It’s still hard for me to believe that everything in cellular #biology I learned in #highschool in the early 90’s had been discovered as little as 40 years before.
It all seemed so definitive, so orderly, all set in stone, like it was obvious it had to be known since forever, it was so elegant! Stop telling me scientists in 1952 did not know this!!
Curiosity Has Spent Three Years Trying to Reach this Spot on Mars
About three billion years ago, rushing water on Mars carried mud and boulders down a steep slope and deposited them into a vast fan-shaped debris pile. NASA's Curiosity Rover has been trying to reach a ridge overlooking the region, and it finally reached its vantage point after three years of climbing. NASA released a 360-degree view image of the region, showing the jumble of rocks strewn about by the rushing water, and now Curiosity can reach out and touch them.
Three billion years ago, amid one of the last wet periods on Mars, powerful debris flows carried mud and boulders down the side of a hulking mountain. Now, after three attempts, NASA’s Curiosity Mars rover has reached the ridge, capturing the formation in a 360-degree panoramic mosaic.
In my conversations for @Flipboard's "The Art of #curation" #podcast, I kept hearing the word #curiosity when I asked curators what made them successful.
Scott Shigeoka has poured his life into understanding this quality, which is the subject of his upcoming book “Seek: How Curiosity Can Transform Your Life and Change the World.”

#Curiosity continues its time travel into Greek antiquity examining targets with names like Antikythera, Delphi, Mycenae and Zagori. It'll pay special attention to dusting off the Antikythera mechanism, er, I mean bedrock, before exiting the Greek quad and entering the Bishop quad (California), where new rock names will be taken from.
The rover continues its adventures in Greek name territory, encountering features called Hydra, Dodoni, Thassos, Rouskio, Antiparos, and Milos. Four of them are named after Greek islands in the Aegean.
Want to know how to operate a rover on another planet? #Curiosity team's reports are the best available resource for that, explaining both plans and their execution.
And all that while learning new rock/place names, currently originating from Greece, like Ολυμπία, Αρτεμίσιο, and Παλαιοχώρι.
Cet été, j'ai eu la chance de visiter le JPL, ce centre de la NASA où sont conçues, assemblées et testées la plupart des sondes et rovers américains qui explorent le Système solaire. Un récit de ma visite pour vous emmener dans cet endroit mythique. 1/37 @nasajpl@NASA#NASA#JPL
J'ai pu tenir en main un exemplaire d'ingénierie de la perceuse de Curiosity. C'est lourd ! On voit le tube par lequel le matériau prélevé va dans SAM ou CheMin. La dernière photo montre des tests de forage. Un trou fait le diamètre de l'auriculaire. 13/37 #Curiosity#marsrover#CuriosityRover#NASA#JPL
Depuis quelques années, la perceuse de Curiosity ne fonctionne plus aussi bien et la poussière prélevée ne peut plus passer par le tube. Pour la distribuer aux labos SAM et CheMin, le rover met sa perceuse au-dessus des orifices et la secoue. 14/37 #Curiosity#marsrover#CuriosityRover#NASA#JPL
Nous sommes ensuite entrés dans le garage du "Scarecrow", un robot constitué uniquement du système de mobilité des rovers (voir 4e image, crédit NASA library), sous la bâche en Mylar.
Au fond, de nombreuses roues pour les tests. Celles de Curiosity sont plus sales ! 17/37 #Curiosity#CuriosityRover#NASA#JPL#MarsRover
