Cady Coleman won't be the only mom spending this year's Mother's Day away from her child and family, but she will be higher up than any other.
Coleman is a NASA astronaut who's been living 220 miles (350 km) above the planet on the International Space Station since December 2010. And, she's the only mom in space for Mother's Day (her five crewmates are all men). [Video: Cady Coleman Plays the Flute in Space]
Coleman and her husband Josh have a 10-year-old son.
"I miss them so much and I appreciate them," Coleman told the CBS television show The Talk, speaking recently from space. "It’s a lot of work for them for me to be gone. I'm just hoping that while I'm up here the things that I'll be doing end up being worth it, and I really think they will be."
A mom in space
While Cady Coleman is the only mother in space at the moment, she isn't the first. Many spaceflyers are parents; the first mom to fly to orbit was NASA astronaut Anna Fisher, who flew on the space shuttle Discovery's STS-51A mission in 1984. [Top 12 Warrior Moms in History]
Coleman is a retired colonel in the U.S. Air Force, and has a Ph.D. in polymer science and engineering. This trip to the International Space Station is her third mission to space, following two stints on the space shuttle Columbia in 1995 and 1999. Coleman is scheduled to return to Earth on May 23 on a Russian Soyuz spacecraft landing in Kazakhstan.
But even when Coleman has both feet on the ground, staying close to her family is never easy.
"My husband lives in Massachusetts, I live in Texas, and I spent the last three years getting ready for the space station, spending about a third of my time in Russia, some in Japan, some in Europe," Coleman said during an educational event for the Women's Academy of Excellence in New York in March. "So I'm already a long-distance marriage person. I think if you have a challenging situation, you just have to figure out what's good for you and not worry about whether other people might think that it's different or not as good. For my husband and I and our son I think it works really great."
Keeping in touch
Coleman admitted that being diligent about communication is the key to staying connected with the people she loves.
"I can call on the phone from here every night," she said. "Certainly I've talked to them, I think every day but three days that I've been here. We do thing like read stories from space, my son and I, and I try to make sure that we talk about all the important things that husbands and wives need to talk about."
Coleman even brought up a stuffed "Hobbes" tiger from the comic strip Calvin and Hobbes, which she carries around the International Space Station to help her son get into the space spirit.
"I bring Hobbes with me to do experiments and I take pictures and send them down to the ground so he understands what I'm doing every day," Coleman said on The Talk.
Coleman is one of six astronauts living on the space station right now. Her crewmate, Italian astronaut Paolo Nespoli of the European Space Agency, will be having a more somber Mother's Day after receiving the news that his mother died on Monday (May 2).
The astronauts, along with Mission Control on the ground, all took a moment of silence to honor her Wednesday (May 4) following her funeral.
"We are remembering her by looking at the beautiful view from our cupola of our planet," Nespoli said then. "We are sure she has the same view from where she is now."
