ISRO Kicks Off 2024 with XPoSat Mission Launch: A Glimpse into India’s Space Exploration Agenda

In a resounding start to the new year, the Indian Space Research Organisation (ISRO) is set to launch its first X-Ray Polarimeter Satellite, XPoSat, on January 1, 2024. The mission, scheduled to lift off at 9:10 am, will mark a significant leap in India’s space exploration capabilities.

Understanding ISRO’s XPoSat Mission

While existing space-based observatories provide valuable data, deciphering the exact nature of light emitted by celestial bodies remains a challenge for astronomers. ISRO’s XPoSat mission, spanning five years, aims to measure the orientation of vibration in light waves, enhancing our understanding of the radiation mechanisms and geometry of celestial sources.

The mission, designed to capture the degree and angle of polarization, introduces two critical dimensions to astronomical comprehension, as stated by ISRO.

Payloads Unveiled

The XPoSat spacecraft carries two scientific payloads in its low Earth orbit:

1. POLIX (Polarimeter Instrument in X-rays): This primary payload measures the degree and angle of polarization in the medium X-ray energy range of 8-30 keV, originating from astronomical sources.
2. XSPECT (X-ray Spectroscopy and Timing): This payload provides spectroscopic information in the energy range of 0.8-15 keV. Together, these payloads allow the XPoSat mission to simultaneously study temporal, spectral, and polarization features of bright X-ray sources.

The capability to observe these features aids in comprehending the emission mechanisms of various astronomical sources, including black holes, neutron stars, active galactic nuclei, and pulsar wind nebulae.

Busy January for ISRO

ISRO’s January agenda is not limited to XPoSat; the space agency has an action-packed month ahead:

1. Aditya L1 Solar Probe: Within the first week of January, ISRO is set to initiate the insertion of its Aditya L1 solar probe into its halo orbit, targeting January 6, 2024.
2. INSAT-3DS Meteorological Satellites: Around January 12, ISRO is gearing up for the launch of the INSAT-3DS meteorological satellites aboard its Geosynchronous Launch Vehicle (GSLV-F14). This mission will deploy satellites for the India Meteorological Department (IMD) as part of its climate observatory satellite series.

As ISRO embarks on these ambitious missions, the Indian space exploration landscape promises exciting advancements in 2024.
