For those of like minds.....retirement of the Hubble and rise of the James Webb.
http://jwst.nasa.gov/index.html
Clicking on the 'About The Webb' tells us it's scheduled for launch in October 2018.
My current goal in this short life is to stay ornery and live long enough to witness this launch and treat my orbital photon receptors to take in even more detailed cosmic eye candy.
I recall the Hubble launch (and the fix necessary...ouch for NASA) with clarity.
It's deep field image, confirmation of the acceleration of the universe's expansion to name a couple of Hubble's discoveries.
Twenty five years in service is an outstanding legacy for that old bird.

Took physics in HS and loved it. Much more interesting than just math. Also, took astronomy in college for two semesters. Really cool stuff. Black holes were just a theory back then, and now there is just about proof that they exist.
Very recently I read that they (someone) found the furthest galaxy, ever, that is 13.1 billion light years away. Not just 13.1 million miles. A light year equals ~5.6 trillion miles. That's really far. What is more interesting is that we see something like that as it was 13.1 billion light years ago. No telling what t looks like right now, unless we travel there, which for now is impossible.
Did anyone read that NASA is working literally on traveling faster than the speed of light? They gave an example if we had a ship that could use this type of propulsion, you could travel to Mars in 30 days. Here is the reference: http://www.space.com/26713-impossibl...nasa-test.htmlHelping one person may not change the world, but it could change the world for one person.

I like archaeology, too. Would have made for a really cool career.

I believe the reference I am referring to is not the speed of light, but nevertheless extremely fast. So fast as to get to Mars in about 30 days or so.
The reference again: Here is the reference: http://www.space.com/26713-impossibl...nasa-test.html
Has to do with space-time-continuum. Very interesting and theoretically possible.Helping one person may not change the world, but it could change the world for one person.

Reveille everyone...
Yes...that Nova program (1 and 2) is still on my DVR for viewing again.
Along with that NOVA series on 2/18/15 I watched and DVR'ed 'Petra: The Lost City Of Stone'....good watch I might add.
MarkIT....
My current opinion...I don't think us puny humans will ever be able to surpass the SOL.
But, it seems to me being able to bend space would be a more valid approach to long distance space travel.
Ha...yes....'5.6 trillion miles' is 'really far'.
Whatevergirl....
I also love archeology....maybe you can catch the 'Petra' story I note above sometime.
DocHoss....
Yep...the expansion is fact and the surprise was the expansion was accelerating (red shift) which IIRC was confirmed back in '96.
Thanks for keeping this one alive and kicking.

That 30 days or so can be down with Ion Thrusters that NASA is already using. A major limitation on the speed is the force that a human body can withstand. If you want the humans to survive the trip would be around 39 days. The spacecraft would spend half the trip in positive acceleration and the second half negative.

For you rock lickers (or *us* rock lickers, I should say) there's a great article posted on Ars Technica about the rise and rise of the Sierra Nevada Mountains. The Ars resident science writer has been putting together some superb material lately.
And for those of you wanting to expand our minds further than the solar system, I was looking for a link to http://www.centauri-dreams.org/. It's a blog that is truly thought-inspiring.“Those who can make you believe absurdities, can make you commit atrocities.”

Somehow I had a daft moment and didn't catch this post.
Absolutely....too bad no one is willing to pay me a living wage, carry a pack of archaeo goodies and turn me loose with my paint brush and ice pick to gently reveal ancient history.
I did have the very timely opportunity in 1971 (college geology class) to be involved in the excavation site of an Ohlone Indian burial site in Los Altos Hills, Ca..
I did uncover a skull and partial shoulder area.....loved the experience.
Regarding that site your suggest: I click 'next' and even tried the little arrow at right of the first image and the page does not advance.
I don't have a clue as to why but will try again later.
Thanks for the link....back to it.Last edited by Wayne Evans; 05-21-2015 at 11:46 AM.

neat post, I recalled that part of physical science on mass and gravitational pull.
I got caught up trying to make little orbits around a red planet.I'm open to any suggestions and have a difficult time accepting limitations without an honest effort on my part, you can count on that!

Watched this the other day on TV, but saw youtube had it uploaded a few months ago.
Extremely well preserved, 40k yr old mammoth, being autopsied and a South Korean lab working on getting complete strands of dna for cloning.
Blood came pouring out as they hacked into it in the permafrost, and the trunk they dissect looks like it was from an animal that
died yesterday.

DocHoss.....
I saw that yesterday too.
Pretty cool surprise for all those that built and launched it.
That sort of thing is great for us sci-'geeks'.
(Of course, I liked your Pi joke too. )
Steff099...
Ohhhh yeah....'Blood came pouring out as they hacked into it in the permafrost'.
Fascinating find and something (the Mammoth cloning) I've thought deeply about for some time.
I guess we'll have to continue waiting for subsequent surprises.
Thanks for commenting.....back at it.USMC: 1965-1969

Love this thread. I have subscribed to a NASA publication called NASA Tech Briefs for over twenty years. I can't tell you how many times I've read about some research project that NASA funded that ends up in the private sector here on Earth helping people. The best part? The magazine is FREE!!

Feliz Viernes....
First....
I'm extremely intrigued by Kepler's latest find being Kepler-186f.
Of course, we still don't know enough yet but the basic criteria for any sort of bio-life seems could actually be present according to the current banter.

Second....
New Horizons is beginning to send back images of Pluto.
The fact it has any sort of atmosphere is a total surprise (cosmologists have know for some time) to me.

Be safe on this Friday eve and do carry on....
