The Nancy Grace Roman Space Telescopes Instrucment Carrier has arrived at NASA Goddard

The Nancy Grace Roman Space Telescope's instrument carrier is a structure that will house the telescope's two instruments: the Wide Field Instrument (WFI) and the Coronagraph Instrument (CGI). The instrument carrier will be located between the telescope's primary mirror and its spacecraft bus.

The WFI is a 288-megapixel multi-band near-infrared camera that will provide wide field imaging and spectroscopy. It will have a field of view that is 100 times greater than the Hubble Space Telescope's infrared instrument, allowing it to survey large areas of the sky quickly and efficiently. The WFI will be used to study a wide range of cosmic phenomena, including dark energy, exoplanets, and the evolution of galaxies.

The CGI is a technology demonstration instrument that will perform high contrast imaging and spectroscopy of exoplanets. It will use a coronagraph to block out the bright light of the host star, allowing it to directly image faint planets. The CGI will be used to study the atmospheres of exoplanets and to search for new exoplanets in nearby star systems.

The instrument carrier is a critical component of the Nancy Grace Roman Space Telescope. It will provide a stable and vibration-free environment for the telescope's instruments, and it will help to protect them from the harsh environment of space.

**Here is a more detailed description of the instrument carrier:**

* The instrument carrier is a carbon fiber structure that is approximately 2.5 meters in diameter and 1.5 meters high.
* It is designed to be lightweight and rigid, so that it can support the telescope's instruments without deforming.
* The instrument carrier has several features that are designed to protect the instruments from the harsh environment of space, including:
* A thermal shield that will protect the instruments from extreme temperatures.
* A radiation shield that will protect the instruments from harmful radiation.
* A dust shield that will protect the instruments from dust and other contaminants.

The instrument carrier is a complex and sophisticated piece of engineering. It is a critical component of the Nancy Grace Roman Space Telescope, and it will play a vital role in the telescope's success.
