If you were on the ISS, would the view of the stars be completely clear with the lack of atmospheric distortion and light pollution? If so why aren’t there more pictures of it from their pov?

You don’t understand cameras, do you? Well, a quick lesson then. In cameras (other than cell phone cameras), there’s a thing called aperture. When there’s a bright light the aperture has to be small, to let less light in, so you can photograph something like the Earth. This avoids overexposure of the bright objects in your photo. In space, this blacks out the stars.

However, if like the Hubble Telescope, you just look away from Earth at the stars, you see a whole lot more of them than we can see here on Earth.

Here’s a photo taken of the Hubble Telescope from the point of view of the Space Shuttle Discovery. Notice, because the Earth is so bright, we don’t see any stars.

The Hubble Space Telescope (HST) floats gracefully above the blue Earth after release from Discovery’s robot arm after a successful servicing mission.

On the other hand, since the Hubble Telescope points away from the bright light source coming from Earth, we can capture images like these.

Why have humans never been back to the Moon after 1972?

By Richard Muller, Prof. Physics UC Berkeley, author “Physics for Future Presidents”

There never was much value in going to the Moon in the first place, so there was no good reason to return.

When J.F. Kennedy proposed we go to the moon by the end of the 1960s, his goal was to raise American spirits, to return us to a belief that we could win in a competition with the surging Soviet Union (which was not only beating us in space, but even in the Olympics!).

When Kennedy died, I think we were determined to get to the Moon in the now sacred deadline of the late 1960s, to fulfill Kennedy’s dream.

Scientists liked the Moon shot, primarily (this is my observation, not based on a careful poll) because it injected a lot of money into science in space. If the same money had been made available for science in space, but not involving human transport, then most scientists would have favored unmanned experiments, including unmanned exploration of the Moon. It made much more financial sense, but most people (especially at NASA) believed that without the human involvement, the public would not support high levels of spending.

Once we met Kennedy’s goals, of restoring the US spirit and self confidence, then the financial considerations took over. There simply is not much value added by putting men on the Moon; arguably, there is much science value lost. (Science experiments that have to be man-safe are far more expensive.) On the other hand, you’ll notice that not a lot of money has been spent on sending robots to the Moon. Some, and they’ve done some remarkable things, but not the many billions that go along with a man shot.

Instead, we have spent our resources with unmanned exploration of the solar system, with truly spectacular results. We’ve discovered that every moon of every planet appears to be different from every other moon! (That’s only a slight exaggeration.) The great glory of NASA in the last few decades has been its unmanned program. In comparison, the Space Station has accomplished very little. (Again, that is my personal evaluation.)

How Far Can we Drill into the North Pole?

You do realize that there is no solid land over the North Pole, right? There’s ice floating on the ocean, and the ice sheet moves around as it floats. Underneath the ice there is the ocean.

Therefore, to drill into the North Pole you could just drill a hole through the ice until you hit water, or go to the bottom of the ocean and start drilling on the ocean floor.

There’s no specific reason to do so, however, and doing so would be pretty fruitless.

The North Pole has been reached by walking, by ice-breaker ship and by airplane. In the image below, a woman traveling on the Russian nuclear icebreaker Yamal holds a sign marking the North Pole, however, because the ice drifts, the sign also drifted away from the pole.

Sadly, there’s no Santa at the North Pole.

The First Day of Spring

Never happened.

There is no first day of spring. There is a spring equinox. This spring of 2019 it will be March 20th at 4:58 PM Central Daylight Time (future tense as of time of writing). Adjust accordingly for your time zone.

Equinox is when the days and nights are of equal length. There’s two equinoxes: Spring and Autumn. It happens to be when Earth passes a particular point in orbit around the sun. This year, that moment will be at March 20th and 4:58 PM CDT. After that moment we enter the spring season, and days in the Northern Hemisphere will officially be longer than nights.

I recognize this is the Internet and many will read this after the fact, but the principle remains the same. There is no official first day of spring. There is only the moment of the spring equinox.

Skinny Dipping in the Adirondacks

When I was a young boy we used to go hiking in the Adirondacks. My father would sling an ax over his shoulder and my mother and her three boys would set out on an adventure in the mountains.

We would come across leantoos. This is basically a wooden shack with a roof and one side open to the elements. It was shelter provided by the park service. We’d set up camp and spend the night.

Typical leantoo in the Adirondack Mountains.

I was the youngest of three boys and although these were really cool adventures, my brothers were 8 and 10 years older than me, so I used to complain a lot about all the walking.

Some of the places we visited had water falls and pools of deep, cold and fresh water. Because nobody thought to bring bathing suits, they went skinny dipping.

Now, don’t try. They’re watching from the sky.

Specialized spy satellites that can photograph things as small as a fist are flying above us. I can even see the junk in my backyard by searching Google Earth, and word is the governments have even better satellites flying at over 17,000 mph about 200 miles above.

Why might there be no life in other planets that are located in the Goldilocks Zone?

If you ascribe to various religions, then because God created life on Earth, not elsewhere.

Aside from the religious connotation, we haven’t found evidence of even a fossilized microbe from another planet to date. In fact, there is no proof life exists anywhere else other than Earth.

Now for those of us who prefer science, it’s likely life does exist somewhere else. We just can’t prove it yet. If we could prove it, then it would challenge the theory of creationism.

GPS Block III on Hold

Since GPS achieved Fully Operational Capability on July 17, 1995, GPS has become an essential navigational tool for civilians and military alike. Keeping the system up-to-date has proved to be a problem. Originally the system was supposed to be up and running in February of 2016 but has been delayed at least until 2023.
The latest iteration of the GPS satellite array is called GPS Block III. These satellites must be launched (and will greatly increase navigational accuracy) in order to keep the Navstar global positioning system operational.
The satellites have already been built by Lockheed-Martin and consist of ten new, advanced satellites to be launched into orbit by SpaceX Falcon rockets. The hold up is the U.S. government wanting to make sure the hardware actually gets up there as they independently seek to confirm the safety and reliability of the SpaceX rocket systems.
The new GPS satellites will boost additional easier to track signals for civilian navigational uses and a Military code (M-1) providing anti-jamming security use for the military.

Why does the moon revolve around the earth?

It just moves forward. The moon isn’t stationary. It has inertia and no atmosphere in space to slow it down. It just goes. As it moves forward, the gravity of Earth tugs on it and it falls, but because it’s moving forward it misses Earth as it falls and goes around, again and again. That’s called an orbit.

Simply said.

Why doesn't anyone else besides me believe in time traveling?

I don’t know the answer to your question. However, consider this. We are not standing still. In time the Earth rotates around it’s axis, the Earth also rotates around the sun, the sun rotates around the galactic center and the galaxy is merging with Andromeda.
We are therefore moving at hundreds of thousands of miles per hour in space. Fast forward 10 seconds and you will find yourself in outer-space without a spacesuit!
