The UK launched a satellite back in 1971 called Prospero. Atop a Black Arrow launch vehicle it went up from Woomera, Australia.

When Saas gives you updates and good quality support it's worth it. When they're charging you over and over again to fix bugs in their program that should have corrected before launch, it's not worth it.

This is almost certainly a misunderstanding on the part of the writer. MRIs have emergency vents for Quenches, and while the helium does "Boil off" it's at a very low rate. Most systems also include recondensers to recapture evaporating helium. It's worth noting that most places don't include capture and chill systems because the system requires a lot of space, the system costs a small fortune and you spend more powering the system than you save in recapturing the helium. Also, worth noting, helium isn't toxic but can kill if it displaces the air in a room. As such all places that worth with He should have O2 sensors. A slow leak is safe-ish as the helium rises and just goes away.

Background: I'm on the technical team for a research unit that has an MRI machine of its own and access to another. Plus I do Helium refills for an MEG facility. This does not ring true. An MRI is going to have something like 500L of liquid helium in it. It doesn't cool by "Boiling it off". In fact a high boil-off rate is a bad thing. The unit will have a chiller to keep the temperature of the helium down and probably a recondenser to reduce loss. If the unit quenched during install then all the helium will have boiled off. A lot more than 120L. Also the vents are certified so that *All* the helium that boils off goes up and out safely. Add to that all these facilities have O2 alarm systems, this must have been a very small, slow leak over the course of months. Any leaking helium will have risen straight up to the ceiling and spread out, maybe working its way up into cracks and passing to above floors at a massively reduced concentration. At the levels we're talking about here, if the helium were the problem then we'd be seeing a spate of iPhone failures at children's parties from the helium in the balloons.
