Video of the March 2014 Senate Defense Subcommittee hearing on National Security Space Launch programs. Elon Musk of SpaceX testifies alongside ULA's CEO, a GAO official and a policy expert, on launch contracts and Russian engines.

Bruce Waggoner of the Voyager team describes how engineers diagnosed Voyager 1's 2023 loss of telemetry and patched its flight software from 15 billion miles away. The talk covers the spacecraft's architecture and the scarcity of old documentation.

Eager Space examines the practicality of putting data centers in orbit, walking through three scenarios with cost calculations and the launch cost reductions that would be required.

Fraser Cain interviews JPL physicist Slava Turyshev about using the Sun's gravity as a lens to image distant exoplanets. They cover how the lens works, how a spacecraft would align with it, and mission design.

A 1966 NASA safety film teaching workers how to handle toxic rocket propellants such as hydrazine and nitrogen tetroxide. It explains the hazards of these corrosive, flammable and toxic chemicals and what to do after contamination.

JPL's David Cummings presents at the 2025 Flight Software Workshop how the team diagnosed and fixed the 2023 Voyager 1 anomaly from billions of miles away. It walks through the flight computer and the memory fix.

Part two of EEVblog's visit to the NASA/CSIRO Canberra Deep Space Communication Complex, showing the control room and how operators contact Voyager 2. It includes live data and spectrum displays.

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.

Trailer for the documentary It's Quieter in the Twilight, shown at the Boston SciFi Film Festival. The film follows the engineers who keep the Voyager spacecraft running.

A four-pane view of Armadillo Aerospace's Mod vehicle on a June 2010 boosted hop. The flight includes engine shutdown, drogue chute deployment, an engine restart and a safe landing.

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.

Dave Jones of EEVblog and Richard Stephenson tour the 70m DSS43 dish at the Canberra Deep Space Communication Complex and explain how NASA talks to Voyager 2. It covers the transmitters, receivers and tracking involved.

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.

Stuart Armstrong of the Future of Humanity Institute gives an Oxford physics talk on what exploratory engineering suggests about the Fermi paradox. He argues that von Neumann probes and Dyson spheres are plausibly buildable and asks what traces advanced civilizations would leave.

Ron Garret tells the story of the Remote Agent Experiment on NASA's Deep Space 1, where autonomous software controlled a spacecraft in 1999. He describes debugging Lisp code remotely from millions of miles away.

A clip of Sandy Munro, a veteran automotive engineer, describing his visit to a SpaceX Starship design review and meeting Elon Musk. He says he was struck by how deeply Musk is involved in engineering.

An animated Gabbard diagram of objects in low Earth orbit from 1959 to 2021, showing altitude over time. It highlights major debris-generating events and how low-altitude debris decays out of orbit.

React Helsinki meetup recording featuring a talk on lessons with Apollo GraphQL and Linear co-founder Tuomas Artman on real-time sync for web apps. The sync talk explains Linear's local-first architecture.
