ISRO Chairman S Somanath on Wednesday said there is not enough internal demand for the satellite launch market in India but it can be created through more work on the application of satellite technology.Addressing the India Space Congress 2024, he said big companies are willing to enter the space sector but they are concerned about the timeline for breaking even and securing orders. “When I talk to many of those industries who are willing to come and set up facilities, they are all very ready to do it. But they are asking when they are going to break even and where the orders are so that they can safely invest in this. I think this is a big question.“It is the bigger challenge of convincing investors to come in a big way in big state projects,” the leading space scientist said.At a press conference on the sidelines of the Space Congress, he said, “We need to create more internal demand. That implies internal demand is not enough. All of us are working towards that. The demand will come from the user side, from the communication segment, which, of course, includes big satellite builders.” “We would like to find orbital slots and frequencies which can be given to industry to build satellites and launchers. This is the first step towards creating internal demand. InSpace has already announced a funding plan to create a new earth observation constellation. That’s again another step towards creating internal demand.” Somanath also said although the cost of accessing space has decreased significantly globally, largely due to SpaceX, India’s rocket costs have not seen similar reductions.Reducing costs could boost small satellite launches and attract new participants in the space sector, he said.Somanath mentioned that Prime Minister Narendra Modi’s vision for Amrit Kaal includes extending human space activity beyond the Gaganyaan mission, with the goal of landing on the moon by 2040.However, he said India’s current rockets are not sufficient for round trips to the moon. Developing rockets with higher payload capacity is essential for both bringing back samples and future human missions, the ISRO chairman said.“Though GSLV MKIII (LVM3) is the biggest rocket that we have, it is not big enough. It has just enough capability to go up to the moon, but it cannot even come back. We need to develop the capability to bring samples back and then send humans to the moon and bring them back,” he said.Somanath said the development of such capabilities must also consider commercial sustainability. Space activities should support a broader ecosystem and not just focus on lunar missions, he said.The scientist said India’s industrial capacity to produce launchers needs significant enhancement and more companies must enter this field to increase production capabilities.Somanath told reporters that GSAT-20 is set to launch in mid-August onboard Falcon 9 and it has received clearance to be moved to the United States for launch.

In 1974, Gerard O'Neill, a Princeton University professor and space visionary, proposed using electromagnetic rail guns, or "mass drivers," to launch payloads from the Moon. These mass drivers, based on a coil gun design, were intended to accelerate non-magnetic objects, enabling the launch of lunar materials into space for manufacturing purposes. O'Neill, working with Henry H. Kolm and student volunteers at MIT, developed the first prototype mass driver with support from the Space Studies Institute. Over time, subsequent prototypes have refined and improved upon this concept.Today, this concept finds a practical application aboard the U.S. Navy's Gerald R. Ford nuclear aircraft carrier. The carrier employs the Electromagnetic Aircraft Launch System (EMALS), which uses electromagnetic fields to launch aircraft. Manufactured by General Atomics Electromagnetic Systems (GA-EMS), EMALS has successfully completed over 10,000 launches and landings, proving its reliability and efficiency.In a report titled "Lunar Electromagnetic Launch for Resource Exploitation to Enhance National Security and Economic Growth," General Atomics outlined a vision for applying electromagnetic launch technology to lunar resource exploitation. Authored by Robert Peterkin, the report was submitted to the Air Force Office of Scientific Research (AFOSR). It emphasizes that the Moon is rich in resources such as silicon, titanium, aluminum, and iron, and highlights the potential for using lunar water.The report proposes that a future lunar economy could use these resources to resupply, repair, and refuel spacecraft in lunar orbit more cost-effectively than transporting resources from Earth. Electromagnetic launches from the lunar surface are highlighted as more efficient than chemical rocket launches, which require fuel to be imported from Earth. By using solar energy as a power source, these launches could be more sustainable.Peterkin advocates for the U.S. government to fund the development of a lunar electromagnetic launch system, evolving from the existing EMALS technology used on the Gerald R. Ford. The goal is to achieve higher speeds at lower mass to launch pound-class payloads from the lunar surface into low lunar orbit at 3,758 miles per hour (1.68 kilometers per second). Demonstrating the ability to achieve this speed for at least 100 launches without needing to replace launcher components is crucial for proving viability.Establishing a path to a mature lunar ecosystem involves moving materials off the Moon reliably, affordably, and safely. Initially, this will depend on machinery and systems supplied from Earth. However, the ultimate aim is to create a self-sustaining ecosystem that extracts, processes, and launches lunar materials to support cislunar spacecraft and space settlements.

