SpaceX Confirms Shift to Starship for Deploying Starlink
Deployment (Source: Space News)
SpaceX says it plans to rely on its new Starship vehicle for deploying
the second generation of its Starlink constellation. SpaceX said in a
filing with the FCC that it no longer proposes to launch the 30,000
satellites of that Starlink Gen2 system using its Falcon 9, which would
have required far more launches than the larger Starship. That
constellation is separate from its first-generation Starlink system
that the company is now deploying, which is authorized for 4,408
satellites. The FCC has not yet approved SpaceX's plans for Starlink
Gen2, but SpaceX asked the FCC to expedite approval now that it has
settled on the use of Starship to launch those satellites.
The proposed Starship configuration, which SpaceX had earlier said was
its preferred option, comprises 29,988 satellites at altitudes of
between 340 and 614 kilometers across nine inclined orbits. The
now-abandoned Falcon 9 configuration would have spread 29,996
satellites across 12 orbital inclinations, at altitudes between 328 and
614 kilometers. Amazon and other SpaceX rivals had called on the FCC to
dismiss the amended plan, saying requesting permission for more than
one configuration encourages speculative application behavior from
future constellation operators.
Editor's Note:
Unless SpaceX intends to launch these Starship missions from Florida
(and even if they do), this could result in a steep drop in Florida's
annual launch rate. (1/11)

Spare Parts Shortage Could Hinder
Increased Launch Cadence at Cape Canaveral and Vandenberg Spaceports
(Source: Space News)
A lack of spare parts for some range equipment could hinder projections
of growing launch activity at two launch sites. A report by the
Pentagon's inspector general found that 28% of range equipment at the
Eastern and Western Ranges lacked spare parts, often because the
equipment was obsolete and the companies that produced them are no
longer in business. A lack of spare parts has not affected launches in
recent years, but the Space Force is projecting a sharp increase in
launches at both ranges in the next five years, driven by commercial
activity.
The Space Force is working on range modernization efforts to address
the concerns in the report, a project called Range of the Future. “It’s
an unfortunate name,” said Col. James Horne, deputy director of launch
and range operations for Space Systems Command at Patrick Space Force
Base, at the Global Spaceport Alliance meeting. “We believe that it’s
the ‘range of the now.’ There’s so many things that we’ve done just to
enable the current surge we’re seeing in launch.” (1/11)
Russian Debris Hits Chinese Satellite
(Source: Space News)
A piece of debris from a Russian launch hit a Chinese satellite last
year. China’s Yunhai-1 (02) satellite, launched in 2019, suffered a
breakup event in March 2021. The U.S. Space Force concluded that
Yunhai-1 (02) collided with a small, mission-related debris object from
a Zenit-2 launch vehicle that launched the Russian Cosmos 2333 military
signals intelligence satellite in 1996. The breakup of Yunhai-1 (02) is
the fifth confirmed accidental collision between two cataloged objects.
Despite the impact, there is evidence that the Chinese satellite is
still operational to some degree. (1/11)
SOFIA's Increased Productivity Cited
to Keep Telescope Alive (Source: Space News)
NASA's SOFIA airborne observatory, targeted for cancelation, is making
its case for continued operations. NASA's fiscal year 2022 budget
proposal called for terminating the program because of its high cost
and low scientific productivity, and the astrophysics decal survey
published in November also recommended shutting down SOFIA. At a town
hall meeting Monday, SOFIA officials said that its scientific
productivity had increased significantly in recent years, with more
time available for observations and an increase in publications based
on data obtained by SOFIA. They argued that SOFIA can address a third
of the scientific priorities of the decadal survey. Congress has yet to
decide on funding SOFIA as it has yet to pass a 2022 spending bill.

