Watch: Rocket tasked with launching humans to the Moon explodes during testing
The 156-foot motor ignited at 12:25 PM MDT, burning over 1.4 million pounds of propellant while generating more than 4 million pounds of thrust.WATCH DM-1 TEST EXPLOSION Approximately 130 seconds into the test, slow-motion footage captured debris exiting the nozzle followed by "energetic liberation" of the entire nozzle assembly. The failure manifested as an abrupt brightening of the exhaust plume before the nozzle's violent disintegration.Despite the anomaly, the motor achieved its primary objective of demonstrating full-scale ballistic performance under ambient conditions (60F), with 763 data channels recording critical metrics.Designed for NASA's future SLS Block 2 rockets, the BOLE motor represents a significant evolution from current boosters:Composite casings replace steel, reducing massUpgraded HTPB propellant replaces PBAN formulationElectronic thrust vector control eliminates hydraulic systemsLarger nozzle (4.4m diameter vs. 3.9m) enhances performanceadvertisementThese innovations aimed to increase specific impulse by 3.9% and payload capacity by 5 metric tons for lunar missions.The test motor featured carbon-fiber casings with lightning-protection copper wiring, though flight versions would be painted white.As the first of two planned development tests, the anomaly provides crucial data for refining the BOLE design. Engineers will analyse insulation performance, ablative materials, and thrust vector behaviour recorded during the test.However, the program faces uncertainty due to proposed NASA budget cuts threatening SLS Block 2 development.The BOLE boosters—destined for Artemis IX in the 2030s—depend on congressional budget negotiations reversing administration cuts to maintain viability beyond Artemis V missions.- EndsMust Watch

IMD to buy two Isro satellites to help improve weather forecast
New Delhi: The India Meteorological Department (IMD) plans to ask the Indian Space Research Organisation (Isro) to build and launch two-fourth generation INSAT series satellites, helping improve the accuracy of its weather forecasting. These new satellites will replace IMD's two third-generation INSAT satellites by 2028-29 and at cost of ₹ 1,800 crore, said IMD director general Mrutyunjay Mohapatra in an interview. The upgraded satellites will give a better resolution of images and be equipped with state-of-the-art sensors for lightning forecasting, said Mohapatra. As many as 162 people were killed by lightning strikes in March and April. Mohapatra said, "In remote areas like oceans, hills, the Himalayas and polar regions, one cannot take observations by putting up the instruments. So, here the department goes for the remote sensing instruments like radars and satellites. 'Radars have limitations because a radar can cover only up to 500 kilometers at any particular place and you cannot put radar in the sea or hill peaks where you do not have any communication system or roads or water. So therefore, a satellite becomes very handy though its accuracy is less as compared to the ground truth and radars.' IMD has been using satellite technology extensively for weather monitoring and forecasting. This started with the use of photographs from Television Infrared Observation Satellites (TIROS-1) launched by the US in 1960. The two satellites currently used by IMD have a one-kilometer in visible range and 4 km infrared range. 'Then we have cascaded these two satellites so that every 15 minutes you get an image. The satellite is geostationary. Apart from this there are other sensors in the satellite which provide other information like say winds and humidity, water vapour you can say. So, these information's we get it from our own satellites,' IMD also gets data from European, Japanese and Korean satellites. According to him, there is a cooperation among the countries that is called coordinated group of meteorological satellites. However, there are still gaps in detecting small-scale weather events, such as cloudbursts, thunderstorms, and lightning due to a lack of high-resolution data, products, and satellite-based tools. "Considering this, Isro would be developing INSAT-4 series with better sensors and resolution," said Mohapatra. The assimilation of satellite data in the models has improved the accuracy in short to medium range forecasting by about 20% to 30%, according to IMD.

Asteroid 2025 MV89 to Pass Near Earth on July 4
NASA says a small space rock named Asteroid 2025 MV89 will pass close to Earth on July 4, 2025, at 9:09 PM IST. It is about 120 feet wide, the size of a big airplane. How Fast and How Close? The asteroid is moving very fast — at 31,204 km per hour. It will pass Earth from a distance of 1,960,000 kilometers, which is about 5 times farther than the Moon. That is close for space, but still very safe. Is It Dangerous? No. NASA says it is not dangerous. It is too small and too far to be a threat. Big and very close asteroids are called 'Potentially Hazardous,' but this one is not. Why Does NASA Watch Asteroids? NASA watches space rocks using strong telescopes like Pan-STARRS, Catalina, and NEOWISE. These tools help find and track asteroids. NASA is also making a new tool called NEO Surveyor to find more space rocks early. Final Point Asteroid 2025 MV89 will pass safely. But it reminds us that watching space is important. NASA helps keep Earth safe by tracking these rocks early.

Ancient Earth kept boiling for five million years. We now know what happened
Researchers believe they've found the missing piece of the puzzle — and it's rooted in the soil. (Photo: Nasa) CO₂ levels remained sky-high, and so did global temperatures The lessons from 250 million years ago feel eerily relevant Once again, the planet may be approaching a tipping point A new study has shed light on one of Earth's most mysterious climate disasters â€' revealing that the planet remained trapped in extreme heat for millions of years after a mass extinction, largely because the plants didn't grow back fast enough. The event in question is the Permian–Triassic Mass Extinction, also known as the 'Great Dying,' which occurred around 252 million years ago and wiped out nearly 90% of life on Earth. Scientists have long linked this catastrophe to massive volcanic eruptions in Siberia that released huge amounts of greenhouse gases, causing runaway global warming. But here's the puzzling part: the extreme heat didn't subside when the eruptions ended. It lingered for five million years. Now, researchers believe they've found the missing piece of the puzzle â€' and it's rooted in the soil. Using fossil records and climate modeling, scientists reconstructed how plant life changed across the globe during and after the extinction. What they discovered was striking: a massive collapse of land vegetation, especially in tropical areas, led to very low carbon absorption by plants. Without enough greenery to pull carbon dioxide out of the air and store it in the ground, CO levels remained sky-high, and so did global temperatures. The study, published in Nature, shows how important plants are in balancing the Earth's climate. The collapse of ecosystems didn't just affect life on land â€' it created a dangerous feedback loop: fewer plants meant more CO in the air, which meant more heat, which made it even harder for plants to recover. 'This ancient climate crisis carries a clear warning,' say scientists. 'When ecosystems collapse, the climate doesn't just bounce back.' As the modern world faces rapid deforestation and rising carbon emissions, the lessons from 250 million years ago feel eerily relevant. Once again, the planet may be approaching a tipping point â€' and what happened in the past could happen again if natural systems that trap carbon are allowed to fail.