Three newly discovered Martian craters have been named after physicist Devendra Lal and the towns of Mursan and Hilsa, highlighting significant geological findings on Mars.Three craters recently discovered on Mars have been named in honor of the renowned cosmic ray physicist Devendra Lal and the towns of Mursan and Hilsa in northern India. This naming was approved by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature on June 5, 2023. The discovery and naming were facilitated by scientists from the Physical Research Laboratory (PRL) in Ahmedabad, India, a unit of the Department of Space of the Government of India.The craters are located in the Tharsis volcanic region of Mars, a vast plateau near the equator in the planet's western hemisphere. Tharsis is known for housing the largest volcanoes in the Solar System.Crater Details:Lal Crater: The largest of the three, Lal Crater is 65 km wide. It was named after Professor Devendra Lal, who served as the director of PRL from 1972 to 1983. The crater is significant because evidence suggests that water once moved large volumes of sediment into it, indicating that Mars was once wet and had flowing water on its surface. The subsurface of Lal Crater contains a 45-meter thick sedimentary deposit, discovered using SHARAD (Mars SHAllow RADar sounder) on NASA's Mars Reconnaissance Orbiter (MRO).Mursan and Hilsa Craters: These craters, each around 10 km wide, are located on the eastern and western rims of the Lal Crater, respectively. Named after towns in Uttar Pradesh and Bihar, India, they provide a timeline for the infilling process of the Lal Crater, suggesting that the infilling occurred in episodic events.Scientific Discovery:The discovery was made within the Mangala crater of Mars using data from SHARAD on the MRO probe. The research team included Rajiv Bharti, Isaac Smith, S. K. Mishra, N. Srivastava, and Shital Shukla. Bharti, Mishra, and Srivastava are affiliated with PRL, while Shukla is with Gujarat University and Smith is from York University in Toronto, Canada.The PRL release highlights that the entire area of Lal Crater is covered with lava but also contains geophysical evidence of other materials, including significant sedimentary deposits.

ISRO's MARBLE project features a novel coaxial rotor system designed to operate in Mars' thin atmosphere, enhancing lift and efficiency for Martian exploration.The Indian Space Research Organisation (ISRO) is advancing Martian exploration with its ambitious project, the Martian Boundary Layer Explorer (MARBLE). A key innovation in this project is the development of a novel coaxial rotor system designed to function efficiently in the thin and harsh Martian atmosphere.Challenges of Martian Atmosphere:Mars presents a unique set of challenges for rotorcraft:The atmosphere is approximately 100 times thinner than Earth’s, making lift generation difficult.The average surface temperature is around -63°C (210K), a harsh environment for traditional helicopter designs.Coaxial Rotor System:To address these challenges, ISRO is developing a coaxial rotor system. This design includes two sets of rotors, one above the other, rotating in opposite directions. The coaxial configuration provides several benefits:Increased Lift: The design allows for a smaller rotor diameter while still generating enough lift, which is crucial for the thin Martian air.Reduced Rotor Stress: By spreading lift generation across two rotors, the stress on each blade is reduced, lowering the risk of issues related to high Mach number flow.Aerodynamic Optimization: The blades are specifically crafted for Martian conditions, maximizing efficiency and thrust.Significance for Mars Exploration:The coaxial rotor system for MARBLE represents a significant milestone in ISRO’s Mars exploration efforts. This innovative design is poised to overcome the atmospheric challenges of Mars, potentially enabling future helicopters to gather essential scientific data and explore the Martian surface in greater detail than ever before.By developing this advanced technology, ISRO is positioning itself at the forefront of Martian exploration, contributing to our understanding of the Red Planet and paving the way for more sophisticated missions in the future.
