N-210 STOLAND Simulation: Analog to digital and digital to analog coverter

At Mars North Pole is a dome of icy layers ranging up to 2 kilometers thick, roughly analogous to the Earth ice caps in Greenland or Antarctica. This image is from NASA Mars Reconnaissance Orbiter.

Unfrozen brine in cryopegs and fracture networks provides habitats for the survival and growth of organisms both within and under frozen rocky materials on Earth and, by analogy, could provide habitats on Mars.

This NASA Lunar Reconnaissance Orbiter LRO image is of the summit crater of Hortensius Dome Phi. Summit craters of all the Hortensius Domes show no raised rims and are not circular, indicating they are analogous to volcanic calderas.

Reeves Electronic analog computer (REAC), Ames' first electronic computing machine, was acquired in 1949 to perform control simulation analysis.

The eastern shore of Lake Salda in Turkey is a good analog for what an ancient lake may have looked like at Jezero Carter on Mars. The white sands and rocks are carbonate minerals that precipitated in the lake. The terraces on the right are old shorelines from when the lake levels were higher, where dried-out sediments have now cemented. These types of deposits might be present along the former shorelines at Jezero. What's more, these deposits might contain signs of microbes, if they ever existed on the Red Planet. NASA's Mars 2020 Perseverance mission will search for signs of ancient life in an dried-up lakebed on the surface of Mars. https://photojournal.jpl.nasa.gov/catalog/PIA24375

Harry Mergler stands at the control board of a differential analyzer in the new Instrument Research Laboratory at the National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory. The differential analyzer was a multi-variable analog computation machine devised in 1931 by Massachusetts Institute of Technology researcher and future NACA Committee member Vannevar Bush. The mechanical device could solve computations up to the sixth order, but had to be rewired before each new computation. Mergler modified Bush’s differential analyzer in the late 1940s to calculate droplet trajectories for Lewis’ icing research program. In four days Mergler’s machine could calculate what previously required weeks. NACA Lewis built the Instrument Research Laboratory in 1950 and 1951 to house the large analog computer equipment. The two-story structure also provided offices for the Mechanical Computational Analysis, and Flow Physics sections of the Physics Division. The division had previously operated from the lab’s hangar because of its icing research and flight operations activities. Mergler joined the Instrument Research Section of the Physics Division in 1948 after earning an undergraduate degree in Physics from the Case Institute of Technology. Mergler’s focus was on the synthesis of analog computers with the machine tools used to create compressor and turbine blades for jet engines.

A group of researchers from NASA's Jet Propulsion Laboratory and other institutions spent two weeks on a glacier in Alaska in July 2023 for a project called ORCAA (Ocean Worlds Reconnaissance and Characterization of Astrobiological Analogs). Known as an analog mission, the project is working to answer science questions and test technology in preparation for a potential future mission to explore the surface or subsurface of icy moons like Jupiter's Europa and Saturn's Enceladus. Working at the Juneau Icefield, in coordination with the Juneau Icefield Research Project, the team used a hot-water drill to make a narrow hole in the glacier, melting its way progressively deeper. After three days, the drill reached bedrock, 890 feet (272 meters) below the surface. Science instruments were then sent down the borehole to take a variety of measurements and characterize the water environment. In 2025, the ORCAA team will return to the icefield and target a subglacial lake (a body of water inside the glacier) that has similarities to a reservoir scientists believe exists a few kilometers beneath the icy surface of Europa. ORCAA is funded by NASA's Planetary Science and Technology from Analog Research (PSTAR) program. https://photojournal.jpl.nasa.gov/catalog/PIA26345

This EREP photograph of the Uncompahgre Plateau area of Colorado illustrates the land use classification using the hierarchical numbering system to depict land forms and vegetative patterns. The numerator is a three-digit number with decimal components identifying the vegetation analog or land use conditions. The denominator uses a three-component decimal system for landscape characterization.

