Weird answers you're getting. "No, but it will be tiny" - well is it or is it not?! Yes, it will alter its trajectory, but the effect will be very small. Gaining or losing speed depends on the angle of arrival. Hydrogen is lightweight so it's easily blown away by the savage young Sun even that far away, but I'd say that most of it simply reacted with other stuff over the eons. Nitrogen is, unlike hydrogen, almost inert in all those conditions.

For all we know, the probe might be spinning debris right now.
-
I've managed to grab this manually. At the exact zero time.

Have you experienced the annoyance with that hype thread? When you can't even click to get to the last post from all the crap raining down? My bet would be that it's scanning the outer parts of the atmosphere.
-
Please don't turn this thread into immature "hype train" one. People are posting latest important information here so don't drown it with tons of infantile posts.
-
That image, where is it from? I can't find it on JPL or anywhere! Stunning!
-
One hour, a bit over 50000 km to go.
-
All this "Pluto is bigger" ... It's not like it was 500 km larger. We're talking about statistical errors and predictions. It is still possible Pluto is not the largest known, and definitively possible not the largest Kuiper belt object out there. Thousands of very similar objects are waiting to be discovered. It's like an asteroid belt, but icy. And no, it will not be a planet. Nothing this mission offers will change it and that's for the best.
-
NH has just turned around and LORRI is up. Pluto now barely fits into its field of view. The photos it's taking right now will be very high quality compared to the latest we have now. Hype!

Black and white cameras are not old and obsolete. If I ever become loaded with money, I'm gonna buy a monochrome camera. It's because a monochrome camera gives much more sensor density. If you have a regular digital color camera, this is how its sensor works. Basically you have a third of your sensor used for every color channel. With monochrome, you can have very dense packed image data, and if you want color images, you put a filter over the camera that absorbs everything but the band you want (for example you put a 523 nm transmissive, and rest of the spectrum restrictive) and you get that channel. With three channels like typical primary red, primary green and primary blue, a computer can synthetize a color RGB image and display it over a monitor for us to see. Sometimes probes don't have R, G and B filters. They might have near infrared band pass filter, orange filter and soft ultraviolet one. Those can also be fed to the software, telling it to synthetize a RGB image using those channels. The resulting image does not have true colors. It has approximation of true color which is usually good enough. I've done lots of such experiments over the years. Just recently I did two images using several filters for a RGB model. This one used, if I recall correctly, near infrared, green and very deep and quite narrow blue band. This one used something close to primary colors. Still a bit off.

What is the definition of life?
lajoswinkler replied to RAINCRAFTER's topic in Science & Spaceflight
Yes, it's not simple and certainly not yes or no, but by the basic definition of a system resisting dispersal, viruses are not. The only thing that resists (total) dispersion is the data they carry. That's completely different thing and can't be lumped into the same category. -
Again and again, you're showing that you don't know how science works. No, I can not prove a negative. I can only acquire evidence to support a positive claim, something you can't do and I can. Living in, and forming in, those are two incredibly different things. I could imagine simple cells being suspended in percolating parts of the atmosphere of a planet where significant mist is found, but unless the nutrient influx and reproduction rate aren't high enough, critters would get eaten by the planet as they would gradually all fall down. But for something to form in such environment, that's a straight no. As I've said, there are no phase boundaries in gas giants. The atmosphere just goes thicker and hotter, and gas giants are, by that criteria, a lot worse hell than Venus is. It quickly goes too hot for any remotely complex molecules to exist. It's not like with Earth oceans which have upwelling of nutrient rich stuff that's consumed by plankton. Anything going up from Jupiter's depths would be deprived of chemical energy, broken to the elements which would, upon cooling, spontaneously form simplest compounds.

What is the definition of life?
lajoswinkler replied to RAINCRAFTER's topic in Science & Spaceflight
Fire does not apply, neither do saturated solutions which evaporate and deposit crystals. The only people I've ever heard considering such things living are philosophers and people studying the humanities. When one doesn't know natural science, one can not present explanations pertaining to the universe. It's like those monks debating about the number of teeth in horse's mouth. One needs to open the horse's mouth and count the bastards. The most important property of a living organism is that it's an ordered pile of matter that is resisting dispersion into disorder by creating localized order at the expense of increasing much more environmental disorder. Fire does not do that, and neither do crystalizing solutions. Watch this and things will be a lot more clear. Viruses don't do it, either. They're not alive by the basic definition. Also, life and living organism are not synonims. Life is a much broader term. -
Told you so, there's a polar cap on Pluto. I was right. We don't know that because the data on Eris has nowhere near the precision available for Pluto.
-
I don't know about you, but one part of Pluto reminds me of The Oatmeal goofy faces.
-
There is no surface on Jupiter. If you mean by surface of clouds, check these two graphs. First one is less detailed, second one focuses on the cloud layer.
-
Thing is, it's not the first time same people are beating this dead horse. There are certain individuals here who like to push their wishful thinking as scientific theories, so people get tired of writing the same things all over again. Astrobiology is something I endorse and I really don't talk out of my ass. These are the basics. Basics of chemical reactions. In gas phases it's physically impossible to have organized systems clumped up together, forming boundaries with equilibriums and solvated particles crawling around through the crowd.
-
No, there are tiny solid crystals way up high in the atmosphere. Ammonium sulfide, ammonia, hydrogen sulfide, three dominant compounds in shifting equilibrium, both in the sense of chemical reaction and phase change from gas to solid. There are other compounds, too, but these three are most obvious. Down below hydrogen and helium are getting more and more dense and hot, gradually turning from gas to supercritical fluid. No phase boundary. Jupiter goes incredibly hot incredibly fast in its depths, so we can't expect anything complex coming up from its depths, if it comes at all. You throw a probe built like a batysphere, encased in a tough reentry shield, into the planet. It slows down (incredible, enormous decelleration), deploys a parachute and takes measurements as it falls down. If you knew anything about these things, you'd never stick to the classical ignorant "life as we know it". It's not about biology. It's about basic chemical/physical laws. Life can not form in gases. Period. End of discussion.
-
Neptune also has very nice weather and it has Triton. Triton alone is more interesting than anything Uranus and its system can offer because it has obvious active geology. IMHO the only issue is that Neptune is very far away.
-
No. Life. This has to do with physics and biochemistry, not biology. Life can not start in gases.
-
No. Life needs liquid medium to start in. There are no such things there. That's the first thing. Other than that, choice of chemical compounds is very limited. So, no.
-
I agree, an ice giant, Cassini-style orbiter is the next major similar thing we need. I'd rather visit Neptune. Uranus has rather boring satellites and is by itself a bland bluish ball. Neptune has incredible winds, prominent clouds and of course, Triton.
-
It's interplanetary space. It will jump up close to Urlum. That makes me wonder if I should wake up the crew for the aerobraking procedure or let Kerty deal with it. If the ship breaks apart, at least they will die in sleep.
-

[1.12.x] DeepFreeze (v0.31.0) 12th Sep 2021
lajoswinkler replied to JPLRepo's topic in KSP1 Mod Releases
But will it break everything if I install this into KSP 1.0.2. ? I'm using this mod as a crucial part of a mission.
