Hello, everyone, and thank you for reading!
This is a short (~8 minute) video I made to introduce the story Bringer of Light.
I’ll be posting a couple more videos in the near future about the characters, location, and science behind the story.
Check it out, and share freely!

The moment we’ve all been waiting for is nearly here!
Bringer of Light is finally set to be released on March 15, 2024! (Click the link to see a book synopsis and two brief excerpts; Smashwords also has an excerpt from the beginning chapters.)
Stop by Draft2Digital to see links to your favorite bookstore online!
UPDATE: I have some difficulty convincing D2D to distribute to Amazon. Therefore, I have decided to publish Bringer of Light directly on Amazon. Stop by here to order for Kindle (released March 15th). Paperback and hard cover are also in the works.

Aiming the laser at the spacecraft so the transceiver knows where to point back is the most difficult part, Wright said. And because Earth and the spacecraft are both moving, the lasers must point to where the destination will be in a few minutes.
https://www.washingtonpost.com/technology/2023/12/19/nasa-laser-video-streaming-space-mars-cat/
“The beam’s so narrow, it can’t just point to Earth. It needs to know exactly where on Earth,” Wright said. “Trying to hit a dime from a mile away while you’re moving at 17,000 miles an hour — that’s the challenge.”
So NASA has been working on this idea for a while now. The invisible laser beam that carried this video file came from the Psyche probe, on its way to the asteroid belt between Mars and Jupiter.
Psyche is 19 million miles away right now. The laser beam took 108 seconds to reach Earth.
Mars and Earth are on average 140 million miles apart and can be up to 250 million miles apart depending on the timing of their respective orbits.
I don’t think lasers are the answer here. A good start, maybe, but you can do the math. Having to wait between 10 to 20 minutes, or more, for a one-way transmission (double that for an exchange of messages) would not be ideal for a human settlement in an emergency.
Star Trek style instant interstellar communication is still just scifi. Unless there’s still something out there we haven’t found yet, even quantum communication will take time…
But at least NASA has finally realized that non-science people like cat videos.

Carbon accounted for almost five percent of the sample’s total weight, and was present in both organic and mineral form, while the water was locked inside the crystal structure of clay minerals, he said.
Scientists believe the reason Earth has oceans, lakes and rivers is because it was hit with water-carrying asteroids 4 to 4.5 billion years ago, making it a habitable planet.
https://www.sciencealert.com/first-look-at-pristine-asteroid-dust-reveals-abundance-of-water-and-carbon
We have ample evidence now that all water on Earth was brought during the “Late Heavy Bombardment” period (4~4.5 billion years ago). Imagine how many rocks it took to get enough water (estimates anywhere between 20 and 200 million years of asteroid after asteroid slamming into the Earth).
And the only reason life exists on Earth is that there is enough iron and nickel in the Earth’s core to generate a magnetic field to prevent solar radiation from ripping off the atmosphere. Which is likely what happened to Mars.
(Alright, alright, technically electrical currents running through the liquid iron outer core as well as in the crust and ionosphere also contribute to the magnetic field. Go check out this horribly complicated explanation if you like.)
Note that this is the third time to get asteroid dust to examine. JAXA has managed to do this twice now. But Hayabusa-2 only got about 5 grams. The OSIRIS-REx project got about 250 grams (1/2 lb). Lots more = lots more to save for future researchers who will have developed even more sophisticated analysis methods.
Now lets get some PEOPLE on those things and start mining and living in space, already!

Currently, OSIRIS-REx is located at a distance of 7 million km from our planet. On September 24, OSIRIS-REx will drop a capsule with samples of asteroid matter, after which it will enter the earth’s atmosphere and land on the territory of the Utah Test and Training Range.
https://universemagazine.com/en/osiris-rex-is-on-a-course-for-earth/
The tiny spacecraft launched back in 2016 and reached the asteroid Bennu in 2021.
One main reason for this mission is to find out what Bennu is made of. After the asteroid spewed out tiny “micromoons,” OSIRIS-REx successfully collected a tiny soil sample. By “tiny,” I mean less than 50 to 60 grams. And it couldn’t actually land, since the asteroid is too small to have enough gravity to support the spacecraft.
Now we have less than two weeks to find out what’s in the soil — assuming the capsule is retrieved without incident. And then OSIRIS-REx will head back out to visit yet another asteroid (Apophis) in 2029.
Yes, that famous “planet-killer” the media screamed about a few years ago as “the most dangerous asteroid in the world.” (uh. “in the world”?) It will “only” approach within 38,000 km in April 2029, but could possibly collide in 2036.
No problem.

