Chapter 1; The Discovery Robert Baker was in his mid-forties with graying brown hair and a slightly lined face. He graduated from the U of Hawaii with a master's in astronomy, and got a job at a local observatory where he and his team studied pulsars, neutron stars, quasars, and black holes. His team of 27 people mainly cataloged newly discovered objects, but they sometimes looked for the objects themselves. Robert was also looked at as one of the most influential people in the state, as he and his team were some of the best in Hawaii. I'm not the only guy who helped proofread.

Atlas2342 Posted March 16, 2016 Share Posted March 16, 2016 (edited) Hey, Spaceception, the first chapter you posted here, is it the final one? If thats the case, I'll change it to what Bill Phil wrote... Edit: Oops nevermind, it was my mistake in the first place, sorry... Edit: Fixed it, sorry...

Not the final product, when I publish it to kindle )Probably) I'll likely make it 3x longer So when I do that )Probably late this year/early next year) I'll need help with that as well.

I think that would only be useful for interplanetary spacecraft using chemical fuels, not interstellar journeys using slow accelerating fusion engines, but if you have a trajectory towards Lalande 21185 for something like that where the added velocity is actually useful, you can PM me (Using a simplified description) Also, instead of building near the Sun, how about accelerating towards the Sun?

Accelerating towards the sun needs too much delta v (direct) or time (bi-elliptical transfer) And it depends on how slow you accelerate. Since your acceleration is 1 G or so, that's probably plenty to make launch near the Sun worth it. Wasn't it Wolf 359 you were working with? Either way, I can see why you chose Lalande 21185 (low chance of tidal locking, not too big, and not binary), but the high inclination of the star could really use a gravity assist to get to Unfortunately, there are no stars nearby to do a gravity assist on the way to Lalande...

Well, the colonists in question use SSTOs to get to Geostationary orbit to the Starship, so do you know how big one would have to be to get to like Mercurys orbit or something? Yeah, that's why I switched to Lalande Link to comment Share on other sites More sharing options...

Spaceception Posted March 30, 2016 Author Share Posted March 30, 2016 (edited) I think the planet could look like one of these; A planet with roughly the same land water ratio as Earth with a lot of plant life and very little desert. A planet with little water and lots of desert with little plant life. Or a planet with little water and lots of plant life. There's a very good chance I'll be able to get Space Engine in the next few weeks, so I'll come back with a much better looking example I put the first chapter onto google docs, and it's a bit over 12 pages long, in a couple months I'd like to extend it to 18 pages, but for now it'll do, anyway, when I'm finished it'll likely have 176 to 190 pages, not exactly novel type, but for my first novel I think that's pretty good Edited March 30, 2016 by Spaceception Link to comment Share on other sites More sharing options...

Use a SSTO to LEO, and a reusable Space tug to GEO. 1 hour ago, Bill Phil said: It takes more energy to build it there than to build it in LEO and launch it. Considering it takes 9.8 km/s to get to LEO, I doubt it. You would only want to build a starship in LEO if time was of the essence, and you needed to get out quickly, without time to get mining equipment to sub-mercury orbit.

Okay, but the SSTOs will also be used to get the colonists down to the surface, I can lower the height of the Starship though, that's not to hard. Well, it's going to be done over 15 years.

And it takes an extra few km/s to leave Earth SOI, and then you have to lose a lot of the kinetic and potential energy of Earth orbit. Link to comment Share on other sites More sharing options...
Spaceception Posted March 31, 2016 Author Share Posted March 31, 2016 Here's the very rough descriptions for all but one of the planets around Lalande 21185 I imagined, "Earth 2" won't be described until later in the novel, as well as more stats Lalande 21185 b Hot desert subterran, 15 day orbit. Lalande 21185 c Hot desert subterran, 33 day orbit Lalande 21185 d Warm desert terran, 46 day orbit Lalande 21185 f Cold Ice world subterran 136 day orbit Lalande 21185 g Frozen Titan subterran 2.3 year orbit Link to comment Share on other sites More sharing options...

Well, it's going to be done over 15 years. The height of the starship is not that bad... It's the fact you are using SSTOs when using TSTOs or 3STOs could offer an enormous performance advantage. I can see what you're going with this, but the problem is that a Saturn V-mass carrying SSTO to LEO is HUGE. For example, Rhombus: http://www.astronautix.com/lvs/rombus.htm had a payload of 450T to LEO. Keep in mind, this uses expendable drop tanks, so a full SSTO would be even bigger, and even more massive to do the same to GEO. I can see why you want an SSTO, but I think you may be better off building it with much smaller SSTO+ Space tug, and just make sure that it can run with very little maintenance, and basic ISRU refueling. Pretty difficult, but if you can make a interstellar drive Another option is just building that spacecraft in Lunar orbit, and carrying resources to and fro the moon for a large amount of the mass the spacecraft needs. Mainly more basic things like Shielding, and construction... It would reduce mass liftoff from Earth, but you need to create huge amounts of expendable infrastructure... Or build it in Vulcanian (sub mercury) orbit via asteroids. I have no clue where your population is on space exploration. Are there manned colonies throughout the inner solar system? Then this option may be viable. If not, probably not. Link to comment Share on other sites More sharing options...

Alright, what about a Dream chaser type craft, only 3x larger, capable of holding 20 people and 13.6 metric tonnes to LEO, 1200 km high, not as big as my original design, and can be hauled up by a Vulcan rocket. Also, I guess there could be an unmanned mining base on the Moon with Extraplanetary launchpads installed , with space tugs that can haul construction material from Lunar orbit to LEO. I haven't gone far enough yet for me to not be able to change the story. Edited March 31, 2016 by Spaceception Link to comment Share on other sites More sharing options...

I haven't gone far enough yet for me to not be able to change the story. You pretty much described a modified Space Shuttle. And you want it on a RLV, especially one able to use ISRU and need minimal maintenance due to the massive amounts of material needed, and the fact that you want to use this like Interstellar's Ranger. Depending on the profile, I would stick to a 2 or 3-stage reusable Saturn V-payload rocket for my interstellar drive, and use lunar mining and space tugs. Also, 12,000 km high is within the Van Allen Belt. Bad place to build. https://en.wikipedia.org/wiki/Van_Allen_radiation_belt I'm assuming your society has always stayed within the Earth-Moon system? Also, for the storyline, I would anticipate the black hole being obvious before it heads in the solar system. We would have plenty of time to make sense of it and take action.

Okay. 1200 not 12000 NASA has done 1 Mars semi direct mission prior, but nothing on the Moon. (And I'll be putting into the extended first chapter) I've said earlier, and it's mentioned in the first chapter, the Black Hole doesn't get detected until it pops into existence a few hours prior, and I do have a "Scientific" Spoiler Not really, it's more of a sidestep, but it'll make sense explanation of how it get there.

Probably not very good for landings, since you need a large runway. I would much rather do a vertical landing of sorts, probably with engines. 10 hours ago, Spaceception said: Okay. 1200 not 12000 NASA has done 1 Mars semi direct mission prior, but nothing on the Moon.

Then it's probably better to build it up via lunar and Earth resources, and do a long burn out, instead of going into the Sun, even though it takes more fuel- Jupiter may not exist to do a gravity assist to get down to the Sun once we get there But at least maybe do a oberth burn to LEO- though that might not matter much, TBH.
