NASA Spacecraft Crashes Back to Earth in Uncontrolled Reentry - ScienceAlert

On May 10, 2025, a spacecraft built in the Soviet Union to land on Venus came home. Launched in 1972, Cosmos-482 was stranded by a failed upper stage of its rocket and circled Earth for 53 years. In its last days, several space agencies and research groups forecasted when it would fall, and therefore where. Roscosmos later reported that it came down in the Indian Ocean, west of Jakarta.

NASA has confirmed that the Orion heat shield successfully withstood temperatures reaching 2,200 degrees Celsius (4,000 degrees Fahrenheit) while slicing through the atmosphere at almost 48,000 km/h (30,000 mph)—or 39 times the speed of sound. Despite facing extreme asteroid-speed reentry conditions during the Artemis II mission, temperatures inside the crew capsule never exceeded a comfortable 21 degrees Celsius (70 degrees Fahrenheit), keeping the four astronauts safe throughout their return from lunar orbit. The post-flight findings represent a massive engineering triumph for the American space agency, especially after the uncrewed Artemis I test flight in 2022 revealed alarming surface erosion. Critical data now demonstrates that an innovative trajectory adjustment reduced thermal cracking and char loss by a factor of ten, successfully validating the thermal protection system without requiring a physical redesign.

IntroductionHypertension is a major global health concern and a leading cause of morbidity and mortality [1]. It is estimated that more than 19 million annual deaths are attributed to cardiovascular disease (CVD) worldwide [2]. In Japan, high blood pressure (BP) has been consistently identified as a strong risk factor for the national burden of CVD, in terms of notable incidence, mortality, direct/indirect healthcare costs, and quality-adjusted life years (QALYs) associated with this condition [3, 4]. Although age-specific mean BP declined in Japan over recent decades [5], hypertension remains a critical public health issue, particularly because of the rapid aging population. The proportion of individuals aged ≥65 years is projected to reach approximately 35% by 2040 in Japan [6], highlighting a potentially higher future burden of hypertension in this country. While the prevalence of hypertension increases with age, population aging may offset the benefits of declining BP levels in each age group. As a result, the future burden of hypertension in Japan remains uncertain.

The number of foreigners holding business manager visas who left Japan without applying for reentry permits nearly quadrupled in the first half of 2026 from a year earlier,…

AbstractChronic pain (CP) affects more than 30% of the global population and is often accompanied by significant cognitive impairments. Although an increasing number of studies have focused on the pathological mechanisms associated with chronic pain-induced cognitive impairments, most have concentrated on the stage after the onset of cognitive impairments. Currently, the course by which chronic pain induces cognitive impairment has not been fully reported. Therefore, single-cell RNA sequencing were conducted in this study in order to map the mice hippocampus altas before and after cognitive impairments induced by spared nerve injury (SNI) on days 3, 7, 14, and 21. After quality control screening, 53852 out of 64207 cells from 11 samples were retained for subsequent analysis. The reliability of the sequencing data was verified through analysis of various evaluation indicators and sequencing alignment rates.
