How Many Alien Civilizations are Out
There? A New Galactic Survey Holds a Clue (Source: National
Geographic)
More than 300 million worlds with similar conditions to Earth are
scattered throughout the Milky Way galaxy. A new analysis concludes
that roughly half of the galaxy’s sunlike stars host rocky worlds in
habitable zones where liquid water could pool or flow over the planets’
surfaces. “This is the science result we’ve all been waiting for,” says
Natalie Batalha, an astronomer with the University of California, Santa
Cruz, who worked on the new study.
The finding, which has been accepted for publication in the
Astronomical Journal, pins down a crucial number in the Drake Equation.
Devised by my father Frank Drake in 1961, the equation sets up a
framework for calculating the number of detectable civilizations in the
Milky Way. Now the first few variables in the formula—including the
rate of sunlike star formation, the fraction of those stars with
planets, and the number of habitable worlds per stellar system—are
known. (11/2)
Airbus Wins Satellite Mission to Gauge
Global Warming Accuracy (Source: Bloomberg)
Airbus SE won a contract to help build a European Space Agency
satellite designed for scientists to more accurately predict the pace
of climate change. The mission will enlarge the constellation of
satellites being launched to track the impact of global warming on the
Earth’s economies. The Traceable Radiometry Underpinning Terrestrial
and Helio Studies, or TRUTHS satellite, will increase the certainty of
climate and weather models. It will follow recent launches of
satellites observing air quality, emissions and sea levels. (11/2)
Vector Restarting Operations Under New
Ownership (Source: Space News)
Vector, a small launch vehicle developer that went bankrupt in 2019, is
getting a second chance under new ownership, with changes to both its
technology and initial markets. Vector has raised more than $100
million to develop a family of small launch vehicles, but suspended
operations in August 2019 and laid off most of its employees after one
of its key investors pulled out. The company filed for Chapter 11
bankruptcy in December and later decided to sell its assets.
Vector’s satellite assets, called GalacticSky, were acquired by
Lockheed Martin in February for $4.25 million. Vector’s launch assets
were sold in May to an entity known as TLS Bidco LLC for $1.175
million, according to bankruptcy court filings. The new owner of
Vector’s launch assets is a consortium led by John Moran, president and
chief executive of Moran Logistics, a shipping company based in
Pennsylvania. They are restarting Vector with Robert Spalding, a
retired Air Force brigadier general who previously served on the staff
of the National Security Council, as chief executive.
One thing they [previously] did wrong was the technology the used for
their engines. “They had some Achilles’ heels associated with their
technical approach. They were trying to use a propellant combination
[propylene and liquid oxygen] that was untested in the industry,” said
Chris Barker, who serves as Vector’s chief rocket scientist. “They were
struggling with trying to get performance that they knew they needed
for a small launcher to be successful, and ultimately their test
program was unsuccessful.” (11/3)
Space Command Concerned About China
and Russia Weaponizing Space (Source: Space News)
The new head of U.S. Space Command says he wants to keep space safe
from emerging threats he sees from China and Russia. In his first
interview since taking over Space Command, U.S. Army General James
Dickinson said he is concerned those two countries "have weaponized
space" and that he will continue to publicly reprimand space activities
by those countries that are unsafe or unprofessional. Dickinson said he
supports the transition of civil space traffic management activities to
the Commerce Department, and is working with the department on those
transition plans. Another priority, he added, is making clear the
difference between Space Command and the U.S. Space Force, the new
military service. (11/2)
UK's Spacebit Seeks Research Partners
for Lunar Rover (Source: Space News)
Spacebit is looking for research partners for its first lunar rover.
The U.K.-based company has plans to send two small rovers to the moon
on commercial lander missions by Astrobotic and Intuitive Machines in
2021. The company said it will release images and other data those
rovers collect to scientists after an initial analysis within the
company. Spacebit's founder said that flying two rover missions
provides a degree of redundancy and, if both are successful, enables
studies of two different regions of the moon. (11/3)
Space Force and ARFL Aim for Cislunar
Space (Source: Space News)
The Space Force might operate in cislunar space in the near future. The
Air Force Research Laboratory (AFRL) is working on a mission concept
called Cislunar Highway Patrol System, or CHPS, intended to monitor
cislunar space. Details of the experiment are nowhere close to being
decided, though, and AFRL plans to solicit ideas from the private
sector and assess different technologies and approaches some time next
year. The CHPS project is driven by growing interest by the Space Force
for expanding its responsibilities beyond geostationary orbit. (11/3)
Commercial Constellation Poses Threat
to NASA Earth Observation Satellites (Source: Ars Technica)
NASA has raised concerns about a proposed commercial satellite
constellation. In a filing with the FCC, NASA said the SpaceMobile
constellation of 240 large satellites proposed by AST&Science poses
a risk to its "A-Train" of Earth observations satellites, which are in
orbits near those of the SpaceMobile system. The large size of the
SpaceMobile satellites would increase the number of conjunctions that
NASA will have to deal with, creating an "unacceptably high" risk of
collisions. The company said it is confident it can work out ways to
mitigate those risks. AST&Science is also facing strong opposition
from terrestrial mobile operators, who argue the system could interfere
with their networks. (11/3)
Rocket Lab Readies 30-Satellite Launch
(Source: Stuff.co.nz)
Rocket Lab's next launch will carry 30 satellites — and a gnome. The
company said Monday that an Electron launch scheduled for mid-November
will carry 30 satellites, 24 of which will be Spacebee satellites for
Swarm's internet of things constellation. Other payloads include two
satellites for Unseenlabs, a French company developing a constellation
for radio-frequency monitoring, and a demonstration of a tether-based
deorbiting system. Mounted on the rocket's kick stage will be a
3D-printed gnome, a project funded by Gabe Newell, founder of game
company Valve. The gnome, named Gnome Chompski, is a character in the
"Half-Life" series of games by Valve, and is intended to be a test of
new 3D-printing technologies that could be used in future satellites.
Newell said he will donate $1 to a children's hospital for each person
who watches the livestream of the launch. (11/3)
UK Apprenticeship Program Builds Space
Workforce (Source: Space Daily)
The UK's Space Engineering Technician apprenticeship is the first to be
recognised by the Institute for Apprenticeships and Technical Education
(IfATE) and approved by The Department of Education. The first cohort
of students is expected to start their training from January 2021. The
UK space sector is hungry for engineers and technologists who
understand the demands that come with working in space, and over the
next decade the sector aims to create 30,000 jobs. This new opportunity
will offer students, for the first time, the chance to focus on topics
like spacecraft manufacturing; building skills in design, problem
solving and testing.
Currently, apprentices training in space roles gain qualifications as
general apprentices and craft apprentices. The Science Minister
recently visited Airbus in Stevenage where she met apprentices working
on satellite panel manufacturing, as well as those developing
techniques to be used by the Rosalind Franklin the Mars sample fetch
rover. Science Minister Amanda Solloway said: "This new qualification
is an incredible opportunity for young people which will equip them
with the vital skills they need to help unlock the secrets of our solar
system. "The UK's space industry is booming, and these new apprentices
will become the next generation of engineers that will help us achieve
our country's space ambitions." (11/2)
