Strange Objects that
"Look Like Gas and Behave Like Stars" Discovered Orbiting Milky Way's
Supermassive Black Hole (Source: CBS)
The supermassive black hole at the center of our galaxy, the Milky Way,
is always up to something unusual. Now, astronomers have spotted
strange new objects close by — and they aren't quite sure what they
are. Using 13 years worth of data from the W.M. Keck Observatory in
Hawaii, astronomers were able to identify a new class of objects
extremely close to the black hole, Sagittarius A*. The six objects,
named G1 through G6, appear to be interacting with the black hole.
"These objects look like gas and behave like stars," co-author Andrea
Ghez said in a statement. (1/15)
Bezos and the Idea of a
Factory in Space (Source: Live Mint)
As the prime mover of Blue Origin, a space venture, he has touched upon
extra-planetary manufacturing as a concept earlier, notably in the
context of a space carrier the company is developing to haul cargo to
the moon. However, a lunar factory was taken as just another
pie-in-the-sky—cool, but a little too dreamy. But what if it can be
done? And what if it actually makes sense?
Consider the state of space rivalry. While Elon Musk’s SpaceX has
lowered flight costs with easily-reusable crafts for space tourism,
Blue Origin is reported to have a strategic edge with heavy payload
lifting, the kind that would be needed to set up a production unit on
some other celestial body. Conceivably, the big set-up challenge would
involve getting equipment up there, exactly what Bezos’s company
appears to be working on. As for land acquisition, while no government
can lay claim to extraterrestrial land and resources under the 1967
Outer Space Treaty, there is nobody out there to enforce it either,
which means that finders get to be keepers. (1/15)
Ohio Will Help US Get
Back to the Moon and Beyond (Source: Columbus Dispatch)
We’re explorers. It’s what humans do. Throughout our history, we’ve
left the relative comfort of our homes in search of resources,
discovery and knowledge. We’ll trek across vast mountains, sail
uncharted oceans, take to the sky and hurtle across the expanse of
space in our never-ending quest to explore. It’s this innate desire
that brings us to the next frontier in human exploration: the Artemis
program and our missions to the moon. Some say we don’t need the moon;
they believe we need to go directly to Mars. But we need the moon if we
are to successfully send humans to Mars.
And unlike Apollo, NASA’s Artemis program will send the first woman and
next man to the moon in 2024 to establish a long-term human presence,
creating a proving ground where we can learn from our closest cosmic
neighbor. There, we’ll better understand how to live and work in deep
space, we’ll develop the tools and processes needed for extended
exploration, and we’ll use the moon’s resources, namely its vast
amounts of ice, to produce the fundamental chemical elements required
for space travel. This lunar education is the only thing that can truly
prepare us for Mars. (1/15)
Scientists Sent Mighty
Mice To Space To Improve Treatments Back On Earth (Source:
NPR)
In early December at the Kennedy Space Center in Florida, two anxious
scientists were about to send 20 years of research into orbit. "I feel
like our heart and soul is going up in that thing," Dr. Emily
Germain-Lee told her husband, Dr. Se-Jin Lee, as they waited arm-in-arm
for a SpaceX rocket to launch. A few seconds later the spacecraft took
off, transporting some very unusual mice to the International Space
Station, where they would spend more than a month in near zero gravity.
Ordinarily, that would cause the animals' bones to weaken and their
muscles to atrophy. But Lee and Germain-Lee, a power couple in the
research world, were hoping that wouldn't happen with these mice. The
couple hope that what they learn from these mice will lead to new
treatments for millions of people with conditions that weaken muscles
and bones. Among those who might eventually benefit: children with
muscular dystrophy or brittle bone disease, cancer patients with muscle
wasting, bedridden patients recovering from hip fractures, older people
whose bones and muscles have become dangerously weak, and astronauts on
long space voyages. (1/16)
Earth Bacteria May Have
Colonized Other Solar Systems (Source: Cosmos)
Could the Earth be a life-exporting planet? That’s the curious question
examined in a recent paper written by Harvard University astronomers
Amir Siraj and Abraham Loeb. The researchers take a novel twist on the
controversial notion of panspermia – the idea, propelled into the
mainstream in the early 1970s by astronomers Fred Hoyle and Chandra
Wickramasinghe, that life might have started on Earth through microbes
arriving from space.
