On this day July 20 in 1976, the Viking 1 lander was the first spacecraft to land on Mars. I was 12 years old and carefully collected every last bit of news and blurry images I could glean from our local newspapers. I was still only dreaming of being a scientist, some day.

@hootalex@mastodon.social this really kiki'd my bouba

I've settled on this version of NGC7496 as the prettiest way to combine JWST and HST. I think this has a "natural" look to it. Best used as simply as eye candy. #phangs https://flic.kr/p/2nyVKv5

" the science performance of #JWST is better than expected. The optics are better aligned, the point spread function is sharper, and the optical performance is more time-stable. The fine guidance system points several times more accurately and precisely than required. The mirrors are cleaner..."

"better sensitivity ... by tens of percent... JWST will
go deeper faster than expected... enough propellant onboard to last at least 20 years."

"The report — Characterization of JWST Science Performance from Commissioning
— is now available; it summarizes the actual science performance of JWST as known on 12 July 2022, and how the actual performance differs from pre-launch expectations. The report quantitatively describes the performance of the spacecraft, telescope, science instruments, and ground system, as well as the overall observatory performance."

Big day for space science! From grand telescope views that #UnfoldTheUniverse, to extreme closeups of #SamplingMars, with rock cores barely the size of a pinky finger. I’ve now collected my 10th rock sample, seen here in the late afternoon Martian sun.
