Astronauts were the first to timeshift

Astronauts were among the first to start timeshifting, though in the early days, they called it "sleep shifting." It helped them launch at odd hours and stay alert both on orbit and during spacewalks. Back on Earth, it helped them reduce jet lag when they traveled to Russia, Germany, and Japan for training. It is the same science-based circadian algorithm that powers Timeshifter today.

Two of them, former NASA astronauts Michael López-Alegría and Mike Massimino, know the difference it makes firsthand.

“I think what is very gratifying about this product is that it comes from a lot of the lessons we learned at NASA. Without a tool like this you are kind of guessing what you need, and I think it’s much better to use data to help you make those informed decisions. It’s great that what was out of necessity for us to keep astronauts awake while doing their job is now something that I can use when I travel when I am no longer an astronaut.” – Mike Massimino, Former NASA Astroanut, and Timeshifter investor

“When I was an active astronaut at NASA, I used the same science-based circadian algorithm as Timeshifter is deploying in their app. When on missions, it helped me prepare for launches at odd hours, and to perform at my best on orbit. On earth, it helped me to eliminate jet lag when traveling to train in time zones as disparate as the U.S., Japan and Russia.” – Michael López-Alegría, Former NASA Astroanut, Commander of Axiom’s Ax-1 mission and Timeshifter investor
