  1. You can't damage a refractor telescope by doing a Sun projection. Reflector yes (barely), but not refractors. Direct looking into the Sun using a telescope is possible, but one needs a specialized solar filter (usually Baader one) and it always goes on the objective lens. There are no alternatives. None. And if anyone has any ocular lens filters, do not use it.
  2. Very nice. So you didn't experience any overheating with DRE?
  3. As magnification is focal length divided by ocular lens diameter, and your focal length is 700 mm, your available magnifications are: a) for 20 mm ocular lens: 35x for 12.5 mm: 56x c) for 5 mm: 140x Those are perfectly enough powerful magnifications for observing Venus phases, Saturn's rings, Galilean satellites, Martian polar cap(s) if the conditions are great but barely. 60 mm objective lens is enough to collect enough light to see Uranus as a bluish dot. Ceres sometimes, not now as it's too dim. Deep space objects you can look for are Orion's nebula, Pleiades (lowest magnification), etc. You can also use it to project the Sun on a piece of paper. Never look at the Sun through the eyepiece. You're just not pointing it correctly. Always start with the lowest magnification and go up.
  4. Have you removed the objective lens cap? I bet you're just not being able to align the telescope well enough. Your lens are ocular pieces. Tell us the focal length (roughly the tube length) and the objective lens diameter so we can calculate the magnification. Always start with the largest lense because high magnifications yield low field of view, therefore slight nudge and there goes your planet. It's annoyingly difficult to point store bought telescopes to the target.
  5. Hm, what does bremsstrahlung have to do with this?
  6. You'd need a computer to simulate fields here. My brain is not powerful enough. You charge the orbiting bodies by bombarding them with x-rays. Just like Millikan did.
  7. It's not easy for me to answer because there you have a complex electrical field. It's not easy like in famous Millikan's experiment. However I'm pretty sure that if you used an atomizer with poorly volatile (or not volatile at all, like ionic liquids) liquid, you could get at least some of the droplets to orbit for some time. The key is in lots of droplets introduced into the chamber. Also, you'd need an optical device to see them, or perhaps a laser light in a form of a plate to make the droplets shining. Other than that, Coulomb's law is basically of the same construction as gravitational law. You could have, instead of a positive plate, a positive U-shaped bottle. That should give more stability the system.
  8. At least you could use it to come close to the enemy which location you know, but as soon someone comes around, they will see the glow.
  9. Can you explain what are those gray pulses the satellites sometimes emit?
  10. I remember of such game... It was on one website. I liked it very much, so I'm glad that there's one now for smartphones. I'll try it out.
  11. The only way I see it would be to pump the heat from the part of the ship facing the enemy and radiating it in opposite direction. Crazy insulators wouldn't work for long - heat creeping is unstoppable. You'd need a system which would keep your enemy-facing side at background temperature of the space.
  12. Bev7787, I'll give you rep tomorrow; it says I can't now because I've been giving it out too much recently. For any of you who are concerned about the heatshield - yes, Kron 3 does have a secondary shield. It is attached to the 3.75 m main capsule. It would be absolutely impossible to survive without it. You can't see it because it's hidden between the capsule and the decoupler.
  13. Pepe Kerman has received minimal funds to launch the first Kerbal nuclear fission reactor in orbit, as a test of possible future source of electricity for manned missions to Urlum system and beyond because RTG units have t1/2 of a little over 8 years, meaning there would have to be too much of them on a ship to guarantee fast enough power generation upon returning home. There are no signs of unrequested fission surplus, so the Ministry has approved additional funds for more research.
  14. It would be better if you said the exact speed, because "around" can be +/- 10 or 50 or 100 m/s, and therefore votes could overlap. Those of you who gave approximations are still in, but I'll use your values as exact. Reenty speed will not be the speed at the moment of impact into atmosphere, but the maximum speed achieved during reentry. I presumed you already knew this, but there's no harm in mentioning it.
  15. It would obliterate Kerbin's surface and cause disastrous tectonic disturbance at the antipode. Lots of the lithosphere would be peeled off and huge lava seas would form. All water would evaporate and form a global dense white cloud, making it look like a small Venus from orbit.
  16. That is a false colored near infrared photo. This is how Titan looks like in visible spectrum. I'd leave the Joolean system as it is, and introduce new worlds for the new gas giant. For example, Outer Planets Mod did an amazing job with it.
  17. Time to pack stuff and go home. All fuel, food, oxygen and water were transferred to the ship, and all waste products in the lander. It was strapped of instruments and RTG units and pushed away from the ship. More than 6500 m/s are now in Kron 3, but KER doesn't show it properly because the tanks are not properly fitted with fuel lines. Escaping the SOI of Eeloo. Finally, the last of the lateral tanks were jettisoned. Slate was used as a slingshot. During the coasting period, an interesting stellar event was visible - partial eclipse of Slate by Eeloo. Slingshotting was a brush with death, but Jebediah is an experienced pilot. Less than 2.5 km above Slate, Kron 3 zipped at more than 3 kilometres per second. Jeb was the last to freeze himself. Screenshot taken at the edge of Sarnus' SOI shows the planet in the distance. Ship's Kerty computer made one last final burn before going into hibernation. Reentry will occur somewhere in the northern hemisphere. Future course correction will be needed to avoid burning up. Kron 3 is now in dormant mode. Main radiators and antenna dish are closed, as well as scientific instruments. You gotta be careful about them meteoroids. 2852 m/s remain, which is not enough to slow down enough to enter circular orbit around Kerbin, but might turn useful because DRE is on hard mode. Almost 2 Earth years until a wake up call from Kerty. Mass of the ship is 42.43 t. At this point I'm opening a betting pool. Predict the reentry speed. (maximum achieved during reentry; enter exact values; closest one wins) All participants get tasty rep. The winner's prize is an opportunity to suggest name for the Kron 4 lander (future mission to Urlum, might start after KSP gets into v1.0.). Yeah, I know it's not much, but the Kerbal government doesn't have much money to spend on trivialities.
  18. This is already the case with non-GM hybrids. It's nothing new. Usually the second generation seed isn't sterile, but it gives low yield product or low quality (smaller plants, different traits) when planted, so there's no use of it. The reason is simple mendelian genetics. It's a dirty lie made by the anti-GMO nutters that buying new seeds each year is something new and tied to GM plants. It's a normal policy and that's how things work.
  19. This ship was designed so good (fuel-wise) that it might actually be capable of visiting Urlum's system, and I mean immediately and starting from Kerbin. With all that load removed, the delta-v jumps to huge numbers. The plan for Eeloo was kind of like this. Braking was a piece of cake. And so was the landing near the probe. Bob was sporting one of Kerbal new EVA suits for a while. The probe had its RTG completely depleted, but still lots of charge and xenon gas. The press loves photos like this. Contemplating about the end of a long mission. There was really nothing else to do on Eeloo's surface so it was time to go home.
  20. Glass of seawater won't kill you, either. Doesn't mean it's a good thing to drink. Sublethal doses of poisonous things also bad and you don't need to die to do some damage to yourself. Indeed, hybrids were patented long before they were transgenic.
  21. Urine is not safe to drink. It is sterile (if you're healthy), but it is not safe to drink. It contains lots of toxic stuff kidneys have been carefully removing (while spending a buttload of chemical energy) from your blood.
  22. I don't think anyone feels easy with regards to the economic issues around some instances where GMOs are used. There are examples where it gets ugly. But that's never an argument to trash the technology.
  23. This should be merged with KAS. Hopefully one day even a stock feature. Good work.
