Will Perseverance be captured into Mars orbit before descent or would it be a direct descent into the atmosphere similar to an aerocapture maneuver? It would be helpful if someone could add any references to the orbit trajectory around mars before the descent into the atmosphere!
No. Perseverance will not enter Martian orbit before descent. It would be a direct descent. For reference, here's a picture of Perseverance's landing procedure.
A spacecraft entering into orbit before descent requires a fair bit of fuel. The thrusters on the Backshell are only there for mid-course corrections and for stability during descent. It does not have the delta-v to slow down enough to enter Martian orbit. Also, what would be the need to enter orbit? Mars rotates, so the trajectory is designed to intercept the surface at the desired location. So of course, accuracy is very important. If the spacecraft arrives 6 hours later for example, it would be thousands of kilometers off from the landing site because of the rotation of Mars. Though there is the guided entry phase which can to some degree control where the spacecraft will land.
