NASA Wants to Send a
Probe to the Hellish Surface of Venus (Source: WIRED)
With all the talk about sending humans to the moon and eventually Mars,
it can be easy to forget there are other planets worth exploring. But a
team of researchers at NASA has set its sights on Venus, Earth’s
closest neighbor and one of the least understood planets in the solar
system. Since the first (crash) landing on Venus in 1966, by a Soviet
probe, spacecraft have only survived a total of a few hours on the
planet’s surface.
But NASA’s new probe is being designed last up to 60 days on the
punishing Venusian surface. Known as the Long-Lived In-situ Solar
System Explorer, or LLISSE, each of the probe’s components is specially
engineered to withstand the high temperature, high pressure, and
reactive atmosphere that define that infernal planet. Unlike the
car-sized rovers NASA drops on Mars, LLISSE is small because it will
have to hitch a ride with other spacecraft headed to the neighborhood.
It’s a cube less than 10 inches to a side, and it's packed with
instruments to test everything from the Venusian atmosphere to its
geology. (10/23)

Force Rollout Plan (Source: Space News)
The White House has directed the Pentagon to develop a public
communications plan for the Space Force. While the new military branch
is still pending congressional approval, the White House wants to be
ready for a public rollout event soon after it is approved — and in
less than the 90 days that the Defense Department had been planning to
formally stand up the Space Force. Administration officials expressed
concern that the Defense Department does not yet have Space Force
visuals, such as a flag and seal, that the president would expect to
show at a rollout event, and White House also would like to move
quickly to nominate a chief of staff of the Space Force. (10/23)

Mars Soil Is Very Weird,
the Mole's Struggles Show (Source: Space.com)
The mole's Mars struggles have not been in vain. The burrowing heat
probe aboard NASA's InSight Mars lander was designed to go 10 to 16
feet (3 to 5 meters) underground, using a self-hammering tool dubbed
"the mole." But the mole got stuck just a foot (0.3 m) or so down
shortly after its February 2019 deployment and could not be budged for
months. "We scratched our heads for quite a while trying to figure out
what we could do," InSight project manager Tom Hoffman said.
The InSight team homed in on two possible explanations for the mole's
lack of progress: Either there was a big rock blocking its way, or the
little digger had lost friction with the Red Planet's soil. Without a
good grip on the dirt, the mole can't move much. Last week, we got some
good news: The InSight team had gotten the mole to move a few
centimeters using a "pinning" technique, pressing the lander's soil
scoop against the mole to create friction. That result showed that
hypothesis number two was probably on the money and offered hope that
the mole could eventually get down to its prescribed depth.
But even if that doesn't end up happening, the mole will still have
taught the team some interesting things about Mars. For example, unlike
typical holes dug here on Earth, the one excavated by InSight's mole
has no lip of dirt around its rim, Hoffman said. "Where did the soil
go?" he said. "Basically, it got pounded back into the ground, so it
seems like it’s very cohesive, even though it’s very dusty." And this
is a weird combination of characteristics, strongly suggesting that
Mars dirt is alien in more ways than one. (10/23)

New RUAG Rocket Fairing
Design Offers Smoother Quieter Ride (Source: Space Daily)
Satellites are built to live in the harsh environment of space but
engineers must also factor in the rigours of the journey there. ESA has
helped RUAG Space Switzerland to develop new rocket fairings that offer
a smoother quieter ride to space. RUAG manufactures fairings for
Europe's Ariane and Vega launchers and has recently shown how a
micro-perforation of the facesheet of the panels of the fairing can
reduce noise and vibrations, and how a new hinge and actuation system
could reduce the shock of separating the fairing from the launch
vehicle when it reaches space.
Pyrotechnic systems for fairing separation require thorough testing
before being qualified for flight, which is intense, expensive and
requires vacuum conditions. A major benefit of RUAG's replacement
low-shock separation and jettison system is that no expensive vacuum
chamber is needed for tests because separation relies on a slightly
slower non-pyrotechnic process making the friction with air in ground
testing much less significant. RUAG can achieve the same results using
a set of pre-loaded hinges and pneumatic actuators combined with a
passive jettison system that pushes the parts away once the separation
systems are actuated. (10/23)

the rover show that material is likely "impact glass" created when
minerals are melted during impacts. Astronauts found similar impact
glass material during the Apollo 17 mission. (10/23)
Spacesuit Gloves
Contaminated During All-Woman Spacewalk (Source: Space.com)
The spacesuit gloves of a NASA astronaut were contaminated during the
historic all-woman spacewalk on Friday (Oct. 18), but it's probably

embarked on a spacewalk to replace one of the International Space
Station's battery charge-discharge units (BCDU), there was a
contaminant on one of Koch's gloves when she re-entered the station.
But it's most likely that this "contaminant" is just grease from the
station's Canadarm2 robotic arm, Koch said during a post-spacewalk

New SMC Focus: Space
Control, ‘Domain Awareness’ (Source: Breaking Defense)
The Air Force has created a new Special Programs Directorate aimed at
“delivering special space capabilities to dominate in war, in, from and
through space,” says its head, Col. Stephen Purdy. Purdy said the new
directorate — part of Space and Missile Systems Center (SMC) — is a
redesign of the former Space Superiority Systems Directorate, “focused
on end to end space control,” instead of simply space situational
awareness (SSA).
“We are the integrators of space control,” Purdy said in his slide
presentation. He noted that the “number one mission of the directorate
is to work across SMC, with the National Reconnaissance Office (NRO),
and other mission partners to deliver space warfighting capabilities.”
The shift seems to signal a stronger focus on development of systems
for detection, tracking and targeting of enemy spacecraft. Space
control in Joint Doctrine refers to both defensive operations (which up
to now has included SSA) and offensive counterspace operations (which
Air Force officials are loathe to discuss in public.) (10/21)

