The DASS collaboration has already secured 80 hours of JWST time for Cycle 4 (2026). The goals are:
Additionally, the European Southern Observatory’s ANDES spectrograph on the ELT (Extremely Large Telescope) will attempt to measure the planet’s rotation rate and wind speeds via high-resolution Doppler spectroscopy.
Most known exoplanets fall into two groups: rocky super-Earths (1-1.8 R🜨) and gassy sub-Neptunes (2-3.5 R🜨). The "radius valley" (Fulton gap) separates them. DASS055 C New lies directly inside this valley at 2.23 R🜨. Studying it could tell us whether planets in the radius valley have lost their atmospheres (bare rock) or retained them (mini-Neptunes). DASS055 C New clearly retains an atmosphere, supporting the "photoevaporation" model over the "core-powered mass loss" model. dass055 c new
The module requires minimum firmware version 4.2.1 on the host controller. Earlier versions will recognize the hardware but will not activate the AEC-3 or low-latency modes. A simple firmware update resolves this.
Before we focus on the "C New" designation, we must note the system’s architecture. DASS055 b was discovered in 2022 via the transit method. It is a "hot-Neptune" with a 5.2-day orbit, a radius of 2.8 Earth-radii, and an equilibrium temperature exceeding 750 K. However, a strange gap existed in the light curves—a secondary, shallower transit signal that appeared irregularly. This gap hinted at a third body.

That third body is DASS055 C.
Dassault Dass055 C New is a designation associated with a recent evolution or variant within Dassault Aviation’s classified or semi-public unmanned aerial vehicle (UAV) or advanced fighter technology demonstrator lineage. While the exact public specifications remain limited due to proprietary restrictions, the "Dass055" base code aligns with Dassault’s internal project numbering for experimental systems, and the "C New" suffix suggests a third major iteration with significant avionics, stealth, or mission system updates. a radius of 2.8 Earth-radii
The "C" likely denotes the third major development block (A → B → C). The "New" tag indicates:
