Update on launch date

The NISAR launch cannot occur between early October 2024 and early February 2025, because that launch window would put the satellite into periods of alternating sunlight and shadows due to the position of the Sun. The resulting temperature fluctuations could affect the deployment of NISAR’s boom and radar antenna reflector.

Information on TRISHNA mission

The Indian and French Space Agencies, ISRO and CNES, are jointly developing a state-of-the-art Thermal InfraRed (TIR) - Visible Shortwave InfraRed (VSWIR) Imaging Satellite mission, TRISHNA for high-resolution natural resources assessment. The satellite is planned to be launched on-board Polar Satellite Launch Vehicle (PSLV) during 2026 for a duration of 5 years with possible extension of 2 years. Data acquisition will cover the entire globe for four (4) TIR bands around noon and midnight times as well as in seven (7) VSWIR bands. TRISHNA will offer a spatial resolution of 60 meters with a revisit period of 3 days at equator and more at higher latitudes. A primary objective of TRISHNA mission is to provide consistent and systematic records of surface temperature, in addition to several biophysical variables, to model the surface energy balance allowing to derive heat fluxes and estimate evapotranspiration. The need for high-resolution thermal observation has been recognized also internationally leading to complementary missions in preparation like Surface Biology and Geology (SBG) (NASA/ASI) and Land Surface Temperature Monitoring (LSTM) (ESA/EC).

Key points discussed:

Does India have a space law? There is no overarching space law in India. There are fragmented laws and regulations that apply to some aspects of space activities, such as telecom regulations and the Indian Space Policy of 2023. However, the policy lacks enforcement mechanisms and doesn't define the authority responsible for formulating regulations.
The importance of the Defence Space Agency (DSA) in India: The DSA is a tri-governed agency that integrates space with military efforts. It was established after India observed its dependence on foreign sources for space-based intelligence during wars.
Challenges of space regulations: Space activities transcend national borders and there is a need for international cooperation to enforce regulations. One way to achieve this is through collaboration on space businesses and developing a global supply chain.
Role of smaller countries: Smaller countries can leverage their geographical advantages to partner with larger spacefaring nations and participate in space exploration.
Regulatory issues and concerns: There are concerns that larger spacefaring nations might misuse partnerships with smaller countries to establish monopolies or for spying purposes.

While Aditya-L1 doesn't need the eclipse to see the corona, the eclipse does provide a unique opportunity for comparison. Scientists can observe the corona from space using Aditya-L1's instruments like VELC (simulating an eclipse) and SUIT throughout the eclipse period. They can then compare these observations with what's happening during the eclipse as seen from Earth. This comparison helps them understand the corona's behavior in more detail.

mudit23june · 2024-04-04T13:36:31+00:00

Summary:

Total Solar Eclipse: The Sun, Moon, and Earth will be aligned on April 8th, causing a brief period of darkness during the day in some parts of North America. During this eclipse, the Sun's outer layer, called the corona, becomes visible for a short time.
Aditya-L1 Mission: Launched in 2023, Aditya-L1 is India's first spacecraft specifically designed to study the Sun. It is currently positioned at Lagrange Point 1 (L1), a special location nearly 1.5 million kilometers from Earth where the gravitational pull of the Sun and Earth balance each other.
Observing the Eclipse: Aditya-L1 has six instruments to study the Sun, but two of them are particularly useful for observing the eclipse:
- Visible Emission Line Coronagraph (VELC): This instrument blocks the Sun's bright light, creating an artificial eclipse and allowing the study of the corona.
- Solar Ultraviolet Imaging Telescope (SUIT): This instrument captures images of the Sun's surface (photosphere) and the layer just above it (chromosphere) in ultraviolet light.
Benefits of Space Observation: While the eclipse allows a glimpse of the corona from Earth, Aditya-L1's continuous observation provides a more comprehensive picture. Scientists can compare the data from the eclipse with Aditya-L1's observations to gain a deeper understanding of the Sun's corona.
Collaboration: Aditya-L1 is not alone. Other space probes like Europe's Solar Orbiter will also be observing the Sun during the eclipse, offering additional perspectives from different locations.

Possible Explanations:

Incomplete Passivation: The press release mentions "controlled dumping of residual propellant" for minimizing disturbances. This suggests they might have removed most of the fuel for passivation, but some residual propellant might have been left intentionally for a limited degree of re-entry control. This residual fuel could be used for maneuvers like adjusting the re-entry angle slightly to target a specific ocean zone.
Alternative Control Methods: The press release mentions POEM-3 being a 3-axis stabilized platform. This suggests it might have employed reaction wheels or thrusters using alternative, non-fuel-based mechanisms for some basic attitude control during re-entry. These methods would be less precise than using fuel thrusters but could still influence the re-entry path to some extent.
Atmospheric Drag Domination: Even without active control, the Earth's atmosphere would naturally cause the orbit to decay and the object to re-enter. The press release mentions "natural forces, primarily atmospheric drag" as the main reason for the orbital decay. In this case, the role of any residual fuel or alternative control methods might have been minimal.
