If you haven't noticed, shipping rates (especially international) have skyrocketed. This is due to planned increases plus ad hoc fuel surcharges, which can be $50+ alone. These are the costs for a 10 ounce, 9x12 envelope shipped to the EU. Until recently, these costs were $20 - $60. Now look at them. For the record, I do not profit on shipping; it is a pass through cost.

I ❤️ this. A non-partisan group to promote constitutional values, science and public service.

As astronauts, we didn't ask about political parties in space. The only thing we asked was what the mission required.

But now we have a new mission to preserve our democracy—which requires us to defend constitutional values.

On the authentication desk… Artemis 2 pilot, Victor Glover. A tough and very desirable autograph. 🔥🔥🔥🙌🏻

USPS rate increases coming... 🥲

For the record, I have been using USPS Ground Advantage instead of Priority Mail for several months. The delivery speed is about the same in most cases, however Ground Advantage costs significantly less than Priority Mail. I expect that trend to continue.

Something amazing is happening tomorrow and most people don't know anything about it. Artemis 2 is scheduled to launch around 6:24 pm EST Wednesday April 1. For the first time since 1972, humans are traveling to the moon. While the crew will not land on the moon, they will orbit it and return.

It's historic for many reasons, including:

☑️ First woman to the moon, Christina Koch
☑️ First African American to the moon, Victor Glover
☑️ First non-American to the moon, Canadian Jeremy Hansen
☑️ Mission Commander is an upstate NY RPI graduate, Reid Wiseman

So, take the opportunity to tune out the never-ending and pointless political BS for one day and celebrate something good! 👏

One the authentication desk…. Whoa… unauthorized Autopen machine signed Michael Collins. This Autopen did not come from NASA. 👎🏻👎🏻 Look closely… All the telltale signs of an autopen are there.