Way back in 2015, my good friend Rami Z Cohen came to me with an idea for a story. He had written two or three scenes about a group of asteroid hunters who stumbled upon something bizarre. The idea of mining asteroids was news at the time (and still is, although probably too expensive right now and not a worthwhile investment until we actually get some people in space who need metals without relying on NASA/ESA/JAXA/ISRO/etc).
I was more interested in philosophical aspects of finding that we are all (as the late great Carl Sagan loved to put it) “star stuff” (he meant carbon being created by supernovas, but we also know that asteroids are the way we got amino acids to rain down on ancient Earth).
So Rami and I began to email ideas back and forth for a few weeks, then we started to flesh out his characters and plot. I wrote a synopsis and outline and we hashed out the background.

Of all the asteroids they modeled, the one with the largest risk of impact was a kilometer-wide asteroid known as 1994 PC1. Over the next thousand years, the probability that 1994 PC1 will cross within the orbit of the Moon is a paltry 0.00151%, hardly worth worrying about.

Thanks to Glen Hill over at Engagin’ Science (formerly Scientia, which apparently was far too Latin- and science-esque for search engines to handle) for bringing this (not-so Earth-shattering) info to my attention.
Sorry, folks. Hollywood was once again wrong (sigh).

The agency earlier said the object was expected to “safely strike” the earth’s atmosphere near to the French city of Rouen.
https://www.bbc.com/news/uk-64621721
“Near to”? OK.
Anyway, “SAR2667” provided some cross-cultural entertainment for people living in England, France, Belgium, and the Netherlands. Lots of photos and videos online.
Interesting note from ESA: they were able to detect it and notify everyone exactly where and when it would disintegrate.
Since there are more than 30,000 of these things that orbit the Sun relatively close to Earth’s orbit, it’s a good thing we’re getting better at detecting them. Maybe we’d better up the ante on deflecting them…

An asteroid is on its way to Earth, but don’t worry – the end is here Not here. The asteroid, named 2023 BU, is about the size of a van and is expected to miss our planet during Thursday’s flyby. However, according to a NASA scientist, it will be “one of the closest approaches of a known near-Earth object ever recorded.”
https://newsbeezer.com/germanyeng/a-truck-sized-asteroid-will-come-extraordinarily-close-to-earth-tomorrow/
This thing is coming closer than even some satellites, but it’s still small enough for most of it to burn up in the atmosphere.
Most of it.
Yikes.

Since the Hayabusa2 returned with the sample from the Ryugu asteroid in December 2020, several important discoveries have been made – most notably analyzes confirming the presence of substances thought to be the building blocks of life on the asteroid, such as liquid water and organics fabrics.
https://newsbeezer.com/germanyeng/ryugu-asteroid-helps-unravel-the-origin-of-life-on-earth/
Hayabusa-2 took several years to land on Ryugu (literally “Dragon Palace”), pound out just over 5 grams of asteroid material, and bring it back to Earth (landing in Australia in late 2020).
NASA scientists have confirmed not just frozen water but liquid — inside crystals called pyrrhotites. JAXA scientists (pictured above with Prof Tsuchiyama of Ritsumeikan University, my main employer!) continue to check the density of the samples.
The water is similar to the carbon dioxide-laden water of hot springs. The research teams have already discovered over 20 amino acids, the basic protein building blocks of carbon-based life.
Another theory called “panspermia” proposes that a key mineral (boron) missing on early Earth came in an asteroid from Mars. ☄️ Hmm. Did Mars produce asteroids? Or more like asteroids hit Mars and broke off lots of tiny fragments? That somehow survived the journey to Earth?
Seems a little unlikely. But there is now evidence that at least some proteins came from space rocks.
So, sorry, Ridley. This isn’t how it happened. Cool movie, though.
