URANUS' MAGNETOSPHERE OPENS & CLOSES
-
Newly analyzed data from Voyager shows that the magnetosphere is ‘open’ in one orientation, allowing solar wind to flow into the magnetosphere; it later closes, forming a shield against the solar wind and deflecting it away from the planet. -

Magnetic tempest 🔥 Supercomputer simulation of turbulence in the magnetosphere, the magnetic shield layer that protects Earth from solar wind.
.
"During solar storms, the intensity of energetic particles in the solar wind can increase dramatically, wreaking havoc on Earth's technological systems. This so-called space weather has caused over $4 billion in satellite losses alone. Spacecraft observations have revealed that many regions in the magnetosphere exhibit turbulence, which can enhance mixing–just as we mix cream into coffee by stirring it... We provided our simulation data to a team of engineers at NASA Goddard Space Flight Center who are using it in the design and planning of NASA's upcoming Magnetospheric Multiscale Mission (MMS). The primary goal of MMS is to detect and make detailed measurements of the electron-scale features in the magnetosphere that are thought to have global consequences"

⭕ An aurora, sometimes referred to as a polar lights or northern lights, is a natural light display in the sky, predominantly seen in the high latitude (Arctic and Antarctic) regions. Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere) due to Earth's magnetic field, where their energy is lost. The resulting ionization and excitation of atmospheric constituents emits light of varying color and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes.

#throwback post! Fifty years ago this weekend, in 1966, the #Esrange sounding rocket range and research centre was inaugurated. Located outside the town of #Kiruna in northern #Sweden, Esrange was built in 1964 by ESRO, the European Space Research Organisation, forerunner of ESA. The first #rocket launch from Esrange occurred on 19 November 1966.
152 sounding rockets were launched from Esrange between 1966 and 1972: 72 under ESRO's direction and 80 within national programmes. Most flew during auroral activity to study the effects of energetic electrons and ions that had been accelerated in the distant #magnetosphere before precipitating along magnetic field lines in the auroral #atmosphere. The programme came to an abrupt end in 1972 as part of the preparations for the creation and expansion of ESA, and ownership was transferred to the then newly created SSC - Swedish Space Corporation.

The Sun: Sprawling Coronal Hole | NASA SDO
A large coronal hole stands out as the most obvious feature on the sun this week (Oct. 12-13, 2017). The dark structure, shaped kind of like the Pi symbol, spreads across much of the top of the sun. Though one cannot tell from this video clip in false-color extreme ultraviolet light, it is spewing high-speed solar wind particles into space and has been doing this all week. It is likely that these charged particles have been interacting with Earth's atmosphere and generating many aurora displays in regions near the poles the past several days.

INTERVIEW: The Greeks who participated in the #Cassini spacecraft mission
・・・
On September 15 2017, NASA’s Cassini spacecraft will complete its remarkable story of #exploration with an intentional plunge into #Saturn’s atmosphere, ending its mission after nearly 20 years in space. Among the #researchers, who have been involved in analyzing the valuable data provided by Cassini, are several #Greek scientists.
The Greek scientists participated in various stages of the #mission. Some of them are already in USA, where they are invited to attend the NASA’s JPL in #Pasadena, #California, to see the endof the Cassini mission, such as Mr Krimigis and Ms Coustenis.
Launched in 1997, Cassini arrived in orbit around Saturn in 2004 on a mission to study the giant #planet, its #rings, #moons and #magnetosphere. In April of this year, Cassini began the final phase of its mission, called its Grand Finale, a daring series of 22 weekly dives between the planet and its rings. On Sept. 15, Cassini will plunge into Saturn, sending new and unique science about the planet’s upper atmosphere to the very end. After losing contact with Earth, the #spacecraft will burn up like a meteor. This is the first time a spacecraft has explored this unique region of Saturn, a dramatic caonclusion to a mission that has revealed so much about the ringed planet.
Ellines.com contacted the Greek scientists who participated and they shared with us their thoughts on the Grand Finale of the Cassini mission.
