BREAKING: InSight won't launch in March due to a problem with a CNES-built instrument. Launch will be delayed at least 26 months! : space

Both good and bad news, yay!

awesome!!!!!!!!  more 238 is a dam good thing.. lol  was getting a bit worried with stockpiles getting so low.  reusable rockets and this in one week,   get news for the future

and i heard about Insight yesterday,  sucks..  but atleast they found a problem now instead of after launch lol

Elon Musk says the Falcon 9 rocket SpaceX successfully landed is 'ready to fire again' | The Verge

AMAZING!



Their plan is to dry test the rocket again just to see how it performs, and then ship it off to a museum.

Awesome! I figured  theey would have to refurb it lol it being ready to go is like a dream.

In similar news, North Korea tested a hydrogen bomb the other day.

Ive been reading about this.  A few people are suggesting that it's propaganda.  

The hydrogen bomb would have been much smaller than anything prior.  A physics professor Richard Miller was suggesting that it was a boosted fission bomb rather than a hydrogen one.  

The size of the explosion, yielding a 5.1 magnitude earthquake, is roughly what you would get from a 10 kiloton bomb, half of the energy release of the first US pure fission bomb exploded in New Mexico. So they are still producing duds.  The first three US fission bombs were not boosted, and they released considerably more energy than did this North Korean test.
Nonetheless, I suspect that the engineers and physicists responsible for this bomb told Kim Jong Un that they had successfully exploded a hydrogen bomb. It was their quickest way to be able to claim "hydrogen" -- by assembling a boosted fission bomb.
Moreover, I suspect the bomb was even smaller than 10 kilotons. It is in the North Korean interest to try to exaggerate the size of the blast. If I were given the job of doing that, I would do it by increasing the coupling between the explosion and the rock. (If you are trying to hide a bomb, you decrease that coupling.) The goal would be to transfer more energy to the rock, thereby fooling the seismic people into thinking that a bigger bomb was exploded. Increasing that coupling is technically far far easier than making a bigger bomb, so I assume that's what they did. That means that their "hydrogen bomb" might have been only a few kilotons, maybe 1/10 the size of the first WWII US weapons.

I think it was more of an atom bomb with hydrogen inside.

Anyways, I just find it to be just another one of North Korea's routine "Hey, you nitwits! Pay attention to us!" to the US and South Korea.

People are really scientifically illiterate....

Someone just posted on facebook about testing light bulbs for radiation.  They only tested the CFL bulbs, and they started complaining that it was giving off radiation.... 

Well, visible light is a form of radiation...
