FCC Approves Giant Mirror Satellite
Designed To Beam Sunlight to Earth After Dark (Source: TechSpot)
Remember the California startup that was developing a constellation of
satellites with giant Mylar mirrors to beam sunlight back to Earth
after dark? Despite the plan generating a slew of controversy, those
satellites have passed another hurdle toward becoming a reality after
the FCC approved them.
Back in July 2025, Reflect Orbital submitted an application to launch
EƤrendil-1, a demonstration satellite designed to test whether sunlight
can be redirected from orbit onto specific locations on Earth. The FCC
has now granted the satellite permission to operate its radio
equipment. The regulator also rejected calls to block the project over
its enormous reflective surface, arguing that the mirror itself falls
outside the FCC's authority because the agency primarily regulates
communications spectrum. (7/10)
Taffing the Moon Base: How Many
Astronauts Should Live in NASA’s Lunar Outpost? (Source:
Space.com)
The success of NASA's future moon base depends in large part on mission
design, which should allow astronauts to work together well in a way
independent from psychological training, a new study asserts. The goal
of the study was to identify "specific conditions" for mission success
and to look for any "red flags" that may stand in the way, said lead
investigator Anamaria Berea. The study team considered scenarios for
how many astronauts would be on the moon base and how often resupply
missions would occur.
In an "initial case," for example, the assumed mission duration was
three months, with a single resupply run at Month 2 with food, water,
air and a fresh group of astronauts. Using a complex probability
analysis known as a Monte Carlo simulation, the model astronauts in
this scenario showed a productivity rate of about 20% against their
expected tasks, "which is acceptable for a typical manufacturing
process," the authors noted. "The worst-case scenario consists of four
astronauts on the moon at one time, only one month resupply window
between Earth and moon, and moderate to high adverse environmental
probabilities."
NASA tracks productivity a little differently on the International
Space Station (ISS). The agency uses a metric called "utilization,"
which largely refers to the amount of crew time and number of
scientific investigations that are performed on the space station
during an increment or expedition. As of 2014, the ISS program
suggested that ideal utilization should be 35 hours per crew per week
when there are three people working on the U.S. part of the space
station, and 68.5 hours if there are four or more. (The Russian side of
the ISS works largely independently in this respect.) (7/8)
Huge Galactic Structure Is 23 Million
Light-Years Long, And We Can't Comprehend It (Source: Science
Alert)
There are plenty of mind-bendingly large structures in our Universe.
But when it comes to galaxies, two discoveries over the past five years
have given the word 'massive' a whole new meaning. Case in point, one
of the biggest structures of galactic origin detected by humans in
radio waves: Porphyrion.
Named after the king of giants in Greek mythology, Porphyrion is 7.5
billion light-years away, so it's not exactly in our galactic
neighborhood. It was first detected in 2024, when researchers picked up
radio signals from a pair of jets being blasted out by the black hole
presumably at the galaxy's center. (7/11)
US’ New Weapon Can Blast Enemy
Satellites with Beams of Electromagnetic Radiation (Source:
Interesting Engineering)
The U.S. Space Force has got a new capability to make enemy satellites
almost inactive and disrupt their signals without physically damaging
them. Meadowlands is a critical upgrade to the Counter Communications
System (CCS) 10.2 and it can detect, deny, disrupt, and degrade
adversary’s use of the electromagnetic spectrum — such as radio waves.
The electromagnetic warfare’s system reversible and non-reversible
capabilities further secures the invisible frontline on the

