Livestream coming soon
SpaceX's internet-satellite megaconstellation will start taking shape very soon.
The company plans to launch 60 of its "Starlink" broadband satellites this week, likely on Wednesday (May 15), SpaceX founder and CEO Elon Musk announced via Twitter over the weekend.
All 60 spacecraft are crammed into the payload fairing of a single Falcon 9 rocket, which will lift off from Florida's Cape Canaveral Air Force Station. The launch window on Wednesday runs from 10:30 p.m. EDT to midnight EDT (0230 to 0400 GMT on May 16), according to Spaceflight Now.
A minimum of six more 60-satellite launches will be required to provide "minor" Starlink coverage, while 12 more will boost the coverage to "moderate," Musk said in another tweet last weekend.
Kinda cool that they effectively look like server racks, as that's what they are.
How do they reach their proper orbits?
Do they all have rocket engines & fuel with them to reach the correct orbits?
I wondered this too. It'd be too complicated to give them all kickstages, so maybe the MVAC engine will have to re-ignite quite a few times to deploy them all properly?
They apparently have Hall-Effect thrusters for positioning.
Is it possible you could give me an explanation for what Hall-Effect thrusters are? Speak to me like I'm a 5-year-old.
Pic with banana for the size reference?
At first I thought it's an apartment block/building.
You aren't far off:
This is just the 1st stage with no fairing but apartment block is about right.
I don't really know
Ah, Ion engines are actually something I do understand. They're super efficient but I always assumed they were quite complex, so thought making 60 would be expensive. Cool.
I always tried to use them in KSP but their burn times were so long even though their ISP was good.
I believe the lighter the vessel is, it becomes easier to maneuver the vessel with this kind of engine? (explain pls)
I mean, the smaller the vessel, the higher the thrust to weight ratio.
If you have a tiny Ion engine on a gigantic vessel, it'll take hours to complete a burn.
Manoeuvrability in terms of attitude control is entirely dictated by stuff like RCS thrusters and reaction wheels though.
Press kit added, it contains more interesting details on Starlink.
Stream started, immediately scrubbed due to weather (high altitude winds, as usual). Pushed to tomorrow.
Anyone know if it is still happening today?
It was but scrubbed again
Delayed until next week due to software update for the satalites.
