On what UTC date did Juno enter orbit around Jupiter?

Juno entered orbit around Jupiter on July 5, 2016, UTC.

NASA’s Juno spacecraft arrived after an almost five-year journey that began with its launch from Cape Canaveral on August 5, 2011. During orbit insertion, Juno fired its main engine for about 35 minutes, slowing enough for Jupiter’s gravity to capture it.

The insertion burn began and ended in the early hours of July 5 UTC, with confirmation received at 03:53 UTC. In the United States, the event was still July 4, which explains why some reports give July 4 as the date. The question specifies UTC, making July 5 the canonical answer.

Juno initially entered a highly elliptical polar orbit lasting about 53.5 days. Its instruments were designed to study Jupiter’s gravity, magnetic field, atmosphere, auroras, and deep interior. Unlike Galileo, Juno was powered by solar panels, a significant engineering achievement at Jupiter’s great distance from the Sun.
