This should be 'Touch', otherwise the spell only affects you.

What if the Target is a planetoid?

Can this spell be cast on (1 SJ ton+) living creatures?

2/rnd = 20/min = 120/hr = 240/2hr

in 2hrs 1,200 will have consumed 2,400 man hours of air

I think you want 20 man-hours per round.

Presumably this will start with an air bubble at the centre of
the ship, after one round 2,160 cubic feet (20 man-hours), then
+2,160 cf per round.  One SJ ton has an air bubble 21,600 cf, so
it will be ten rounds (one minute) to reach this size.  A 100 tn
ship has an air bubble 2,160,000 cf, so one thousand rounds (a
hundred minutes) to replace this.

A man-hour is 108 cubic feet of air, which some googling makes
look about right, in RW terms.

Do you want to add that only one Endless Atmosphere spell can be
in effect on one object at a time?

Not sure if you think that this matters...
