Abstract:

With the growing human interest in space exploration, understanding the oxidative damage effects of microgravity on somatic and germ cells and their underlying mechanisms has become a pivotal scientific challenge for ensuring reproductive health during long-term space missions. In this review, we comprehensively summarize the molecular mechanisms of microgravity-induced oxidative stress, advanced detection methods, and potential protective strategies for germ cells. The evidence demonstrates that microgravity substantially compromises germ cell viability and embryonic developmental potential b

Abstract:

Among possible causes of visual impairment or headache experienced by astronauts in microgravity or postflight and that hamper their performance, elevated intracranial pressure (ICP) has been invoked but never measured for lack of noninvasive methods. The goal of this work was to test two noninvasive methods of ICP monitoring using in-ear detectors of ICP-dependent auditory responses, acoustic and electric, in acute microgravity afforded by parabolic flights. The devices detecting these responses were handheld tablets routinely used in otolaryngology for hearing diagnosis, which were customize

Abstract:

Four-dimensional or time-lapse microgravity monitoring has been used effectively on volcanoes for decades to characterize the changes in subsurface volcanic systems. With measurements typically lasting from a few days to weeks and then repeated a year later, the spatial resolution of theses studies is often at the expense of temporal resolution and vice versa. Continuous gravity studies with one to two instruments operating for a short period of time (weeks to months) have shown enticing evidence of very rapid changes in the volcanic plumbing system (minutes to hours) and in one case precursor

Abstract:

Extended exposure to radiation, microgravity, and isolation during space exploration has significant physiological, structural, and psychosocial effects on astronauts, and particularly their central nervous system. To date, the use of brain monitoring techniques adopted on Earth in pre/post-spaceflight experimental protocols has proven to be valuable for investigating the effects of space travel on the brain. However, future (longer) deep space travel would require some brain function monitoring equipment to be also available for evaluating and monitoring brain health during spaceflight. Here,

Abstract:

The pressing need to safeguard the health of astronauts aboard the International Space Station (ISS) necessitates constant and rigorous microbial monitoring. Recognizing the shortcomings of traditional culture-based methods, NASA is deliberating the incorporation of molecular-based techniques. The challenge, however, lies in developing and validating effective methods for concentrating samples to facilitate this transition. This study is dedicated to investigating the potential of an ISS Smart Sample Concentrator (iSSC) as an innovative concentration method. First, the iSSC system and its comp

Abstract:

In light of the potential effects of spaceflight on the anterior segment of the eye, there is a pressing need for anterior segment imaging to be available and accessible to monitor astronauts’ ocular health, including alterations to the cornea and lens. We aim to highlight the clinical basis and need for anterior segment imaging for astronauts. We explore the impacts of spaceflight-associated hazards, including microgravity and radiation, on astronauts’ risk of developing anterior segment pathology including risk of ocular trauma, infection, dry eye symptoms, cataracts, and possibly additional

Abstract:

(1) Background: One effect of microgravity on the human body is fluid redistribution due to the removal of the hydrostatic gravitational gradient. These fluid shifts are expected to be the source of severe medical risks and it is critical to advance methods to monitor them in real-time. One technique to monitor fluid shifts captures the electrical impedance of segmental tissues, but limited research is available to evaluate if fluid shifts in response to microgravity are symmetrical due to the bilateral symmetry of the body. This study aims to evaluate this fluid shift symmetry. (2) Methods: S

Abstract:

Dalam proyek CCS, monitoring bawah permukaan perlu dilakukan dengan baik agar CO2 yang diinjeksikan dapat tersimpandengan aman di dalam reservoir. Salah satu metode geofisika yang dapat digunakan untuk monitoring bawah permukaan adalah metode gravity. Dengan membuat model sintetik volume reservoir, tekanan dan temperatur bawah permukaan, serta perhitungan aliran fluida pada rentang waktu tertentu, dapat diprediksi radius penyebaran CO2 dan distribusi densitasnya di dalam reservoir. Radius penyebaran dan kontras densitas yang didapatkan, digunakan untuk pemodelan ke depan time-lapse microgravit

Abstract:

An ultrasound sensor system based on the transmission-mode approach is developed to enable the monitoring and sensing of cryogenic liquids and gases—especially gaseous bubbles and gas-liquid interfaces in liquid nitrogen (LN2). Common sensors do not meet requirements of cryogenic and microgravity-environments. Therefore, a special encapsulation design for the optimization of the electrical connection and the mechanical coupling of the ultrasound sensors is needed. The ultrasound system is qualified in LN2 and is able to measure bubbles (size and location) and fill levels with a high spatial re

Functioning of hearing organs and ENT microflora composition were investigated in 10 healthy male subjects (25–36 y.o.) who volunteered for a 7-day dry immersion as a model of the physiological effects of microgravity. The functional state of the hearing organs was assessed with the registration of distortion product oto-acoustic emission (DPOAE), and tympanometry. Specifically, assessed were the signal-to-noise ratio (SNR) of the oto-acoustic response (dB), middle ear pressure (daPa) and tympanogram maximal compliance (ml).

Abstract:

Last year, events accelerated several trends in the energy landscape. Oil and gas prices have remained low, and the industry is focusing more strongly on reducing costs and increasing operational efficiency. Reducing costs is not only about cutting costs today but also about reducing the life-cycle cost per barrel. Implementing innovative technologies that increase recovery requires a small investment but can bring large rewards. Advances in sensor accuracy, computing power, and data analytics unlock innovative use cases for technology for mapping subsurface movements of fluids. Very different
