JunoCam breaks com silence with its first shots of Jupiter

JunoCam breaks com silence with its first shots of Jupiter During its tenure around Jupiter, Juno will make some 37 orbits, collecting data on Jupiter’s origins, structure, atmosphere, and magnetosphere.That puts the spacecraft close enough to peer hundreds of miles deep into the obscuring cloud cover of Jupiter.

Where are all the large impact craters on Ceres?

Where are all the large impact craters on Ceres? Astronomers agree with you — most of the rocks in our asteroid belt look pretty careworn.So they expected that when NASA’s Dawn spacecraft got to Ceres, they would see similarly many large impact craters marring the dwarf planet’s surface, just like every other rocky thing in our entire solar system.

Science fiction becomes science fact with a better look at Jupiter’s moon Io

Science fiction becomes science fact with a better look at Jupiter’s moon Io New research from the Southwest Research Institute shows that exactly that process is happening on Io, except on a daily basis.But for two hours out of every day on Io, when Jupiter eclipses the Sun and its warmth, the moon’s surface temperature plummets from the positively summery -235F to a frigid -270F.

Juno makes a death-defying swoop for its first and closest flyby of Jupiter

Juno makes a death-defying swoop for its first and closest flyby of Jupiter It’s all because of the extreme electromagnetic environment around Jupiter.Liquid metallic hydrogen circulating in Jupiter’s interior contributes to the strength of the magnetic fields forming a deadly donut around Jupiter’s equator (we think; Juno is designed in part to confirm or correct this hypothesis).

This week in space: all stuff from inside the solar system, for once

This week in space: all stuff from inside the solar system, for once We don’t have direct access to the core — the best we can do is boreholes and, sometimes, magma.For some years, scientists have been pretty sure that the inner core of the Earth is made of 85% iron and 10% nickel.

This week in space: VR, Juno, and Wavey McWaveface

This week in space: VR, Juno, and Wavey McWaveface The first gravitational wave ever sensed by mankind has a Twitter account, and you people voted to name it Wavey McWaveface.Taken with its JunoCam instrument in the visible spectrum, the image shows the terrible storms and vortices around the turbulent pole.

NASA's Juno will stay in its 53-day orbit around Jupiter after engine troubles

NASA's Juno will stay in its 53-day orbit around Jupiter after engine troubles In light of engine troubles, NASA scientists have determined Juno should remain in its current 53-day orbit around Jupiter.Radiation hardening was one of the main mission considerations when building Juno, as Jupiter’s ludicrous magnetic field is enough to fry even the boldest of spacecraft.
