# What Launches Were Scheduled the Week of Sept 1–5, 2026?

Six orbital missions were scheduled across four countries during the week of September 1–5, 2026 — a week headlined by Galactic Energy's Pallas-1 medium-lift debut from Jiuquan, [Rocket Lab USA](https://orbital-intel.com/companies/rocket-lab)'s 15th Electron mission of the year, and what would mark [SpaceX](https://orbital-intel.com/companies/spacex)'s 102nd Falcon 9 flight of 2026. Launch sites in China, New Zealand, the United States, India, and Norway were all on the manifest. The most commercially significant story of the week was Pallas-1's first flight: a 49-meter, kerolox, partially reusable medium-lift rocket capable of delivering 5,000 kg to a 400 km [low Earth orbit (LEO)](https://orbital-intel.com/glossary/leo), directly challenging the sub-5-tonne payload class that currently underpins dedicated small-to-medium commercial launch in the Asia-Pacific region.

## Pallas-1 Makes Its Debut: China's Reusable Medium-Lift Field Gets More Crowded

The week's most consequential first flight came from Galactic Energy, a Chinese private launch company already operating its Gushenxing-1 (Ceres-1) small-satellite launcher. Pallas-1 — also designated Zhishenxing-1 — lifted off Tuesday, September 1, at 02:00 UTC from the Pallas-1 Launch Pad at the Jiuquan Satellite Launch Center on a southward trajectory optimized for sun-synchronous orbit.

The vehicle's specs are worth examining carefully. At over 49 meters tall and more than three meters in diameter, Pallas-1 is a two-stage rocket powered by seven company-developed Welkin engines in its first stage, burning kerosene and liquid oxygen — the same propellant combination as Falcon 9. Rated payload capacity: 5,000 kg to a 400 km circular orbit, or 3,000 kg to a 700 km SSO.

That last figure matters for the commercial satellite market. A 3,000 kg SSO capacity covers the bulk of Earth observation and remote sensing payloads that currently compete for rideshare slots or dedicated Falcon 9 missions. Galactic Energy is explicitly targeting that tier.

The demonstration flight did not appear to include a landing attempt, though Pallas-1 is designed for booster recovery using grid fins and landing legs — hardware choices that mirror Falcon 9's architecture. The company is already developing Pallas-1B, a three-core heavy-lift variant designed to lift up to 17,500 kg to LEO, comparable in concept to Falcon Heavy.

**Skeptical take:** Pallas-1's heritage in reusability remains unproven at this stage. A debut flight without a landing attempt means the reusability case rests entirely on hardware that hasn't yet demonstrated return. Chinese private launch companies have made rapid progress, but Galactic Energy still needs to close the operational reuse loop before claiming Falcon 9 parity on economics.

## Rocket Lab's Electron: 15th Mission of 2026 and On Pace to Break 20

Rocket Lab's "Owl Around The World" mission for Japanese synthetic aperture radar operator Synspective launched from Launch Complex-1 at the Mahia Peninsula in New Zealand on Tuesday, September 1, at 11:30 UTC. The target orbit: a 575 km circular orbit inclined 38 degrees to the equator — a mid-latitude plane that gives Synspective broad imaging coverage across populated regions of Asia, Europe, and the Americas.

The payload is StriX-9, the 11th SAR satellite Rocket Lab has launched for Synspective. The satellite weighs approximately 100 kg and is capable of imaging at a resolution of one to three kilometers with a swath width of 10 to 30 km. Synspective has an additional 16 flights booked with Rocket Lab through 2030, making this one of the most durable dedicated launch partnerships in the small satellite sector.

This was Electron's 15th flight of 2026. Per the source, Rocket Lab is on pace to exceed 20 missions for the full year — a cadence that, if achieved, would represent a material step in demonstrating that a dedicated small launch vehicle can sustain commercial-scale operations.

## Falcon 9 Mission 102: Starlink Shifts Fully to California

Wednesday, September 2's Starlink flight — scheduled for 07:46 UTC from Space Launch Complex 4E at Vandenberg Space Force Base — carried 27 Starlink v2 Mini satellites to a 70.01-degree inclination LEO. The booster, B1063 on its 35th mission, targeted a landing on the drone ship Of Course I Still Love You in the Pacific, marking what would be the 675th Falcon 9 recovery attempt.

B1063's career illustrates how thoroughly SpaceX has normalized high-reuse operations. The booster's manifest includes Sentinel-6A Michael Freilich, the DART planetary defense mission, Transporter 7, Iridium-9, OneWeb #19, Tranche 0B, multiple NROL missions, and 25 Starlink runs before this flight.

The broader context: per the source, SpaceX has flown its last planned Falcon 9 Starlink mission from Florida. All future Starlink v2 Mini missions are planned from Vandenberg — a logistics and range-scheduling shift that consolidates the [mega-constellation](https://orbital-intel.com/glossary/megaconstellation) replenishment cadence on the West Coast and likely frees Eastern Range capacity for other customers and vehicles.

## ISRO's GSLV Mk II Returns After a Rough 2026

India's space agency had a difficult start to the year: the January EOS-N1 PSLV-DL failure left ISRO with only one successful launch through most of the year. Thursday, September 3's GSLV Mk II F17 mission represented its second flight of 2026.

The rocket — a 49.13-meter, three-stage vehicle combining a solid core, four [hypergolic](https://orbital-intel.com/glossary/hypergolic) strap-on boosters, a hypergolic second stage, and a cryogenic liquid oxygen/liquid hydrogen upper stage — placed the 2,367 kg EOS-05 satellite (also designated GISAT-1A) into a [geostationary transfer orbit](https://orbital-intel.com/glossary/gto). Target: an eventual geostationary slot enabling EOS-05 to image the entire Indian landmass every 30 minutes at 42-meter resolution in visible and near-infrared.

EOS-05 is a direct replacement for EOS-03 (GISAT-1), lost in a GSLV Mk II launch failure in August 2021. The satellite has an explicit disaster-response application — rapid imagery of flood events, including the glacier-collapse-induced flash floods reported in the Himalayas that same week. This was the 19th overall mission of the GSLV Mk I and II series.

## Isar Aerospace's Spectrum: Second Attempt from Norway

Isar Aerospace's Spectrum small satellite launcher was scheduled for its "Onward and Upward" flight on Friday, September 4, from the Orbital Launch Pad at Andøya Rocket Range in Norway, with a 60-minute window opening at 20:00 UTC. Per the source, Spectrum's first flight last year ended in failure. Isar investigated the root cause, modified the vehicle, and targeted a January 2026 relaunch that slipped due to a pressurization valve issue.

The company's ability to reach Andøya for a second attempt is itself a meaningful data point: European sovereign small launch capacity from Norwegian soil remains a strategic priority for ESA member states and EU defense customers who need non-US launch options.
