NASA responds to curious learners!

  • While watching the Expedition 59 spacewalk,  Mrs. Hartwig's 1st Graders were curious and asking lots of questions.  

    They even got their question answered live on the air from NASA!  
     
    Hartwig's First Graders watched Flight Engineers Nick Hague and Anne McClain venture outside the International Space Station’s Quest airlock to replace nickel-hydrogen batteries with newer, more powerful lithium-ion batteries.
