FSDC Urges Stepped-Up Action in
Tallahassee (Source: FSDC)
The Florida Space Development Council has urged elected officials to
provide more support to the space industry during the ongoing Florida
Legislative Session. FSDC President Gabriel Rothblatt asked Senate and
House leaders to take steps to diversify the state's involvement in
space research and technology development; continue financing programs
for space industry growth; fund conversion of the Shuttle Landing
Facility for new programs; establish a high school space education
academy; and fund a demonstration program for space tourism and
point-to-point spaceflight.
The five issues were prioritized by FSDC's membership through an online
survey. They were conveyed in letters to the Senate President, House
Speaker, and appropriation subcommittee chairs. The letters are posted here.

A New View of the Moon's Formation
(Source: U. of Maryland)
Within the first 150 million years after our solar system formed, a
giant body roughly the size of Mars (called "Theia") struck and merged
with Earth, blasting a huge cloud of rock and debris into space. This
cloud would eventually coalesce and form the moon.
For almost 30 years, planetary scientists have been quite happy with
this explanation--with one major exception. Although this scenario
makes sense when you look at the size of the moon and the physics of
its orbit around Earth, things start to break down a little when you
compare their isotopic compositions--the geological equivalent of a DNA
"fingerprint." Specifically, Earth and the moon are too much alike.
Now, a team of scientists has generated a new isotopic fingerprint of
the moon that could provide the missing piece of the puzzle. By zeroing
in on an isotope of Tungsten present in both the moon and Earth, the
team is the first to reconcile the accepted model of the moon's
formation with the unexpectedly similar isotopic fingerprints of both
bodies. The results suggest that the impact of Theia into early Earth
was so violent, the resulting debris cloud mixed thoroughly before
settling down and forming the moon. (4/8)
Plants Use Sixth Sense for Growth
Aboard the Space Station (Source: Space Daily)
Although it is arguable as to whether plants have all five human senses
- sight, scent, hearing, taste and touch - they do have a unique sense
of gravity, which is being tested in space. Researchers with the Japan
Aerospace Exploration Agency will conduct a second run of the Plant
Gravity Sensing study after new supplies are delivered by the sixth
SpaceX commercial resupply mission to the International Space Station.
The research team seeks to determine how plants sense their growth
direction without gravity. The study results may have implications for
higher crop yield in farming and for cultivating plants for
long-duration space missions.
The investigation examines the cellular process of formation in thale
cress, or Arabidopsis thaliana, a small flowering plant related to
cabbage. The genetic makeup of thale cress is simple and
well-understood by the plant biology community. This knowledge allows
scientists to easily recognize changes that occur as a result of
microgravity adaptation. (4/9)
Canada Gives Satellite Imagery to

Canada is providing Ukraine with Radarsat-2 imagery even as its own
military says it has restricted its use of the spacecraft. Canadian
government officials said earlier this year they agreed to a request
from Ukraine for radar images from the spacecraft, but declined to
discuss the cost of those images or how long they will be offered. The
Canadian military, meanwhile, says it's facing a "critical shortage" of
funds to cover Radarsat-2 imagery for its own needs because of budget

Seasonal, Year-Long Cycles Seen on the
Sun (Source: NASA)
Our sun is constantly changing. It goes through cycles of activity –
swinging between times of relative calm and times when frequent
explosions on its surface can fling light, particles and energy out
into space. This activity cycle peaks approximately every 11 years. New
research shows evidence of a shorter time cycle as well, with activity
waxing and waning over the course of about 330 days. (4/8)

