Does Mars soil have nutrients?
Fertilizing Mars Research suggests Martian soil has some of the nutrients plants need to grow and survive (see “Plants’ Nutrients,” right). These fertilizers also supply nutrients to the crops that some soils do not have.
Is Mars rich in minerals?
Minerals produced through hydrothermal alteration and weathering of primary basaltic minerals are also present on Mars. Secondary minerals include hematite, phyllosilicates (clay minerals), goethite, jarosite, iron sulfate minerals, opaline silica, and gypsum.
Can u fart in space?
On Earth, farts are typically no big deal — smelly, harmless, and they quickly dissipate. But if you’re an astronaut, every fart is a ticking time bomb. The gases in farts are flammable, which can quickly become a problem in a tiny pressurized capsule in the middle of space where your fart gases have no where to go.

What happens if u cry in space?

Can astronauts walk after being in space?
Astronauts and cosmonauts that live in space for six months to a year experience physical changes that have noticeable effects once they return to Earth’s gravity, including changes to vision, balance, coordination, blood pressure, and the ability to walk, which impact their ability to perform basic tasks.
Do you poop when you are in a coma?
When you are in a coma, you will be confined to bed, and all physical needs (such as bathing, turning, and bowel and bladder care) will be taken care of by someone else. General weakness is also very common as you approach death.
