What does a spacecraft have to provide the needs of the astronauts?

Astronauts must have oxygen, food, water, and rest. These needs are usually simple to meet on Earth; to meet these needs in space is very complicated. Spacecrafts carry their own sources of oxygen and nitrogen. These gases are circulated throughout the spacecraft to provide similar air to the one we breathe on Earth.

What would be needed for a mission to Mars?

You’ll need to bring breathable air, running on super reliable systems, and enough spare parts to carry you through a multiyear mission, because there’s nothing that you can forget. Once you leave for Mars, there’s no turning around and no resupply vehicles to send afterward.

What material would you need to take with you from Earth to Mars?

Silicon dioxide is the most common material on Mars, according to measurements taken by the Viking space probes, and is also a basic ingredient of glass. It is likely that glass products, including fiberglass, and structures could be constructed on Mars in much the same way as they are on Earth.

What would you need in a space habitat to survive on Mars?

Your checklist for living on the red planet from the author of The Martian

1. You’re going to need a pressure vessel.
2. You’re going to need oxygen.
3. You’re going to need radiation shielding.
4. You’re going to need water.
5. You’re going to need food.
6. Oh, come on.
7. You’re going to need energy.

What does a space colony need to survive?

Building colonies in space would require access to water, food, space, people, construction materials, energy, transportation, communications, life support, simulated gravity, radiation protection and capital investment. It is likely the colonies would be located near the necessary physical resources.

How does the space shuttle work?

The space shuttle launched like a rocket. But it landed like a glider airplane. The solid rocket boosters and the main engines on the orbiter helped the shuttle blast off from Earth like a rocket. When the shuttle orbiter returned to Earth, it came down from the sky like an airplane.

How are propellants loaded into the Space Shuttle?

Initial Shuttle propellantloading involves pumping hypergolic propellants into the orbiter’s aftand forward Orbital Maneuvering Systemand Reaction Control Systemstorage tanks, the orbiter’s hydraulic Auxiliary Power Units, and SRBhydraulic power units. These are hazardous operations, and while they are underway work on the launch pad is suspended.

What are the steps involved in the development of Space Shuttle programs?

These actions include signing of a launch services agreement, development of a payload integration plan, preparation of engineering designs and analyses, safety analysis and flight readiness. Finally, there is the actual Shuttle mission, spacecraft deployment or experiment activity, ending in data analysis and distribution.

How do astronauts prepare for launch and landing?

Astronauts prepare for launch, landing, payload and International Space Station operations and rendezvous activities in the Garn Facility. A motion­based trainer simulates the vibrations, noise and views the astronauts experience during shuttle launch and landing.

What do astronauts think about when they get into space?

Astronauts climbing into a space shuttle are typically thinking about lots of things, from trajectories and abort scenarios to systems and when to talk to the launch team and mission controllers. Not to mention the pure excitement that comes with getting ready to go into orbit.
