Short footage of the 1983 Soyuz T-10-1 pad fire, in which the launch escape tower pulled the crew away seconds before the rocket exploded.

Course outline for Stanford's online GNSS course, introducing how GPS works and the many uses of satellite navigation. The series pairs short lectures with backyard experiments using smartphones.

Sped-up onboard camera footage of the Falcon 9 first stage landing on a drone ship during the THAICOM 8 mission on May 27, 2016. It shows the descent from grid fin deployment to touchdown.

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.

SpaceX's recap of the Falcon Heavy debut launch, with side booster landings and a Tesla Roadster with Starman sent into orbit.

A NASA Langley concept video for HAVOC, a lighter-than-air vehicle that would carry two astronauts on a 30-day mission in Venus's upper atmosphere. It explains why the planet's surface is so hostile and why the clouds are more habitable.

SpaceX footage of the Grasshopper vehicle's 744 m test hop, filmed from a hexacopter that gets closer than earlier flights. Grasshopper was a vertical takeoff and landing rig built to test returning rockets to the pad.

A three-minute minutephysics video on the orbital mechanics of why crashing into the Sun takes far more energy than leaving the solar system.

A two-minute clip recorded on a Kennedy Space Center tour showing a Space Shuttle thermal tile that can be held by hand while its surface is extremely hot. It demonstrates the tile's remarkable insulating properties.

A NASA and Durham University supercomputer simulation suggesting the Moon may have formed within hours of a giant impact between Earth and a Mars-sized body. It is one of the highest-resolution giant-impact simulations run.

A SpaceX concept animation showing the planned fully reusable Falcon 9, with both first and second stages performing vertical landings.

A short SpaceX video of the Dragon 2 pad abort test, in which the capsule's thrusters fire to carry it away from the launch pad. It also shows the pad deluge system.

Footage of the failed Mercury-Redstone 1 launch, where the engine cut off almost immediately after liftoff. The escape tower and parachutes then deployed because the rocket thought the flight was over.

A two-minute clip of Elon Musk becoming emotional in an interview, reportedly about harsh criticism of SpaceX from astronauts.

A one-minute clip of William Shatner trying to describe the awe of space after a Blue Origin flight while Jeff Bezos sprays champagne.

SpaceX's official footage of the CRS-6 Falcon 9 first stage landing attempt, in high resolution and slow motion. It shows the descent and touchdown on the drone ship.

A short test firing of the XRS-2200 linear aerospike engine at NASA Stennis Space Center, which was designed for the cancelled X-33 VentureStar. The engine is shown at roughly 80 percent of max thrust.

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.

SpaceX footage of the Grasshopper reusable rocket prototype flying 325 m before landing on its pad. It was the first test to use the full navigation sensor suite and closed-loop control for a precision landing.

A one-minute clip of an Atlas Agena rocket losing pressure on the pad and collapsing. The Atlas relied on tank pressurization for structural integrity, so a simple failure tore it apart.

SpaceX footage of the Grasshopper vertical takeoff and landing test vehicle making its first roughly 6-foot hop in McGregor, Texas, on September 21, 2012. It was an early step toward a reusable Falcon 9 first stage.

A SpaceX concept animation of a Falcon 9 and Dragon launch with powered vertical return of both stages and the capsule. It was uploaded to YouTube in 2011.

Footage of DC-X Flight 8 from July 1995 at White Sands, in which the Delta Clipper Experimental reusable rocket turned over into a re-entry profile and re-oriented itself for landing.
