Of course, a mechanical or electronic failure is likely to end the mission long before the RTG wears out (same as on Curiosity)
Phil -------------------- ... because the Solar System ain't gonna map itself.

QUOTE Phil Stooke: I think it enters obliquely to provide a bit of lift for the skip entry. Like the Soyuz / Shenzhou capsule upon which is is based, this capsule appears to have a little aerofoil blade or wing sticking up at left side of Marcin600's second photo. By rolling the capsule during re-entry, this little wing can be used to steer the caspule left or right, and also up out of the atmosphere during the first re-entry pass, to make the "skip" maneuver. Having studied a few flown Soyuz capsules, that's my take on it anyway. |

...By rolling the capsule during re-entry, this little wing can be used to steer the caspule left or right, and also up out of the atmosphere during the first re-entry pass, to make the "skip" maneuver... from the official CNSA website - http://www.cnsa.gov.cn/english/n6465652/n6...98/content.html : „...The re-entry and landing started around 1 am when mission controllers uploaded high-accuracy navigation data to the orbiter-reentry capsule combination that was traveling around the Earth. The capsule then separated from the orbiter about 5,000 kilometers above the southern Atlantic Ocean and began to descend toward Earth. It entered the atmosphere at the second cosmic velocity, or 11.2 kilometers per second at 1:33 am, and soon bounced off the atmosphere to further slow down its ultrafast speed that could cause damage to the vehicle. Later, the craft reentered the atmosphere at a much slower speed of about 7.9 km per second, also known as the first cosmic velocity. When the module was about 10 km above the ground, it released its parachutes and smoothly landed on the snow-covered grasslands...” „...Chang'e 5's reentry capsule touched down on its preset landing site in Siziwang banner of the Inner Mongolia autonomous region at 1:59 am...” „...Next, the sealed samples will be transferred to specially designed laboratories for analyses, experiments and tests (...) A certain proportion of the samples will also be on public display to enhance science awareness among the public, especially young generations, sources close to the mission have said...” PS. On this website there are some official Chang'e 5 mission videos (No. 2 is quite large - over 0.3 GB) - http://www.cnsa.gov.cn/n6758823/n6758843/index.html and here are some official photos - http://www.cnsa.gov.cn/n6758823/n6758842/index.html |
