Let's make this birthday one to remember.

74 years old (Born on April 15, 1951)

Happy Birthday, Marsha Ivins! You've soared higher than most of us ever dream—deploying satellites like the EURECA back in '92 and giving the International Space Station a stellar upgrade aboard Atlantis in 2001. Honestly, your resume makes our earthly accomplishments look downright grounded.

Here's hoping your birthday is as memorable as floating weightlessly through space (but with better cake). May you continue orbiting around happiness and success for many more years to come. After all, someone who has spent their career among stars deserves nothing less than an astronomical celebration today!

Cheers to another trip around the sun!
