Comment reconnaître la face cachée de la Lune ? Des cratères à perte de vue, aucune mer lunaire, les taches sombres qui caractérisent la face visible. Sur la face visible, c’est pas qu’il y a moins de cratères, c’est que les mers les ont recouverts. Salukes #science #physique #lasciencepeuttout

Knicks look to unlock Jalen Brunson. Use Shamet as a screener to get Mitchell in action. Big key is Cleveland does not automatically switch. That does open up another side. KAT now goes to screen, reject engages Mobley who was dropped back. KAT pops and is now able to drive.
