OneWeb on Sunday announced the successful deployment of 36 satellites launched by ISRO’s commercial arm NewSpace India Limited (NSIL) from the Satish Dhawan Space Centre in Sriharikota. 

Bharti Global is the largest investor in OneWeb, a Low Earth Orbit (LEO) satellite communications company.

This latest launch by the Indian Space Research Organisation (ISRO) and NSIL marks one of the biggest commercial orders by India’s premier space organisation, and the first using the LVM3 rocket, OneWeb said in a statement.

OneWeb said it is committed to providing connectivity across the length and breadth of India by 2023.

“36 OneWeb satellites successfully launched by ISRO/ NSIL from Sriharikota,” the statement said.

On the successful deployment, OneWeb said this is the 14th launch and the second this year. This brings the total of OneWeb’s constellation to 462 satellites, representing more than 70 percent of its planned 648 Low Earth Orbit satellite fleet that will deliver high-speed, low-latency connectivity globally.

“With only four more launches to go, OneWeb remains on track to activate global coverage by 2023, while its connectivity solutions are already live in regions north of 50-degrees latitude,” the statement added.

The teaming up with NSIL and ISRO demonstrates OneWeb’s commitment to provide connectivity across the length and breadth of India by 2023, it said.

The LVM3 launch vehicle, realised with complete indigenised technology, had four consecutive successful missions, which includes the critical Chandrayaan-2 mission. The vehicle underwent several critical tests as a part of human rating for Gaganyaan programme. The cryo stage was designed to orient and re-orient in orthogonal direction to meet the customer requirements of injecting satellites precisely and with a gap to avoid collision. The vehicle was realised in a short span of time on demand driven basis to meet the user’s timeline.

Somanath S, Secretary, Department of Space and Chairman, ISRO described the event as one “very historic” to the country and the Indian space programme.

“This is the first ever commercial launch of LVM3 with a heaviest payload to LEO. The mission is very critical to meet the customer’s expectations to launch 36 satellites in 9 phases with precision,” Somanath said.

OneWeb Executive Chairman Sunil Bharti Mittal said the launch is a significant milestone for the company.

“This new phase of our launch programme from India brings us a step closer to not only enhancing our global coverage but also delivering connectivity in India and South Asia, particularly to the communities who need it most,” Mittal said.

Over the coming months, OneWeb will continue its focus on the launch programme and will also work with key distribution partners and customers to roll out connectivity solutions where its services are live.

The broadband-from-space services are being touted as the next frontier in the India’s growing communications market.

The stage is all set for some high-voltage action as big names like Jio and OneWeb gear up for a slice of the lucrative satellite-based broadband services market in India. Nelco and Telesat too have completed successful LEO demonstrations in the country for enterprise, telecom and government sectors.

The broadband-from-space segment is also being keenly watched by tech billionaire Elon Musk‘s SpaceX Starlink and Amazon‘s Project Kuiper.

NASA Astronaut Sunita Williams Refutes Health Concerns Amid ISS Mission

NASA astronaut Sunita Williams has recently addressed speculations surrounding her health condition while on the International Space Station (ISS), discarding recent claims made by media outlets regarding her wellbeing. In response to reports that suggested she appeared “gaunt” due to an extended stay on the ISS, Williams clarified her status during a video interview on November 12, explaining that her weight has remained unchanged since her arrival in orbit.

Routine Exercise and Physical Adaptations

Williams, who commands Expedition 72 aboard the ISS, responded to health concerns publicly, indicating that any changes in her physical appearance are the result of rigorous exercise routines rather than health deterioration. Like all astronauts on extended missions, she has been following an intense workout regimen designed to counteract the muscle and bone density loss commonly associated with prolonged microgravity exposure. Williams stated that her routine includes running on a treadmill, riding an exercise bike and lifting weights. It is a form of exercise that has led to increased muscle mass, particularly in her thighs and glutes, while her overall weight remains consistent.

NASA’s Statement on Crew Health

NASA had previously denied the reports, emphasising that Williams and her fellow crew members, including NASA astronaut Butch Wilmore, are in good health. Williams and Wilmore, who arrived at the ISS on June 6 aboard Boeing’s Starliner capsule, were initially scheduled for a ten-day mission under the Crew Flight Test programme. Technical issues with Starliner’s thrusters led NASA to extend their stay on the ISS until early 2025, when they are expected to return with SpaceX’s Crew-9 mission astronauts.

