Barnes & Noble's Lifeline

Elliot bought Waterstones last year, and it's already seen a solid turnaround. The fund plans to name the Waterstones CEO as CEO of BN as well.

Who knows? Maybe BN will go back to actually being a bookstore. Crazy idea, I realize. 😏

Mars 2020 Rover Has A Date With Jezero Crater

This is where the Mars 2020 Rover is heading. From this picture, I think you can guess why.

Jezero Crater is an ancient lake that formed inside an impact crater. Detailed study of the features of the lake led scientists to conclude that the lake is ancient and did not experience times when water went down. Due to its long lifespan as a lake, it’s possible that life may have developed in the lake. It’s possible, though not necessarily likely, that preserved signs of life are waiting to be discovered at Jezero Crater.

The Sky In X-Ray

NASA is building up a map of the entire sky seen in X-rays, line by line with its NICER experiment.

In this image, numerous sweeping arcs seem to congregate at various bright regions. You may wonder: What is being shown? Air traffic routes? Information moving around the global internet? Magnetic fields looping across active areas on the Sun?

In fact, this is a map of the entire sky in X-rays recorded by NASA's Neutron star Interior Composition Explorer (NICER), a payload on the International Space Station.

Is Our Universe Too Vast For Even the Most Imaginative Sci-Fi?

Thoughts? Agree, or disagree?

Of course even wild science fiction tends to be (though not always) distinctly human in character. No matter how far into the universe we one day reach, we'll still see it from a human perspective. Also, getting outside a "human" head and imagining the viewpoint of a truly *alien* alien is no easy feat. Hopefully I've accomplished it once or twice.😌

It's also true that the vast, mind-boggling distances involved are humbling. Even the 40 galaxies of the Anaden Empire, even the 16 million light-years distance to the Asterions' Gennisi Galaxy, are just a teeny tiny neighborhood of the universe. I keep going bigger, but the universe continues to stretch for what feels like infinity.

Ice On Mars

New layers of water ice have been found beneath Mars' North Pole . These layers were found to be 90% water in some places, and are believed to be the remnants of ancient polar ice sheets. If melted, the researchers indicate that they would create a global ocean with a depth of at least 1.5 meters.

The Next Space Race

In 2019, on the brink of the 50th anniversary of Apollo 11, the competition that will rocket humanity into the cosmos is between two passionate and brilliant multi-billionaires: Jeff Bezos and Elon Musk.

This blog outlines each of their capabilities, as well as their near-term and long-term vision for the final frontier: https://singularityhub.com/2019/05/24/the-next-space-race-bezos-vs-musk/.

The article includes a lot of insights into the personalities at play, their origins, and the details of their respective visions.

Boulders on Bennu

An abundance of boulders litters the surface of asteroid 101955 Bennu in this dramatic close-up from the OSIRIS-REx spacecraft. Taken on March 28 from a distance of just 3.4 kilometers (2.1 miles) the field of view is about 50 meters across while the light colored boulder at top right is 4.8 meters tall. https://apod.nasa.gov/apod/ap190524.html

Incredible to think about, isn’t it?

Tricky Thing, Measuring the Universe

From science writer Corey Powell: “Something looks seriously wrong with our measurements of the universe. My editor challenged me to write the story so that it would make sense to any curious reader. Here's my take.” https://www.nbcnews.com/mach/science/universe-may-be-billion-years-younger-we-thought-scientists-are-ncna1005541

I have thoughts on this, but there’s a decent chance I’ll write them into a story, so I should probably keep them to myself ;).

Neutrino Beams & Black Holes

Well OF COURSE advanced civilizations could be using hyper-dense objects like neutron stars as focusing tools to send communications streaming across space on neutrino beams.

I love the quote from Freeman Dyson: “if the physics allows it, it is possibly technologically feasible.” Indeed. G. S. Jennsen's Corollary: "Just because we can't do it today doesn't mean we can't do it tomorrow." And someone else could be doing it now....

Heaven Is A Place On Earth

…and it’s called the Tattered Cover Bookstore

By sheer coincidence, Patricia Briggs was giving a talk and reading while we were there. About 60 people were crammed into the lower-level meeting space. #MrJennsen whispered sweet nothings in my ear about how that would be me at the podium one day 😉; I pshaw'ed him, went upstairs and bought some sci-fi books with beautiful covers.⠀

A Vision Of Our Future

Lots of big news out of Blue Origin! Jeff Bezos gave an inspirational and aspirational speech in which he laid out a far-reaching vision for getting humans, manufacturing and resource development out into the solar system. That starts with the moon, and he unveiled a new lunar lander module, secretly in development for the last 3 years, which he causally offered to NASA for use in their 2024 lunar landing plans.

Here’s an overview of the event: https://arstechnica.com/science/2019/05/jeff-bezos-unveils-his-sweeping-vision-for-humanitys-future-in-space/, or you can watch the entire presentation here (it’s worth it if you have the time): https://www.youtube.com/watch?v=GQ98hGUe6FM.
