Fermi Gamma-ray Space Telescope

The Fermi Science Support Center (FSSC) runs the guest investigator program, creates and maintains the mission time line, provides analysis tools for the scientific community, and archives and serves the Fermi data. This web site is the portal to Fermi for all guest investigators.

This view shows the entire sky at energies greater than 1 GeV based on five years of data from the LAT instrument on NASA's Fermi Gamma-ray Space Telescope. Brighter colors indicate brighter gamma-ray sources.

Look into the "Resources" section for finding schedules, publications, useful links etc. The "Proposals" section is where you will be able to find the relevant information and tools to prepare and submit proposals for guest investigator projects. At "Data" you will be able to access the Fermi databases and find the software to analyse them. Address all questions and requests to the helpdesk in "Help".

Fermi Observations for MW 541

Mission Week 541 starts with a brief continuation of the fixed +50 degree rock profile from MW 540. On day 284 at 00:05z there is a 10 minute freeze observation during which an updated +50 degree rock profile is loaded. This profile continues for the remainder of the week. Note that positive rock angles are south, and negative angles are north.
