Launch first satellite to orbit with early technologies.
Launch Mk-1 capsule to low orbit with early technologies.
Allow 200-300kg of stuff (experiments).
I'm surprised I can easi
Include landing stage with RCS as main engine (996 m/s available for descent, you may add stage for deorbit).
Less than 18 tons
Enough delta-v to perform 80x250 km orbit.
Use scientist (on rear command pod)
Include landing stage with RCS as main engine (1400 m/s available for deorbit and descent).
Well CoM balanced RCS powered probe with DTS1 antenna.
Early technologies, less than 30 parts, use RCS as main engine for rendezvous with a station at 100km
Low cost and technologies for station at 100km orbit.
Launcher and 2 crewed spaceship for low orbit around 90km.
Light, less than 17 tons.
Priceless, 8000 credits only.
