No truer words can ever be spoken. The depths of the mind are indeed complex but not tangible. Our oceans floors hold many secrets about life and the history of our planet. Space is, for all intensive purposes, infinite. This isn’t technically true, to our knowledge. We estimate the true size of the Universe to be 93 Billion Light Years. So vast, in fact, that light from one side will never reach the other. This is why it is the pinnacle of exploration.
Eventually, one day, our destiny will lie somewhere in space. Perhaps another planetary body in this solar system or even another star system. That is, if we don’t blow ourselves up or suffer a cataclysmic set back.
The recent White House budget leaves me both concerned and yet I see an opportunity to be optimistic. I’ve been reading forums to get people’s takes on this. Mind you this is coming from people who work in the industry to plain people like myself. It is inevitable that politics gets head-firsted into the mix. I made that slang up. Nice eh? I guess there is no way around it but the degree of “This was Bush’s fault!”; “This was Griffin’s fault”; “Obama sux!” is just a little much.
I try my damnedest to take a middle road approach. I want science. I want exploration. I want a manned flight program (also termed HSF for Human Space Flight). At the moment we have it with Shuttle. In a few short months, it will be done and gone. What happens after that? We’re grounded, at least humans are.
Private companies are really getting into the mix of things which does excite me. Thing is, they’re a ways off from manned flight. It will happen, just not quite soon as we’d like.
Constellation is dead. I’m sad and yet I can understand this move. Some claim to have had the insight or ESP enough to know it was doomed from day one. I think having a pessimistic attitude isn’t very healthy. I don’t work in the industry, I follow it from a few rows back. I can say that my interest is important, not as a single entity but gathered with the combined interest of persons just like myself. Lack of public interest will kill a program deader than dead. Apollo anyone?
So, I thought about the cancellation of that program and realized, ok, maybe this isn’t as bad as it seems. I’m still icky feeling about not having the ability to put humans up but lets think this out. The downfall of Constellation was reaching back to the past to sort of re-use older technologies or at least model from them. What we need are newer technologies that are laced with our learnings of the past.
I think the biggest technological advance we need is in propulsion. Chemical rockets are dandy at getting heavy vehicles off the ground and into space but once in space you need something else. Something that’s less cumbersome, less prone to failure and has some oomph! These technologies should be researched to make Moon and Mars missions faster. Transit time to Mars is MONTHS. With new propulsion you could get it down to weeks; or so I’ve heard.
So, new technologies and private companies. I think I actually like the sound of that. Will they deliver? The talk is there, the walk is yet to come.
More notes on the budget are promised robotics and planetary missions. This is very exciting to me. Rovers are great tools for science! Just look at Spirit and Opportunity; they vastly outlived their planned mission time. If we had a mission going up every other month, I’d be stoked.
A final note about canceling the Moon program. Listen, we’ve been there before. Yes, actual people walked on the actual Moon. That program was initially a race; a race we would win. After that, you had a group of giddy scientists drooling over the prospect of getting some precious samples back. That came later and Apollo XVII was the final Moon-shot. We never spent more than a couple of days there. When we go back, we need to plan on STAYING for a length of time. Weeks, not days.
China wants to go there. Let them go, plant their flag and then come back. It’s a great thing for a country. I’d applaud them for it. As the saying goes “been there, done that”. It’s time we went a step ahead. That way when countries are landing and planting their flags, we can wave at them from our cozy Moon habitats. From that point we can build on and then eyeball Mars or even asteroids.
So, finally, it’s bittersweet for me. I wanted to see Constellation work but ultimately I want to see anything work. I’ll hold on the promise of some serious R&D and science missions. I’ll hold on to private companies keeping us in orbit too. It’s a big time shake up of things. Perhaps it was needed.
Obama says we need to get young people into science and math. I couldn’t agree more. If he truly means this then he needs to deliver on this budget. NASA has inspired generations of people. Let’s keep it that way.
If this flops as a dud and our space program is left floundering for years, I’ll be one mad space cadet. >:o
(PhysOrg.com) — Astronomers have long known that in many surveys of the very distant Universe, a large fraction of the total intrinsic light was not being observed. Now, thanks to an extremely deep survey using two of the four giant 8.2-metre telescopes that make up ESO’s Very Large Telescope (VLT) and a unique custom-built filter, astronomers have determined that a large fraction of galaxies whose light took 10 billion years to reach us have gone undiscovered. The survey also helped uncover some of the faintest galaxies ever found at this early stage of the Universe.
Though, I do have my own theory as to where they looked…
This is a very clever little bit of flash put together by someone whom I have no idea who they are. All I know is that the site was blocked at work. I went in and nabbed the SWF file and I’m going to place it on my blog. You still have to endure the Newgrounds logo to see the animation.

Use the keyboard to move left or right for a smoother experience. The largest things in the Universe are mind boggling. The really fascinating stuff is all of the tiny things that go into making the world around us. You can see how small a neutrino is for instance; and why it passes unhindered through just about everything (including entire planets!).
The music is very pleasant too. 🙂
