Jupiter Awaits Arrival of Juno

Spectacular VLT images of Jupiter presented just days before the arrival of the Juno spacecraft
In preparation for the imminent arrival of NASA’s Juno spacecraft, astronomers have used ESO’s Very Large Telescope to obtain spectacular new infrared images of Jupiter. They are part of a campaign to create high-resolution maps of the giant planet. These observations will inform the work to be undertaken by Juno over the coming months, helping astronomers to better understand the gas giant ahead of Juno’s close encounter.

Just a week until NASA's Juno spacecraft arrives in orbit around Jupiter, it's about to learn about the mission, the spacecraft and - of course - the science. I opened the link, examined the "press kit", and suddenly my coffee was cold.

Om en vecka ska Juno äntra sin eliptiska bana kring gasjätten Jupiter. Länken nedan innehåller samlad information, om och kring, hela uppdraget. Det är definitivt värt att sätta ett bokmärke för "presskittet".

Up for a Sunday longread? Check out the interactive press kit for NASA's Juno mission to Jupiter and its July 4th arrival in orbit.
Introduction. NASA's Juno spacecraft will arrive at Jupiter in 2016 to study our solar system's largest planet. From a unique polar orbit, Juno will repeatedly dive between the planet and its intense belts of charged particle radiation, coming only about 3000 miles (5000 kilometers) from the ...

Herschel deep-space telescope shuts down : The deep-space telescope Herschel has taken its final bow, climaxing a successful four-year mission to observe the birth of stars and galaxies. The largest and most powerful infrared telescope in space, Herschel made over 35,000 scientific observations and amassed more than 25,000 hours of science data, says the European Space Agency (ESA).

Launched in May 2009, Herschel carried 2,300 litres of liquid helium coolant, which evaporated over time. Its expected lifetime had been 3.5 years. At 7.5 metres high and four metres wide, Herschel had a launch mass of 3.4 tonnes. It carried three cameras and spectrometers and a primary mirror 3.5 metres across -- able to collect almost 20 times more light than any previous infrared space telescope.

The Roscosmos State Corporation for Space Activities (Russian: Государственная корпорация по космической деятельности "Роскосмос"), commonly known as Roscosmos (Russian: Роскосмос), is the governmental body responsible for the space science program of Russia and general aerospace research.

The Corporation was established on the basis of the now-defunct Federal Space Agency on December 28, 2015. Roscosmos was previously known as the Russian Aviation and Space Agency (Russian: Российское авиационно-космическое агентство, Rossiyskoe aviatsionno-kosmicheskoe agentstvo, commonly known as Rosaviakosmos).[2][3]

The headquarters of Roscosmos are located in Moscow, while the main Mission Control space center is located in the nearby city of Korolev. The Cosmonauts Training Centre (GCTC) is in Star City. The Launch facilities used are Baikonur Cosmodrome in Kazakhstan (with most launches taking place there, both manned and unmanned), and Vostochny Cosmodrome being built in the Russian Far East in Amur Oblast.

The current Director since January 2015 is Igor Komarov. In 2015 the Russian government merged Roscosmos with the United Rocket and Space Corporation, the re-nationalised Russian space industry, to create the Roscosmos State Corporation.

Festive-looking nearby planetary nebula
Astronomers using NASA's Hubble Space Telescope have photographed a festive-looking nearby planetary nebula called NGC 5189. The intricate structure of this bright gaseous nebula resembles a glass-blown holiday ornament with a glowing ribbon entwined.
 
Planetary nebulae represent the final brief stage in the life of a medium-sized star like our Sun. While consuming the last of the fuel in its core, the dying star expels a large portion of its outer envelope. This material then becomes heated by the radiation from the stellar remnant and radiates, producing glowing clouds of gas that can show complex structures, as the ejection of mass from the star is uneven in both time and direction.
 
A spectacular example of this beautiful complexity is seen in the bluish lobes of NGC 5189. Most of the nebula is knotty and filamentary in its structure. As a result of the mass-loss process, the planetary nebula has been created with two nested structures, tilted with respect to each other, that expand away from the center in different directions.
 
