Update on #ProjectKuiper

1/ Here’s an update to my roundup of @amazon ‘s gigantic tranche of 94 launch contracts for its #ProjectKuiper satellite constellation 

2/ As of June 2023, no satellites are in orbit and Amazon has just 37 months to launch 1/2 the constellation under its spectrum license 

3/ The first two are scheduled to fly on the ULAVulcan debut launch delayed until Q4 2023 

4/ Here's an updated graphic showing the number of months remaining

 
5/ Only @SpaceX has launched a comparable number of satellites with TBD #starlink in LEO 

6/ It took @SpaceX 24 months & TBD launches to surpass 1600 in orbit

7/ Prior to lofting the #StarLink constellation, #Falcon9 had completed a total of TBD launches including #TBD in preceeding 12 months 

8/ As of this writing, the only launch vehicle in the #Amazon fleet to reach orbit is the #ULAAtlasV 

9/ None of the new heavy launch vehicles #HLV is yet flying - #ULAVulcan & #Ariane6 debut launches are delayed to Q4 2023 & could easily slip into 2024 Vulcan debut Q4 operational NET June 2024 https://arstechnica.com/space/2023/06/ula-shipping-vulcan-upper-stage-back-to-factory-for-more-work/  

10/ #NewGlenn has no public goal for a debut flight 

11/ All three new #HLV rely on new engines 

12/ NewGlenn & ULA Vulcan use #BlueOrigin #BE4-4 engines & only two #BE4 engines have been seen in public 

13/ The #ESA #Vulcain engines are upgrades to v2 that have been in development for years 

14/ Two (2) #BE4s are required to for each #ULAVulcan & seven (7) for each #NewGlenn 

15/ So #ProjectKuiper will require 38*2=76 + 12*7 = 160 or a total of 236 #BE4s as none of these vehicles are yet reusable

The "Google Maps effect"

Are you experiencing the "Google Maps effect?”  That's the reality whereby we all drive places listening to our phones spoken directions but have no idea where we are because we never looked at the map.

Read FastCompany - Why every founder's first hire should be a product marketer The first sentence is the key point: "As an early stage tech founder, you have one goal: Show product-market fit (PMF) as fast as possible. That’s it." Exactly right! Without PMF, every dollar you spend on development, marketing, and sales is wasted. And everyone's time is wasted. Why? Because until you can prove PMF, you don't know what sells . . .you are trusting your gut . . .and the odds are that you are wrong. Which is why you need to hire and listen to a Product Marketer: "As a seed-stage founder, you need to surround yourself with leaders unafraid to question everything. PMMs are no exception. They’re highly critical people by nature; they see the bigger picture and question assumptions. Because product marketers can readily distinguish a viable reality from a lofty aspiration, they’re not “yes people.” And your startup is better for it." Read the full article here: ht
