Supersonic Flight Is Making a Comeback
Decades After the Concorde. But One Big Hurdle Remains (Source:
CNN)
The skies of Oklahoma City roared for six months in 1964 as military
aircraft intentionally rattled the population below with a daily
barrage of thunderous sonic booms. It was a controversial test — the
consequences of which have lingered to this day. The booms — 1,253 in
total — were part of an effort by the FAA to gauge the public’s
attitude toward supersonic flight. A survey of 3,000 Oklahoma City
residents at the end of the 1964 test found that 73% felt they could
live with sonic booms.
However, the program generated immediate lawsuits to stop the flights,
and the FAA received about 12,400 calls from people complaining about
the noise. The agency eventually had to compensate some locals for
damage to windows and walls. The FAA's new proposed rule indicates the
exact threshold of sound pressure at the surface that any aircraft
flying over land in the US would be allowed to produce 0.11 pound per
square foot, which is equal to a moderate thump. By comparison, the
Oklahoma tests produced booms as intense as 1.6 pounds per square foot,
over 14 times more than the FAA’s proposed new limit.
“Manufacturers have demonstrated it is possible to fly supersonic
aircraft without sonic booms reaching the surface by using sonic boom
abatement techniques, making complete prohibition on civil supersonic
flight outside of test areas no longer appropriate," according to the
FAA. (8/7)
Chinese Company Landspace Targets Aug.
10 for Historic Launch and Landing Attempt (Source: Space.com)
The Chinese commercial launch company Landspace is set for a second
attempt at catching an orbital booster. The startup launched its first
Zhuque-3 rocket in December 2025, in what was a milestone for Chinese
rocket reusability efforts. While the Zhuque-3 second stage
successfully reached orbit, the first stage exploded in a dramatic
fireball during its final powered descent toward the landing pad. Now,
Landspace is poised for a second attempt at liftoff and landing. (8/7)
Environmental Groups Challenge FCC
Approval of Startup’s Plan to Beam On-Demand Sunlight From Space
(Source: NBC)
Four environmental organizations filed a petition Thursday asking the
Federal Communications Commission to reverse its approval of a
startup’s plan to beam on-demand sunlight from space to Earth, arguing
the agency ignored the project’s potential impacts on wildlife,
astronomy research and eye safety.
DarkSky International, Environment America, the American Bird
Conservancy and Public Employees for Environmental Responsibility
called on the FCC to overturn a decision last month authorizing Reflect
Orbital to launch its Earendil-1 demonstration satellite, which will
carry a 59-foot-wide mirror to reflect sunlight onto a specific spot on
the planet during periods of darkness. (8/6)
Cursor Says SpaceX Deal Could be Done
by End of Next Week (Source: Seeking Alpha)
SpaceX could finish its $60 billion acquisition of Cursor as soon as
the end of next week. The Cursor brand name will likely be phased out
for new products in the coming months, according to a report from The
Information on Friday, which cited people familiar with the matter.
Cursor's upcoming general-purpose agent could be branded as Grok Bot.

SpaceXAI Sues Contractor for Unpaid
Data Center Work (Source: ABC24)
SpaceXAI is suing the contractor that claims that SpaceXAI owes nearly
$570 million for unpaid labor performed at its Memphis and DeSoto
County facilities. Tuesday, SpaceXAI filed a federal lawsuit against
Darana Hybrid, Inc. Darana Hybrid, based in Ohio, has filed several
liens claiming that SpaceXAI owes millions for work done at Colossus I
and Colossus II in Memphis and several facilities in DeSoto County,
including its power plant on Stanton Road.
Darana Hybrid claims that SpaceXAI owes a total of $569,348,213.76. In
its complaint, SpaceXAI alleges that Darana Hybrid overbilled by
hundreds of millions of dollars while "selling out their own suppliers
and subcontractors along the way." (8/7)
Pentagon Releases New Batch of UFO
Files (Source: CBS)
The Pentagon on Friday released a new batch of documents and images
related to UFOs, also known as unidentified anomalous phenomena or UAP,
including a military pilot's recollection of a huge, strange triangle
that blocked out the stars over Afghanistan in 2002. The 41 new files,
posted on the Pentagon's UFO website, include a mix of documents,
images and videos. The records come from the Pentagon, FBI, CIA, State
Department and Executive Office of the President, with the oldest being
from 1950 and the most recent being from this year.
