| Summary | A Japanese commercial solid-fuel small launcher that has failed on all three flight attempts through March 2026, putting its commercial viability in serious question. | Relativity Space's Falcon-9-class successor to Terran 1, partially 3D-printed, with 13 Aeon R methalox engines on a reusable first stage; second stage and fairing expendable. | India's most reliable and frequently flown launch vehicle, operational since 1994. Set a world record in Feb 2017 by deploying 104 satellites in a single flight (Cartosat-2D + 103 microsats). Launched Chandrayaan-1 (2008), Mars Orbiter Mission (2013), and Aditya-L1 (2023). The dual C61/C62 failure streak raised concerns about aging solid motor design. The vehicle is on a return-to-flight campaign (not retired): PSLV-C63 (TDS-01 technology demonstrator), with strengthened third-stage/PS3 checks following the expert-committee (FAC) review, is targeted for late June / early July 2026. |
