Watch Neuralink’s First Brain-Chip Patient Playing Chess Using His Mind
The Indian Space Research Organisation (ISRO) successfully carried out the third hot test of its semi-cryogenic engine Power Head Test Article (PHTA) on 28 May 2025 at the ISRO Propulsion Complex (IPRC), Mahendragiri. The test is part of a series of performance evaluations aimed at validating key subsystems of the 2000 kN-class SE2000 engine that will eventually power the SC120 propulsion stage intended to replace the existing L110 liquid core stage of the LVM3 launch vehicle. ISRO began this series of performance evaluations in March 2025, focusing on critical components such as low- and high-pressure turbo-pumps, the pre-burner, the start-up system, and various control mechanisms.
The three-phased trials
According to the official ISRO press release, the PHTA has undergone two hot tests earlier, which included all systems except the thrust chamber. The first test on 28.03.2025 demonstrated the smooth ignition & bootstrap operation over a short duration of 2.5 seconds. The second hot test on 24.04.2025 demonstrated the start transient build-up and tested the start-up sequence by carrying out a hot-firing for a duration of 3.5 seconds. The third test was carried out for a duration of 3 seconds to fine-tune further & finalize the start-up sequence.
The SE2000 employs an oxidizer-rich staged combustion cycle using liquid oxygen and kerosene. It is able to deliver a chamber pressure of 180 bar and a specific impulse of 335 seconds—an upgrade over the L110 stage’s hydrazine-based propulsion.
Future Integration and Impact on Indian Launch Capability
With the subsystem validations complete, ISRO will now begin integrated engine-level trials, moving toward full operational readiness. The SC120 stage powered by SE2000 is expected to increase LVM3’s payload capacity from 4 to 5 tonnes to Geostationary Transfer Orbit (GTO) and from 8 to 10 tonnes to Low Earth Orbit (LEO).

A blue-eyed toddler buried 1,350 years ago in southern Germany was laid to rest with extraordinary wealth, including a small sword, silk-trimmed garments, silver jewellery, and even a cooked piglet, according to archaeologists. The child, dubbed the “Ice Prince” for the frozen excavation technique used, was about 18 months old at the time of death and appears to have belonged to a powerful regional family near Mattsies, Bavaria. Genetic analysis showed he had light hair and blue eyes, and anatomical studies suggest he died from an ear infection that developed into a chronic illness.
Aristocratic Bavarian Toddler Buried With Sword, Silk, and Piglet in Roman-Era Villa Tomb
As per a translated statement from Bavarian state archaeologists, the child’s tomb was found within a Roman-era villa that had later been repurposed, possibly reflecting the family’s desire for a high-status burial. The sealed stone chamber was frozen in liquid nitrogen, then excavated as a single block to preserve its immaculate contents. Radiocarbon dating puts the burial between A.D. 670 and 680; enamel isotopes point to the infant having lived and died locally.
Inside the grave, the boy was placed on a fur blanket and dressed in leather and silk — a textile linked to Byzantine trade and exceptional wealth. Silver spurs were found on his shoes, and a small sword hung from an ornate belt. A gold cross was embedded in fabric placed near the body, possibly reflecting early Christian practices, although Bavaria wasn’t fully Christianised until after Charlemagne’s rule.
The burial chamber also held nuts, apples, and a pear, suggesting ceremonial food offerings. What were once thought to be dog bones turned out to be those of a dismembered piglet, potentially cooked as part of burial rites. The inclusion of a bronze basin, comb, bowl, and silver-fitted cup further suggests an elite burial.
Renovations to the Roman villa site after the death of the lad testify to its long-term usage as a family monument. The great preservation and abundance of burial goods reflect the aristocratic origins of the child and provide uncommon understanding of early mediaeval Bavarian society.
