Perseverance rover starts journey to Mars
The Perseverance rover launched on Thursday, July 30, at 7:50 a.m. ET from Cape Canaveral, Florida, and will begin its long journey to Mars.
Mary God, Shani is grace on me from gun sand with way from sea to I see the beautiful baritone voice of Grammy award winning singer Gregory Porter. Thought was outstanding. Waas so emotional launched the rocket right now, after that season, rockets red glare is perfect. Thank you very much, Mr Porter. We appreciate that. So perseverance will seek to unlock many mysteries about Mars, but remote scientific instruments can only go so far. Joining us now to talk about returning Maher samples back to Earth is Dr Lori Glaze, director of NASA's planetary Science division. Thank you so much for joining us today. My pleasure. Happy? Oh, yeah. First, can you talk to us about the value of studying Mars samples here on Earth? You bet. So, one of most exciting part of this mission, of course, is that we're going to drill samples, that we're gonna go back to Mars and pick up and bring back to Earth. And part of the reason for that is the main reason is that we can only go so far with the instruments that we have on the rover. They're wonderful. It's a great sweet, but nothing compared to the state of the art instruments in the laboratories around the world. So we really want to get those precious samples back here so that we can do that really in depth analysis of the samples here. In addition to that, not only do you want to study him now today, with those state of the art instruments and facilities we can preserve actually most of the sample for decades and that will allow us to use future instruments. I haven't even been invented yet or no answer questions we haven't even thought of yet. So that's it's really important to get those samples back here. And could we confirm life? If if it is there with the incidents we have on the rover with that actually actually happened back on Earth, I fully expect we won't be able to make that real determination until they're back here on Earth. We expect, with the instruments we have on board to be able to detect bio signatures and the types of things that say yes, this is a sample that may contain evidence of past life in the sample, but I think it'll be very difficult to confirm that until we actually get the samples back here on Earth. Speaking of getting them back here to Earth key part of this. How will you do that? That's a great question. We're already starting work on that next mission called Mars Sample Return. We think it's going to launch. We're planning for a launch in 2026. This is a really complex emission. It's going to require two launches from Earth and one launch from Mars in order to get those samples back here. We're working really closely with the European Space Agency, our core partners on this mission. So we'll have a launch from the US, which will lancet launch a sample return lander that will land on the surface carrying a fetch rover that will go out and pick up the samples, bring them back, load them into a rocket the Mars ascent vehicle, and launch them into orbit around Mars at the same time when we launched from Earth. The Europeans are also launching an orbiter from Earth that will be in orbit around Mars. And it will capture those samples with that orbiter. We're going to capture them, and then it will make its return trip back to earth. Release them and they'll come down and land in the Utah desert where we will then safely carry them and put them in the curation facility. Wow! With a process also, that is so amazing. Thank you so much, Laurie, for joining us today. We appreciate our tells you enjoy the launch. Getting Vienna Perseverance go. Ingenuity. Well, In the early 19 hundreds, the Wright brothers proved powered flight was possible on Earth. Now NASA plans to test a powered flight on Mars with an ingenious helicopter. So let's get back out to California. Now. In Richelle, the Martian atmosphere is 99% less dense than here on Earth. So this is no easy task to fly on Mars. This Daryl now hitching a ride on the Perseverance Rover is an exciting technology demonstration. The Mars Ingenuity Helicopter. Now, if successful, it would mark the first time humans have taken powered flight on another planet. Ingenuity is project manager Mimi Young joins us now to talk about the set of milestones ingenuity needs to hit in order to take flight on Mars. Hi, By the way, we just had an earthquake in this room. But anyway, with that um Marcella Copter Tech demo is motivated by the potential of adding the aerial dimension to space exploration. In the future, a helicopter can service a scout for robbers and astronauts. Helicopter can get us to places of high scientific interest that cannot be reached today. It's not easy to build a road, a craft for flight at Mars. The atmosphere there is very thin, but 1% compared to that of Earth. So a helicopter for Mars has to be very light and have a road, A system that can spin very fast. Behind me is the full scale model of MAS helicopter ingenuity. It's very light. 1.8 kilograms, about £4 is capable of flying through the thin atmosphere of Mars and is capable of surviving and operating autonomously. There is a set of milestones between now and ingenuity is first flight. The very 1st 1 is when we turn on the helicopter in the Bay Station to check their health first time operating in true space environment. The next major, my stone, will be when Perseverance Rover deploys ingenuity helicopter to the surface. The deployment will also mark the first moment the helicopter sauce to work on its own in a standalone manner. It will never return to the rover in the first major stone mouth stone. Then will be the helicopter surviving the first cold Martian night, about minus degree, minus 90 degrees Celsius. And we have designed a helicopter to keep itself warm. So we've planned for up to five flights in the 30 Martian days that have been set aside for a flight experiments. The flight data we get from the helicopter will inform our team the health of the helicopter and performance of each flight. The data could also include a few color photos. First ever photos of Martian terrain taken from aero advantage. That would be true icing on our cake. Take me. Thank you. And you're right. We did have a little bit of a shakeup, But everything seems to be okay right here so far. And we look forward to ingenuity is first flight. And with that, let's head back to Casey as we continue the countdown to Mars. All right. Thank you, Richelle. When the name perseverance was chosen for the rover, our country was in the early stages of the cove in 19 pandemic. Now the name is also a fitting description of what NASA teams needed to get this rover to the pad on time. Joining us now is NASA Administrator Jim Bridon Stein. Thank you very much for being here, Jim. Perseverance is meaning a lot. And that includes a recently a 3.9 earthquake that we have reports of in California. We just saw our own Mimi on.

