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

What will happen to the Tesla that SpaceX shot into space?

Bad, bad things, eventually.Chemical bonds in the rubber, plastic and leather will break down within a couple years due to the harsh radiation of space. The tires, seats, dashboard and trim will crumble.The carbon fiber panels will last a bit longer, but eventually the radiation will crumble them as well.The aluminum, glass,

Is SpaceX the only private space company?

There are a lot of private space companies like Blue Origin, Sierra Nevada, Galactic (working with Scaled Composites (the Rutans)) (another friend worked for Rotary Rocket although I had my doubts about them), and even traditional aerospace firms like Boeing (which also bought up its competitors like Rockwell and Hughes) count themselves as

What is the next technological advance that will be as historically significant as man landing on the moon?

The first cloned human.This has been possible for at least 20 years ... but for a variety of reasons, nobody has attempted it.The ability of parents to have children which are clones of themselves will change society (for better or worse) far more profoundly than did the Moon landing.

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

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

What are the possible ways to remove space debris?

Some experts have predicted that in the future Earth will have a ring like Saturn. But our ring will be nuts and bolts and trash. China actually practiced attacking and exploding a space object creating tones of trash for no good reason !Some experts envision a giant

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

What are your thoughts on the NBC article stating the Oumuamua object may have been an alien probe?

I think that they are full of unfounded crap which they have to say because unless it's about aliens, bigfoot, nessie or some other happy crap they figure the average, ignorant doof on the street cannot possibly be interested.They are talking

The NASA Ames Space Settlement Design Competition is one of the most prestigious and biggest aerospace engineering competitions in the world targeted at middle school and high school students, arguably after the International Space Settlement Design Competition.Involving participants from a host

How is New Horizons of NASA powered?

By plutonium 238. Note - this is different from Plutonium 239 which is used in weapons. And it's not a nuclear reactor either.  It's an RTG - Radioisotope Thermoelectric Generator - which is quite different.Plutonium 238 has a very short half

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

When will India get a space station?

India? As in: an own space station? Well, I'm not that informed of the Indian space program, but let me put it this way: India's space program was founded in 1975. That makes it even younger than the Chinese one. China got a man into space in 2003. India isn't even that far (although they are

How many people agree that life can exist on Mars?

Life as we know exists only on Earth as of now. But what constitutes life is still a hot topic for debate. Why are we adamant that all life has to be carbon based? It's hard enough to identify fossilized microbes on Earth. How would we ever recognize them on Mars? How can we know whether some

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

Could intelligent life have existed on Mars?

Unlikely. Mars was dead before any nascent life could have evolved to an intelligent state.Mars has no magnetic field. So, whatever atmosphere and surface water it had has all been stripped away by the solar wind.Consider our own planet. Life emerged about as soon as it could, about 3.5 billion years

Why is the spacing between probes in a four probes device the same?

AIMTo determine the resistivity of semiconductors by Four probe Method.APPARATUSThe experimental set up consists of probe arrangement, sample , oven 0-200°C, constant current generator , oven power supply and digital panel meter(measuring voltage and current).Four probe apparatus is one of the standard and most

Will Mars survive the death of the sun?

One theory is that as the sun leaves the main sequence and becomes a red giant, there is a time when the sun will loose some of its mass.The planets are where they are currently due to the current mass of the sun and when this mass is decreased, the gravity influence of the sun will

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

Is it possible to change the atmosphere of planet Mars to make it habitable?

We should first increase temperature and air pressure, so we can grow crops and walk around without space suit, just breathing apparatus.There are various ways to increase the temperature and air pressure. The best way is to ‘live of the land' and use materials that

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

Does Mars have a blue sky?

It does, but it's not as bright as Earth's, and it's often turned red because of dust.Here's a selection of images put together by Robert Frost. They are all true colour images of Mars' sky.

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

What would happen if Curiosity flipped over?

I don't see how it can tip over.

What has NASA disovered?

Jeez, how long a list do you want? NASA (and its collaborating scientists) are good at wringing every last drop of information out of a mission. They can learn things about a planet's atmosphere just by examining the radio signal that a space probe sends just as it disappears behind the planet.

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

Does India have its own space station?

Does India have its own space station?No India doesn't. India doesn't have manned mission yet. A space station isn't necessary for now. Besides building a space station is not a easy job. It also needs a lot of money. That's why

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.

Should a space agency like NASA, ESA, CSA or Roscosmos (etc.) send a flat-earther to the Internation Space Station? Would there be any benefits of doing this?

No. If you wasted the money to fly a flat-earthier to the ISS you might convince them, if they didn't decide that it was all an elaborate hoax. Even if you did convince the person you took up, all the rest

What is in space below Earth?

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

If space did not occupy air so how can a space shuttle flew in space?

Rockets fly by combustive fuel or exothermic reactions although there are various propulsion systems but all of them contain an oxidizer as there is no air in space! Usually the highly energetic reaction between hydrogen and oxygen acts as a fuel which energizes the particles and these particles

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
