NASA launches mission to explore why Earth supports life and other planets don’t – Devdiscourse

A sounding rocket carrying NASA’s Endurance mission launched today to investigate Earth’s life-supporting secret – why does our planet support life, when other planets like Venus and Mars don’t? The rocket launched from Ny-Ålesund in Svalbard, Norway on May 11, 2022, at 3:31 a.m. local time.
“The flight was a splendid success. Everything deployed just as it should (8 booms, 1 hinged sensor, and 2 sprung-loaded caps that all had to come out in time). We got fabulous data all through the flight, though it will be a while before we can really dig into it to see if we achieved our science objective or not. After 6 years of hard graft, watching Endurance take flight was a dream come true,” said Glyn Collinson, the mission’s principal investigator in a statement.
That’s one for sounding rockets!

Earth’s twin planet – Venus – was once much wetter than it is today, but it dried out for reasons scientists still don’t fully understand. Figuring out why could pinpoint a key difference from Earth – and reveal a hidden ingredient for a habitable planet, NASA says.
According to NASA, the Endurance mission will attempt to measure Earth’s global electric potential – how much Earth’s electric field “tugs” at electrically charged particles in our air? This electric potential is expected to be very weak, making it difficult to measure – and one reason Earth can support life.
The mission will measure electrons escaping from Earth’s atmosphere. These electrons escape Earth at a specific, predictable speed, but they should be slowed ever so slightly by Earth’s global electric potential.
