Evidence for a Massive
Biomass Burning Event at the Younger Dryas Boundary
(Source: Space Daily)
Some 13,000 years ago, a cataclysmic event occurred on Earth that was
likely responsible for the collapse of the Clovis people and the
extinction of megafauna such as mammoths and mastodons.
That juncture in the planet's geologic history - marked by a distinct
layer called the Younger Dryas Boundary - features many anomalies that
support the theory of a cometary cloud impacting Earth. The collision
triggered a massive biomass burning event, and the resulting soot, ash
and dust in the global atmosphere blocked out the sun, which prevented
photosynthesis - a phenomenon called impact winter. (2/8)
Researchers Validate
Satellite-Based Earthquake Early Warning System (Source:
Via Satellite)
A recent report in Seismological Research Letters suggests that
researchers can use satellites to provide early warnings of earthquakes
and tsunamis for Chile’s coastal communities. The module leverages
ground motion data measured by Global Navigation Satellite Systems
(GNSS) and could help determine the magnitude and epicenter of large
earthquakes.
The early warning module, called G-FAST, uses ground motion data
measured by Global Navigation Satellite Systems (GNSS) to estimate the
magnitude and epicenter for large earthquakes—those magnitude 8 and
greater. These great quakes often take place at subducting tectonic
plate boundaries, where one plate thrusts beneath another plate, as is
the case off the coast of Chile and the U.S. Pacific Northwest. (2/6)
If the Big One Hits Soon,
We Won't Have Any Warning (Source: Newsweek)
Whichever fault gives way first, scientists know the nightmare scenario
will happen eventually—the only question is when. If it happens
tomorrow, there won’t be any warning. “The way I know that an
earthquake is happening is I feel shaking,” said Robert-Michael de
Groot. And if people were going to know about shakes in advance, de
Groot would be one of them, since he works with the U.S. Geological
Survey's program to create earthquake warnings. USGS spent years
developing a system called ShakeAlert, designed in the long run to
offer an early warning of an earthquake, like the systems used in
Mexico and Japan.
These systems don’t predict earthquakes, a feat scientists currently
deem impossible. Instead, they exploit a quirk of how earthquakes work.
The shaking people feel on the surface is the result of waves on energy
flowing through the Earth—but those waves move much more slowly than
the ones into which we encode our communications. If there’s enough
distance between the source of the earthquake and the humans to be
warned, the signal can arrive moments before the shakes do.
But right now, ShakeAlert is underfunded. In fact, President Donald
Trump requested the project be tabled entirely in his administration’s
fiscal year 2018 budget plan, although Congress has reinstated funding.
Despite the struggles, it’s still being built, albeit more slowly than
USGS hoped, and they are testing applications with a few targeted
industries. (2/8)
Next for Falcon Heavy:
USAF Certification (Source: Space News)
The next big test for SpaceX's Falcon Heavy many not be a launch but
winning certification for national security missions. Gaining
certification for such payloads could require as few as two, and as
many as 14, successful launches, a spokesperson for the Air Force Space
and Missile Systems Command said. The wide range is based on the
details of any certification plan for the rocket agreed to between
SpaceX and the Air Force, where fewer launches could be replaced by
more in-depth technical evaluations. SpaceX CEO Elon Musk said after
Tuesday's launch that the company's backlog of commercial customer
should give the company enough of a track record to win Air Force
certification. (2/7)

Small satellite operators are encountering problems setting up ground

"We are working with about three to four other countries to figure out
whose law takes precedence, and it's a hard problem," said Tahara
Dawkins, director of NOAA's Commercial Remote Sensing Regulatory

