ITSy

This refers to SpaceX smaller and more economical version of its ITS.

Elon Musk is going to give details about this latest design on the 29th September 2017 at the IAC 2017 conference in Adelaide, Australia

What is know so far :

As with ITS the goal is to be fully reusable and refueled in space.

The main reasons for this smaller scale ITS is development cost and also given the current political climate towards NASA's to target the Moon that the ITSy will be good at achieving.

The new rocket will have a 9 meter diameter, enabling it to be assembled at SpaceX Hawthorne LA and be transported by road.

It will land back to base onto a location pin allowing booster landing without legs, The F9 landing on the 24th August 2017 of the Falcon 9 was a test flight to prove the landing accuracy required, it landed on the droneship 'Just Read the Instructions' being ocean going made this even more impressive.

• • Touchdown: Vertical Velocity (m/s): -1.47

  • Lateral Velocity (m/s): -0.15

  • Tilt (deg): 0.40 ​

  • Lateral position: 0.7m from target center

This being well within the 2m accuracy required.

Propulsion

ITSy looking likely to use Raptor engine technology but using fewer engines than the original ITS design due to its smaller diameter.
