Mars 2020 is a mission launched in July 2020 to land the Perseverance rover and Ingenuity helicopter on Mars. Perseverance’s design is very similar to that of Curiosity, the rover is even constructed using Curiosity’s spare parts. Compared to its predecessor the new rover is equipped with thicker, more durable aluminum wheels, a new sampling and caching system, and a larger scientific instrument suite. Perseverance also carries Ingenuity, a helicopter drone which is expected to perform several short flights as a technology demonstration. Perseverance successfully touched down on Mars on Feb 18, 2021.

Craft Description

Built for KSPv1.10.1
Requires Breaking Ground DLC
A stock+DLC replica of the Mars 2020 mission, including the Atlas V 541, Cruise and Descent stages, Perseverance, and Ingenuity.

Perseverance features a functional rocker-bogie suspension system, and servo-powered wheels controllable via action groups for driving and steering.
Ingenuity features counter-rotating coaxial rotors and is controlled exclusively through blade pitch and rotor trim.

Update 10/27

The rocket and rover have been updated with slightly more authentic detailing. The rover now features a robotic arm, which comes with a sample collection animation.
Controls have been added for mast head and robotic arm control.

Instructions

Advanced Tweakables

Certain parts of the rover may not work if the Advanced Tweakables option is disabled. To enable it, go into the settings or press Esc and enable it from there.

Flight

Start your gravity turn by pitching up/back, then roll the rocket 180 degrees to assume the proper attitude.
The payload produces a lot of drag, so take a high ascent trajectory. The rocket should hit 45 degrees tilt at 15000m - 20000m.
Jettison the fairing at an altitude of 40000m.
After releasing the cruise stage from Centaur, press 4 to enable RCS control.

Atmospheric Entry/Landing

Before atmospheric entry turn off SAS and press 5 to enable aeroshell RCS. This also reorients the probe core for better landing control.
Turn SAS back on and hold retrograde for the entire landing sequence.
After the parachute has been deployed, stage to release the heat shield. Stage again at 2500m altitude to release the rover and descent stage.
Throttle up to max at 2000m to slow your descent. Once velocity drops to 20 m/s, press 6 to disable the inner 4 descent engines.
Press G to lower the rover on the sky crane. After touchdown, stage to separate from the descent stage.

Deploying Ingenuity

Pressing 7 will unpack the rover and unfold Ingenuity from its stowed position. Stage to decouple Ingenuity from Perseverance and press 2 to drive the rover away.
Switch to Ingenuity and press 1 to enable rotors and blade pitch control. Throttle up to power the rotors. Use H/N to control blade pitch. W/A/S/D controls pitch and yaw, and Q/E controls roll trim.

Driving Perseverance

Perseverance comes with five driving modes, one for driving straight ahead and four for steering left or right at maximum or minimum radius.
Each mode is toggled on/off. Forward mode and any steering mode can be toggled on at the same time, but enabling another steering mode will override the previous.

Arm Control

The robotic arm comes with an animation for sample collection, press 8 to toggle.
You can also control the arm manually- I/K/J/L controls shoulder rotation, H/N controls elbow rotation, and W/S/Q/E controls wrist rotation.