Lyten Develops Advanced Battery
Prototype for Small Satellites (Source: Space News)
A battery manufacturer has prototyped an advanced battery design for
small satellites under a contract from the Defense Innovation Unit
(DIU). Lyten was one of 12 companies that submitted bids in response to
a January 2020 solicitation from DIU seeking energy storage and
management solutions to improve the duty cycle of small satellites. The
company received an other transactions authority award that spring to
demonstrate a lithium-sulfur battery capable of three times the energy
storage capacity of current lithium-ion batteries. (1/11)
NASA's Calvin Takes Dual Role

A climate scientist is taking on two roles at NASA. The agency
announced Monday that it selected Katherine Calvin as both the new
chief scientist of the agency and its senior climate adviser. Calvin
had been an Earth scientist at the Pacific Northwest National
Laboratory's Joint Global Change Research Institute, working on models
examining the interactions between human and Earth systems. As chief
scientist, she succeeds Jim Green, who retired from NASA at the
beginning of the month. Gavin Schmidt, who had been acting senior
climate adviser since the agency established the position nearly a year
ago, returns to his role as director of the Goddard Institute for Space
Studies. (1/11)

Starlink's Self-Heating Internet
Satellite Dishes Are Attracting Cats (Source: Gizmodo)
SpaceX’s Starlink has been making steady gains with its fledgling
satellite internet service, surpassing 100,000 terminals shipped in
2021 and showing promising improvements in performance after initial
speed tests produced lackluster results. However, the company’s run
into an unforeseen hiccup with its dishes: Cats love them. “Starlink
works great until the cats find out that the dish gives off a little
heat on cold days,” tweeted Starlink user Aaron Taylor.
His recent image of five cats huddled together on top of a Starlink
dish went viral. In the photo, the Starlink dish is installed at ground
level and surrounded by snow. As noted by the Tesla- and SpaceX-focused
news outlet and store Tesmanian, the dish’s Snow Melt Mode may be to
blame. Launched in 2020, this feature enables dishes to use
self-heating capabilities to prevent snow build-up from interfering
with the signal—and apparently provides a toasty outdoor lounge space
for critters. (1/8)
NASA Has Supported Multiple Autonomous
Flight Termination Systems (Source: SPACErePORT)
Last week's SPACErePORT included an article on NASA's NAFTU system, now
undergoing final certification at the Wallop Island spaceport in
Virginia. NAFTU isn't the only such system in development by NASA. The
AFTS (also known as Autonomous Flight Safety Systems or AFSS by the
military) project began over 20 years ago. Sagrad Inc., based on
Florida's Space Coast, developed an AFTU with support from NASA
technology transfer office in 2016. The Sagrad AFTU is fully qualified
for flight.
While NASA/Wallops has been developing their software for a couple of
years now, and Sagrad developed their AFTU software in 10 months and
has been consulting with the FAA and the Space Force 45th and 30th
Launch Deltas since April 2021. Sagrad's Next Generation AFTU which is
called the Integrated Autonomous Flight Termination Unit (IAFTU) will
be completed and fully qualified by 4th QTR 2022. They also have neen
working with vertical launch companies planning operations at the Cape
Canaveral Spaceport, Vandenberg SFB, and Alaska's Kodiak Island
spaceport. (1/10)
Going to Mars is Stupid
(Source: The Hill)
Going to Mars is stupid. I know, there are hundreds to thousands of
people in the United States and around the world who have financial and
other reasons for pushing spacefaring nations and private enterprises
into sending humans to Mars. To them I will gladly double down and say
that going to Mars is stupider than stupid. Going to, and trying to
exist on, Mars is fraught with unnecessary risk. The logistical and
spacefaring reasons for not attempting the journey are many, each
compelling in its own right. Here are but a few lowlights:
The launch window for Mars opens only every two years. When that window
is open and Mars is in opposition to our sun, the one-way journey still
would take 6 to 10 months. Danger No. 1 is the risk of medical or
mechanical emergencies. The crew would be on their own. A round-trip
journey of up to two years would subject the crew to immense physical
and psychological challenges from living in the tiny confines of their
spacecraft. Solar and cosmic radiation would constantly bombard the
craft. At what point does such risk become unacceptable?
Once the crew reaches Mars, what then? They’ll plant a flag — say, one
from the United Nations — on the surface, look around a little and then
begin the journey home. In essence, it would be a $100 billion+ trip to
plant a flag. Or, let’s say the crew attempts to stay for a few weeks
before heading back to Earth. This would require building a
multibillion-dollar facility with an artificial atmosphere and
protections. But again, to what end? To prove that humans can stay a
few weeks before acknowledging the waste of money? What is the actual
point of going to Mars, other than, perhaps, to prove it can be done?
There is zero benefit to humanity. (1/10)
