Fairly valued shares in the aerospace sector

Which stocks in the space sector do you think are currently fairly valued/undervalued? (Blade suppliers are also welcome.) Space has risen sharply in recent months. As I see a lot of long-term potential in the sector, I am currently considering where it would be best to invest. $ASTS (+11,07%) and $RKLB (+3,52%) had been on my watchlist for some time, but unfortunately I missed the opportunity to get in. They have already gone too far for me to buy them for the first time. I find the removal of space debris an exciting topic, which has not yet been the focus of so much attention (e.g. the disposal of space debris). $186A (+10,17%) ).
