Any possibility of these recent failures a result of foreign sabotage?

Nah, if you consider the breadth of China's space launch program, this would be nothing more than a footnote for CNSA this year. A sabotage would only be attempted again something notable, i.e. Chang'e 5 or Tianwen. KZ-11, while notable, would hardly be considered the pinnacle of chinese space engineering today.

I doubt there would be an intentional launch failure caused by sabotage.

Far more likely would be a compromise of the sat itself with electronics or software. If the node is compromised, even quantum encryption is useless. To know what your enemy knows as he knows it is worth far more than merely destroying a satellite. That comes in handy only really when the shooting is about to start.

Here we go. China makes its first solo attempt to Mars.

Slippery conspiracy. Not worth discussing because the relevant people will of course look into everything in careful reviews of failure, more for learning than looking for saboteurs. No one here will know and it'll just welcome lot's of rubbish speculation and theories.

The chance for failure of a new platform has always been high in the USSR, Russia, USA too. But these new launch platforms in recent months have all been failing at least partially in later stages. This is disappointing. I'm sure this month's Mars mission will also be a failure. Mars missions around the world have around a 50% failure rate and China is attempting the most difficult combination - orbiter, lander, and rover in one single project and all on its first attempt. The Chinese Mars orbiter that blew up on the Russian rocket doesn't quite count since it was not exactly in control on the situation but I give this current mission lower than 50% chance of success. Still you gotta start somewhere and have everything there to fail and learn from why they failed. Maybe a second attempt will have better chances and progressively better.

I guess it depends on how you define success. If the lander fails within the last kilometer to Mars it could still be defined as 99.999% success.

CNSA is definitely NOT launching this one so that it fails. Thousands of people have given years of their hard work to reach this point.
Yes, the goal is lofty indeed, and Mars tends to swallow rather than embrace humanitys' fleeting attempts at reaching it.
But again, the only possible way to fail is to stop trying.

Does anyone have the planned launch date and time? I've found two launch dates: July 23 @ Noon or 16:56 (all UTC +8). I'm still looking for the UAE's launch date and time but no go. AFAIK, the US's Mars 2020 have not changed.

No they're certainly not building and launching with the aim of failing but the first attempt at such an ambitious project is riddled with uncertainties that are still unfamiliar until failures occur and can be investigated so that a learning process can commence. Preparing for failure is important for these people who have given so much because it allows them to better investigate how things failed and how they can be changed. It's an issue of technicalities. All the mission components are go but instruments to record and feed data are probably more embedded on this first attempt with this particular set up, stepping into the unknown of packing all this into the LM-5 with the aim of landing on Mars!

Anyway if the first step of launching is successful with this totally new payload for the LM-5, we'll find out how the landing goes in close to a year's time.
