At the Jet Propulsion Laboratory, leadership is steering this storied institution through an unusually rocky period
suffered a navigation error and disintegrated as it plunged into the Martian atmosphere. Three months later, the Mars Polar Lander went silent during its descent and presumably crashed at high velocity.
To pull off these missions requires flashy hardware and sophisticated software. There’s a lot of code in the critical path. Postdoctoral student Michael Bramble operates a machine that simulates conditions on Europa to help engineers understand what the Clipper spacecraft might observe.Mechanical engineers Edmund Navalta, left, and Morgan Montalvo work jointly on a lander in a simulation room at JPL.of Mars, scrutinized in laboratories, could lead to a revision of the solar system’s history — and might even preserve the first compelling evidence of extraterrestrial life.
Then the landing vehicle must turn itself into a launch vehicle that will blast into Mars orbit, where the payload will be gobbled up by an orbiter built by the ESA. That spacecraft will rocket back to Earth and drop the samples in the Utah desert for very careful analysis in tightly sealed laboratories.“This will be the most-watched extended mission in history at NASA,” Leshin said.
— said the problem with the software should have been detected earlier, to give the team enough time to fix the issue and still make the launch date. A delay isn’t the worst thing that can happen to a mission, she suggested: “The team raised its hand and said, ‘We’re not going to make it.’ It’s way better to raise your hand before you launch.”
