On February 28th 2007, the New Horizons (NH) spacecraft will flyby Jupiter for agravity assist to Pluto. Closest approach (C/A) is 32 Jupiter radii, but the NHinstruments will conduct intensive studies from C/A-52d to C/A+100d. Importantnew studies of auroral and magnetospheric physics are planned that may be well-supported by Chandra observations. Chandra support of the Cassini flyby ofJupiter in 2000 led to a major revision of our understanding of Jupiter.s x-rayaurora. We propose 108ks of Chandra time to support three planned NHinvestigations; a time-variability study during approach, a multi-spectralmorphology study near C/A, and a magnetotail dynamics study as NH heads toPluto. In addition, we request 72ks of XMM-Newton time to investigate spectral differences at low energy.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
