Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA uses radio frequency (RF) for a variety of tasks in space, including communications. The Europa Clipper RF panel — the box with the copper wiring near the top — will send data carried by radio waves through the spacecraft between the electronics and eight antennas. Credit: NASA Even before we’re aware of heart trouble or related health issues, our bodies give off warning signs in the form of vibrations. Technology to detect these signals has ranged from electrodes and patches to watches. Now, an innovative wall-mounted technology is capable of monitoring vital signs. Advanced TeleSensors Inc. developed the Cardi/o Monitor with an exclusive license from NASA’s Jet Propulsion Laboratory in Southern California.
Over the course of five years, NASA engineers created a small, inexpensive, contactless device to measure vital signs, a challenging task partly because monitoring heart rate requires picking out motions of about one three-thousandth of an inch, which are easily swamped by other movement in the environment.
By the late 1990s, hardware and computing technology could meet the challenge, and the NASA JPL team created a prototype the size of a thick textbook. It would emit a radio beam toward a stationary person, working similarly to a radar, and algorithms differentiated cardiac and respiratory activity from the “noise” of other movements.
When Sajol Ghoshal, now CEO of Austin, Texas-based Advanced TeleSensors, participated in a demonstration of the prototype, he saw the potential for in-home monitoring. By then, developing an affordable device was possible due to the miniaturization of sensors and computing technology.
The Cardi/o vital sign monitor uses NASA-developed technology to continually monitor vital signs. The data collected can be sent directly to medical care providers, cutting down on the number of home healthcare visits. Credit: Advanced TeleSensors Inc. The Cardi/o Monitor is 3 inches square and mounts to a ceiling or wall. It can detect vital signs from up to 10 feet. Multiple devices can be scattered throughout a house, with a smartphone app controlling settings and displaying all data on a single dashboard. The algorithms NASA developed detect heartbeat and respiration, and the company added heart rate variability detection that indicates stress and sleep apnea.
If there’s an anomaly, such as a dramatic heart rate increase, an alert in the app calls attention to the situation. Up to six months of data is stored in a secure cloud, making it accessible to healthcare providers. This limits the need for regular in-person visits, which is particularly important for conditions such as infectious diseases, which can put medical professionals and other patients at risk.
Through the commercialization of this life-preserving technology, NASA is at the heart of advancing health solutions.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The space shuttle Endeavour is seen on launch pad 39a as a storm passes by prior to the rollback of the Rotating Service Structure (RSS), Thursday, April 28, 2011, at Kennedy Space Center in Cape Canaveral, Fla. During the 14-day mission, Endeavour and the STS-134 crew will deliver the Alpha Magnetic Spectrometer (AMS) and spare parts including two S-band communications antennas, a high-pressure gas tank and additional spare parts for Dextre. Launch is targeted for Friday, April 29 at 3:47 p.m. EDT.NASA It is important to protect humans from unintended electrical current flow during spaceflight. The thresholds for contact electrical shock are well established, and standards and requirements exist that minimize the probability of contact electrical shock. Current thresholds were chosen (vs. voltage thresholds) because body impedance varies depending on conditions such as wet/dry, AC/DC, voltage level, large/small contact area, but current thresholds and physiological effects do not change. By addressing electrical thresholds, engineering teams are able to provide the appropriate hazard controls, usually through additional isolation (beyond the body’s impedance), current limiters, and/or modifying the voltage levels. Risk assessment determined that the probability of an event was extremely low, and the most serious consequence is expected to be involuntary muscle contraction.
Lightning strikes the Launch Pad 39B protection system as preparations for launch of NASA’s Space Launch System (SLS) rocket with the Orion spacecraft aboard continue, Saturday, Aug. 27, 2022, at NASA’s Kennedy Space Center in Florida. NASA’s Artemis I flight test is the first integrated test of the agency’s deep space exploration systems: the Orion spacecraft, SLS rocket, and supporting ground systems. Launch of the uncrewed flight test is targeted for no earlier than Aug. 29 at 8:33 a.m. ET. Photo Credit: (NASA/Bill Ingalls) Directed Acyclic Graph Files

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Astronauts Michael R. (Rich) Clifford and Linda M. Godwin, the assigned space-walking mission specialists for STS-76, go through a “pre-breathing” period on the Space Shuttle Atlantis’ middeck. This practice is normal procedure for space-walkers in preparation for their Extravehicular Activity (EVA) and the wearing of their Extravehicular Mobility Units (EMU). The photograph was taken with a 35mm camera by one of the crew members. Human exploration missions will require robust, flexible Extravehicular Activity (EVA) architecture protocols that include the use of a reduced-pressure cabin atmosphere enabling staged denitrogenation. Use of this atmosphere could result in compromised health and performance to the crewmember due to exposure to mild hypobaric hypoxia; of most concern are the potential effects on the increased intracranial pressure, visual impairment, cognitive performance, sensorimotor dysfunction, oxidative damage, and sleep quality. In addition to hypobaric hypoxia associated with staged denitrogenation, there are additional factors that can result in hypoxic exposure to the crewmember, such as cabin depressurization, Environmental Control, and Life Support System (ECLSS) failure, toxic exposure, or crewmember illness/injury.
Jan Zysko (left) and Rich Mizell (right) test a Personal Cabin Pressure Altitude Monitor in an altitude chamber at Tyndall Air Force Base in Florida. Zysko invented the pager-sized monitor that alerts wearers of a potentially dangerous or deteriorating cabin pressure altitude condition, which can lead to life-threatening hypoxia. Zysko is chief of the KSC Spaceport Engineering and Technology directorate’s data and electronic systems branch. Mizell is a Shuttle processing engineer. The monitor, which has drawn the interest of such organizations as the Federal Aviation Administration for use in commercial airliners and private aircraft, was originally designed to offer Space Shuttle and Space Station crew members added independent notification about any depressurizationNASA Directed Acyclic Graph Files

On March 26, 2020, a French astronomer Mark Carlotto used a telescope to capture a video showing the moon at night. Dr. M. Carlotto is a specialist in digital video analysis of space objects. The video shows three objects rising above the Moon’s limb, flying across the lunar surface and disappearing in the Moon’s shadow.
The fact that some of these objects are so clearly visible and close enough to the moon to be able to cast noticeable shadows immediately suggests that they are quite large. Using the large Endymion crater as a benchmark, the sizes of the objects were determined.
The size of the object flying over Endymion is about 5 miles long and about 1 to 3 miles wide. The other two objects appear to be comparable in size.
By measuring the displacement of the object it appears that the object is traveling at about 31 mps. It is traveling more than 30 times faster than if it were in lunar orbit.
A paper was recently published that attempts to prove that the original video is a fake. Arxiv.org analyzed the video (not included in the analysis) but extracted and provided three images of the recorded objects for examination, as seen above, and they then conducted calculations to verify its authenticity.
Despite government and space agency denials of UFO existence, photographic evidence and subsequent analysis suggest the presence of large extraterrestrial craft near the Moon and elsewhere in space.View the full article
