SpaceX Unveils 'V2 Mini' Starlink Satellites With Quadruple the Capacity (arstechnica.com) 89
An anonymous reader quotes a report from Ars Technica: With Starlink speeds slowing due to a growing capacity crunch, SpaceX said a launch happening as soon as today will deploy the first "V2 Mini" satellites that provide four times more per-satellite capacity than earlier versions. Starlink's second-generation satellites include the V2 Minis and the larger V2. The larger V2s are designed for the SpaceX Starship, which isn't quite ready to launch yet, but the V2 Minis are slimmed-down versions that can be deployed from the Falcon 9 rocket. "The V2 Minis are smaller than the V2 satellites (hence the name) but don't let the name fool you," SpaceX said in a statement provided to Ars yesterday. "The V2 Minis include more advanced phased array antennas and the use of E-band for backhaul, which will enable Starlink to provide ~4x more capacity per satellite than earlier iterations."
SpaceX didn't specify the amount of data that each V2 Mini satellite can provide, but its first-generation satellites were designed for an aggregate downlink capacity of 17 to 23Gbps per satellite. The Federal Communications Commission recently gave SpaceX approval to launch 7,500 of the 30,000 planned second-generation satellites. A SpaceX Falcon 9 launch tentatively scheduled for today would put 21 V2 Minis into orbit. The larger V2 satellites that can't launch until Starship is ready will be able to send signals directly to cell phones, a capability that'll be used by SpaceX and T-Mobile in a partnership announced in August 2022. "Each Starlink V2 Mini satellite weighs about 1,760 pounds (800 kilograms) at launch, nearly three times heavier than the older Starlink satellites," notes Spaceflight Now. "They are also bigger in size, with a spacecraft body more than 13 feet (4.1 meters) wide, filling more of the Falcon 9 rocket's payload fairing during launch."
UPDATE: SpaceX successfully launched the first batch of "V2 Mini" Starlink satellites. "A Falcon 9 rocket hauled the 21 Starlink satellites into a 230-mile-high (370-kilometer) orbit after lifting off from pad 40 at Cape Canaveral Space Force Station at 6:13:50 p.m. EST (2313:50 GMT) Monday," reports Spaceflight Now. "SpaceX delayed the launch from earlier Monday afternoon to wait for radiation levels to abate following a solar storm that sparked dramatic auroral displays visible across Northern Europe and Canada." You can watch the launch here. Elon Musk also shared video of the first V2 satellites to reach orbit.

SpaceX can't just let them go into an uncontrolled de-orbit. They have to keep enough fuel available to de-orbit them through the orbits of other satellites in a safe manner. How well that works is unproven as the satellites haven't been up long enough to see what the effect of de-orbiting thousands a year is. Other operators have already had to take action to avoid collisions with Starlink satellites on the way up, and the system for notifying other orgs isn't really designed for thousands of notifications

Yes, they can and do let them de-orbit uncontrolled. When at end of life, they lower them to a low orbit then passivate them, shut them down, and let them re-enter within, I think, a week. They can do this because everything in the satellites breaks down into either very light items, dust, or gas, so it isn't an issue if they re-enter over an inhabited location.
Re: (Score:1)
You are confirming what I said. They lower them until they are ready to de-orbit, which means passing through the orbits of many other satellites on the way.
Since the exact composition of the satellites is secret it's hard to predict exactly what effect that gas and dust will have. Generally speaking the effect of releasing stuff into the upper atmosphere is magnified compared to releasing it at ground level, hence why aircraft contribute so much to climate change.

It certainly can happen at the altitudes that Starlink operates at.
