Real Engineering explains why SpaceX is building Starlink, including the economics of satellite internet. It covers the latency advantage of light in vacuum over fiber for long-distance links.

Mark Handley of UCL looks at how SpaceX's November 2018 revisions to the Starlink constellation affect network behavior. The video visualizes the orbits and routing and estimates latencies, building on his earlier video and research paper.

Mark Handley of UCL explains, with simulation visualizations, how early Starlink satellites without inter-satellite links could still give low-latency wide-area communication by hopping via ground relays. He shows it can beat fibre on many long paths.

A 43-minute skeptical critique arguing that Starlink fails to live up to its promises, covering satellite lifespan, costs, bandwidth and viability. The creator later added an update about FCC grant requirements.

Thunderf00t critiques Starlink's economics and technical claims alongside other unfulfilled Musk promises. It argues Starlink is a poor business.

A 105-minute technical deep dive from Noise In Space evaluating whether Starlink satellites could work as synthetic aperture radar. It covers SAR signal-to-noise, amplifiers, antennas, duplexing, phased array beamforming and simulations of V2 Mini and V3 satellites.

Branch Education explains how Starlink works, from the ground dish and satellites to phased-array beam steering and data routing. Animations cover how a beam stays connected to a satellite moving at 27,000 km/h.

The Signal Path takes apart a Starlink dish layer by layer, analyzing the phased array RF design, system architecture and integrated circuits, with an X-ray of the RF stack.

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.

Elon Musk joins the All-In Summit 2023 by Starlink for an interview on Ukraine and Starlink, X, the creator economy, China, AI and self-driving.

Full recording of Elon Musk's January 2015 presentation and Q&A at the SpaceX Seattle office announcement. He lays out plans for a satellite constellation to provide low-latency global internet, tied to funding Mars ambitions. Pauses between questions have been edited out.

Scott Manley explains the thermal balance of spacecraft and how a satellite could be configured to radiate away the heat from datacenter-scale computing in space. His rough numbers suggest it is feasible.
