Reply to comment by quetric in Why do sample return missions such as OSIRIS-REx use their own reentry vehicles instead of just going to the space station for pickup and return with ISS equipment? by PromptCritical725
Eh, you would design your approach so you intersect the ISS orbit at your perigee. Then decelerate just enough to get a highly eccentric orbit (or a weakly stable one), match inclination at apogee and then decelerate further at perigee.
Still, that would require a restartable motor with >4km/s delta V, which implies at least like 80% of your vehicle being storable propellants. A heat shield is simply lighter.

And not to forget, a bit reason why all of those countries don't want to give up that land is that the area kurdistan would cover is very rich in oil.

It is a 12VDC connector. At 600W that means 50A up, 50A down. 8.3A per pin. And that's assuming it's all perfectly balanced, which with these connections, it won't be.

Additional note, it is 100x smaller in linear size, which puts it around the order of a million times lighter than the chicxulub asteroid.
