Recently, Neil deGrasse Tyson visited Stephen Colbert to talk about aliens and his new book Take Me To Your Leader: Perspectives On Your First Alien Encounter. He discussed aliens, why you probably shouldn’t shake hands, and how they might mirror what they see of humanity. 

It made me think of the story I wrote on that topic, and how I hope that humanity does more good than not. I’ve re-posted before but I like the story, so here it is again. Click through for the full piece.

We Are Mirrors | J.R. Johnson

You and Yours

I came from the stars to meet you. I was happy. Excited, even. First contact with your verdant world. Think of all that we could share with you.

“You” could have meant a lot of things. I started with one of the most populous. An insect.

I remember little of what it was like, a flash of light, a warm wriggle in a puddle after rain. The feel of wind in my wings.

It’s embarrassing to say this now, but I was promptly eaten.

Here’s an interesting interview with astronaut and naval aviator Victor Glover, pilot for Artemis II’s Orion spacecraft.

And when those parachutes came out, when the mains came out, it was like God himself led us down to the water. And I had a big old grin on my face. It was intense. It went from intense to pure elation.

If you are curious about what it’s like to pilot in space, the difference between a touchscreen controller and stick-and-throttle hand controllers, or the “very intense” 13 minutes and 36 seconds of reentry, read on.

I was!

NASA reminded me that we have a new, if transitory, neighbor in the skies overhead. The comet PanSTARRS is making a quick visit and tonight is the closest it will come to the sun.

APOD- 2026 April 18 – PanSTARRS and Planets

This is a good weekend for northern hemisphere comet watchers to try to catch PanSTARRS an hour or so before sunrise, as the comet grows brighter approaching its perihelion on April 19. On April 26 the comet makes its closest approach to our fair planet but by then will be difficult to see in the solar glare. Good views of this comet PanSTARRS in late April and early May will be from the southern hemisphere.

If your skies are clear and dark, check it out!

Today is the day, folks, when our friendly neighborhood astronauts make their (hopefully trouble-free) return to our home planet. 

As we wait for splashdown, anticipated to be just after 8pm EDT tonight, here is an interactive look at What’s Inside NASA’s Mission Control.

And to save you from tracking down one of the many (many) space-themed Artemis links I’ve put up over the past couple of days, you can watch tonight’s homecoming here starting at 6:30pm EDT!

Am I still on the Artemis II space train? I am, because the story is optimistic and nerdy and cool. 

You may have heard that the astronauts are getting wake-up songs from Mission Control. If you’ve wondered what those songs are, here you go!

All the Wake-up Songs Astronauts on Artemis II Have Heard So Far

Each morning, the flight crew is awoken by a song, hand-picked by Mission Control specialists back home on Earth. The long-standing practice keeps astronauts on schedule and connects them to the rest of humanity.

Here are the songs in YouTube playlist form: All Artemis II songs

The crew is scheduled to splash down tomorrow evening (April 10th), off the coast of San Diego. Stay tuned for that, and for the final entry in their wake-up playlist!

Since my recent posts have spent a lot of time in space, let’s take a slight break from the nonfiction drama of NASA’s Artemis II mission and shift over to the fictional world of space adventure.

In his books, Andy Weir (The Martian) works hard to bring scientific accuracy to his fiction. The challenge is balancing the demands of a thrilling story with the science that grounds it in reality.

How did he do? Experts weigh in.

How plausible is ‘Project Hail Mary’? Experts have thoughts

While “Project Hail Mary” has its share of explosions and catastrophes, it’s the thinking that’s thrilling. Grace and Rocky must come together, with tools and whiteboards, craft and ingenuity, to solve a seemingly insoluble problem. They make mistakes, but they learn from those mistakes and from each other.

And an astrophysicist also has thoughts:

Project Hail Mary is packed with hard science. An astrophysicist breaks it down

… when I walked out of a recent preview screening of the film adaptation of Andy Weir’s 2021 science fiction novel Project Hail Mary, I had tears of joy in my eyes. The filmmakers had done justice not just to the original story, but also to the science at the heart of it.

From NASA, with lots of interesting subsidiary links: 

The Science Behind ‘Project Hail Mary’ – NASA Science

Let NASA shed some light: Explore the resources below to learn the science facts fueling the science fiction.

(Wait, Tau Ceti was also featured in fiction by Isaac Asimov, Arthur C. Clarke, Frank Herbert, Robert Heinlein, Ursula K. Le Guin, and Kim Stanley Robinson? And was the setting for Barbarella? This planet gets around!)

The final assessment of the science? Not perfect, but good. And precisely accurate or not, this promises to be another very entertaining movie. (I’ve read the book but haven’t seen the film yet. Yes, I am a little behind the curve!)

Since we’re here, how about an article on the movie as a climate parable? (warning, spoilers!)

AMAZE AMAZE AMAZE! Yes, this is an article about Project Hail Mary as climate parable

And what the heck, here’s the movie trailer just for fun.

A quick update from the solar system’s coolest road trip: the Artemis II mission just set a new distance record, going farther into space than the Apollo 13 astronauts did in 1970.  

Artemis II astronauts share their first images from the historic mission | CNN

“There was a moment about an hour ago where Mission Control Houston reoriented our spacecraft as the sun was setting behind the Earth. And I don’t know what we all expected to see at that moment, but you could see the entire globe, from pole to pole. You could see Africa, Europe, and if you looked really close, you could see the northern lights. It was the most spectacular moment, and it paused all four of us in our tracks.” — mission commander Reid Wiseman

Check out NASA’s Artemis II image repository on Flickr for more shots from space.

What else are our friendly neighborhood explorers up to? Oh, you know, today they’re just doing a quick flyby of the Moon! 

How cool is that?

The Artemis II Orion spacecraft has launched, and the mission is underway!

There is also a livestream from Orion itself (claustrophobes need not apply), but availability is spotty due to bandwidth and popularity. Because space!

NASA’s Artemis II mission is (as of right now!) still a go. Here’s a site with a countdown to launch and a tracker for when it happens.

And here’s a video on the mission in case you didn’t get enough background material yesterday.

And here are a couple of Artemis-themed games to play, just for fun: Artemis Game Hub

Just over six hours now if all goes well. Fingers crossed!