The EU Wants to Control Your Speed Via
Satellite (Source: The Drive)
It has been a wild couple of weeks for the Big Brother news beat—wild
enough that a particularly alarming item managed to slip beneath just
about everybody‘s radar. According to the Daily Mail, the European
Commission wants the power to force cars to obey speed limits with help
from GPS.
European cars already leave the factory with speed monitoring systems
installed, and no, I don’t just mean speedometers. Starting in 2024,
the EU mandated that all new cars come equipped with a GPS-based system
that tracks the current speed limit and alerts the driver audibly if it
is exceeded. These “Intelligent Speed Assist” systems are often
installed on cars sold outside the EU as well, though the warning
component is often optional or disabled. (7/9)
We Should Establish an Inland
Spaceport in the American West (Source: Christian Keil)
All US spaceports today are coastal — meaning they're within ~12
nautical miles of international waters, or <60 seconds downrange for
a ship/sub-based missile. In peacetime, this allows for easy
surveillance, both of national security rocket launches and the sites
themselves. But in wartime our launch sites might not survive the first
minute of a major conflict.
Part 1 of the solution is to do what China has done: establish inland
launch sites that are further from international borders and therefore
easier to defend. Part 2 of the solution is to do the *opposite* of
what China has done: America should not fly experimental missions over
land, or drop rockets full of hypergolic fuel onto rural villages.
Inland launch sites should only be used for reusable rockets that have
a track record of success.
America needs a launch pad in Utah, Nevada, Wyoming, or Montana, and
landing pads ~500 km north and/or east. We already have similar
infrastructure that exists today (White Sands, UTTR, NTTR, Spaceport
America). Adding one more such site would secure our access to space
even on a very bad day. (7/9)

Scientists Say Some Black Holes Are
Born From Other Black Holes (Source: Gizmodo)
Since LIGO’s Nobel-winning discovery of gravitational waves—ripples in
spacetime—the U.S.-based detector has been picking up on hundreds of
signals from black hole mergers. And, after a decade of studying
gravitational waves, researchers believe a significant fraction of
black holes may come from cosmic chain reactions.
A recent paper describes an analysis of 155 pairs of binary black
holes, identified by LIGO and its sisters, Virgo and KAGRA, in Italy
and Japan, respectively. According to the study, about 14% of merging
black holes may be what’s called “second-generation black holes,” or
black holes that form from previous mergers of two smaller black holes.
This “hierarchical” backstory is vastly different from the textbook
version of how black holes emerge from the explosive death of a star.

Democratic Texas AG Candidate Claims
$110m in Gants for Elon Musk’s Starlink ‘sure Looks’ Like Corruption
(Source: The Guardian)
The Texas Democrat nominee to become the state’s attorney general has
said he will investigate SpaceX if elected, saying it “sure looks like”
corruption was involved in a deal he said handed the world’s richest
person $110 million of taxpayers’ money dedicated to providing internet
access in remote areas. Nathan Johnson called for greater legislative
scrutiny of state grants funneled to SpaceX for its Starlink satellite
program. He said the award by Texas Republicans of 99% of the available
grant funds to a company led by billionaire Musk, a Donald Trump ally,
was lopsided.
“I am not declaring that corruption was at work in this instance. I am
saying that it sure looks like it,” Johnson, a state senator, told the
Dallas News. “Public confidence in the bidding process has been
undermined.” During his primary campaign, Johnson promised to overhaul
the office of the Texas attorney general, a position currently held by
Ken Paxton, the scandal-ridden hardline Republican recently nominated
by his party to run for the US Senate in November’s midterms.
He has said he will work closely with the state comptroller to audit
how government contracts are awarded. The Starlink grants, signed off
by the Republican Texas governor, Greg Abbott, after his office
reportedly revised rules to favor low-Earth-orbit satellite providers
in bids to provide rural internet access, have become a particular
source of controversy. (7/10)

NASA Sure Seems to be Asking an Awful
Lot of Private Space Stations (Source: Ars Technica)
So what do the private companies—the key players are Axiom Space, Vast
Space, Voyager, Blue Origin, and possibly SpaceX—think about the new
document? There are two main feelings: relief and concern. The relief
is easy to explain. A government-sponsored core module was widely
disliked and seen as an effort by NASA JSC, which operates the ISS, to
remain in the business of operating a space station. Now that worry is
gone.
But there are multiple reasons for concern. One is lost time. The
private companies expected phase two to begin at least a year or two
ago, and they are struggling to raise funding and support growing
workforces in the interim. NASA rules for human safety in orbit will
drive the designs the private companies ultimately build. So companies
really need to know exactly what NASA wants, and how much it is willing
to pay to move forward. (7/10)

Volatility is the name of the game when it comes to SpaceX stock. Only
a small amount of SpaceX stock is available for public trading, making
the shares susceptible to big swings as insiders remain subject to
