I'd assume about 175 / 180; that's pretty standard for this kind of dish. Usual advice from Americans on making banana bread is to use the oldest, mushiest bananas you can, as well.
Indeed! (See pre-launch preparations at 0:02s). For this launch, we targeted 180 degrees centigrade.

The more we rely on space technology, the more vulnerable we are to cyber-attacks.

#CyberResilience matters, and ESA is prioritising it.

#WTISD
The shift from analogue to digital is exposing humanity to the promises and perils of new technologies.

... these past images are searched to see if the 'new' asteroid has in fact been lurking. If they spot it, researchers can extend the 'arc of observation' back through time and space, to project forwards a very precise path for the object.

What's an asteroid "precovery"?☄️👻

Calculating an asteroid's orbit, and so the risk it poses to Earth, requires measuring its position on multiple occasions. For newly discovered asteroids, only a few days or weeks of data are available, so just a preliminary path can be traced pic.twitter.com/BFc6BdwWtc
