How does Isar Aerospace fit in with other smaller rocket launchers?<p>I'd imagine they are well behind, say, RKLB, but how far are they from commercial launches?<p>Edit after some digging, some background info:<p><pre><code> Vehicle | Height | Diameter | Payload to LEO
-----------+--------+----------+----------------
Electron | 18 m | 1.8 m | 300 kg
Isar | 28 m | 2.0 m | 1000 kg
Neutron * | 43 m | 7.0 m | 13000 kg
Falcon 9 | 70 m | 3.7 m | 23000 kg
* in the works
</code></pre>
To Rocket Lab's defense, they do quite a bit more than just launching Electrons and chipping at the Neutron.
