Looking at those massive impact craters and thinking how Jezero is tiny by comparison. The energy releases during those impacts must have been huge.

andrealuck.bsky.social•66 days ago

Indeed the impactor that created the whole Argyre Basin (1500 km wide) is estimated to have been around 200 km in diameter according to Wikipedia 😅

Poor Mars certainly took some big punches.

martian-observer.art•66 days ago

So, anyway, how's it going up there in Scottishland, Andrea?

andrealuck.bsky.social•66 days ago

Going well! It’s still quite warm here. If only I were off tomorrow… 🙃

Wbu?

martian-observer.art•66 days ago

Ok, thanks, looking forward to getting my social housing flat soon (and proper broadband). Otherwise impatiently waiting for the days to lengthen 😅

skyfog.bsky.social•66 days ago

I’m impressed Viking 1 had such a good resolution already!

andrealuck.bsky.social•66 days ago

Indeed! It was an amazing mission orbiter + lander 🚀🚀

One of the best limb images I’ve seen of the Martian atmosphere.

andrealuck.bsky.social•65 days ago

Yeah that limb is something :)

If only oxygen were heavier.

andrealuck.bsky.social•65 days ago

I think oxygen makes up only about 0.13% of that sparse atmosphere 🥶

decemberjazz.bsky.social•65 days ago

That's about right, but there are two other ways to acquire O²: melting glacier ice acquires the Martian air from bubbles. But the most efficient process is to hydrolize the melted ice (water) to separate oxygen to breath and hydrogen to burn, as fuel and heat.
