Further Evidence Of 200 Million-Year
Cycle For Earth’s Magnetic Field (Source: Eurasia Review)
The findings of a new study by the University of Liverpool provides
further evidence of an approximately 200-million-year long cycle in the
strength of the Earth’s magnetic field.
Researchers performed thermal and microwave (a technique which is
unique to the University of Liverpool) paleomagnetic analysis on rock
samples from ancient lava flows in Eastern Scotland to measure the
strength of the geomagnetic field during key time periods with almost
no pre-existing, reliable data. The study also analysed the reliability
of all of the measurements from samples from 200 to 500 million years
ago, collected over the last ~80 years.
They found that between 332 and 416 million years ago, the strength of
the geomagnetic field preserved in these rocks was less than quarter of
what it is today, and similar to a previously identified period of low
magnetic field strength that started around 120 million years ago. The
researchers have coined this period “the Mid-Palaeozoic Dipole low
(MPDL).” (8/21)

Space Beer: Hops Flying on
Inspiration4 Mission Will be Auctioned for Charity (Source:
Space.com)
Billionaire Jared Isaacman is looking for a brewery to make beer with
space-flown hops — for a good cause. The tech entrepreneur and
experienced pilot has chartered a SpaceX flight to send himself and
three other passengers, all private citizens, into orbit for a
three-day mission in a Crew Dragon spacecraft. Called Inspiration4, the
mission is scheduled to lift off Sep. 15 from Florida.
Hitching a ride to space with the Inspiration4 crew will be 70 pounds
(32 kilograms) of hops, an ingredient that adds bitterness and aroma to
beer. And when that hops returns to Earth, Isaacman plans to auction it
off to a brewery and donate the funds to St. Jude Children's Research
Hospital, he announced on Twitter Aug. 12, adding that interested
breweries should "inquire on inspiration4.com." (8/20)
Private Firms Are the Key to Space
Exploration (Source: National Review)
Like most NASA programs, the ISS is massively over budget. Costs were
initially projected at $12.2 billion, but the bill ultimately reached a
stunning $150 billion. American taxpayers paid around 84 percent of
that. What happened to the American dream of human space exploration?
Put simply, the government happened. NASA devolved into a jobs program
to bring home the space bacon.
It is hard to imagine a better example of the private sector’s amazing
ability to outcompete government bureaucracy and mismanagement than
NASA’s planned Shuttle replacement, the SLS. It is estimated to cost
more than $2 billion per flight. That’s on top of the $20 billion and
nine years the agency has already spent developing it. Contrast that
with the $300 million spent by SpaceX to develop the Falcon 9 in a
little over four years, and the fact that each Falcon 9 costs around
$62 million. One SLS launch could pay for over 32 SpaceX launches.
Aerospace experts expect that establishing a $10 billion prize for
successfully landing a crew on Mars and returning it safely to earth
could very well lead to a successful landing. That’s a bargain compared
with the $500 billion cost estimates NASA puts out for the same
objective. And of course in the worst-case failure scenario for a prize
program, taxpayers would pay nothing until the mission was complete. A
system based on private enterprise incentivized by a fixed prize would
end government cost overruns and waste. (8/21)
Colorado Officials React to Trump's
Statement He Was Personally Responsible for Space Command HQ Move to
Alabama (Source: KKTV)
In an interview on Friday, former President Donald Trump said he
“single-handedly” picked Alabama as the new home for U.S. Space
Command.” The announcement by the former president confirmed earlier
reports. Back in January, the U.S. Air Force announced Redstone Arsenal
in Alabama as the preferred location for Space Command HQ. Currently,
the command is housed at Peterson Space Force Base in Colorado .
Colorado leaders were disappointed in the decision to move Space
Command to Alabama and even questioned the selection process. “Colorado
is the natural home for Space Command,” Gov. Polis and Lt. Governor
Primavera said in a joint statement. “These callous comments fly in the
face of Coloradans, military families, and those who have worked to
cultivate our aerospace ecosystem that is suited to guarantee the
operational success of U.S. Space Command and deliver the best value to
taxpayers."
