It's day one for me, and I just wanted to say thank you to some of the folks that help make this dream a reality. Anna, Grace, James, thank you so much from deep in my heart. Grace, happy birthday, and I know some of my friends and colleagues from SpaceX, where I used to work, were out there rooting me on and sending me messages. Thank you all for teaching me how to do the impossible. I have used that lesson time and time again.And to the guardians at the Space Force, this is the biggest domain, and your job, our job, is unbelievably big. I'm proud to serve alongside you, and also to NASA, who makes this all happen and is tasked with doing the near impossible, going to the moon, going to Mars, and pushing our boundaries where we have never gone, I am happy to be working alongside of you, using the space station as a stepping stone to those huge dreams of ours. Let's go, team. Let's do this."Menon is the first NASA astronaut of Malayali heritage to travel to space.Also Read: Meet Anil Menon, NASA astronaut who will spend 8 months aboard space station: All about the Indian-origin doctor who once served in AfghanistanMenon reached the International Space Station aboard the Roscosmos Soyuz MS-29 spacecraft alongside Russian cosmonauts Pyotr Dubrov and Anna Kikina.Who is Anil Menon?Born in Minneapolis, Minnesota, Menon is an emergency medicine physician, aerospace medicine specialist and Colonel in the United States Space Force.His father, K.P.
