Lead: A distant blast that threatens a local launch
An explosion 92 million miles away — a powerful solar flare and associated coronal mass ejection (CME) from the Sun — could force operators to hold or scrub New Glenn launches, experts say. While no launch has been officially canceled, space‑weather alerts routinely prompt launch providers such as Blue Origin to reassess range safety, communications links and radiation risk to payload electronics and crews.
What a solar “explosion” means for rockets
Solar flares and CMEs are energetic events on the Sun that emit X‑rays, extreme ultraviolet light and streams of charged particles. The Sun sits roughly 93 million miles from Earth on average (about 92 million miles at certain orbital positions), so the effects are effectively instantaneous for photons and take anywhere from 15 hours to a few days for a CME to arrive depending on speed. National agencies including NOAA’s Space Weather Prediction Center (SWPC), NASA and the U.S. Space Force maintain monitoring assets such as DSCOVR, ACE and the Solar Dynamics Observatory to provide warnings.
For rockets like Blue Origin’s New Glenn — a heavy‑lift orbital vehicle powered by BE‑4 methane/oxygen engines and designed for launch from Cape Canaveral’s LC‑36 — space weather can be a showstopper. HF radio blackouts, degraded GPS and tracking accuracy, increased single‑event latchup risk to avionics, and enhanced atmospheric drag on low‑Earth orbit injections are all reasons range safety officials or launch providers may delay a mission.
Background on New Glenn and operational stakes
New Glenn is Blue Origin’s two‑stage orbital launcher intended to be partially reusable, competing in the same commercial launch market as SpaceX’s Falcon Heavy and Starship family. The program has faced schedule slips since Blue Origin first announced the rocket in 2017. Each scrub or delay compounds schedule pressure: launch manifest congestion at Cape Canaveral, contractual windows for payload customers, and launch insurance premiums all rise when environmental risks threaten a flight.
Why launches get delayed
Launch licensing and range clearance involve the FAA, the U.S. Space Force’s range operators, and the launch provider. When SWPC issues a G‑level geomagnetic storm warning or an R‑level radio‑blackout alert, range operators can limit launches to protect public safety and the integrity of tracking/telemetry. For example, intense solar particle events can raise the radiation dose rate for avionics, increasing the probability of single‑event effects that may cause a mission‑critical failure midflight.
Expert perspectives and industry reaction
Space‑weather specialists regularly advise the industry that the frequency of significant events rises toward solar maximum — the Sun’s 11‑year activity cycle. The current solar cycle has produced more frequent M‑class and occasional X‑class flares compared with a few years ago, increasing the probability of operational disruption.
Analysts in the launch industry note that while SpaceX and other providers face the same environment, large fleets and flexible schedules can mitigate some effects. A spokesperson for an industry analyst firm said that space‑weather delays are “manageable but costly,” adding that companies with multiple launch pads and fast‑turnaround operations are better buffered.
Satellite operators have also warned that launches to certain orbital regimes are more sensitive to ionospheric disturbance. GNSS (GPS) integrity can degrade during geomagnetic storms, complicating precision guidance during ascent. Payload owners frequently require risk assessments for charged‑particle environments and may insist on mission postponement if thresholds are exceeded.
Implications for Blue Origin and the broader market
Operational pauses driven by solar activity highlight a non‑technical risk that nonetheless has real commercial impact. For Blue Origin, a delayed New Glenn maiden flight or postponed commercial missions would mean additional scrutiny from customers and insurers at a critical time for the company’s credibility in the heavy‑lift market.
For the broader commercial space sector, recurring solar activity underscores the need for hardened avionics, improved real‑time space‑weather forecasting, and more robust range procedures. Investors and enterprise customers will increasingly factor in space‑weather resiliency when selecting launch providers.
Conclusion: Preparing for the Sun’s next move
While the Sun’s explosive events originate some 92–93 million miles away, their impacts are immediately local for launch operators. As solar activity accelerates toward and through the next maximum, flight schedules for New Glenn and competing rockets will need to account for an unpredictable but well‑monitored hazard. Strengthened forecasting, hardened systems and flexible manifest planning are the industry’s main tools to blunt the Sun’s influence on the increasingly busy commercial launch cadence.
