Satellite operators want option to exceed deorbiting rules

(2022/09/22)


A group of satellite operators has asked the Federal Communications Commission (FCC) to reconsider its proposed five-year window to remove orbital junk by adding language that would let them request waivers to exceed the limit.

Iridium Communications, HughesNet operator EchoStar, Luxembourg-based SES, and OneWeb, currently building a satellite constellation it said will provide global broadband, penned [1]the letter [PDF] earlier this week. The group asked that the FCC "adopt explicit language recognizing that operators may seek and obtain waivers of the five-year post-mission disposal rule for good cause," as well as establish "objective criteria" for evaluating waiver requests.

The FCC proposed its new rule, which would reduce the period space operators have to remove retired equipment from low-Earth orbit (LEO, defined as below 2,000 kilometers) from 25 years to five, [2]earlier this month in a bid to clear up the increasingly crowded space surrounding Earth.

FCC chairwoman Jessica Rosenworcel [4]said of the proposal that it was necessary to support the rapidly growing space economy. "Satellites can stay in orbit for decades, careening around our increasingly crowded skies as space junk and raising the risk of collisions that can ruin satellites we count on," Rosenworcel said.

As noted in previous coverage, the FCC said there were more than 4,800 satellites in orbit of Earth at the end of 2021, with most of those flitting about in LEO. Per the FCC, many of those satellites were launched in the last two years "and projections for future growth suggest that there are many more to come."

In August, the FCC voted to open proceedings on in-space servicing, assembly and manufacturing, or [11]ISAM , which would see some industrial processes moved to Earth orbit to hopefully protect the environment and mitigate climate change.

Rosenworcel [12]said that space debris could be removed by ISAM operations, but FCC commissioner Nathan Simington expressed concern that space debris could impact ISAM operations by damaging equipment. Simington [13]said in a statement that the FCC was considering updating its space debris rules.

Aside from the threat of falling space junk to cities and people, an overabundance of satellites in Earth's orbit has also affected astronomers, who said there is so much orbital hardware that [14]Starlink satellites appear in around a fifth of images snapped by some telescopes. AI algorithms have been developed to fight this, but have [15]only proven to be so effective .

[16]

SpaceX's second generation of Starlink satellites are designed to minimize light pollution on Earth, but until the Musk-owned company can [17]get its Starship off the ground , it won't be able to launch the new hardware.

The FCC is expected to vote on the five-year proposal on September 29. Whether a waiver option will be added remains to be seen; so far the FCC hasn't responded to our questions asking such. ®

Granted!

Bartholomew

I would grant them their option to exceed deorbiting rules as long as their satellite is at or below an orbit of 550 km

( [1] It takes about 5 years for debris at 550 km to naturally deorbit due to atmospheric drag (depending on mass and surface area, amount of X-rays from the sun absorbed and warming the thermosphere, oh and disturbances to earths magnetic field ). So to stay in orbit they would need to use fuel, and once their fuel is gone they will deorbit in about 5 years *evil grin*). Once you get to 2000 km natural deorbit takes about 20 thousand years, and higher than the Exosphere (10,000 km) there is no atmospheric drag and the objects will never de-orbit. Most GPS satellites orbit roughly above about 20,000 km.

Allow a waiver with a couple of conditions: 1. You can't replace it until it's down and 2. You're on the hook for any collisions it's involved in while in orbit.

Anonymous Coward

Being "on the hook" for collisions is fairly meaningless. The concern isn't that a collision costs money, but that it snowballs quickly to the point where the earth is surrounded by 1mm bits of metal orbiting at 15000mph and obliterating anything we ever try and launch again. If that happens it doesn't matter who is "on the hook for it", it brings an end to any goals we have in space.

Claptrap314

We've got a LONG ways to go before that's a real problem, however.

Far more problematic is a business doing a default & restructure to avoid liability. You would want a bond--but there are issues with the insurance industry as well.

Doctor Syntax

An obligation to insure is what I had in mind. And, of course, the premium would have to be large to take into account the collateral damage due to the fragmentation the A/C mentions. IOW, make it preferable to get an unusable satellite down. Why leave it there?

batshit crazy idea

brainwrong

Build large scale solar powered electrolysis plants to produce hydrogen gas to vent into the atmosphere. It will rise to the top of the atmosphere and provide drag on all orbiting objects on its journey to space. It'll bring all stuff down quicker, and maybe reduce sea levels to boot.

May need a big, well enforced no-smoking zone :)

Starlink V2 can launch on Falcon 9

FeepingCreature

Slight correction: Starlink V2 can probably be launched on F9 with some adjustments, at least according to an FCC filing: https://forum.nasaspaceflight.com/index.php?topic=46726.msg2398259#msg2398259

They'll probably only really be economic with Starship though.

Make headway at work. Continue to let things deteriorate at home.
