NAIL: Our last question is for Art. It's from Richard from Irving:
How does the ST5 system provide fault tolerance when a satellite becomes inoperable?
AZARBARZIN: Well, first of all, we're trying to make sure that the satellites do not become inoperable.
But we do do a lot of ground testing and we also have designed this spacecraft to be autonomous.
That means in case there's an issue with the spacecraft, they do do power shedding and they do drop,
turn some of the items off so make sure they can conserve energy.
And they also have the algorithm built in so they can point themselves toward the sun and correct the problem.
On the ground, we have built contingencies. Just in case the spacecraft cannot take care of itself,
then we use our contingency procedures to try to correct the problem.
Now, if this does not, inoperable for any reason, the advantage of having a constellation
is if one becomes inoperable, the others can still carry on the mission.
NAIL: We really appreciate your great answers today, gentlemen. Best of luck with the mission.
STEVENS AND AZARBARZIN: Well, thank you very much.
