SpaceX Launches its
Falcon 9 Rocket with 60 Starlink Satellites on Veterans Day
(Source: Parabolic Arc)
A SpaceX Falcon 9 rocket lifted off from the Cape Canaveral Spaceport
on Nov. 11. The rocket carried 60 Starlink communications satellites
for SpaceX. This was the fourth use of the Falcon-9 first stage, and
the second use of the rocket's fairing. Te Falcon 9’s first stage
supported the Iridium-7, SAOCOM-1A, and Nusantara Satu missions, and
the fairing was previously flown on Falcon Heavy’s Arabsat6A mission
earlier this year.
Following stage separation, SpaceX landed the Falcon 9’s first stage on
the “Of Course I Still Love You” droneship, which was stationed in the
Atlantic Ocean. Recovery of the two fairing halves was originally
planned by called off on the day prior to launch. (11/11)
Telesat Postpones
Constellation Manufacturer Selection (Source: Space News)
Telesat will postpone the selection of a manufacturer for its satellite
constellation until next year. Telesat CEO Dan Goldberg said last week
that decision, which had been expected this year, will now come in the
first quarter of 2020. That decision was originally between Airbus
Defence and Space and a team of Maxar Technologies and Thales Alenia
Space, but Maxar and Thales have split and are now competing
separately. Goldberg didn't say in an earnings call if that split was a
factor in Telesat's decision to push back a selection. (11/11)
Kepler Demonstrates Polar
Coverage (Source: SpaceQ)
Kepler demonstrated the ability of its satellite system to provide
high-bandwidth communications in polar regions. The Canadian company
said a German icebreaker participating in a scientific expedition near
the North Pole was able to communicate with Kepler's two demonstration
satellites at a rate of 100 megabits per second. Kepler said the
demonstration showed the potential of its planned constellation to
provide store-and-forward communications of large amounts of data.

New Russian Medium Lift
Rocket Ready in Mid-2020s (Source: Space News)
A new Russian medium-lift rocket won't enter commercial service until
the mid-2020s. GK Launch Services said in a recent interview that the
Soyuz-5 rocket likely won't be commercially available in 2026, with
flight tests scheduled to begin in 2023. The current design of the
vehicle makes use of versions of existing rocket engines, including the
RD-171 engine in its first stage, and launches from Baikonur will use
facilities originally developed for the Zenit rocket. The Soyuz-5 will
be able to place up to 17.3 tons in low Earth orbit and 5 tons in
geostationary transfer orbit, but the company isn't disclosing a price
for the rocket. (11/11)
Space Industry Works with
Government in New Info Sharing Center (Source: C4ISR
& Networks)
The acknowledgement of space assets as critical infrastructure has
enabled the establishment of the Space Information Sharing and Analysis
Center to help ward off cyberthreats. "We think this is a great
opportunity for us to be able to bring some of that expertise in -- in
how you protect data and how you move data around and the threats that
go along with that -- to the ISAC," said Chris Bogdan, who leads Booz
Allen Hamilton's aerospace unit.
There are about two dozen ISACs within the US. These nonprofit
organizations essentially act as an industry go-between, sharing
knowledge about cybersecurity and other threats. “Because these ISACs
are sector-focused and member-driven, they can select the specific
cyberthreat information and perform analysis on what is particularly
relevant to the industry in which the members operate.” But until this
year there was no ISAC dedicated to space. (11/8)
NASA Scientists Detect
Huge Thermonuclear Blast Deep in Space (Source: Science
Alert)
NASA recently detected a massive thermonuclear explosion coming from
outer space. The culprit seems to be a distant pulsar, the space agency
reports, which is the stellar remains of a star that blew up in a
supernova but was too small to form a black hole. NASA spotted the
burst because it sent out an intense beam of x-rays that got picked up
by the agency's orbital observatory NICER. All in all, it serves as a
potent reminder: space is an extremely dangerous, extremely metal
place. (11/10)
Virgin Galactic’s IPO
Launches a Pivotal Phase for Space Tourism (Source: Quartz)
The route to success in the space tourism industry is bound to be a
wild ride and Branson is hoping his first mover advantage will bring
healthy returns in the long run. Indeed, this high-risk venture could
well pay off–it’s just a question of when. Although it has yet to fly
any paying passengers and is currently loss making, Virgin Galactic
aims to be profitable by 2021, based on completing 115 flights that
generate $210m in revenue. By 2023, it is forecasting revenues of $590m
and expects to have flown more than 3,000 passengers.
