in August 2022, SpaceX made formal regulatory filings with the FCC that indicated they would build satellites of the second-generation (Gen2) constellation in two different, but technically identical, form factors: one with the physical structures tailored to launching on Falcon 9, and one tailored for the launching on Starship.[101][252] Starlink v2.0 is both larger and heavier than Starlink v1 satellites.[citation needed]
Starlink second-generation satellites planned for launch on Starship have the following characteristics:[253][252]
Lasers for inter-satellite communication[254]
Mass: ∼1,250 kg (2,760 lb)
Length: ∼7 m (23 ft)
Further improvements to reduce its brightness, including the use of a dielectric mirror film.[255]
On 2,016 of the initially licensed 7,500 satellites[256]: Gen2 Starlink satellites will also include an approximately 25 square meter antenna that would allow T-Mobile subscribers to be able to communicate directly via satellite through their regular mobile devices.[101] It will be implemented via a German-licensed hosted payload developed together with SpaceX's subsidiary Swarm Technologies and T-Mobile.[256] This hardware is supplemental to the existing Ku-band and Ka-band systems, and inter-satellite laser links, that have been on the first generation satellites launching as of mid-2022.[citation needed]
Further, in late December 2022, SpaceX redefined some early v2.0s so there are 3 different busses of v2.0s:
- Bus F9-1, 303 kg mass, having roughly the same dimensions and mass as the current V1.5 satellites
- Bus F9-2 (sometimes called "V2 mini"[101]), 800 kg mass and measuring 4.1 m (13 ft) by 2.7 m (8 ft 10 in) with a total array of 120 m2 (1,300 sq ft). It could offer around 3-4 times more usable bandwidth per satellite.[257]
- Bus Starship, 2000 kg mass being the original v2.0 satellites[258]