To lay the groundwork for NASA's VERITAS mission (Venus Emissivity, Radio science, InSAR, Topography, And Spectroscopy), members of the mission's international science team traveled in August 2023 to Iceland, using the island as a stand-in, or analog, for Venus. Using several techniques, the team studied a variety of rocky terrain, including this lava field featuring new rock from a recent flow, to better understand what the VERITAS mission will "see" when it studies Venus' surface. The VERITAS orbiter will peer through the planet's thick atmosphere with a suite of powerful science instruments to create global maps of the planet's surface – including topography, radar images, rock type, and gravity measurements – as well as detect surface changes. VERITAS is designed to understand what processes are currently active, search for evidence of past and current interior water, and understand the geologic evolution of the planet, illuminating how rocky planets throughout the galaxy evolve. https://photojournal.jpl.nasa.gov/catalog/PIA25838

jsc2024e006095 (11/8/2023) --- Image of the KASHIWA flight units. KASHIWA, developed by the Growing Advanced and Refined space Development ENgineering succession and under the satellite (GARDENs) program is a project from Chiba Institute of Technology. The KASHIWA mission is to demonstrate stereo cameras for ranging, to demonstrate the APRS (Automatic Packet Reporting System) for digipeating through the satellite, to demonstrate analog audio using geomagnetic sensor and earth observation with camera.

An image of the F-16XL #1 during its functional flight check of the Digital Flight Control System (DFCS) on December 16, 1997. The mission was flown by NASA research pilot Dana Purifoy, and lasted 1 hour and 25 minutes. The tests included pilot familiarly, functional check, and handling qualities evaluation maneuvers to a speed of Mach 0.6 and 300 knots. Purifoy completed all the briefed data points with no problems, and reported that the DFCS handled as well, if not better than the analog computer system that it replaced.

This graphic compares the magnetic fields of Earth and Jupiter, characterizing the field on the surface of each planet in terms of spatial scale, with large scale to the left, and small scale to the right. The linear progression of terms characterizing Earth's field identifies a dynamo core radius at 0.54 planet radius and crustal magnetization at smaller scales. By analogy, the new Jupiter model identifies a dynamo core radius at 0.81 planet radius, in the convective metallic hydrogen just beneath a zone stabilized by helium rain. https://photojournal.jpl.nasa.gov/catalog/PIA25064

This photograph from northwestern New Mexico shows a ridge roughly 30 feet about 10 meters tall that formed from lava filling an underground fracture then resisting erosion better than the material around it did. The dike extends from a volcanic peak (out of view here) called Shiprock in English and Tsé Bit'a'í, meaning "rock with wings," in the Navajo language. It offers an Earth analog for some larger hardened-lava walls on Mars http://photojournal.jpl.nasa.gov/catalog/PIA21266

A model of a tiny, wedge-shaped robot designed to explore subsurface oceans of icy moons, right, sits beside a large waterproof capsule containing electronics and sensors for testing below glacial ice at the Juneau Icefield in Alaska in July 2023. The model, about 5 inches (12 centimeters) long, was 3D-printed to show the final envisioned size of a futuristic NASA mission concept called SWIM, short for Sensing With Independent Micro-swimmers. Led by NASA's Jet Propulsion Laboratory from spring 2021 to fall 2024, SWIM envisions a swarm of dozens of self-propelled, cellphone-size robots exploring the waters of icy moons like Jupiter's Europa and Saturn's Enceladus. Delivered to the subsurface ocean by an ice-melting cryobot, the tiny robots would zoom away to look for chemical and temperature signals that could point to life. The capsule shown here contains the first generation of an ocean composition sensor built for the SWIM robots by a team at Georgia Tech. The final version of the sensor would enable each robot to simultaneously measure temperature, pressure, acidity or alkalinity, conductivity, and chemical makeup. During the Alaska field test, the team lowered the capsule through a borehole in the ice and measured pressure and conductivity down to a depth of 164 feet (50 meters). This field test was conducted as part of a JPL-managed project called ORCAA (Ocean Worlds Reconnaissance and Characterization of Astrobiological Analogs). Known as an analog mission, ORCAA is working to answer science questions and test technology in preparation for a potential future mission to explore the surface or subsurface of icy moons. ORCAA is funded by NASA's Planetary Science and Technology from Analog Research program. SWIM was supported by Phase I and II funding from NASA's Innovative Advanced Concepts program under the agency's Space Technology Mission Directorate. JPL is managed for NASA by Caltech in Pasadena, California. https://photojournal.jpl.nasa.gov/catalog/PIA26424

