Artemis II put humans near the Moon for the first time in 50 years. Unlike Apollo, this time @NASA isn't going alone.​
​
The signal to industry is clear: build the infrastructure for a permanent lunar presence.​
​
With the announcement of our intent to acquire @Astrobotic Technology, Voyager will have capability at every infrastructure layer needed to put Americans on the lunar surface and keep them there.​

Welcoming Operation Period to our 2027 spaceflight manifest. This will be the first spaceflight ever dedicated to studying menstruation in microgravity, investigating how space travel affects menstrual physiology, with implications for astronaut health and reproductive medicine on Earth. This is what inclusive-by-design research looks like → https://t.co/orze0lpiEf

We are excited to be part of the growing momentum for lunar transportation initiatives in Japan! 🇯🇵🌕

The JAL Group’s newly announced “ARGO PROJECT” reflects increasing interest in expanding access to the Moon across industries. Together with yesterday’s announcement of a Payload Services Agreement for ispace’s next lunar landing mission—currently scheduled for 2028—which will deliver cultural payloads intended to help preserve and pass on humanity’s stories and values to future generations, it’s another step toward building a broader cislunar economy.
