[@arthurbriand2175]

Considering that two years ellapsed and Bill had no idea about the sail, that means they created that solar sail in 2 years, implemented it into Sojourner that was an already completed design, did the tests... All that in secret without anybody leaking. I know their space programs are eons ahead of ours, but the logistic seems Impossible. Great scene though.

[@DavidKnowles0]

See they don't muck around with decades of testing in this universe. They think of a solar sail and they stick on a mission to mars. Solar sail is a relatively simple technology.

[@Fedaykin24]

@@SciMan314 Whilst Margo was giving information to the Soviets she wanted the United States to win the race to Mars, to that end she had given the design for the NASA Fission engine to the Soviets but with incorrect performance specifications. The information given was enough for the Soviets to safely operate Mars-94 but be at a performance disadvantage to Sojourner 1 with its perfected engine and Solar sail. The information she had given was enough to keep her lover alive so there was no need to reveal the secret Solar Sail. She was effectively playing both sides with the aim of getting her lover out of the Soviet Union some how whilst also ensuring the United States won the Mars race. It was a dangerous game that she almost got away with if not for the suspicions of her prodigy. The failure of the Mars-94 engine gave her the leverage to get her lover out but the cruel irony is she was found out just as he was got out of the Soviet Union forcing her to be smuggled out to Russia during the chaos of the bomb attack. My gut feeling is they are going to play out the collapse of the Soviet Union albeit delayed a decade or so with Margo in the strange position of being a traitor, she still has a part to play albeit I am not sure how.

It possible that Bill knew about the solar sails but they were still in early testing when he left. He did get suspicious when they started playing sailing songs.

[@Iskelderon]

An acquaintance worked on the ealy German project to send a solar sail experiment into space, so it was fascinating to see this in action. Only thing the show got wrong is how you'd unfurl the carbon masts, on the CG model the pipe just extends.

[@poabott]

Actually this is because in 1979 NASA first discovered Extendo-Carbon, a hyperdense material that could fold it on itself which would later be used by the CIA to create the ultimate Inspector (joke) (not even a funny one)

[@charles_dingus]

I'm no physicist but how would a solar sail actually help in a race to mars? They would need to be off course to start and then continually correct the course with the thrust from the sail. If they were on course from the start using a sail would change their trajectory away from mars, and seeing how the burn will always be away from the sun, wouldn't the only thing they could achieve be making the trajectory to mars longer?

[@Iskelderon]

@@charles_dingusOn such a long trip, it can add up as an added advantage, bus so far we've mostly used it for light-weight research payloads.

[@charles_dingus]

@@Iskelderon But how would it be an advantage? I'm talking about the orbital mechanics side of it. As I understand it they were already on course for mars, and any changes to that should mean they will go off course, so by opening the sail they should be thrown off course.

[@Iskelderon]

@@charles_dingus It was simplified for the sake of TV convenience, but you could use it to your advantages if the path is right, since Mars is further out in the solar system and therefore the solar wind would be "blowing" in that direction. You'd ideally pick a timing where when you leave Earth, Mars is mowing in your direction (meaning, the Earth is ahead of Mars on the rotation around the sun). Not sure if that's a year on the show where that would be going on. In this situation, you'd more fly out from the sun and let Mars come to you.

[@michaelr8189]

Some people have already called out the questionable logic in hiding such a feature, but I'm more curious about it's trade offs. If you can afford the complexities and weight to attach a giant fold out solar sail, you can also just simply add more fuel in it's place. I don't know how much propulsion a solar sail like that can actually provide over a trip to mars, obviously I'm a not a rocket scientist, but I think it's fair to guess that it couldn't actually be enough to justify the extra mass. It's a fun concept to play with in a story like this though!

[@JezOnYT88]

So here's where my inner engineer and scientist comes out. They'd need a sail multiple times larger than that to get the boost. IIRC for a small shoe box sized instrument you'd need a sail that is 10km x 10km in size to have a noticable impact on your speed. So for a shuttle we'd be talking about a massive sail.

dramatic effect

[@chemicalhap]

To get the right telemetry...and probably the optimal amount of speed to start from...so the sail accelerates them at the correct speed

[@Cyynapse]

i like how they did all this and north korea still beat all three of them

[@karantov1]

Neerva rockets. But TV is to cowardly to explore that answer.

[@planetsec9]

Phoenix should have just countered with an electric/magnetic/plasma sail deployment, they're more powerful than solar sails.

@@robertbradbury7921 Who cares? What even is 'Woke' in this context? Why be so sensitive about being more technically correct? IMO, technically correct is the best kind of correct. Unbunch your tighty whites and go touch some grass rather than trying to be some kind of arbiter of words or thought police on the internet, because down that road, lies madness.

would there be triangular sails in the future to travel from Mars back to Earth???

[@SaltyCanadian]

Solar sails are a real concept and are being demonstrated in orbit with probes right now, in 10-20 years with the right funding we could make something like this

[@hmr200subs]

No. Since the photons will always be radiating away from the Sun, it will always have an outward thrust, e.g. not towards Earth, and towards Jupiter, Saturn, etc.

I still don't get it how phoenix was first if sojouner 1 had a 384,400 km advantage because it took of from the moon... (I haven't watched the series so I don't know if they say why in there) If it was taking of from the moon, how was phoenix, which was from the earth, somehow first?

[@Jogeta5]

Pheonix was ready to launch first, but Sojourner and Mars-94 had to rush and play catch up to even launch in 1994 instead of 1996.

[@unusualusername8847]

Phoenix has better engines than Sojourner and Mars-94, the specific advantage of the methane engines were they worked better in a vacuum and were faster than Sojouner (and Mars-94) in said vacuum.

[@hmr200subs]

@@unusualusername8847 Sojourner and Mars-94 both had NTRs, so they actually work better than Methalox, since they have higher specific impulse.

[@unusualusername8847]

@@hmr200subs I just remember they said the advantage of methane was in a vacuum according to the person behind Phoneix.

[@hmr200subs]

@@unusualusername8847 Oh, idk. Maybe compared to another chemical fuel? Because, like I said, nuclear rockets have a much higher specific impulse (In layman's terms, efficiency.)
