A new video shows a view of the sun that's so strange you'd think it
came from a science fiction horror film. The "skin" of the sun — also
known as the photosphere — pulses and morphs in an active region of
solar granules imaged by a Swedish telescope. "These granules are the
tops of convection cells where hot gas rises from the interior to cool,
and then descends back down," NASA explained in a statement. Click here.

SpaceX Faces Daunting
Challenges if it’s Going to Win the Internet Space Race
(Source: LA Times)
Elon Musk and SpaceX have staked their legacy on a spaceship capable of
carrying a hundred passengers to Mars. But to pay for that dream, the
Hawthorne company is banking on a project that is ambitious in its own
way: selling broadband internet service delivered by more than 1,000
small satellites.
Chief Executive Musk has mused to reporters about the technological
hurdles facing SpaceX’s Starlink constellation, including antennas that
track the satellites as they move through the sky and laser
communication systems that allow the spacecraft to talk to each other.
Last month, SpaceX launched the first 60 satellites of its planned
constellation.
But industry experts say the company’s biggest challenge is financial.
SpaceX must drive down the cost of sophisticated hardware and software
to the point where it can deliver fast, reliable internet service at a
price point that competes with cable or fiber-delivered broadband
services, while finding enough underserved markets to provide scale.

Branson Ready to Risk
Life to Make Space Dreams Real (Source: Daily Beast)
Richard Branson is finally close to riding his rocket ship. After a
decade in which he repeatedly announced his imminent departure into
space as the first passenger aboard Virgin Galactic’s SpaceShipTwo,
only to then call it off, it seems that the ship is ready. And Branson,
ever the showman, aims to time his ride to coincide with the most
epochal date in the history of space travel. Earlier this year he
announced his intention to lift off on or close to July 20, the 50th
anniversary of Apollo 11’s landing on the moon.
That would certainly be an act of chutzpah. The Apollo program went
from conception to the moon landing in eight years. Branson originally
promised his ship would be ready for lift-off with passengers in 2009,
and we’re still waiting. Technically, Virgin Galactic is no moonshot.
It is a project of far lower ambition and aimed at a fundamentally
frivolous purpose. For years it has been way overhyped. (6/27)
NASA Picks Dragonfly
Mission to Titan (Source: Space News)
NASA announced Thursday it selected the Dragonfly mission to Titan as
its next New Frontiers mission. Dragonfly will launch in 2026 and
arrive at Titan, Saturn's largest moon, in 2034. The spacecraft,
equipped with eight rotors, will be able to fly through Titan's dense
atmosphere, traveling from a landing site near the moon's equator to a
large crater 175 kilometers away over the course of two and a half
years. Scientists will use Dragonfly to better understand Titan's
composition and chemistry, which contains the building blocks for life
much like the early Earth. NASA said it selected Dragonfly after
addressing a number of technical risks with the original proposal for
the mission. Dragonfly beat out CAESAR, a comet sample return mission.

Senate Bill Authorizes
Space Force Creation (Source: Space News)
The Senate approved its version of a defense authorization bill,
including language creating a U.S. Space Force. The Senate on Thursday
passed its version of the National Defense Authorization Act for Fiscal
Year 2020 by a vote of 86–8. The Senate approved a space organization
that is somewhat different than what was passed by the House Armed
Services Committee, which proposed a Space Corps within the Air Force.
Both chambers will have to hammer out a compromise on final NDAA
language before a new space service is enacted, but a Pentagon official
was optimistic that some version of a Space Force will emerge in the
final version of the bill. (6/28)

Houston Airport System to
Break Ground on Spaceport Project (Source: Houston
Business Journal)
Phase 1 of the Houston Spaceport broke ground on June 28. The Houston
Airport System celebrates the groundbreaking of phase 1 — an $18.8
million project. The scope of the project’s first phase includes
streets, water, wastewater, electrical power and distribution, fiber
optics and communications facilities. The first phase will also include
the construction of 53,000 square feet of lab and office space,
according to the HAS website. Some 154 acres of land are set aside for
phase 1.
Texas Sterling-Banicki JV LLC, a joint venture, is developing the
infrastructure for the spaceport, according to a building permit filed
with the city of Houston and previous Houston Business Journal
reporting. JV partners Houston-based Texas Sterling Construction Co.
and Phoenix-based Banicki Construction are both subsidiaries of
Sterling Construction Co. More than $13.1 million of the $18.8 million
will cover TSB’s preconstruction and design services as well as
construction services for the infrastructure work.
The first company to sign on as a spaceport tenant — Houston-based
Intuitive Machines — is already underway on lunar lander and drone
technology. On May 31, Intuitive Machines received a $77.2 million
contract from NASA to develop, launch and land its Nova-C spacecraft on
the lunar surface. The company is on track to be the first private U.S.
firm to land a spacecraft on the moon during a planned 2021 mission.

