So we saw a little blip uh the data stream indicating the crusade separation. We have confirmation that the vehicle has started warming up those entry thrusters. What pulses have begun Music. At this point, the spacecraft is trying to stop its spin from the cruise two revolutions per minute down to zero and then we’ll turn to its desired orientation from entry. It will separate the two balance map that has kept it balanced during all of cruise. This will allow the entry capsule to have lift when it enters the atmosphere. We have competition that has turned to the desire entry attitude. We are about seven and a half minutes from entry interface. Okay, the vehicle is pointed in the right direction. Thrusters are warmed up and doing their job, and now, if we’ve spun down from two revolutions per minute, that the vehicle had the whole way to on the way to mars is a spin, stabilized spacecraft and then from here on out it’s going to just be a Bullet and it’s going to control its orient orientation and attitude via rockets. On the back of that points, carrier lock, that’s dte from uh radio science from green bank reports carry a lot. Do you see the carrier on the downlink level one? We are continuing to wait for entry interface for about six minutes and 45 seconds from entry interface. We have confirmation from uh greenback that they are receiving direct earth telemetry via that path.

The spacecraft perseverance is currently transmitting heartbeat tones. These tones indicate that perseverance is operating normally and has nothing significant to report. This is as expected, we’re currently just over six minutes from entry interface. Okay, and now we wait as soon as we get to the top of the atmosphere. The atm will be very quickly, which is the entry point. It won’t be very long before the the atmosphere will start getting thicker and thicker it’s going very quickly at a at a fairly steep angle of 15 degrees into the atmosphere as it starts to slow down. Just under uh about five and a half minutes from entry interface, we’re still receiving heartbeat tones uh, we expect to continue receiving heartbeat tones until about five minutes after entry. At that time, perseverance will be no longer in view of our antennas here on earth. About 90 seconds prior to entry, the mars reconnaissance orbiter should begin receiving telemetry from perseverance and streaming it to earth in near real time. There are a few expected short outages, such as when we have a plasma back out or when we enter the peak heating phase. Aside from these outages caused by the plasma blackout, antenna, switching or high dynamic events, spacecraft events, we should have telemetry until about 90 seconds after landing. A plasma blackout is when the signal from perseverance isn’t strong enough to make it through the superheated super fast air flowing around the spacecraft, all the way down to earth.

Once the temperature drops below that peak heating, we do reacquire the signal from perseverance. We are currently about four and a half minutes from entry. Intervase perseverance continues to report heartbeat tones indicating everything is nominal. Okay. What we wait! What we’re looking for now is where mars reconstance orbiter should be in view soon of our vehicle and be able to listen to ones and zeros. Coming from a separate radio, that’s really designed to talk between spacecraft camera reports, the electro radio is powered on ready to receive signals from the lander. Okay, mro is ready and less enabled and waiting for the to hear from our rover mars. Reconnaissance orbiter has reported that it’s ready to receive the signals from perseverance. It should be in a few minutes here: we’re just flight, local ones, from entry interface. We don’t need these ones and zeros as what he said, but to land safely, but we really need it for our own health and well being today to keep our nerves in control around this time. A second spacecraft maven should begin picking up telemetry from perseverance and will continue to record that telemetry until several minutes post landing. We won’t get that data for several hours after landing as it’s being recorded and then will be forwarded to earth. Later we are continuing to receive heartbeat tones indicating that everything is nominal we’re currently at about three minutes until entry interface, okay, very soon, we’ll be getting ones and zeroes.

