NASA's Juno mission, the solar-powered robotic explorer of Jupiter, has completed its five-year prime mission to reveal the inner workings of the solar system's biggest planet. Since 2016, the spacecraft has flown within a few thousand kilometers of Jupiter's colorful cloud tops every 53 days, using a carefully selected array of instruments to peer deeper into the planet than ever before.
The most recent findings from these measurements have now been published in a series of papers, revealing the three-dimensional structure of Jupiter's weather systems—including of its famous Great Red Spot, a centuries-old storm big enough to swallow the Earth whole.
Before Juno, decades of observations had revealed the famous striped appearance of Jupiter's atmosphere, with white bands known as zones, and red-brown bands known as belts.
The Parkes dish is still making breakthroughs 60 years after it first gazed at the skies

The CSIRO's 64-meter Parkes Radio Telescope was commissioned on October 31 1961. At the time it was the most advanced radio telescope in the world, incorporating many innovative features that have since become standard in all large-dish antennas.
Through its early discoveries it quickly became the leading instrument of its kind. Today, 60 years later, it is still arguably the finest single-dish radiotelescope in the world. It is still performing world-class science and making discoveries that shape our understanding of the Universe.
The telescope's origins date back to wartime radar research by the Radiophysics Laboratory, part of the Council for Scientific and Industrial Research (CSIR), the forerunner of the CSIRO. On the Sydney clifftops at Dover Heights, the laboratory developed radar for use in the Pacific theater. When the second world war ended, the technology was redirected into peaceful applications, including studying radio waves from the Sun and beyond.
In 1946, British physicist Edward "Taffy" Bowen was appointed chief of the Radiophysics Laboratory. He had been one of the brilliant engineers, dubbed "boffins," who developed radar as part of Britain's secret prewar military research.
ExoMars rover comes out of the ‘oven’

The Rosalind Franklin rover that will search for life on Mars has completed an important bakeout to help clean the rover from organic molecules from Earth.
The rover sat inside a vacuum chamber for 120 hours at 35ºC at the Thales Alenia Space facility in Rome, Italy. The temperature is enough to sublimate hidden contaminants generated by the off-gassing of some of the rover’s internal parts, such as small bits of glue. The goal is to reduce as much as possible any contamination signature of Earth origin, to allow a clean detection of organic compounds on Mars.

Leicester study of data captured in orbit around Jupiter has revealed new insights into what's happening deep beneath the gas giant's distinctive and colourful bands.
Data from the microwave radiometer carried by NASA's Juno spacecraft shows that Jupiter's banded pattern extends deep below the clouds, and that the appearance of Jupiter's belts and zones inverts near the base of the water c Capabilities growth shows why US sees China as pacing challenge

Army Gen. Mark A. Milley pointed to China's recent test of a hypersonic weapon system as an example of why the U.S. military is concerned about Chinese intentions.
The chairman of the Joint Chiefs of Staff spoke on Bloomberg News' David Rubenstein Show and said DOD officials saw the test as "a very significant event."

In a weightless, microgravity environment like space, what do ability and disability look like? How can someone with partial sight or impaired mobility navigate in a confined space like the space station? As scientists and innovators continue to push the boundaries of spaceflight and the possibility of human life on other planets, how can we build space infrastructure that is inclusive of all hu Jupiter's Great Red Spot is deeper than thought, shaped like lens

New studies of Jupiter's Great Red Spot released Thursday have found that while the meteorological phenomenon is deeper than originally thought, it's largely shaped like a flat lens about 10,000 miles wide.
The vortex storm, the largest of many such spots on Jupiter's surface, extends up to 310 miles below the planet's cloud tops, some 100 miles deeper than previous research indicated. Science results offer first 3D view of Jupiter's atmosphere

New findings from NASA's Juno probe orbiting Jupiter provide a fuller picture of how the planet's distinctive and colorful atmospheric features offer clues about the unseen processes below its clouds. The results highlight the inner workings of the belts and zones of clouds encircling Jupiter, as well as its polar cyclones and even the Great Red Spot.

Using the Advanced Photon Source, scientists have recreated the structure of ice formed at the center of planets like Neptune and Uranus.
Everyone knows about ice, liquid and vapor - but, depending on the conditions, water can actually form more than a dozen different structures. Scientists have now added a new phase to the list: superionic ice.

Did you feel the trillions of neutrinos that just flew through your body? Probably not, because these subatomic particles rarely interact with matter. Neutrinos can travel through a lightyear's worth of lead without ever disturbing a single atom. Understanding these ghost-like particles could unlock mysteries of the universe, but how can scientists study neutrinos if they are seemingly undetecta DARPA, NGA transition novel optics technology to fieldable prototypes
