All Hail the Ariane 5 Rocket, Which
Doubled the Webb Telescope’s Lifetime (Source: Ars Technica)
There were two stunningly good pieces of news about the James Webb
Space Telescope this weekend. One was widely reported—that after an
intricate, two-week process, the telescope completed its deployment
without any difficulties. The next steps toward science operations are
more conventional. The other piece of news, less well-covered but still
important, emerged during a news conference on Saturday. NASA's Mission
Systems Engineer for the Webb telescope, Mike Menzel, said the agency
had completed its analysis of how much "extra" fuel remained on board
the telescope. Roughly speaking, Menzel said, Webb has enough
propellant on board for 20 years of life.
This is twice the conservative pre-launch estimate for Webb's lifetime
of a decade, and it largely comes down to the performance of the
European Ariane 5 rocket that launched Webb on a precise trajectory on
Christmas Day. Prior to launch, the telescope was fueled with 240
liters of hydrazine fuel and dinitrogen tetroxide oxidizer. Some of
this fuel was needed for course adjustments along the journey to a
stable point in space, about 1.5 million km from Earth, where Webb will
conduct science observations. The remainder will be used at Webb's
final orbit around the stable Lagrange point for station-keeping and to
maintain its orbit. (1/10)
Proliferated Architecture Necessary
for Future Satellite Communications (Source: Air Force Magazine)
When it comes to the Defense Department’s plans for satellite
communications, the Pentagon will need all different kinds of space
architectures, two top Pentagon officials said. David Voss, director of
the Spectrum Warfare Center of Excellence at the Space Warfighting
Analysis Center, and Stephen Forbes, Blackjack program manager at
DARPA, addressed the need for proliferated architectures while
discussing a recent Mitchell Institute policy paper, “The Backbone of
JADC2: Satellite Communications for Information Age Warfare.”
The paper by retired Air Force Gen. Kevin P. Chilton and senior analyst
Lukas Autenreid recommended that the Space Force “distribute,
disaggregate, diversify, and expand its SATCOM options,” particularly
by building out a constellation of low Earth orbit satellites and
linking them with laser communications to create a mesh network. But
that’s not to say that GEO satellites don’t have some value, they
agreed. Analysts and observers have been warming to the idea of
free-space laser communication, or lasercom, due to it being faster and
more secure than radio waves. (1/6)

Yes, There is Really 'Diamond Rain' on
Uranus and Neptune (Source: Space.com)
At first glance, Uranus and Neptune are just bland, boring balls of
uninteresting molecules. But hiding beneath the outer layers of those
worlds, there may be something spectacular: a constant rain of
diamonds. The idea of diamond rain was first proposed before the
Voyager 2 mission which launched in 1977. The reasoning was pretty
simple: We know what Uranus and Neptune are made of, and we know that
stuff gets hotter and denser the deeper into a planet you go.
The mathematical modeling helps fill in the details, like that the
innermost regions of the mantles of these planets likely have
temperatures somewhere around 7,000 kelvins (12,140 degrees Fahrenheit,
or 6,727 degrees Celsius) and pressures 6 million times that of Earth's
atmosphere. Those same models tell us that the outermost layers of the
mantles are somewhat cooler — 2,000 K (3,140 F or 1,727 C — and
somewhat less intensely pressurized (200,000 times Earth's atmospheric
pressure). And so, it's natural to ask: What happens to water, ammonia
and methane at those kinds of temperatures and pressures?
