Realme C71 surfaces in benchmark and certifications
Realme is working on the low-end C71 to succeed the C61 launched last summer. The C71 has been spotted in the Geekbench online database with the model number RMX5303. It's powered by the Unisoc T7250 SoC, formerly known as the Unisoc T615. This is a 4G-only chip, so don't expect the C71 to bring 5G to the table. Then again, the C61 didn't have it either. The C71 has 6GB of RAM, which its predecessor also offered. It will run Android 15 when it launches, with Realme UI on top. The C71 has also been certified for sale in Malaysia by SIRIM, which confirms its aforementioned model number. A previous certification revealed its 45W wired charging support. Unfortunately, no other specs are known at this time. Overall, we expect it to be a minor upgrade over the C61 while playing in the same pricing ballpark. We'll let you know when we find out more about it. Realme C61 Via

What is the PSLV?
At 5.59 am on May 18, the Indian Space Research Organisation (ISRO) launched a PSLV rocket in its XL configuration. It was carrying a satellite called EOS-09, which it planned to deposit into a sun-synchronous polar orbit around the earth. The mission was designated C61. But a few minutes after liftoff, the rocket suffered a problem in its third stage and the PSLV-C61 mission ended in a failure. The PSLV is a four-stage rocket. Each stage is defined by a set of engines that often fire together. Once they are done, the rocket jettisons that stage so that the remaining stages have less mass to lift. PSLV's first stage engine burns hydroxyl-terminated polybutadiene-bound (HTPB) propellant to generate a peak thrust of 4.8 MN. (In its XL configuration, six strap-on boosters augment the first stage.) The second stage is powered by a Vikas engine, which uses unsymmetrical dimethylhydrazine as fuel and nitrogen tetroxide as oxidiser to develop a thrust of 0.8 MN. The third stage is back to using HTPB as fuel whereas the fourth burns a combination of monomethylhydrazine and mixed oxides of nitrogen in two engines. After the failure of PSLV-C61 became clear, ISRO chairman V. Narayanan said the chamber pressure in the casing that contained the third-stage motor fell during the flight, leading to the unfortunate outcome. ISRO will assess the reasons for the loss of pressure in the coming days and subsequently reattempt the mission to launch (another copy of) EOS-09.

PSLV-C61 launch: ISRO chief Narayanan seeks blessings at Tirumala shrine
Indian Space Research Organisation (ISRO) chairman V. Narayanan on Friday (May 16, 2025) offered prayers at the Lord Venkateswara temple, seeking blessings for the successful launch of the Polar Satellite Launch Vehicle (PSLV)-C61/EOS-09 mission, a remote sensing satellite mission. The launch is scheduled for May 18, 2025, at 5.59 a.m. from the Satish Dhawan Space Centre in Sriharikota. During the VIP darshan in the early hours of Friday (May 16, 2025), Mr. Narayanan participated in the ritual and placed a miniature model of PSLV-C61 at the deity's feet, seeking blessings for the mission's success and safety. Vedic scholars offered blessings at the Ranganayakula Mandapam, while temple officials presented Tirtha Prasadam (holy water) and honoured Mr. Narayanan with a silk shawl. "This 101st mission with PSLV-C61 will mark a major milestone for ISRO, showcasing India's all-weather earth observation capabilities and reinforcing the country's commitment to space-based solutions," Mr. Narayanan told reporters. The mission will place the Earth Observation Satellite into a Sun-Synchronous Polar Orbit (SSPO), a unique type of polar orbit where the satellite maintains a consistent alignment with the Sun. PSLV-C61 marks the 63rd flight of the Polar Satellite Launch Vehicle and the 27th using the PSLV-XL configuration. This mission continues the PSLV's record of delivering reliable performance across a wide range of payloads and orbits, according to the ISRO website. EOS-09 is designed to deliver consistent and reliable remote sensing data for a range of operational applications across various sectors, as stated by ISRO.
