ISRO successfully carries out first rocket launch test with satellite in UP's Kushinagar; details here
The Indian Space Research Organisation (ISRO) successfully conducted a rocket launching test in Uttar Pradesh's Kushinagar on Saturday, June 14. This marks a historic moment for the state as it was the first time a payload was launched through a rocket from the state, officials informed PTI. "The rocket was launched at 5:14 PM and 33 seconds, which went up to a height of 1.1 km. After this, a small satellite (payload) came out. As soon as it fell down to 5 metres, its parachute activated and the satellite landed within 400 metres on the ground." PTI quoted ISRO scientist Abhishek Singh as saying. The test was carried out in collaboration with Thrust Tech India Limited. During rocket launch test, the spacecraft ascended 1.1 km at 5:14:33 PM before setting off the satellite, marking a complete success. It is important to note that both the satellite and the 15 kg rocket descended safely. The latest rocket launch test is in many ways different from previous tests conducted in Ahmedabad using drones, since this was the first time a satellite was directly launched using rocket in UP, proving entirely successful, ISRO scientist said. This test sets the stage for future satellite tests scheduled for October-November, where nearly und 900 youth-built satellites will be tested. Director of Thrust Tech India Vinod Kumar confirmed the company's motor test success and said, 'This event is being organised to generate interest in space technology among children across the region and the whole of India.' The space agency dropped latest update on the long-postponed Axiom-4 commercial mission to the International Space Station and in a post on X stated, 'Observations on Falcon-9 LOX leak have been resolved by @SpaceX @Axiom_Space is coordinating with @NASA on the ISS Zvezda module anomaly. The earliest possible launch date for #Ax4 is being worked out.' This upcoming space mission is notable as it includes Indian astronaut Shubhanshu Shukla among its four crew members. According to an official release by the Indian Space Research Organisation (ISRO) on Saturday, a follow-on coordination meeting was held between ISRO, Axiom Space, and SpaceX, where it was confirmed that the issue of liquid oxygen leak observed in the Falcon 9 launch vehicle was successfully resolved.

Fuel leak delays Indian astronaut's launch: The science behind using liquid oxygen
The launch of the Axiom-4 mission, which was set to carry a crew of four astronauts, including India's Group Captain Shubhanshu Shukla, to the International Space Station (ISS) was delayed hours before launch on June 10, mission was earlier delayed by a day due to bad weather at the Kennedy Space Center in Florida. Now, a new technical issue has caused a further delay -- a leak of liquid oxygen (LOX) has been found in the launch discovered the leak during a routine seven-second 'hot fire' test of the Falcon 9 rocket's booster stage, about 12 hours prior to the launch time. These tests simulate launch conditions by briefly igniting the rocket's engines to check for performance and structural integrity. During the test, a leak was detected in the propulsion bay, an area that houses critical fuel and engine components. As a precaution, SpaceX, the company which owns and operates Falcon 9, has paused the launch to repair the issue and conduct additional tests before setting a new launch DOES LOX DO IN ROCKETS?To understand what went wrong, it is important to know the role of LOX in rocket launches. Rockets need two main components to create the thrust needed to escape Earth's gravity: a fuel and an fuel provides the energy, while the oxidizer enables it to burn. On Earth, oxygen from the atmosphere acts as the oxidizer in everyday in space or even higher altitudes, where there is less or no air, rockets must carry their own source of is where LOX comes acts as the oxidizer and is combined with fuels like kerosene, liquid hydrogen, or methane in the rocket's engine. When ignited, the fuel and LOX burn together at very high temperatures and pressure, creating the powerful thrust that pushes the rocket into space. Without LOX, the fuel alone wouldn't burn in the vacuum of must be kept at an extremely cold temperature, around -183 degrees Celsius, to stay in liquid form. This makes it very sensitive and dangerous to a small leak can cause frost to form on critical parts or lead to dangerous pressure buildup. If LOX comes into contact with fuel or other materials, it can catch fire or even explode. Because of these risks, handling LOX requires very strict safety OF USING LOXLOX is used in many of the world's most