This is a write-up for Udacity VR Nanodegree.

Google Expeditions is a free VR app to take VR tours or explore items in detail, either by a single user by themselves, or led through the experience by another user, also known as the guide.

I checked Google Expeditions on my iPhone Xs Max, and the experience was worth the time, although the app was a slight disappointment. I'll deal with the good parts first.

I took the expedition to the ISS, which showed me some things that I didn't know, like that the sometimes they just stack a service capsule full of trash and let it burn in the atmosphere or that astronauts (kosmonauts?) are allowed a kilogram of personal items [1]. By the way, I'd pack my iPhone and a Kindle, former for games and latter for reading books. I can recommend the experience for anyone not familiar to the ISS.

Then the bad parts. The experience did not seem to work so well with the Udacity Cardboard kit (or Knox V2, as the app thought it was). It was hard to read the text using VR, and I actually needed to complete the assignment using the fullscreen view, as the VR caused some real problems for me. As said, I couldn't make out the text and on top of that, I started to feel slightly nauseaus, probably because of the disparity in the view that caused the "cross-eyed" feeling for the text and center view, which also made it hard to read the text and see the items.

I'm not sure whether it is a bug or not, but the expedition text panels have questions, probably directed at students taking the expedition, and the answers are right there after the questions; no interaction is needed to show the answers. This reduced the fun in answering the questions, as it was hard not to get spoiled by the answers. Also, the questions looked like they were intended to be answered after looking around in the scenes, so the placement before the info panels was odd. Maybe an issue in the full-screen view? I was not using the software as a guide, but a regular user.

Anyways, it was nice to be introduced to this tool.

[1]	Actually, the expedition said two pounds, but I would surmise the International Space Station would use SI-units. [2]

[2]	NASA uses both imperial and metric on the ISS, who'da thunk?
