With Further Delays to BE-4 Rocket
Engine, Vulcan May Not Make 2022 Debut (Source: Ars Technica)
Blue Origin is unlikely to deliver two flight-ready versions of the
BE-4 rocket engine to United Launch Alliance (ULA) before at least the
second quarter of 2022, two sources say. This increases the possibility
that the debut flight of ULA's much-anticipated new rocket, Vulcan,
could slip into 2023. Vulcan's first stage is powered by two BE-4
engines, which burn methane and are more powerful than the space
shuttle's main engines. The sources said there recently was a
"relatively small" production issue with fabrication of the flight
engines at Blue Origin's factory in Kent, Washington.
As a result of this, the engines will not be completed and shipped to
the company's test stands in West Texas until next year. Once there,
each engine must be unpacked, tested, and then re-configured to be
moved to ULA's rocket assembly facility in northern Alabama. A
reasonable "no-earlier-than" date for the engines' arrival at the
rocket manufacturer is now April 2022, and this assumes a smooth final
production and testing phase. There is a lot riding on this rocket and
its timely debut, which will replace both the Atlas and Delta rockets
that ULA has flown.
The US military is counting on Vulcan to lift about 60 percent of the
nation's national security payloads into space from 2022 to 2027. Due
to delays in development—at one point, Vulcan rocket was expected to
debut in 2020—the US Space Force and ULA have already agreed to move
the first military mission assigned to Vulcan, designated USSF-51, onto
an Atlas 5 rocket. However, ULA has since said that all of its
remaining Atlas rockets, which are being phased out due to reliance on
the Russian-built RD-180 engine, are allocated to other missions. It is
not clear, therefore, that other military missions can be moved off of
Vulcan and onto an Atlas. (12/13)

Iron Integral to the Development of
Life on Earth - and the Possibility of Life on Other Planets
(Source: Space Daily)
Iron is an essential nutrient that almost all life requires to grow and
thrive. Iron's importance goes all the way back to the formation of the
planet Earth, where the amount of iron in the Earth's rocky mantle was
'set' by the conditions under which the planet formed and went on to
have major ramifications for how life developed.
Now, scientists at the University of Oxford have uncovered the likely
mechanisms by which iron influenced the development of complex life
forms, which can also be used to understand how likely (or unlikely)
advanced life forms might be on other planets. "Too little iron in the
rocky portion of the planet, like the planet Mercury, and life is
unlikely. Too much, like Mars, and water may be difficult to keep on
the surface for times relevant to the evolution of complex life." (12/8)
The Uneven Universe (Source:
Space Daily)
It is almost always assumed in cosmological calculations that there is
a even distribution of matter in the universe. This is because the
calculations would be much too complicated if the position of every
single star were to be included. In reality, the universe is not
uniform: in some places there are stars and planets, in others there is
just a void.
Physicists Michael te Vrugt and Prof. Raphael Wittkowski from the
Institute of Theoretical Physics and the Center for Soft Nanoscience
(SoN) at the University of Munster (Germany) have, together with
physicist Dr. Sabine Hossenfelder from the Frankfurt Institute for
Advanced Studies (FIAS; Germany), developed a new model for this
problem. Their starting point was the Mori-Zwanzig formalism, a method
for describing systems consisting of a large number of particles with a
small number of measurands. (12/6)
Gas Bubbles in Rock Pores - a Nursery
for Life on Early Earth (Source: Space Daily)
Where and how did life begin on Early Earth more than 3.5 billion years
ago from non-living chemicals? Discovering the answer to this question
has long been debated and is a challenge for scientists. One thing that
scientists can look for is potential environments that allowed life to
spark. A key necessity for the first cells on Earth is the ability to
make compartments and evolve to facilitate the first chemical
reactions. Membraneless coacervate microdroplets are excellent
candidates to describe protocells, with the ability to partition,
concentrate molecules and support biochemical reactions.
Scientists have not yet shown how those microdroplets could have
evolved to start life on earth. Researchers at LMU's Center for
NanoScience (CeNS) and the Max Planck Institute of Molecular Cell
Biology and Genetics (MPI-CBG) in Dresden now demonstrate for the first
time, that the growth and division of membraneless microdroplets is
possible in an environment which is similar to gas bubbles within a
heated rock pore on Early Earth. Suggesting that life may have had its
origin there. (12/8)
Gravitational Waves Should Permanently
Distort Space-Time (Source: Quanta)
The first detection of gravitational waves in 2016 provided decisive
confirmation of Einstein’s general theory of relativity. But another
astounding prediction remains unconfirmed: According to general
relativity, every gravitational wave should leave an indelible imprint
on the structure of space-time. It should permanently strain space,
displacing the mirrors of a gravitational wave detector even after the
wave has passed. Since that first detection almost six years ago,
physicists have been trying to figure out how to measure this so-called
“memory effect.”
