Supermoon ,moonrise. sunset and moon halo- 2017-Dec-3 and 4

Although  I don't care too much about supermoons, I always like to see the full moon rising and this evening just 17 minutes after sunset I had a chance to see and take some photos.

The next photos clearly show why I can't see the exact moon rise. There ar mountains to the east which blocks the horizon. It requires about 60 minutes driving to pass them (not including evening traffic jams!)

A nice surprise was an airplane which was considering enough to cross the moon.

And in the video notice how the hot gases from the engines twist the photo


Here is the full movie of the moonrise at 4x speed


High clouds continued the following evening so I took some other fine photos:

  • Xcor was making a suborbital reusable launch vehicle (a suborbital spaceplane). XCOR filed for Chapter 7 bankruptcy Wednesday in the Eastern District of California.
  • NASA is providing an update on the first integrated launch of the Space Launch System (SLS) rocket and Orion spacecraft after completing a comprehensive review of the launch schedule. The new launch date for an unmanned first flight of the Space Launch System is Dec, 2019. This is NASA’s stretch goal target rather than June 2020 which is what the review expects will happen
  • An explosion occurred on Saturday, Nov 4, 2017 during a test of a “Block 5” Merlin engine, which will be used in a future generation of the company’s Falcon 9 rockets.
    It was a engine qualification test and no one was injured.
    The block 5 Falcon 9 will have higher thrust on all of the engines and improvements on landing legs compared to the block 4 Falcon 9 Full Thrust. There are also a number of small changes to streamline recovery and re-usability of first-stage boosters. Alterations to the launch vehicle are primarily focused on increasing the speed of production and efficiency of re-usability. SpaceX aims to fly each Block 5 first stage ten times with only inspections in between, and up to 100 times with refurbishment.

  • "Rocket Lab" broke new ground today when its Electron rocket reached space at 16:23 NZST. "Rocket Lab" has said they will charge $5 million for each rocket. The SpaceX Falcon 9 has a launch cost of $57 million. "Rocket Lab" will launch up to 225 kilograms. The Falcon 9 can launch 22800 kilograms to low Earth orbit. "Rocket Lab" 3D prints almost all of parts. They use carbon composite materials for many parts which are lighter. "Rocket Lab" uses advanced batteries to enable electric turbopumps.
