Galaxy S23 Ultra’s 8K 30fps and 4K 60fps video samples leak
Although we are a week away from the official Galaxy S23 unveiling, almost all the details regarding the entire lineup have been leaked. Now, the first video recording samples from the Galaxy S23 Ultra have been leaked, showcasing its camera prowess.
Edwards Urbina has been posting camera samples from the Galaxy S23 Ultra for the past few days and has now published the first video recording samples from the high-end smartphone. The first video shows an 8K 30fps video captured from the phone’s 200MP rear-facing camera. The second tweet below reveals a 4K 60fps video captured from the same sensor (ISOCELL HP2).
Although Twitter has reduced the quality of the videos through its compression algorithm, we can still notice that 8K video seems a lot smoother compared to 8K 24fps videos from the Galaxy S22 Ultra. Moreover, the dynamic range and audio quality also seem pretty good. Even the 4K 60fps video seems decent in terms of dynamic range and colors.
Still, it is best not to get too ahead of ourselves and wait for the phone to release. Once Samsung launches the device, we will get our hands on it and talk about its camera performance after reviewing the Galaxy S23 Ultra and other devices in the lineup. If you’re thinking of upgrading your phone, you can pre-reserve the Galaxy S23 now and get up to $100 in-store credit.

NASA’s Mars Perseverance rover snags 1st dirt samples
NASA’s most advanced robotic geologist to date has collected its first samples of broken rocks and dust from the Red Planet’s surface.
The Perseverance rover drilled free two of what scientists call regolith samples as it continues its mission to investigate geological processes and to search for tell-tale evidence that life once existed on Mars. The NASA-operated rover grabbed the regolith samples on Dec. 2 and Tuesday (Dec. 6), adding them to its collection of 15 rock cores liberated from the planet’s Jezero Crater (plus one atmospheric sample) since the spacecraft landed in February 2021.
The two new samples differ from Perserverance’s existing rock collection, which were drilled from boulders; the regolith samples come from a mound of wind-blown sand and dust resembling a dune here on Earth, albeit smaller in size.

Although the majority of the samples Perseverance collects throughout its mission will be rock cores that could contain the telltale signs of life, scientists have determined that regolith samples like these could be key to understanding the geological processes that have shaped Mars.
Additionally, regolith samples could help scientists plan for future space missions and mitigate the challenges astronauts could eventually face on the Martian surface.
This is because regolith can affect a wide variety of equipment, from energy-gathering solar panels to the spacesuits worn by astronauts. Not only could fine rock powder and dust jam sensitive parts and even slow down rovers on the surface, but larger pieces of sharp rock within regolith could put astronauts at risk by tearing holes in spacesuits.
“If we have a more permanent presence on Mars, we need to know how the dust and regolith will interact with our spacecraft and habitats,” Erin Gibbons, a doctoral student at McGill University in Canada and a Perseverance team member, said in a statement. “Some of those dust grains could be as fine as cigarette smoke, and could get into an astronaut’s breathing apparatus. We want a fuller picture of which materials would be harmful to our explorers, whether they’re human or robotic.”
However, it’s also possible that Martian regolith could actually be an important resource for crewed space missions to Mars that target longer stays and sustainability in space, since the fine material could be packed against habitats to help shield humans against the harsh solar radiation that streams down to the surface of Mars, which isn’t protected by a magnetic field like Earth’s.
Before anyone gets too excited about this approach, however, scientists need to know whether Martian regolith contains perchlorate, a toxic chemical that could be a health risk to astronauts if ingested or inhaled in large amounts.
Hence the interest in Martian regolith and the effort to include the material in the collection Perseverance is building for the proposed Martian sample return mission being developed by NASA and the European Space Agency to bring the rover’s collection to Earth. Here, scientists could study the regolith in greater detail in labs with more sensitive and powerful equipment than the chemical analysis instruments robots can carry to the Red Planet.
Perseverance collected the samples of regolith using a drill placed on the end of its robotic arm, as it does for rock cores, but employing a different drill bit than the one that it has used for previous samples.
The regolith drill bit resembles a spike with small holes punctuating one end that enables the drill to gather loose material.
This drill bit was engineered and tested using simulated Martian regolith developed by scientists at NASA’s Jet Propulsion Laboratory (JPL) in California. This faux-Mars material consists of volcanic rock crushed into different particle sizes, ranging from large coarse pebbles to fine dust, and was inspired by images of actual Martian regolith and data collected by previous Mars missions.

Bringing Mars Rock Samples Back to Earth – NASA Mars Exploration
November 17, 2022
NASA and the European Space Agency are developing plans for one of the most ambitious campaigns ever attempted in space: bringing the first samples of Mars material safely back to Earth for detailed study. The diverse set of scientifically curated samples now being collected by NASA’s Mars Perseverance rover could help scientists answer the question of whether ancient life ever arose on the Red Planet.
Bringing samples of Mars to Earth for future study would happen in several steps with multiple spacecraft, and in some ways, in a synchronized manner. This short animation features key moments of the Mars Sample Return campaign: from landing on Mars and securing the sample tubes to launching them off the surface and ferrying them back to Earth.
Animation is contributed by NASA’s Jet Propulsion Laboratory, the European Space Agency, Goddard Space Flight Center, and Marshall Space Flight Center.

