First Imagery from GOES-17 
  
On March 1, 2018, NASA and NOAA successfully launched GOES-17, the second in a new series of four highly advanced geostationary weather satellites. Once positioned in its final orbit, the satellite will be renamed GOES-West and provide coverage of the American continent and much of the Pacific Ocean. 
  
This short sequence contains the first images captured by the Advanced Baseline Imager (ABI) on board the satellite. It combines imagery from two visible and one infra-red spectral bands to form a 'GeoColor' composite. The new generation of GOES is capable of viewing the Earth across 16 spectral bands and provides 4x the spatial resolution and more than 5x faster coverage than its predecessor. 
  
Unfortunately, the ABI on GOES-17 encountered cooling issues after deployment that severely impairs the performance of 13 near-infrared and infrared spectral bands. It's unclear what caused the issue and whether it can be resolved. 
  




Capturing Plasma in a Syringe 
  
The Tesla Coil is an electrical circuit invented by Nikola Tesla in 1891 that is used to produce high-voltage, low-current electricity. They are best known for brilliant sparking discharges caused by ionization of the surrounding air by the strong electric field, which allows it to conduct electricity. Ionized gases are also known as plasma, the fourth fundamental state of matter. 
  
Here, a syringe is being used to create a near-vacuum environment that allows the electrons to travel more easily and further than under standard atmospheric conditions. This allows the plasma to persist for much longer than normal.
