Swipe to see the swirling Jovian cloudscape, courtesy of our Juno spacecraft (@nasajuno)! Captured on May 19, these images show waves of turbulent clouds that dominate Jupiter’s atmosphere. Details as small as 4 miles across can be identified here. See those small, bright, high clouds? They’re about 16 miles across and in some areas appear to form “sqall lines” – a narrow band of high winds and storms associated with a cold front. On Jupiter, clouds this high are almost certainly comprised of water and/or ammonia ice.
The small bright clouds that dot Jupiter’s entire south tropical zone (3rd image) appear tiny, but actually tower roughly 30 miles wide and 30 miles high and cast shadows on the clouds below. It’s possible that these clouds may be sources of lightning. This is the first time so many cloud towers have been visible, possibly because the late-afternoon lighting is particularly good at this geometry.

Hellllooooo planet Earth! NASA astronaut Jack Fischer excitedly waves to the camera during Tuesday’s spacewalk on the International Space Station (@iss). From 250 miles above our home planet, Fischer and astronaut Peggy Whitson performed a contingency spacewalk to replace a failed data relay box. During their 2 hour 46 minute spacewalk, they were also able to install a pair of antennas on station to enhance wireless communication for future spacewalks.

The swirling brushstrokes of Jupiter’s mysterious cloud tops can be seen in this enhanced color view taken by the JunoCam instrument on our Juno spacecraft. In it, you can see a massive counterclockwise rotating storm that appears as a white oven in the gas giant’s southern hemisphere.

Early in the morning on May 19, the Juno spacecraft made its fifth science flyby over these cloud tops, and got as close as about 2,100 miles. Juno is probing beneath the obscuring cloud cover of Jupiter and studying auroras to learn more about the planet’s origins, structure, atmosphere and magnetosphere. At the time of perijove (defined as the point in Juno’s orbit when it is closest to the plent’s center), the spacecraft had logged 63.5 million miles in Jupiter’s orbit.

Shrouded in clouds today in 1969, this image was taken by the crew of Apollo 10 as they began their lunar journey. From 36,000 nautical miles away, this full disk view of our home planet shows the crew’s vantage point from space.

The crew members on Apollo 10 were astronauts Thomas P. Stafford, commander; John W. Young, command module pilot; and Eugene E. Cernan, lunar module pilot. Astronaut Young remained in lunar orbit, in the Command and Service Module (CSM) “Charlie Brown”, while astronauts Stafford and Cernan descended to within nine miles of the lunar surface, in the Lunar Module (LM) “Snoopy”.
