Starship Flight Test
It’s amazing we get to watch these on livestreams. SpaceX willing to expose its R&D process and high-risk work to the world in real-time. The world definitely needs more companies taking big risks and pushing forward.

Beautiful and inspiring stuff from SpaceX:
A convincing case for Elon to put his focus all-in on SpaceX, and not 6 other ventures at once.
Byrne Hobart makes the case for Starlink’s business model:
The line between a vision and a sales pitch is always blurry, and Elon Musk is unusually good at using this to his advantage. There’s a reasonable case that Starlink is just a natural way to amortize the fixed cost of SpaceX’s investment in launch infrastructure. But a sufficiently compelling sales pitch has a way of coming true, and if part of the pitch of Starlink is that it’s a censorship-resistant communications medium that creates access to the global Internet, not individual countries’ more...
SpaceX’s Starlink constellation is getting pretty dense. So far they’ve put over 1,000 in orbit, with a goal of eventually reaching tens of thousands.
Someone put together this map visualization showing the orbit position of each bird, animated.
The resemblance between Martian and Terran topography is amazing. Mars has volcanism, plains, valleys, and hard evidence of water formerly everywhere.
Great shots here with renderings of Martian topography.
Bryan put together this neat little utility for merging point data with containing polygon attributes with spatial join queries. It uses Turf.js to do the geoprocess in the browser.
Amazing photography of the Mars surface:
NASA’s Curiosity rover has captured its highest-resolution panorama yet of the Martian surface. Composed of more than 1,000 images taken during the 2019 Thanksgiving holiday and carefully assembled over the ensuing months, the composite contains 1.8 billion pixels of Martian landscape. The rover’s...
This is a physics simulator that replicates the physics of interstellar objects. You can simulate massive planetary collisions or supernovae in the Earth’s solar system, in case you want to see what would happen.
A neat catalog “map” of mathematics, with visualizations of things like prime numbers, symmetry, calculus, and more. Quanta Magazine does fantastic work.

This is a neat clip from Walt Disney’s Disneyland TV series. Wernher von Braun explains the future technology that’ll take us to the Moon, in 1955, several years before the Mercury program even began.
Bloomberg has been publishing this video series on future technologies called “Giant Leap.” It’s well-done and a nice use of YouTube as a medium.
This one explores a number of new companies doing R&D in microgravity manufacturing — from biological organ “printing” to creation of high-quality fiber optic materials. There are still some challenges ahead to unlock growth of space as a manufacturing environment, but it feels like we’re on the cusp of a new platform for industrial growth in the near future.
...This is an absolutely phenomenal project showcasing each of the major satellites in the Solar System. The full interactive maps of each one are incredible. It shows how much data we’ve gathered about all of these bodies with imagery on each one and thoroughly mapped with place and feature names.
A cool piece of news here. We bought our house with Redfin and had a great experience with it, after using the website heavily during the house search...
NASA has developed a portable atomic clock that would allow deep space probes to navigate on their own. As Geoff Manaugh notes here, when you’re traveling in space with no access to a frame of reference, travel time from a point of origin is how one orients:
One might say that the ship is navigating time as much as it is traveling through space—steering through the time between things rather than simply following the lines that connect one celestial object to another.
The general problem of ship orientation and navigation...
We took the kids over to Kennedy Space Center on Saturday on the way up to Jacksonville. A quick stopover in Titusville Friday night then morning over at the Cape.
I always loved visiting KSC when I was younger. We had the opportunity to go and see multiple launches over the years, including a couple of Space Shuttle launches. Visiting again brought back memories since they’ve got several things there that haven’t changed much over the years. On the way in you get to walk through the Rocket Garden, which...
This is a neat interactive tool to visualize distortion due to map projection using Tissot’s indicatrix, a mathematical model for calculating the amount of warp at different points:
Nicolas Auguste Tissot published his classic analysis on the distortion on maps in 1859 and 1881. The basic idea is that the intersection of any two lines on the Earth is represented on the flat map with an intersection at the same or a different angle. He proved that at almost every point on the Earth, there’s a right angle intersection...
This is an old announcement, but new to me. CloudFlare now hosts privacy-centric DNS at 1.1.1.1, available to all:
We talked to the APNIC team about how we wanted to create a privacy-first, extremely fast DNS system. They thought it was a laudable goal. We offered Cloudflare’s network to receive and study the garbage traffic in exchange for being able to offer a DNS resolver on the memorable IPs. And, with that, 1.1.1.1 was born.