Robots to the Moon In 2021 (Source: Tom's Guide)
A private British space company is planning to send a 2-pound spider
robot to the moon, the first crawling rover to walk in our satellite.
And if it’s successful, more will follow so they can help us establish
permanent colonies and scare the hell out of lunar kids. UK-based
Spacebit will launch on board the Peregrine, a lander made by a U.S.
company called Astrobotic. The Peregrine will get to Moon thanks to a
United Launch Alliance Vulcan rocket that will launch from Cape
Canaveral some time in 2021.
Once on the surface of the Moon, the creepy crawler will start its
10-day-long mission to recognize the terrain around the rover using its
onboard full HD video camera. The spider will also have laser eyes to
take depth data: a 3D LIDAR system will map the terrain around it in
detail to send it back to Earth. (10/22)
The Biggest Barrier to
Future Space Exploration is in Our Heads (Source: Fast
Company)
In 1945 British science fiction writer Arthur C. Clarke—now best known
for 2001: A Space Odyssey—correctly predicted the invention of
satellites, the first of which launched into space in 1958. Then in
1963, Clarke predicted that a man would land on the moon and safely
return to Earth sometime around the year 1970—which Neil Armstrong and
Buzz Aldrin did in the summer of 1969. In 1973, Clarke predicted a
future where humans would be able to monitor outer-space threats such
as asteroids and other near-earth objects—NASA established its
Near-Earth Object Observations Program in 1998.
Much of what Clarke suggested about our future in outer space, however,
has slipped further and further behind schedule in recent years. For
example, he predicted commercial space flights by the year 2011 and a
manned mission to Mars by 2021. He also spoke of a manned mission to
Jupiter by 2099, which experts say looks pretty unlikely at this point.
Clarke was hardly alone in his optimism about what we could accomplish
in outer space, and when we might accomplish it. Many others—including
experts whose field was science rather than science fiction—have made
predictions that we’ve failed, so far, to turn into reality. Why has
the trajectory of our reach into space gone so far off course? Click here.

Hypersonic Planes a Step
Closer After Breakthrough That Prevents Engine Melting at 4,000mph
(Source: The Telegraph)
Hypersonic planes that can take passengers from London to New York in
under an hour are a step closer to reality thanks to British
technology. Engineers at Oxfordshire-based Reaction Engines have
successfully tested a pre-cooling system that allows engines to
withstand Mach 5, or speeds of nearly 4,000mph.
Mach 5 is more than twice as fast as the cruising speed of Concorde and
more than 50pc faster than the SR-71 Blackbird aircraft, the world’s
fastest jet-engine powered aircraft. However, travelling at such an
extreme speeds has been hard to achieve up until now because the
extreme conditions cause the engine to melt. Air entering at Mach 5 can
reach in excess of 1,000 degrees. (10/22)

Impeachment is
Threatening to Derail Trump’s Mission to the Moon (Source:

On Dec. 11, 1998, the Judiciary Committee in the US House of
Representatives approved three articles of impeachment for president
Bill Clinton. The week before, on Dec. 4, NASA launched its first
module to the orbiting platform that would eventually become the
International Space Station. Despite the chaos then engulfing the
capital, the space agency managed to kick-off the most successful space
project of the last two decades, the orbiting lab that has been the
focus of the world’s human spaceflight efforts for two decades.
President Donald Trump’s administration is now attempting to get its
own ambitious program off the ground, with a goal of landing
astronauts, including the first woman, on the moon by 2024, four years
sooner than planned. US lawmakers have not committed to funding this
project on the president’s schedule, and NASA now says it
won’t be able to even estimate the full cost of it until 2020. With the
impeachment inquiry announced by Speaker of the House Nancy Pelosi on
Sep. 24 deepening, the White House’s political capital is likely to be
more focused on defending the president than winning space bucks to
meet the new deadline.
What made things different in the 1990s? Clinton, never known as the
most disciplined president, managed to keep up the public appearance of
business as usual during his impeachment proceedings. He
“compartmentalized” his staff to focus on work and delivered boring
speeches about policy, two things Trump is unlikely to do. (10/22)

The Dinosaur-Killing
Asteroid Acidified the Ocean in a Flash (Source: Business
Insider)
About 66 million years ago, an asteroid more than 6 miles wide struck
modern-day Mexico. The impact sparked wildfires that stretched for
hundreds of miles, triggered a mile-high tsunami, and released billions
of tons of sulfur into the atmosphere. Within a minute of
hitting the Earth, the Chicxulub asteroid had bored a hole nearly 100
miles wide into the sea floor, creating a bubbling pit of molten rock
and super-hot gas. The contents of that fiery cauldron skyrocketed,
creating a mountain-high plume that poured acid rain into the oceans.
While scientists knew catastrophic events on land following the
asteroid's impact triggered the mass extinction of 75% of life on Earth
(including the dinosaurs), the mechanism by which ocean species
perished was less certain. Now, a study in the journal Proceedings of
the National Academy of Sciences found that the barrage of acid rain
following impact was probably the killer. After the asteroid crash, the
study authors wrote, the oceans underwent rapid and intense
acidification. That then disrupted marine food webs and sparked a mass
extinction. (10/21)

encourage the responsible commercial use of these resources.”
Pence hinted that the United States will be developing new policies
relating to the use of space resources. “We will use all available
legal and diplomatic means to create a stable and orderly space
environment that drives opportunity, creates prosperity and ensures our
security on Earth into the vast expanse of space,” he said. (10/22)
