The astronaut is connected to the spacecraft by what?
The astronaut is connected to the spacecraft by a tether or umbilical cord. This ensures they remain secured to the spacecraft while performing spacewalks or other external activities. The tether also provides communication, power, and life support systems to the astronaut.
What powered the Apollo 11 spacecraft?
The spacecraft's electrical power came from storage batteries (also called fuel cells), carried onboard. They generated a maximum of about 2300 watts. The fuel to launch the spacecraft was liquid oxygen (with kerosene, and liquid hydrogen for the upper stages), with nitrogen tetroxide to steer, adjust and make course corrections.
Are solar batteries commonly used by NASA?
Solar cells are commonly used on spacecraft but because a spacecraft might spend a considerable amount of time in the dark they also have fuel power. They most obviously use oil based fuel to launch the spacecraft into space.
What is the plural for spacecraft?
The plural for spacecraft is spacecraft.
How much power was used by the transmitter on the Voyager spacecraft to communicate with Earth?
The transmitter on the Voyager spacecraft uses about 23 watts of power to communicate with Earth, which is equivalent to the power used by a typical refrigerator light bulb. This is necessary because of the vast distance and weak signal strength encountered in deep space communication.
Why are fuel cells used in spacecrafts?
They supply power to the spacecraft during missions.
What provids a cushion and prevents wear and tear in a joint?
ligaments;] cartilage A+
What is the function of the carapace on a crayfish?
The caraspace protects the gills and provids a water cannel.
What provides power for spacecraft?
There are many different types of power supplies for spacecraft. By far the most common is solar power (a solar array with a battery array). Solar power looses efficiency quickly the farther from the sun a spacecraft goes. Most deep space spacecraft use a thermo-nuclear battery. These batteries can last for decades. The voyager spacecrafts, launched in the 1970's, batteries will last until the mid 2020's!
Why is environment education provids to engineers?
That would depend on the school, the course, and the specialization of the education.
What provids 95 percent of the worlds energy?
The world's 70% of the energy comes from coal or fossil fuel based power, most of the countries currently use Nuclear as their leading power supply, one such example is France which produces 90% of its energy from Nuclear fuel
Why are fuel cells so useful in spacecrafts?
They supply power to the spacecraft during missions.
Power souce of the voyager 1 and 2 spacecraft?
"Spacecraft electrical power is supplied by Radioisotope Thermoelectric Generators (RTGs) that provided approximately 470 w of 30 volt DC power at launch. Due to the natural radioactive decay of the Plutonium fuel source, the electrical energy provided by the RTGs is continually declining." (From the http://voyager.jpl.nasa.gov/spacecraft/spacecraftlife.html page)
What type of spacecraft operates by a renewable energy source one that will not run out?
Solar-powered spacecraft operate using solar panels to convert sunlight into electrical energy, which can then power the spacecraft's systems. Solar power is a renewable energy source that will not run out as long as the sun continues to shine.
The astronaut is connected to the spacecraft by what?
The astronaut is connected to the spacecraft by a tether or umbilical cord. This ensures they remain secured to the spacecraft while performing spacewalks or other external activities. The tether also provides communication, power, and life support systems to the astronaut.
How does a spacecraft launch from earth?
the fuel needed is huge but you need to take in the power and the amount of thrust
What are the problems of unmanned spaceflight?
Finding ways to power the spacecraft or probe is one problem of unmanned spaceflight. Unmanned spacecraft have limited abilities and they don't have the ability to do follow up testing.
