NASA's guide to near light speed space travel | Human World | EarthSky

Take a couple of minutes to check out this new video from NASA’s Goddard Space Flight Center, released August 14, 2020:

So you've somehow rigged up your spaceship to travel almost at the speed of light? … Before you fly off all willy-nilly, however, there are some important things you should probably know about approaching the speed of light.

* * *

If you take a trip at near the speed of light, you won’t just feel younger when you get back. You’ll BE younger! (compared to friends who stayed behind.) See more postcards like this, from NASA .

The future of deep space travel could come down to tiny solar panels

For decades, scientists have aimed to create the perfect solar panel design for the benefit of all of us here on Earth. Now, research suggests that these supercharged panels could also be a boon much further away from home.

In a new study , a team of German scientists strapped four different perovskite and organic solar cells to a rocket and shot it up into low-Earth orbit (LOE) to see how solar panels perform in non-terrestrial conditions. The flight only lasted seven-minutes but the researchers were able to collect some promising indications of how these panels adjusted to the change.

Is space travel the ultimate status symbol for tech-billionaires? | Tatler

To, 'boldly go where no man has gone before,' could well be the mantra of many a Silicon Valley billionaire, whose fortunes are built on pushing forward with innovative new ideas. But once you've got the billion-dollar-valued company, the superyacht, the endless properties, the private jet, the collection of sports cars and the private island, what's next? Space tourism might be the answer.

50 years after the first Space Race, which saw the USA pit itself against Russia during the height of the Cold War, a second is underway. This time though it's the world's richest men competing - with several vying to be the one to get the first commercial space trip launched.

What CMOs Need To Know About Space Marketing

In October 2012, Felix Baumgartner jumped from a platform into the edge of space in nothing but a spacesuit and parachute. He free fell for just over four minutes, breaking the speed of sound at an estimated speed of 843.6 mph (Mach 1.25). A government space program didn't sponsor the mission. Red Bull sponsored it. The Red Bull logo was on Baumgartner's suit, parachute, and capsule that lifted him to the edge of Earth's atmosphere.

Millennials, Gen-Z, and even the youngest generations tend to value experiences over things. They spend their money on trips, experiences, and exploration. For many, being able to post an adventure to Instagram has more value than buying a new car. Imagine the possibilities to meet that need for adventure where very few have gone - space.

Kellie Gerardi might be the first social media star in space

One of Kellie Gerardi's most popular posts on TikToks (where she has almost 120,000 followers) starts with her looking concerned.

While one hand rests on the side of her face and she furrows her eyebrows, the text above her reads: "Freaking out that my 2yo daughter said 'daddies wear suits to work' and asking "what about Mom?" Gerardi, 31, shakes her head and mouths emphatically, "What do you MEAN?"

The reveal comes seconds later with a music cue — the background changes to an image of Gerardi in an orange space suit while she dances, and the text reads, "But then she says 'and Mommies wear spacesuits.'"

Could We Achieve Interstellar Travel Using Only Known Physics?

The launch of Cassini, on October 15, 1997. This spectacular streak shot was taken from Hangar AF on ... [+] Cape Canaveral Air Force Station, with a solid rocket booster retrieval ship in the foreground. For all of our history on Earth, the only way we've ever reached space is through the use of chemical-based fuels.

But there's no need to restrict ourselves to doing things the way we're doing them right now. With the right technology, we could vastly improve how efficient it is to get a large-payload mass, perhaps even one that carried humans on board, to unprecedented distances across the Universe. In particular, there are four technologies that have the potential to take us to the stars on much shorter timescales. Here's how.
