U.S. Officials say Pentagon Committed
to Understanding UFO Origins (Source: Reuters)
Two senior U.S. defense intelligence officials said on Tuesday the
Pentagon is committed to determining the origins of what it calls
"unidentified aerial phenomena" - commonly termed UFOs - but
acknowledged many remain beyond the government's ability to explain.
The two officials, Ronald Moultrie and Scott Bray, appeared before a
House of Representatives intelligence subcommittee for the first public
U.S. congressional hearing on the subject in a half century.
It came 11 months after a government report documented more than 140
cases of unidentified aerial phenomena, or UAPs, that U.S. military
pilots had observed since 2004. The 2021 report included some UAPs
revealed in previously released Pentagon video of enigmatic objects
exhibiting speed and maneuverability exceeding known aviation
technology and lacking any visible means of propulsion or
flight-control surfaces. Bray said those incidents, including one
described by Navy pilots as resembling flying Tic Tac breath mints, are
among cases still categorized as "unresolved." (5/17)

Rocket Engine Exhaust Pollution
Extends High Into Earth's Atmosphere (Source: Space Daily)
Reusable space technology has led to a rise in space transportation at
a lower cost, as popularized by commercial spaceflights of companies
like SpaceX and Virgin Galactic. What is poorly understood, however, is
rockets' propulsion emissions creating significant heating and
compositional changes in the atmosphere. Now researchers have assessed
the potential impact of a rocket launch on atmospheric pollution by
investigating the heat and mass transfer and rapid mixing of the
combustion byproducts for altitudes up to 67 kilometers into the
atmosphere.
"We show that pollution from rockets should not be underestimated as
frequent future rocket launches could have a significant cumulative
effect on the Earth's climate," said co-author Ioannis Kokkinakis. The
researchers found the production of thermal nitrogen oxides (NOx),
components of the combustion exhaust, can remain high up to altitudes
with an ambient atmospheric pressure above or even slightly below the
nozzles' exit pressure, i.e., below an altitude of approximately 10 km.
At the same time, the emitted mass of carbon dioxide as the rocket
climbs 1 kilometer in altitude in the mesosphere is equivalent to that
contained in 26 cubic kilometers of atmospheric air at the same
altitude. (5/18)

The Pentagon's Space Development Agency (SDA) and its contractors have
scrambled to deal with supply chain problems that have affected the
entire space industry. SDA plans to launch 28 satellites between
September and next March, but those spacecraft have been affected by
shortages of microprocessors, focal plane arrays and lower-end items.
SDA Director Derek Tournear said industry competitors agreed to share
parts to help the agency meet that schedule. He warned similar supply

Coast Guard Concludes Investigation
Into Royal Caribbean Ship's Interference with SpaceX Launch
(Source: Orlando Sentinel)
One of the world’s largest cruise ship ran afoul of SpaceX earlier this
year when Royal Caribbean’s Harmony of the Seas wandered into waters it
was supposed to avoid because of a launch attempt. The incident on Jan.
30 caused a scrub of the SpaceX Falcon 9 trying to launch from Cape
Canaveral Space Force Station as the vessel had previously left from
Port Canaveral like it normally would on a Sunday departure.
Leading up to the attempted launch, SpaceX commentators said the Coast
Guard was trying to get word to the ship that it had ventured into the
down-range safety zone off the coast of Brevard County, but the ship
was not able to vacate the zone in time. Mission managers shouting
“Hold! Hold ! Hold!” scrubbed the launch with less than a minute before
the planned liftoff. It was able to launch the following day without
issue sending the COSMO-SkyMed Second Generation FM2 satellite run by
the Italian Space Agency into orbit.
Now more than three months later, the Coast Guard has concluded its
investigation of the incident, as it’s the entity establishing and
enforcing the safety zones. “When these zones are violated, the Coast
Guard may pursue administrative enforcement actions,” reads a statement
from the U.S. Coast Guard 7th District Southeast. “Such actions may
include monetary fines and or future vessel control actions.” The Coast
Guard did not elaborate what sort of action was taken if any against
Royal Caribbean. (5/17)

NASA Concerns Over SpaceX’s KSC
Starship Launch Pad Too Close to Commercial Crew and Falcon Heavy Pad

David West, a member of the Aerospace Safety Advisory Panel, said
SpaceX plans to eventually launch the huge next-generation Starship
rocket, currently under development in South Texas, from the Kennedy
Space Center could pose a risk to the Falcon 9 and Dragon launch
facility at pad 39A. “There are obvious safety concerns about launching
the large, and as yet unproven, Starship in such close proximity,
reportedly only 300 yards or so, from another pad, let alone the path
so vitally necessary for the commercial crew program.”
Pad 39A is also the only launch facility currently capable of launching
SpaceX’s Falcon Heavy rocket, necessary to haul some heavier NASA and
U.S. military spacecraft into orbit. SpaceX is finishing work on a
Starship launch pad in South Texas, but the FAA is reviewing the

Question of Space National Guard Heats
Up Following Legislation, Hearings (Source: Breaking Defense)
With new legislation introduced to force the creation of a Space
National Guard program, the question of the newest military service’s
structure is once again in the spotlight. On May 3, Gen. Jay Raymond,
the Space Force head, told a Senate Armed Services Committee hearing
that a Space Guard setup could be done two ways: “Either have a
separate Space National Guard or take the capabilities from the Guard
and move them into” a single component concept.
Speaking May 13 in front of the House Appropriations defense
subcommittee, Raymond elaborated, saying that working out the service
structure is a top priority for him. The issue has been simmering ever
since the creation of the Space Force in December 2019, with National
Guard leadership vocally making the case for a new branch. Indeed, in
early 2020 top Guard adjutants general broke with the Pentagon to speak
out in favor of a separate Space Guard, and began a congressional
lobbying campaign.
“Without a National Guard component for Space Force, we risk losing
many talented individuals who want to keep serving their country and
their states after they leave active duty, and that is simply
unacceptable,” Feinstein said in the announcement of the legislation.
“Creating a Space Force National Guard would also save money and ensure
a smoother process in the event we need to activate personnel. Not
establishing a Space National Guard was a mistake when Space Force was
created, and this bill will remedy that.” (5/13)
Riding Along For An L-1011 Pegasus Air
Launch Flight Demonstration (Source: Aviation Week)
For the demo mission, Don Walter, chief pilot of L-1011 flight
operations, devised a flightpath that approximated a typical launch
profile. For airspace and time reasons, the route took us over
California’s Central Valley toward Bakersfield rather than into the
Stargazer’s more regular haunts in the Pacific test ranges off the
coast from Vandenberg Space Force Base.
Our approach to the launch point was at roughly half the speed and
one-third the altitude of a standard mission. Walter’s navigation
waypoints were therefore spaced out to replicate the final 12 min. of
the sequence in terms of time rather than distance and brought us to
the initial point (IP) after approaching downwind from the south and
reversing course for the launch.
A typical box could measure 10 X 40 mi., Walter said, and provides a
small margin for launch delay in the event of a last-minute detection
of a potential orbital conflict with a crewed or active spacecraft.
“We’re doing 8 mi. a minute, so we can go for 4 min. and the launch
director can delay the launch—usually by 30 sec. or so—within that
period,” he said. (5/4)
