Name any two areas of high latitudes in the world, where gathering economic activity is practised. (A.I. 2010)
Answers
Explanation:
When astronauts leave for a mission, they have to carry non- perishable food as
possible in space. The space food they carry must also be easy to eat without making a mess since the
astronauts are outside the gravitational field, and any crumbs from the food could float around and get
stuck in the equipment or in the astronauts' eyes. Because astronauts are in space for weeks or months at
a time, they are usually unable to carry fresh food such as fruit and vegetables.
(Para 1)
Many types of space food are either partially or fully dehydrated or sealed. Though there is no
refrigerator on board a space shuttle, an oven is there, so astronauts can heat up or bake their space food
as necessary. While in space, astronauts generally use flour tortillas for sandwiches rather than bread.
Ketchup, mustard and mayonnaise are provided in their standard form but salt and pepper are provided
only in liquid form, because the powdered version is likely to float away. Today, a variety of menu items
are available for astronauts as space food. (Para 2)
Space food is provided in disposable containers that can be attached to the astronauts' meal tray, which is
strapped to his lap, so that the container does not consume each part of the meal separately, not starting
on another course until the previous one is finished. Once the food has been eaten, the meal packaging
must be disposed of into a trash compactor to eliminate waste. The utensils and trays are cleaned with
wet wipes.
