Star Hurtling Toward Our Solar System
Could Knock Millions of Asteroids Toward Earth (Source Business
Insider)
Researchers have known for a while that a star called Gliese 710 is
headed straight for our solar system, but they've now worked out
precisely when it should arrive. The star is currently hurtling through
space at about 32,000 mph, and is around 64 lightyears away. (One
lightyear is around 5,878,000,000,000 miles.)
Gliese 710 is about half the size of our sun, and it is set to reach
Earth in 1.35 million years. And when it arrives, the star could end up
a mere 77 light-days away from Earth — one light-day being the
equivalent of how far light travels in one day, which is about 26
billion kilometers, the researchers worked out. As far as we know,
Gliese 710 isn't set to collide directly with Earth, but it wil be
passing through the Oort Cloud, a shell of trillions of icy objects at
the furthest reaches of our solar system. (1/8)
Committing to Commercial Space Launch
(Source: Niskanen Center)
With the dawn of a new year, SpaceX is resolving to restart its
commercial space launches. After a pause of four months to investigate
the explosion of one of its rockets, the commercial launch company
announced plans to resume launches on January 8. Last September’s
accident sparked concerns about the safety of using commercial launch
companies. With a new administration coming into office this month, and
its signaled interest in space policy, it is important to highlight how
essential a robust commercial space launch industry is to American
interests.
The explosion of a SpaceX rocket in September led to questions from
lawmakers and a NASA advisory group about the safety of using the
company to launch national security satellites or astronauts. While
SpaceX has said it has identified the cause of the explosion, and has
worked to fix it, concerns about how to balance innovation and
reliability remain. These concerns are important, given what could be
at stake. Click here.

NASA Science Chief Seeks to Allay
Concerns About Transition (Source: Space News)
The head of NASA’s Science Mission Directorate, seeking to assure
astronomers concerned about the next administration, said that the
transition process has gone as he expected. Thomas Zurbuchen, NASA
associate administrator for science, said at a NASA town hall meeting
Jan. 5 during the 229th Meeting of the American Astronomical Society
here that he has had good interactions with the “landing team” assigned
to the agency by the transition team of President-elect Donald Trump.
“The meetings have been very thoughtful,” he said. “I think that, at
this stage of the process, it’s working the way it should.” (1/7)
High-Risk Satellite Conjunction Passes
Without Incident (Source: SpaceFlight 101)
The Joint Space Operations Center issued a notification that the close
approach of two non-maneuverable satellites did not result in a
collision: “The close approach predicted at 21:53:00 UTC on 7 Jan 2017
has passed without incident. The JSpOC has confirmed that both
satellites are being tracked as single objects, indicating that no
collision has occurred.” (1/7)
Is NASA Paving the Way for Asteroid
Mining? (Source: The Atlantic)
Earlier this week, NASA chose to fund an eponymous robotic mission to
Psyche, scheduled to launch in 2023. The mission marks the first time
spacecraft will visit a metallic asteroid, an extremely rare object in
the solar system. Similar NASA missions have only visited rocky and icy
worlds, like planets and other asteroids, like Vesta and Ceres.
Scientists believe Psyche could have grown to be the size of Mars, but
its rocky outer layers were smashed away by a series of collisions
billions of years ago. What remains, a world made of metallic nickel
and iron, is about the size of Massachusetts.
“By visiting Psyche, we can literally visit a planetary core the only
way that humankind ever can,” Lindy Elkins-Tanton, the Psyche mission's
lead investigator, told reporters Wednesday. “It’s 1,800 miles to the
Earth’s core, and the deepest humans have ever managed to drill is
seven-and-a-half miles.”
Psyche is the only known round metal body in the solar system. The
Psyche mission, led by researchers from Arizona State University, will
launch in 2023 and reach its namesake by 2030. Over 20 months, the
spacecraft will collect data about Psyche's composition and topography,
and, as is standard for robotic missions these days, return beautiful,
GIF-able images of the asteroid. They hope Psyche will help them better
understand planet formation, and learn more about Earth’s own iron
core. (1/6)

Some Pulsars Lose Their Steady Beat (Source:
Science News)
A pair of cosmic radio beacons known as pulsars keep switching off and
on, suggesting that there might be vast numbers of undiscovered pulsars
hiding in our galaxy. Pulsars are rapidly spinning neutron stars, the
ultradense cores left behind after massive stars explode. Neutron stars
are like lighthouses, sweeping a beam of radio waves around the sky.
Astronomers see them as steady pulses of radio energy.
But at least two in the Milky Way seem to spend most of their time
turned off, Victoria Kaspi, an astrophysicist at McGill University in
Montreal, reported January 4 at a meeting of the American Astronomical
Society. One, first detected at Arecibo Observatory in Puerto Rico in
November 2011, only pulses about 30 percent of the time. Another, also
discovered at Arecibo, laid down a steady beat just 0.8 percent of the
time when observed in 2013 and 2015. Then starting in August 2015, it
abruptly jumped to being on 16 percent of the time for several months.

China to Set Up Gravitational Wave
Telescopes in Tibet (Source: Xinhua)
China is working to set up the world's highest altitude gravitational
wave telescopes in Tibet Autonomous Region to detect the faintest
echoes resonating from the universe, which may reveal more about the
Big Bang.
Construction has started for the first telescope, code-named Ngari
No.1, 30 km south of Shiquanhe Town in Ngari Prefecture, said Yao
Yongqiang, chief researcher with the National Astronomical
Observatories of the Chinese Academy of Sciences. The telescope,
located 5,250 meters above sea level, will detect and gather precise
data on primordial gravitational waves in the Northern Hemisphere. It
is expected to be operational by 2021. (1/7)

‘Spaceport America’: 0 for 2016
(Source: KRWG)
If New Mexico’s spaceport offers “the world an invitation to space,” no
one’s RSVPing. In 2016, the facility launched … nothing. No satellites
placed in orbit. No tourists sent on one-of-a-kind journeys. Heck, even
UP Aerospace wasn’t able to launch a single sounding rocket last year.
But rest assured, taxpayers, economic-development “visionaries” are
doubling down. The Las Cruces Sun-News reports that construction “could
start late spring or early summer of 2017” on a 24-mile route from the
“Upham Exit of Interstate 25 north to Spaceport America.”
Instead of “investing” more in the spaceport, elected officials should
be looking to unload the white elephant. While a new version of the
bill hasn’t been drafted yet, let’s hope that legislation akin to
2015’s SB 267 reappears. Sponsored by Senator George Munoz (D-Gallup),
the bill would have required the development of “a marketing plan that
will advertise and promote the sale of Spaceport America to potential
national and international buyers.” (1/6)

Worth It? (Source: Paste)
Launching a man to the moon is among the greatest achievements in U.S.
history; yet, was it worthwhile? Is the technological innovation worth
the expense? Can the economic benefits outweigh the amount of pollution
produced by rockets? And aren’t there bigger problems to solve than
figuring out of one of Jupiter’s moons has ice? Here we examine whether
or not space travel is “worth it.” Click here.

Behind every John Glenn or Neil Armstrong or Buzz Aldrin there are tens
