Balloon Cams Will Offer Unparalleled Views of the Total Solar Eclipse

The August 2017 total solar eclipse should be visible to some degree from just about everywhere in the continental United States—that is, if the weather cooperates. But now, even if it doesn't, everyone will be able to watch along, thanks to livestreamed video from balloon cams drifting miles above the Earth.

Astrophysicist Angela Des Jardins of Montana State University (MSU) got the idea to monitor the magnificent cosmic event from the air after reading about an airplane pilot's flight through the path of a 2013 eclipse. She thought her students might enjoy the chance to get an up-close look for themselves.

But what started as a class project quickly, well, ballooned. At last count, teams from more than 50 other schools had joined the Eclipse Ballooning Project. The core of the work remains close to home; MSU students have designed, built, and tested the equipment, and even offered multi-day training for students from other schools. Undergrads in the computer science and engineering programs even created the software that air traffic controllers will use to track the balloons on the big day.

The next step was to get the balloon cam footage to a larger audience. Seeing no reason to think small, Des Jardins went straight to the source, inviting NASA and the website Stream to join the fun. The space agency is now beefing up its website in anticipation of 500 million livestream viewers.

And what a view it should be. The balloons will rise more than 80,000 feet—even higher than NASA's airplane-mounted telescopes.

"It's a space-like perspective," Des Jardins said in a press statement. "From that height you can see the curvature of the Earth and the blackness of space."

Online or outside, Des Jardins says viewers can expect a kind of "deep twilight, with basically a 360-degree sunset" during the eclipse.

She urges everyone to get outside if they can to see the event with their own eyes, but expects the balloon cams will deliver something really special.

"On the ground, an eclipse just kind of happens to you. It just gets dark," Des Jardins told New Scientist. "From the air, you can see it coming and going. I think that perspective is really profound."

Now You Can Train to Be an Astronaut on Your Smartphone

Just because you don't work for NASA doesn't mean you'll never make it as an astronaut. In the world of private space tourism, a little training could be all you need. And there's an app for that.

Space Nation, a Finnish space tourism startup, recently launched Space Nation Navigator, which the company touts as the first astronaut training app in the world. The app aims to train future space travelers using games, quizzes, and fitness challenges that fall into three categories: "body," "mind," and "social."

Each of the challenges is tailored to help you develop the skills you'd need to survive in space—even the mundane ones. One mission is called "Did you clean behind the fridge?" and is designed to highlight the unpleasant chores crew members on the ISS have to do to keep things tidy. There are "survival" quizzes that test your knowledge of how to properly build a fire, read a map, and dispose of your poop in the forest. The app also plugs into your smartphone fitness data so that you can participate in athletic challenges, like a 650-foot sprint designed to train you to escape a meteor impact zone.

"Space Nation Navigator offers a way for anyone, anywhere to have a 15-minute astronaut experience every day. These astronaut skills—team building, problem solving, positive life hacks—are not just vital to survive in space," Space Nation CEO Kalle Vähä-Jaakkola said in a press statement. "They are also crucial in your daily life."

New challenges are added to your queue every few hours, and you can compete against other users for high scores. If you get enough points, you can become eligible for real-life training experiences with Space Nation, including a trip to Iceland. In 2019, Space Nation plans to hold an international competition to find one astronaut that the program will send to space.

If you're going to start training, we suggest you take some of the tests Project Mercury applicants faced back in 1958 to see how you'd stack up against the first NASA astronauts.

Big Questions
If Earth is Always Moving, Then How Do We See the Same Constellations Every Night?

Luis Medrano:

6700 mph is nothing in cosmological speeds and distances. Constellations are freakin’ far away.

Get in a car at night and drive on a straight road, then look at the moon. The angle of the moon in respect to your point of view doesn’t change; it seems like the moon is following you wherever you go. Meanwhile, things that are really close to you—like electric poles, roadside buildings, and trees—seem to fly by really fast.

The effect is known as parallax. Things that are close seem to move faster and “travel more distance” (not really) than things that are far away.

In the video above, there are several objects in perspective. The light in the center, which represents the sun, was placed so far away you can barely see it move.

The sun is only eight light-minutes away; that’s 146 million km on average. At human scale it seems like a lot, but in cosmic distances it is nothing. Orion, for example, has stars that are from 243 to 1360 light years away from us. Imagine traveling at the speed of light for 1360 years. That’s how far these stars are. And these are not even the farthest stars. Some stars are Giga-light years away from us.

Now, with the proper precision instruments you can indeed notice the parallax in distant stars, just not with the naked eye. Furthermore, our solar system has moved so much since the early days of astronomy and astrology, the constellations do not correspond to the early astrology maps. The constellations appear shifted.

As a free info nugget: In case your life is ruled by astrology, whatever sign you think you are, you are not.