What It Would Be Like to Live On a
Comet (Source: Space.com)
Photographs from comet missions have revealed that comet nuclei are
quite small, ranging from less than a mile to tens of miles across.
Some of them also have irregular shapes, sometimes resembling the end
of a dumbbell. "The reason they are so irregular is because their
gravity is so low," said Althea Moorhead.
On Earth and other spherical bodies, gravity is directed straight down.
But if you were on a dumbbell-shaped comet, gravity might pull you down
and to the side, depending on where you were standing, Moorhead said.
However, that gravitational tug wouldn't be overwhelmingly strong. The
gravity of Halley's Comet, for example, is about equal to the gravity
of Mount Everest if you were to remove the mountain from Earth and
deposit it in space — if you were to drop an object from chest level,
it would take about two minutes to hit the ground. (4/7)
Staying Healthy on the Red Planet
(Source: Slate)
When we think of astronauts, most of us imagine perfect physical
specimens—they should be brilliant, yes, but they should also be
stoutly built models of health. But some new discoveries suggest that
even the best of us may be ill-suited for the environments we’ll
explore in the future. To the contrary, making ourselves at home on
other worlds may mean learning to live with states of impairment.
Consider the case of Mars, a planet that has long been upheld as an
optimal candidate for colonization. The website of Mars One—the widely
criticized “not-for-profit foundation that will establish a permanent
human settlement on Mars”—lists six reasons why the red planet is
ideal. Among other things, the site notes that it has a limited
atmosphere, its days are similar to ours in length, and it is
relatively temperate.
Mars appeals to our terrestrial narcissism: We want to go there because
it’s a little like what we have here, such that we could call it home
without having to change quite so much about it. Mars also appeals
because of the evidence of water we’ve found there, especially in the
soil. The trouble is that water isn’t the only substance we’ve
discovered in the dirt of Mars. In 2009, scientists responsible for the
Phoenix lander reported that they had discovered a statistically
significant sample of perchlorate within the soil. Click here.

NASA's Chief Scientist: 'We'll Find
Alien Life by 2025.' Here's How (Source: Vox)
"I believe we are going to have strong indications of life beyond Earth
in the next decade and definitive evidence in the next 10 to 20 years,"
NASA's chief scientist, Ellen Stofan, said as part of a panel on
Tuesday. "We know where to look, we know how to look, and in most cases
we have the technology."
Stofan isn't alone. Scientists studying other worlds, both in our solar
system and orbiting distant stars, have also predicted that we're
likely to find out a lot about the existence of extraterrestrial life
in the coming decades. "With new telescopes coming online within the
next five or 10 years, we'll really have a chance to figure out whether
we're alone in the universe," Lisa Kaltenegger of Cornell University's

Organic Molecules Found Circling
Nearby Star (Source: Science)
Astronomers have detected chemical precursors of building blocks of
life in the large disk of dust and gas whirling around a young nearby
star. These complex organic molecules, two forms of cyanide and one
chemically related compound, likely formed after the protoplanetary

roughly similar proportions in comets circling our sun, which may have
brought them to Earth billions of years ago. (4/8)

Now Made in Brooklyn: Space Suits and
Spinoff Fashions (Source: New York)
At Final Frontier Design, in the Brooklyn Navy Yard, Ted Southern and
Nikolay Moiseev make space suits. An FFD space suit costs $65,000, and,
as you’d expect for anything so expensive, it’s really sleek. It's
lighter and easier to function in than the one most astronauts use now
— the FFD design features an easier-to-use helmet, lighter fabrics,
knees and elbows that allow for more flexibility, and 3-D-printed
buckles with rounded corners.
“It used to cost thousands of dollars to fit a machine to cut these
buckles,” said Southern. “Now we can 3-D print one for $30.” Southern,
an artist and designer who began his career working on technical
costumes for movies and theater, and Moiseev, who spent 20 years
working for the Russian space-suit company Zvezda, got their start
after winning a NASA challenge to design an astronaut glove — their
model outperformed NASA’s technology. Now they describe their company
as “a private design firm crafting aerospace safety garments for the
future of space travel.”
Brooklyn might seem strange place to be making space suits. But FFD is
working at the intersection of technology and fashion and has needs
that can't be fulfilled in an aerospace hub like Texas or Florida. “All
the space companies are in the countryside. I have been there, and
there are just no towns, nothing,” says Moiseev. “We need to be able to
hire professionals from all different trades, and everyone is in New
York." (4/8)

By the early 2030s, if predictions hold, NASA will be sending humans to
Mars. And Draper Laboratory, a non-profit research organization based
in Cambridge, will play an integral part in making sure the spacecraft
that sends the crew to the Red Planet is built properly. As part of a
