SpaceX could write history today, if the Crew Demo-2 try #2 launch will commence
Slightly off-topic, but I guess everybody that likes computer hardware also is at least interested or fascinated by spaceflight. Something fairly unique is happening later today, SpaceX in collaboration with NASA will launch a manned crew into space with astronauts Robert Behnke and Doug Hurley.
To date, it has been nearly forty years ago that NASA started with the Space Shuttle project. Meanwhile, of course, there was China with its Shenzhou capsule and .. the very reliable Russian Soyuz which has been used for the past nine years to bring crew from and towards the Internation Space Station, that after the Space Shuttle was phased out. Today it's SpaceX's maiden voyage in terms of their first crewed flight with its Crew Dragon capsule, a commercial enterprise from founder Elon Musk (Tesla). I decided to embed the flight takeoff, hopefully, it'll go well without any issues and delays due to weather.
You can watch the Livestream below the launch (if all goes as planned) is at 3:22 p.m. EDT, or 19:22 UTC, with a backup instantaneous launch opportunity available on Sunday, May 31 at 3:00 p.m. EDT, or 19:00 UTC

I really hope everything will go perfectly, without a single glitch worth noting.
You need to enjoy the scenery when you take a long trip.

I read they won't connect with the space station until 19 hours after take-off. Anyone know why it takes so long? It's a pretty short distance.

They are going to test the spaceship - manual controls and so on. But 19 hours does sound like a long time...

Launch scrubbed due to weather. They will attempt a Saturday launch.

The most efficient way to get in orbit is not straight up but is to do a gravity turn early on from the side earth is already spinning after you reach your highest point you burn side ways to get your self in orbit and make the orbit circular, after you successfully get in orbit you have match the inclination of the target that is also in orbit and slowly speed up to gain ground then you slowly burn the opposite way to reduce your speed or often use thrusters for this job so you end up connecting gentle with body ....thats the most efficient way to do this ....burning straight up is not an option a) needs a lot more fuel ....if you do not add kinetic movement side ways to get in orbit ....what goes up then goes back down :p
B) the more fuel you add the less efficient the of fuel is ....since to use the fuel you have to carry it so extra weight from the fuel and the storage pieces for it... If you add more engines cause the weight is to big then you add even more weight and higher consumption etc etc ....anyway 19 hours is not really that much it is rather interesting but no human trip to space where ever straight we calculate things down to the gram using even the earth the moons gravity etc to give us extra push and conserve fuel so all you have to do is burn on the most efficient point till you reach escape velocity and another burn to get caught but some others body gravity ; venus moon etc where again you burn to get in orbit etc etc
