Yes, it is expensive, as your freezer has to be set at temperatures below -80°C/-112°F, down to -196°C/-321°F, and maintained this way for decades without single interruption.

This requires expensive equipment and draws insane amounts of power, and also necessitates multiple power backups.

There is currently no way to do it on a budget.

Launch the capsule into space in an orbit around earth that's always obscure from the sun?

Not a "budget" option but definitely a hell lot cheaper in the long run (decades, or even centuries).

TIL things still get hot in space under direct sunlight. I always assumed space would be cold even in sunlight but apparently not.

anyway, I would think you could still be in a sunlit orbit as long as you had a reflective shield for shading. You'll probably still need power to maintain temps and monitor status, so solar energy would still be helpful.

Fun fact! During the Apollo flights to and from the Moon, the spacecraft would perform “Passive Thermal Control” or “barbecue roll” where it would rotate around its long axis about once per hour, to distribute the thermal load from the sun and keep one side from heating up too much
