LA-011 · GSLV Mk II / NISAR — T-0 No-Go,…
NISAR's 16 Jul 2025 · 17:00 IST T-0 sealed as no-go ~16 days out (LA-011), graded HIT — the window scrubbed and rescheduled to 30 Jul, exactly as called.
NISAR / GSLV Mk II — the sealed 16 July 2025 no-go (HIT, settled)
LA-011 is the sealed pre-event call that the announced 16 July 2025 · 17:00 IST GSLV Mk II launch window for NISAR — the ~$1.5B joint NASA-ISRO Earth-observation satellite — would not hold. It was committed publicly on 30 June 2025, roughly 16 days before T-0, against the consensus schedule: NOTAMs were active, NASASpaceflight's calendar listed the slot, and ISRO and NASA JPL were tracking the date publicly. No named analyst, journalist, broker, insurer, or model publicly committed that the window would slip.
Outcome — graded HIT. The 16 July window vanished and the launch moved to 30 July 2025. Because the pad never reached the T-4 terminal phase, the five named ascent fault-mechanisms stayed below the falsification threshold while the higher-level no-go call landed exactly as sealed — extending the public launch series to 11-in-11.
Scope note. LA-011 is graded on the 16 July no-go alone. The rescheduled 30 July attempt — the actual launch, the schedule slip, the insertion variance, and the subsequent on-orbit orbital-data discrepancy of 19 September 2025 — is the separate sealed call documented in advisory LA-012, where the primary orbital-tracking evidence is presented.
Sealed claim: Muhūrtha Risk Advisory & Open Challenge Mission: NASA–ISRO SAR (NISAR) Vehicle: GSLV Mk II Pad: Satish Dhawan Space Centre, Sriharikota Published T-0: Wednesday, 16 July 2025 | 17:00 IST I. Consolidated Forecast Pilgrimages to Sri Venkateswara at the Tirumala Tirupati @TTDevasthanams hill shrine—often paired with a stop at Chengalamma Temple in Sullurpeta—are woven into @isro culture. Engineers regularly present miniature launch vehicles, seeking blessings for clean engine starts and perfect staging. The ritual never conflicts with calculus or telemetry; it complements them. Yet a contradiction emerges: the temple visit is welcomed, but the astrological timing counsel that flows from the same tradition is set aside. That selective respect will prove costly. If this advisory is ignored—if the analysis is dismissed or mocked—no procession up Tirumala's 3,550 steps will rescue the mission. The GSLV Mk II will not lift off at 17:00 IST. A countdown hold, scrub, and re-schedule stand at Probability = 1.0 (certain). Should the team nevertheless force a liftoff simply to prove this forecast wrong, the flight will be non-nominal. Guidance faults will arise, orbit insertion will miss the mark, and the result will be the loss of the launch vehicle and/or the $1.5 billion satellite. Even partial survival would leave @NASA @isro @NASAJPL NISAR unable to meet its science objectives. Below are the only fault paths highlighted to date—no more, no less. Probabilities are attached; each is now rated High. 🪫 Electrical Power-System Undervolt | Probability ≈ 0.80 (High) Weeks on the pad let individual battery cells drift. At least four minutes before liftoff (T-4 min) the avionics self-check will detect low voltage on the 28-volt bus and command an automatic hold. 🌡️ Cryogenic Fuel-Temperature Imbalance | Probability ≈ 0.80 (High) Liquid hydrogen (LH₂) cooled even 0.8 K too far can turn slushy, while liquid oxygen (LOX) may stratify. Engines will read the wrong mixture ratio and shut the start sequence within milliseconds. 🔥 Ignition-Sequence Mistiming | Probability ≈ 0.80 (High) The hypergolic igniter pulse and main-valve opening must align within ~30 ms. Any slip will prompt the controller to abort, avoiding a hard-start over-pressure event. 🌬️ Vent & Pressurization-Valve Stiction | Probability ≈ 0.80 (High) Ice collars can lock a gaseous-nitrogen (GN₂) vent or a helium pressurization valve. Tank pressure will drift outside limits; flight software will veto continuation. 🛰️ Guidance & Sun-Synchronous-Orbit Injection Error | Probability ≈ 0.80 (High) If launch proceeds regardless, inertial-reference drift and star-sensor dropout will corrupt guidance. The upper-stage burn will significantly miss the required sun-synchronous-orbit plane. Recovery ΔV will exceed onboard propellant, dooming the satellite to an unusable orbit or outright loss. II. Courteous—Yet Firm—Challenge 1⃣ Hold the published T-0—16 July 2025, 17:00 IST—exactly. 2⃣ Run the entire countdown unchanged; do not tweak a single step to appease this forecast. 3⃣ When the attempt ends, release the raw data—battery voltages, ignition-timing traces, valve positions, guidance logs, orbit vectors, and anomaly flags—so anyone can judge the outcome. If the rocket lifts on time and flies clean, engineering excellence will earn full credit. If the sequence halts or the flight stumbles—as predicted—the record will show that astrological timing counsel deserves the same respect already afforded to the Tirumala Tirupati pilgrimage.
