Computer Science in Space

“The thundering engines vibrate throughout your body”

Computer scientist Jason Cordes tells us what it was like to work for NASA on the International Space Station during the time of Space Shuttle launches… (read on)

Debugging at a distance (quite a big one)!

NASA’s 50 year old interstellar probe Voyager 1 went silent until computer scientists transmitted a fix that had to travel 15 billion miles! Now it is back to sending scientific data again. Here is how they did it… (read on)

Margaret Hamilton: Apollo Emergency! Count to 5

You have no doubt heard of Neil Armstrong, first human on the moon. But have you heard of Margaret Hamilton? She was the lead engineer, responsible for the Apollo mission software that got him there, and ultimately for ensuring the lunar module didn’t crash land due to a last minute emergency. (read on)

Fencing the moon

The Apollo lunar modules that landed on the moon were guided by a complex mixture of computer program control and human control. One problem was the need to shut off the engines just before touching down. The problem was solved with a cunning (if simple sensor) contraption (read on)

If the Beagle had landed

The Beagle 2 mars probe disappeared as it got to Mars. On board was a work of Art by Damian Hirst and music by Blur. But what happened to them? (read on)

In space no one can hear you …

Johanna Lucht could do maths before she learned language. Why? Because she was born deaf and there was little support for deaf people where she lived. Despite, or perhaps because of, that she became a computer scientist and works for NASA. (read on)

Even the dolphins use pocket switched networks

Why might slow rather than fast networks be important? In space! Under the sea! In a disaster area. In the Arctic! Find out about a different way we could build our networks …(read on)

Core rope memory

Weaving, in the form of the Jacquard loom, inspired Charles Babbage. He intended to use the same kind of punch card to store programs in his Analytical Engine, which had it been built would have been the first computer. However, weaving had a much more direct use in computing history. Weaving helped get us to the moon … (read on).

Make your own core rope memory storing your name or some secret message, as a bracelet or just to hang as a decoration … (read on)

Annie Easley: putting rockets into space

Annie Easley was a pioneer both as a computer programmer but also as a champion of women and minorities into computer science. She went from being a human computer doing calculations for the rocket scientists (in the days before computers were machines), to becoming a programmer whose programs were integral to many NASA projects…(read on)
