A short visualization from HotNets researchers of routing and latency over SpaceX's proposed Starlink constellation, based on its FCC filings. It shows orbital shells, link topology and how inter-satellite routes could beat terrestrial fiber on long distances.

EEVblog interviews Richard Stephenson of NASA's Canberra Deep Space Communications Complex about how the 70m DSS-43 dish is used to contact Voyager 2. It covers the ground antenna and low-noise receiver side of deep space communication. This is a 2023 re-release of a 2017 video.

A JuliaCon talk by a NASA Launch Services Program engineer on modeling spacecraft separation dynamics in Julia. He describes replacing a Simulink-based workflow for checking launch vehicle separation requirements with Julia and ModelingToolkit, with large speedups and much shorter code.

PBS Space Time explains the quantum eraser experiment, in which erasing which-path information appears to reverse causality in a double-slit setup. It discusses what this means for quantum mechanics.

PBS Space Time explains the Higgs field and how the Higgs mechanism gives particles mass within quantum field theory. It is a ten-minute overview for a lay audience.

Scott Manley looks at SpinLaunch, which aims to throw launch vehicles out of a spinning launcher at hypersonic speed. He covers its recent Mach 1 test of a one-third scale launcher and the engineering problems that remain.

Scott Manley analyzes the idea of putting data centers in orbit, prompted by Lumen Orbit's funding. He examines the claimed advantage of constant solar power against launch cost, cooling and mass.

A tour of Christian Schallert's 24 square meter apartment in Barcelona, designed so that it looks like an empty cube until he builds the furniture he needs. Kirsten Dirksen shows how the space is transformed for cooking, sleeping and dressing.

A PBS Space Time episode explaining how space and time swap roles inside a black hole's event horizon. It is part of the channel's black hole series.

Breaking Taps explains how the cryogenic mirror actuators on the James Webb Space Telescope achieve nanometer precision using flexures. It shows a 3D-printed replica and how one motor handles both coarse and fine motion.

Helmet-camera footage of linemen installing a spacer on an energized 765,000 volt transmission line, working from a helicopter. The crew bonds on and off the live wire as part of the job.

A PBS Space Time episode introducing de Broglie-Bohm pilot wave theory, an interpretation of quantum mechanics that avoids much of the strangeness of the mainstream views. It is aimed at curious lay viewers.

PBS Space Time explains the Bohr-Einstein debate over quantum mechanics and how quantum entanglement settled it. It covers the weirdness of measurement and nonlocal correlations.

A PBS Space Time episode asking what matter, mass, and energy really are, starting with inertial versus gravitational mass and what mass-energy equivalence means.

PBS Space Time introduces Miguel Alcubierre's warp drive, explaining how spacetime itself could be warped rather than moving a ship through it, and whether it is physically possible.

PBS Space Time explains what happens as you approach and cross a black hole's event horizon, using Penrose diagrams and light cones as the tool for understanding spacetime there.

A review of the Symbolics Space Cadet keyboard, with its Honeywell Hall effect switches, including how it sounds and feels, and a typing demonstration. It is part of a series of vintage keyboard reviews.

Bret Victor's talk proposing a new kind of maker space built for seeing and understanding a project's behavior: inside it, across time and across possibilities. It argues for scientific understanding over recipes and rules of thumb.

A recapture in 50fps HD of Spaceballs' 'State of the Art', an Amiga demo released at The Party 1992. It showcases the Amiga's real-time animation, graphics and music in a few minutes.

Kevin Spacey, giving the MacTaggart Lecture at the Edinburgh Television Festival, urges TV channels to give viewers control. He points to Netflix's House of Cards release as evidence that audiences want to watch on their own terms.
