They've dubbed it the "mission to the edge of space".
The pedants will no doubt point out that Felix Baumgartner's attempt to make the highest ever skydive from 120,000ft (36.5km) is nowhere near space; and of course, they'd be right - the so-called Karman line is judged to be at about 100km (328,000ft). But this kind of misses the point.
Build it and they will come. The project to make a car capable of going 1,000mph (1,610km/h) is finalising the budget to complete its construction.
There then requires just the money to run it for at least two years - the time it will take first to breach the current land speed record (763mph or 1,228km/h), and thereafter to raise it beyond 1,000mph.
Nasa's Juno spacecraft will execute the second of two big burns on its main engine on Tuesday.
The manoeuvre will put the probe on a path to flyby Earth in October next year. This sweep around the home planet will then give the mission a gravitational boost and the velocity required to get it out to Jupiter in July 2016.
"I hope to do something as great in my life in the future, but if I don't - this will have been enough."
Adam Steltzner has had a little time to reflect on the historic touchdown of the Curiosity rover on Mars, although he confesses the adrenaline of the past few days means he hasn't himself yet landed back on Earth.
John Grotzinger is the project scientist on Nasa's latest multi-billion-dollar mission to Mars.
He's going to become a familiar face in the coming months as he explains to TV audiences the importance of the discoveries that are made by the most sophisticated spacecraft ever sent to touch the surface of another world.
The smiles said it all. Jing Haipeng, commander of the Shenzhou-9 crew, was the first to emerge from the return capsule, followed by his flight engineers Liu Wang and the country's first woman astronaut, Liu Yang.
The Shenzhou-9 mission posted a series of firsts: the first manned automatic and manual dockings; the first long-duration spaceflight; and the first crew to live aboard a permanently orbiting module, Tiangong-1.
The smiles said it all. Jing Haipeng, commander of the Shenzhou-9 crew, was the first to emerge from the return capsule, followed by his flight engineers, Liu Wang and the country's first woman astronaut, Liu Yang. Job well done. But their grin is shared across the whole Chinese nation today.
The cost of human spaceflight is so high that you really only go in for this type of ostentatious expenditure if you think you can carry it off, and the Chinese have done that with aplomb these past few days.
