Boeing Starliner capsule's first crewed test flight postponed at last minute
Boeing's Starliner space capsule's inaugural crewed test flight faced another delay due to a technical issue, halting the countdown for at least 24 hours. The mission, carrying two astronauts to the ISS, is crucial for Boeing to compete with SpaceX in NASA's spaceflight contracts. The delay, caused by a ground system computer triggering an automatic abort command, marks another setback in Starliner's history of delays and glitches. Boeing is striving to catch up with SpaceX, NASA's primary transport to the ISS, and hopes for a successful mission to secure future contracts.

China's arms exports face sharp decline due to defective quality, unreliable performance: Analysts
China's arms exports have declined by nearly a quarter in the last decade due to poor quality and inconsistent performance. The People's Liberation Army is plagued by low-quality weapons, causing a decrease in demand for Chinese weaponry. Hidden costs and lack of technological compatibility have further impacted China's arms exports. While China supplies weapons to over 53 nations, major importers such as Pakistan, Myanmar, and African and Middle Eastern countries have faced issues with Chinese military gear.
Russia's Luna crashes: Why it's so difficult to land on Moon and what ISRO has planned for Chandryaaan-3 safe landing
Russia's first lunar mission in 47 years, Luna-25, crashed into the Moon, leaving India's Chandrayaan-3 mission as the only spacecraft in the race to land on the lunar surface. Landing on the Moon's surface is difficult due to the challenge of descending from lunar orbit to the surface and getting the spacecraft into a vertical position.
Faults found in machines installed to detect movement of trains on tracks; 3000 units already in place in 7 zones
The Railway’s Multi-Section Axle Counter (MSDAC) system, used to detect track occupancy by a train, has been found to be faulty according to a report. The system has been installed and is being tested on a trial basis in approximately 4,000 units bought by the railways for INR5 lakh per unit. Officials have warned that the faults in the units could lead to danger unless the equipment was withdrawn.
Here is ISRO's Plan-B for safe landing of Chandrayaan-3's 'Vikram in case of engine, sensors fail
ISRO has developed a new plan to ensure successful landing of its 'Chandrayaan-3' Vikram lander even if its sensors or engines malfunction. Advanced de-orbiting maneuvers will align the spacecraft with the lunar surface, followed by an intricate sequence of strategic manoeuvres, to ensure a secure touchdown. ISRO's meticulous approach has contingency plans in place.
ISRO plans proper touchdown of 'Vikram' lander even if its sensors and engines fail: S Somanath
India's lunar mission, Chandrayaan-3, has been designed to ensure its lander, Vikram, can make a safe landing even if all sensors and two of its engines are not working, according to Indian Space Research Organisation Chairman S Somanath. The landing is slated for August 23. Vikram also will have the ability to land if two of its engines do not work, Somanath said, adding the biggest challenge is landing the module vertically. The Chandrayaan-2 mission failed to achieve a safe landing due to navigation-calculation errors.
FAA warns of safety hazard from overheating engine housing on Boeing Max jets during anti-icing
US regulators have warned airlines not to use an anti-icing system on Boeing 737 Max jets in dry air for more than five minutes to avoid the risk of overheating engine-housing parts, which could break away from the plane. The Federal Aviation Administration said the risk to passengers was serious enough for it to take action in 15 days, without public comment initially.
With more fuel, fail-safe measures, Chandrayaan-3 to leap towards moon on Friday
Loaded with more fuel, a slew of fail-safe measures and a bigger landing site, the Indian Space Research Organisation (ISRO) is set to make yet another attempt to land on the moon with the launch of Chandrayaan-3 on Friday. Chandrayaan-3, set for lift-off at 2:35 pm on Friday, will be a follow-up mission after the crash-landing of Chandrayaan-2 in September 2019 due to a software glitch.
Japan aborts launch of new rocket carrying missile sensor
