India's Aditya-L1 solar mission spacecraft commences collecting scientific data
Bengaluru (PTI): India's Aditya-L1 solar mission spacecraft has commenced collecting scientific data to help scientists analyse particles surrounding Earth, ISRO said on Monday.
The sensors on board India's first solar observatory have begun measuring ions and electrons at distances greater than 50,000 km from Earth, ISRO announced in a post on X.
The national space agency said that the sensors on STEPS or the Supra Thermal & Energetic Particle Spectrometer instrument began measuring supra-thermal and energetic ions and electrons at distances greater than 50,000 km from Earth.
The instrument is a part of the Aditya Solar Wind Particle EXperiment (ASPEX) payload of Aditya L1.
STEPS comprises six sensors, each observing in different directions and measuring supra-thermal and energetic ions ranging from 20 keV/nucleon to 5 MeV/nucleon, in addition to electrons exceeding 1 MeV. These measurements are conducted using low and high-energy particle spectrometers.
The data collected during Earth's orbits helps scientists to analyse the behaviour of particles surrounding the Earth, especially in the presence of its magnetic field.
STEPS was activated on September 10 at a distance greater than 50,000 km from Earth. This distance is equivalent to more than eight times the Earth's radius, placing it well beyond Earth's radiation belt region.
After completing the necessary instrument health checks, data collection continued until the spacecraft had moved farther than 50,000 km from Earth.
These STEPS measurements will persist during the cruise phase of the Aditya-L1 mission as it progresses toward the Sun-Earth L1 point. They will continue once the spacecraft is positioned in its intended orbit.
Data collected around L1 would provide insights into the origin, acceleration, and anisotropy of solar wind and space weather phenomena.
STEPS was developed by the Physical Research Laboratory with support from the Space Application Centre in Ahmedabad.
Aditya-L1 was launched by ISRO on September 2.
The spacecraft carries seven different payloads to study the Sun, four of which will observe the light from the Sun and the remaining three will measure in situ parameters of the plasma and magnetic fields.
Aditya-L1 will be placed in a halo orbit around the Lagrangian Point 1 (L1), which is 1.5 million km from the Earth in the direction of the Sun. It will revolve around the Sun with the same relative position and hence can see the Sun continuously.

VHP warns of statewide stir in Karnataka against move to ease cattle transport law
Udupi (Karnataka) (PTI): The VHP on Saturday demanded the immediate withdrawal of a proposed amendment to the Karnataka Prevention of Slaughter and Preservation of Cattle Act, 2020, accusing the state government of weakening a law that has deterred illegal cattle transport.
The organisation's Go Raksha Wing, Karnataka South, has also announced district-level protests on December 8.
According to officials, the existing law mandates a bank guarantee for securing the release of vehicles seized for alleged illegal cattle transportation.
On December 4, the state Cabinet proposed an amendment enabling the release of such vehicles on an indemnity bond instead.
Addressing reporters in Udupi, VHP leader and Prantha Goraksha Pramukh Sunil K R, said the government's move amounted to "sympathy for cattle lifters" and claimed that it was part of broader actions "targeting Hindus".
He argued that the law in its current form is stringent and has played a crucial role in reducing incidents of illegal cattle transport and theft.
Under the Act, vehicles involved in offences can be surrendered and, upon conviction, permanently seized by authorities. "Diluting these provisions will embolden offenders," Sunil said.
The VHP leader warned that easing the process of vehicle release would not only encourage violators but also result in rising cruelty against cattle.
Sunil further claimed that the strict enforcement of the 2020 law had brought down cases of cattle-related offences significantly. Rolling back these provisions, he said, could reverse those gains and would lead to an increase in illegal transport.
He reiterated that the government must reconsider its decision and preserve the integrity of the existing law.
