Same for the successful Indian mars mission, just shows asian math is good

NASA and Roscosmos were leaders in space exploration partly because they had a head-start with those nazi rocket scientists captured after WW2.

True. Anyway there was a concerted effort and the space race was real. Hence great risks were taken. 

Watch first man on Netflix. Shows what the astronauts went through and the death rate.

Quite a feat by the Chinese...

China has successfully landed a spacecraft on Mars, state media announced early on Saturday.

The six-wheeled Zhurong robot was targeting Utopia Planitia, a vast terrain in the planet's northern hemisphere.

The vehicle used a combination of a protective capsule, a parachute and a rocket platform to make the descent.

The successful touchdown is a remarkable achievement, given the difficult nature of the task.

Only the Americans have really mastered landing on Mars until now. With this landing, China becomes the second country to put a rover on Mars.

Chinese President Xi Jinping congratulated the team's "outstanding achievement" in a special message.

"You were brave enough for the challenge, pursued excellence and placed our country in the advanced ranks of planetary exploration," he said.

The probe officially landed at 07:18 on Saturday, Beijing time (Friday 23:18 GMT), according to state media.

It took 17 minutes to unfold its solar panels and send a signal back to Earth.

Zhurong, which means God of Fire, was carried to Mars on the Tianwen-1 orbiter, which arrived above the planet in February.

The time since has been spent surveying Utopia, taking high-resolution images to pinpoint the safest place to put down.

The aim with all such ventures is to pick a spot, as far as possible, that is devoid of imposing craters and large boulders.

Chinese engineers have to follow events with a time lag.

The current distance to Mars is 320 million km, which means radio messages take almost 18 minutes to reach Earth.

Every stage of the Zhurong's approach to the surface therefore has to be managed autonomously.

The entry (into the atmosphere), descent and landing strategy follows a familiar architecture.

At the chosen moment, the rover, encased in an aeroshell, is released from the Tianwen orbiter and dives downwards.

A heatshield on the capsule slows the fall by pushing up against the Martian air. A parachute then opens to reduce the velocity still further. Finally, the robot breaks away on a rocket-powered bench for the manoeuvres that take it to the ground.

It is a daunting challenge, but China has shown great competence of late in its space endeavours, which have included putting two rovers on the Moon.

Now that Zhurong has got down successfully, scientists will try to get at least 90 Martian days of service out of it, studying the local geology. A day, or Sol, on Mars lasts 24 hours and 39 minutes.

The robot looks a lot like the American space agency's (Nasa) Spirit and Opportunity vehicles from the 2000s. It weighs some 240kg and is powered by fold-out solar panels.

A tall mast carries cameras to take pictures and aid navigation; five additional instruments will help assess the mineralogy of local rocks and look for any water-ice below ground.

 

Chinese rocket debris crashes into Indian Ocean - state media https://www.bbc.co.uk/news/science-environment-57045058

But they forgot to mention another crash on 29 April 2021 😂

Okok don't fight don't angry don't upset. 

Let's pack all the PRCs and India Indians and send them all to Mars.. 

Btw,  I not AMDK and I not Malay,  so I not racist hor...

Chinese and indian are well known for their math and good grades. Thats why alot silicon valley comes from asian and also many CEOs in reputable MNCs have indian origin

the difference between the space x and the China ones are the space x are planned for deorbit burn which could control its reentry path (this case seems they have some issue or did not carry out with that procedure) but the china ones never plan for such burn and they dont care where its debris will burn up which might result in those unburned debris falling into inhabited area.

Where did u get this info for Space X rockets with controlled deorbit from? 😆

Don’t think they ever did this for their 2nd stage

space x plan for deorbit not because they care about the debris , its for other purpose.

china never plan for the debris falling back to earth, but that is the same for every country that shoot rocket into space since the start of space age.

china only account for a small% those unplanned fall of debris.

Why can't they add another set of rockets onto the debris and fire the debris into the deep space or the sun instead of letting them fall back to earth. 

The sun could have melt the debris before reaching the sun atmosphere

because there is no international standard on this , no international agreement, if every 1 is doing the same we cannot expect china or india or usa to spend more money to make it fly into deeper space.

and the main reason is because since the start of space age these uncontrolled fall of rocket back have not cause any damage before. there is a very minor case very very long ago, read about it some where else.

targeting and criticize china or any 1 for having uncontrolled entry of rocket back to earth is like how to say huh...

u watch 'MAD MAX'?? imagine those bad guy chasing MEL and shouting cursing and complaining  he is driving too fast, he is speeding , 🤣

Comparing USA who started the space exploration in the 50's and China in th 90's.

China have caught up with USA by 40+ years..... 

Considering China still in-fighting (Communist vs KMT) and the Japanese in the 40's.

It is in some part due to espionage and reverse-engineering russian technology

it was widely reported that part of the rocket didnt complete deorbiting... i have no way to verify if space x want to lie to the whole world about this...
