What is the harmful effects of space travel?

Radiation is a potential hazard of space flight.

On Earth, our atmosphere and magnetosphere help to protect life from solar & cosmic radiation,

When people travel above the atmosphere, or beyond the magnetosphere, they are exposed to high levels of radiation.

There are ways to protect astronauts and cosmonauts from radiation, but shielding is very heavy and for every pound of material placed into orbit, it cost several thousand dollars. So a balance has to be reached: cost/benefit.

Weightlessness for a short duration flight won't cause too many problems, but for long duration flights, weightlessness can cause a loss of bone mass and excessive atrophy (wasting) of many of the muscles.

Why the period between 1980 and 1989 is important in the history of space exploration?

The period between 1980 and 1989 was important in the history of space exploration because of significant milestones achieved during that time. Examples include the launch of the Space Shuttle program in 1981, the successful deployment of the Hubble Space Telescope in 1990, and the first Martian landing with NASA's Viking missions in 1976. These developments marked advancements in space technology, scientific discovery, and international cooperation.

What would happen if space shrunk?

Since you are part of space and space is a part of you, you would also shrink,

and without performing some highly sophisticated Physics experiments, you

would never notice that anything had happened. (Your ruler and your clock

would also shrink, so measuring a change in anything would be challenging.)

How does the space probe voyager aids in space exploration?

Voyager probes provide valuable information about the outer planets, their moons, and the interstellar space beyond our solar system. They have revealed new insights into the gas giants, their rings, and their moons, and continue to explore the boundaries of our heliosphere. They also carry a golden record with sounds and images from Earth as a message to any potential extraterrestrial intelligence.

Can compressed air propel an object in outer space?

I think it could and in outer space you would keep going faster and faster you could even beat the speed of light after a few years.Just hook up solar panels to air conpressers and run it out the rockets and need no fuel.We should biuld a space craft and travel to the nerest earth like planet,we could me on new planet in 20 years or so.

================================

Answer #2:

Answer #1, above, describes a brilliant, innovative, groundbreaking plan for

interplanetary travel. However:

-- You could not beat the speed of light, after any length of time. There's

a lot more to it than to just keep on pushing for a long time.

-- Solar panels could certainly run the air compressors, but you still need

something to compress, and there's no air in space. So if you want to use

compressed air, you need to bring all the air along with you. (And since you

want to keep it in tanks that are as small as possible, it'll already be highly

compressed before you leave, so you won't need the air compressors, and

you can just leave them behind.)

-- Solar panels don't work worth beans when you get farther away from the sun.

-- Even if the nearest star has an Earth-like planet, if you want to be there

in "20 years or so", you'd have to average 21% of the speed of light for the

whole trip. Just to reach that speed, you'd have to keep blasting 24/7 with

your rockets or your air compressors or whatever, for almost 40 days !

You could accelerate faster than that, but you'd have to exceed 2 G's, which

over any extended period of time would most likely wipe out the passengers.

And that's just to reach the nearest star.

How many humans can a rocket carry?

It depends on the size and type of the rocket. Some rockets like the SpaceX Crew Dragon can carry up to 7 astronauts, while others like the NASA Space Launch System can carry up to 4 astronauts for deep space missions.

How much equipment can a space station hold?

A space station can hold a wide variety of equipment and instruments necessary for conducting scientific experiments, life support systems, communication devices, and navigation equipment. The specific amount of equipment a space station can hold depends on its size, design, and purpose. The International Space Station, for example, has a pressurized volume of approximately 388 cubic meters, providing enough space to accommodate a significant amount of equipment for various research activities.

What is the temperature of a aldebaran star?

The surface temperature of Aldebaran, an orange giant star, is approximately 3,900 Kelvin (3,626 degrees Celsius or 6,540 degrees Fahrenheit).

Does Jupiter have bumpy spots?

Yes, Jupiter has bumpy spots on its surface caused by different features such as storms, clouds, and atmospheric disturbances. The most notable bumpy spot is the Great Red Spot, a massive storm larger than Earth that has been raging for centuries.

Can deaf people become astronauts?

They probably could, but up until now, none of the world's national space agencies

has begun to accept deaf applicants for astronaut training. Note that the customary

continuous communication with ground controllers might become an issue, although

in principle, it could be accomplished by 'texting'.

A few other conditions which, as of the present time, constitute automatic show-stoppers,

include, but are not limited to, vision impairments all the way from corrective lenses to

blindness, partial paralysis, lack of both a college degree and piloting experience, morbid

obesity, paranoia, mean or lower intelligence, tendency toward motion sickness, lack of

a level of ambition bordering on OCD, spinal stenosis, BPH, chronic renal calculus, etc.

What does the size of a galaxy mean?

The size of a galaxy refers to its physical dimensions, typically measured in terms of its diameter or radius. Larger galaxies can contain billions to trillions of stars, while smaller galaxies may have fewer stars. Galaxy size can also provide clues about its age, structure, and evolutionary history.

What is the equipment a space station may carry?

A space station may carry equipment such as scientific instruments for research, communication systems, solar panels for power generation, life support systems for astronauts, docking ports for incoming spacecraft, and robotic arms for maintenance tasks. Additionally, they may have exercise equipment for crew health and various tools for repairs and experiments.

Why is it less expensive to launch an interplanetary spacecraft from the International Space Station in earths orbit than from earth itself?

We've never made an interplanetary spacecraft, but those who argue that it would be best to start from high orbit (like at the international space station) argue that the amount of rocket fuel needed to leave the surface would be far greater if done all at once instead of in pieces. Rocket fuel is expensive.

How does astronomical research and space exploration occurs?

Astronomical research and space exploration involve telescopes, satellites, rovers, and spacecrafts to observe, study, and explore objects in space. Scientists collect data, conduct experiments, and analyze findings to learn more about the universe. Collaboration between various space agencies and institutions worldwide is crucial in advancing our knowledge of the cosmos.
