Spacecraft that will operate within the inner solar system are generally equipped
with solar (photovoltaic) panels, which use sunlight to generate electric power.
Those that will spend most of their time in the outer solar system, or leave the
solar system entirely, will carry nuclear reactors to generate electric power.
The electric power runs the instruments, computers, and communications on the
spacecraft. But in most cases, electric power doesn't provide the forces needed for
navigation. Mid-course adjustments of attitude and trajectory are made the old-
fashioned way ... with rocket engines, or thrusters that poof out little puffs of gas.
Both of those run on fuel that's carried aboard the spacecraft at launch. When it's
gone, it's gone.
What else can I help you with?
Why do spacecrafts lose their large fuel tanks and booster rockets once they have left the earth's surface?
Spacecraft discard their fuel tanks and booster rockets once they have left Earth's surface to reduce weight and improve efficiency. Once the fuel in the tanks is consumed and the booster rockets have propelled the spacecraft into orbit, they are no longer needed and would only add unnecessary weight and drag. By discarding them, the spacecraft can operate more efficiently and maneuver in space more easily.
What are the disadvantages to solar energy?
Some of the disadvantages of solar energy are the means of collection and the necessity of the sun. Solar panels can be very fragile and easily broken and they do not operate at peak efficiency unless aligned properly.
How do spacecrafts take off and return to Earth safely?
Spacecrafts take off using powerful rockets that provide enough thrust to overcome Earth's gravity. To return safely, spacecrafts need heat shields to protect them from extreme temperatures during reentry, parachutes to slow down the descent, and landing systems like airbags or rockets to ensure a soft landing. Additionally, careful planning, monitoring, and coordination with ground control are essential for a successful mission.
How does the sun supply living things with energy they need?
The sun emits light and heat energy through a process called nuclear fusion. Plants use sunlight during photosynthesis to convert carbon dioxide and water into glucose, a form of chemical energy. This energy is then transferred through the food chain as animals consume plants or other animals.
Do you need to conserve solar energy?
Yes, it is important to conserve solar energy because it is a renewable resource that is not limitless. By using energy-efficient technologies and practices, we can maximize the benefits of solar energy and reduce our overall energy consumption. Conservation also helps to protect the environment by reducing the need for fossil fuels.
What does a toy need to obtain energy?
Toys are not alive so they don't need to obtain energy. You provide energy to a toy by using batteries or electricity.
Where organisms obtain the energy they need?
hydrosphere
Why does a plant need to plant glucose's?
To obtain its energy.
How dos animal get the energy they need to live?
consumers eat producers to obtain the energy they need to survive
How do you obtain the resources you need to survive?
They obtain energy through the air and obtain oxygen through their gills to breath
Where do you obtain the energy you need to complete everyday tasks?
You obtain the energy from the food you eat, when you breath your body breaks down the food and turns it into energy that it can use ATP molecules.
How might this affect the ability of animals to obtain the energy they need to live?
There are many things that could affect the ability of animals to obtain the energy they need to live. Having water is a good start.
How you depend on the sunlight to obtain energy?
because they need to and it is the cycle of life
How do you think these bacteria obtain food and energy?
They are anaerobes and do not need oxygen. They are consumers and make energy by fermentation.
Do you need a valid driver's license to obtain a motorcycle license in Pennsylvania?
Yes you can, you need a provisional license inorder to but you can operate a motorcycle in new jersey
Why do plants obtain energy from the sun?
they need food and that's wat they use it for
Does cellular respiration occur in plants?
Plants also need energy. So they obtain energy through respiration
