Triggered by the impact of a coronal mass ejection on New Year’s eve, a moderate geomagnetic storm brought a celebration of sky lights to planet Earth’s high latitudes yesterday. In this New Year’s nightscape, the shimmering reddish curtains ofaurora australis along a southern horizon are captured over Morgiana, SW Victoria, Australia. Of course, more permanent jewels of the southern skies are on the scene. The southern Milky Way, Alpha and Beta Centauri, and bright stars of the Southern Cross are on the left. In silhouette, branches of the large foreground tree stretch across the Milky Way’s satellite galaxies, the Large and Small Magellanic clouds. The bright star framed near the tips of tree branches at right is Achernar. Alpha star of the constellation Eridanus, Achernar is sometimes known as the southern end of the river.

Ion thrusters (for a future post)

An ion thruster is a form of electric propulsion used for spacecraft propulsion that creates thrust by accelerating ions with electricity. The term is strictly used to refer to griddedelectrostatic ion thrusters, but may often more loosely be applied to all electric propulsion systems that accelerate plasma, since plasma consists of many ions.

Ion thrusters are categorized by how they accelerate the ions, using either electrostaticor electromagnetic forces. (Using opposite charges to accelerate ions away from each other, or magnets to suck them out the back, can be used with PLASMA, as plasma strip away it’s electrons, creating a positive charge)

This is just some explaining for my next post 🙂 #space#rocket #nasa #sls #orbit #rocketscience #facts #deepspace #cosmos #ion #physics #chemistry by astro.dylan
