CAPE CANAVERAL, Fla. — NASA on Monday approved next month’s launch to Jupiter’s moon Europa after reviewing the spacecraft’s ability to withstand the intense radiation there. Questions about the reliability of the transistors on the Europa Clipper spacecraft arose earlier this year after similar problems cropped up elsewhere. With the tight launch window looming, NASA rushed to conduct tests to verify that the electronic parts could survive the $5 billion mission to determine whether the suspected ocean beneath Europa’s icy crust might be suitable for life. Liftoff remains scheduled for Oct.
