Two Chinese astronauts, or taikonauts, are currently aboard an experimental space station.

Tiangong 2, also known as the Heavenly Palace, is the second laboratory to be launched by the world's second-largest economy, and on its decks the dedicated duo will conduct experiments aimed at creating a permanent space station by 2022.

As China’s extraterrestrial ambitions lift off, here’s a numerical look at the country’s past, present and future in space.

6 – This is China’s sixth manned mission into space.

30 – The number of days the taikonauts are planning to spend aboard Tiangong 2, making it China’s longest manned mission to space.

$6.1 billion – According to the OECD, this was China’s space budget in 2013. It's still some way behind US spending, as this chart shows.

These countries have the biggest space budgets

20 – The number of passengers a state-backed space plane hopes to carry to the edge of space – at an estimated cost of $200,000 to $250,000 for a ticket.

2020 – The year by which China is planning to launch a rover to Mars. In December 2013, the country landed Chang’e 3 and its rover, Yutu, on the moon. It was the third country to perform a soft landing on the moon's surface.

China aims to launch its next unmanned lunar probe in 2017, with the key aim of collecting and bringing back lunar samples, an official said on Monday, after the country's first probe landed successfully on the moon over the weekend. Photographers were permitted to take photos of the video screen inside the control center.  Picture taken December 15, 2013. REUTERS/Stringer (CHINA - Tags: SCIENCE TECHNOLOGY POLITICS) CHINA OUT.
