Lol

NASA tucked up the first rover to Mars because one team used Imperial and the other used Metric. Which is why the first landing was actually a crash.

they just declared it lost do to metric/imperial conflicts when they really blew the research/launch money on hookers and drugs

anybody that took a science or chemisty class in usa knows nasa was always on the metric system

Actually @Deleted User thats not true

The screw up with metric vs imperial is used in computer science courses to understand the importance of validating units used in systems and just how big and costly a simple mistake like that can cause

most of the rocketry scientists from germany via operation paperclip were on metric system...von braun included

well computer systems can be the fault of the programmer, not most scientists

To my knowledge the imperial system was assumed by USA scientists

The system was built by two countries. One built the detector, and the other calculated distance to ground

I dont remember which side built which, but the end result because one used imperial and the other used metric did result in the crash

And was an important lesson on verifying units used in systems.

It turned out to be cheaper to switch the imperial system to metric and that was only programming, the other required changing out hardware I believe

The American and the foreign (i forget which country exactly) BOTH assumed the other was using the same units of measurement and never confirmed before launch.

Why is that not a question

On a multi billion dollar project

@Deleted User
Likely true during early satellite operations, but no longer a valid assumption

@dwagiud it is now

Human error essentially

Did astronauts pass?

who handled the launch and tracking

Not information that was given. It was an example of what happens when you dont verify units being used in a system when building an application and possible consequences of a simple error in design

most likely was usa that handled launch and tracking at the time...to future discredit american space agencies

Just like the case where the robot operator was decapitated by the machine

The base algorithm to calculate how fast the machine would move under power was off due to calculus error. The programmer did not understand calculus. The end result was the machine arm swung through safety limiters and killed the operator

@Deleted User nope just a simple error

in inputs vs outputs

No one was discredited, but there was a lot of facepalming

a liberal error u mean

Neither team verified the units being passed between systems, internal systems on the lander

they want 'workers' and not thinkers so they keep the critical thinking away from the programmers and other worker drones

@Deleted User not true

These exercises are part of the course to teach WHY validation is important

And what simple errors can cost in resources and such

Depends on what your application is for be it a Mars lander or factory robot

in soviet union, they'd build the whole rocket then test it based on an untested design...and keep launching each one til 1 design worked, regardless of the cost in materials and lives

Nasa does not design rockets or new tech. They OPERATE and analyze the results

Look up the space elevator project

but during that same time, nasa and jpl were testing out each and every design til something worked before even building it into a rocket to even launch anything

nasa and jpl used the validation system...soviet space program didn't

I have no data on this information
