image captionTianwen-1 took a selfie after launch using a free-flying camera
China says it has successfully put its Tianwen-1 mission in orbit around Mars.
It's the first time the country has managed to get a spacecraft to the Red Planet and comes a day after the United Arab Emirates accomplished the same feat.
Tianwen-1, or "Questions to Heaven", comprises an orbiter and a rover.
Engineers will bide their time before despatching the wheeled robot to the surface but the expectation is that this will happen in May or June.
Wednesday's orbit insertion underlines again the rapid progress China's space programme is making.
It follows December's impressive mission to retrieve rock and soil samples from Earth's Moon - by any measure a very complex undertaking.

image captionNasa's 1976 Viking-2 mission also landed on Utopia Planitia
Tianwen-1's mission, particularly the surface element, will be no less challenging.
Its five-tonne spacecraft stack, made up of orbiter and rover, was launched from Wenchang spaceport in July, and travelled nearly half a billion km to rendezvous with the Red Planet.
Engineers had planned a 14-minute braking burn on the orbiter's 3,000-newton thruster, with the expectation that this would reduce its 23km/s velocity sufficiently to allow capture by Mars' gravity.
The manoeuvre was automated; it had to be. Radio commands currently take 11 minutes to traverse the 190 million km now separating Earth from Mars.
It should have put Tianwen-1 in an initial large ellipse that comes in as close as 400km from the surface and out as far as 180,000km.
This will be trimmed over time to become tighter and more circularised.

In contrast to the Emiratis' live TV coverage on Tuesday, China chose to report the orbit insertion at Mars only after it had occurred.
It was clear early on, however, that events were proceeding as they should because amateur radio enthusiasts could listen across Tianwen-1's signals, and they could see each milestone in the manoeuvre was being achieved.
media captionHow long does it take to get to Mars and why is it so difficult?
China is following the strategy employed by the Americans for their successful Viking landers in the mid-1970s. The idea then was to make orbit first and only later send a robot to the surface.
A period of reconnaissance will now follow but Tianwen-1's primary choice for a touchdown is a flat plain within the Utopia impact basin just north of Mars' equator.
The rover, which has yet to be named, looks a lot like the US space agency's (Nasa) Spirit and Opportunity rovers 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.
A key experiment will be the ground-penetrating radar, which should be able to sense geological layers at depths of many metres.

image captionTianwen-1 took this image of Mars from a distance of 2 million km
This surface investigation is really only half the mission, however, because the orbiter that has been shepherding the rover will also study the planet, using a suite of seven remote-sensing instruments.
Like previous satellites, this spacecraft will observe characteristics of the high atmosphere and examine the structures and composition of the surface. High- and medium-resolution cameras should return some impressive pictures.
Tinawen-1 is one of three missions arriving at Mars this February.
The UAE's Hope probe made it safely into orbit on Tuesday. Next week, Nasa will attempt to put another of its big rovers on the surface.

Mars landing: Photo shows Perseverance about to touch down

image captionPerseverance viewed from its rocket cradle just before landing
The American space agency has released an astonishing image sent back from Mars by its Perseverance rover.
It shows the robot heading down to the ground on Thursday to make its landing. It was acquired by the rocket cradle that placed the vehicle on the surface.
Perseverance has a large amount of data in its memory banks which it is gradually offloading to Earth.
Among other pictures is a view from a satellite that captures the rover in the parachute phase of its descent.
This also represents an immense technical achievement because the satellite - the Mars Reconnaissance Orbiter - was approximately 700km from Perseverance at the time and traveling at about 3km/s.
Nasa is promising more in the next few days.
This offering will include short movies shot during the Entry, Descent and Landing (EDL) sequence - with sound.
Perseverance has been put in a near-equatorial Martian crater known as Jezero where it will search for signs of past microbial life.
image copyrightNASA/JPL-Caltech/University of Arizona
image captionThe overflying Mars Reconnaissance Orbiter was able to see the descending rover's parachute
Adam Steltzner, the Perseverance rover's chief engineer, said the downward-looking view on to the robot would become an iconic image in the history of space exploration.
"This is an image of the rover Perseverance slung beneath the descent stage, its propulsion backpack, as it is being lowered to the surface of Mars," he explained.
"You can see the dust kicked up by the engines. We're probably about 2m or so above the surface of Mars.
"You can see the mechanical bridles that hold the rover underneath the descent stage - three straight lines heading down to the top deck. And then the curly electrical umbilical that is taking all of the electrical signals from the descent stage down to the computer inside the belly of the rover, [including] the ones and zeros that represent this image."

image captionA forward view from the rover on Mars. The shadow comes from the robot arm
Engineers report Perseverance to be in good health, as they gradually commission its systems.
All the hardware needs to be assessed to be sure nothing was damaged during Thursday's plunge through the Martian atmosphere to the ground.

image captionOne tonne of high technology: Seven instruments, multiple cameras, microphones and a big drill
The most detailed pictures of Jezero Crater will come next week after Perseverance has raised its navigation mast which carries the main science cameras.
"Once the mast is successfully deployed, which will be on Saturday, we will proceed by taking lots of images. We'll do a deck panorama of the rover. And we're also going to do a full panorama of our landscape around us," said Pauline Hwang, Perseverance's surface strategic mission manager.
image copyrightNASA/JPL-CALTECH
image captionScientists are already starting to analyse the rocks on the ground
Perseverance's landing technologies put it down almost bang on the targeted touchdown zone, about 2km to the southeast of what remains of an ancient river delta that formed at the edge of a lake.
It is sitting on a flat piece of ground at the boundary of two geologic units - a smooth unit under the wheels of the rover that contains dark volcanic rocks; and a rougher unit that has rocks with a lot of the mineral olivine in them.
The science team was itching to start exploring the crater, said deputy project scientist Katie Stack Morgan.
Even now, with just this limited first release of pictures, there were fascinating rocks to discuss, she told reporters.
"We're picking out different colours and tones and textures, to try to figure out what these rocks might represent and what depositional process might have put these rocks on the surface of Mars."
Perseverance's landing spot is in a quadrangle that the science team has informally called Canyon de Chelly after the National Monument in the US State of Arizona. Any rocks the robot investigates in this 1.2km by 1.2km area will also now be given names that relate to the American park, which is famous for its sandstone spire known as Spider Rock.
The $2.7bn (£1.9bn) robot is the fifth rover to be put on Mars by Nasa.
Its initial mission will last one Martian year (roughly two Earth years), although it's hard to see the agency not extending this if all the hardware remains healthy.
As well as searching for signs of life, Perseverance's other key objective is to select and package rock samples that can be brought back to Earth laboratories by later missions.
