When will the next Super Blood Moon be seen in the U.S.?

So you know what a blood moon is? It’s when the moon moves into the shadow of the earth (a total lunar eclipse), which causes the moon to grow fairly dark and at the same time pretty reddish as the image below shows.

A red moon, sometimes called a blood moon, takes place during a total lunar eclipse when the moon moves into the shadow of the earth and turns red color and quite dark.

Next, do you know what a supermoon is?

The moon has a slightly elliptical orbit around Earth. Sometimes full moons are further away and appear slightly smaller from Earth. Sometimes full moons are slightly closer to us and they appear larger. When the latter happens it’s a super moon.

The moon’s orbit around the earth is elliptical. The closest approach is called the perigee and the farthest point is the apogee. If there’s a full moon during the perigee, the moon appears larger and is called a supermoon.

A super blood moon simply means when the moon is slightly closer to Earth because of it’s elliptical orbit and it passes into the earth’s shadow. The last one was on January 20, 2019, and will be the only one in 2019.

The next total blood moon lunar eclipse won’t be until May 26, 2021, but it will not be visible from the United States or North America. North and South America won’t see a total lunar eclipse again until May 16, 2022. It will not, however, be a super moon at the same time. For that you’ll have to wait about 19 years.

Do you know if NASA has evidence of alien life?

Yes, I do know the answer to this. It’s no, NASA has no evidence of alien life to date. We only have theories and speculation, but without evidence there is no proof of alien life anywhere else in the universe other than good ol’ Earth.

That being said, most scientist believe life probably exists elsewhere in the universe, but until we actually find even a fossil of a microbe of alien life, there’s no evidence to date.

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.

What will be the main economic gains of colonies on Mars, or the Moon?

You don’t want me to answer this question. You are looking for a great, positive answer that will make the future look bright not only for colonies on these places, but an economic base for those colonies.

Meanwhile, I’m going to say I don’t think there’s much justification even for people walking on Mars when our robots can do it more safely and less expensively and achieve the same or better results…. what to speak of “colonies.” I think it’s almost laughable and mostly just science fiction dreaming.

People may or may not one day walk on Mars at great risk, and some will probably die in the attempt. There is little reason to go there from a scientific point of view other than to say we did, just like we walked on the moon and then went away.

In the meantime, a safer, cheaper way is send our machines to go.

You see, what this is all about is finding life. What scientists want to do is prove that life can evolve elsewhere than Earth – a so far unproven theory. We want there to be life elsewhere because we want to prove that life was not “created” on Earth alone, but life naturally develops from matter when conditions are ideal.

We don’t need “colonies” or economic bases in space to prove that. We just need to find some germs under some rocks or on some moon around some planet in our solar system. For that we just need space vehicles and robots like the Mars Rovers.

Whether we find life or not is anyone’s guess, but it is still science fiction thinking we will colonize anything off planet.

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.

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.
