Have we ever sent space probes to examine our Sun?

Adding to Alec Cawley's answer to Have we ever sent space probes to examine our Sun?the two Helios (spacecraft) - Wikipedia were launched in 1974 and 1976 to study the Sun. They are no longer operational, but they were notable because they are

How fast we will be able to space travel in 50 years given the current technological knowledge we have today?

In 50 years, in a nutshell, manned missions to Mars, a possible Moon base, and the beginnings of asteroid mining to include not only near Earth asteroids but also the main asteroid belt between Mars and Jupiter are all possible. Possible

What was the effect on Tesla of having one of their cars sent into space by SpaceX?

Tesla does not advertise, yet 450,000 people put down $1000 deposits to buy the Model 3, a car no one would even test drive for 2 more years. The effect on Tesla from Elon's roadster being sent into space was more word of mouth, more people test driving Tesla cars and more orders for new cars.

Does anyone really believe Space X is going to space?

To hell with science, let's talk business: each satellite costs >$100M to build, and about that much to launch into space. Any company willing to put out $200M will want that money back somehow. Paying SpaceX to dump a $100M satellite into the ocean is not

Can you blow my mind with a space fact?

How about this:Stand outside, perfectly still, and look around you. Leaves flutter in the breeze, cars drive by, birds flit through the air, and yet you are perfectly motionless amidst all that activity.But are you really? At that very moment, you are standing on the

Why are space ships called spaceships?

Why are space ships called spaceships?Because they are ships (containers for people or cargo) that travel in space.

When was the first Mars landing?

Q: When was the first Mars landing?A: The first attempt was in 1962 by the Soviet Union. It was a failure: the unmanned spacecraft never left Earth orbit.The first somewhat successful attempt was also by the Soviet Union in December 1971. This time, the unmanned lander Mars 3

Is it true that NASA is planning on sending Alyssa Carson to Mars, and that she might be the first human there?

This is not true that NASA is planning to send her to Mars.First of all I never heard of her.Second, she calls herself a

How long would it take to travel to the super earth Kepler-452b?

Using current technology of rockets and spacecrafts the trip is impossible, no matter what is on the drawing boards.  The trip itself is not impossible for humans; just using current space technology makes it that way.  The only other thing that makes it impossible, is physics silly solution to real teleportation; the Star Trek methodology of scanning/decoding

Is it possible to plant life on another planet?

You have raised an important and interesting point.Planting life (microorganisms to start) with is pretty simple given the fact that man landed on moon way back in 1968 or so and now man has send probes that are bringing back soil/rock samples etc

Why can't NASA send people to Mars?

There are thousands of problems for that. First of all Mars doesn't have what it takes to sustain life. I am not talking about oxygen,that can be solved​ by spacesuits but the main problem is pressure on Mars is negligible compared

What would be a way to explore others sun systems?

Only by big telescopes, anything else is unfeasible. Reaching a different stellar system will take to the order of ten thousand years. Our civilization won't exist anymore on that time scale. Also currently there exists no technology that will survive a hundred centuries. It is inconceivable that such a technology will

Why cant astronauts confirm that the world is round?

They cannot confirm something that is obviously not true, that would be folly.  (edit, due to Poe's law, pointed out to me in the comments, this answer is for humour.)The earth is an oblate spheroid, and they confirm this every single day of their boring

Why can't you see the Sun or stars in all of the outer space pictures they show us?

Because of the immense distances involved, one exposure won't capture detail for all of the above at once. The farther away we are the less light hits us from a given source. An equivalent scenario would be to wait until the sun is setting over your house. Then go inside, turn on

Does being on Earth count as being in space since the Earth is in space?

No. Technically speaking, the concept of space is better defined as

How long can an astronaut stay in space without oxygen?

An astronaut can survive in outer space without oxygen,but for barely a few seconds.After about 15 seconds,he/she will start losing consciousness from lack of oxygen.That's a totally different case from Earth.On earth you can easily survive a few minutes without breathing because there is no vaccum on Earth

Why do we send people into space?

Following WWII, we had German and American rocket scientists with not a whole lot to do that the US didn't want going over to the Soviet Union. We also had a growing stable of test pilots and a few people in the US public who

What can astronauts see in outer space that we cannot see from here on Earth?

What can astronauts see in outer space that we cannot see from here on Earth?With the aid of their instruments, they can see the electromagnetic spectrum which is filtered out by the atmosphere, that does not reach the surface of Earth.Remote SensingSome types of electromagnetic radiation easily pass through the atmosphere, while other types do not.The ability

How long would it take to travel across the Milky Way at the speed of light?

It depends on who you're asking.If you want an answer to this, you typically start out with a Minowsky Diagram. It's relatively easy to construct-two perpendicular lines with the vertical labelled ct for timexlightspeed and horizontal labelled x, like in a graph, and you're almost done. For convenience's  sake we'll measure distance, x, in light seconds-

In deep intergalactic space, would an astronaut be able to see his own hand?

It depends what you mean by "deep space". If you were far from Earth but the same distance from the sun that Earth is, the sun would be rather brighter, since the atmosphere scatters some light. The further from the sun, the dimmer.

What is in space below Earth?

What a fascinating question involving just six words! In fact, two of the words (

What's easier: getting a spacecraft to space, or keeping a spacecraft in space?

Of-course getting the space craft in the space. Have a look on any rocket, i guess 95% mass is the rocket and its fuel. Review following figures for Space Shuttle obtained from Ask an AstronomerThe Space Shuttle weighed 165,000 pounds empty. Its external tank

Why does a space shuttle fly upside down?

