Ejector seats AND turbopacks
Unless you secure it to the main spacecraft, so that you only have to spacewalk to it, detach and land. If you're using the mothership to do most of the delta-V intensive maneouvers, you only have to use the lander to go down and up - may be interesting if all you want to do is to ferry crew and cargo to and from the surface and you have a shelter on the ground.
you mean you arent actually in the spacecraft, and for the 5-10 minuted that you're descending, you have the pleasure of decellerating from 1.7km/s +, knowing that if you fall off, you're going to hit the moon at near orbital velocity
and before you say that that wont hapen, remember that during a spacewalk at the ISS, the entire left side of an astronaut's SAFER came detatched during freeflight, rendering it useless :facepalm: anything can happen in spaceflight
