China Unveils First Mars Photos From Zhurong Rover (space.com) 87

Posted by BeauHD from the out-of-this-world-photography dept.
China has released the first photographs taken by its Zhurong rover, which touched down on Mars late on May 14 as part of the country's Tianwen-1 mission. Space.com reports: The China National Space Administration (CNSA), which runs the mission, has released two Mars photographs taken by the rover: one in color and one in black and white. Both images show parts of the rover and its lander against a backdrop of Utopia Planitia, the expansive northern plain that Zhurong will explore during its mission.

The color image shows a view looking to the rear of Zhurong from a navigation camera above the rover's main deck. Solar arrays are visible, as are some surface rocks and features. The black and white image is from an obstacle avoidance camera at the front of the rover. It was captured with a wide-angle lens that also revealed a view of the Mars horizon in the distance, as well as two subsurface radar instruments on the rover itself. In addition to the photos from the surface, CNSA also released two short videos of the orbiter and Zhurong rover's landing capsule separating during Friday's maneuver. Both videos come from cameras on the orbiter and show the capsule pulling away.

      The difference between the US efforts in this field and the Chinese is infrastructure.
      Sending information across a distance of 50 million km is hard. Most Mars landers carry a transmitter that can communicate directly with Earth, but at a very low bitrate. You won't be sending high-res images via that link, just telemetry.
      Most communication is done via a relay satellite in Mars orbit. The US has two of those. These are in sun-synchronous (almost polar) orbits, which means they'll be in view of the rover once a day for maybe 10 minutes. The link from the lander to the satellite is much faster than the lander-Earth link, but you have to wait until the sat is overhead.

      Tianwen-1 has an orbiter, but the one time you can pretty much guarantee that an orbiter that arrives together with its lander will be out of sight of the lander is during the landing. IIRC they used an ESA orbiter for the first relay session.

      Then you have to send the data from the relay sat to a ground station, which can only be done when the ground station is in view. NASA has 3 ground stations with at least 4 large antennas each, spread around the world so at least one is in view at all times. China has one tracking station abroad (Argentina) which I suspect leaves gaps in their coverage.

      Then there's the difference in mentality. NASA sees the value of PR and will make accommodations to get good PR out of these events. The CSA is more low-key because it doesn't live and die by public opinion.
