South Korea’s New Space Agency
Outlines Plans (Source: Space News)
South Korea’s new space agency, less than two months old, is laying out
ambitious goals in spaceflight as part of its efforts to serve as a
“control tower” for the county’s growing space presence. The Committee
on Space Research (COSPAR) 45th Scientific Assembly held here served as
one of the first opportunities for the Korea Aerospace Administration,
or KASA, to tell an international audience about its plans to
coordinate and expand space activities in the country.
KASA started operations on May 27. The agency, Youngbin Yoon said,
“serves as the control tower for national space affairs and
international cooperation,” with the goal of creating an aerospace
economy in South Korea. That work will be focused on space
transportation, satellite, space exploration and aviation. KASA has
long-term goals, he added, of sending a robotic lander to the moon in
2032 and another to Mars in 2045. (7/20)
Astronomers Discover What May Be 21
Neutron Stars Orbiting Sun-Like Stars (Source: Phys.org)
Most stars in our universe come in pairs. While our own sun is a loner,
many stars like our sun orbit similar stars, while a host of other
exotic pairings between stars and cosmic orbs pepper the universe.
Black holes, for example, are often found orbiting each other. One
pairing that has proven to be quite rare is that between a sun-like
star and a type of dead star called a neutron star.
Now, astronomers led by Caltech's Kareem El-Badry have uncovered what
appear to be 21 neutron stars in orbit around stars like our sun.
Neutron stars are dense burned-out cores of massive stars that
exploded. (7/16)
'Dark Comets' May Be a Much Bigger
Threat to Earth Than We Thought (Source: LiveScience)
Mysterious, nearly invisible objects known as "dark comets" may pose a
bigger threat to Earth than scientists thought, new research suggests.
These small, rapidly spinning objects wander near Earth, likely after
migrating from more distant reaches of the solar system. They might be
a source of water and other volatile elements — and also a potent
source of danger.
Dark comets are small — only tens of kilometers across. They show no
visible outgassing or evaporation of volatile elements like water. But
they don't move in perfect orbits, either. Instead, they show evidence
for "nongravitational" acceleration, implying that there are some other
forces capable of gently nudging their orbits. (7/20)
Patented 'Exodus Effect'
Propellantless Propulsion Drive that Defies Physics is Ready to Go to
Space (Source: The Debrief)
A patented experimental propellantless propulsion drive is finally
ready to go to space, according to its inventor, a veteran NASA
scientist with decades of expertise in electrostatics. Dr. Charles
Buhler, the technology’s creator, says the propulsion system may
represent a working version of Quantized Inertia.
The controversial technology, which The Debrief covered in April, is
privately owned by Exodus Propulsion Technologies and is not affiliated
with NASA. After almost a decade of research, design, and testing,
Buhler says he and his team are confident they have verified the force,
one his team calls the Exodus Effect. The final step required to
officially demonstrate the validity of their discovery is to send the
propulsion drive unit into space. (7/19)
China Plans to Deflect Near-Earth
Asteroid in 2030 (Source: New Atlas)
China is looking to get into the planetary defense business. A new
paper by the China National Space Administration (CNSA) confirms that
in 2030, the country plans to conduct a test mission to deflect a small
asteroid from its current course. If you're going to have a space race,
making the goal to develop a way of protecting the Earth from rogue
asteroids is one of the more benign ones. Assuming, of course, that no
one gets the idea of using the technology to deflect asteroids towards
the Earth. That gets into Bond villain territory. (7/17)
Airbus Looking at Opportunities to
Create Scale in Space, Satellites (Source: Reuters)
Airbus is looking at opportunities to create scale in defense, space
and particularly satellites markets, CEO Guillaume Faury said on
Sunday. Airbus and France's Thales are exploring a tie-up of some space
activities as new competition disrupts the sector, two industry sources
said last week. The sources said preliminary talks were focusing on the
companies' overlapping satellite activities.
Airbus and Thales Alenia Space, in which Italy's Leonardo holds a 33% stake, are Europe's largest makers of
satellites for telecommunications, navigation and surveillance. Demand
for their geostationary satellites is increasingly under pressure as
traditional manufacturers face competition from massive constellations
of expendable satellites in low Earth orbit. (7/21)
Sci-Fi Horror Bug Discovered on
International Space Station (Source: Fox8)
Aboard the International Space Station, NASA discovered 13 strains of a
superbug, a multidrug-resistant bacterium. Its name? Enterobacter
bugandensis. Having mutated in the extraordinary (and extraordinarily
isolated) environment of outer space, the microscopic oddity is
genetically distinct enough from its terrestrial counterparts to
develop resistance to drugs.
It spells out prospective health risks—particularly to astronauts’
respiratory systems. Astronauts already suffer from weakened immune
systems while on the space station. The discovered mega bug could
especially assail astronauts in this state, potentially sickening them
in a less than ideal environment. Obviously, the limited access to
medical facilities in space adds to the difficulty. (7/21)
ScienceAlert: This Plant Is So Extreme
Scientists Think It Could Thrive on Mars (Source: ScienceAlert)
Mosses are among Earth's great terraformers, turning barren rock into
fertile soils, and now a team of scientists is proposing these
non-vascular plants could do the same on Mars. Whether we should
introduce life from Earth onto our red neighbor is another question –
we don't have a great track record with this on our own planet.
But if we decide it's worth messing with soil on Mars to create a
second home for us Earthlings, ecologist Xiaoshuang Li and colleagues
at the Chinese Academy of Sciences have a candidate that they think
should do just the trick. Syntrichia caninervis is committed to
upholding a severely frugal way of life. It thrives in the deserts of
China and the US, along with the icy mountains of the Pamir, Tibet, the
Middle East, Antarctica, and circumpolar regions. (7/21)

