Shenzhou VI spacecraft is 9.2 meters long and has a total mass of 7790 kilograms. The take-off mass of the Long March II F carrier rocket is 479.3 tons, and its milky white spacecraft tower assembly is 58.3 meters high. Please calculate: the mass of the spacecraft accounts for (1.6)% of the takeoff mass.

Solution: 7790 kg =7.79 tons

7.79/(479.3+7.79)* 100%

=7.79/487.09* 100%

≈ 1.6%

A: The mass of the spacecraft accounts for 1.6% of the takeoff mass.
