Is this brick from an old Space Explorer set? I cannot seem to find a number on it. Any help to link this brick to a particular LEGO set would be much appreciated.

No. It's older than that.

This element has been in 9 sets, in trans-dark blue (as pictured) it has been in 4: https://www.bricklink.com/catalogItemIn.asp?P=4228&colorID=14&in=A that bricklink says came out in 1981 and 1983

    Technically it only appeared in 3 sets, the 4th listing is an “extra” for one of the first 3 sets.

    That is one big extra.

    @PhilB. To be fair it appears in all 4 sets. The last one doesn't use it to build main model however, but is required to build a "super model". This "super model" is using elements from two more sets: 6880 and 6929, according to Brickset.