Italy's Mount Etna and the Aeolian Islands are the focus of this perspective view made from an Advanced Spaceborne Thermal and Emission Radiometer (ASTER) image from NASA's Terra spacecraft overlaid on Shuttle Radar Topography Mission (SRTM) topography. The image is looking south with the islands of Lipari and Vulcano in the foreground and Etna with its dark lava flows on the skyline. Vulcano also hosts an active volcano, the cone of which is prominent. In late October 2002, Etna erupted again, sending lava flows down the north and south sides of the volcano. The north flows are near the center of this view, but the ASTER image is from before the eruption. In addition to the terrestrial applications of these data for understanding active volcanoes and hazards associated with them such as lava flows and explosive eruptions, geologists studying Mars find these data useful as an analog to martian landforms and geologic processes. In late September 2002, a field conference with the theme of Terrestrial Analogs to Mars focused on Mount Etna allowing Mars geologists to see in person the types of features they can only sample remotely. http://photojournal.jpl.nasa.gov/catalog/PIA03370

N-243 Flight and Guidance Centrifuge: Is used for spacecraft mission simulations and is adaptable to two configurations. Configuration 1: The cab will accommodate a three-man crew for space mission research. The accelerations and rates are intended to be smoothly applicable at very low value so the navigation and guidance procedures using a high-accuracy, out-the window display may be simulated. Configuration 2: The simulator can use a one-man cab for human tolerance studies and performance testing. Atmosphere and tempertaure can be varied as stress inducements. This simlator is operated closed-loop with digital or analog computation. It is currently man-rated for 3.5g maximum.

Scientists at NASA's Marshall Space Flight Center in Huntsville, Alabama, clean equipment and prepare for shipment of the ring sheared drop payload currently set for launch on Northrop Grumman 16 the first week in August, 2021. The payload studies the formation of potentially destructive amyloid fibrils, or protein clusters, like those found in the brain tissue of patients battling neurodegenerative diseases. Such illnesses may damage neurons, the drivers of the human nervous system. Experimentation in microgravity provides the opportunity to study amyloid fibril formation in conditions more analogous to those found in the human body than can be studied in a ground-based laboratory environment.

A significant event has occurred in Inca City. The layer of seasonal ice has started to develop long cracks as evidenced by NASA Mars Reconnaissance Orbiter. Fans of dust are emerging from long linear cracks. The cracks form when large plates of ice have no easily ruptured weak spots to release the pressure from gas building up underneath, so the ice simply cracks. There are also more fans on the ridge at the top of the image, and more have appeared in between the araneiforms. We do not have any analogous processes occurring naturally on Earth: this is truly Martian. http://photojournal.jpl.nasa.gov/catalog/PIA18896

This is a view of the Emi Koussi Caldera captured by the Expedition Six Crew Observation (CEO) experiment aboard the International Space Station (ISS). Rising 2.3 km above the surrounding sandstone plains, Emi Koussi is a 6.5 km wide volcano located at the south end of the Tibesti Mountains in the central Sahara desert. The volcano is one of several in the Tibesti massif and has been used as a close analog to the famous Martian volcano Elysium Mons. Major charnels can be seen on volcanoes on both planets that indicate low points in caldera rims where lava spilled out of the pre-collapsed craters.

An engineer at NASA's Jet Propulsion Laboratory is shown here with the fast steering mirror, a component of the Coronagraph Instrument on NASA's Nancy Grace Roman Space Telescope. The mirror can make small movements that correct for slight wobbling of the observatory. The incoming image needs to be perfectly sharp in order for the instrument to suppress light from a star while allowing the light from planets orbiting it to pass through. Although the technologies differ, it's analogous to image stabilization in digital cameras, in which the camera lens moves to counteract the shake of your hands and keep the image sharp. https://photojournal.jpl.nasa.gov/catalog/PIA25437

This image from NASA Terra spacecraft shows Prince Patrick Island, which is located in the Canadian Arctic Archipelago, and is the westernmost Elizabeth Island in the Northwest Territories of Canada. The island is underlain by sedimentary rocks, cut by still-active faults. The streams follow a dendritic drainage system: there are many contributing streams (analogous to the twigs of a tree), which are then joined together into the tributaries of the main river (the branches and the trunk of the tree, respectively). They develop where the river channel follows the slope of the terrain. The image covers an area of 22 by 27 km, was acquired July 2, 2011, and is located at 76.9 degrees north, 118.9 degrees west. http://photojournal.jpl.nasa.gov/catalog/PIA19222
