NASA said non-essential equipment was turned off for the approach. They expect photos in some days. The first orbital revolution period is 53 days. Juno is expected to orbit the planet 37 times keeping an altitude of 5000 kilometres (3100 miles) above the Jovian clouds and then fall into the planet in 2018.
NASA's, launched in 1989, found evidence of saline water on Jovian satellites , , and .