“The memory effect is absolutely a strange, strange phenomenon,” said
Paul Lasky, an astrophysicist at Monash University in Australia. “It’s
really deep stuff.” Their goals are broader than just glimpsing the
permanent space-time scars left by a passing gravitational wave. By
exploring the links between matter, energy and space-time, physicists
hope to come to a better understanding of Stephen Hawking’s black hole
information paradox. (12/8)
Gravitational Waves Could be Key to
Answering Why More Matter Was Left Over After Big Bang (Source:
Space Daily)
A team of theoretical researchers have found it might be possible to
detect Q-balls in gravitational waves, and their detection would answer
why more matter than anti-matter to be left over after the Big Bang.
The reason humans exist is because at some time in the first second of
the Universe's existence, somehow more matter was produced than
anti-matter. The nature of Q-balls is a bit tricky to understand, but
they are bosons like the Higgs boson.
The asymmetry is so small that only one extra particle of matter was
produced every time ten billion particles of anti matter were produced.
The problem is that even though this asymmetry is small, current
theories of physics cannot explain it. In fact, standard theories say
matter and anti matter should have been produced in exactly equal
quantities, but the existence of humans, Earth, and everything else in
the universe proves there must be more, undiscovered physics.
Currently, a popular idea shared by researchers is that this asymmetry
was produced just after inflation, a period in the early universe when
there was a very rapid expansion. A blob of field could have stretched
out over the horizon to evolve and fragment in just the right way to
produce this asymmetry. The researchers also found the conditions to
create these ripples are very common, and the resulting gravitational
waves should be large enough, and low enough frequency to be detected
by conventional gravitational wave detectors. (12/9)
Europe Opens Up a New Space to
Commercial Services (Source: Space Daily)
From launchers and spacecraft to space habitats, private companies are
invited to join Europe's activities in Earth's orbital neighborhood and
provide services in a rocketing market. These commercial services would
overlap with the end of lifetime of the International Space Station
that is expected to stop operations most likely in the early 2030s.
"One of the major challenges for Europe is to remain relevant in low
Earth orbit, and to stay competitive amongst other spacefaring
nations," says David Parker, ESA's director of human and robotic
exploration. Cargo and human space transportation are essential
capabilities to access this new economic sphere. "We are asking
industry what Europe's role could be in providing autonomous European
space transportation services in a future without the International
Space Station," says Daniel Neuenschwander, ESA's director of space
transportation.
While investors are gaining record momentum in a diversified landscape
of emerging countries and entrepreneurs, Parker adds that "it is
crucial that Europe is not left behind and seizes every opportunity to
offer services, economic growth and innovation. ESA is preparing its
future activities in the frame of the "SciHab" (Science and Habitation)
concept - an orbital human-tended platform with a modular design and
open to commercial services. SciHab has been dubbed as the future
lighthouse for Europe's presence in Earth orbit, both a science and
habitation platform. (12/10)
Chinese Yutu-2 Rover Embarks on
Weeks-Long 80-Meter Journey to Reach 'Moon Cube' (Sources:
Sputnik, Vice)
As China's Yutu-2 lunar rover set off to investigate a peculiar shape
dubbed the "moon cube," which the craft spotted earlier this month, the
rover will take its time traveling to it. It may take about two to
three lunar days, "or two to three months on Earth," for the rover to
reach the object supposedly located about 80 meters away.
While Yutu-2 has a designed maximum speed of 200 meters per hour, in
reality, the rover does not plough ahead at full speed. Instead,
engineers on Earth calculate every step the rover takes, using
satellite images of the moon's surface and images taken by the craft's
cameras to plot its course and guide it to avoid obstacles such as
craters that dot the lunar landscape.