With methane, in particular, the intense pressures can break the
molecule apart, releasing the carbon. The carbon then finds its
brethren, forming long chains. The long chains then squeeze together to
form crystalline patterns like diamonds. The dense diamond formations
then drop through the layers of the mantle until it gets too hot, where
they vaporize and float back up and repeat the cycle — hence the term
"diamond rain." (1/10)
US ISS Extention Puts Partners in
Motion (Source: Space News)
The decision by the U.S. to formally extend operations of the
International Space Station has started the decision-making process
among other station partners. NASA announced at the end of December
that the White House had committed to extending operations of the ISS
from 2024 to 2030, a move immediately endorsed by the European Space
Agency. At a conference last week, representatives of the Canadian
Space Agency and Japan Aerospace Exploration Agency (JAXA) said that
announcement was a "trigger" for them to start their own plans for an
ISS extension. JAXA expects to announce its plans by the end of the
year. Roscosmos has yet to publicly comment on an ISS extension after
its leadership previously raised doubts about doing so. (1/10)
Debris Complicating Perseverance
Sample Collection (Source: NASA)
Engineers are looking into a problem with the latest sample cached by
NASA's Perseverance Mars rover. NASA said Friday that the rover
collected a sample from a rock in late December, but rover operators
noticed an issue when transferring the sample to a "bit carousel" from
the sampling drill. Images showed several pieces of debris the size of
pebbles in the bit carousel, which scientists think are parts of the
rock that fell out of the sample tube. That debris prevented the drill
bit containing the sample from seating completely in the carousel.
Designers of the system anticipated the possibility of such debris and
ways to remove it, but the agency said engineers will "take whatever
time is necessary to ensure these pebbles exit in a controlled and
orderly fashion." (1/10)

SpaceX Preparing for Third Rideshare
Launch with Dozens of Small Satellites (Source: Teslarati)
One week after SpaceX and the world’s first orbital launch of 2022, the
company is a few days out from its second launch of the year – this
time carrying dozens of small satellites for a variety of rideshare
customers. Aside from potentially being the world’s second orbital
launch of the year, the mission – known as Transporter-3 – will be the
third Falcon 9 launch dedicated to SpaceX’s Smallsat Rideshare Program,
which offers what is likely the world’s most affordable ticket to orbit.
Prospective customers buying directly through SpaceX can currently pay
just $1 million to launch up to 200 kg to sun-synchronous low Earth
orbit (LEO). In just two Transporter launches, the company has
delivered almost 220 small satellites to orbit for dozens of different
customers – including startups, universities, space agencies, student
groups, science teams, and more. While rideshare payloads lose out on
the benefits of hands-on, white-glove customer service and a more
direct, tailored orbit insertion offered by a dedicated launch, the
small rockets that offer direct launch services for small satellites
are extremely expensive.
There are only two relatively affordable small rockets that are active
today and have successfully launched at least a few times. Rocket Lab’s
Electron is capable of launching 200 kilograms to a 500 km
sun-synchronous orbit (SSO) for about $7.5 million – $37,500/kg if
fully exploited. While it’s only completed two successful launches,
Virgin Orbit’s air-launched LauncherOne rocket is capable of delivering
300 kg to the same orbit for $12 million ($40,000/kg). Astra’s Rocket
3.0 vehicle will cost at least $2.5 million to launch 150 kg to
SSO – about as good as dedicated small launch affordability is ever
going to get. (1/10)
What Will the US Space Force Be Able
to Do With its New GPS III Variant? (Source: C4ISRnet)
The U.S. Space Force has yet to launch all of the GPS III satellites at
its disposal, but work on new, more powerful versions is already
underway. New GPS III Follow-on satellites — or GPS IIIF for short —
will continue to improve the constellation’s accuracy and protection
against jamming. The Space Force has a contract with Lockheed for up to
22 GPS IIIF satellites. The service already exercised contract options
for seven GPS IIIF satellites.
Most notably, the new space systems will prove a new Regional Military
Protection capability, a steerable M-code signal that can concentrate
the effect in a specified region. RMP can provide up to 60 times
greater anti-jamming measures, helping ensure soldiers can access
critical position, navigation and timing data in contested
environments. Other new features include a laser retroreflector array
to increase accuracy; an upgraded nuclear detection detonation system
payload; and a search and rescue payload.
