NASA's Artemis program is getting ready for Artemis II, the next mission that will use the Orion spacecraft to transport humans around the Moon. For the first time since the Apollo era, humans will venture outside of low Earth orbit during the 10-day Artemis II mission. NASA is working to send people back to the moon with Artemis II. NASA has established a new Orion Mission Evaluation Room (MER) at Johnson Space Center to support this mission. Teams of engineers will work in this room to keep an eye on Orion's systems while it is in flight. This facility, which is manned 24/7, will contribute to the crew's safety. Purpose and Function of the Orion Control Room According to NASA, the Orion Mission Evaluation Room (MER) acts as a real-time engineering support hub for the Artemis II mission while NASA's flight controllers pilot Orion from the main control room. The MER team compares live telemetry to the spacecraft's expected performance and troubleshoots any anomalies...

Samsung is rolling out a new update for SmartThings Family Care. The South Korean tech giant introduced the service last year, which allows users to link TVs and home appliances through its global SmartThings platform to provide activity updates, medication and appointment reminders, and location-based alerts. The SmartThings Family Care service offers practical support for caregivers and care recipients who do not live together. The latest update to the service is said to streamline the process. Users can now customise settings more precisely to suit their family's lifestyle and needs. Samsung SmartThings Family Care Update The latest SmartThings Family Care update makes it easy for inexperienced family members to install and set up Family Care independently, the company revealed on Thursday. Caregivers can share an invitation link containing step-by-step guidance to help others join the platform. The update is available for Samsung Galaxy smartphones running Android 11 or higher,...

The 1977 “Wow!” signal from the Big Ear radio telescope in Ohio has long puzzled astronomers. It was a brief, narrow-band radio burst lasting 72 seconds – so striking that astronomer Jerry Ehman famously wrote “Wow!” on the data printout. Despite decades of study, its origin remained unknown and no repeat signal has been found. In 2025, a multi-author international team re-examined these decades-old analog records using advanced computing methods. Their paper provides corrections and new insights into the signal and its possible origin. Modern Data Analysis of the Wow! Signal According to the study, volunteers digitized old Big Ear telescope logs using optical-character-recognition software. This allowed detailed recalculation of the signal's parameters. They narrowed the sky region (boosting location certainty by two-thirds) and adjusted the frequency from 1420.4556 to 1420.726 MHz. In practical terms, that frequency change implies the radio source was moving faster than previousl...

Bitcoin Asia 2025, one of the most significant international conferences focused on Bitcoin and digital currencies, will commence on the 28th and 29th of August in Hong Kong. Around 15,000 people are expected to attend the event, making it the second-largest Bitcoin event in the world. This is a key indicator of Hong Kong's growing stature as a global hub for digital assets and its commitment to attracting both institutional and retail participation. Over 200 speakers will attend and participate in various Bitcoin Asia 2025 events, including Blockstream CEO Adam Back, Binance founder Chanpeng Zhao (CZ), and Balaji Srinivasan. Policymakers, Investors, and World Leaders Will Examine Bitcoin Adoption, Regulation, and More Regulation clarity, institutional adoption, and the future of the digital economy in Asia are all on the agenda of this event. “Bitcoin Asia 2025 will be a 15,000-person event, a historic milestone for Bitcoin in Asia. The energy, adoption, and innovation happening h...

A research team at the University of Minnesota Twin Cities has identified the first new type of plasma wave in Jupiter's aurora, a finding that broadens our understanding of planetary magnetic environments. The discovery, based on data from NASA's Juno spacecraft, not only enhances knowledge of Jupiter's polar activity but also offers insights into “alien aurora” on other planets. The researchers think such discoveries go some way to explaining how magnetic fields shield atmospheres from being strafed by destructive solar particles, with Earth's auroras providing a natural counterpart for Jupiter's more complex system. Juno Mission Uncovers Unprecedented Plasma Wave in Jupiter's Invisible Auroras According to a report published in Physical Review Letters, the crack came after Juno flew close to Jupiter's north pole on a low orbit, the closest a spacecraft has come to the polar region of the gas giant, and scientists for the first time were able to look at co...

A ginormous solar tornado and a massive eruption of plasma have been observed occurring at the same time on the sun — a phenomenon so strange and rare that it's challenging previously held theories. Both phenomena were snapped in the same photograph by the Institute of Space Science in Romania researcher Maximilian Teodorescu on Aug. 20. Solar tornadoes and plasma eruptions seem dramatic but are in fact the offshoots of changing in the sun's invisible magnetic field. They're unrelated, but to view them together is extraordinary and a thrill for scientists. Why Solar Tornadoes and Eruptions Matter As per Live Science, the solar tornado was enormous — it clocked in at about 130,000 kilometers (nearly 80,000 miles) tall. That's higher than stacking over 10 Earths on top of one another. Solar tornadoes tend to be much smaller, around 25,000 to 100,000 kilometers high. In addition to it, Teodorescu also imaged an eruptive prominence that measured some 200,000 kilometers acro...

On August 21, 2025, a U.S. military space plane, the X-37B Orbital Test Vehicle, is scheduled to launch its eighth mission. Though a few additional things are still classified, one experiment in particular has captured the imagination: a quantum inertial sensor meant to serve as a major new alternative to GPS. This would revolutionise navigation in areas where satellite-based systems are not available or have been degraded. Whether in deep outer space, under the sea, or in hotspots on land, there is an eagerly awaited answer for vulnerabilities in global positioning systems. X-37B Space Plane to Pioneer Quantum Navigation as GPS Alternative in Space According to reports, satellite GPS powers everything from civilian smartphones to commercial aviation, but it has critical weaknesses. Signals degrade in space, can't get through water, and are subject to jamming and spoofing in contested environments. Researchers said the X-37B's quantum inertial sensor relies on atom interferomet...

Chinese astronauts Chen Dong and Wang Jie completed a 6.5-hour spacewalk on Aug. 15 to bolster the Tiangong space station's debris shield. As part of the Shenzhou 20 crew, they also inspected and maintained exterior equipment during the EVA. State media noted this was at least the crew's second effort to install “debris protection” devices on the station (following a May 22 spacewalk). The EVA concluded at 9:27 a.m. EDT, making it Chen Dong's sixth spacewalk (the most by any Chinese astronaut) and the third for Shenzhou 20 overall. Launched from Jiuquan on April 24, the crew is now about halfway through its six-month mission. Debris Mitigation and International Cooperation: According to a 2022 government white paper, chinese officials emphasize space debris as a global concern. It pledges stronger space-traffic control and improved debris tracking and warning systems. It notes that China now passivates spent rocket stages and actively de-orbits retired spacecraft (such as t...

The most distant object in the universe ever discovered, Earendel, might not in fact be a lone star as scientists initially assumed. It was spotted on 2022 by the Hubble Space Telescope and appeared to have evolved just 900 million years after the Big Bang, at a time when the universe was a mere infant. But fresh data from the newly launched James Webb Space Telescope (JWST) indicate that Earendel may not be a massive solitary star, but rather a small group of them — a star cluster. How We Can See It As per Live Science report , Earendel is located in the Etendeka galaxy of the Sunrise Arc, some 12.9 billion light-years from Earth. We can see it thanks to the effect of a special one known as gravitational lensing. The lensing occurs when a massive galaxy cluster warps and amplifies the light from objects situated much farther away. In this one, Earendel's light was 4,000 times as bright, shining in a way that astronomers would be able to catch it. Such rare alignments lead scientis...
