ISRO successfully places seven Singaporean satellites into intended orbit
Sriharikota, (AP) (PTI): ISRO on Sunday successfully launched its proven PSLV rocket carrying seven Singaporean satellites from Satish Dhawan Space Centre here and placed them into intended orbits.
Around 23 minutes 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, ISRO said.
This ISRO mission, which comes after the much-awaited Chandrayaan-3 launch earlier this month, is being undertaken by its commercial arm NewSpace India Limited (NSIL).
ISRO Chairman S Somanath said, "The PSLV-C56 carrying seven satellites including primary satellite DS-SAR and six co-passenger satellites have been successfully placed in the right orbits."
After the 25 hour countdown that commenced on Saturday concluded, the 44.4 metre tall rocket lifted off majestically from the first launch pad at this spaceport, one minute after the prefixed time of 6.30 am, emanating thick fumes on its tail.
The lift-off time which was scheduled for 6.30 am today was later revised to 6.31 am as space debris was expected on the path of the rocket during its journey to the orbit. "Change of lift-off time occurs when space debris come in the path of rocket. That is what happened today," an ISRO official told PTI.
"This is the mission of the PSLV for NSIL and I want to congratulate the customers sponsored by Government of Singapore for having this mission on board PSLV and their continued faith in our PSLV for deploying the spacecrafts (satellites) from Singapore," Somanath said at the Mission Control Centre.
"Congratulations once again to NSIL for the Singapore satellites which have been onboard this mission and the very perfect orbit that this time we have got. But at this moment I thank all of you for watching this mission early morning this day and supporting us and congratulating us and we want to specifically tell you that we are going to come back with another PSLV mission soon in the month of August or early September" he said.
On the successful launch and separation of the satellites, ISRO posted on Twitter, "PSLV-C56/DS-SAR Mission: The mission is successfully accomplished. PSLV-C56 vehicle launched all seven satellites precisely into their intended orbits. Thanks to @NSIL_India and Singapore, for the contract."
NewSpace India Ltd Chairman and Managing Director D Radhakrishnan said, "My heartiest congratulations to team ISRO for the PSLV project across various centres for giving us such a marvelous and precise mission and I don't think the customer would have asked for anything better than what we have just seen in today's mission.
"I would say in the history of our PSLV launches, commercial launches for international customers, a single customer (Singapore government) coming to PSLV continuously four times for a dedicated launch has been a real record and that shows the kind of trust the customer has laid on the teams here. I am aware Singapore is planning many more missions in the future and they will continue to have trust on our services and the most reliable launcher, the PSLV that we have offered the service, and I am sure they will offer us many more opportunities for us to give them the best launch in the international community." he said.
In today's dedicated commercial mission, 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 1. VELOX-AM,a 23 kg technology demonstration microsatellite, 2. ARCADE Atmospheric Coupling and Dynamics Explorer (ARCADE), an experimental satellite, 3. SCOOB-II, a 3U nanosatellite flying a technology demonstrator payload, 4.
NULloN by NuSpace, an advanced 3U nanosatellite enabling seamless Internet of Things connectivity in both urban and remote locations, 5. Galassia-2, a 3U nanosatellite that would be orbiting at low earth orbit and 6. ORB-12 STRIDER, a satellite developed under an international collaboration, the Bengaluru-headquartered space agency said.
Today's mission is the 58th flight of PSLV and using the 17th vehicle with Core Alone Configuration.
According to the space agency, a Core Alone version of the rocket means the vehicle does 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, ISRO said.
This is the second campaign to be undertaken by ISRO after the much awaited Chandrayaan-3 mission which was launched on July 14 from the second launch pad at Satish Dhawan Space Centre, here. Sriharikota is located about 135 km from Chennai on the eastern coast.
Currently, the Chandrayaan-3 spacecraft is undergoing orbit raising manoeuvres. On July 25, ISRO scientists successfully performed the fifth orbit-raising manoeuvre of the Chandrayaan-3 spacecraft setting the stage for the planned August 1 journey towards the Moon after leaving the orbit of the Earth.
Today's mission follows PSLV-C55/TeLEOS-2 mission, which was successfully launched in April to serve the customers in Singapore.

High courts upheld only 8 per cent of death sentences; SC confirms none in recent years: Report
New Delhi (PTI): Highlighting that a high acquittal rate of death row convicts by the Supreme Court and high courts demonstrates a pattern of "erroneous or unjustified convictions", a study of 10 years of death penalty data has revealed that the top court did not confirm any death sentences in recent years.
The study by Square Circle Clinic, a criminal laws advocacy group with the NALSAR University of Law in Hyderabad, found that an overwhelming majority of death sentences imposed by trial courts did not withstand scrutiny at higher judicial levels. Acquittals far outnumbered confirmations at both the high courts and Supreme Court levels.
According to the report, the trial courts across India awarded 1,310 death sentences in 822 cases between 2016 and 2025. High courts considered 842 of these sentences in confirmation proceedings but upheld only 70 or 8.31 per cent.
In contrast, 258 death sentences (30.64 per cent) resulted in acquittals. The study noted that the acquittal rate at the high court level was nearly four times the confirmation rate.
Data showed that of the 70 death sentences confirmed by high courts, the Supreme Court decided 38 and did not uphold a single one. The apex court has confirmed no death sentences between 2023 and 2025.
"Wrongful or erroneous or unjustified convictions, then, are not random or freak accidents in the Indian criminal justice system. The data indicates they are a persistent and serious systemic concern," the report said.
Over the last decade, high courts adjudicated 1,085 death sentences in 647 cases, confirming only 106 (9.77 per cent). During this period, 326 persons in 191 cases, were acquitted.
The report attributed low confirmation rates to the appellate judiciary’s concerns regarding failures in due process. "This coincides with increased Supreme Court scrutiny of safeguards at the sentencing stage," the report said.
Of the 153 death sentences decided by the apex court over the last decade, the accused were acquitted in 38 cases. In 2025 alone, high courts overturned death sentences into acquittals in 22 out of 85 cases (over 25 per cent). The same year, Supreme Court acquitted accused persons in more than half of the death penalty cases it decided (10 out of 19), the report said.
The study highlighted that 364 persons who were ultimately acquitted "should not even have been convicted and unjustifiably suffered the trauma of death row". It added that such failures extend beyond adjudication and reflect serious lapses in investigation and prosecution.
The question of remedies for wrongful convictions remains pending before the Supreme Court. In September 2025, three persons acquitted by the apex court filed writ petitions seeking compensation from the state and argued that their wrongful convictions violated their fundamental right to life and liberty under Article 21 of the Constitution.
"In 2022, the Supreme Court crystallised a sentencing process in Manoj v. State of Madhya Pradesh , and mandated all courts to follow those guidelines before imposing or confirming a death sentence," the report read.
In 2025, the apex court held in Vasanta Sampat Dupare v. Union of India that death penalty sentencing hearings form part of the right to a fair trial and stressed that capital punishment can be imposed only after a constitutionally compliant sentencing process.
"However, even at the high courts whether the process mandated under Manoj is being complied with is in doubt,” the report said.