"Keeping U.S. Space Command in Colorado means protecting our national
security but it’s clear that the former President - now through his own
admission - made this misguided decision for political or personal
purposes. Unfortunately, this poor decision could cost taxpayers
billions of dollars, hurt military readiness, and would be fiscally
irresponsible. We urge the federal government to truly restore
integrity to the process.” (8/21)
Musk’s Space Push Forces Satellite
Rivals Into Merger Mode (Source: Bloomberg)
Plans by Elon Musk and Jeff Bezos to launch thousands of satellites
into orbit are forcing an industry that’s traditionally wary of mergers
to prepare for consolidation. The billions of dollars that Musk
is pouring into his Starlink broadband internet service are skewing the
economics of space for companies like SES SA, the world’s
second-biggest satellite operator by sales.
The growth of streaming over fiber optic networks threatens another of
their mainstays -- satellite TV. Takeovers, investments and joint
ventures in the industry this year have already surpassed 2020, with
more than $3.6 billion spent on them so far in 2021. ViaSat Inc.
Chairman Mark Dankberg said there “certainly is discussion” in the
industry about mergers. “One of the reasons for consolidation would be
to try to divert more capital funding from broadcast into
broadband.”
Although industry executives downplay the threat from Musk, they are
adapting. Companies such as Inmarsat Holdings Ltd., ViaSat, Eutelsat SA
and Telesat LLC plan to launch high-throughput or low-latency
satellites to offer their own broadband services to businesses and
homes. But each launch is an expensive bet that clients won’t defect to
other technologies. Combining forces would make these rollouts more
efficient. (8/20)
Colorado Pushes for Reversal of Space
Command Move Following Trump Comments (Source: KOAA)
"By the way, Space Force I sent to Alabama, I hope you know that,"
Trump said on the broadcast. "Yeah, and they said, we're looking for a
home and I single-handedly said let's go to Alabama. They wanted it, I
said let's go to Alabama." Colorado Springs Mayor John Suthers has long
believed the January decision was based on politics.
"I guess I'm not surprised, I'm glad that he admitted it because now we
can say to the Air Force we can say to DOD and everybody else this was
not the merit-based process that some people pretended that it was,"
Colorado Springs Mayor John Suthers said.
Congressman Doug Lamborn also pointed to the president's statement as
an admission that the decision was based on politics and personal
preference and not the Air Force's basing criteria. "This proves that
claims by the Department of the Air Force that the decision was
'merit-based' are completely false," Lamborn wrote. (8/21)
Space Force Strikes Deal with
University of Colorado (Source: USSF)
The U.S. Space Force expanded its University Partnership Program at the
University of Colorado during a Memorandum of Understanding signing
event Aug. 20. Vice Chief of Space Operations Gen. David D. Thompson
joined University of Colorado President Todd Saliman on the UC Colorado
Springs campus to sign the MOU.
“The state of Colorado and community of Colorado Springs have long been
key members and supporters of the national security space enterprise,
so it’s fitting for the Space Force to establish a formal partnership
between the University of Colorado and the Space Force,” Thompson said.
Signing an MOU is only the first step in defining the partnership.
Next, the Space Force will work with CU and each university that
follows to outline specific implementation milestones to meet the
program’s four main goals.
1) Establish opportunities for world-class research, advanced academic
degrees, and workforce and leadership development for USSF Guardians;
2) Identify and pursue research areas of mutual interest with member
universities, individually and collectively; 3) Establish scholarship,
internship and mentorship opportunities for university students and
ROTC cadets; and 4) Recruit and develop diverse officer, enlisted, and
civilian Guardians with a particular focus on Science, Technology,
Engineering, and Mathematics. (8/20)

Unlocking New Economic Frontiers in
Space (Source: Space News)
While some may debate the scientific and societal benefits of space
tourism flights as well as their cost, the symbolic and technical
impact of the past several days cannot be ignored. On the heels of the
2019 commemoration of Apollo 11 and its monumental legacy for crewed
spaceflight, we are now witness to another profound first step for
humankind.
