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.

Hubble Examines Stars Ensconced in a Cocoon of Gas
NGC 460 is an open cluster of stars within a greater collection of nebulae and star clusters known as the N83-84-85 complex. NASA, ESA, and C. Lindberg (The Johns Hopkins University); Processing: Gladys Kober (NASA/Catholic University of America)

An open cluster of stars shines through misty, cocoon-like gas clouds in this Hubble Space Telescope image of NGC 460.
NGC 460 is located in a region of the Small Magellanic Cloud, a dwarf galaxy that orbits the Milky Way. This particular region contains a number of young star clusters and nebulae of different sizes ― all likely related to each other. The clouds of gas and dust can give rise to stars as portions of them collapse, and radiation and stellar winds from those hot, young bright stars in turn shape and compress the clouds, triggering new waves of star formation. The hydrogen clouds are ionized by the radiation of nearby stars, causing them to glow.
The NGC 460 star cluster resides in one of the youngest parts of this interconnected complex of stellar clusters and nebulae, which is also home to a number of O-type stars: the brightest, hottest and most massive of the normal, hydrogen-burning stars (called main-sequence stars) like our Sun. O-type stars are rare ― out of more than 4 billion stars in the Milky Way, only about 20,000 are estimated to be O-type stars. The area that holds NGC 460, known as N83, may have been created when two hydrogen clouds in the region collided with one another, creating several O-type stars and nebulae.
Open clusters like NGC 460 are made of anywhere from a few dozen to a few thousand stars loosely knitted together by gravity. Open clusters generally contain young stars, which may migrate outward into their galaxies as time progresses. NGC 460’s stars may someday disperse into the Small Magellanic Cloud, one of the Milky Way’s closest galactic neighbors at about 200,000 light-years away. Because it is both close and bright, it offers an opportunity to study phenomena that are difficult to examine in more distant galaxies.
Six overlapping observations from a study of the gas and dust between stars, called the interstellar medium, were combined to create this Hubble image. The study aims to understand how gravitational forces between interacting galaxies can foster bursts of star formation. This highly detailed 65 megapixel mosaic includes both visible and infrared wavelengths. Download the 400 MB file and zoom in to see some of the intricacies captured by Hubble.
