Yes, we're all piled higher and deeper.

What if you could build rockets based on MSPaint drawings?

(There's actually a dude who posts in these threads about his hobbyist rocket engine projects)

This is very 4ASS. I approve. You'd also need an external power source to drive the pumps. NASA's attempt to shoehorn water propellant into their classic expander cycle NTP design was a hilarious failure.

Looks like your average /sfg/ regular.

nice to see /sfg/ return to form today

What is the Isp of a fart? Does it improve if you light the fart? How do different beans affect the propulsive properties?
4ASS needs funding for important studies like these.

>and the fact that no one at NASA has launched a proof of concept or even tested a full sized version yet is a mind boggle
Pic related was created for a reason. 4ASS's mission is to do retarded things no one else will fund.

At this rate Big Jim will put out an RFP for MOOSE packs for the ISS.

True, NASA hires teams that all have the same mindset of being social credit points
They need true diversity on their staff

4ASS is contracted by an entrepreneur who want's to sell moon rocks. The goal is to design a lunar lander that could transfer from LEO to the moon, land, recover as many moon rocks and dust as possible, and then return the samples back to Earth. All for as low cost as possible. The launch vehicle will be a Falcon 9 which rides will be purchased by the entrepreneur.

What would the design be?

I'm planning on building a 60% H2O2/Kerosene rocket this summer, with 10-20kg of thrust (depends on what pressure in the chamber I manage to achieve), electrical pump feeding, using gasoline pumps from a regular car and a motorcycle battery to power them. If this works it'd be fucking neat. No need to pressurise tanks for sea level ops (I plan on installing a couple of intakes) and eventually you can evolve the design through the use of better pumps.

How would it look and how would it work?

First for strategically stupid frogposting.
