Rocket Launch Failure: Australia's Long-Awaited Orbital Attempt Crashes just 14 Seconds into Flight
The private Australian company, Gilmour Space Technologies, made history on Tuesday, July 29, with the launch of their first domestically made rocket, the Eris-1. The launch, which occurred at 8:35 a.m. local time (6:35 p.m. ET) from Bowen Orbital Spaceport in coastal Queensland, marked Australia's first attempted orbital flight in almost 54 years.
However, the journey was not without its challenges. The Eris-1 rocket, designed to launch 660 pounds (300 kilograms) of material into low Earth orbit, faced a setback shortly after liftoff. A sequential loss of thrust in its first-stage engines, due to probable oxidizer flow problems in its hybrid engine design, caused the vehicle to stall, wobble sideways, and ultimately fall back to Earth near the launch pad.
Despite the crash, which occurred 14 seconds after takeoff, there were no adverse environmental impacts, and nobody was hurt. Adam Gilmour, co-founder and CEO of Gilmour Space, described the launch as a "huge step forward" for the Eris rocket program.
The exact cause of the engine shutdowns is currently under investigation, but it is suspected that an issue with the oxidizer flow contributed to these failures. The Eris rockets, which stand at around 82 feet (25 meters) tall, use an unusual hybrid design combining solid fuel and liquid oxidizer (hydrogen peroxide). Their engines are throttleable, allowing for variable thrust, unlike traditional solid-fuel rockets.
The primary payloads for the Eris rockets will likely be small communications satellites, which are also being developed by Gilmour Space. The company remains optimistic about the future of the Eris program, considering the 14-second flight of the Eris-1 rocket a major success.
The launch was initially scheduled for March but was postponed due to adverse weather conditions caused by Cyclone Alfred. In mid-May, the launch was scrapped again due to a piece of the payload popping off the rocket on the launch pad. The exact date for the next Eris mission launch is currently unknown.
Despite the crash, Gilmour Space representatives described the event as a "big step" and an "awesome result." The Eris-1 rocket's failure during its maiden orbital flight is historically common, with most maiden private rocket launches failing to clear the launch pad. However, the fact that the Eris-1 managed to get off the pad is a testament to the progress being made in Australia's space industry.

[1] The setback in the Eris-1 rocket's first launch can be seen as a stepping stone in the development of science and technology, as investigations into the oxidizer flow problems may lead to improvements in the design of hybrid engines for space-and-astronomy vehicles.
[2] Media outlets around the world covered the historic event, with some expressing optimism about the future of Australia's space industry given Gilmour Space's resilience in the face of challenges.
[3] With the Eris-1 losses likely to be minimal, given the wreckage is contained within the Bowen Orbital Spaceport, the world now eagerly awaits the next launch of the Eris rocket that could potentially place small communications satellites into low Earth orbit, further enhancing technology in both space-and-astronomy and media communications.
