What do astronauts eat in space? What food requirements must be met on Earth in order to be allowed to space flights? These and other questions were answered.

After the holidays, interest in diets usually increases. Losing weight is on many people’s “new year’s resolutions” list. We usually want to lose weight as easily as we gained it. On the Internet, it is easy to stumble upon publications about the space diet or the diet of astronauts, promising a miraculous result – minus 20 kg in 20 days. Most of these published “space diets” on tabloid websites are complete nonsense, in fact.

What exactly is the astronauts’ diet? Should they eat the same menu repeatedly, every single day? What food requirements must be met on Earth in order to be allowed to space flights? These and other questions were answered by the doctor of the Russian crew members of the International Space Station Alexander Vasin and the cosmonaut of Roscosmos Ivan Wagner.

Carbon fiber is lighter and stronger than stainless steel. It has been widely used especially in the last two decades, and now we have a lot of experience in building and using it for different purposes. For example, it is most commonly used in the bodywork of a Formula 1 car and also the air box, the wings, the engine cover, the steering wheel, and the suspension. Space shuttles also use carbon fiber composite materials offering excellent heat resistance in order to withstand the extremely high temperatures they receive while atmospheric re-entry.

Carbon fiber is an extremely strong material compared to its weight. So, why did SpaceX engineers change their minds and use stainless steel instead of carbon fiber while building the Starship?

Here’s a quick guide to NASA’s payload classification: what is a payload, how NASA classifies them, and what are payload project categorizations.

Here are the orbital altitudes of many significant satellites (both artificial and natural – the latter only being the Moon) of Earth.
