The fastest and cheapest way is apparently to get a gravity assist from Venus but I'm not sure how often that window occurs.
More often than waiting for Earth and Mars to align.

Earth - Mars is every 26 months.
Earth - Venus is every 19 months.

Longer flight time though I expect.

Yeah I think I'd misinterpreted it on a first glance. Looks like the flight time's longer but the total duration of a return mission would be shorter because you can go closer to the return window. So not much point for one way cargo or test missions, unless you want to take a look at Venus, but worthwhile for a crewed mission if you don't want to spend the best part of a year on the surface of Mars.

And you get a rather pretty flyby of Venus as well for a bonus.

One of the options for Apollo was a manned flyby of Venus.

That’s the plan.
Tank farm activity/venting started a couple of minutes ago.

NASA Spaceflight stream here.

Possibility of launch within next 30-60 minutes.

Really shouldn't have missed out the "applications program" part of that Eric; via Venus is a bloody long way to get to the moon. wink

Twitter says range violation (again!!) and people back on the pad so a fairly long delay or more likely tomorrow I guess

The nearest they got to that mission was Skylab.

Dodgy valve at the tank farm was what I heard. Still on - fingers crossed.

Twitter now seems to think 10-20 mins.

I watch the labpadre and NSF stuff all day, this might be it.

I’ve actually had a bottle of champagne ready for when it lands - been stuck in the fridge since December rofl

It’s even got a Starship on it

They’ll say quarter past and then it’ll go up at 8!

What is everyone’s preferred YT channel by the way?

Live I use Nasaspaceflight (https://www.youtube.com/watch?v=XOQkk3ojNfM)

Marcus House does a good weekly round up

And, of course, Scott Manley for analysis

Last time with SN9 I asked that question and 2 mins before launch the offical SpaceX YouTube started its live stream which included onboard camera views, which I presume all the other ground based commentators miss out on.
