Hint 1 of 7:
The spaceship requires electric power to open.

Hint 2 of 7:
There's a power plant that you need to turn on first.

Hint 3 of 7:
And set it to the proper voltage.

Hint 4 of 7:
That's 59 volts.

Hint 5 of 7:
If you go down to the power plant, you'll notice that each of the buttons
will add a different voltage to the total.  See the next hint to figure out
what those voltages are.