Six of the videos show different versions of the same incident — an
encounter over the Gulf of Oman by Special Operations forces on an
AC-130J gunship in September 2021. The report said the forces onboard a
C130 gunship "observed approximately 25 instances of UAPs while
conducting a live fire exercise in the Gulf of Oman... The UAPs were
observed as cold orbs flying at lower altitudes between 250 to 1300 MPH
in different formations as well as maneuvering aggressively. UAPs also
appeared to react to the aircraft firing its main cannon," the report
said. (8/7)
NASA Funds Research into Advanced
Solar Sails (Source: Douglas Messier)
Artur Davoyan of UCLA received a NASA Innovative Advanced Projects
(NIAC) award worth up to up to $175,000 to conduct a nine-month
investigation. NIAC projects are focused on early-stage concept
development and are not considered official NASA missions. "Our concept
integrates two core technologies: (i) A lightweight, coilable truss
structure that deploys a stack of sail membranes, each with an area
between 50–150 m² (limited by the rocket fairing), and (ii) Tensegrity
engineering to maintain the structural integrity and shape of the
deployed system,” the project summary said. (8/8)
Once-Abandoned Spanish Village Becomes
NASA's Eclipse Hotspot (Source: EuroNews)
A tiny village in the province of Burgos, brought back from the brink
of extinction, is about to have its moment in the "shadow" — NASA has
picked Villalibado as one of its ringside seats for the total solar
eclipse on 12 August. Villalibado will now host one of the US space
agency's broadcast teams as the Moon takes center stage. The feed will
beam out worldwide via NASA's digital platforms and San Francisco's
Exploratorium, giving Villalibado more screen time than most villages
get in several centuries. (8/7)
EU Lays Out $18B Satellite
Constellation Plan, with Spanish Firm Winning Key Role (Source:
Breaking Defense)
European officials have agreed to a rollout plan for the continent’s
flagship satellite constellation, adding 66 low Earth orbit (LEO)
satellites to the hundreds already envisioned and naming a Spanish firm
as prime contractor for ground-based communications and networking.
Altogether, the plan for the European Union’s (EU) answer to SpaceX’s
Starlink broadband communications network, called Infrastructure for
Resilience, Interconnectivity and Security by Satellite (IRIS2), is
valued in excess of €15.6 billion ($18 billion).
The first satellite launches are slated for 2029, according to
HispaSat, part of Spain’s Indra Group, which said it had been selected
as the prime contractor for the ground portion of the effort. (8/7)
Rocket Lab Unveils Game-Changing
Flatellites (Source: Motley Fool)
Rocket Lab introduced Flatellites last February, but it hasn't produced
any of those next-gen satellites yet. But it's been acquiring smaller
companies and developing its own components to support the expansion of
that vertically integrated satellite manufacturing business. Rocket Lab
believes that approach will enable it to produce high volumes of
Flatellites "without compromising performance or reliability". It also
expects more of its customers to use Flatellites to rapidly deploy
their own low Earth orbit (LEO) satellite constellations. (8/8)
Alan Shepard's Lunar Golf Shot (Source:

Apollo 14 commander Alan Shepard paused near the end of the mission's
second moonwalk on February 6, 1971 and attached a Wilson six-iron club
head to the handle of a lunar sample collection tool. It was hidden
inside his spacesuit until that moment, and the improvised club had
been approved by NASA but kept secret from television viewers. Shepard
dropped a golf ball onto the Moon's surface and swung one-handed
because his bulky spacesuit made a normal golf swing impossible. The
first shot barely traveled after landing in a nearby crater, but the
second flew much farther. (8/9)
Reduced Gravity Pushes People Toward
Simpler Movement Patterns, Experiments Suggest (Source: Phys.org)
From reaching for a cup of coffee to tying your shoelaces, gravity
shapes nearly all human movement. So how do our bodies react when that
familiar force begins to change? Texas A&M University researchers
are exploring the answer through a multiphase project supported by
NASA. Their latest work examines how the body performs in
altered-gravity conditions to identify challenges astronauts encounter
in space and how the human body adapts when environments change. (8/8)
