Video: Juno’s countdown to Jupiter

An Intelsat communications satellite launched last August entered service Sunday, about three months later than planned after a main engine problem forced engineers to position the craft in geostationary orbit using backup low-thrust rocket jets.

Desperately needing a successful deployment to modernize the communications infrastructure for its citizens, Mexico is counting on the Atlas 5 rocket to safely launch a new satellite Friday.

The first months of observations of the solar system’s biggest planet from NASA’s Juno spacecraft have revealed huge swirling polar cyclones, previously-undetected structures and motions beneath Jupiter’s distinctive clouds, and the first evidence for what lies at the core of the gas giant, scientists said Thursday.