The theory is generally discounted, although eminent astrophysicists
such as Stephen Hawking conceded it was at least possible, and a major
paper published in 2018 revived the topic big-time. In their paper,
Siraj and Loeb reverse the standard assumption about the direction of
the microbial journey and ask whether it is possible to that at some
point Earth-evolved bacteria could have been propelled away from the
planet, possibly to be deposited somewhere else in the Milky Way. (1/16)
China Launches 5G
Satellite (Source: Space News)
China launched an experimental 5G communications satellite Wednesday
night. A Kuaizhou-1A solid launch vehicle lifted off from a mobile
platform at the Jiuquan Satellite Launch Center at 10:02 p.m. Eastern
and placed the Yinhe-1 (Galaxy-1) technology verification satellite
into low Earth orbit. The satellite, developed by Chinese company
Galaxy Space, is expected to test Q/V- and Ka-band communications at up
to 10 gigabits per second. The satellite is part of plans to establish
a global 5G constellation based on the "low-cost, high-performance"
Galaxy-1 small satellite platform. (1/16)
NASA Astronauts Replace
ISS Batteries During 7.5 Hour Spacewalk (Source: Space.com)
Two NASA astronauts replaced batteries outside the International Space
Station during a spacewalk Wednesday. Jessica Meir and Christina Koch
spent seven and a half hours outside the station, resuming work to
replace batteries in the station's power system that had been postponed
when a battery charging unit malfunctioned after an October spacewalk.
The work was successful despite a problem with a camera and light
mounted on Koch's helmet that required Meir to remove it early in the
spacewalk. The two astronauts are scheduled to perform another
spacewalk Monday to complete the battery replacement work. (1/16)
ESA Seeks New Agreement
With European Union (Source: Space News)
The head of the European Space Agency said a priority for him this year
is negotiating a new cooperative agreement with the European Union. Jan
Woerner said he hopes to complete later this year a new financial
framework partnership agreement with the EU governing joint work on the
Copernicus and Galileo programs. EU's next space budget, starting in
2021, is uncertain after a proposal last month to slash the prior
proposed budget of 16.9 billion euros over seven years by up to 25%,
but Woerner said that should not affect ESA's roles in those programs.
Woerner and others added at the meeting they were optimistic the
ExoMars 2020 mission would launch this summer after recent successful
tests of a revised parachute system for the lander. (1/16)
Spire Releases Cubesat
GNSS Data (Source: Space News)
Spire has released the first data from a pair of experimental cubesats.
The two satellites, launched in December, collect Global Navigation
Satellite System (GNSS) reflectometry data, measuring GPS and other
navigation systems' signals that reflect off the Earth's surface. Those
satellites, the company says, can measure soil moisture and ocean wind
conditions, and can serve applications such as weather forecasting,
agriculture, drought monitoring and flood prediction. (1/16)
Treaty's End Could
Jeopardize US. Satellites (Source: Space News)
The end of an arms control agreement could put American satellites in
jeopardy. A report by the Aerospace Corporation released Wednesday
notes that if the New Start arms control agreement is allowed to expire
in 2021, limits on U.S. and Russian nuclear arms will cease as well as
prohibitions on interference with space-based "national technical
means" that are used to verify treaty compliance. The United States
might have to prepare for the possibility that Russia could try to
interfere with both U.S. government and commercial remote sensing
assets, the report argued. It could also mean that, without the on-site
inspections currently allowed under the treaty, space assets will be in
greater demand to monitor Russian nuclear programs, pulling those
satellites away from other uses. (1/16)
Boeing Starliner Will
Require "Minimal" Refurbishment Before Next Mission
(Source: SpaceFlight Now)
The Boeing CST-100 Starliner spacecraft that flew a shortened test
flight last month will need only "minimal" refurbishment before it's
ready for its next mission. Boeing engineers said Wednesday that the
spacecraft, now back at the Kennedy Space Center, shows little external
wear from its two-day orbital flight and likely will need on a modest
amount of work to prepare it for its next mission, a crewed operational
mission to the ISS. The cause of the timer anomaly that caused the
flight to be shortened from more than a week to just two days remains
under investigation. (1/16)

Plant-Powered Sensor
Sends Signal to Space (Source: ESA)
A device that uses electricity generated by plants as its power source
has communicated via satellite – a world first. Such sensors could be
used to connect everyday objects in remote locations, enabling them to
send and receive data as part of the Internet of Things. The device can
inform farmers about the conditions of their crops to help increase
yield, and enable retailers to gain detailed information about
potential harvests. It transmits data on air humidity, soil moisture
and temperature, enabling field-by-field reporting from agricultural
land, rice fields or other aquatic environments. (1/15)