This double bipolar or quadrupolar structure could be explained by the presence of a binary companion orbiting the central star and influencing the pattern of mass ejection during its nebula-producing death throes. The remnant of the central star, having lost much of its mass, now lives its final days as a white dwarf. However, there is no visual candidate for the possible companion.
 
The bright golden ring that twists and tilts through the image is made up of a large collection of radial filaments and cometary knots. These are usually formed by the combined action of photo-ionizing radiation and stellar winds.
 
This image was taken with Hubble's Wide Field Camera 3 on July 6, 2012, in filters tuned to the specific colors of fluorescing sulfur, hydrogen, and oxygen atoms. Broad filters in the visible and near-infrared were used to capture the star colors.

Solar Storms hit Jupiter
Solar storms are triggering X-ray auroras on Jupiter that are about eight times brighter than normal over a large area of the planet and hundreds of times more energetic than Earth’s "northern lights," according to a new study using data from NASA’s Chandra X-ray Observatory. This result is the first time that Jupiter's auroras have been studied in X-ray light when a giant solar storm arrived at the planet.

Solar Storms hit Jupiter
Solar storms are triggering X-ray auroras on Jupiter that are about eight times brighter than normal over a large area of the planet and hundreds of times more energetic than Earth’s "northern lights," according to a new study using data from NASA’s Chandra X-ray Observatory. This result is the first time that Jupiter's auroras have been studied in X-ray light when a giant solar storm arrived at the planet.

The Sun constantly ejects streams of particles into space in the solar wind. Sometimes, giant storms, known as coronal mass ejections (CMEs), erupt and the winds become much stronger.
This new study found that the interaction at the boundary triggers the X-rays in Jupiter's auroras, which cover an area bigger than the surface of the Earth.

These composite images show Jupiter and its aurora during and after a CME's arrival at Jupiter in October 2011. In these images, X-ray data from Chandra (purple) have been overlaid on an optical image from the Hubble Space Telescope.

The left-hand panel reveals the X-ray activity when the CME reached Jupiter, and the right-hand side is the view two days later after the CME subsided. The impact of the CME on Jupiter's aurora was tracked by monitoring the X-rays emitted during two 11-hour observations.
The scientists used that data to pinpoint the source of the X-ray activity and identify areas to investigate further at different time points. They plan to find out how the X-rays form by collecting data on Jupiter's magnetic field, magnetosphere and aurora using Chandra and ESA’s XMM-Newton.

A paper describing these results appeared in the March 22, 2016 issue of the Journal of Geophysical Research. The authors on the paper are William Dunn (UCL), Graziella Branduardi-Raymont (UCL), Ronald Elsner (NASA's Marshall Space Flight Center), Marissa Vogt (Boston University), Laurent Lamy (University of Paris Diderot), Peter Ford (Massachusetts Institute of Technology), Andrew Coates (UCL), Randall Gladstone (Southwest Research Institute), Caitriona Jackman (University of Southampton), Jonathan Nichols (University of Leicester), Jonathan Rae (UCL), Ali Varsani (UCL), Tomoki Kimura (JAXA), Kenneth Hansen (University of Michigan), and Jamie Jasinski (UCL).

International Space Station. 
The ISS serves as a microgravity and  Space environment research laboratory in which crew members conduct experiments in biology, human biology, physic, astronomy, meteorology, and The other fields.  station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars. The ISS,  maintains an orbit with an altitude of between 330 and 435 km (205 and 270 mi) by means of reboost manoeuvres using the engines of the  Zevzda module, or visiting spacecraft. It completes 15.54 orbits per day.
ISS is the ninth space station to be inhabited by crews, following the Soviet and later Russian Salyut, Almaz,  and  Mir stations as well as Skylab from the US. The station has been continuously occupied for 15 years and 164 days since the arrival of Expedition 1 on 2 November 2000. This is the longest continuous human presence in space, having surpassed the previous record of 9 years and 357 days held by Mir. The station is serviced by a variety of visiting spacecraft: the Space Shuttle, Soyuz, Progress, the Automated Transfer Vehicle,  the H-II  Transfer Vehicle, Dragon, and Cygnus. It has been visited by astronauts, cosmonauts and space tourists from 17 different nations.
