How many times has Nasa been to the Sun?

Answer 1

0?

Answer 2

NASA has never sent a probe to the sun as far as I know. It could never reach the sun, it would burn up long before reaching the physical sun. However, when I worked at JPL years ago I did hear a rumor of a spacecraft which was accidentally put into an orbit which would bring it so close to the sun that it would burn up. I don't know how true this is, but I do know that there were many errors in NASA's space program that were not common public knowledge.

Answer 3

None. But not necessarily because the sun itself is too hot.

The surface of the sun is around 5000-6000 degrees. If this were the only thing we needed to worry about we could actually orbit a probe fairly close to the sun.

The big problems are gravity, magnetic, radiation, and the chromosphere. The gravity field of the sun is much stronger than earth's and would crush anything we could make very quickly. The chromosphere is few million degrees kelvin. That doesn't just melt metal, it turns it into plasma. The magnetic field strengths on the surface of the sun are incredibly strong. Strong enough to rip apart any metal containing object. And lastly, the amount of radiation is intense. Any probe close to the sun would be rendered completely useless in moments.

It's a challenge just making probes that can survive in a Mecury orbit, let alone anything closer than that.

That being said, NASA has launched numerous probes that observe the sun from a safe distance.

Answer 4

As far as I know, NASA has never sent anyone or anything to the Sun. Such a mission would undoubtably end in dismal failure due to the excessive heat and radiation the mission vehicle would encounter only partway along its journey to the Sun. Anything containing metal would be vaporized in a very short time period.
Most observations of the Sun are carried out at a very safe distance.

Answer 5

Nasa has never been to the Sun.

Answer 6

all info which nasa has learned about the sun is collected by an instrument which measures the intesity of light given off which tells various things of that part of the star such as rate of movement if any at all and the heat and the density of that matter

Answer 7

Only once. They sent you. No, seriously, are you a moron? The sun is really hot and would burn the NASA shuttle. Even Superman stays away from the sun.

Answer 8

NASA has not been to the sun. Impossible, they have been to the moon. I hope you are joking about your question

Answer 9

Never!!!The sun is too hot for anything to survive there. If a satellite actually goes there (or attempts to) it will burn before it even reaches the surface. I think you are thinking of the moon or Mars or something.

Answer 10
