1. The next space race: SpaceX internet satellites go this week
SpaceX is set to launch its Falcon 9 on Wednesday, May 15th, from Cape Canaveral in Florida. But this one isn’t for a customer like NASA.
Musk revealed the launch date and payload over the weekend: 60 Starlink satellites, weighing around 13,000 kg (28,700 lb) ingeniously flat-packed away like an IKEA warehouse:
What we see here is completely unprecedented – no satellite-dispenser system, an incredible density of satellites, and all done privately.
What we know:
- This is SpaceX’s Starlink “v0.9” launch, an initial mid to large-scale test of its satellite system aiming to deliver broadband internet from orbit in space.
- The above image shows the Falcon fairing – thought to be the Falcon 9 – which is 13 meters or 42.6 ft high. (Or, about six Shaq’s standing on top of each other)
- 60 satellites sounds like a lot, but SpaceX is aiming for nearly 12,000 spacecrafts that will sit in a low Earth orbit.
- The FCC approved one “constellation” of 4,409 satellites, followed by a second constellation of 7,518.
- (As of March 31, the total number of operating satellites in low Earth orbit was 1,338.)
- These 60 satellites won’t be offering any commercial internet just yet – lacking a critical laser optical interlink that will transmit data between orbiting satellites in each Starlink constellation.
- So far, SpaceX has only launched two Starlink satellites for testing, called TinTin A and TinTin B, which have been in space since February 2018.
- SpaceX isn’t the only player in this game. OneWeb launched six test satellites in February of this year for its own constellation, which is set at 650-satellites.
- Telesat, LeoSat, Facebook, and Amazon most recently announced their own plans – Amazon wants to launch 3,236 sats as part of Project Kuiper.
- Here’s a helpful video explainer for Starlink after a round of changes made to initial plans in November (YouTube).
What Musk is tweeting:
- “Much will likely go wrong on 1st mission. Also, 6 more launches of 60 sats needed for minor coverage, 12 for moderate.” (meaning providing internet coverage to a particular region)
- “More details on day of launch, currently tracking to Wednesday [15th]”
- And because it’s ol’ Musky, of course there’s a 420 joke tweet.
