Following are the major facts and figures about Shenzhou-6, China's second manned spacecraft which was put into orbit Wednesday and currently on its space flight mission:

680,000 kilometer

-- Shenzhou-6 had made a space journey of 680,000 kilometer in its first 24-hour flight as of 9:00 a.m. Thursday, making the astronauts Fei Junlong and Nie Haisheng the Chinese record-breakers in making the longest journey in one day;

90 minutes

-- It took about 90 minutes for Shenzhou-6 to make a single circle around the Earth, and the astronauts would experience sunrise and sunset for 16 times in one day and night;

343 kilometer

-- Shenzhou-6 flew in a circular orbit 343 kilometers above the Earth after the orbit shift from an elliptical orbit in its fifth circle around the Earth;

7.820185 kilometers/ps

-- Shenzhou-6 is now traveling at a speed of 7.820185 kilometers per second on a circular orbit;

50 kilograms

-- Shenzhou-6 is carried with 50-kilogram oxygen, not only enough to satisfy the needs of two astronauts during their multi-day flight, but also to meet an emergency demand if necessary;

17-25 degrees centigrade

-- Experts say the environment in the re-entry capsule of Shenzhou-6 is comfortable, with the temperature from 17 to 25 degrees centigrade, and relative humidity from 30 percent to 70 percent;

Two billion yuan (250 million US dollars)

-- Each launch of a spacecraft costs two billion yuan; The orbital capsule of China's Shenzhou spacecraft can be left in the space for further research, which could save the launching cost and increase the efficiency of China's aerospace technology;

110 technical modifications

-- Compared with Shenzhou-5, more than 110 technical modifications have been made for the Shenzhou-6, which is 9.2 meters in total length and more than eight tons in weight;

11 kilograms

-- The 11-kilogram astronautic-suits for Shenzhou-6's astronauts, worth hundreds of thousands of yuan each, can keep astronauts safe and sound in six hours if accidental pressure loss occurs in the capsule;

100 percent

-- The carrier rocket Long March II F has successfully sent Shenzhou spacecraft into space for six times, with success rate reaching 100 percent;

451 astronauts

-- With the successful launch of Shenzhou-6, there are totally 451 astronauts visiting space in the world;

48.7 years old

-- The average age of Shenzhou-6's chief commanders and designers is only 48.7 years old while that for Shenzhou-5 53.6;

1,700 meters

-- Astronauts in the space can drink 99.99999-percent-pure water that comes from 1,700-meters-deep underground;

50-odd varieties

-- 50-odd varieties of foodstuff, totaling more than 40 kg, are prepared for the astronauts;

2.8 meters

-- Its re-entry module, with a diameter of 2.8 meters, is designed for three astronauts, and thus has enough room for the astronaut movement needs.
