What are some of the impacts of increased solar activity on satellites in low Earth orbit?
  • a)
    It decreases atmospheric drag, allowing satellites to maintain their orbit
  • b)
    It can cause satellites to lose power and malfunction
  • c)
    It leads to expansion of the outer atmosphere and increased atmospheric drag
  • d)
    It enhances communication signals for satellite operators
Correct answer is option 'C'. Can you explain this answer?

What are some of the impacts of increased solar activity on satellites...
Increased solar activity causes the outer atmosphere to expand due to extra energy absorption. This expansion significantly increases atmospheric drag on satellites operating below 1,000 km, which can alter their orbits and pull them closer to Earth's surface. This phenomenon poses challenges for satellite operations as it can result in premature satellite disintegration or the need for costly adjustments. An additional fact is that the International Space Station and Starlink satellites actively use thrusters to counteract these effects.

Directions:Read the following passage and answer the question.When we hear the name SPACE, only one organization comes to mind: the Indian Space Research Organization (ISRO). The Indian Space Research Organization (ISRO), located in Bengaluru, is the countrys first space agency. ISRO was founded in 1969 with the goal of developing and utilizing space technology for national development while also conducting planetary exploration and space science research. The space research operations began in India in the early 1960s, at a time when satellite applications were still in the experimental stages in the United States. Dr. Vikram Sarabhai, the founding father of Indias space programme, rapidly recognized the benefits of space technologies after the live transmission of the Tokyo Olympic Games across the Pacific by the American satellite Syncom-3 demonstrated the power of communication satellites. The ISRO has launched various spacecrafts like the Chandrayaan, AstroSat, Microsat, GSAT etc. The Government of India has also approved a regional spaceborne navigation system, which will consist of seven satellites. Out of these, four of them will be placed in geosynchronous inclined orbit of 29° relative to the equatorial plane. Such an arrangement would mean all seven satellites would have continuous radio visibility with Indian control stations.Q. Name the spacecraft that has been successfully sent into the space to probe into the planets in the solar system.

Directions: Read the passage carefully and answer the questions that follow.The world’s first wooden satellite, LignoSat, was launched by Japanese scientists on Tuesday to understand the feasibility of timber in space. Kyoto University and homebuilder Sumitomo Forestry jointly developed the wooden satellite, LignoSat, and sent it to the International Space Station (ISS) on a SpaceX mission. The satellite will be positioned approximately 400 kilometres above Earth. The mini-satellite was launched to test the viability of a renewable material in future space habitation and exploration. An astronaut and professor from Kyoto University, Takao Doi, envisions timber as a sustainable resource supporting long-term human settlement in space. While explaining the sustainability of timber in space, Doi said, "With timber, a material we can produce ourselves, we can build houses, live, and work in space indefinitely."LignoSat is inspired by wooden aircraftThe team of scientists crafted LignoSat from honoki wood, inspired by early wooden aircraft. The wood used is a Japanese magnolia species traditionally used for sword sheaths. The decision came after the 10-month ISS study confirming the Honokis resilience in space. The wooden aircraft are made without screws or glue reflecting traditional craftsmanship. The Dois team is planning for an ambitious 50-year strategy to send timber structures on the moon and mars. The spacecraft is developed with Nasa-certified wooden satellite validating wood as a space-suited material.Space temp changes drasticallyThe spacecraft will revolve around Earth for six months and it will measure how well the wood withstands the harsh space environment. The temperatures in the space change dramatically between -100 degrees and 100 degrees Celsius testing the durability of wood in extreme conditions. During its tenure in space, the woods ability to protect semiconductor components from cosmic radiation will also be analysed helping future data centre designs for space.The metal satellites leave aluminium oxide during re-entry, while this is not the case with wooden satellites which produce minimal pollution and result in a low environmental footprint. According to Doi, the success of wooden alternatives might result “in the ban of metal satellites” in future.The team is likely to promote wooden satellites to companies such as SpaceX if LignoSat performs as expected. The satellite might be revolutionising space exploration with eco-friendly materials. As per Kenji Kariya of Sumitomo Forestry, the timber industry will also benefit from the latest innovation.Material And Measure Of LignoSat SatelliteLignoSat is a 4 inches cube-sized satellite that weighs around 2 pounds, prepared with japanese techniques.According to the Japan Times, Magnolia wood was used as it has the strength and workability after space exposure tests that were conducted on cherry, birch and magnolia wood chips.The wooden satellites are less harmful to the environment post-decommissioning.Takao Doi said, “With timber, a material we can produce by ourselves, we will be able to build houses, live and work in space forever”.[Excerpt from Business Standard "Japan launches worlds first wooden satellite, LignoSat, into space " Dated 11/11/24]What is the main purpose of the LignoSat mission?
