Current IPN Developments
In the year 2007 AGILE was launched and on 2008 the Fermi Gamma-ray Space Telescope and although these are Earth orbiters, their instruments provide directional discrimination. The Fermi Space Telescope uses both wide-area burst detectors and a narrow-angle telescope, and will have a limited ability to spin itself to place a GRB within the telescope field. MESSENGER's gamma instrument is now fully operational, and is adding data to the IPN. Due to falling power from its RTG, Ulysses last day was June 30, 2009.

Famous quotes containing the words current and/or developments:
“A reaction: a boat which is going against the current but which does not prevent the river from flowing on.”
—Victor Hugo (1802–1885)
“The developments in the North were those loosely embraced in the term modernization and included urbanization, industrialization, and mechanization. While those changes went forward apace, the antebellum South changed comparatively little, clinging to its rural, agricultural, labor-intensive economy and its traditional folk culture.”
—C. Vann Woodward (b. 1908)