The company claims its new bus, which will also be used for the Space
Force’s next missile warning satellites, will have greater resiliency
and cyber protections, more power, and better propulsion. And thanks to
a new port on the LM2100 bus, it will be possible to upgrade GPS IIIF
satellites on orbit. The company’s Augmentation System Port Interface
essentially works as a USB port for the satellite, allowing the Space
Force to launch new payloads into space that can be plugged into the
system. (1/9)
SpaceX Simulates Lifting Starship with
Launch Tower ‘Arms’ (Source: Teslarati)
SpaceX has taken Starbase’s rocket-catching launch tower ‘arms’ to new
heights during the latest series of proof tests. That process began in
earnest on January 4th, when SpaceX lifted, opened, and swung the
tower’s building-sized arms for the first time. Four days later, SpaceX
performed a variation on the first round of tests, again slowly lifting
the assembly up the side of the launch tower and opening and closing
the arms.
The most notable difference was the addition of a pair of tandem swing
tests, which hinted at more applied tests that were soon to come. While
subtle, SpaceX also performed some basic tests with a third Starship
fueling arm higher up on the tower, very slowly swinging it towards
where Starship would be standing. On Sunday afternoon, a third major
round of testing kicked off. This set of tests was considerably more
focused than the prior two, suggesting that it was more of a simulation
of the main purpose of the arms.
Instead of lifting a few dozen feet and performing basic actuation and
coordination tests, SpaceX simply lifted the arm assembly up along the
tower’s exterior and didn’t stop. There were a few temporary pauses but
the arms ultimately reached the approximate height they’d need to reach
to stack a Starship on top of a Super Heavy booster. In fact, despite
being (in)famous for being partially designed to catch boosters and
ships out of mid-air, the main purpose of the arms – and likely the
only reason they exist at all – is to safely, accurately, and precisely
lift, install, and stack Starships and Super Heavy boosters. (1/10)
Why Elon Musk's SpaceX Starlink
Satellites Look So Weird (Source: New Zealand Herald)
If you happen to see a peculiar-looking, chain-like object zipping
across the sky at dusk or dawn, it's likely part of Elon Musk's grand
vision of offering fibre-speed internet from above. That's Starlink – a
constellation of more than 1,700 satellites operated by the tech
billionaire's SpaceX, and which deliver internet access to remote spots
as they communicate with ground-based transceivers from low Earth orbit.
The reason they first appear as a chain is because that's really what
they are: stacks of dozens of flat-panel satellites, weighing just over
a quarter of a tonne each. With the help of krypton-fuelled ion
thrusters, the satellites disperse and climb into their operating
orbit, at an altitude of around 550km. University of Auckland
astronomer Professor Richard Easther said the satellites were easily
distinguishable from the International Space Station, which could also
be regularly spotted over New Zealand. "While the ISS essentially
appears as one bright light, the newly-launched Starlink satellites
look like a whole bunch of stars, moving in unison with each other, in
a line across the sky." (1/9)

Now We Know Why Spaceflight Affects
Your Eyes (Source: Universe Today)
70% of astronauts who spend time on the International Space Station
(ISS) experience swelling at the back of their eyes, causing blurriness
and impaired eyesight both in space and when they return to Earth.
Sometimes, it’s permanent. Understanding the way microgravity affects
the eyes, and the human body as a whole is an essential part of
preparations for future long-duration spaceflights to the Moon and
Mars.
In an effort to understand the cause of these eye problems, researchers
at the Medical University of South Carolina used MRI scans of twelve
ISS astronauts to measure the intracranial venous system (veins that
circulate blood to the brain) before and after flight. They’ve
determined that there is a strong connection between the swelling of
these veins and the onset of eye trouble. The effect of spaceflight on
the eyes is known as spaceflight-associated neuro-ocular syndrome
(SANS). SANS is so common that “it’s gotten to the point where
astronauts actually carry extra pairs of glasses when they go into
space. (1/9)