These flights represent the start of a thrilling new space race as well
as a time to celebrate a key milestone of our civilization. After all,
our overall advancement and progress have always been measured by
transportation and exploration. While reflecting that the real
competitors in this arena are the U.S and Chinese governments, NASA
Administrator Bill Nelson remarked that Branson’s flight is a “great”
milestone. (8/21)
Space Tourism’s Environmental Price Tag
(Source: Space News)
Whether or not you agree with Elon Musk that we need higher volume and
lower cost access to space so that a small portion of humanity can flee
our imperiled planet and become planetary refugees, at least he has a
plausible justification (albeit one that deserves scrutiny and debate)
for undertaking major industrial activities and launch operations that
inject thousands of tons of carbon and other greenhouse gasses (GHG)
into the atmosphere.
The backdrop, though, is that we are reeling from multiple and
recurring extreme weather events caused at least in part by climate
change wrought by human activities. So, how do Richard Branson, Jeff
Bezos, and to some extent, Elon Musk, justify their extensive,
carbon-generating activities? Space Tourism!
The carbon footprint and other GHG contributions from the development,
construction and operation of space launch systems is massive. As with
many human activities, we are only beginning to quantify the total
impact of this industry, but it is not impossible to do so; recall the
Total Cost of Ownership (TCO) analyses frequently conducted by
companies to justify their investments. Whatever the specific analysis
eventually reveals, we are talking about tons and tons and tons of
atmospheric carbon. It is truly a massive footprint. I challenge the
launch services providers to demonstrate otherwise. (8/21)
Billionaire Anders Povlsen Fails in UK
Spaceport Legal Challenge (Source: Northern Scot)
A Moray-based company has welcomed the failure of a legal bid to stop
Britain's first spaceport from being built. Orbex, which is based in
Forres Enterprise Park, says today's ruling has opened the way for work
to push ahead at a site in Sutherland. Danish-born billionaire and
environmentalist Anders Povlsen instigated action to stop the plans
back in May at the Scottish Land Court.
Mr Povlsen, who lives near Kingussie, put forward a list of 61
objections which touched on a wide variety of issues including the
site's environmental impact. However, in his legal opinion delivered
today, Lord Doherty rejected them all. The result has been welcomed by
Chris Larmour, who is the CEO of Orbex, the Forres-based company that
is building the rockets which will be launched from the site. (8/20)
Last Stop on the Way to the Cosmos? No
Thanks (Source: New York Times)
On an isolated archipelago off the coast of Georgia, where the vestiges
of America’s Gilded Age aristocracy keep sprawling estates in tropical
wilds, a controversy is roiling over a proposed spaceport. On one side
of the fight are the commissioners of Camden County, Ga., who have put
nine years and close to 10 million taxpayer dollars toward the
construction of a rocket launch facility on the mainland that they say
will bring jobs, tourism and cachet to the area of about 55,000 people.
On the other are residents of the nearby barrier islands and coastline
who fear falling debris, toxic plumes and catastrophic fire. The heirs
to the Coca-Cola fortune have homes on one of these islands, as do
descendants of the Carnegies and other families known for generational
wealth, so it’s easy for the spaceport’s most ardent champions to paint
opposition to it as “elitist.”
But the fears aren’t based on nothing: Last September, one of the same
class of rockets for which Camden County is tailoring its application
tumbled from the sky in flaming pieces, igniting fires on public land
near its launch site on Kodiak Island in Alaska. In 2014, a different
type of rocket, launched from Wallops Island, Va., flew for six seconds
before it fell to the ground and exploded, burning 15 acres and blowing
windows and doors off buildings over a mile away. Click here.

Rocket Lab's High-Stakes Bid to Match
SpaceX's Dominance (Source: Dot.LA)
A Long Beach company that has taken on SpaceX to become one of the
leaders in small satellite launches is set to go public next week.
Rocket Lab will arrive on Wall Street in a deal with a blank-check
company that pegs the 15-year old satellite launcher's value at $4.1
billion. Rocket Lab first announced its plans in March to go public via
a SPAC deal. Shareholders on Friday approved the merger. The company
will trade on the NASDAQ beginning Aug. 25 under the ticker symbols
RKLBW and RKLB.