I hope from our radio on the rover. The entry interface is nothing more than just an arbitrary place in the sky that we’ve defined to be above the atmosphere, but but from that point on uh there’s, definitely uh atmosphere and above it there isn’t. There are two minutes from entry: interphase presidents, it will transmit heartbeat tones indicating everything is phenomenal, so the tones can tell us whether something is bad or not is happening so so far the heartbeat is is doing well, so the vehicle thinks it’s help it’s in good Shape to land is a great sign, uh we’re, just under two minutes from entry interface as it gets closer to mars, preservance is actually being pulled in by gravity and accelerating by the time perseverance reaches entry interface point he should be going just under 5.4 kilometers per Second we’re, at about 90 seconds from entry interface and standing by for mars reconnaissance orbiter to pick up the telemetry Music. We are one minute from entry interface, Music. We have confirmation that the confidence orbiter is now relaying data from perseverance we’re about 30 seconds from entry interface. Procurement is going about 5.2 kilometers per second and is about 190 kilometers altitude above the surface of mars, to confirm your data flow 5.3 kilometers per second and an altitude of 150 bombers from the surface mars Music. We have confirmation of entry. Interface. Pressurance is currently going 5.3 kilometers per second at an altitude of about 112 kilometers from the surface of mars.

The fifth is now waiting until it begins feeling the atmosphere slow it down. Once there is enough atmosphere, it will start controlling its path to the landing target. Navigation is also confirming that we can see a little bit of that slowdown of the atmosphere on the perseverance entry capsule. Our current velocity is about 5.36 kilometers per second and an altitude of about 67 kilometers from the surface. We are probably seeing mro plasma blackout at this point. The vehicle should be doing its turns right now. Camera has lost lock. We have indications that perseverance is now performing bank reversals in the atmosphere. These are the steps in order to control its distance to the landing target. Perseverance has just passed through the point of maximum deceleration and has indicated that it felt approximately 10 earth gs of deceleration. Amarillo has locked again. Yes, yes, yes, yes, we saw a small outage. Uh of the uhf telemetry from mars reconnaissance orbiter during that peak heating phase likely caused by the plasma blackout, perseverance, is still continuing to perform bank reversals in the atmosphere to control its distance to the landing target. Perseverance is going about one kilometer per second, at an altitude of about 16 kilometers. From the surface of mars, we have entered heading alignment, which means preservance is no longer trying to control the distance to mars, but ends to the target on mars, but instead is flying straight to the target Music parachute. Our current velocity is about 550 meters per second.

At an altitude of about 15 kilometers from the surface, amaro is reporting good, telemetry log. We are coming upon to straighten up. We are starting to straighten up and fly right maneuver, where the spacecraft will jettison the entry balance masses in preparation for parachute deploy and to roll over to give the radar a better look at the ground. The navigation has confirmed that the parachute has deployed and we are seeing significant deceleration in the velocity. Our current velocity is 450 meters per second at an altitude of about 12 kilometers from the surface of mars. First, advance has now slowed to subsonic speeds and the heat shield has been separated. This allows both the radar and the cameras to get their first look at the surface. Current velocity is 145 meters per second and an altitude of about 10 km. Nine and a half kilometers above the surface – yes, yes, yes, first now has radar lock on the ground. Current velocity is about 100 meters per second 6.6 kilometers of the surface charge. Applause perseverance is continuing to descend on the parachute we are coming up on the initialization of terrain, relative navigation and subsequently, the priming of the landing engines. Our current velocity is about 90 meters per second at an altitude of 4.2 kilometers. Almost there. We have confirmation that the lander vision system has produced a valid solution and part of terrain relative navigation Applause. We have timing of the landing engines. Current velocity is 83 meters per second at about 2.

6 kilometers. From the surface to mars. We have confirmation that the back shell has separated. We are currently performing the divert maneuver current velocity is about 75 meters per second at an altitude of about a kilometer off the surface of mars. Here in safety. Bravo, we have completed our terrain. Relative navigation. Current speed is about 30 meters per second altitude of about 300 meters off the surface of mars. We have started our constant velocity accordion, which means we are conducting the sky crane about to conduct the fly. Crane maneuver we’ve lost direct to earth to tones as expected as expected. Skycam maneuver has started about 20 meters off the surface we’re getting signals from mro Applause ready to begin seeking the sands of past life Applause.