NASA Moon Landing
Warning: Humans At Risk From Crippling Illness Caused by Lunar Dust
(Source: Express)
Humans may be allergic to lunar dust, the last living man to walk on
the Moon has claimed after revealing illness sustained after the final
NASA Apollo mission. Scientist Harrison ‘Jack’ Schmitt was part of the
last Apollo mission to the Moon in 1972 shortly before the program was
shelved. Mr Schmitt was the only scientist to get the opportunity to
walk on the satellite. He spent hours collecting dust and samples from
the Moon’s surface.
But when he returned to the landing module, dust which had collected on
his spacesuit became inhaled, causing an immediate reaction. He told
the Starmus space festival in Zurich that the “inside of my nose became
swollen” and that the allergic reaction could be “heard in my voice”.
Ms Schmitt said: “But that gradually that went away for me, and by the
fourth time I inhaled lunar dust I didn’t notice that. “Whereas a
flight surgeon taking suits out of the Apollo 17 command module, after
we had splashed down, he had such a reaction that he had to stop doing
what he was doing. (6/27)
Want to Live on the Moon?
Try Living Under a Swiss Glacier First (Source: Space.com)
This month, about 50 feet (15 meters) under a Swiss glacier, you can
experience what it might be like to live on the moon. To offer an idea
at what such a habitat might look like, European researchers and
students are conducting a mock moon habitat trial under a glacier near
the famous Matterhorn in Switzerland's Alps.
Called IGLUNA, the demonstration is organized by the Swiss Space Center
and the European Space Agency. Teams from across Europe arrived in the
car-free mountain town of Zermatt, Switzerland, last week to set up
their experiments, which include an ice-digging robot, a construction
robot, an algae bioreactor and a hydroponic system for growing veggies.
They've also built a habitat 8.5 feet (2.6 meters) tall buried deep in
the ice. (6/27)
Startup Shares Disaster
Imagery, But at What Cost? (Source: Space News)
Government space agencies and multinational corporations have
well-established mechanisms in place to respond to requests for imagery
in the wake of fires, floods or other disasters.. For Iceye, the
Finnish firm that launched the first small radar satellite in 2018, the
frequent requests pose challenges. “There is something happening every
day: earthquakes, floods, fires, landslides, avalanches,” said Rafal
Modrzewski, Iceye founder and chief executive. People fill in forms on
Iceye’s website and the company tasks its Iceye-X2 synthetic aperture
radar satellite to capture the imagery.
“There is no situation in which we would charge people for [this]
data,” Modrzewski said. Still, Iceye is a new company that needs to
make money in order to survive. Perhaps governments should provide some
type of support to ensure companies like Iceye can continue sharing
geospatial data in the wake of disasters, he added. “The problem is no
one thinks about disasters before they happen,” Modrzewski said. “We
are there to provide data when they do. We may not be there unless
governments realize they have to support us.” (6/28)
Astronomers Have Decoded
a Weird Signal Coming from a Strange, 3-Body Star System
(Source: Live Science)
Once or twice a day, a strange object in the Milky Way blinks at us.
Now, astronomers think they know why. The object is called NGTS-7, and
to most telescopes it looks like a single star. Researchers at the
University of Warwick in England started watching because it seemed to
be emitting flares, but on closer examination they noticed that its
starlight dims briefly every 16.2 hours. When the astronomers zoomed
in, they realized there are actually two similarly sized stars in the
system, and that only one of them is dimming briefly in that way —
suggesting that there's something dark circling on or just above the
star's surface. (6/27)

New Era of Supersonic
Travel May End Before It Even Begins (Source: Bloomberg)
The dream of flying passengers faster than the speed of sound gave
birth to Concorde in the 1970s, only for the nightmare of making a
profit to snuff it out less than three decades later. Companies
competing to build a successor to the iconic jet may find that the
biggest hurdle isn’t technology or economics, but the hefty carbon
footprint that’s the result of such eye-watering speeds -- especially
with mainstream plane and engine makers saying electric airliners may
soon be within reach.
Driven by mounting public and political concerns about aviation
emissions, the new-found environmental zeal of manufacturers such as
Airbus SE threatens to make startups intent on breaking the sound
barrier look like relics from a greedier age that spared little thought
for the the environment. That’s despite advances in aerodynamic design,
materials and propulsion that have brought a second supersonic era
tantalizingly close. Those concerns were on display at last week’s
Paris Air Show, where Boom Technology Inc., which is working to
introduce a 75-seat, Mach 2.2 jetliner, went out of its way to assert
the plane’s green credentials. (6/28)

Astronomers Discover the
Source of Unexplained Cosmic Radio Burst (Source: C/Net)
The burst was picked up by the Australian Square Kilometer Array
Pathfinder, which consists of 36 radio telescopes working in tandem to
scan the sky and listen for radio signals. Situated in the Australian
outback, where there's little radio interference, ASKAP is able to pick
up the faintest whispers of the universe. The burst traveled from the
other side of the universe, smacking into ASKAP's array -- and within
half a second, the machine stopped the search and downloaded the data
from each of the 36 dishes.
The burst hits each dish at slightly different times. In a ridiculous
feat of engineering, the team can calculate the difference in arrival
time to within one-tenth of a nanosecond. That allows their detective
work to begin, tracing the position to a spot in the sky -- essentially
plucking a needle from a haystack. The research team found FRB 180924
had come from a distant galaxy very similar in size to our own Milky
Way. Galaxies are huge, huge swirling masses of stars, but the team was
able to pinpoint the burst's exact cosmic city block, approximately
13,000 light-years from the center of the galaxy.
On only one other occasion, in 2017, has a fast radio burst been traced
to its source -- and that particular investigation was slightly easier
because the burst repeated itself intermittently, like a strobe light.
Known as FRB 121102, or the "repeater," the burst came from a
completely different source to FRB180924: a dwarf galaxy slightly
around 3 billion light-years away. That suggests non-repeating fast
radio bursts might be different from those that do repeat, or it could
hint that the signal differs depending on where it comes from. (6/27)
