Subscribe to Our New Weekly Email Newsletter Written By Fraser

It’s been almost 19 years since I founded Universe Today, back in March, 1999.

Back when I started, it was a primarily an email-based newsletter with an archive version on the web where people could read it if they wanted to.

The technology was pretty rudimentary at the time, so I had to do everything by hand, sending out a BCC email to thousands of people every day, eventually finding other email mailing list providers. At some point, I shifted from commentary and summaries to full on reporting on space news. And at that time, automated tools arrived that would take all the stories you wrote in a day, bundled them up and sent them out via email to a list of subscribers.

That was great and convenient for me, but it didn’t make for the best experience. It lost its soul.

A couple of months ago, I decided to return to my roots and continue maintaining a weekly email newsletter that summarizes some of the top stories that happened this week. And not just stories from here on Universe Today, but stories from across the Universe of space journalists and websites, including Space.com, Ars Technica, Ethan Siegel, Brian Koberlein, TheVerge and many more. I see more amazing things out there than we could ever report on. I figured I might as well share it.

Each edition of the weekly newsletter comes out on Friday, and is hand-written personally by me, and includes a few dozen summaries and links to stories on Universe Today and beyond, as well as cool pictures, videos, and astrophotography.

Here’s an example of what it looks like.

It’s SPAM free, I won’t sell the email addresses to anyone. There aren’t any ads in them, although I’ll occasionally promote books, trips and other projects I’m working on, but tastefully, I promise.

And you can unsubscribe any time you like.

If that sounds good to you, go here and sign up.

Weekly Space Hangout: Feb 14, 2018: Joe Pappalardo’s “Spaceport Earth”

Hosts:
Fraser Cain (universetoday.com / @fcain)
Dr. Paul M. Sutter (pmsutter.com / @PaulMattSutter)
Dr. Kimberly Cartier (KimberlyCartier.org / @AstroKimCartier )
Dr. Morgan Rehnberg (MorganRehnberg.com / @MorganRehnberg & ChartYourWorld.org)

Special Guests:
Joe Pappalardo is the author of the new popular science and technology book, Spaceport Earth: The Reinvention of Spaceflight (The Overlook Press; Available Now). In it, Pappalardo “tackles the ever-changing, 21st-century space industry and what privately funded projects like Elon Musk’s SpaceX mean for the future of space travel.” (Foreign Policy)

Spaceport Earth takes readers on a tour of these high-stakes sites as Pappalardo examines how private companies are reshaping the way we use, intend to use, and view space travel, not solely for scientific exploration but for increasingly more general travel. Visiting every working spaceport in the United States and rocket launches around the world, Pappalardo presents a travelogue and modern history of spaceflight — where the industry is now and what’s on the horizon for explorers and consumers alike—in Spaceport Earth.

There is a car, in space. Launched by a rocket with reused parts that landed back on Earth by a billionaire who wants to colonize Mars.

Update: It looks like the center booster didn’t make the landing. It couldn’t light all its engines back up and it hit the droneship hard.

In the last hour or so, SpaceX successfully completed the first liftoff of the Falcon Heavy rocket. This is a beefed up version of its successful Falcon-9 rocket, where three boosters are strapped together, firing 27 Merlin engines simultaneously with the capability of launching 54 tonnes of cargo into space.

The Falcon Heavy is now the most powerful rocket currently operating on Earth, by a factor of two.

On board the Falcon Heavy was Elon Musk’s choice for a test mass. An appropriate amount of weight that will demonstrate the Falcon Heavy’s ability to carry cargo into space: his car. Specifically, his Midnight Red Tesla Roadster. At the driver’s seat is a dummy named StarMan wearing a prototype of the SpaceX spacesuit that astronauts will wear when the Dragon capsule starts delivering crew to the International Space Station.

The launch was delayed by high winds in the upper atmosphere, but when things settled down, they did the launch.

And the launch itself seemed to go perfectly. The Falcon leaped off the launch pad, blasted off into space with its twin reused rocket boosters firing. After a couple of minutes, the boosters detached and returned to Earth, followed by the central stage.

We watched the twin boosters return to Cape Canaveral and land almost simultaneously. The fate of the central third core is still unknown, the video feed cut off as the rocket was returning to the autonomous drone ship in the Atlantic. This happens from time to time, apparently, as the blast of the rocket’s landing engines can throw the drone’s communications antennae out of alignment.

The payload fairing detached and fell away, revealing the Tesla to the Universe, and the second stage continued on, carrying the car to orbit. As David Bowie’s “Space Oddity” began its endless looping background music, we could see the car floating free above the Earth.

According to Musk, the car’s going to spend the next 5 hours or so enjoying the radiation of the Van Allen Belts before its final burn to carry it out onto a Marslike orbit.

In completing this launch, SpaceX demonstrated several things. The Falcon Heavy is a reality. If you’ve got $90 million burning a hole in your pocket, and you want to send 54 tonnes of cargo into low Earth orbit, they’ll be glad to take your order.

They tested using previously flown Falcon-9 first stages as components in the Falcon Heavy. They tested landing three boosters simultaneously.

They also got a chance to test out their new spacesuit in actual space. And I guess, they’ll know if Tesla Roadsters are ready for the harsh environment of interplanetary space.

I’m not sure how long this’ll last, but you can watch a live view from over the shoulder of StarMan as he sits behind the wheel, with the reassuring “Don’t Panic” sign on the Roadster’s dashboard.

Interesting side note, Musk announced that they wouldn’t be making the Falcon Heavy human rated, they’ll be saving that trick for the BFR which should start launching in the next few years, or decades, or however long things take. In other words, we’ll need to go through this whole process all over again of anticipation, and excitement.

Clearly this story is still unfolding. Will the car make its transfer burn? Did the third booster land? Does anyone want to buy 54 tonnes of cargo launched to orbit for $90 million? Will the BFR ever launch? Will Jeff Bezos and Blue Origin catch up?

Stay tuned.

Why Finding Alien Life Would Be Bad. The Great Filter

The Great Filter by Kurzgesagt
The Great Filter by Kurzgesagt

Since the Universe is big and old, and life on Earth didn’t take relatively long to evolve, then life should be everywhere in the Universe. And yet, no matter how hard we look, we don’t see any evidence of it out there, not on Mars, not sending us radio messages, and not taking over entire galaxies and using up all their energy.

This, of course, is the Fermi Paradox, and it’s an absolutely fascinating concept to think about. There are many possible resolutions to the Fermi Paradox, but most of them are unsatisfying. Sure, we could be living in a cosmic zoo, or we fundamentally misunderstand how difficult it’ll be to travel to another star.

And maybe we’re just the first lifeforms in the observable Universe that have reached the level of technology that can conceive of exploring the Universe. But then, what are the chances of that? That really seems unlikely.

But then there’s the idea of the Great Filter. That there’s some kind of event that affects every single intelligent civilization, stopping it from reaching out into the galaxy, sending out signals, and exploring other worlds. Something wipes them out every time.

A scene from the episode

And considering the fact that we’re on the verge of becoming a multi-planet species ourselves, this concept of the Great Filter becomes even more unsettling.

It could be right around the corner from us.

Our friends at Kurzgesagt just released a video all about the Great Filter, and honestly, I think it’s the best video they’ve ever done. The animation, as always, is excellent, but the way they approach the Great Filter is really innovative, showing how evidence of life in the Universe is actually a bad sign, since it means we’re probably not the first life forms out there.

Which means the Great Filter is even more likely.
