You see the big red ball of gas it was turned into. Watch the scene again. That can not be the big chunk of ship we see on Taris in this game how that explosion happened. It was bigger than the ship itself as there was nothing of the ship to see in that explosion.
This is editorial freedom many script writers take. I can think of many examples in Sci Fi where you see a ship "explode" in space, and then later the wreck is found on a planet. Star Wars is certainly not the first nor will they be the last to use a "plot device" like this
