Reprogrammable Satellite Launched, is it Hackable?

Had know about this for a while.  'Reprogrammable' Satellite the European Space Agency said.   I also saw a number of the big time security wags were quick to call it 'Hackable'.    Is it?    Have they proven that or is this in the sense that anything is hackable?  The Hubble Space Telescope was just successfully reprogrammed to make it work again.   Was that a 'hack', or just a successful update of the code?  I personally like to say it had the permission of the original designers.  Could have been planned, but not necessarily so.   Can be 'completely repurposed'  they say, but I would guess they are using much of the telecom code. Its not all a hack as they say.  So lets not give the hackers the whole definition, they don't deserve it. 

Reprogrammable satellite launched

ESA / Applications / Telecommunications & Integrated Applications  in ESA

A sophisticated telecommunications satellite that can be completely repurposed while in space has launched.

Developed under an ESA Partnership Project with satellite operator Eutelsat and prime manufacturer Airbus, Eutelsat Quantum has pioneered a new generation of satellites with the European space industry.

The flexible software-defined satellite – which will be used by governments and in mobility and data markets – was launched on board an Ariane 5 on 30 July from Europe’s Spaceport in French Guiana.

It has since reached geostationary orbit some 36 000 km above Earth, where the spacecraft systems checkout was successfully completed.

Because the satellite can be reprogrammed in orbit, it can respond to changing demands during its lifetime.

Its beams can be redirected to move in almost real time to provide information to passengers on board moving ships, planes, trucks, lorries and other land-based transport. The beams also can be easily adjusted to deliver more data when demand surges.

The satellite can detect and characterize any rogue emissions, enabling it to respond dynamically to accidental interference or intentional jamming.

The satellite will remain in geostationary orbit for its 15-year lifespan, after which it will be safely placed in a graveyard orbit away from Earth to avoid becoming a risk to other satellites.

Eutelsat Quantum is a UK flagship project with most of the satellite developed and manufactured by British industry. Airbus is the prime contractor and was responsible for building the satellite’s innovative payload, while Surrey Satellite Technology Ltd manufactured the new platform. The innovative phase array antenna was developed by Airbus in Spain.  ... '

Hubble Fixed!

Consider the amount of knowledge and data involved!    Great if this comes through.   Also to the fact that such hardware and software can be remotely changed.  Also a hint to how remote maintenance can be planned for and done. 

Hubble Is Back!'   By Science  July 19, 2021

The iconic but elderly Hubble Space Telescope appears to have been resurrected again after a shutdown of more than a month following a computer glitch. Science has learned that following a switch from the operating payload control computer to a backup device over the past 24 hours, Hubble's operators have re-established communications with all the telescope's instruments and plan to return them to normal operations today.

"Hubble is back!" Tom Brown, head of the Hubble mission office, emailed to staff at the Space Telescope Science Institute at 5:56 a.m. "I am excited to watch Hubble get back to exploring the universe."
