Juno is a PI-led mission to Jupiter, the second mission in NASA's New Frontiers Program.
The 3625-kg spacecraft spins at 2 rpm and is powered by three 9-meter-long solar arrays …

Until recently, observations of the giant planets of our Solar System were confined to
sampling relatively shallow regions of their atmospheres, leaving many uncertainties as to …

On 27 August 2016, the Juno spacecraft acquired science observations of Jupiter, passing
less than 5000 kilometers above the equatorial cloud tops. Images of Jupiter's poles show a …

Oxygen is the most common element after hydrogen and helium in Jupiter's atmosphere,
and may have been the primary condensable (as water ice) in the protoplanetary disk. Prior …

The Juno microwave radiometer measured the thermal emission from Jupiter's atmosphere
from the cloud tops at about 1 bar to as deep as a hundred bars of pressure during its first …

Jupiter's atmosphere has a system of zones and belts punctuated by small and large
vortices, the largest being the Great Red Spot. How these features change with depth is …

The Juno spacecraft has been in orbit around Jupiter since 2016. Two flybys of Ganymede
were executed in 2021, opportunities realized by evolution of Juno's polar orbit over the …

Jupiter is the source of the strongest planetary radio emissions in the solar system.
Variations in these emissions are symptomatic of the dynamics of Jupiter's magnetosphere …

We present five epochs of WFC3 HST Jupiter observations taken between 2009–2016 and
extract global zonal wind profiles for each epoch. Jupiter's zonal wind field is globally stable …

Water and ammonia vapors are known to be the major sources of spectral absorption at
pressure levels observed by the microwave radiometer (MWR) on Juno. However, the …