Russians Are Mocking
Their Space Program After SpaceX Launch (Source: Vice)
The launch of Elon Musk’s Falcon Heavy rocket Tuesday captivated much
of the world. It also caused many Russians to suddenly see their own
country’s shining history of space exploration in a cold new light.
After all, their country put the first satellite, Sputnik, into orbit
in 1957, and the first human, Yuri Gagarin, into outer space four years
later. But Musk launched a cherry-red Tesla Roadster into orbit around
the sun, where SpaceX has claimed it would stay for millions of years.
Naturally, Russians reacted by launching memes about Russia’s current
space program and general state of affairs on social media. One Twitter
user posted a decrepit playground spaceship under the caption, “your
rocket.” And contrasted that with the Falcon Heavy as, “your mom’s
friend’s son’s rocket.” Meanwhile, on VK, Russia’s massively popular
homegrown social network, one user posted pictures of Russian
cosmonauts being blessed by a priest and asking, “When will we catch up
with SpaceX?” The priest mutters, “Quiet, quiet, kiss the cross.”
Some dove head-first into Russia's rising inequality and the excessive
wealth among the country's billionaire elite. One user noted the
millions of dollars and years of effort Musk has plowed into pioneering
space technology, and lamented the comparison with the kinds of things
Russia’s notorious 96 billionaires tend to spend their own money on.

Should Texas Give SpaceX
Another $5 Million for its Brownsville Spaceport? (Source:
Texas Standard)
SpaceX, is building a spaceport in Brownsville. It’s just taking a
little longer than expected. Initial projections by SpaceX founder Elon
Musk had rockets lifting off from the beachfront site by 2016. That
hasn’t happened, despite receiving over $15 million from the state of
Texas. Now, SpaceX is asking for more money to complete the project. In
January, the company applied for another $5 million from the state.
Alexander Salter explains what this means for Texas’ space industry.
Salter is an assistant professor of economics at Texas Tech University,
a fellow at the Texas Tech Free Market Institute and a member of TTU’s
brand-new Space Studies Hub. Salter takes a step back from the
spaceport construction project to frame the issue. “It’s
generally not a good idea for state governments to be in the interest
of picking economic winners and losers,” says Salter. “We
want government to be referee, rather than a player in the game.”
However, other states including Georgia, and even Puerto Rico are
courting SpaceX with a variety of incentives. “The risk,”
Salter says of Texas not extending more incentives, “is…losing SpaceX’s
business and the employment opportunities that it brings. The cost
overrun compared to projected benefits is not out of line for similar
projects.” He says that it’s common for projects of this
magnitude to take longer and cost more than initially projected. (2/7)

Internal Logs Show White
House Interviewed Science Adviser Candidates. But Who? (Source:

White House officials appear to have interviewed at least three people
last spring to lead the White House Office of Science and Technology
Policy (OSTP), a key post that remains vacant more than a year into the
administration of President Donald Trump. That information comes from
the appointments calendar of the de facto head of the office and its
only political appointee, Michael Kratsios.
The calendar was obtained by ScienceInsider under a Freedom of
Information Act (FOIA) request. The names of the candidates were
redacted for privacy considerations. However, the document provides
evidence that the Trump administration took steps to fill the position
of OSTP director within a few months of taking office. If true, that
would address widespread concerns by scientists that the president has
no interest in finding someone to coordinate the activities of some two
dozen federal agencies on matters relating to research, education, and
technological innovation. (2/6)
Musk Says SpaceX to Focus
on BFR Following Falcon Heavy Launch (Source: Tech Crunch)
Elon Musk said at a press event for the just-launched Falcon Heavy that
SpaceX will now begin focusing in earnest on “BFR,” the code name for
its next big space launch vehicle. BFR (aka “big f*cking rocket,” in
case you lack imagination) will be designed to be a vehicle capable of
using a single stage to make it all the way to orbit, with fully loaded
tanks.
Musk said that BFR might be ready for “short hopper flights with the
spaceship part” of the rocket by maybe next year. These will
essentially be flights of “increasing complexity,” with the intent
being to go out of Earth’s atmosphere and then “come back in hot to
test the heat shield,” because BFR’s primary purpose will require it to
survive planetary entry, on Earth, Mars and beyond.
Musk added that of BFR’s design challenges, “the ship part is by far
the hardest, because that’s going to come in from super-orbital
velocity” around planets including Mars, which is “way harder than
coming in from orbit.” (2/7)