And at Lefty, you have gone to closed Loop Control coming up on 30 seconds into flight. They already won. 80 is throttling down, as expected. engine response looks good, and mark one that was five is now supersonic and passing 45 seconds from the flight vehicles now passing through Max Q. Maximum dynamic pressure and passing. One minute into flight. The rt 1/80 throttling back up as expected, Engine response looks good at this time in flight. The SRB chamber pressures remain nominal. The rt 1 80 Pump speed and fuel injector pressures are responding well to demands on the engine standing by for SRB burnout shortly, and we have burned out on all four srb burnout pressure signatures. Look good standing by for SRB jettison shortly, and we have a good indication of SRB jettison of all four SRB and the vehicle has gone to close loop guidance vehicle body rates are responding normally at this time and coming up on 2.5 minutes from the flight. Ah, already 1/80 throttle down slightly out of expected engine response continues to look good at this time. The vehicle is 50 miles in altitude, 85 miles down range. Traveling at 6000 MPH in the centre Reaction control system is now pressurizing the flight levels. Cape Winds Dave Irwin's met in it and just have three minutes into flight. The already won 80 is now throttling to maintain a constant 2.5 G acceleration limit for payload fairing. Jettison, engine response and vehicle acceleration look good. Everyone's a load bearing jettison and some cardboard forward loaded reactor deck, gentle sink and processed. L. R. Six and L R. Seven to max altitude and you may, and they already won 80 of throttle back Your throttling back up to attain a 4.60 acceleration engine response continues to look good, and center has begun the boost face chill down sequence to thermally conditioned the R L 10 for Operation Copy that standing by for Biko shortly and we have Deco booster engine cut off standing by for stage separation, and we have good indication of Atlas Entire separation and we have met. One. Are all 10 operating parameters Look good Chamber pressures are stable. This will be the first of two burns for today's mission. The first burn will be approximately seven minutes in length, and we have seen the center p U system go to closed loop control. Engine response remains nominal. Still seeing ah stable on nominal chamber pressures and we are beginning to see ah the RCs system. Begin Periodic thermal firings toe maintain conditions in the loop and the Lupin bottle. Temperatures are beginning to converge on nominal temperatures and initial data. Review of Boost flight indicates ah, slightly above nominal performance of the Atlas five booster at this time. The vehicle is 140 miles in altitude, 900 miles down range, traveling at 14,500 MPH. And we did see a minor interruption to telemetry there as we, which to a teacher's compatible data format overall telemetry quality is very good and coming up on eight minutes into flight, beginning to see the center. P u System balance out, uh, math. There's, um, seeing very stable body rates from the center and coming up on 10 minutes into flight. We have seen the P you actuator come off of the locks. The lock spirit stop as expected and still seeing ah stable and nominal operating parameters on the r l 10 there is approximately one minute remaining in the first center burn, and we've had I I vanish. The center is now orbital and we've had Miko one engine cut off pressure signatures look good Center Wilk Coast for approximately 30 minutes prior to the next burn, RCs was now commanding 100%. Settling the settle propellants in the tanks and center is now adjusting its attitude for PT Fi role body rates and RCs performance look good at this time at this time. Center is 2400 miles down range, traveling at 17,300 MPH. And as we passed 13 minutes into flight, be RCs system, temperatures have converged a nominal value. The center tank pressures remained stable and expected values and still think good overall performance from the RCs system passing 16.5 minutes in the flight. Initial review of the Miko one orbital parameters indicate that the vehicle trajectory is very close toe preflight predictions and passing 18 minutes into flight. The RCs system is now commanding 25% settling still seeing nominal operating parameters and temperatures on that system. Also seeing ah nominal unstable battery, voltages and temperatures as well
