Starlink Signals Can Be
Reverse-Engineered to Work Like GPS—Whether SpaceX Likes it or Not
(Source: MIT Technology Review)
Todd Humphreys’s offer to SpaceX was simple. With a few software
tweaks, the Starlink constellation could also offer precise position,
navigation, and timing. The US Army, which funds Humphreys’s work,
wanted a backup to its venerable, and vulnerable, GPS system. Could
Starlink fill that role? When the idea was first proposed in 2020,
executives at SpaceX were open to the idea, says Humphreys. Then word
came from on high. “Elon told the leaders we spoke to: every other LEO
communications network has gone into bankruptcy,” Humphreys said. “And
so we have to focus completely on staying out of bankruptcy. We cannot
afford any distractions.”
But Humphreys wouldn’t take no for an answer. For the past two years,
his team at UT Austin’s Radionavigation Lab has been
reverse-engineering signals sent from thousands of Starlink internet
satellites in low Earth orbit to ground-based receivers. Now Humphreys
says his team has cracked the problem, and he believes that regular
beacon signals from the constellation, designed to help receivers
connect with the satellites, could form the basis of a useful
navigation system. Crucially, this could be done without any help from
SpaceX at all.
“The Starlink system signal is a closely guarded secret,” says
Humphreys. “Even in our early discussions, when SpaceX was being more
cooperative, they didn’t reveal any of the signal structure to us. We
had to start from scratch, building basically a little radio telescope
to eavesdrop on their signals.” To get the project started, UT Austin
acquired a Starlink terminal and used it to stream high-definition
tennis videos of Rafael Nadal from YouTube. This provided a constant
source of Starlink signals that a separate nearby antenna could listen
in on. (10/21)
U.S. Space Command to Transfer Space
Object Tracking to Department of Commerce (Source: DoD)
Right now, U.S. Space Command tracks more than 47,000 objects in space.
But there are plans to transfer that responsibility to the Department
of Commerce, an effort that will allow Spacecom to focus more on what's
happening in space rather than just on the tracking of objects there,
the Spacecom commander said.
"Operationally our allies and partners are increasing their investments
in [space domain awareness], offering enhanced capabilities that can
augment U.S. Space Command's globally-distributed sensor network,"
Dickinson said. "We must find innovative ways to create an integrated
sensor network on a global scale. Through an integrated network we can
build knowledge of the environment. Through knowledge, we know we can
gain better wisdom." (10/21)

Space Tourism Experiments Could Add To
Mankind’s Knowledge Bank. Don’t Poo Poo The Movement Just Yet
(Source: Forbes)
As with anything reaching pop-culture status, there are naysayers. They
poo poo the space tourism movement as a waste of money, something only
the rich can do, that it contributes to pollution in the atmosphere,
and more. They say that wealthy participants do nothing more than sit
in a big tin can for 11 minutes, just to brag that they’ve been to
space - defined by NASA as 50 miles above Earth - when they return.
One way to dampen this kind of criticism is by trying to do something
that contributes to the knowledge bank of mankind, perhaps conduct an
experiment or two up there, as Shift4 Payments billionaire Jared
Isaacman plans to do on his three upcoming SpaceX Polaris orbital
missions. Isaacman wants to test a new, less-cumbersome space suit on
an EVA (spacewalk), and head out to the far reaches of the Van Allen
Belt, quite a bit higher than ISS, to test the effects of radiation on
the crew and delicate electronic equipment in preparation for future
trips to Mars.
