Space Saturday

Yep that time again….the old professor will force feed some news that has been missed….

Remember a few weeks ago Russia lost a rocket in a horrific explosion……some believe that it was an experiment in nuclear propulsion…..https://lobotero.com/2019/08/19/that-wayward-missile/

And that is the next fuel for space exploration….nukes.

Humanity’s next giant leap could be enabled by next-gen nuclear tech, NASA Administrator Jim Bridenstine said.

During the sixth meeting of the National Space Council (NSC) today (Aug. 20), the NASA chief lauded the potential of nuclear thermal propulsion, which would harness the heat thrown off by fission reactions to accelerate propellants such as hydrogen to tremendous speeds. 

Spacecraft powered by such engines could conceivably reach Mars in just three to four months — about half the time of the fastest possible trip in a vehicle with traditional chemical propulsion, said NSC panelist Rex Geveden, the president and CEO of BWX Technologies Inc.

Think back to the SciFi movies you have seen in the past…..wormholes were the preferred way to space travel…..well looks like scientist have a formula…..

Everybody wants a wormhole. I mean, who wants to bother traveling the long-and-slow routes throughout the universe, taking tens of thousands of years just to reach yet another boring star? Not when you can pop into the nearest wormhole opening, take a short stroll, and end up in some exotic far-flung corner of the universe. 

There’s a small technical difficulty, though: Wormholes, which are bends in space-time so extreme that a shortcut tunnel forms, are catastrophically unstable. As in, as soon as you send a single photon down the hole, it collapses faster than the speed of light.

But a recent paper, published to the preprint journal arXiv on July 29, has found a way to build an almost-steady wormhole, one that does collapse but slowly enough to send messages — and potentially even things — down it before it tears itself apart. All you need are a couple of black holes and a few infinitely long cosmic strings.

That is Saturday and I need a break…MoMo sez ….TTFN
