Every Ship That Has Carried Humans Into Space, In One Chart

Space is big, humans are small, and spacecrafts, well, vary more in size than you might think. Redditor Heaney555 has compiled an a chart, to scale, of every rocket, spacecraft, and space station involved in human spaceflight. And man, Saturn V is huuuuuuuge — it’s as long as the whole International Space Station.

The Surprisingly Low-Tech Way NASA Decides When To Blow Up A Rocket

When the Antares rocket exploded seconds after launch on Tuesday night, NASA was able to account for all its employees very quickly after the failure thanks to a clearly very well-practised protocol. The launch gave us a peek into the processes that dictate every rocket launch, and one of them was particularly surprising.

World's Most Badass GoPro Doesn't Even Blink At Up-Close Rocket Testing

Video: When it comes to punishing GoPros, Copenhagen Suborbitals definitely takes the cake: The experimental rocket-building start-up mounted an action cam right in the line of (literal) fire during a rocket test. Astoundingly, the thing survived. It’s been to hell and back, and it has the video to prove it.

SpaceX Rocket Exploded In The Air During A Test Launch

Video: Well, that’s not supposed to happen. A SpaceX rocket exploded during a test flight in Texas earlier today. This was the second test for the three engine version of SpaceX’s reusable Falcon 9 rocket. There were no injuries.

Monster Machines: America's Next Big Space Launch Rocket Is A Total Beast

With its forthcoming Space Launch System, NASA hopes to send astronauts farther into space than it ever has ever before — to Mars and beyond. And when the first crew does leave to make interplanetary history, they will do so aboard these rocket engines.

The Amazing System That Tested The Most Powerful Rocket Engine Ever

A photo of the Rocketdyne F-1 rocket engine — “the most powerful single-nozzle liquid-fuelled rocket engine ever flown” — being tested at the Marshall Space Flight Center, Alabama. Five of them powered the first stage of the Saturn V. Watch and listen to all of them being tested — in Dolby 5.1 sound. It’s amazing.

This Is The Rocket That Will Allow SpaceX's Dragon V2 To Land Anywhere

This is the SuperDraco thruster. According to SpaceX, eight of these engines will allow the Dragon V2 spaceship to land anywhere in the planet with the same accuracy of an helicopter. Here you can see it in action, during the last test of its final certification.

How To Make Bottle Rockets With Liquid Nitrogen And Water

This guy builds rockets with bottles and water, adding liquid nitrogen, turning them upside down and boom, instant propulsion: the nitrogen expands very fast on top of the warmer water, turning violently into gas and pushing the bottle up.

The World's Fastest Model Rocket Car Just Hit 458km/h

A toy car could easily break the sound barrier — or go even faster — in a kid’s spirited imagination. But back in reality it takes more than that. You need engineering, patience, and a handful of rocket model engines — all of which helped Samvir Thandi’s SST-3B-Falcon rocket hit a top speed of 462.831km/h.

If You're A NASA Engineer You Get To Play With Toys Like These

If you’re a NASA engineer, you get to play with a lot of awesome toys, like these furious mini-rockets. They are models of the Space Launch System (SLS) core stage engines, “scaled down to just 2 per cent of the actual size of the flight hardware”.
