Missed it. Any links for the next few days? 8 year old scoffed at me when the launch was aborted earlier, I was reliving the 80s in my own head.
Spent an age until 11 outside gardening, never thought to look up after the Spacex.

What's the purpose of this mission? How long will they stay up there? Silly question but will what flight path do they actually take, assuming they can't just go vertically?

Not sure if this is accurate!? Would be low on the horizon anyway on Saturday regardless of sun being in the sky.

It's a demonstration mission to gain certification to ferry humans to the ISS for NASA. The haven't said how long the mission is. Couple of days maybe this time. They will do a few orbits of earth raising altitude until the catch up with the orbiting space station

On a flat earth perhaps!

They said last night it must stay a minimum of one month docked at the space station.

Really. Missed that. It makes it a bit more than a demo mission in reality so.

So this is the first launch of a new American spacecraft since the shuttle with the first one being Alan Shepard in mercury, then Gemini, then Apollo, then the shuttle, and now spaceX.

I've seen people say that Skylab should be included and while yes Skylab was a separate vehicle it used a Saturn V second stage and was accessed using a Apollo CSM so it wasn't a new vehicle imo

And in the next couple of years we should have the Boeing Starliner (first crewed mission scheduled for 2021) and NASA Orion on Artemis 2 mission in 2023. Exciting times ahead.

SpaceX get paid to test human flight something they'll need if they want to send humans to Mars.

The US won't have to paying the Russian's over the odds for trips to space. So congress and voters like that.

There's less pressure on Boeing and Blue Origin so they can still keep their snouts in the trough while doing the bare minimum.

And Airbus are building the service module for the Orion crew capsule. It's based on the ATV that used to deliver cargo to the ISS.

Presuming Boeing can get its act together.

Their unmanned test in December last was a bit of a disaster. They'll try another towards the end of this year. If that doesn't go well hard to see them staying in the reckoning.

Doesn't look too promising for a launch this weekend.

If the weather doesn't cooperate this weekend, SpaceX could push the launch to June 1, but additional backup launch windows have not yet been announced.

June 1. Or as we call it Monday. With enough windows the odds get better.

what date would be the best for viewing in Ireland?

27th may, all other launches are too early in the day to see it as it will be bright out. There's a window on the 30th for 22:14 would be the best chance to see it but only briefly if even, as it would be very low on the horizon.

What are the estimated chances of a launch tomorrow?

60% chance of a weather violation. There's chatter going on that they might skip tomorrow's window altogether due to bad weather and aim for Sunday which looks better.

I think the ISS will disappear in a week or so until mid July. The ISS would have to be in the sky for us to see Dragons. There's always LSD though ;D

Here's an interesting video on abort options for the capsule.

https://www.youtube.com/watch?v=X2d-yWdcw44

If there is an issue with the second stage after roughly 8 and a half minutes of flight, the capsule would splashdown near Ireland, and Shannon would be used as the recovery base.

It's the same idea as was used on the Shuttles, where they would land in Spain if they had issues during a particular time of the flight. Shannon was also an option for the shuttle, but NASA preferred military bases.

If there is an abort in the very last few seconds of flight, it will be able to make it to orbit, but not necessarily the intended orbit.

Zaragoza in Spain if I remember correctly because it was said during every shuttle launch I watched live and those that I've watched back since.

Weather conditions at the Cape permitting the launch will be shown live but forget about seeing anything in the skies over Ireland.

Completely unrelated. That's a test article for Starliner. Nothing to do with Falcon 9 or Dragon.

Jesus rte just now on TV when reporting that the second attempt at the launch today dropped the explosion into the report. Why ? It's not connected at all FFS.
