20 years ago today (2003/5/9), "Hayabusa" was launched from the Uchinoura Space Center on the M-V-5 rocket. At the time, we had no idea of the turbulent operation that would follow, and the Hayabusa2 mission that would come next! We were just excited to face this new challenge.

This is an easy to understand video about the initial sample analysis of asteroid Ryugu. Please take a look!

It’s been just over two years since @haya2e_jaxa returned to Earth and delivered home a sample from #asteroid #Ryugu. Results from the initial analysis have begun to come in, so what have we found out so far about this intriguing asteroid, and hints about our own planet?

[Research] Observations by Hayabusa2 suggested that the entirety of asteroid Ryugu had experienced intense heat, but sample analysis found a composition of hydrated minerals. Research suggests space weathering dehydrated the asteroid top layer #RyuguWOW 🔗 isas.jaxa.jp/en/topics/0032

The top of the Hayabusa2 website has changed to show the image for the Extended Mission! The background picture shows an imaginary view during the fly-by exploration of asteroid 2001 CC21 in 2026. Hayabusa2 must still orbit around the Sun many times, but we're on our way!

The deadline to send a message to Hayabusa2 for our Million Campaign 2♯ was due today, but as it will be a while before we can actually send the messages to the spacecraft, we have extended the deadline until January 10 (noon JST) next year!

Three years ago today (February 22, 2019) was the first touchdown of Hayabusa2! We remember the extremely tense operation. The sample collected at that time is now being examined by our initial analysis team. We are excited about what we will find!
