Droids for Space? Startup Plans Satellites With Robotic Arms For Repairs and Collecting Space Junk
“Imagine if every car we ever created was just left on the road,” said aerospace entrepreneur Jeromy Grimmett. “That’s what we’re doing in space.” Grimmett’s tiny company, Rogue Space Systems Corp., has devised a daring solution. It’s building “orbots” — satellites with robotic arms that can fly right up to a disabled satellite and fix it. Or these orbots could use their arms to collect orbiting rubble left behind by hundreds of previous launches — dangerous junk that’s become a hazard to celestial navigation…
Rogue Space aims to catch up fast, with help from Small Business Technology Transfer funds from the SpaceWERX Orbital Prime initiative. Created by the U.S. Space Force, Orbital Prime seeks to build up U.S. private-sector firms that can protect national security by maintaining military satellites and clearing hazardous space debris.
Its first 10-pound, proof-of-concept satellite will launch later this year, the article points out, “to test sensors and software to confirm the system can identify and track other satellites.” But “the real excitement will begin later this year” when the company launches a prototype that’s four times larger that will “use maneuvering thrusters to test the extremely precise navigation needed to approach a satellite.”
And then in late 2024 or early 2025 the company will launch its 660-pound satellite “with robotic arms for fixing other satellites or for dragging debris to a lower orbit, where it will fall back to Earth.”

SpaceX’s Next-Gen Starlink Satellites Have Started Falling From Space
It’s been a little over a month since SpaceX launched 21 mini versions of its next-generation Starlink satellites, but it appears that one of those little guys just couldn’t cling to orbit any longer.
OneWeb Has Given Up on Trying to Get Its Hijacked Satellites Back From Russia
British satellite company OneWeb is counting its losses, and not its satellites. Following a fallout with the Russian space agency that led to 36 of its satellites being held captive in Kazakhstan, a company official said that they have “moved on.”
FCC proposal would make it easier for smartphones to link to satellites
Satellite-to-phone service is only just getting started, and the Federal Communications Commission (FCC) wants to give a boost. The regulator is proposing rules that would make it easier for phone carriers and satellite operators to provide coverage in remote and underserved areas. Under the plan, satellite companies teaming with cellular providers could get FCC permission to operate on some licensed, flexible wireless spectrum normally reserved for ground-based service.
Operators would have to meet certain requirements. They’d have to use non-geostationary orbit satellites, and get leases from terrestrial spectrum owners in a given area. After that, though, they could provide outdoor service even in areas where cellphones are completely non-functional.
Few devices support satellite connections so far. Apple’s iPhone 14 family can use satellites to send emergency messages. Qualcomm’s Snapdragon Satellite enables texting off the grid, but only for Android phones using Snapdragon systems-on-chip and the X70 modem. It won’t arrive until the second half of 2023, however. Carrier partnerships also won’t kick off in earnest until T-Mobile and SpaceX roll out their Starlink-based collaboration. Testing for that begins later this year, although it should work with both standard texting as well as some messaging apps.
The technology usually depends on line of sight to a satellite, and the limited bandwidth of existing solutions makes them impractical for significant data transfers. However, they can help you reach first responders during a hike or confirm your arrival at a camp site in the wilderness. Eventually, the hope is to use satellites for general data.
The FCC is looking for public input on how the satellite-to-cell rules would bolster access to 911 and Wireless Emergency Alerts. The agency is also exploring whether or not it can apply the framework to other purposes, regions and wireless bands. If the proposal moves ahead, though, carriers beyond T-Mobile may have a relatively easy time filling (some) gaps in their networks.

Satellites like SpaceX’s Starlink are disrupting Hubble observations
Satellites Show Turkey/Syria Earthquake Opened Massive 300km Fissure
Researchers from the U.K. Centre for the Observation & Modelling of Earthquakes, Volcanoes & Tectonics (COMET) found the ruptures by comparing images of the area near the Mediterranean Sea coast taken by the European Earth-observing satellite Sentinel-1 before and after the devastating earthquakes. The longer of the two ruptures stretches 190 miles (300 kilometers) in the northeastern direction from the northeastern tip of the Mediterranean Sea. The crack was created by the first of the two major tremors that hit the region on Monday, the more powerful 7.8-magnitude earthquake that struck at 4:17 a.m. local time (8:17 p.m. EST on Feb. 5). The second crack, 80 miles long (125 km), opened during the second, somewhat milder 7.5-magnitude temblor about nine hours
“This earthquake fault is one of the longest on record on the continents,” the team’s leader told Space.com, adding that it was “very unusual to have two such large earthquakes happening within a few hours of each other.”

Amazon Scores FCC Approval to Deploy Over 3,000 Broadband Satellites
The Federal Communications Commission has granted approval to Amazon subsidiary Kuiper Systems to deploy its constellation of 3,236 broadband satellites. The approval comes with the caveat that Amazon must retire satellites seven years after deployment and report satellite launches to the FCC on a regular basis.
