CALET captures charge-sign dependent cosmic ray modulation
The movement of cosmic ray particles across space, such as electrons and protons, is influenced by the Sun's magnetic field, causing fluctuations in the intensity of galactic cosmic rays (GCRs) reaching Earth in response to the solar cycle. During periods of low solar activity, such as the solar minimum, more GCRs have been observed to reach Earth compared to that for periods of high solar activ HawkEye 360's Cluster 7 begins operation in record time
HawkEye 360 Inc., the world's leading defense technology company for space-based radio frequency (RF) data and analytics, reports that its Cluster 7 satellites have begun operation. This latest satellite trio achieved initial operating capability in record time after successfully launching into orbit on April 15, 2023.
A new 300MHz whip antenna provides better coverage in the 270MHz - 330M LEO PNT satellite signal simulator debuts at JNC 2023 conference
Spirent will demonstrate the first fully-certified Xona satellite constellation simulator, SimXona, at the 2023 Joint Navigation Conference (JNC), June 12-15, 2023, in San Diego, CA. Organized by the Institute of Navigation, JNC is the largest U.S. military positioning, navigation, and timing (PNT) conference, with government, defense, and industry participation.
Spirent, the leading globa CNES, E-Space complete next-generation low earth orbit constellation study
E-Space has completed a five-month feasibility study, commissioned by the French Space Agency, Centre National D'Etudes Spatiales (CNES). The study aimed at assessing and validating the technical capabilities of the E-Space satellite system (space platform, communication payload, guidance, navigation and control (GNC) and user terminal) as well as the long-term viability of the Company's underly Capella Space awarded multi-year blanket purchase agreement by NASA
Capella Space, an American space tech company and the world's leading provider of commercial Synthetic Aperture Radar (SAR) imagery for a wide range of government, commercial and scientific applications, has been awarded a five year blanket purchase agreement (BPA) by NASA's Earth Science Division for the purchase of its high resolution SAR imagery and data for evaluation to determine their suit Long missions, frequent travel take a toll on astronauts' brains, study shows
As we enter a new era in space travel, a study looking at how the human brain reacts to traveling outside Earth's gravity suggests frequent flyers should wait three years after longer missions to allow the physiological changes in their brains to reset.
Researchers studied brain scans of 30 astronauts from before and after space travel. Their findings, reported in Scientific Reports, revea Chief designer details how future lunar landing works
China is working on a rocket for its moon landing mission, which will send a manned spaceship and a lander to lunar orbit in two separate flights, chief designer of the country's manned space program Zhou Jianping revealed.
The spaceship will send the taikonauts to lunar orbit and dock with the lunar lander. The lander will subsequently carry the taikonauts to the moon's surface. After the How and why NASA gives a name to every spot it studies on Mars
Martian maps are full of monikers recognizing places on Earth, explorers, and even cartoon characters.
NASA's Perseverance rover is currently investigating rock outcrops alongside the rim of Mars's Belva Crater. Some 2,300 miles (3,700 kilometers) away, NASA's Curiosity rover recently drilled a sample at a location called "Ubajara." The crater bears an official name; the drill location is identified by a nickname, hence the quotation marks.
Both names are among thousands applied by NASA missions not just to craters and hills, but also to every boulder, pebble, and rock surface they study.
Ariane 6 joint update report, 8 June 2023
As anticipated in May, here is an update of the progress being made towards inaugural flight of the new Ariane 6 launcher.
The next update is expected end July.
Frequent lengthy space travel takes a toll on astronauts' brains, study shows
As we enter a new era in space travel, a study looking at how the human brain reacts to traveling outside Earth's gravity suggests frequent flyers should wait three years after longer missions to allow the physiological changes in their brains to reset.
Researchers studied brain scans of 30 astronauts from before and after space travel. Their findings, reported in Scientific Reports, reveal that the brain's ventricles expand significantly in those who completed longer missions of at least six months, and that less than three years may not provide enough time for the ventricles to fully recover.
Ventricles are cavities in the brain filled with cerebrospinal fluid, which provides protection, nourishment and waste removal to the brain. Mechanisms in the human body effectively distribute fluids throughout the body, but in the absence of gravity, the fluid shifts upward, pushing the brain higher within the skull and causing the ventricles to expand.
"We found that the more time people spent in space, the larger their ventricles became," said Rachael Seidler, a professor of applied physiology and kinesiology at the University of Florida and an author of the study.
