Earth and the Moon appear as small crescents in the empty darkness of space in surreal photo captured by China's Mars probe en route to the Red Planet

China's Mars probe, Tianwen-1, has beamed back a photo of the Earth and the Moon as it heads towards the Red Planet.
The image, which shows the two celestial bodies as small crescents in the empty darkness of space, was taken 746,000 miles (1.2 million kilometres) away from Earth.
The black and white photo simultaneously reveals the shape of the directly sunlit portion of the Earth, which appears to the left, and the smaller Moon, on the right. 
It was captured just three days after the mission launched last Thursday (July 23), and precedes NASA's launch of its Perseverance rover, scheduled for around 12.50pm BST tomorrow.
China, the US and the UAE, which launched a probe on July 20, are all taking advantage of a period when Mars and Earth are favourably aligned to launch exploratory missions to the Red Planet.

The image was captured using the optical navigation sensor on board the unmanned space probe, which is under the operation of the flight control team from the Beijing Aerospace Command and Control Center, in close collaboration with China Academy of Space Technology.  
The China National Space Administration (CNSA) said on Tuesday that Tianwen-1, which has left Earth's gravitational field, 'is currently in good flight conditions, has balanced fuel and is operating normally.'  
Ground measurement, control and tracking are stable, and flight control and data reception carried out in order, it added. 
The rover had by Tuesday travelled least 746,000 miles from Earth, the agency said – just 2 per cent of the 34 million miles it must traverse before it reaches Mars. 
China successfully launched Tianwen-1 on July 23 aboard a Long March 5 Y-4 carrier rocket at 12:41pm (04:41 GMT) from Wenchang Space Launch Centre on the southern island province of Hainan, China.

The craft, which consists of an orbiter, lander and rover, measures just over six feet in height (1.85m) and weighs 530 pounds (240kg). 
The probe is due to arrive on the Red Planet next February after a seven-month, 34-million-mile voyage. 
Once it gets to Mars, it will survey the composition, types of substance, geological structure and meteorological environment of the Martian surface, and look for signs of alien life.  
The Tianwen-1 mission, given a name that means 'Questions to Heaven,' aims to enter Martian orbit seven months after the launch and release a small rover to study the planet's surface.

Tianwen-1 represents the latest milestone in Beijing's space programme, which has sent two rovers to the Moon and set up a satellite navigation, Beidou, to rival the United States' GPS.
This is not China's first attempt at Mars – in 2011, a Chinese orbiter accompanying a Russian mission was lost when the spacecraft failed to get out of Earth's orbit after launching from Kazakhstan, eventually burning up in the atmosphere.  
The launch of Tianwen-1, the country's first Mars lander, followed the UAE's launch of its Hope probe on July 20.
Hope, which is also due to reach Mars in February 2021, will not land on the Martian surface but take readings from the Red Planet's atmosphere. 
But the race to watch is between the US and China, which has worked furiously to try and match Washington's supremacy in space.
NASA, the American space agency, has already sent four rovers to Mars since the late 1990s.
The next one, Perseverance, is an SUV-sized vehicle that will look for signs of ancient microbial life, and gather rock and soil samples with the goal of bringing them back to Earth on another mission in 2031.
Perseverance will carry instruments geared to search for the carbon building blocks of life and other microbes and to reconstruct the geological history of the Red Planet

Perseverance blasts off from Florida at 7:50am EDT (12.50pm BST) tomorrow (Thursday, July 30) and is due to touch down on the Martian surface in February too. 
NASA on Monday gave its latest Mars rover Perseverance the all clear to launch later this week on a mission to seek out signs of ancient microbial life.
'The launch readiness review is complete, and we are indeed go for launch,' administrator Jim Bridenstine said, as quoted by AFP. 
'We are in extraordinary times right now with the coronavirus pandemic, and yet we have in fact persevered and we have protected this mission because it is so important.' 
Perseverance is carrying seven instruments that will analyse samples from the surface, including an advanced panoramic camera, a ground-penetrating radar and an X-ray fluorescence spectrometer for analysis of chemical elements.   
Perseverance will also be trialling technologies to help astronauts make future expeditions to, and eventually live and work on, Mars. 
These include testing a method for producing oxygen from the Martian atmosphere, identifying resources such as water beneath the surface, improving landing techniques and characterising weather and other environmental conditions.  

THREE MISSIONS TO MARS IN THE SPACE OF 10 DAYS

There are three major missions bound for Mars in the space of just 10 days this month - the UAE's Hope orbiter, China's Tianwen-1 craft and NASA's Perseverance rover. 
The countries are taking advantage of a period when Earth and Mars are favourably aligned for a relatively short journey.  
July 20: Hope (UAE)
The 3,000lb (1,350kg) craft (pictured) will complete one orbit every 55 hours for a total of one Martian year — 687 Earth days
The 3,000lb (1,350kg) craft (pictured) will complete one orbit every 55 hours for a total of one Martian year — 687 Earth days
 - The 2,970-pound probe was built entirely within the Emirates, launched from Japan and will take seven months to reach the Red Planet. 
- When the orbiter gets there in February 2021, it will stay in orbit for a whole Martian year – 687 days. 
- Hope will not land on the Martian surface but take readings from the Red Planet's atmosphere.  
- Hope will help answer key questions about the Martian atmosphere and the loss of hydrogen and oxygen gases into space over the span of one Martian year – called a 'sol'. 
- Three instruments mounted on the probe will provide a picture of Mars's atmosphere throughout the year, and all of the data gathered will be made widely available. 
- This includes an infrared spectrometer to measure the lower atmosphere and temperature, a high-resolution imager to study the ozone and another to look at levels of hydrogen and oxygen up to 27,000 miles from the surface. 
July 23: Tianwen-1

 - This robotic spacecraft consists of an orbiter (stationed in the atmosphere), a lander (stationary on the planet's surface) and a rover (roaming the surface). 
- The craft measures just over six feet in height (1.85m) and weighs 530 pounds (240kg). 
- It will survey the composition, types of substance, geological structure and meteorological environment of the Martian surface. 
- The solar-powered machine is designed to work on Mars for three Martian months, about 92 Earth days.
- It includes a geological camera, a multispectral camera, a subsurface detection radar, a surface composition detector, a surface magnetic field detector and a weather detector.
- A poem pondering on the stars and planets written over 2000 years ago was the inspiration for the name of China's first exploration mission to Mars. 
- Called Tianwen (天问), the poem was written by ancient Chinese literati and politician Qu Yuan (339-278BC), who lived in the Chu State (770-223BC). 
July 30: Perseverance
NASA's Mars 2020 Rover will pick up samples of rock and soil from the red planet, deposit them in tubes and leave them on the ground for a future mission to return them to Earth.

- NASA's Perseverance rover is the heaviest payload yet to go to the Red Planet - at a car-sized 2,259 pounds (1,025kg).  
The mission will seek signs of past microbial life on Mars and collect rock and soil samples for eventual return to Earth.   
- The Mars Perseverance rover introduces a drill that can collect core samples of the most promising rocks and soils and set them aside in a 'cache' on the surface of Mars. 
- The rover will travel using an ultraviolet laser to determine what minerals and compounds are present in the soil, based on the way the light scatters. 
- The Mars 2020 rover, which was built at NASA's Jet Propulsion Laboratory in Pasadena, California., is now at the Kennedy Space Center in Florida for final preparations. 
- It launches to space on July 30 and is set to touch down on Mars in 12 months. 
- It has a mission duration of 1 Mars year (668 sols or 687 Earth days) and will touch down on the planet's Jezero crater on Mars in February 2021.