The craft also makes stops to conduct research, and it has to halt its
operations when it becomes too cold during the lunar night. The
complicated nature of the rover's navigation process thus results in
the rover moving "very slowly but surely," the media outlet notes,
pointing out that by the end of September, after 1,000 days of
operation, Yutu-2 covered a distance of 839 meters. (12/10)
"Newer, Nimbler, Faster:" Venus Probe
Will Search for Signs of Life in Clouds of Sulfuric Acid
(Source: Space Daily)
With multiple rovers landed and a mission set to return samples to
Earth, Mars has dominated the search for life in the solar system for
decades. But Venus has some fresh attention coming its way. A team led
by MIT researchers lays out the scientific plan and rationale for a
suite of scrappy, privately-funded missions set to hunt for signs of
life among the ultra-acidic atmosphere of the second planet from the
sun.
The first of the missions is set to launch in 2023, managed and funded
by California-based Rocket Lab. The company's Electron rocket will send
a 50-pound probe on board its Photon spacecraft for the five-month,
38-million-mile journey to Venus, all for a three-minute skim through
the Venusian clouds.
Using a laser instrument specially designed for the mission, the probe
will aim to detect signs that complex chemistry is occurring within the
droplets it encounters on its brief descent into the haze. Fluorescence
or impurities detected in the droplets could indicate something more
interesting than sulfuric acid might be wafting around up there, and
add ammunition to the idea that parts of Venus' atmosphere might be
habitable. (12/10)
Growing Trend Shows Demand for
Embry-Riddle Maintenance Students at Commercial Space Firms

Aviation Maintenance Science (AMS) students have been drawing attention
in recent years from a new suitor: commercial space companies. With at
least 16 students from Embry-Riddle Aeronautical University's AMS
program hired at SpaceX and Blue Origin within the past six years,
program leaders credit a steady evolution in the aviation and aerospace
sectors - namely, the commercial space boom: an increase in private
aerospace companies, rocket launches and space tourism.
"The space industry has grown rapidly following the government's
decision to open up contracts to private companies to provide
transportation of supplies and personnel to the International Space
Station," said AMS associate professor Marshall Tetterton. "Our
students are in demand to commercial space firms, in my opinion,
because the program here at Embry-Riddle covers and prepares them for a

Seeing a New Side of VP Kamala Harris
at National Space Council (Source: The Hill)
Vice President Harris recently conducted the first meeting of the
National Space Council (NSC) of the Joe Biden presidency, and she
handled it with competence and efficiency. It was a far departure from
the vice president’s recent cringeworthy video touting space
exploration for the next generation, which featured child actors.
Harris made the initial remarks, setting out the meeting’s agenda in
clear terms — and might boost her currently abysmal approval rating if
more people saw this side of her.
While the Biden administration has arguably gotten off to a rocky
start, the NSC meeting and the space priorities document demonstrate,
space policy is proving to be a bright spot for the current president
and vice president — albeit one that is not being well covered by the
media. Harris has gotten bad marks for gaffes since taking office.
However, if she can replicate what she did at the National Space
Council meeting in other venues, she may yet recover.
One problem not covered by the meeting is Congress’s underfunding of
both the Human Landing System and the commercial space stations that
should follow the International Space Station. If Harris, a former
senator, can sway Congress to appropriate more money for these and
other programs, she will have a success that will redound for her
political standing. (12/12)

Space and SPACs: A COVID Romance?
(Source: Space News)
For SPAC investors, the heavy focus on a quick ROI – and overall risk
aversion – may ultimately make SPACs and the space sector an imperfect
fit. The growth in popularity of Special Purpose Acquisition Companies
(SPACs) has impacted many industries, including the space sector. While
the relationship between the two dates back to the successful merger of
Iridium in 2008, the pace of SPAC activity in the space sector truly
accelerated in 2020 and 2021, marked by several high-profile mergers.
The majority have been successful, with redemption rates equivalent to
or lower than those in other SPAC mergers. However, there are several
examples of space companies with redemption rates of 50% or more – even
as high as 90% in the case of small satellite manufacturer Spire
Global, which went public in August 2021. Boston Consulting Group’s
analysis of current SPAC trends and the nature of traditional
investment in the space sector suggests that while some elements of
space are attractive to SPAC investors, the two may not be natural
long-term partners.
This potential lack of compatibility may stem from the typical desire
for quick returns with SPACs, versus the often long-term timelines to
profitability from space startups. Additionally, performance risks in
the space sector may be unappealing to SPAC investors. Numerous
companies in this sector have declared bankruptcy, while others have
suffered high-profile setbacks such as launch failures. (12/8)
