orbiter.

While this isn’t the first time one spacecraft has taken a picture of another spacecraft at Mars, this concept of bringing your own selfie camera is pretty darn innovative.
NASA’s Mars Odyssey spacecraft was imaged twice by the camera aboard NASA’s Mars Global Surveyor in 2005. It Global Surveyor also took a picture of the European Space Agency’s Mars Express, and these were the first pictures of any spacecraft orbiting Mars ever taken by another spacecraft orbiting Mars.

In addition to Tianwen-1 having its own remote cameras, the companion Chinese Mars lander and Zhurong rover placed a wireless remote camera on the ground to take pictures of both the rover and lander.

While our first reaction is that every spacecraft should deploy a buddy with a camera to allow us to see how the spacecraft is doing, this also might be a risky idea. For example, what if we could see actual pictures of the James Webb Space Telescope deploying its giant sunshield instead of engineers just seeing telemetry data? But also imagine a free-flying little camera hovering around JWST – and then inadvertently crashing into it. Might be too chancy.

Tianwen 1 launched in July 2020 from the Wenchang Space Launch Center in Hainan province. It entered Mars’ orbit in February, 2021. A few months later, a landing capsule was released, sending a lander and orbiter to the surface of the planet, landing on May 15. This made China the third country, after the United States and Russia, (when it was the USSR, in 1971 and 1973), to successfully conduct a Mars landing.
CNSA reported that as of January 1, 2022
