SpaceX Starlink
Satellites Dazzle But May Cause Headaches for Astronomers
(Source: CNET)
The first batch of satellites were launched from Cape Canaveral,
Florida, and deployed to orbit by a Falcon 9 rocket on May 23. Each
contains a single solar array, which both captures and bounces sunlight
off the satellites and, as a result, can sometimes be seen from Earth.
In time, the satellites will drift apart and head to specific orbits so
that satellite internet coverage can be beamed to every corner of the
globe.
However, as the unusual display in the night sky quickly gathered steam
across social media, some astronomers began to point out the potential
problems the satellite system may pose for astronomy. At present, only
60 satellites are moving into their orbit, but eventually that number
will reach 12,000, and a megaconstellation will encircle the Earth.
Practically overnight, our view of the sky has changed.
Starlink would triple the number of satellites orbiting the Earth. If
thousands of satellites are sent into orbit, our view of space changes.
Will we find ourselves in a position where it's impossible to
investigate the cosmos from the ground? Potentially. Bright, reflective
surfaces pose a problem because they obstruct our view of the universe.
More satellites equals cloudier vision, and Starlink plans to launch
more satellites than ever. (5/28)
Russian Space Sector
Plagued by Corruption (Source: Space Daily)
With millions of dollars missing and officials in prison or fleeing the
country, Russia's space sector is at the heart of a staggering
embezzlement scheme that has dampened ambitions of recovering its
Soviet-era greatness. For years, Moscow has tried to fix the industry
that was a source of immense pride in the USSR. While it has bounced
back from its post-Soviet collapse and once again become a major world
player, the Russian space sector has recently suffered a series of
humiliating failures.
And now, massive corruption scandals at state space agency Roscosmos
have eclipsed its plans to launch new rockets and lunar stations.
"Billions (of rubles) are being stolen there, billions," Alexander
Bastrykin, the powerful head of Russia's Investigative Committee --
Russia's equivalent of the FBI -- said in mid-May. (5/28)

Blue Origin, Boeing and
Other Ventures Lay Out Ideas for Commercial Space Stations
(Source: GeekWire)
Amazon CEO Jeff Bezos’ Blue Origin space venture has laid out a plan
for building a commercial habitat for future space travelers and
sending it into Earth orbit atop its New Glenn rocket. The concept is
one of a dozen studies that NASA released today as part of a project to
assess how crewed space operations in low Earth orbit, or LEO, could be
commercialized within the next six years or so.
NASA commissioned the studies last summer to investigate commercial
alternatives to the International Space Station, in line with the
current plan to move away from government management and operation of
the space station’s U.S. segment by 2025. Each of the 13 teams was
tasked with providing a study at a cost of no more than $1 million,
with the total price tag for the study project estimated at $11
million. Click here.

SpaceX Raises Over $1
Billion Through Two Funding Rounds (Source: Space News)
SpaceX has raised over $1 billion in new capital this year as it
embarks on the deployment of its Starlink broadband constellation,
according to regulatory filings published Friday. The launch provider
turned satellite operator raised $486.2 million in one round, and
$535.7 million in another, the company said in May 24 filings to the
U.S. Securities and Exchange Commission. The filings show SpaceX sold
all but $18.8 million of the shares available between the two rounds.
The company raised $1.022 billion in total.
SpaceX is currently building two capital-intensive projects — the fully
reusable Super Heavy booster with its Starship upper stage, and the
Starlink broadband megaconstellation of up to 12,000 satellites. SpaceX
CEO Elon Musk said in 2017 that the plan for funding Starship and Super
Heavy — then called the Big Falcon Rocket — involved replacing SpaceX’s
current Falcon 9 and Falcon Heavy rockets with the new launch system.
In a call with reporters last week, Musk said SpaceX believes it can
also use Starlink revenue to fund the new launch system. (5/24)
Astronauts Are Heading
Under the Sea Off Florida's Coast to Test Moon Mission

