A couple of Hewlett Packard's waiters in the International Space Station in August 2017 have not yet returned to Earth, after three months.
Together they compose Spaceborne Computer, a supercomputer-powered Linux system.
They sent them as they sent them to a small specialized treatment in persistent space.
After 530 days, they are still working.
Their return flight was postponed indefinitely after a Russian rocket in October 2018.
HPE senior Container Architect Adrian Kasbergen said that in June 2019 a space is on a flight but "they have not got a ticket right away".
Nasa and Elon Musk's X space are being operated to make it "computer-ready" for the first flight of Mars around 2030.
At present, 20-year machine is returned to the ISS system for land data processing, but it has a duration of 30 minutes to travel in every way.
It is not possible to send data to Earth from Mars, while the planet is millions of kilometers away.
The original ISS's three computers cost $ 8 million and it's been built for 10 years, Mr. Kasbergen told BBC News.
"Our servers have spent billions of dollars," added the 2019 Mobile World Congress (MWC) conference in Barcelona, showing HP's ISS Destiny Module replica model.
The Spaceborne Computer is currently embedded in the real thing, Mr. Kasbergen said.
Some servers needed moderate modifications. Their air-cooling system would not work in space.
Kasbergen stated that there was no anticipation of its supply problems, as well as the solidarity unit that supports the main hard drive.
But the devices should be forced to investigate on the ground to find out what happened.
