    The plan was to do a mid course correction around day 15 also.

    They have carried it out. High lights mine,

    NASA’s Mars 2020 Perseverance rover launched from Cape Canaveral on July 30, following successful launchings with the United Arab Emirates’ Hope orbiter July 19 and China’s Tianwen 1 Mars mission July 23.

    The missions launched during a period of several weeks when Earth and Mars were in the right positions in their orbits around the sun to permit a direct route between the planets. All three spacecraft are due to arrive at Mars in February 2021.

    NASA said Aug. 14 that the Mars 2020 mission’s first trajectory correction maneuver, or TCM, was a success. The spacecraft fired eight thrusters to adjust its course toward Mars, beginning to shift the probe’s initial post-launch aim point on to the Red Planet.

    "Sensors on Mars 2020 Spacecraft Answer Long-Distance Call From Earth"

    https://www.marsdaily.com/reports/Se...Earth_999.html

    On Oct. 8, 2020, with COVID-19 safety protocols in place, team members of the Mars 2020 Perseverance rover mission waited for a reply from the Mars Entry, Descent, and Landing Instrumentation 2 (MEDLI2) suite onboard the spacecraft, which is currently en route to the Red Planet.

    MEDLI2 is a collection of sensors that will measure aerothermal environments and thermal protection system material performance during the atmospheric entry phase of the Mars 2020 mission.

    The sensors successfully passed a battery of environmental tests before being installed on the Mars 2020 heat shield and backshell to ensure they could withstand launch and the harsh conditions of space.

    During the recent MEDLI2 cruise checkout, the team at the Flight Mission Support Center at NASA's Langley Research Center in Hampton, Virginia, received data back from the spacecraft for the first time since the rover launched in July.

    "This is the first time MEDLI2 has been tested since before launch," said Henry Wright, MEDLI2 project manager. "The test went great; we got the data we wanted, and everything looks like we predicted it would."

    There was supposed to be a second mid course burn ~30 Sep 20, but I have been unable to find out if it was executed or abandoned. Have any of your sources printed an answer?

    I could not find any. Sorry.

    "NASA's Perseverance Rover Is Midway to Mars"

    https://www.marsdaily.com/reports/NA..._Mars_999.html

    NASA's Mars 2020 Perseverance rover mission has logged a lot of flight miles since being lofted skyward on July 30 - 146.3 million miles (235.4 million kilometers) to be exact. Turns out that is exactly the same distance it has to go before the spacecraft hits the Red Planet's atmosphere like a 11,900 mph (19,000 kph) freight train on Feb. 18, 2021.

    "At 1:40 p.m. Pacific Time Tuesday Oct 27, our spacecraft will have just as many miles in its metaphorical rearview mirror as it will out its metaphorical windshield," said Julie Kangas, a navigator working on the Perseverance rover mission at NASA's Jet Propulsion Laboratory in Southern California. "While I don't think there will be cake, especially since most of us are working from home, it's still a pretty neat milestone. Next stop, Jezero Crater."

    "NASA's Perseverance Rover 100 Days Out"

    https://www.marsdaily.com/reports/NA...s_Out_999.html

    On Nov. 9, the mission team confirmed that the propulsion subsystem of the descent stage, which will help lower the rover onto Mars, is in good working order. Today, Nov. 10, they turn their attention to the rover's PIXL and SHERLOC instruments.

    The Lander Vision System is scheduled to go under the microscope on Nov. 11; and the SuperCam instrument, the day after that. Down the road, on Dec. 18, the team plans to perform a trajectory correction maneuver, using the cruise stage's eight thrusters to refine the spacecraft's path toward Mars.

    The mission has already held several test scenarios to help evaluate procedures and train Mars 2020 mission controllers for important milestones to come. During some of these multi-day-long tests, the team encounters unexpected challenges thrown their way by colleagues who play the role of "gremlins." Even with the challenges introduced during a landing rehearsal back on Oct. 29, the team was able to successfully land a simulated Perseverance rover on Mars.
