Not quite, it does produce 4 Plan. Survey Points which is 1 extra Planetary Exploration point if you start in the system.
Can I verify that the rule: 'A ship with operable Science Instruments
or Planet Surveyor (Xp) generates x survey points per StMP spent surveying, based on the quality of Science Instrument.' This means that you can only use either the Science instrument
or the Planetary Surveyor.
Also per R2.02.1 - Only one Science Instrument per ship can generate SPs during an StMP. That only 1 Science instrument could be used will crimp the plan for those who thought to put 2 x Xa on a ship. For those who say that Xp are not science instruments, that is strictly true per R3.01 - 1st bullet point. But they are grouped as science instruments further down and see the first paragraph above. So either way it looks to be that you can use either the Xa or the Xp.
So I would replace the Xp with a (Bsa) and a 'st' for it. The Xa would generate 3 SP and the 'st' would generate 6 Plan. SP for a max. of 3 SP for WP Surveys and 9 SP for Plan. surveys (if it starts the turn in the system). It costs 5 extra MCr to buy this combo instead of the Xp but the maint. cost would be less as 'st' have no maint. cost.
I weary of the chasssse. Wait for me. I will be mercccciful and quick.
