Air Force Wants to Remind
You (and China) That its Secret Space Drone is Back
(Source: Quartz)
One of the weirdest open secrets in space has come back to earth: The
X-37B, an experimental US Air Force drone that looks and flies like a
miniature Space Shuttle, landed at Kennedy Space Center on May 7 with a
sonic boom that surprised local residents. The autonomous craft spent
718 days in space.
Unlike its previous three trips, when the Air Force provided few
details about its mission, this time military spokespeople can point to
two totally not nefarious at all science projects. While more
speculative analysts suspect electronic espionage directed at Chinese
spacecraft, the US Air Force says this is just a run-of-the-mill
experimental craft designed to demonstrate reusable space technology
can survive radiation, volatile temperatures and micro-asteroids.
This flight featured the test of an advanced US Air Force engine,
designed to propel spacecraft using thrusters powered by electrically
charged particles, as well as a NASA experiment to evaluate how dozens
of different materials withstand long-term exposure to space. (5/8)
Eight Incredible Feats
SpaceX Will Attempt in the Pursuit of Mars (Source:
Observer)
SpaceX has had a singular vision since its founding: to make humans a
multi-planetary species. That means financing and building the
infrastructure that will transport settlers to the first stop: Mars.
SpaceX was the first private company to dock a spacecraft at the
International Space Station, the first to successfully recover an
orbital-class rocket after a mission. And recently, they shook the
entire aerospace industry by reflying one of those rockets—an
accomplishment that has far-reaching implications for the future of
spaceflight. Click here.

Planetary Protection:
Contamination Debate Still Simmers (Source: Space.com)
On Sept. 15, 2017, NASA's Cassini spacecraft will take a suicide plunge
into Saturn to avoid contaminating the ringed planet's potentially
habitable moons, Titan and Enceladus. Cassini's fate is tied to the
issue of planetary protection, which refers to the measures scientists
and engineers take to minimize that chances that life-forms from Earth
make it to other worlds. And with NASA's Mars 2020 rover planning to
cache samples to one day return to Earth's labs, planetary protection
also means making sure that our own world is safe from contamination by
possible alien life. (5/9)

First Latina In Space To
Be Inducted Into US Astronaut Hall of Fame (Source: KPBS)
When Ellen Ochoa was growing up in La Mesa in the 60’s, a career in
space exploration did not cross her mind. “At that time there weren’t
women astronauts, they weren’t allowed to apply. And actually you saw
very few women at all working at NASA. So, it’s something that at that
time I never thought about growing up and doing,” she said. It was not
until she was in graduate school that her interest in joining NASA’s
astronaut program grew.
In 1993, Ochoa became the first Latina to travel to space. She was part
of a 90-day space mission to study the Earth’s atmosphere aboard the
space shuttle Discovery. As an astronaut, Ochoa has flown on four space
missions, logging almost 1,000 hours in orbit. This month, Ochoa will
be inducted into the U.S. Astronaut Hall of Fame. (5/8)

Why Comets Have Oxygen
Atmospheres (Source: Cosmos)
Why would a comet have oxygen in its atmosphere? That’s the question
that has been troubling scientists since the European Space Agency’s
Rosetta spacecraft visited the comet 67P/Churyumov-Gerasimenko in 2015,
and made the surprising discovery that the comet’s wispy-thin
atmosphere did indeed contain molecular oxygen.
Molecular oxygen, otherwise known as the common gas O2 where on Earth,
where it is a byproduct of life, is rare in space: oxygen atoms are
more likely to bond with hydrogen (to form water, H2O) or carbon (to
form carbon dioxide, CO2). The presence of O2 on the comet has been
something of a mystery, but an answer has come from a surprising
source. Konstantinos P. Giapis is a professor of chemical engineering
at Caltech, whose work on collisions of high-speed ions with
semiconductor surfaces has in the past been applied mainly in computer
chip manufacture.
“What I’ve been studying for years is happening right here on this
comet,” Giapis says. If water molecules flew off the comet under
heating by the sun, the molecules could be ionized (split into their
component atoms) by the solar radiation, which would also push them
back toward the comet’s surface. At the surface, the loose oxygen atoms
could meet and bond with oxygen atoms contained in materials such as
rust and sand, forming O2. (5/9)
Space: The Final(?)
Frontier of Taxation (Source: Conservative Review)
In its continuing quest to become a caricature of itself, California is
announcing plans for a new tax policy targeting space travel.
Commercial spaceflight companies based in the state will be expected to
pay a fee to the government for every mile traveled.
If this sounds silly, it’s because it is. Commercial space travel is
likely to become a major industry over the next several decades, and I
guess California wants to get in early to claim a piece of the pie, but
it’s a completely wrong-headed move on a number of levels.
The tax will not only apply to space tourism, but to cargo as well. The
idea of commerce in space may seem like science fiction, but it is not
at all unrealistic to assume that transporting goods to space could
become a major industry, especially given that the international space
station already requires regular deliveries. California is trying to
spin the tax as “actively engaging” with industry. I guess that’s one
way of putting it, if your definition of “actively engaging” includes
“chasing away.” (5/8)

The Scientific Truth
About Planet Nine, So Far (Source: Forbes)
Last year, two astronomers were looking at the most distant objects
orbiting our Sun ever discovered, when they noticed something funny.
These ultra-distant Kuiper belt objects, instead of having their orbits
oriented at random, were both swept off in one particular direction and
tilted in the same direction. If you only had one or two objects doing
this, you might chalk it up to random chance, but we had six; the odds
that this would be random was around 0.0001%.
Instead, astronomers Konstantin Batygin and Mike Brown proposed a
radical new theory: that there was an ultra-distant ninth planet — more
massive than Earth but smaller than Uranus/Neptune — knocking these
objects into their new orbits. 16 months later, here's the scientific
truth, so far. Click here.

What To Do with NASA's
Defective SLS Fuel Tanks? (Source: NasaSpaceFlight.com)
NASA is pondering what to do with fuel tanks built for the Space Launch
System that may have defective welds. Engineers discovered an issue
with the friction stir welding system used to make the SLS propellant
tanks at the Michoud Assembly Facility in New Orleans and corrected it
while making liquid oxygen tanks. The problem, though, was found after
the system was used to weld two liquid hydrogen tanks, including one
planned for the first SLS launch. Given concerns that the welds may be
below their rated strength, NASA is evaluating options to either repair
the welds or produce a new tank. (5/9)

Man-made space radiation has been produced in research led by the

laser-plasma-based accelerators to mimic the radiation, which presents
a risk to astronauts and space technology owing to the lack of
protection from it in space. The study, funded by the European Space
Agency (ESA), shows for the first time that this type of device can be
