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.

WHO holds first traditional medicine summit
GS Paper - 3 (Health and Diseases)
The World Health Organization opened its first summit on traditional medicine with the group saying it was seeking to collect evidence and data to allow for the safe use of such treatments. Traditional medicines are a "first port of call for millions of people worldwide", the UN health agency said.
More about the summit
The two-day WHO Traditional Medicine Global Summit takes place alongside a meeting of G20 health ministers in the Indian city of Gandhinagar.
The first global traditional summit, co-hosted by the World Health Organization (WHO) and the Ministry of Ayush.
This summit is designed to foster political commitment and evidence-based action in the field of traditional medicine.
As a vital healthcare source for millions worldwide, traditional medicine will be closely examined and evaluated as a formidable force in addressing health and well-being needs.
With a wide array of engagement groups, working groups, and meetings, this event aims to represent the interests of the Global South countries within the G20 framework.
The theme of "One Earth, One Family, One Future" embodies India's philosophy of Vasudhaiva Kutumbakam.
More about traditional medicine
The UN health agency defines traditional medicine as the knowledge, skills and practices used over time to maintain health and prevent, diagnose and treat physical and mental illness.
But many traditional treatments have no proven scientific value and conservationists say the industry drives a rampant trade in endangered animals -- including tigers, rhinos and pangolins -- threatening the existence of entire species.
Use of homemade remedies soared during the Covid-19 pandemic, including a green herbal drink based on Artemisia that was promoted by Madagascar's president as a cure.
The plant has a proven efficacy in malaria treatment, but its use to combat Covid was widely scorned by many doctors.
In China, traditional medicine has a distinguished history, but top European medical bodies have previously demanded it be subject to the same regulatory oversight as conventional medical methods.
Flashback
Of the WHO's 194 member states, 170 acknowledged their use of traditional and complementary medicine since 2018, but only 124 reported having laws or regulations for the use of herbal medicines -- while only half had a national policy on such methods and medicines.
About 40 percent of approved pharmaceutical products currently in use derive from a "natural product basis", according to the WHO, which cited "landmark drugs" that derive from traditional medicine, including aspirin, drawing on formulations using willow tree bark.

Russia’s Luna-25 crashes
GS Paper - 3 (Space Technology)
Russia’s Moon mission ended in failure after its spacecraft Luna-25 spun out of control and crashed into the moon, Russian space agency Roscosmos said on 20 August 2023.
What happened to Luna-25?
Luna-25 was supposed to land on the Moon on 21 August 2023, days ahead of India’s Chandrayaan-3. Its intended landing site was close to Chandrayaan-3’s, near the lunar south pole.
The crash was confirmed a day after Roscosmos reported an “abnormal situation” which its specialists were analysing.
The space agency had said on 19 August 2023 that it had lost contact with the aircraft as it was shunted into pre-landing orbit.
On 19 August 2023, in accordance with the flight program of the Luna-25 spacecraft, an impulse was provided for the formation of its pre-landing elliptical orbit.
Communication with the Luna-25 spacecraft was interrupted. The measures taken on 19 and 20 August 2023 to search for the device and get into contact with it did not produce any results. According to the results of the preliminary analysis, due to the deviation of the actual parameters of the impulse from the calculated ones, the device switched to an off-design orbit and ceased to exist as a result of a collision with the lunar surface, Roscosmos said.
The space agency also said, A specially formed interdepartmental commission will deal with the issues of clarifying the reasons for the loss of the Moon [mission].
What was the Luna-25 mission?
Although launched on 10 August 2023, almost a month after Chandrayaan-3’s launch on 14 July, Luna-25 rode on a powerful rocket to reach the lunar orbit in just six days.
It was supposed to land on the lunar South Pole before Chandrayaan-3, and its success would have made Russia the first country to do so. Luna-25’s mission life was for one year, and its lift-off mass was 1,750 kg.
It did not carry a rover, but had eight payloads mainly to study the soil composition, dust particles in the polar exosphere, and most importantly detect surface water on the moon.
Significance
The failure of Luna-25 underlines how tricky soft-landings on the Moon are, and echoes India’s heartbreak of 2019.
Since 1976, there has been just one country, China, which has been successful in getting its spacecraft to soft land on the moon.
It has done that twice, with Chang’e 3 and Chang’e 4. All other attempts in the last ten years, by India, Israel, Japan and now Russia, have remained unsuccessful.
If Chandrayaan-3 is able to land successfully, India would become just the fourth country in the world, after the United States, the erstwhile Soviet Union and China, to have landed a spacecraft on moon, and the first-ever to land close to the lunar south pole.
