So far, it has been observed only for hot-Jupiters. Nonetheless, lower-mass hot-Neptunes should be significantly impacted by this phenomenon, thought to be driven by the absorption of stellar X/EUV radiation in the upper layers of the atmosphere. Here, we propose to detect atmospheric escape from a hot-Neptune, GJ 436b. This planet transits a nearby, quiet M dwarf. We demonstrated with HST/STIS in a past Cycle that this star is a bright Lyman-alpha target. Hence, we will use this same instrument to measure the properties of the upper atmosphere of this hot-Neptune, constrain its escape rate, and search for temporal variations in its exosphere, thus bringing new insights on the physics of the atmospheric escape for a completely different range of masses. We also propose coordinated Chandra observations of GJ 436b's transits to measure the atmospheric escape efficiency factor and test the impact of stellar X-ray variability on the atmospheric properties of the planet. This program consists in 3 visits of 4 orbits. In each visit, we will observe the transit of an exoplanet in front of its star. Transits occur every 2.64 days (the orbital period of the planet) and last for about 1h. The timing requirements are set as phase constraints on the first ACQ exposure of the first orbit in a visit. The goal is to observe the star during two HST orbits before the transit, so that the transit can be completely covered by the third orbit. The fourth orbit occurs after the transit and serves to establish a (critical) posterior reference. The phase constraints given for the first orbit authorize a margin of 7-8 min. This is a joined HST-Chandra program. HST and Chandra should observe the same three transit events, meaning that HST and Chandra visits should be synchronized. Note, however, that the phase constraints given to Chandra are more relaxed (with start phase between 0.87 and 0.93) than for HST. Chandra will typically start to observe earlier (a couple of hours) than HST.
