Food and Drink. Fighter pilots do not have any problem taking food and drinks on flights. The biggest concern is to prevent foreign object damage (FOD) from items like crumbs, bottles, bags, etc. Otherwise, there are plenty of places to carry food to eat: your helmet bag, G-Suit pockets and flight suit pockets.
Mercury has less mass than earth,the surface gravity on mercury is less than the surface gravity on Earth.The surface gravity on Mercury is about 38% of the surface gravity on Earth,so that means if you weighed 100kg then you would only be 38kg on Mercury.
Even our own bodies have gravity. The Earth's gravity is far stronger than our own so we don't notice the gravity our bodies possess. Gravity is affected by the size and proximity of objects. The Earth and the moon have a stronger pull on each other than the Earth and, say . . . , Jupiter because the Earth and moon are closer to one another.
