China prepares to launch for Mars...

Long March 5 rolled out for July 23 launch of China’s Tianwen-1 Mars mission


China is preparing to launch its Tianwen-1 Mars orbiter and rover next week with the rollout of the mission’s Long March 5 launch vehicle.

The roughly 878-metric-ton heavy-lift Long March 5 was vertically transferred to its launch area at the coastal Wenchang Satellite Launch Center late Thursday Eastern.

The rollout indicates that China will launch Tianwen-1, the country’s first independent interplanetary mission, next week.

* * *

If successful the spacecraft will arrive at Mars in February 2021. The rover, inside an entry vehicle atop the orbiter, will remain attached to the orbiter in Mars orbit for 2-3 months before the landing attempt,

* * *

The Tianwen-1 orbiter carries seven science payloads. It is equipped with a high-resolution camera comparable to HiRise on board NASA’s Mars Reconnaissance Orbiter. It also carries a medium-resolution camera, subsurface radar, mineralogy spectrometer, neutral and energetic particle analyzers and a magnetometer. The orbiter, designed to operate for one Mars year, or 687 Earth days, will also play a relay role for the mission rover.

The roughly 240-kilogram solar-powered rover is nearly twice the mass of China’s ‘Yutu’ lunar rovers. It will carry a ground-penetrating radar, multispectral camera and a Laser Induced Breakdown Spectroscopy instrument. Other payloads will analyze the climate and magnetic environment. The rover will attempt to land in a southern section of Utopia Planitia where it is designed to operate for 90 Mars days.

It's on its way!

China's Tianwen-1 Mars rover rockets away from Earth
China has launched its first rover mission to Mars.

The six-wheeled robot, encapsulated in a protective probe, was lifted off Earth by a Long March 5 rocket from the Wenchang spaceport on Hainan Island at 12:40 local time (04:40 GMT).

It should arrive in orbit around the Red Planet in February.

Called Tianwen-1, or "Questions to Heaven", the rover won't actually try to land on the surface for a further two to three months.

This wait-and-see strategy was used successfully by the American Viking landers in the 1970s. It will allow engineers to assess the atmospheric conditions on Mars before attempting what will be a hazardous descent.

Tianwen-1 is one of three missions setting off to Mars in the space of 11 days.

On Monday, the United Arab Emirates (UAE) launched its Hope satellite towards the Red Planet. And in a week from now, the US space agency (Nasa) aims to despatch its next-generation rover, Perseverance.

An interesting article on the Soviet Mars mission - I hadn't realized they made the first soft landing on Mars... and the first image transmitted from the surface (if you can call a screenful of static an "image"). Also interesting the attempts by NASA and others to find the probe in later Mars observation missions....

Bob & Doug are back from their first-ever crewed SpaceX Mission to the ISS, 2 months after their launch atop a Falcon 9 rocket from Cape Canaveral:
