NASA officials have determined that the robotic InSight lander is ready for its mission to Mars after concluding that the probe should not suffer the same flaw that led to a crack in a heat shield undergoing tests for the space agency’s Mars 2020 rover, InSight’s chief scientist said Monday.

A flight demonstration of an inflatable heat shield that could be used to retrieve reusable engines from United Launch Alliance’s next-generation Vulcan rocket, and for the delivery of heavier cargo to the surface of Mars, is planned for launch in late 2021 or early 2022 as a piggyback payload on an Atlas 5 rocket with a NOAA weather satellite.
