What Are Artemis II Astronauts Eating in Space? Breaking Down the Menu

Kellie Gerardi’s next chapter is ready for takeoff. 

The research astronaut welcomed her second baby, a little girl named Maxine Quinn, with husband Steven Baumruk. And just like her sister Delta Victoria, 8, baby Maxine’s name is fit for a space traveler in the making.  

“Mission Success, and Space Baby has a name,” Kellie wrote on Instagram April 6 alongside pictures of her newborn. “So grateful to officially introduce you to our sweet girl, Maxine Quinn. Welcome to the world, Max Q! You’re going to love it here.”

Baby Max’s space-inspired name refers to “the moment of peak mechanical stress on a rocket” when pressure from the surrounding air is at its highest, according to NASA

But she’s not the only member of the family with a scientific moniker. After all, Kellie and Steven’s 8-year-old is named after Delta-v, a measure of change in velocity in physics. 

After welcoming Maxine Earthside, Kellie detailed the moment she met her “Space Baby.”

“The past ~48 hours have been a blur of the best kind and yesterday was spent soaking in the fact that she’s really here,” Kellie—who has been candid about her fertility struggles—captioned an April 5 Instagram video of Maxine’s birth. “I’m forever grateful we didn’t hit the brakes too soon on this IVF journey to complete our family.” 

“I’m still in pain and am mentally, emotionally, spiritually, and physically exhausted to my core, and I’m so grateful for all of it,” she added. “I’ve been reading every single kind comment and my heart is aching in the best way from the love. Happiest Easter to all of you.”

The 37-year-old announced she was pregnant with baby Maxine in August. At the time, she detailed her cautious optimism about her pregnancy journey while detailing her anxiety after previously experiencing four miscarriages. 

"Crying in the parking lot of my IVF clinic again, but this time happy tears," she captioned an emotional video of herself getting an ultrasound. "Seeing that flicker is everything to me. We’re still far from out of the woods, but if me and this little cheerio-sized miracle can make it another few weeks together, I might finally graduate from my IVF clinic this time."

"I know I'm not out of the woods yet," Kellie, who suffers from secondary infertility, wrote in the video, "but I feel like I just finally let out a breath that I've been holding for weeks. Grow, baby, grow!"
