breaking news hello everyone. thanks for joining me on. alison chemla, radha, and for fredricka whitfield, we have an exciting program for you today because within the next half an hour, we expect to witness the first ever boeing starliner spacecraft launched from cape canaveral, florida to the international space station. this is not a practice run this its launch has to american astronauts on board but officials and spectators are holding their breath a bit because this mission was already postponed a few times, veteran nasa astronauts, butch wilmore and suni williams are on board. and boeing is trying with this to compete with its rivals space x as nasa tries to

at this historic rocket launch of nasa is partnership with boeing. we are now just minutes away. so let s listen in live as nasa prepares ignition, sma switch to disabled position and somebody ignition disabled okay consoles of step 60 report launch vehicle status adversely alice take pressures and helium bottles stable. i was propulsion system stable. roger dent or lead gentoo think pressures helium bottle stable. since our potion system stable as gasp readings, nominal. roger, vehicle electrical the channel one avionic system
perfectly accurate, but it ll give you an idea of what we re talking about. so this is the bow, the boeing starliner capsule and spacecraft on top. this is where the two nasa astronauts are. what s below it is the atlas rocket. and this is what s going to propel the starliner spacecraft into orbit. this right here is called the rocket s upper stage. it s the center and there was an issue here during that first scrub back on may six. now, an issue again, but different. it s an issue with a sensor for a topping valve, essentially a valve that tops up the fuel inside this upper stage of the rocket they went about through about an hour of checks trying to figure it out. they ended up switching to a backup system. they think they ve got it fixed. so we are now go for launch and i should just point out, allison, the capsule is made by boeing. this whole rocket is made by the united launch alliance. so different company that s what the issue was with, as i
said, there has been a hold that s been put on the clock at three minutes and 50 seconds but in that is problematic because this is an instantaneous launch window, meaning they have to launch at precisely the right minute and second in order to perfectly rendezvous with the international space station. so i guess it s potentially likely than we could still see a launch today, but this is looking increasingly not likely that this launch is going to happen because i just don t see how how they can make that instantaneous launch window with a hole that is now this long. but again, no word on what that issue is. just just yet. no word on what it could be really. i mean, usually nasa is pretty good about updating us with this sort of stuff. but the previous issue was with something right here in the atlas five rocket. this is the center portion of the atlas
