Developing Design Tools for Outer
Space Structures (Source: Space Daily)
Achieving affordable space exploration will require lightweight
structures for vehicles, solar arrays and antennas. Lightweight
materials also will be used for components of structures like
pressurized habitats, cryogenic tanks, landing gears and truss cages.
The problem is that NASA envisions that many of those structures will
be made from tailorable composite materials, but no design tool has
been able to fully exploit the materials' full potential. AnalySwift
LLC, a Purdue University-affiliated commercial software provider, and
Wenbin Yu, a professor in Purdue's School of Aeronautics and
Astronautics, are conducting research to create one.
Existing design tools were developed for traditional composites, which
have straight fibers. If an open area is needed inside a traditional
composite structure, this is often accomplished by creating a cut-out
after it is manufactured, which can compromise the integrity of the
structure. "Tailorable composites, also known as tow-steered or
variable thickness composites, however, can be highly customized thanks
to improvements in manufacturing," he said. "New robotic techniques can
weave fibers around areas intended for openings, expanding design
options while improving the structures' overall properties."
AnalySwift has received a one-year, $125,000 Phase I STTR contract from
NASA for a project titled "An Efficient, High-Fidelity Design Tool for
Advanced Tailorable Composites." Yu said the project will benefit
NASA and related agencies and industries by exploiting the potential of
tailorable composites for designing better lightweight structures. "The
resulting efficient, high-fidelity design tool developed in this
project will shorten the design and analysis period of structures made
of tailorable composites," Yu said. (3/17)
Poland Signs with Virgin Orbit for
Domestic Launch Services (Source: Space Daily)
In an official letter of intent with the leading responsive space
company Virgin Orbit (Nasdaq: VORB), the Polish Space Agency (POLSA),
the agency overseeing Poland's space development, conveyed its strong
interest in bringing a domestic launch capability to Poland, a
development uniquely made possible through Virgin Orbit's air-launched
LauncherOne system. The signed letter codifies the Polish government's
intent to collaborate with Virgin Orbit to conduct a detailed analysis
of LauncherOne's practical applications in support of Poland's science
and economy industries. (3/18)
Space Force Preparing to Decommission
Legacy Command and Control System (Source: C4ISRnet)
By the end of this year, the Space Force hopes to have fully
transitioned from its legacy space catalog system to a modernized
command and control capability — a milestone years in the making.
The service is in the process of decommissioning the Space Defense
Operations Center (SPADOC), which was fielded in 1979, and replacing it
with the new Space Command-and-Control (Space C2) system that will
bring together operational-level C2 capabilities into one integrated
system. Along with developing an enterprise infrastructure, the program
will deliver applications to decision-making hubs — like the National
Space Defense Center, Combined Space Operations Center and the 18th
Space Control Squadron – that will help process data from ground- and
space-based sensors. (3/16)
Moon's Orbit Proposed as a
Gravitational Wave Detector (Source: Space Daily)
Researchers propose using the variations in distance between the Earth
and the Moon, which can be measured with a precision of less than a
centimeter, as a new gravitational wave detector within a frequency
range that current devices cannot detect. The research, which could
pave the way for the detection of signals from the early universe, was
published recently in Physical Review Letters.
Gravitational waves, predicted by Albert Einstein at the start of the
20th century and detected for the first time in 2015, are the new
messengers of the most violent processes taking place in the universe.
The gravitational wave detectors scan different frequency ranges,
similar to moving a dial when tuning into a radio station. (3/18)

Lunar caves are not only a geologically pristine record of the Moon's
history, but they could also provide a safe home for future human
explorers. Building upon ESA Discovery's OSIP call and SysNova
challenge, ESA gathered a spectrum of over 60 experts in many different
areas of science and engineering to design a mission to enter a pit on
the Moon's surface and explore the entrance to a lunar cave.
The Moon is dotted with pits that scientists think could lead to huge
underground tunnels. But a space mission has never been sent to explore
what could lie within. ESA kick-started such a mission in 2019, when
the Discovery element of ESA's Basic Activities launched a public Open
Space Innovation Platform (OSIP) call for ideas to detect, map and
explore lunar caves. Five ideas were chosen to be studied in more
detail through an ESA Discovery SysNova challenge, each addressing a
different phase of a potential mission. (3/17)
