China’s Quest to Become a
Space Science Superpower (Source: Nature)
At mission control, a gigantic screen plays a looping video showcasing
the country's major space milestones. Engineers focus intently on their
computer screens while a state television crew orbits the room with
cameras, collecting footage for a documentary about China's meteoric
rise as a space power. The walls are festooned with motivational
slogans. “Diligent and meticulous,” says one. “No single failure in
10,000 trials,” encourages another.
China is rushing to establish itself as a leader in the field. In 2013,
a 1.2-tonne spacecraft called Chang'e-3 landed on the Moon, delivering
a rover that used ground-penetrating radar to measure the lunar
subsurface with unprecedented resolution. China's latest space lab,
which launched in September 2016, carries more than a dozen scientific
payloads. And four additional missions dedicated to astrophysics and
other fields have been sent into orbit in the past two years. (7/26)

Breast Cancer Ribbon on ISS (Source: CollectSpace)
A race car driver's personal mission will tie together breast cancer
awareness and the International Space Station using a zero-g 3D printer
and the auction of a very special pink ribbon.
Pippa Mann, whose bright pink and white race car bore the logo of Made
In Space for the Indianapolis 500 in May, is extending her partnership
with the in-space manufacturing company to beyond the track and all the
way to orbit. This October, during Breast Cancer Awareness month, Made
In Space will use its commercial 3D printer aboard the station to
create a pink ribbon, which will be returned to Earth and auctioned to
benefit the Susan G. Komen foundation. (7/26)
Senate Moves to Bump Up
NASA Budget (Source: Space News)
A Senate subcommittee approved an appropriations bill that provides
more than $19.5 billion for NASA in 2018. The commerce, justice and
science appropriations subcommittee approved the bill during a brief
markup session Tuesday afternoon. The bill increases NASA's budget by
more than $400 million from the White House request, but offers $340
million less than a House bill. The Senate bill includes increases for
the Space Launch System and Orion, and restores funding for NASA's
education office. The same bill also provides full funding for NOAA's
weather satellite programs. The full Senate Appropriations Committee is
scheduled to mark up the bill Thursday. (7/25)
CFIUS Blocks Chinese
Satellite Deal with US Company (Source: Space News)
A proposed joint venture between satellite connectivity provider Global
Eagle Entertainment and a Chinese company has been blocked by U.S.
regulators. Global Eagle said in a regulatory filing Tuesday that the
companies terminated a pending investment agreement because they could
not get approval from the Committee on Foreign Investment in the United
States (CFIUS) for the deal. Beijing Shareco Technologies had planned
to invest $416 million into Global Eagle for a one-third stake in the
company as part of the agreement. CFIUS, which reviews proposed foreign
investments in U.S. companies, concluded the deal had unspecified
"national security concerns," according to Global Eagle CEO Jeff Leddy.

Cassini Trying to Measure
Saturn's Rotation (Source: Space.com)
Time is running out for Cassini to complete one of its science
objectives: measure the length of a day on Saturn. Scientists have
planned to use the final phases of Cassini's mission at Saturn to
precisely calculate the planet's rotational period by measuring the
wobble of its magnetic field. However, the magnetic field is almost
exactly aligned with its rotational axis, making those measurements
more challenging than expected. "We have not been able to resolve the
length of day at Saturn so far, but we're still working on it," said
one scientist. (7/26)
The Sound of Space
(Source: Washington Post)
If you could hear sounds in space, it might sound like a "chorus of
alien birds." A physicist working on NASA's Van Allen Probes mission
has converted the radio waves detected by the spacecraft in the Earth's
magnetosphere into sound waves of the same frequency. The sounds are
entertaining, but also help scientists better understand the creation
and propagation of those radio waves. (7/26)

NASA to Share Tech From
Supersonic Project (Source: Bloomberg)
Lockheed helped create NASA’s design, using fluid dynamics modeling
made possible in the past decade or so by increasingly powerful
computers. Together, Lockheed and NASA tested and mapped how subtle
differences in aircraft shapes affect the supersonic shock waves they
create. The design they’ve settled on keeps sound waves from merging
into the sharp N pattern of a sonic boom, according to Peter Iosifidis,
Lockheed’s design program manager on June’s small-scale model. Instead,
the waves are kept dispersed across a wide range of points behind the
plane, leaving the resulting supersonics a mere hum.
NASA plans to share the technology resulting from the tests with U.S.
plane makers, meaning a head start for the likes of Lockheed Martin,
General Dynamics, Boeing, and startups such as Boom Technology and
billionaire Robert Bass’s Aerion. Click here.

NASA Seeking BIG Ideas for Solar Power
on Mars (Source: SpaceRef)
Missions to the surface of distant planetary bodies require power —
lots of power. Through the 2018 Breakthrough, Innovative, and
Game-changing (BIG) Idea Challenge, NASA is enlisting university
students in its quest for efficient, reliable and cost-effective solar
power systems that can operate on Mars both day and night. The teams
will have until November to submit their proposals. Interested teams of
three to five undergraduate and/or graduate students are asked to
submit robust proposals and a two-minute video describing their
concepts by Nov. 30.
NASA’s Game Changing Development Program (GCD), managed by the agency’s
Space Technology Mission Directorate, and the National Institute of
Aerospace (NIA) are seeking novel concepts that emphasize innovative
mechanical design, low mass and high efficiency, with operational
approaches that assure sustained power generation on the Mars surface
for many years. (7/24)
Noise in Gravitational-Wave Data Casts
Doubt on Historic Finding (Source: WIRED)
A team of independent physicists has sifted through the data from the
historic LIGO gravitational wave detection, only to find what they
describe as strange correlations that shouldn’t be there. The team
claims that the troublesome signal could be significant enough to call
the entire discovery into question. The potential effects of the
unexplained correlations “could range from a minor modification of the
extracted wave form to a total rejection of LIGO’s claimed
[gravitational wave] discovery."
LIGO representatives say there may well be some unexplained
correlations, but that they should not affect the team’s conclusions.
The technical issues at stake here have to do with the extreme
difficulty of the measurements that LIGO attempts to make.
Gravitational waves are exceedingly faint, so to catch them LIGO was
built with the ability to measure a change in distance just
one-ten-thousandth the width of a proton. Lots of little bumps and
vibrations can mimic a gravitational-wave signal, so LIGO uses two
observatories, 3,000 kilometers apart, which operate synchronously,
each double-checking the other’s observations. (7/24)
Inner Strength for Outer Space

The glamorous parts of spaceflight — ascending skyward on a pillar of
fire, floating gracefully against a backdrop of stars — are in some
ways the easiest on the astronauts’ minds and bodies, as long as
nothing goes wrong. As NASA eyes the long-term future of human space
exploration and missions to Mars, medical and psychological challenges
are among those that loom largest. Click here.
