Astronomy and space exploration

yeah I'm sceptical about those claims as well, works with spectrography, a lot of the readings are just gonna be in borderline noise. look at what we know (or dont know) about bodies atmosphere in our own solar system
 
I totally agree with that. It's clear that we need more accuracy. I only wonder if there's this small true possibility to get additional data with what we already have.

But I guess this question will be futile once we have better technology... which is coming.
 
Yeah its like we know how the universe worked after the first 16 nanoseconds (i.e. before that no we dont, but trust us we know after those 15 nanoseconds) whats that? yes true theres 80% of the universe we still can't account for but trust us we know how it works after the first 14 nanoseconds.
Don't know about you but I'm a little bit doubtful about the accuracy of those claims (make me sound like a trump supporter)
What I would love to see being down is returning to the moon, stick some fucken big telescope/s on the dark side of the moon

There are several Moon missions which goal is to establish a human base there. I think that will happen sooner than later.
 
yeah setting up a moo base an mining fuel for deeper trips should be the first priority (prolly at one of the poles)
how much fuel/payload ratio to get off earth, heaps, i.e. most is just wastage Contrast that with from the moon we've all seen those tiny moon landers, yet they were enuf to descend to the moon, and then reascend to moon orbit

I'ld love to see how far they got off the ground on earth if they tried to launch with that thing

Basically what needs to happen is for china to go to the moon (and they will prolly sooner than we think), perhaps that'll wake up the west
 
A Nuclear Reactor for Space Missions Passes Final Major Ground Tests

Scientists, engineers and reporters gathered at NASA's Glenn Research Center in Cleveland on May 2 for a news conference announcing the latest results of the Kilopower nuclear power plant project: It has finished all of its major ground tests and met or surpassed the development team's expectations.

NASA is developing the experimental reactor to provide reliable energy for long-duration crewed missions to the moon, Mars and destinations beyond.​

But...
We Now Have A Working Nuclear Reactor for Other Planets — But No Plan For Its Waste
...
When that happens, the uranium core will have to be stored somewhere safe; spent reactor fuel is still dangerously radioactive, and releases lots of heat. On Earth, most spent fuel rods stored in pools of water that keep the rods cool, preventing them from catching fire and blocking radiating radioactivity. But on another planet, we’d need any available water to, you know, keep humans alive.​

Just listened to the 2nd to last latest ted radio hour (apr 27th)
some guy was saying the moon landing was about the last great thing humanity has done (I suppose internet would qualify, though thats nebulous) so many goals we could of aimed for but we havent, a bit lame. look at that ship above its the most amazing thing, yeah we're gonna shot that small payload craft to the moon land it safely on it, and then blast the top half up and come back to earth with the humans intact, Fucking madness, totally unbelievable but they done it. Going to mars now with todays tech is literally an order of magniutde easier thats why ..... we havent done it

Launch of Mars InSight: :)


Some info about the mission:
https://www.space.com/40468-insight-mars-lander-surprising-facts.html

And now some info about the minisatellites:
NASA's Mars Cubesats 'Wall-E' and 'Eva' Will Be First at Another Planet
When NASA's InSight Mars lander launches for the Red Planet on Saturday (May 5), it won't be traveling alone. Two small spacecraft, nicknamed "Wall-E" and "Eva," are hitching a ride as the first cubesats to visit another planet.

The twin cubesats are tiny spacecraft of a type whose design became popular in the 2000s as miniaturized computers increased the craft's capabilities. While they don't have all the backup systems and capabilities of bigger spacecraft, cubesats are useful for applications such as communications, tracking shipping or performing Earth observation. Until now, all of them stayed close to our home planet.​

true though I'ld say thats more of an improvement of past particle colliders and not really so exceptional like the moon landing was, OTOH the ligo stuff is new

Yeah was a great time for space exploration putting humans into space context, but then look at the budget each project had and importantly the difference in health and safety vs risk then to now (the low point would had been some of the shuttle related projects that I think came back to cost and culture shift at NASA).

Does raise when one can expect another lunar landing or deep space (still far from simple) with astronauts.
I would say though Voyager probe and shuttles are up there from an engineering perspective as great space related feats.

One quote that is very applicable and I will always remember is that from John Glenn and used for comedy/satire effect in Armageddon (not exactly same but context comparable):
John Glenn said:
"“As I hurtled through space, one thought kept crossing my mind - every part of this rocket was supplied by the lowest bidder.”

I read this article a few days ago:
Could Alien Life Cling Beneath the Icy Ceilings of Frigid Ocean Moons?

aHR0cDovL3d3dy5zcGFjZS5jb20vaW1hZ2VzL2kvMDAwLzA3Ni8wNDQvb3JpZ2luYWwvMTQwMjQ3X3dlYi5qcGc=

Europa's surface is a shell of ice covering a global ocean and displaying amazing features. Long, linear cracks and ridges crisscross the surface, broken by regions of disrupted terrain where the crust of surface ice has cracked and refrozen into new patterns.​

And then yesterday I saw some new articles about Europa, confirming the existence of plumes:
Water plumes on Jupiter's moon Europa?
Old data reveal new evidence

Scientists re-examining data from an old mission bring new insights to the tantalizing question of whether Jupiter's moon Europa has the ingredients to support life. The data provide independent evidence that the moon's subsurface liquid water reservoir may be venting plumes of water vapor above its icy shell.

Space Warp Dynamics
---Update: May 21, 2018---
Our paper has been revised and submitted to the AIAA. We will be updating the paper on our website with the new one. The new paper is in a scientific publication format, but contains all the same information. We have spent a great amount of time revising the paper and getting input from multiple reviewers. As a result, production of Model 16 has been delayed. Now that we are done with tiresome paper revisions we will head back to the lab and finish up Model 16. It should be ready for testing in about two weeks. Now that progress on the new motor has been made, all testing on model 15 has been discontinued.

NASA’S NEW VASIMR PLASMA ENGINE COULD REACH MARS IN LESS THAN 6 WEEKS

NASA recently delivered $10 million in funding to Ad Astra Rocket Company of Texas for further development of its Variable Specific Impulse Magnetoplasma Rocket (VASIMR), an electromagnetic thruster proficient of propelling a spaceship to Mars in just 39 days. NASA’s funding was part of the “12 Next Space Technologies for Exploration Partnership.” Ad Astra’s rocket will travel ten times quicker than today’s chemical rockets while using one-tenth the amount of fuel.​