Naysayers or not, one can’t argue that valuable information about the
human psyche and hard-core science can be gleaned from private
spaceflight, including the space tourism element. Bottomline, maybe we
as a society should be more positive than negative, embrace rather than
denigrate, new developments such as private spaceflight and space
tourism. Maybe Isaacman and O’Brien have the right idea with their
experiments. (10/21)
Chang'e-5 Samples Reveal How Volcanism
Takes Place on Moon (Source: Xinhua)
A Chinese group analyzed lunar samples returned by China's Chang'e-5
mission and proposed a new mechanism for how young volcanos took shape
on the cooling moon 2 billion years ago. Scientists previously
speculated that the elevated water content or radioactive elements in
the lunar interior might have driven volcanism in the late stage of the
moon's life. But the Chang'e-5 data found its mantle source region both
dry and lacking in heat-producing substance. The study showed that the
mantle melting-point depression due to the presence of fusible,
easily-melted components could generate young lunar volcanism. (10/22)
Hale Urges More Transparency in
Artemis Commercial Contracts (Source: Space Policy Online)
The chairman of a NASA advisory committee, Wayne Hale, is urging NASA
to avoid contracts that prevent release of information to the public
because companies claim it as proprietary. That applies particularly to
Public-Private Partnerships like the Human Landing Systems being
developed for the Artemis program to return astronauts to the
Moon. In a discussion with the Aeronautics and Space Engineering Board
(ASEB) yesterday, Hale urged them “to encourage NASA not to get tied up
in proprietary contracts where they can’t release all the details”
because the “taxpayers have a stake and need to know.” (10/21)
Take the Handcuffs Off the US Space
Force (Source: The Hill)
The Heritage Foundation recently published its “Executive Summary of
the 2023 Index of U.S. Military Strength,” an annual report put out by
the foundation to “gauge the U.S. military’s ability to perform its
mission in today’s world.” In it, there is reference to the newly
formed United States Space Force asserting there is “little evidence it
has improved its readiness to provide nearly real-time support to
operational and tactical lees of force operations or that it is ready
in any way to execute defensive and offensive counterspace operations
to the degree envisioned by Congress.” Let’s examine the impacts
of this statement.
If the USSF is not successful in its ability to contest space, the
other branches of the armed forces will struggle to meet military
objectives against an adversary capable of using space-enabled weapons
for targeting or other purposes. All other military services and
their respective operations rely on the use of the space domain.
Without freedom of action to move in and through space, those
operations effectiveness become greatly challenged. One only need look
at the effectiveness of commercial space in supporting Ukrainian
command and control mission to determine how necessary space-based
capabilities are. These are the types of capabilities the USSF
deliver to ensure other military services can accomplish their
objectives.
The budget and personnel need to be adjusted due to the criticality of
the USSF mission. Because the success of the USSF is critical to the
joint fight, it is noteworthy that it is only given about 2.5 percent
of the Department of Defense budget. Congress needs to examine whether
this amount can provide the necessary systems the USSF will need to
accomplish their assigned tasks. (10/21)
Space Force to Award Up to $50 Million
in Contracts for Space Test Program Experiments (Source: Space
News)
The Space Force is changing its approach to buying satellites for the
Space Test Program, which for decades has launched experiments for the
U.S. government and allies. Instead of awarding separate contracts for
STP missions, the Space Force will select a group of vendors that will
compete for $50 million worth of task orders under a five-year
indefinite delivery/indefinite quantity (IDIQ) contract.
The plan is to select a mix of vendors that can produce spacecraft
ranging from 12U cubesats to 180-kilogram ESPA-class satellites. These
contractors will be responsible to design, develop and manufacture the
spacecraft, integrate experimental payloads, test the integrated space
vehicle, support the launch and post-launch mission operations. (10/21)

Dassault Aviation's Florida Expansion
Joins 5 Other Aerospace Projects (Source: Orlando Business
Journal)
The secret is out. Space Florida this year has been negotiating with a
company known only as "Project Vista" on a potential expansion to the
Sunshine State. Project Vista on Oct. 17 revealed itself as French
aircraft manufacturer Dassault Aviation. The maker of military and
civilian aircraft plans to invest $115 million to build a
175,000-square-foot maintenance facility in Melbourne, creating 400
high-wage jobs in the process.
Why this story matters: Statewide spaceport development authority Space
Florida is in negotiations with multiple companies to bring
construction, manufacturing and launch projects to Central Florida.
These projects stand to create jobs in the region, and most of those
jobs will pay wages higher than the regional average. If that facility
materializes as planned, it may open as soon as 2024. It's a big win
for the region — and it's not the only jobs-generating project Space
Florida aims to lure there.
New projects only would add to the Space Coast's identity as a
high-wage aerospace hub. The region is home to NASA's Kennedy Space
Center and Cape Canaveral Air Force Station, and it's home to launch
and manufacturing operations of space companies like SpaceX, Boeing,
Blue Origin, and Lockheed Martin. This concentration of aviation and
aerospace employers in Brevard County means a hub of skilled workers,
which is one of the main reasons Dassault Aviation picked the area for
its biggest U.S. investment in company history, Chairman and CEO Eric
Trappier said in a prepared statement. (10/21)
