Abstract	We propose a 60ks observation for one new GeV bright nova to explore theparticle acceleration and gamma-ray production mechanisms. We will constrain theparticle acceleration efficiency by comparing thermal X-ray to GeV luminosityand search for predicted non-thermal X-rays. Understanding shocks in novae isr^ant for other shock-powered transients including Type IIn supernovae, tidaldisruption events and stellar mergers. NuSTAR is the only instrument capable ofdetecting X-rays from novae simultaneously with the GeV emission (the lowerenergy X-rays accessible to other focusing instruments are hidden by the novashell at these times). The observations should be conducted now to takeadvantage of the simultaneous operations with Fermi/LAT.

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.
