Io, Europa, Africa and newborn iceberg

in #space6 years ago

News from the Solar System.  Juno spacecraft, orbiting Jupiter,  captured this image on Sept 1 2017 during its eigth flyby of the gas giant. Juno's orbit has form of elongated ellipse and never get close to Jupiter's moons. Juno studies core parameters of Jovian system so these images are for the PR only. At  the times the image was taken, Juno was 27 500 kilometers from the tops of the Jupiter's clouds, 481 000 kilometers from Io and 730 000 kilometers from Europa.

Fresh detailed images of Io and Europa we'll see only in the end of the next decade when missions Juice and Europa Clipper will arrive at Jupiter

The next picture is satellite's map of the Africa, combined of 180 000 images taken by Sentinel-2A satellite between December 2015 and December 2016. Colors are explained on the picture

And the last one is newborn Antarctic iceberg, recently calved from Pine Island Glacier - one of the main gateways, where icebergs from West Antarctic Ice Sheet flow into the ocean. 185 square kilometers iceberg, named B-44, went afloat in the end of September. Natural-color image with iceberg drifting in Amundsen Sea was captured on September 28 by Landsat 8 satellite.
