Antarctica is shrouded in mystery, holding secrets from the past and serving as the site of ongoing covert operations. It's no surprise that numerous restricted zones exist to conceal the truth about what’s really happening there. The intrigue extends beyond the surface, hidden dangers lurk beneath the ice, particularly in the depths of Lake Vostok.
This hidden subglacial lake, sealed off from the world for 15 million years, holds secrets beyond imagination. Preserved in isolation, its ecosystem is unlike anything else on Earth.
When a Russian team drilled into Lake Vostok, they uncovered more than just ancient water. But something went wrong. Two scientists died under mysterious circumstances, and official reports contradict witness accounts. Military operations, classified research, and blurred satellite images suggest something is being hidden.
What are they trying to hide at the bottom of the world? Rumors speak of monstrous, spider-like entities, shape-shifting predators, and colossal, whale-like humanoids known as the "Ningen" a name that means "human" in Japanese.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A scientific balloon is inflated during NASA’s 2023 Antarctic campaign in McMurdo, Antarctica. NASA/Scott Battaion NASA’s Scientific Balloon Program has returned to Antarctica’s icy expanse to kick off the annual Antarctic Long-Duration Balloon Campaign, where two balloon flights will carry a total of nine missions to near space. Launch operations will begin mid-December from the agency’s Long Duration Balloon camp located near the U.S. National Science Foundation’s McMurdo Station on the Ross Ice Shelf.
“Antarctica is our cornerstone location for long-duration balloon missions, and we always look forward to heading back to ‘the ice,’” said Andrew Hamilton, acting chief of NASA’s Balloon Program Office at the agency’s Wallops Flight Facility in Virginia. “It’s a tremendous effort to stage a campaign like this in such a remote location, and we are grateful for the support provided to us by the U.S. National Science Foundation, New Zealand, and the U.S. Air Force.”
This year’s Antarctic campaign includes investigations in astrophysics, space biology, heliospheric research, and upper atmospheric research, along with technology demonstrations. The campaign’s two primary missions include:
GAPS (General Anti-Particle Spectrometer), led by Columbia University in New York, is an experiment to detect anti-matter particles produced by dark matter interactions. The anti-particles stemming from these interactions in our galaxy can only be observed from a suborbital platform or in space, since Earth’s atmosphere shields us from the cosmic radiation. GAPS aims to provide an unprecedented level of sensitivity to certain classes of anti-particles, allowing the exploration of a currently unexplored energy regime of the elusive dark matter. Salter Test Flight Universal, led by NASA’s Columbia Scientific Balloon Facility in Palestine, Texas, will test and validate long-duration balloon and subsystems, while supporting several piggyback missions on the flight. Piggyback missions, or smaller payloads, riding along with the Salter Test Flight Universal mission include:
MARSBOx (Microbes in Atmosphere for Radiation, Survival, and Biological Outcomes Experiments), led by the U.S. Naval Research Laboratory, will expose melanized fungus, called Aspergillus niger, to the stratosphere’s extreme radiation and temperature fluctuations, low atmospheric pressure, and absence of water — conditions much like the surface of Mars. Knowledge of how this fungus adapts to protect itself in this harsh environment could lead to the development of treatments to protect astronauts from high radiation exposure. EMIDSS-6 (Experimental Module for Iterative Design of Satellite Subsystems 6), led by National Polytechnical Institute − Mexico, is a technological platform with experimental design and operational validation of instrumentation that will collect and store data from the stratospheric environment to contribute to the study of climate change. SPARROW-6 (Sensor Package for Attitude, Rotation, and Relative Observable Winds – 6), led by NASA’s Balloon Program Office at NASA Wallops, will demonstrate relative wind measurements using an ultrasonic anemometer designed for the balloon float environment. WALRUSS (Wallops Atmospheric Light Radiation and Ultraviolet Spectrum Sensor), led by the Balloon Program Office at NASA Wallops, is a technology demonstration of a sensor package capable of measuring the total ultraviolet wavelength spectrum and ozone concentration. INDIGO (INterim Dynamics Instrumentation for Gondolas), led by the Balloon Program Office at NASA Wallops, is a data recorder meant to measure the shock, rotation, and attitude of the gondola during the launch, float, and landing phases of flight. Data will be used to improve understanding of the dynamics of flight and to inform the design of future components and hardware. The remaining two piggyback missions are led by finalists of NASA’s FLOATing DRAGON (Formulate, Lift, Observe, And Testing; Data Recovery And Guided On-board Node) Balloon Challenge, sponsored by the Balloon Program Office at NASA Wallops and managed by the National Institute of Aerospace. The challenge was created for student teams to design, build, and fly an autonomous aerial vehicle, deployed from a gondola during a high-altitude balloon flight. The teams’ student-built data vaults will be safely dropped from around 120,000 feet with the capability to target a specific landing point on the ground to manage risk. The missions participating in the Antarctic campaign are Purdue University’s Purdue DRAGONfly, and University of Notre Dame’s IRIS v3.
