The video of the spacecraft’s ascent from the water has been posted online and shows its craft appearing to land on a rock.
The video was uploaded to the website of the Irish Space Agency, which has launched a number of unmanned satellites over the past few years.
It shows the rocket, with a number printed on the side, and a small number of people around it.
It then pans down towards a sea.
The craft was reportedly carrying three small payloads, including a camera and an optical telescope.
The Irish Space agency says the launch was to test a range of systems, including “spacecraft-based communications and weather sensing”.
It says the agency hopes to use the launch to test some of the satellite-based technologies it has been working on.
A spokesperson for the agency said: “This is a test flight, a demonstration of the capabilities of our systems and their interoperability with other space technologies.”
It is a successful demonstration of what our payload can do and the capabilities it will provide.
“The video also shows a second stage being launched and then a second landing.
The footage was uploaded on Thursday by the agency’s website.
It has since been removed.
The launch is not the first time the agency has used unmanned spacecraft in space.
The organisation has launched several unmanned satellites since 2009, but this is the first to launch a space craft from a ship.
