SpaceX Vindicates "Dumb" Approach to
Rocket Reuse (Source: Ars Technica)
Many people in the industry were skeptical about SpaceX's approach to
reuse. In the mid-2010s, both the European and Japanese space agencies
were looking to develop their next generation of rockets. In both
cases, Europe with the Ariane 6 and Japan with the H3, the space
agencies opted for traditional, expendable rockets instead of pushing
toward reuse. As a result, both of these competitors for commercial
satellite launches are now about a decade behind SpaceX in terms of
launch technology.
ULA's reaction to SpaceX's plan to reuse first stages a decade ago was
dismissive. The company's engineers wrote papers and performed studies
that argued SpaceX's plans were impractical compared to their
engines-only recovery. ULA dubbed this approach SMART, an acronym for
Sensible Modular Autonomous Return Technology. The implication in this
name, of course, is that SpaceX's booster flyback approach was dumb.
According to the ULA analysis in 2015, the SMART plan would result in
cost savings as soon as the second launch of a booster. SpaceX's
approach, by contrast, would require 10 flights for there to be any
cost savings. One imagines that those engineers never dreamed that, a
decade later, SpaceX would fly the same rocket 30 times and reach an
annual launch cadence that approaches the total number of rockets
United Launch Alliance has flown during its 20-year existence. As for
SMART, it remains a theoretical concept. (8/28)

EchoStar Drops Constellation Plan,
Will Sell Spectrum to SpaceX (Source: Space News)
EchoStar is dropping plans to develop its own direct-to-device
constellation and is selling spectrum to SpaceX. EchoStar announced
Monday that it would sell S-band spectrum to SpaceX for $17 billion in
cash and stock, with SpaceX making $2 billion in EchoStar debt interest
payments through late 2027.
Customers of EchoStar’s Boost Mobile wireless service will get access
to Starlink direct-to-cell capabilities as part of the deal. EchoStar
had planned to use that spectrum for its own direct-to-device satellite
constellation, awarding MDA Space a contract just over a month ago to
build 100 satellites. MDA Space said in a separate statement Monday
that it received a notice from EchoStar terminating that contract. (9/8)
NASA Advances $1.5 Billion Plan for
Commercial Space Station (Source: Space News)
NASA has released more details on how it plans to spend up to $1.5
billion on the next phase of commercial space station development. The
agency released Friday a draft solicitation for the Commercial
Destinations – Development and Demonstration Objectives, or C3DO,
effort, where it will award multiple Space Act Agreements to support
work on commercial stations intended to succeed the International Space
Station.
That would include a four-person crewed mission to such stations for
one month by 2030. The document states that NASA anticipates providing
$1 billion to $1.5 billion from 2026 to 2031 for the C3DO agreements.
NASA announced a little more than a month ago that it was changing
direction on commercial station development, moving away from earlier
plans to award contracts that would lead to permanently crewed
commercial stations. (9/8)
Anduril and Blue Origin to Study
Rocket Cargo for AFRL (Source: Space News)
Anduril Industries and Blue Origin won small study contracts for
“rocket cargo” services. The Air Force Research Laboratory (AFRL) last
month awarded Blue Origin $1.3 million and Anduril $1 million under the
Rocket Experimentation for Global Agile Logistics program, known as
REGAL. Blue Origin will assess how its space vehicles could be adapted
for point-to-point transport of cargo, while Anduril will examine how
to integrate multiple government payloads into a single rocket cargo
delivery system. Several other companies have won similar contracts to
study rocket cargo services, but cost, safety and infrastructure
challenges have kept the concept experimental. (9/8)
Lynk Accelerates Direct-to-Device
(Source: Space News)
Lynk Global says leveraging SES satellites will allow it to accelerate
plans for a global rollout of its direct-to-device services. Lynk CEO
Ramu Potarazu said in a recent interview that the company expects to
achieve global, continuous services in 2027 by augmenting its small
constellation of LEO satellites with satellites in medium and
geostationary orbits owned by SES. Potarazu, a former SES executive,
said working with SES also helps with regulatory issues. Lynk recently
abandoned plans to go public through a SPAC merger, and Potarazu said
the company had enough money to operate for the next two years as it
lines up a new round of funding. (9/8)
GHGSat to Monitor Methane for
ExxonMobil (Source: Space News)
GHGSat announced a deal with ExxonMobil to monitor methane emissions.
The companies said Friday that ExxonMobil will use GHGSat satellites to
track and mitigate methane emissions at its onshore facilities in North
America and Asia. ExxonMobil has now made “a significant investment” in
GHGSat’s emissions monitoring, the companies announced, but did not
disclose the size of the deal. GHGSat has 13 spacecraft in orbit that
monitor millions of industrial facilities worldwide. (9/8)
Orbital Sidekick Reveals Iran Nuclear
Facility Air Strike Damage (Source: Space News)
Orbital Sidekick hyperspectral sensors revealed new information on
damage sustained by Iran’s Fordow nuclear fuel enrichment plant after a
June air strike. The company said its Global Hyperspectral Observation
Satellite (GHOSt) constellation exposed the outline of a rectangular
subsurface structure at Fordow that indicated the “potential collapse
or damage” of an underground facility. That damage was not seen in
conventional optical imagery of the site, the company said. (9/8)
NOAA Orders Radio Occultation Weather
Data From PlanetiQ and Spire (Source: NOAA)
NOAA has ordered more radio occultation weather data from two
companies. The agency said last week it awarded PlanetiQ more than
$24.3 million and Spire nearly $11.2 million to provide
radio-occultation atmospheric profiles using their satellites. Those
profiles, made by monitoring signals from navigation satellites as they
pass through the atmosphere, provide information on atmospheric
conditions used in weather forecasting models. (9/8)
