In her final days as ISS commander, Sunita Williams gives an extensive tour of the station's modules and research facilities, narrating the work done aboard.

Explains the proposed NASA JPL plan to use the Sun as a gravitational lens, sending solar sail craft to its focal region to image an exoplanet's surface. It covers the distances involved, how imaging with the Sun would work and the mission design.

Veritasium's Derek Muller visits NASA JPL to see the Mars helicopter Ingenuity before it was mounted on the rover. He explains how it can fly in Mars's thin atmosphere with large, fast-spinning contra-rotating rotors and low mass, and covers power and cold.

Astronaut Mike Mullane explains normalisation of deviance, where teams gradually come to accept violations of their own safety standards. He uses the Challenger shuttle disaster as the main case, drawing on NASA's ignored warnings before the launch. It is the first part of a talk given to a fire-fighters' association.

NASA's animated explanation of the Curiosity rover's Mars landing, which relied on a complex automated sequence taking about seven minutes. It features NASA engineers discussing the risks before the 2012 landing.

A short, music-driven video built from Neil deGrasse Tyson's remarks on why advancing the space frontier matters, contrasting NASA's small budget with war spending and stressing inspiration.

A short unofficial NASA-style spot from Reid Gower's Sagan Series, setting Carl Sagan's words about humanity spreading through the Solar System to visuals and music.

A documentary following Robert Zubrin and the Mars Society as they push the Mars Direct plan for sending humans to Mars using current technology and local resources. It also covers the clash with NASA's more expensive approach.

Music video for Public Service Broadcasting's "Go!" from the album The Race For Space, built from NASA audio and archival material of Apollo-era voices.

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.

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 1968 NASA film from the US National Archives explaining why the US needed a nuclear rocket and how the engine works. It also shows combined nuclear and chemical stages for a manned Mars mission.

A June 1986 CNN interview with physicist Richard Feynman about the Challenger disaster and the management failures he found while serving on the investigating commission.

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.

Short Curious Droid video on why NASA could not simply rebuild the Saturn V's Rocketdyne F-1 engine for the SLS boosters. It explains that the engines were hand-tailored and that much of the know-how was never documented, so the blueprints were not enough.

Short footage from a NASA space suit test in which a technician is exposed to near-vacuum after an accidental depressurization. It shows the instantaneous effects on a human body.

A NASA video on the 29 days after the James Webb Space Telescope's launch, when thousands of parts must deploy in sequence on the way to its destination a million miles away.

NASASpaceflight's 24/7 live stream from SpaceX's Starbase in Boca Chica, Texas, showing Starship and Super Heavy development, testing and launches.

Footage from a camera on a Space Shuttle solid rocket booster from liftoff through descent, with audio enhanced by Skywalker Sound from the original camera microphones. The sound is real, not foley.

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.
