  1. Suggestion: Add an option for dynamic planetary brightness. The option causes planets to become dimmer or brighter with distance. For example:
  2. This is an artifact that i've encountered in SVE. It only appears after the camera is above 100km. Is this a bug with scatterer mentioned under "known issues"?
  3. So there's this phenomenon called "Time Dilation", where i roughly recall, means that you will observe time to speed up for others when gravity increases. This means that when you fall into a large gravitational well, you will observe the rest of the universe to move more quickly. Using this concept, that means that when you fall into the event horizon of a black hole, you will observe the rest of the universe to speed up, right? I have a thought: When you enter a black hole, you will observe the universe to speed up. If the gravitational well is deep enough, you can see the movement of stars sped up by millions of times, you will see civilizations rise and fall, stars explode and stellar systems form, galaxies collide. The very last moment before you enter the singularity, all of time would have passed (since g approaches infinite). To keep the story going, lets just assume that you're wearing a suit that's resistant to heat, fire, and any other elements that would destroy it (spaghettification included). Black holes are known to dissipate by hawking radiation, but they take a very, very long time. However, since "all of time" would have passed once you reach the centre of the black hole, would enough time have passed such that before you reach the centre, the black hole would have dissipated away (And you emerge from the other side a googol years later) ?
  4. Update: Anomaly was not caused by the rocket itself. Either payload/ground support issues.
  5. Yup it was... Edit: My apologies, it was LC-40. I can't remember things. Another great source is https://www.reddit.com/live/xix3m9uqd06g
  6. It's rather crucial to know if the rocket did actually explode, or was it just ground support equipment. This way, we can know who to assign blame on we can know if the rocket has any flaws, or not.
  7. Would the strongback be able to withstand a strong explosion from the rocket itself?
  8. I know it's a bit late to ask this, but how fast was the stage flipped right after MECO? The boostback burn started pretty quickly.
  9. Are we forgetting about Ted as well?
  10. Making a falcon 9 rocket that is partially reusable and successfully landing it on a barge on an ocean.
  11. I've edited point 2 to include LOX. I guess its a necessity.
  12. So i have this ambition that we can send homemade rockets to orbit. I've seen some pretty cool videos on homemade rockets reaching the Karman line. What do we need to make a rocket that's orbit-capable? By that i mean it has enough delta-V to reach an altitude of above 100km and orbit the earth once. These are some of the considerations i would think separates "homemade" from "professional". I'm researching if a homemade rocket is truly possible, or not. 1. The rocket should not use any highly-pressurized fuel, or hard-to-attain fuels such as liquid hydrogen. Kerosene and LOX should be easy to get, so is solid fuel. 2. Fuel should be storable between temperatures of 10C and 70C, and in a pressure not exceeding 100 bar. This excludes oxidizer/LOX. 3. The rocket should not contain any expensive, rare metals(such as niobium). 4. Rocket core should be not bigger than 10m in height, or 1.5m in diameter. Rocket can have multiple strap-on cores, asparagus is fine. Also, the rocket built should be made with materials accessible to the common man. Milled machine parts and metal are fine, just not space-grade. Simplicity is also another factor, the rocket should have as little parts/moving parts as possible. My initial idea of a homemade rocket that can reach orbit is one that burns kerosene and LOX, with 4 small engines. It is about 8 metres high, and 1 meter in diameter. During initial ascent, an elastic rope will grab on one side of the rocket, tilting it slightly. It will snap after about 2~3m of extension. 4 fixed fins at the bottom of the rocket will put it in spin stabalization. The stage will burn for about 57 seconds, after which it will separate, revealing a second stage about 1m in length, and 80cm in diameter. The second stage will use monopropellant and an extended rocket nozzle to "reach" orbit. Crunching the numbers, however, it was terribly inefficient and could barely reach a decent suborbital trajectory. With no payload in mind, how would you design yours?
  13. Perhaps a simple way is to "stretch" the particles in the prograde direction so it looks sort of connected, without making new particles.
