    Uptherams reacted to Carl Sagan in Starship and a Human city on Mars   
    I love that there seem plenty of space geeks on here. Something that's going to come increasingly into the public consciousness over the next few years will be the work from Elon Musk's SpaceX to transport many tens of thousands of Humans to Mars to build the first sustainable settlement on another world. It sounds like fantasy, but the amazing thing is they're doing this in public view in Boca Chica, on the coast of Texas, and we can all watch. There are lots of livestreams and over the last couple of years a barren field has started to be transformed into a shipyard. But not for ordinary ships, for spaceships. The goal is ultimately to have completed ones roll off the production line once a week. And each will be able to take a hundred people at a time.
    The optimal time for going to Mars in terms of minimizing fuel (the launch window) comes round every 26 months and the plan is to have a fleet of Starships gather in Earth orbit that will then travel to Mars together, before returning to bring more settlers for the next launch window. Tickets will cost you about $250k but there'll be high baggage charges on top I should think. The secret to the low price comes from reusability and scale. SpaceX has pioneered rocket reusability and landed 65 or so "first stages" (the main rocket booster) after orbital insertion. No other company has done any - they're at least a decade ahead of the competition, but the competition should worry because their pace of innovation is extraordinary.
    The new rocket being built in Texas will be the first fully resusable craft where all of it flies again and again with minimal refurbishment, just the same as an airplane. The top section where the passengers and cargo will go is called Starship and the lower section to help boost it into orbit is called Super Heavy. In a dramatic innovation, instead of being built from an advanced carbon fiber skin these are both made from stainless steel. Making them a fraction of the normal rocket price. The Super Heavy booster is needed to escape Earth's gravity well. Once there it will return to Earth and launch half a dozen tankers to refuel Starship in orbit so it can fly much more quickly than normal to Mars (normally a spaceprobe just has enough fuel to reach escape velocity and then coasts all the way to Mars). Refuelling in orbit hasn't been attempted in the past, but is a technology we need to master to become a spacefaring species.
    Because Mars is smaller, with lower gravity (one-third of ours) the Starships can be what we call "single stage to orbit" when they take off from the red planet for the return journey. We'll build factories on Mars to manufacture fuel through a process called in situ resource utilization (ISRU), which is another technology we need to master to become spacefaring. And because they can carry so many passengers at a time, the price of the trip becomes a lot cheaper as it's divided between many more people.
    The Super Heavy booster will be quite similar to the SpaceX Falcon 9 rocket, just a lot bigger. So in principle SpaceX already knows how to design, build, fly and land that. They have started on the harder problem first, by developing Starship, the first ever fully resuable second stage. This week there's been a lot of work on the eighth prototype (called SN8 standing for serial number 8 ) which will probably be the first to attempt a high-altitude (15km up) test flight as the key trial of the novel landing system (the "belly flop"). Before now three different partial Starships have flown 150m on one engine only. It's been amazing to watch. Here's the Starship SN5 "hop test":
    While SN8 is the focus at the moment, also partly built are SN9 through to SN14, each better than the last, and also the very first Super Heavy booster (SH1) is being constructed. There's a good chance that the first Starships (without people) will go into orbit and return next year. There'll be hundreds of test flights before they start taking crew, but I'd expect the first uncrewed Starships to leave for Mars carrying cargo and experiments either late 2022 or early 2025.
    The reason SpaceX was founded was to safeguard Humanity's future by building a self-sustaining community on Mars, the aim to reach a population of a million by the end of this century. This is why the company is privately held and you can't buy shares, because shareholders might look at the amazing technology and say Mars colonization is a waste of money when we can do a lot of profitable stuff closer to home. However, NASA wants to return to the Moon by late 2024 (though after the US election this date will slip) and are contributing funds to create an adapted Starship to land on the Moon (the normal engines are too powerful for this because the rocket is so big, so SpaceX are going to add smaller thrusters higher up to do the job). However, Elon Musk has said it's easier to just go and land on the Moon than jump through all NASA's certification to say they'll allow someone to launch astronauts safely to the Moon.
    I hope we'll be able to keep this thread going over the next decade while we watch developments until the first Humans get to land on Mars, and it can be a wonderful record of the progress that took us to that point.

    Always has been. Even with us. Sacrifices personal prowess for helping the team. A shame really, kind of player you should allow a free role, especially because he'd still help the team out, versus some flair player's who couldn't care less.

    Both simply don't get to be the flair player's they are due to the teams they play for. If either played for a team in the top 6, they'd fulfill their potential. But both have shown they are more than good enough at that level. 
    I'd have both back. Especially Jeff right now. Maybe we'll have a cheeky punt. Offer an inticing promotion clause ??

    I have a lot of respect for Keogh as a player and as a player and feel sorry for what has happened to him. He served us well and I wish him all the best for the future in what ever role or employment he gets. For me he will always be a Ram

    That's fair enough. But he's been here almost a decade. Played hundreds of matches. Missed barley a minute. While he has been at the club how many players have simply collected their wages or were barely even trying to do their job. How many have missed large periods due to their own mistakes, purposely or accidentally. 
    This whole situation couldn't have been handled any worse. 
    My own personal opinion is that Keogh still wants to play for us. To see us make the Premier League. Before this whole fiasco, he looked like he could play at this level for another 5 years. I'm not writing him off. Davies has come back and looks better and fitter than he was before he first got injured. Should he take a pay-cut, I believe so. But the clubs approach has got to be more nuanced than this.

    Sad state of affairs when that might end up being the case for a player that was easily on track to be in our clubs top 10 most capped players.

    You don't know what the 'deal' was. This also won't stick in court. They can't offer him a new contract and then sack him for gross misconduct when he rejects it.

    So the 2 main culprits have been given a fine and are already back in the team and playing like nothing happened, but the passenger who's already suffered the most is now being threatened with being sacked? Sure he's the captain and should know better, but if you're exploring the possibility of sacking him then you should have probably done that with the other 2 as well.

    On the blue light point. Anyone can download a piece of software called f.lux for free.  It mirrors daylight and after two days or so of using it you are completely unaware that you are using it. Blue Light is a huge problem, even for people who don't think it is for them. I recommend everyone uses f.lux immediately.