China moon mission samples upend theories of lunar volcanism
An analysis of lunar samples returned by China’s Chang’e 5 moon mission has produced a new possible answer for volcanism late in the moon’s history.
Lunar samples returned by the Apollo and Luna missions are all older than about 3 billion years, but samples returned by Chang’e 5 in late 2020 confirmed remote sensing analysis that rocks in the area were relatively young, at only 2 billion years old.
Scientists previously speculated that either a relatively high water content or the presence of radioactive, heat-producing elements in the lunar interior might have driven volcanism in a late stage of the moon’s life in some areas, but new Chang’e-5 data published in Nature appears to have ruled out these hypotheses.
Related: China’s fresh moon rocks are younger than the Apollo samples and no one knows why
Researchers led by Chen Yi from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IGGCAS) found that a lower melting point for portions of the lunar mantle could be due to the presence of fusible, easily melted components, leading to young lunar volcanism.
“Recent melting of the lunar mantle can be achieved by either raising the temperature or lowering the melting point. To better understand this problem, we should estimate the temperature and pressure in which the young volcanism was created,” Chen said in a statement (opens in new tab).
The researchers conducted a series of fractional crystallization and lunar mantle melting simulations to compare 27 samples of Chang’e 5 basalt clasts with Apollo basalts. They found that the young magma collected by Chang’e 5 had higher calcium oxide and titanium dioxide contents than older Apollo magmas. These are calcium-titanium-rich late-stage lunar magma ocean cumulates are more easily melted than early cumulates.
“This is a fascinating result, indicating a significant contribution of late-stage lunar magma ocean cumulates to the Chang’e 5 volcanic formation,” said Dr. Su Bin, first author of the study.
The research presents evidence for the first viable mechanism to account for young volcanism on the Moon that is compatible with the newly returned Chang’e 5 samples and could help understanding of the Moon’s thermal and magmatic evolution.
The study was published in the journal Science Advances (opens in new tab) on Friday (Oct. 21).

Here are Pixel 7 Pro Super Res Zoom camera samples [Gallery]
“Next-generation” Super Res Zoom on the Pixel 7 Pro pushes the 48-megapixel telephoto camera to DSLR-level heights, and Google has shared three sets of samples outside of the keynote.
The main Manhattan sample of One World Trade Center starts 0.5x with the second picture below at 1x. It goes all the way to 30x where you can see the fine detail of the antenna spire. Starting at 20x, the Pixel 7 Pro uses a new machine learning upscaler that’s powered by the Tensor G2. Before that, 15x and up uses Zoom Stabilization so that you can “take handheld photos without a tripod.”
These camera samples, and two other example sets, are from Google’s Alexander Schiffhauer, who presented and detailed the Pixel 7 Pro’s zoom upgrades at the Made by Google keynote:
/q
These are some of the last frontiers of smartphone photography, where phones haven’t been able to truly replicate the quality of a DSLR.
In choosing what camera features to work on, Pixel Camera product manager lead said in Google’s new podcast that it looks at why people are “willing to lug around a 15-pound camera, $10,000 dedicated camera” and work on bringing that functionality to smartphones. Google Research has been involved in Super Res Zoom since 2018 with the feature being a combination of hardware, software, and machine learning.
We also have the Golden Gate Bridge in San Francisco and Mendocino, which is also in California. Google’s keynote examples focused on being able to see people from far away.

Mars Perseverance rover collects organic-rich samples in Jezero Crater
NEWYou can now listen to Fox News articles!
NASA said its Mars Perseverance rover has collected rock-core samples in an area long considered by scientists to be a top candidate for finding signs of ancient microbial life.
In an update, the team said its latest findings provide greater detail of the region, with the rover taking four samples from an ancient river delta in the 28-mile-wide Jezero Crater since July.
In total, the rover has collected 12 compelling rock samples.
The crater’s delta formed about 3.5 billion years ago at the convergence of a Martian river and a lake.

The delta’s sedimentary rocks formed when particles of various sizes settled in the environment.
During its first scientific campaign, the rover explored the crater’s floor, finding igneous rock.
“We picked the Jezero Crater for Perseverance to explore because we thought it had the best chance of providing scientifically excellent samples – and now we know we sent the rover to the right location,” Thomas Zurbuchen, NASA’s associate administrator for science in Washington, said in a statement. “These first two science campaigns have yielded an amazing diversity of samples to bring back to Earth by the Mars Sample Return campaign.”
“The delta, with its diverse sedimentary rocks, contrasts beautifully with the igneous rocks – formed from crystallization of magma – discovered on the crater floor,” Perseverance project scientist Ken Farley said. “This juxtaposition provides us with a rich understanding of the geologic history after the crater formed and a diverse sample suite. For example, we found a sandstone that carries grains and rock fragments created far from Jezero Crater – and a mudstone that includes intriguing organic compounds.”
NASA FUNDED TECH THAT HELPS RELIEVE MENOPAUSE SYMPTOMS
One of those rocks is “Wildcat Ridge,” which likely formed billions of years ago.
Perseverance has abraded some surface of the rock so it could analyze the area with its Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals (SHERLOC) instrument.
NASA said the SHERLOC samples were found to feature a class of organic molecules that are spatially correlated with those of sulfate minerals.
The presence of organic molecules, which can contain elements like sulfur, is considered to be a potential biosignature.
While Perseverance and the Curiosity Mars rovers have found evidence or organics before, this detection was made in an area where sediment and salts were deposited into a lake under conditions in which life could have potentially existed.

“In the distant past, the sand, mud and salts that now make up the Wildcat Ridge sample were deposited under conditions where life could potentially have thrived,” Farley explained. “The fact the organic matter was found in such a sedimentary rock – known for preserving fossils of ancient life here on Earth – is important. However, as capable as our instruments aboard Perseverance are, further conclusions regarding what is contained in the Wildcat Ridge sample will have to wait until it’s returned to Earth for in-depth study as part of the agency’s Mars Sample Return campaign.”