It couldn't come at a better time, with the market for satellite
launches growing and the company mired in debt. Rocket Lab, which has
raised $400 million in capital, lost $55 million alone last year,
according to filings. That net loss is an increase from 2019, which saw
the company lose about $30.4 million. The company declined to comment
for this article. In an investor presentation filed Aug. 18, Rocket Lab
revealed just how tough it has been to sustain its reusable rocket,
called Electron, and take on SpaceX CEO Elon Musk.
"The Company has suffered recurring losses from operations that raise
substantial doubt about its ability to continue as a going concern,"
auditors noted. The deal is projected to give Rocket Lab some
much-needed funds, nearly $750 million in cash. Vector will contribute
the majority of that money but existing Rocket Lab investors BlackRock
and Neuberger Berman, which are part of the special purpose acquisition
company or SPAC, will also participate. (8/20)
Virgin Galactic Stock-Price Target
Slashed 39% by Bank of America as Analysts Expect Delays in Commercial
Spaceflight Timeline (Source: Business Insider)
Bank of America slashed its Virgin Galactic from $41 to $25 on Friday,
representing a downgrade of 39%. Analysts cited delays in the company's
commercial space flight schedule and a lack of catalysts in the short
term. Virgin Galactic fell about 1% Friday to $23.99. Analysts lowered
their price target to $25 from $41. Shares of Virgin Galactic traded
just above $24 Friday afternoon and are down 4.8% for the week.
BofA said that a longer maintenance for Virgin's Eve Mothership will
delay the company's first commercial passenger flight to late into the
third quarter of 2022 from early 2022. This will result in lower
short-term earnings estimates, said the analysts. In the long term,
analysts also anticipate that Virgin's shot at orbital customer travel
won't come to fruition until 2035. They previously estimated 2028 for
the base case. (8/20)
Top Talent Departs Jeff Bezos’ Blue
Origin as NASA Lander Fight Escalates (Source: CNBC)
Blue Origin has lost more than a dozen key leaders and top engineers
this summer, CNBC has learned, with most leaving in the weeks after
founder Jeff Bezos’ spaceflight. Several of the engineers who left were
part of Blue Origin’s astronaut lunar lander program. Earlier this year
Blue Origin lost its bid for a valuable NASA development contract.
Shortly after Bezos’ spaceflight, Blue Origin gave all its full-time
employees a $10,000, no-strings-attached cash bonus, multiple people
familiar with the situation told CNBC.
Two of the engineers, Nitin Arora and Lauren Lyons, this week announced
jobs at other space companies: Elon Musk’s SpaceX and Firefly
Aerospace, respectively. Others quietly updated their LinkedIn pages
over the past few weeks. Each unannounced departure was confirmed to
CNBC by people familiar with the matter. Those departures include: New
Shepard senior vice president Steve Bennett, chief of mission assurance
Jeff Ashby (who retired), New Glenn senior director Bob Ess, and New
Glenn senior finance manager Bill Scammell.
Also gone are senior manager of production testing Christopher Payne,
New Shepard technical project manager Nate Chapman, senior propulsion
design engineer Dave Sanderson, senior HLS human factors engineer
Rachel Forman, BE-4 lead integration and testing engineer Jack Nelson,
and others. Those who announced they were leaving Blue Origin did not
specify why, but frustration with executive management and a slow,
bureaucratic structure is often cited in employee reviews on job site

Perspectives on UFOs From Across the
Atlantic (Source: Air & Space)
Last week the German Aerospace Society held a workshop to discuss the
search for extraterrestrial intelligent life and whether a recently
released Pentagon report on Unidentified Aerial Phenomena—the new
preferred name for UFOs—should change our outlook in this regard.
Invited speakers were Massimo Teodorani, an astrophysicist and book
author from Italy, Hakan Kayal, a remote sensing expert from the
University of Würzburg in Germany, and myself.
The consensus of the workshop participants was that UAPs should be
investigated with greater openness, and without a stigma. According to
Kayal, the low but significant percentage of observations that remain
unexplained (3.4 percent, according to GEIPAN) could be due to secret
technology developments, previously unknown natural phenomena, or
extraterrestrial intelligence, any of which would be exciting and
important to know about. I’m confident that science will eventually be
successful in providing an answer, especially as sensing technology
improves. (8/16)
