- Install MapSat GPS radio
- Verify sufficient power for electric rover (solar panel or RTG that doesn't fall off in dynamic environments)
- Does gear touch the ground when extended?
- Did you pack enough delta-v? (No.)
- Are you planning on returning?
- Is your shit manned or did that little probe body ruin the day?
- How many crew do you want?
- Did you remember ASAS and SAS?
- Is RCS needed?
- Check yo stagin'
- Are you packing parachutes? Do you need to repack them?
- Does the craft need an illumination? For docking? Looking downward for landing? For EVA to be able to find the hatch?
- Adding an antenna on one side of a docking port can help you orient while docking; put one on both spacecraft
- How many crew do you want?
- Can everyone onboard get home if the station has a problem?
- Science modules?
- Food, bathroom, clothes, cupola?
- EVA airlock module?
- Robotic arm(s), are there mods yet for this?
- Radiators?
- Computers? ASAS, SAS (reaction wheels)
- Heating/cooling/CO2 scrubbers (Kerbal resources mods can help here)
- RCS? Ion? ISS has to repeatedly boost its altitude over time
- Lights? Are docking spacecraft well-lit? Is the station well-lit for glamour shots?
- Do the solar panels and batteries provide sufficient power?
- Docking ports: are they positioned with enough clearance for docking spacecraft? Can the station be extended beyond its design?
- BOSS? ISA MapSat or GSP?
- Did you test your lander on the launchpad first?
- Did you time accelerate until the correct phase angle (and leave enough time for docking if applicable)?
- Is there wobble? Back to the VAB to stiffen the launch vehicle, struts or redesign.
- Look up the inclination of the body you intend to visit and calculate your launch heading
- Lock gimbals on non-core engines
- Control from here on the part oriented correctly towards the target
- Set the other spacecraft as the target
- Orient both spacecraft normal and anti-normal respectively to null out the rotation of the body you're orbiting
- Determine if you're going to be docking in the dark and whether or not you have lights and the battry power required
- Remember to roll your spacecraft so RCS thrusters fire as you'd expect
- Set the individual docking port as target once it's visible
- Disable SAS on contact to let the attraction pull both spacecraft into the same orientation
- Polar orbits allow one probe to map an entire body
- Elliptic orbits allow extended time over a particular feature on the surface
- Is the surface even?
- Is it going to be properly illuminated?
- Is there going to be any bodies visible from the landing site? Do you want there to be? Tidal lock?
- Did you read the kspwiki article on your target and its atmospheric data, etc.?
- Check yo stagin'
