Let's face it, gamers are the reason why graphics cards are so advanced now😁

@elonmusk · 28 мая 2019 г.
True. I’m a gamer & my boys are too. Starlink is designed to be great even for competitive twitch reflex games.

But if you can throw up a few Starlink-chassis space telescopes, I'm sure that'll smooth things over with the astro community. Especially since they'd be able to return the data quickly via... Starlink.

@elonmusk Please see if there are ways to reduce reflected light downwards from the later batches of Starlink satellites, as they seems to be "more shiny/higher albedo" than others. Maybe some coatings/extra mirrors would help. Thanks!
Elon Musk
@elonmusk · 27 мая 2019 г.
Agreed, sent a note to Starlink team last week specifically regarding albedo reduction. We’ll get a better sense of value of this when satellites have raised orbits & arrays are tracking to sun.

If they help billions of people in remote locations inexpensively access the internet, it's a price I'd be willing to pay.
Elon Musk
@elonmusk · 27 мая 2019 г.
Exactly, potentially helping billions of economically disadvantaged people is the greater good. That said, we’ll make sure Starlink has no material effect on discoveries in astronomy. We care a great deal about science.

Do the #Starlink solar panels rotate or are they fixed?
Are these moment control gyros and, if so, how do you desaturate them?
(Related questions 😉)
Elon Musk
@elonmusk · 27 мая 2019 г.
Rotate on one axis. Magnetic torque rods for desaturation of momentum wheels.

Yes, already planned. We avoid use of certain lower Ku frequencies specifically for radio astronomy.

Aiming for sub 20ms latency initially, sub 10ms over time, with much greater consistency than terrestrial links, as only ever a few hops to major data centers

I am all for Starlink for the many potential benefits it may bring, but I think you may be downplaying the potential for disruption. Of those ~5000 satellites in orbit, maybe 800-1000 are in LEO. Way too early to jump to conclusions but you may want to dive a bit deeper.
Elon Musk
@elonmusk · 27 мая 2019 г.
If we need to tweak sat orientation to minimize solar reflection during critical astronomical experiments, that’s easily done. Most orbital objects are close to Earth btw, as shown by this NASA density map.

Any thoughts on starlink satellites causing space debris and lighting polluting the sky according to what some people are saying?
Elon Musk
@elonmusk · 27 мая 2019 г.
There are already 4900 satellites in orbit, which people notice ~0% of the time. Starlink won’t be seen by anyone unless looking very carefully & will have ~0% impact on advancements in astronomy. We need to move telelscopes to orbit anyway. Atmospheric attenuation is terrible.

Does the Raptor engine still use pintle injectors like the Merlin? Seems like it’s good for quick restarts and deep throttling @elonmusk @SpaceX
Elon Musk
@elonmusk · 27 мая 2019 г.
No, Raptor uses a large number of coaxial swirl injectors, which (we believe) achieves highest theoretical mixing/combustion efficiency.

Want to know how @SpaceX's Raptor engine works? Confused about what the full flow staged combustion cycle is? Why are they using methane? How's the Raptor compare to other rocket engines? My deep rundown on the Raptor is finally up! Great engine @elonmusk youtu.be/LbH1ZDImaI8
Elon Musk
@elonmusk · 25 мая 2019 г.
Super proud of SpaceX propulsion/test/materials team! One of hardest technology problems. New high temp superalloy & internal foundry needed to make it work. Foundry iteration interval is ~3 weeks from design to flight part vs ~36 weeks typical for aerospace.

Are the panels used as sails? Radiation pressure will affect the attitude at the very least so
Elon Musk
@elonmusk · 25 мая 2019 г.
Only a tiny amount. There is enough air to affect the satellites & allow some amount of yaw steering.

What does the improvement path of raptor look like? Mainly propellant changes or improvements to turbopumps/injectors?
Elon Musk
@elonmusk · 25 мая 2019 г.
Propellant stays same, but almost everything else improves. Fundamental goal is minimize cost per ton to surface of Mars.

Great video. Couple notes: Raptor designed for subcooled CH4/O2, so propellant density & thrust increase up to ~8%, as needed for mission. 380 Isp & up to 50% thrust/weight improvement over time. Merlin thrust/weight doubled from V1, but Raptor is closer to optimum.

If you're wondering how #Starlink sats will spread themselves out into their plane, Elon gave us the answer & the video above confirms it.
x.com/elonmusk/statu…
The 10 or so Starlinks spaced further out at the end are the ones raising their orbits.
Higher orbit = slower speed.