powerful rockets. NASA's Saturn V, SpaceX's Falcon 9, the European Ariane series, and India's GSLV all rely on LOX as oxidizer for their the dangers of LOX leakage are not just theoretical. There have been several accidents in the past caused by problems with oxidizers. Gp Capt Shubhanshu Shukla ahead of launch with Ax-4 crew. (Photo: Axiom) One major example is from the early Soviet space July 3, 1969, the USSR's N1 rocket exploded just 23 seconds after launch. This rocket was built to compete with NASA's Saturn V and send cosmonauts to the Moon, and was powered by a combination of kerosene (RP-1) as fuel and liquid oxygen (LOX) as the oxidizer.A fault in one of the engines caused the rocket to lose thrust and fall back onto the launch pad. Upon impact, the tanks ruptured, and the two substances mixed uncontrollably. This triggered a massive explosion. At the time, it was the largest non-nuclear explosion in history.A more recent and widely known incident occurred on January 28, 1986, when NASA's Space Shuttle Challenger disintegrated just 73 seconds after liftoff, claiming the lives of all seven astronauts on board. While the immediate cause of the disaster was a failed rubber O-ring seal on the right solid rocket booster, LOX still played a critical role in the sequence of events that followed. The faulty seal allowed hot gases to escape and strike the shuttle's external fuel tank, which housed two cryogenic propellants: liquid hydrogen (LH2) in the lower section and LOX in the upper section. The escaping flame weakened the tank's structural integrity until it the LOX and hydrogen were mixed outside the tank, they ignited in a massive fireball that engulfed and destroyed the orbiter. The Challenger tragedy shocked the world and led to a suspension of NASA's shuttle program for nearly three years.A related incident of oxygen leakage threatening catastrophic failure happened in 1970 during the famous Apollo 13 mission. This was meant to be NASA's third Moon landing, but it turned into a gripping fight for survival. Apollo 13, soaring more than 300,000 kilometers from Earth, suffered an explosion in one of its oxygen tanks (though this gaseous oxygen) — the lifeline of the spacecraft. In an instant, systems collapsed, and three astronauts were left stranded in space. advertisementWhat followed was nothing short of extraordinary. Engineers on Earth and the astronauts aboard worked around the clock,improvising solutions with limited resources. Using the lunar module as a lifeboat, they pulled off a miraculous delays may seem frustrating, they are a small price to pay when human lives are at space, even a minor flaw can spiral into a disaster. By postponing the Axiom-4 launch to address the LOX leak, SpaceX and Axiom are prioritising safety over speed. A delay today prevents a catastrophe the repairs and rechecks are complete, a new date will be set, and when liftoff comes, it will still fulfil the hopes of a nation proud to see one of its own reaching for the stars. And of course, this is just the beginning for India's manned space mission.(This is an authored article by Srijan Pal Singh.

Pedro Martinez selected as education commissioner
BOSTON (WWLP) – The search for a new Bay State education commissioner continued as the commission met on Tuesday to recommend their top choice of the final three candidates. The candidates were pulled from a pool of over 40 applicants, and three ultimately made it to the final interview round–assistant superintendent of Detroit public schools and former Chicago innovation chief Jack Elsey, former deputy commissioner of school programs in the Texas school system Lily Laux (LOX), and leader of Chicago public schools Pedro Martinez. Several Board members emphasized that any of the top candidates would greatly benefit Massachusetts. Congressman Neal discusses budget cuts by Trump administration at Veterans Roundtable in Ludlow 'I regret that we don't have a tri-partheid commissionership to solve the problem, but we don't,' said Holyoke's Michael Moriarty, a board member. Ultimately, the board selected Pedro Martinez, praising his deep understanding of education data, dedication to poor and marginalized children, extensive leadership experience, and personal story as an immigrant and English Language Learner. 'I give the edge to Pedro Martinez,' said Education Secretary Patrick Tutwiler. 'There is a proven track record of success in extraordinarily unideal context.' Two board members abstained from the final vote, throwing their support behind Lily Laux, both mentioning her understand of what Massachusetts needs and focus on literacy rates. The selected commissioner is set to begin their official duties this July.
