Can ISRO’s Aditya L1 mission face any danger after NASA’s Parker Solar Probe faces most powerful CMEs?
Subject: Science and technology
Section: Space technology
Aditya L1 Mission:
- India’s first solar exploration mission aimed at studying the Sun in detail.
- Payloads: Carries seven distinct payloads.
- The latest update from ISRO indicates that the Aditya L1 Mission has successfully executed the Trans-Lagrangean Point 1 Insertion (TL1I)maneuver, positioning it on a trajectory toward the Sun-Earth L1 point.
- Aditya L1 has commenced collecting scientific data on the Sun.
- Arrival Timeline: Aditya L1 is anticipated to reach its designated L1 orbit around the Sun approximately 126 days (about 4 months) after its launch.
Understanding Coronal Mass Ejections (CMEs):
- Coronal Mass Ejections (CMEs) are massive eruptions of solar plasma and magnetic field from the Sun’s corona.
- Space Weather Impact: CMEs influence space weather, potentially causing disruptions to satellites, communication systems, navigation technology, and even power grids on Earth.
Parker Solar Probe’s CME Encounter:
- On September 5, 2022, NASA’s Parker Solar Probe encountered one of the most powerful coronal mass ejections (CMEs) ever recorded.
- This encounter was not only an impressive engineering feat but also a significant scientific discovery.
- NASA collected valuable data about the CME and its effects during this encounter.
Potential Threats to Aditya-L1 Mission:
- Aditya L1 is on a trajectory to enter a halo orbit around Lagrange Point 1 (L1).
- Lagrange Point 1 is located approximately 1.5 million kilometers (about 1 million miles) from Earth (accounting for roughly 1 percent of the Earth-Sun distance)
- Solar Storm Expectation: Aditya L1 may potentially encounter solar storms during its journey, particularly due to the expected peak in solar activity.
- Distinct Proximity: Aditya L1’s proximity to the Sun is notably different from that of NASA’s Parker Solar Probe, which orbits at a much closer distance, approximately 6.9 million kilometers (about 4.3 million miles) from the Sun’s surface.
- Parker Solar Probe’s CME Encounter: To put it in perspective, the Parker Solar Probe previously faced CMEs when it was at a distance of approximately 9.2 million kilometers(about 5.7 million miles) from the solar surface, significantly closer than Aditya L1.
