NASA: Spacecraft’s Impact Changed
Asteroid’s Orbit (Source: AP)
An asteroid that NASA used for target practice a few years ago was
nudged into a slightly different route around the sun, findings that
could help divert a future incoming killer space rock, scientists
reported Friday. It’s the first time that a celestial body’s orbit
around the sun was deliberately changed. The asteroid that NASA’s Dart
spacecraft slammed into was never a threat to Earth. (3/6)
Satellite Firm Pauses Imagery After
Revealing Iran’s Attacks on US Bases (Source: Ars Technica)
Planet Labs, one of the world’s leading commercial satellite imaging
companies, said Friday it is placing a hold on releasing imagery of
some parts of the Middle East as a regional war enters its second week.
The company operates a fleet of several hundred Earth-imaging
satellites designed to record views of every landmass on Earth at least
once per day. (3/6)
DARPA Seeks Faster Production of
Hypersonic Heat Shields (Source: Defense Blog)
DARPA has launched a new program aimed at accelerating the production
of heat-resistant structures used in hypersonic weapons. The
initiative, called Carbon Crunch, focuses on developing faster
manufacturing methods for carbon-carbon aeroshells that protect
hypersonic vehicles during flight. The effort is intended to address a
major production challenge facing hypersonic weapon programs. While
several countries are developing missiles capable of traveling at
extreme speeds, manufacturing the specialized materials required to
withstand those conditions remains slow and complex. (3/6)
Amazon Urges FCC to Deny SpaceX Plan
to Launch 1 Million Satellites (Source: PC Mag)
Starlink rival Amazon Leo is calling on the Federal Communications
Commission to shoot down SpaceX’s 1 million-satellite proposal for
orbiting data centers, going as far to claim the project would take
“centuries” to deploy. “In short, the Application seems to describe a
lofty ambition rather than a real plan—and a speculative placeholder
rather than a complete application under the Commission’s rules,”
Amazon Leo said.
On Friday, the Amazon business sent a 17-page filing to the FCC, urging
a denial, when SpaceX CEO Elon Musk wants to use the “up to” 1 million
satellites to create a massive network of orbiting data centers around
the planet. (3/7)

Arrays for Space-Based Data Centers (Source: Insider Monkey)
Rocket Lab introduced advanced silicon solar arrays specifically
designed to power gigawatt-scale space-based data centers. As
terrestrial facilities face increasing constraints regarding land use,
water consumption for cooling, and power availability, the company is
positioning orbit as the next frontier for computing infrastructure.

China Investment is Challenging US to
Become the Next Great Space Power (Source: CNBC)
Chinese investment in its commercial space sector, including from
private and government sources, increased from $340 million in 2015 to
about $3.81 billion in 2025 according to Orbital Gateway Consulting.
Over the last decade, China has spent over $104 billion on civil,
military and commercial space efforts.
“The immediate question you’ll probably ask me is what did the U.S.
spend in the equivalent amount of time? The estimates that we had was
over five times more.” ASU's Jonathan Roll said. “But the real
narrative is that China keeps increasing its expenditures. So they’re
progressing towards their goal of being a leader, if not the leader in
space science.” (3/7)
Humanity Heating Planet Faster Than
Ever Before (Source: The Guardian)
Humanity is heating the planet faster than ever before, a study has
found. Climate breakdown is occurring more rapidly with the heating
rate almost doubling, according to research that excludes the effect of
natural factors behind the latest scorching temperatures. It found
global heating accelerated from a steady rate of less than 0.2C per
decade between 1970 and 2015 to about 0.35C per decade over the past 10
years.
The rate is higher than scientists have seen since they started
systematically taking the Earth’s temperature in 1880. “If the warming
rate of the past 10 years continues, it would lead to a long-term
exceedance of the 1.5C (2.7F) limit of the Paris agreement before
2030,” said Stefan Rahmstorf. The researchers said the acceleration
fell within the scope of climate models. (3/6)
When Will New Glenn Fly Again?
(Source: USA Today)
New Glenn has yet to get off the ground in 2026. Blue Origin had been
working toward a February launch of the rocket, which hasn't lifted off
since its second-ever flight in November. All signs point to liftoff no
earlier than sometime in March from Launch Complex 36 at the Cape
Canaveral Space Force Station in Florida. And this time around, the
rocket is due to help deliver to orbit broadband network satellites for
AST SpaceMobile. (3/5)
