I heard that Honeywell was working on a 32 bit processor for deep space
missions - RH32? It was supposed to be sufficiently rad-hard and had its
instruction set pruined for a higher level of determinism. I've not
heard if a) it has made its way into production, b) found much
acceptance or c) had an Ada compiler ported to it.

The 1750 may still be the only available game for deep space at the
moment. I had heard that Plessey stopped making their rad-hard version.
(They kept threatening to do this unless we gave them more money.) I
think LockMart may have one they build for themselves. The 1750 may be
1970's technology, but it seems to refuse to die - more from lack of a
successor than anything else.