An essential issue in the stability of a rocket is the location of the center of mass relative to the direction of the thrust vector. Most rockets (certain models of Atlas being notable exceptions) are symmetric around the longitudinal (roll) axis so the (combined)

Why is space so vast?

Bear with me and try to wrap your head around this! We've all heard there are more stars than grains of sand on all the beaches on all the beaches on earth. The University of Hawaii has estimated the Earth has roughly 7.5 x 10 to the 18th power grains of sand. That is

What is the next realistic and yet exciting milestone in space exploration?

As humdrum as it sounds, the next big milestone is proper reusability. When Spacex successfully reuses a Falcon-9 first stage, they recover nine out of ten expensive engines. The cost of a kilogram to orbit might reduce by as much as 90% (the unrecovered second stage

Did NASA ever sent an Indian into space?

Yeah. Kalpana Chawla, Rakesh Sharma, Sunita Williams.

What's wrong with NASA?

There is nothing wrong with NASA's unmanned programs.   Unfortunately NASA does not  have  rock steady funding.   They are at the mercy of a Congress that blows hot and blows cold.  Also program goals  are  politically encumbered.    NASA has the problems of any large corporate entity which has no market power of its own and must depend

Does NASA have plans to send a manned mission to the Moon?

NASA has an exciting new vision of future spaceflight-the return of humans to the moon by 2020 in preparation for visits to Mars and possibly beyond.Moon missions are essential to the exploration of more distant worlds. Extended lunar stays build the experience and expertise needed for the long-term space missions required to

What do we call unoccupied space in outer space?

One would assume there's only one term for such a phenomena, yet everyone so far has suggested different terms. Allow me to add two more:Darkspace*Intergalactic voidAnd a bonus, less accurate:Outer spaceI would go with Intergalactic space though, that's the space between galaxies. In contrast, the space

What spaces agencies like NASA and ISRO are doing to curb space pollution?

It is actually littered with waste, some of which were caused by human activity.Debris in space is called space junk or orbital debris because they orbit the Earth. They are made up of items such as used-up rocket stages, loose fragments from rocket explosions and collisions, launch canisters, dust and paint flakesESA,

How long would it take a spaceship traveling at 2.5x the speed of light to travel from Earth to the edge of the universe?

Disregarding the fact that it is impossible, the radius of the observable universe is roughly 50 billion light years. As seen from earth i twould take around 20 billion years to reach the end of the currently observable universe.Although after 20 billion years the radius of observable universe as seen from earth would have increased by 20 billion light

How much damage would be sustained by an aircraft carrier upon entering the earth's atmosphere from outer space?

An aircraft Carrier isn't build with the heat shields needed for re-entry, nor is it build for flying. Besides the obvious destruction from impacting the surface, it would have massive amounts of it vaporized off from the heat of re-entry, it could possibly even

Is faster than light speed travel possible in a scenario in which a ship travels at near light speed?

There is no fallacy here, just that you have put an incomplete hypothesis.Here's how it works -For an observer on planet B (let's call her Mary), it's pretty simple. Let the time duration of the event ( Joe departing from A, and reaching B) from Mary's frame of reference be T; and the distance as seen

How long would it take a spacecraft to travel one light-year?

If the spacecraft is travelling at speed of 1,00,000 km/hour then it would take 10,000 years to travel one light year. So assume one entire human life of 100 years can travel 1% only.Consider, if each generation marries at age of 25, it would take 400 generations to reach one light year.

Is this a photo of a space shuttle leaving Earth?

It is a photo of the launch of the Shuttle on STS-134 taken from the Shuttle training aircraft. (the STA were modified Gulfstream business jets) Note the posted photo seems to have been modified a bit. More pictures in the series are available here: STS-134 Flight Day 1 Gallery

What is the present easiest method for interstellar travel for human beings?

There isn't one. Period.There is no presently available technology which could permit any type of interstellar travel which a human would survive. A human's descendants several generations removed might arrive intact, but no human who was aboard when the journey began would be alive when it reached even the nearest interstellar candidate.Using present technology, interstellar travel would take

Why has NASA been the only agency able to explore the outer solar system so far?

Well, this isn't quite the case.It's wrong to say that no other exploration has been done by anyone but NASA or ESA.And Russia and China having big budgets doesn't really mean they're the premiere space agencies or even will be. Budget isn't everything where this dynamic and malleable space

Is space exploration a waste of money?

The amount of money that countries spend on space exploration is actually not that much in relative terms. I will use the U.S. as an example because they spend the most. NASA receives about 0.5% of the whole federal budget. Another way to think about this, is that

How to put a space shuttle in orbit and somehow aligned to reach ISS

There's people who know how to do that... they're called Rocket Scientists.Takes a better than excellent knowledge of orbital mechanics, math, and physics.

Is NASA still going on space missions?

Either you're a troll or you're unbelievably gullible. Obama no more sold NASA to Russia than Roosevelt sold the FBI to Hitler. He can't. It's a government agency, it's not for him to sell. NASA has numerous space missions under way at this very moment. It has crew aboard the International Space Station, and robotic craft

How long does it take earthshine to travel from the earth to the moon?

Come on. Simple math. Light travels at 299,792,458 meters per second. Earth is 384,400,000 meters from the moon. So it would take 1.28222038 seconds for the light to bounce off your forehead and be reflected to the moon. Fast enough that Steven Tyler wouldn't miss a thing making that journey.
