ISRO PSLV-C56 mission successful
GS Paper - 3 (Space Technology)
India space agency, ISRO, on 30 July 2023 successfully launched its proven PSLV rocket carrying seven Singaporean satellites from Satish Dhawan Space Centre, Sriharikota. After lift-off, the primary satellite got separated and it was followed by six other co-passenger satellites, which were deployed into the intended orbits sequentially.
The primary payload
The primary payload carried by ISRO's trusted workhorse Polar Satellite Launch Vehicle is the DS-SAR Radar Imaging Earth Observation satellite, which has been developed under a partnership between DSTA (representing the Government of Singapore) and ST Engineering, Singapore.
The 360-kg satellite, upon deployment at an altitude of 535 km into a Near-equatorial Orbit (NEO), would be used to support the satellite imagery requirements of various agencies within the Government of Singapore.
ST Engineering would use the satellite for multi-modal and higher responsiveness imagery and geospatial services for their commercial customers.
The satellite carries a Synthetic Aperture Radar (SAR) payload developed by Israel Aerospace Industries.
The payload allows DS-SAR to provide for all-weather day-and-night coverage and it is capable of imaging at 1-metre resolution.
The co-passenger satellites are:
VELOX-AM, a 23 kg technology demonstration microsatellite
ARCADE Atmospheric Coupling and Dynamics Explorer (ARCADE), an experimental satellite
SCOOB-II, a 3U nanosatellite flying a technology demonstrator payload
NULloN by NuSpace, an advanced 3U nanosatellite enabling seamless Internet of Things connectivity in both urban and remote locations
Galassia-2, a 3U nanosatellite that would be orbiting at low earth orbit
ORB-12 STRIDER, a satellite developed under an international collaboration.
About Launch Vehicle
This mission is the 58th flight of PSLV and using the 17th vehicle with Core Alone Configuration.
A Core Alone version of the rocket means the vehicle would not use solid strap-on motors on its sides in the first stage as compared to other variants like PSLV-XL, QL, and DL which use six, four, or two boosters, respectively.
PSLV has earned its title as the 'Workhorse of ISRO' through consistently delivering various satellites into low earth orbits.
This is the second campaign to be undertaken by ISRO after the much-awaited Chandrayaan-3 mission which was launched on 14 July 2023 from the second launch pad, at Satish Dhawan Space Centre.

Supreme Court restores party symbol for Ladakh
GS Paper - 2 (Polity)
The Supreme Court on 6 September 2023 restored to the National Conference, its party symbol – the plough – after the Ladakh administration refused to allot the symbol to the party’s candidates for the upcoming election to the Ladakh Autonomous Hill Development Council (LAHDC) in Kargil.
How did the matter of the symbol for NC candidates reach the courts?
With the announcement of the LAHDC polls for Kargil, the election commissioner for the UT of Ladakh refused to allot the symbol of the plough to the NC.
In its arguments against reserving the plough symbol for the NC, the Ladakh administration said that no state party, including the NC, is a recognised party in Ladakh, and that the NC could therefore not claim its plough symbol in the UT.
However, the NC challenged this decision in the High Court of J&K and Ladakh and the courts ruled in their favour.
The NC and Congress have a seat-sharing agreement for the upcoming election to 26 seats in the Hill Council. Polls for the council were slated for 10 September 2023 however the 6 September 2023 order by the Supreme Court is likely to push the election further.
What is the LAHDC?
The Ladakh Autonomous Hill Development Councils were constituted under the Ladakh Autonomous Hill Development Councils Act, 1997.
For effective governance in the districts comprising Ladakh – Leh and Kargil – two councils were constituted in 1995 (LAHDC, Leh) and 2003 (LAHDC, Kargil). The law was deemed to come into force from June 1995.
What are the powers of the LAHDC?
Powers to both councils include drafting development plans for the region, formulation of budgets for both districts, implementation of movement schemes, promotion of language and culture, public health, education, local road transport and its development among other concerns.
Small-scale industries, non-conventional energy and tourism also form part of the 28 subjects under the LAHDC’s ambit in governance in the Ladakh region.
The Hill Councils also have the authority to levy and collect taxes and other fees in their jurisdiction.
