Starship Definition and 31 Threads

In the "Andromeda Nebula" novel the author (Yefremov, 1957) describes dramatic story of a starship being inadvertently directed into the neighborhood of the "Infrared (Iron) Star" - so it was not discovered by navigators until too late. The ship is on the return route and doesn't have enough...

https://interestingengineering.com/innovation/spacex-raptor-engine-test-explosion In a tweet accompanying a clip from the footage, NASASpaceflight wrote, “The raptor testing stand at McGregor experienced an anomaly a few moments ago. The vapors from the anomaly caused a secondary explosion on...

Hi all ... its a looooong way to Proxima b so im here to brush up my cosmic wisdom chops! Will also be able to answer questions related to real steel starships, droids and hard science future tech

Can an electromagnet push the ship forward by absorbing the momentum of a nuclear explosion via a magnetic field? Im thinking this will solve the problem of constantly having to repair the eroding plate if its replaced by a magnetic field sustained by a fission reactor generating power...

Watch the progress live This is a fully stacked Starship (top) and Super Heavy (bottom). A couple of too-small-to-see cars near the bottom for scale, I also added a Saturn V and the Statue of Liberty for comparison. 120 meters tall, about 5000 tonnes when fully fueled. Twice the mass and over...

I have my own intuition on things, which I hope to correct if I’m wrong. For example, the most obvious thing is that stars won’t fly in a straight line from the front of the craft to the back if you look out the side window because the craft would be rotating to simulate Earth’s gravity. So...

SpaceX doesn't have a public test plan, but they need to close a public road to fire the engines, and road closures need to be announced in advance - including their reason. In the next days SpaceX plans a static fire (engine fires but the spacecraft is fixed to the ground), and Monday next...

SpaceX loves confusing numbering schemes, but so far we have seen five relevant test articles: Starhopper ("water tank") made a 150 m flight, Mk1 was the first full-scale prototype but got destroyed in a pressure test, Mk3=SN1 got destroyed in a pressure test, SN2 was a tank test only...

FTL and warp are energy intensive in fiction, and even real scientists calculated at first that warping space would take a planet Jupiter mass converted into energy amount. Later it was revised to only about 800 kilograms, about the weight the voyager 1 probe. Even so, that is still a massive...

Using real science we can extrapolate what hull shapes could be used, assuming we actually did have high thrust constant acceleration drives (we don't because it requires energy/mass ratios that tend to cancel each other out). So what shapes? Pill capsules are ideal for crewed vessels. Even...

In scifi, the crew jobs depend on the kind of vessel flying. For the purposes of discussion, a starship is any spaceship capable of interstellar flight within about the time it takes to travel by car to a another state or country hours or days away. The issue is that the typical starship in...

I’m trying to find something that can replace Ion engines in my Star Wars story. Ablative laser propulsion seems like a good bet because it works in both atmosphere and a vacuum and just seems better than Ion engines.

The SpaceX Starship Mk1 prototype has been damaged beyond repair 20 November 2019 during a cryogenic pressure test. Entire top been torn off. https://www.space.com/spacex-starship-prototype-anomaly-pressure-test.html

I have been researching the rocket pendulum fallacy and have gotten into some spirited debate on the subject. If I understand correctly... 1. if the thrust is perfectly in line with the centerline (and no outside forces act on the craft other than gravity) it does not matter where the source...

Previously discussed in the "Space Stuff" thread but this is a long-term project. What is Starship? SpaceX is working on a fully reusable two-stage rocket to replace the partially reusable Falcon 9/Falcon Heavy. It is the largest rocket that made it beyond the concept phase so far; the payload...

While the main problems of a functioning starship are commonly known such as energy requirements and radiation I have realized another problem when near the speed of light. The dynamic Casimir effect occurs when a reflecting object reaches relativistic velocities. Therefore a starship with a...

Upon discovering the Starship Titanic while doing some research about time travel, I was wondering what joules would be necessary to accelerate even faster to attempt a more severe time dilation: Namely, a 50,000kg ship to 99.999999999%C. Am I correct in my calculations that this requires app...

I'm not sure if this has been addressed previously, but there is an engineer who goes by the name of Dan who claims he can build a real starship Enterprise within the next 20 years. All he requires is the necessary funding, which is about $50 billion for each year, which I think is insane...

Homework Statement A starship is moving toward a space station at half the speed of light. When it is 7.00 seconds away from reaching a space station (as measured on the ship's clocks) the starship fires a projectile toward the space station at 0.600 c (as measured by the ship's crew). When...

If human can build the starship but how there having a drive engine system that have a more reliable and infinite source of fuel?

I'm trying to figure how fast this ship can reach various destinations in a story I'm working on and I have no background in advance math of any kind (If teachers had offered more interesting scenario questions like this one I might have paid more attention in class, instead they gave me those...

Starship + 2 different planets? Homework Statement The problem from my textbook is: Inside a starship at rest on earth, a ball rolls off the top of a horizontal table and lands a distance D from the foot of the table. This starship now lands on the unexplored Planet X. The commander, Captain...

Homework Statement On a Starship, which travels at 0.93c, dinner is served between 8:15pm and 8:45pm, according to the clock on the ship. How long is dinner served according to stationary observes on Earth watching the ship on a video monitor? Homework Equations I believe the...

Hi I'm having trouble with this question and would like some kind of hint on how to proceed. A photon starship starts from rest and propels itself by emitting photons in the direction opposite to its motion until it reaches a speed v. Use energy momentum conservation law to show that the...

In http://arxiv.org/abs/0908.1803v1" , 2003, Robert Frisbee offers some ideas on the design of an antimatter rocket. Crane and Westmoreland concentrate more on the possibility of a black hole starship, rather than the size or shape of the craft. I'm wondering, how many of the constraints that...

A warning is often given that if one wants to have a spaceship traveling at relativistic speeds (usually to get to another star), the ship's mass increases, making acceleration more difficult. But if it where an antimatter propelled ship, with mass being turned into energy, then wouldn't the...

the starship enterprise is cruising along at constant speed v when it encounters a mysterious space station. (enterprise = x, space station = S) http://x402.putfile.com/4/11618084116.jpg the enterprise is headed such that it will pass the space station at a distance d, as shown above. the...

If you could build a starship here and now what would it look like, what would drive it, and would it have gravity yes/no?

This gigantic thing here called the Centauri Princess, can it be built in the next few hundred years? http://www.astroscience.org/abdul-ahad/firstarktoalphacentauri.htm That would be the greatest engineering achievement in all human history...

Okay what am I doing wrong? This is the way I've been doing math for the last two years. This is annoying me. Unless I've been doing everything wrong the last two years, I feel this is correct. I realize it's most likely wrong. Someone please explain to me what I am doing wrong and more...

The Starship Enterprise initially moving with speed vo hits an intergalctic metero shower and expreiences a deceleration force given by: F = -b*e^([alpha]*v) where b and [alpha] are constants. The star ships mass is m. a) Determine v(t). b) Determine the time required for the Enterprise...