Since that number is a tiny portion of the target market of high
net-worth individuals with assets of at least $10m, its projections
could well be achievable. And, currently, Virgin Galactic appears to be
ahead of Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin in fulfilling
the vision of space tourism. While Virgin Galactic has failed to
deliver on expectations in the past–it missed its own targets for
flights commencing and experienced a catastrophic accident in 2014–it
has more recently made substantial progress. (11/8)
University of Florida Lab
Investigates Space Debris (Source: MIT Technology Review)
On a sweltering day in August, in a windowless strip mall office in
north-central Florida, Rafael Carrasquilla and a dozen other students
wore surgical gloves as they picked through piles of dust with
tweezers. They were hunting for tiny slivers of carbon fiber only
millimeters long, almost invisible to the naked eye. There were no
ventilation fans, no sneezing or sudden movements at the lab bench.
When they found one, they logged its appearance in a database, bagged
it, tagged it, and placed it among tens of thousands of others
painstakingly organized in ranks of plastic bins.
Carrasquilla leads the fragment characterization effort for the
University of Florida, part of a NASA-led experiment called DebriSat
that began in 2011. DebriSat was created to answer a question: What
happens when a piece of orbital debris slams into a satellite at
thousands of miles per hour? If such a collision occurs in orbit, it’s
impossible to keep track of the resulting chaos. The only way to answer
that question with confidence is to cause a catastrophic impact in a
laboratory down here on Earth, where conditions can be carefully
controlled and results meticulously catalogued.
Orbital debris comes in many shapes and sizes, from fragments similar
to those Carrasquilla’s group was analyzing to full-size rocket
boosters left in space. In orbit, even miniature fragments are capable
of damaging satellites or penetrating space suits. Kinetic energy
increases with the square of an object’s velocity—and impacts in orbit
typically happen at over 20,000 miles per hour, so that even tiny
carbon-fiber needles can cause damage. “The biggest mission-ending risk
to operational spacecraft comes from small, millimeter-size orbital
debris, not big fat objects,” says NASA's Jer Chyi “JC” Liou. Click here.

There’s Growing Evidence
That the Universe Is Connected by Giant Structures
(Source: Motherboard)
Galaxies within a few million light years of each other can
gravitationally affect each other in predictable ways, but scientists
have observed mysterious patterns between distant galaxies that
transcend those local interactions. These discoveries hint at the
enigmatic influence of so-called “large-scale structures” which, as the
name suggests, are the biggest known objects in the universe. These dim
structures are made of hydrogen gas and dark matter and take the form
of filaments, sheets, and knots that link galaxies in a vast network
called the cosmic web.
We know these structures have major implications for the evolution and
movements of galaxies, but we’ve barely scratched the surface of the
root dynamics driving them. Scientists are eager to acquire these new
details because some of these phenomena challenge the most fundamental
ideas about the universe. “That’s actually the reason why everybody is
always studying these large-scale structures,” says Noam Libeskind, a
cosmographer. “It’s a way of probing and constraining the laws of
gravity and the nature of matter, dark matter, dark energy, and the
universe.”
For instance, a study published in The Astrophysical Journal in October
found that hundreds of galaxies were rotating in sync with the motions
of galaxies that were tens of millions of light years away. “This
discovery is quite new and unexpected,” said lead author Joon Hyeop
Lee, an astronomer at the Korea Astronomy and Space Science Institute,
in an email. “I have never seen any previous report of observations or
any prediction from numerical simulations, exactly related to this
phenomenon.” (11/11)
The Space Artist Who Saw
Pluto Before NASA (Source: Guardian)
On 7 November, David Hardy opens a new exhibition called Visions of
Space alongside 19 fellow space artists. Space art (or astronomical
art) is an art movement just like modernism or impressionism. Its early
pioneers included American artist , who painted what he saw in a
telescope, and French astronomer-artist Lucien Rudaux, who made an
atlas of the Milky Way – and created impossibly accurate paintings of
Mars in the 1920s and 1930s. Together, they’re known as the Fathers of
Modern Space Art. Click here.
