@fcain @varunversion1 @Erdayastronaut @SpaceX Would love to do exactly that

@Cosmic_Penguin 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.

@fcain @varunversion1 @Erdayastronaut @SpaceX 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.

@John_Gardi @13ericralph31 @varunversion1 @Erdayastronaut @SpaceX Rotate on one axis. Magnetic torque rods for desaturation of momentum wheels.

@GoForStaging @13ericralph31 @varunversion1 @Erdayastronaut @SpaceX Yes, already planned. We avoid use of certain lower Ku frequencies specifically for radio astronomy.

@1DarknessSoul5 @SpaceX 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

@13ericralph31 @varunversion1 @Erdayastronaut @SpaceX 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. https://t.co/83MwIZAEP6 https://t.co/NllMXregRg

@varunversion1 @Erdayastronaut @SpaceX 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. https://t.co/OuWYfNmw0D

@Erdayastronaut @SpaceX No, Raptor uses a large number of coaxial swirl injectors, which (we believe) achieves highest theoretical mixing/combustion efficiency.