An astronaut-led crew will go underwater to get ready for human moon
missions. The 10-day NASA Extreme Environment Mission Operations
(NEEMO) 23 expedition is scheduled to begin June 10 and will test
technologies NASA will use for lunar missions that could come as soon

Among the crew goals is testing scien8)ce instruments and tools for
work on the moon, including items that will help get "core samples" — a
cylindrical cross-section of the moon's geology just below the surface
— NASA officials said in a statement. Apollo astronauts who did lunar
missions (between 1969 and 1972) obtained several core samples using a
special device called the Apollo Lunar Surface Drill.
The mission also includes work that is useful for a variety of
deep-space destinations, including tracking sleep and using augmented
reality to train crewmembers in navigating their habitat. Astronauts
will live and work in the Aquarius laboratory, which is located 62 feet
(19 meters) below the ocean surface near Key Largo, Florida. They will
also venture outside the habitat to explore the nearby underwater
environment. (5/28)

UFOs Exist and Everyone
Needs to aAdjust to That Fact (Source: Washington Post)
The term “UFO” automatically triggers derision in most quarters of
polite society. One of Christopher Buckley’s better satires, “Little
Green Men,” is premised on a George F. Will-type pundit thinking that
he has been abducted by aliens, with amusing results. UFOs have
historically been associated with crackpot ideas like Big Foot or
conspiracy theories involving crop circles.
The obvious reason for this is that the term “UFO” is usually assumed
to be a synonym for “extraterrestrial life.” If you think about it,
this is odd. UFO literally stands for “unidentified flying object.” A
UFO is not necessarily an alien from another planet. It is simply a
flying object that cannot be explained away through conventional means.
Because UFOs are usually brought up only to crack jokes, however, they
have been dismissed for decades.
One of the gutsiest working paper presentations I have witnessed was
Alexander Wendt and Raymond Duvall presenting a draft version of
“Sovereignty and the UFO.” In that paper, eventually published in the
journal Political Theory, Wendt and Duvall argued that state
sovereignty as we understand it is anthropocentric, or “constituted and
organized by reference to human beings alone.” They argued that the
real reason UFOs have been dismissed is because of the existential
challenge that they pose for a worldview in which human beings are the
most technologically advanced life-forms. Click here.

Here's How Scarily
Accurate NASA's Long-Term Climate Predictions Have Been So Far
(Source: Science Alert)
Every year, NASA partners with the NOAA to update the global
temperature. They use temperature data dating back to 1880 from land
and sea surface measurements, combined with more modern measurements
from over 6,300 weather stations research stations, and ships and
weather buoys around the world. Using all this data, the pair of
organizations concluded that 2018 was the fourth-warmest year on
record, and that 2016 was the warmest.
NASA scientists analyzed the GISTEMP data to see if past predictions of
rising temperatures were accurate. They needed to know that any
uncertainty within their data was correctly accounted for. The answer:
Yes they are. Within 1/20th a degree Celsius. This is scientific rigour
at its finest. And they acknowledge, like all scientists should, any
weakness in their own data and then seek to quantify it. The NASA
analysis ferreted out four sources of uncertainty, however miniscule,
in the GISTEMP data.
The first is how temperature measurement changed over time, and it
contributes the most uncertainty. Second was weather station coverage.
You can't have a weather station at every point on Earth, so you have
to interpolate the data. That interpolation is the third largest source
of uncertainty, though it's contribution to uncertainty was tiny.
Lastly was how the collected data was standardized over different time
periods in history. (5/28)

The provisions require the Defense Department to lay out a plan for how
it could make greater use of commercial spaceports to launch small
satellites and to develop a strategy to integrate commercial
capabilities into DoD space operations. The provisions, if they make
into the final version of the bill, would address longtime concerns of

satellite deployment scenario could mean that SpaceX will be able to
start offering Starlink service to consumers “in the Northern U.S. and
Canadian latitudes” as early as this year, while commercial offerings
would thus be all but guaranteed in 2020. A step further, SpaceX
