141-Page PDF Circa 2003 by @NASA of Conceptual ‘In-Space Vehicles’ for Planetary Exploration
I stumbled upon this doc in the NASA NTRS archives. It’s dated November 2003 and proposes ‘five concept missions,’ along with some of the vehicles and engines – and a lot of graphs and math required – to achieve a positive outcome of ‘Human Exploration of the Outer Planets.’ Awesome!
Since its founding, NASA has been dedicated to the advancement of aeronautics and space science. The NASA Scientifi c and Technical Information (STI) Program Offi ce plays a key part in helping NASA maintain this important role.
The NASA STI Program Offi ce is operated by Langley Research Center, the lead center for NASA’s scientifi c and technical information. The NASA STI Program Offi ce provides access to the NASA STI Database, the largest collection of aeronautical and space science STI in the world.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
