Live coverage of the Mars 2020 Perseverance rover launch from NASA’s Kennedy Space Center and Cape Canaveral Air Force Station in Florida. JPL, which is managed by Caltech in Pasadena, is building and will manage operations of the Mars Perseverance rover for NASA. Mars 2020 is part of a larger Moon to Mars exploration approach that includes missions to the Moon as a way to prepare for human exploration of the Red Planet. Perseverance is scheduled to launch aboard a United Launch Alliance Atlas V rocket at 7:50 a.m. on Thursday, July 30, 2020 from Space Launch Complex 41 at Cape Canaveral Air Force Station. The Mars 2020 mission is managed by NASA’s Launch Services Program. — NASA — Mars, Up Close Source: NASA (https://images.nasa.gov/) Licence: Public domain (work of the U.S. federal government, 17 U.S.C. §105) Audio is served by the publisher; Budi does not host or modify it.

6:48next generation of robotic explorers to the Red Planet. And Atlas TU has gone to closed loop control. Coming up on 30 seconds into flight the RD-180 is throttling down as expected, engine response looks good. And Mach 1 Atlas V is now supersonic. And passing 45 seconds into flight, vehicle is now passing through max Q, maximum dynamic pressure. And passing one minute into flight the RD-180 is throttling back up as expected. Engine response looks great. At this time in flight the SRB chamber pressures remain nominal and the RD 180 pump speed and fuel injector pressures are responding well to demands on the engine. Standing by for SRB burnout shortly. We have burnout on all four SRBs. Burnout pressure signatures look good, standing by for SRB jettison shortly.
8:34And we have a good indication of SRB Jettison of all 4 SRB's and the vehicle has gone to closed loop guidance. Vehicle body rates are responding nominally at this time. Coming up on 2 1⁄2 minutes into flight, the RD-180 is throttled down slightly as expected. Engine response continues to look good. At this time the vehicle is 50 miles in altitude, 85 miles downrange traveling at 6,000 miles per hour. Centaur Reaction Control System is now pressurizing to flight levels and just past three minutes into flight the RD-180 is now throttling to maintain a constant two and a half G acceleration limit for payload fairing jettison. Engine response and vehicle acceleration look good. This morning Joshua

The Centaur Reaction Control System is now pressurizing the flight levels and just past three minutes into flight the RD-180 is now throttling to maintain a constant 2.5 G acceleration limit for payload bearing jettison. Response and Vehicle Acceleration look good.