Current ISS Crew Status

The current ISS team, led by Williams, includes three NASA astronauts and three Russian cosmonauts, all working collaboratively despite recent media scrutiny. Williams assured viewers that her health and morale remain robust as the crew carries out essential research and maintenance tasks on the orbiting laboratory showing NASA’s confidence in their well-being during extended missions.

Math reveals secrets to gaining height on a half-pipe

A recent study reveals how skateboarders can use mathematical insights to increase their speed and height on half-pipes. Florian Kogelbauer, a mathematician from ETH Zurich, and his research team have examined how specific movements impact a skateboarder’s performance on U-shaped ramps. By alternating between crouching and standing in certain areas, skaters can generate extra momentum, leading to higher jumps and faster speeds. This research, published in Physical Review Research, could lead to more efficient techniques for skaters aiming to improve their skills.

Modelling Momentum on Half-Pipes

The research was published in American Physical Society Journal. The technique of “pumping,” or alternating between crouching and standing, is essential for building speed on half-pipes. Kogelbauer’s team created a model to show how the body’s centre of mass affects movement on a ramp, much like the mechanics of a swing. In their calculations, they found that crouching while moving downhill and standing while moving uphill helps skaters gain height more effectively. This rhythm, the team suggests, could help skaters reach higher elevations on the ramp in fewer motions.

Testing the Theory with Real Skaters

To test the model’s validity, researchers observed two skateboarders as they navigated a half-pipe. They were asked to reach a specific height as quickly as possible. Video analysis revealed that the more experienced skater naturally followed the model’s suggested pattern, reaching the target height with fewer motions. The less experienced skater, who did not follow the pattern as precisely, required more time to reach the same height. This contrast suggests that experienced skaters intuitively apply these principles for better performance.

Broader Applications Beyond Skateboarding

According to Sorina Lupu, an engineer at the California Institute of Technology, this simplified model may also have applications in robotics. By demonstrating how minimal adjustments in body position can impact speed and height, this study offers insights that could make robotic movement more efficient. For engineers, this research indicates that straightforward models of human movement could be used to enhance robotic performance, providing an alternative to complex machine-learning models often used in robotics.

Global Fossil CO2 Emissions Hit Record in 2024

Global carbon emissions from fossil fuel combustion have reached an unprecedented peak in 2024, with the Global Carbon Project reporting a projected 37.4 billion tonnes of fossil CO2 emissions, a 0.8% increase from 2023. The report underscores an urgent call for emissions reduction as the world’s annual output of CO2 from fossil fuels and land-use changes collectively approaches 41.6 billion tonnes. Despite increased efforts to mitigate climate impacts, there are no clear signs of a peak in global fossil CO2 emissions, heightening the risk of surpassing critical climate thresholds.

Sector-Specific Emissions and Regional Insights

As per a report by University of Exeter, emissions from fossil fuels, including coal, oil, and gas, are anticipated to rise in 2024, accounting for 41 percent, 32 percent, and 21 percent of fossil CO2 emissions, respectively. Coal emissions are expected to increase by 0.2 percent, oil by 0.9 percent, and natural gas by 2.4 percent. On a regional level, China, responsible for 32 percent of global emissions, is projected to see a slight increase of 0.2 percent, while emissions in the United States are expected to fall by 0.6 percent.

The European Union’s emissions are forecasted to decrease by 3.8 percent, whereas India, contributing 8 percent of global emissions, is projected to experience a 4.6 percent rise. Emissions from aviation and shipping sectors are also set to increase by 7.8 percent this year, though they remain below pre-pandemic levels.

Carbon Budget and Climate Warnings

According to Professor Pierre Friedlingstein from the University of Exeter, who led the study, the absence of a peak in fossil CO2 emissions further reduces the remaining carbon budget needed to keep warming below the Paris Agreement’s 1.5-degree Celsius target. At the current emission rate, a 50 percent probability exists of surpassing this threshold within the next six years. Meanwhile, Professor Corinne Le Quéré of the University of East Anglia acknowledged ongoing efforts in renewable energy deployment and reduced deforestation but stressed that substantial emissions reductions are still essential.

Urgency for Accelerated Action

The report emphasises that while some nations demonstrate progress in emissions reduction, these efforts have not been sufficient to reverse the overall global trend. Dr Glen Peters from the CICERO Center for International Climate Research noted that global climate action remains “a collective challenge,” with gradual declines in emissions in certain regions counterbalanced by increases elsewhere.
