Can non-intelligent life naturally evolve the ability to space travel ...
Over time some could randomly have the ability to survive in space by essentially being dormant while they travel. Say they land on an asteroid or another moon that has the simple resources they need to survive...a particular mineral maybe and viola, you have your space faring critters.
Interplanetary vs Interstellar travel - Worldbuilding Stack Exchange
2016年2月4日 · So if your space ships accelerate to a speed, coast at that speed, and then decelerate at the destination, a journey to even the nearest star will take tens of thousands of times as long. Thus for every minute an interplanetary trip takes, a trip to even the nearest star is likely to take several times 6.944 days.
Is this a viable theoretical method of fast interplanetary space …
2023年3月6日 · Another rationale for your design could be that if this buoy with sails is massive enough to grab whole ships and not care much, it could be more protected from the space radiation etc. Effectively a sailing hotel between planets, park your thin-foil ship nearby and come inside for safe travel (even if hibernation).
space travel - Would a manned Mars landing be possible with …
2024年8月11日 · If we continued Space Race levels of funding in our pursuit of Mars, and look at the mid-70s as when we could first prove the viability of a long term space capsule (space station), we could have maybe done a manned Mars orbital mission that could drop remote controlled probes by the late 70s or early 80s, but the risk of trying to put boots on ...
science based - Where to have a colony after Pluto?
I have a world where humans have developed interplanetary space travel that allow them to travel to other planets. There is an issue though- the speed is slow, sublight; as an example it will take at least a week to travel to Pluto, at which point your ship’s fuel tanks have run dry.
Base on the Moon for interplanetary travel
2020年1月22日 · What you really need is a pair of Lunar Space Elevators. This shows a nearside space elevator terminating at the Earth-Moon L1 Lagrangian point, which you'd use for travel between the Moon and Earth. The farside elevator would look pretty similar, but would be used for travel out of the Earth-Moon system to elsewhere in the Solar System.
How fast could inter-planetary space travel be developed?
2016年8月25日 · Interplanetary spaceflight of the kind you are talking about is more or less possible with today's technologies. Lets put the Apollo space program in perspective. As of 1942 no craft (as opposed to projectile) on earth had broken the sound barrier. That is the year the V-2 rocket did. A human manned craft broke the sound barrier in 1948.
travel - In space, do "shipping lanes" make sense? - Worldbuilding ...
The difference, in space travel, is that A and B are rarely situated in the same points in space at any two points in time. For interplanetary transit, the most efficient yet direct path is a "Hohman Transfer Orbit", basically transitioning from planetary to solar orbit along a path and at a velocity that will cause you to move between ...
space travel - A better way to do a planetary invasion?
2022年4月17日 · It's easy to miss this, because there isn't much frame of reference up in space, but reentry vehicles travel insanely fast. Apollo 11 hit the reentry interface traveling about 11 km/s, or above Mach 30. A Soyuz from the ISS, which is "only" entering from orbital velocity, hits atmospheric entry at a comparatively low 7.6 km/s, or Mach 22-ish ...
science fiction - Zero propellant interplanetary travel
2022年2月22日 · I am creating a world where there is an interplanetary network that allows planetary commuting to and from all planets and major moons in the solar system with 0 propulsion being supplied by the craft itself .