NASA’s zero-pressure balloons, used in the Antarctic campaign, are made of a thin plastic film and are capable of lifting up to 8,000 pounds of payload and equipment to altitudes above 99.8% of Earth’s atmosphere. Zero-pressure balloons, which typically have a shorter flight duration from the loss of gas during the day-to-night cycle, can support long-duration missions in polar regions during summer. The constant daylight of Antarctica’s austral summer and stable stratospheric wind conditions allow the balloon missions to remain in near space for days to weeks, gathering large amounts of scientific data as they circle the continent.
NASA’s Long Duration Balloon camp is located about eight miles from the U.S. National Science Foundation’s McMurdo Station on Antarctica’s Ross Ice Shelf. NASA/Scott Battaion NASA’s Wallops Flight Facility in Virginia manages the agency’s scientific balloon flight program with 10 to 15 flights each year from launch sites worldwide. Peraton, which operates NASA’s Columbia Scientific Balloon Facility in Palestine, Texas, provides mission planning, engineering services, and field operations for NASA’s scientific balloon program. The Columbia team has launched more than 1,700 scientific balloons over some 40 years of operations. NASA’s balloons are fabricated by Aerostar. The NASA Scientific Balloon Program is funded by the NASA Headquarters Science Mission Directorate Astrophysics Division. NASA balloon launch operations from Antarctica receive logistical support from the U.S. National Science Foundation’s Office of Polar Programs, which oversees the U.S. Antarctic Program.

Sols 4331-4333: Today’s Rover ABC – Aurora, Backwards Driving, and Chemistry, with a Side of Images
This image shows just how variable and interesting the terrain is in the area that NASA’s Mars rover Curiosity is currently investigating. Curiosity captured this long-distance Remote Micro Imager (RMI) image using the Chemistry & Camera (ChemCam) aboard the rover on sol 4329 — Martian day 4,329 of the Mars Science Laboratory mission — on Oct. 10, 2024 at 02:30:12 UTC. NASA/JPL-Caltech/LANL Earth planning date: Friday, Oct. 11, 2024
This blogger is in the United Kingdom, just north of London, where we yesterday had beautiful night skies with a red aurora that was even visible with the unaided eye, and looked stunning on photographs. That reminded me of the solar storm that made it all the way to Mars earlier this year. Here is my colleague Deborah’s blog about it: “Aurora Watch on Mars.” And, of course, that was a great opportunity to do atmospheric science and prepare for future crewed missions, to assess radiation that future astronauts might encounter. You can read about it in the article, “NASA Watches Mars Light Up During Epic Solar Storm.” But now, back from shiny red night skies north of London, and auroras on Mars six months ago, to today’s planning!
Power — always a negotiation! Today, I was the Science Operations Working Group chair, the one who has to watch for the more technical side of things, such as the question if all the activities will fit into the plan. Today there were many imaging ideas to capture the stunning landscape in detail with Mastcam and very close close-ups with the long-distance imaging capability of ChemCam (RMI). Overall, we have two long-distance RMIs in the plan to capture the details of the ridge we are investigating. You can see in the accompanying image an example from last sol of just how many stunning details we can see. I so want to go and pick up that smooth white-ish looking rock to find out if it is just the light that makes it so bright, or if the surface is different from the underside… but that’s just me, a mineralogist by training, used to wandering around a field site! Do you notice the different patterns — textures as we call them in geology — on the rocks to the left of that white-ish rock and the right of it? So much stunning detail, and we are getting two more RMI observations of 10 frames each in today’s plan! In addition there are more than 80 Mastcam frames planned. Lots of images to learn from!
Chemistry is also featuring in the plan. The rover is stable on its wheels, which means we can get the arm out and do an APXS measurement on the target “Midnight Lake,” which MAHLI also images. The LIBS investigations are seconding the APXS investigation on Midnight Lake, and add another target to the plan, “Pyramidal Pinnacle.” On the third sol there is an AEGIS, the LIBS measurement where the rover picks its own target before we here on Earth even see where it is! Power was especially tight today, because the CheMin team does some housekeeping, in particular looking at empty cells in preparation for the next drill. The atmosphere team adds many investigations to look out for dust devils and the dustiness of the atmosphere, and APXS measures the argon content of the atmosphere. This is a measure for the seasonal changes of the atmosphere, as argon is an inert gas that does not react with other components of the atmosphere. It is only controlled by the temperature in various places of the planet — mainly the poles. DAN continues to monitor water in the subsurface, and RAD — prominently featured during the solar storm I was talking about earlier — continues to collect data on the radiation environment.
Let’s close with a fun fact from planning today: During one of the meetings, the rover drivers were asked, “Are you driving backwards again?” … and the answer was yes! The reason: We need to make sure that in this rugged terrain, with its many interesting walls (interesting for the geologists!), the antenna can still see Earth when we want to send the plan. So the drive on sol 4332 is all backwards. I am glad we have hazard cameras on the front and the back of the vehicle!