Even big spacecraft on a mission to map the stars have to deal with the
hazards of space. According to the European Space Agency, the Milky Way
"billion-star surveyor" satellite called Gaia was struck by a
high-speed micrometeoroid that was "smaller than a grain of sand" in
April before being hit by the strongest solar storm in 20 years – the
same storm that led to brilliant auroras on Earth in May. This affected
the craft's ability to carry out the precise measurements for which it
is famous. (7/20)
Senate Spending Bill Includes NASA
Funding Increase (Source: Space News)
A spending bill a Senate committee will debate this week includes a
funding increase for NASA. The Senate Appropriations Committee is
scheduled to mark up its commerce, justice and science (CJS) fiscal
year 2025 spending bill Thursday, along with three other bills.
While the text of the bill has not been released yet, the leaders of
the CJS subcommittee said Monday that the bill will include an
unspecified increase for NASA, and will specifically protect the
Artemis lunar exploration effort. They didn't discuss how the bill will
differ from a House bill that appropriations advanced earlier in the
month to provide a smaller increase than requested by NASA for 2025.

Thales Alenia Team Wins French
Satellite Inspection Contract (Source: Space News)
A team lead by Thales Alenia Space won a French government contract to
operate a satellite inspection mission. Supported by undisclosed
funding from the French space agency CNES and state-owned investment
bank Bpifrance, the mission would use a pair of spacecraft due to
launch before the end of 2028 as part of the European Robotic Orbital
Support Services (EROSS) program.
The French effort, called Démonstration d'Inspection et Amarrage
Novatrice Embarquée (DIANE), will use the EROSS spacecraft to inspect a
spinning satellite and capture it. The timeline for DIANE depends on
the availability of the EROSS assets, but in principle the mission
could start as soon as the initial EROSS demonstration is over. (7/22)
ESA Apophis Mission Proceeds Ahead of
Funding Decision (Source; Space News)
ESA is allowing a proposed mission to the asteroid Apophis to move
ahead before a funding decision next year. ESA announced last week that
it gave the Ramses mission permission to begin preparatory work before
a funding decision at the 2025 ministerial meeting. Ramses, or Rapid
Apophis Mission for Space Safety, is based on the Hera asteroid mission
scheduled to launch in October.
It would launch in 2028 and arrive at Apophis about two months before
the asteroid makes a very close flyby of Earth. It would complement
NASA's OSIRIS-APEX mission, which will arrive at Apophis after the
flyby. Project officials said they needed the approval to start work
now before the ministerial to keep Ramses on schedule. (7/22)

UK Parastronaut Can Fly to Space
(Source: The Telegraph)
A British "parastronaut" can safely fly to space, an ESA study has
concluded. The feasibility study by ESA found no "technical
showstoppers" that would keep John McFall, a British man with a
prosthetic leg, from going to space. ESA selected McFall as an
astronaut candidate in 2022 to see if people with physical limitations
could participate in missions. McFall would still wear his prosthesis
in space, with studies ongoing about any design changes needed for it.
The study does not guarantee that McFall will go on a future mission to
the International Space Station but shows that, if selected, he could
be a full member of the crew. (7/22)

ISS Could 'Drift Down' for a Year
Before SpaceX Vehicle Destroys it in Earth's Atmosphere (Source:
Space.com)
SpaceX's newly commissioned reentry vehicle will only push the ISS into
Earth's atmosphere some 12 to 18 months after the complex "drifts down"
from its normal orbit. "We'll leave the crew on board as long as
possible, so they're available to help maintain station and keep it
healthy," NASA's Dana Weigel, ISS program manager, told reporters.
"Our plan is for [the astronauts] to leave about six months before the
final reentry, as ISS reaches about 220 kilometers [136 miles]," Weigel
said, explaining that's as low as human vehicles are typically rated to
fly. For comparison, the typical ISS orbit is 250 miles (400 km) above
Earth. (7/17)
