SpaceX to Launch 60 Starlink Satellites at Once, and More

SpaceX CEO Elon Musk reveals radical Starlink redesign for 60-satellite launch

SpaceX CEO Elon Musk has published the first official photo of the company's near-final Starlink design and confirmed that Falcon 9 will launch a staggering 60 satellites on May 15th.

Known internally as Starlink v0.9, this mission will not be the first launch of operational satellites, but it will be the first internal SpaceX mission with a dedicated Falcon 9 launch. Additionally, the payload will be the heaviest yet launched by SpaceX, signifying an extraordinarily ambitious first step towards realizing the company's ~12,000-satellite Starlink megaconstellation.

Put simply, SpaceX's Starlink v0.9 launch is extremely unique for several reasons. Aside from the unprecedented step of launching 60 spacecraft weighing ~13,000 kg (~30,000 lb) on a developmental mission, both the form factor of each satellite and the style of dispenser/payload adapter has never been seen before. SpaceX appears to have settled on a square dispenser with four separate quadrants for satellites. The satellites themselves look truly bizarre – it's actually difficult to discern where one spacecraft stops and the next begins. Nevertheless, it appears that each Starlink satellite is a relatively thin rectangle, possibly with a squared top and bottom. It's also possible that they are all around rectangular and that the dispenser instead has two main sections.

Elon Musk & Jeff Bezos Can Save American Households $30+ Billion with LEO Satellites

Low Earth Orbit (LEO) satellites are still in their nascency, but analysis of BroadbandNow US market pricing data suggests that the technology could save American households more than $30 billion per year by intensifying broadband competition.

LEO satellites, such as the constellations planned by Elon Musk's SpaceX Starlink project and Jeff Bezos' Project Kuiper, promise to bring low-latency broadband internet to millions of Americans. LEO satellite orbit extremely close to earth, between 99 to 1200 miles versus 22,000 miles of traditional GEO satellites, which means less time to transfer information (lower latency) and a quality of service comparable to wired broadband cable and fiber providers. The arrays will be precisely mapped into massive constellations to maximize coverage.

SpaceX stacks orbital Starship sections as Elon Musk teases June 20th event

SpaceX CEO Elon Musk says he will provide a public update on the development status of Starship and Super Heavy in an official presentation later this summer, possibly as soon as June 20th.

Meanwhile, SpaceX's South Texas team have been busy at work on both Starhopper and a newer Starship, said by Musk to be the first orbit-capable prototype. In the last week, technicians have begun stacking several sections of the vehicle's stainless steel hull, all fabricated and welded together side-by-side. On Thursday, May 9th, this progressed to the installation of the Starship's first gently tapered nose section atop its cylindrical tank section. Likely the second- or third-to-last major stack before its aeroshell is assembled into one piece, the orbital prototype is starting to truly resemble a real Starship.

New satellites could save Americans $30B on monthly Internet bills, report says

Low Earth Orbit (LEO) satellites from Elon Musk's SpaceX Starlink project and Jeff Bezos' Project Kuiper could save American households more than $30 billion per year by introducing more broadband competition, according to a report from BroadbandNow.

"The arrival of this emergent technology is likely to drive down monthly internet prices for hundreds of millions of Americans," the report said. In short, the more broadband Internet services available in an area, the lower the price consumers will pay on average.

Elon Musk shows sneak peak of SpaceX's internet satellites

SpaceX satellites designed to beam internet coverage from space to under-served areas of the world have been revealed by Elon Musk ahead of their anticipated launch later this week.

The entrepreneur showed off 60 "flat-packed" satellites loaded on a Falcon 9 rocket, which could be sent into low orbit on Wednesday – but warned that its latest attempt could easily fail.

"Much will likely go wrong on first mission," Mr Musk wrote on Twitter, adding that it would take six more similar launches to reach "minor" broadband coverage and 12 for "moderate" service.

    What is the latency of these things? Some very quick math confirms this orbit is farther than the local CO is to my house, but closer than Amazon's data center. What would standard "ping times" be for folks?

    I suppose when we put server farms in space to help with cooling and we can run stuff at temps near absolute zero, that's when the server farms will be closer to my house than Amazon's data center.

    Did you include the velocity factor of coax/fiber? EM waves travel at approximately 0.66-0.8c in those media [wikipedia.org].

    One press release said that the new lower orbit that was recently approved would allow for pings as low as 15ms. A quick calculation of perfect speed of light with the distance, would get the signal to the satellite one way at about 1.5ms, so 3ms to get to the end point and another 3 back, would be about 6ms ping, if everything was perfect. So, add in a bit of latency due to atmosphere, and real world performance. 15ms sounds theoretically possible and 30 - 50ms real world performance seems reasonable. At those ping rates, you can do pretty much anything. Assuming, the connection is stable and the data cap isn't low.
