JWST is poised to transform our understanding of exoplanet atmospheres, as exquisite near-IR spectra will soon be obtained providing a detailed look at molecules such as H2O, CO, CH4 and CO2. Because JWST can only observe past 0.6 um, HST will be required to observe at shorter wavelengths into the NUV. Working together, these two powerful observatories can probe a planet's atmosphere all the way from the far UV to the mid-IR. The transit exoplanet community's very first look at JWST data will come from the Early Release Science (ERS) program which is targeting the Saturn-mass planet WASP-39b. This will be the only exoplanet where ALL of JWST's near-infrared instruments will be used on the same target in a manner that enables detailed instrument comparisons, resulting in a legacy high-quality spectrum. WASP-39b is an important gas giant planet as it is still the only one known to show evidence of a very-high metallicity, indicating a differing formation mechanism than other planets. However, there is a startling controversy in the literature regarding the true metallicity, as the current HST/STIS data suffers from calibration offsets and a highly uncertain NUV spectrum. By combining six HST/UVIS transits of WASP-39b, a precision NUV to optical spectrum can be obtained with Hubble that will be comparable in quality to those obtained with JWST. With a new high precision HST and JWST ultra-broadband transmission spectrum, the metallicity controversy can be resolved enabling an accurate insight into its formation history. WASP-39b offers a unique chance to fully probe the synergy between HST and JWST, exploring the true limits of atmospheric characterization. To construct a broadband transmission spectrum, we need to observe our target with the WFC3 UVIS/G280. That wavelength coverage provides maximum leverage to quantify the Rayleigh scattering slope, as the extinction and transit depths are expected to be very strong. The wavelength coverage provided by the instrument will be 0.2-0.8 um. This grism is necessary to cover cloud scattering at short wavelengths plus Na and K. The observing strategy for transiting exoplanets consists of taking repeated exposures for the duration of each transit, plus time before and after the transits to establish the out-of-transit baseline flux. We note that the use of WFC3/UVIS for this purpose have proven to be successful for recent HST programs (e.g. GO-15288 and 16086). Prof. Sing is an expert in the analysis and interpretation of transiting exoplanets with space-based observatories, leading many HST observing programs targeting transiting planets over the last 10 cycles including small, large, and Treasury programs. He has published 43 refereed papers over the last 12 years on space-based transiting exoplanet data. Prof. Sing has additional expertise in retrieval analyses of exoplanet atmosphere data. Z Rustamkulov is a PhD student working with Prof Sing, and is an expert in the reduction of transiting exoplanet data and in atmospheric modeling for exoplanets. Dr Moran is an expert in exoplanetary clouds and hazes and their effect on transmission spectra both theoretically and experimentally. She is a Co-I on several HST observing programs with a cloud and haze focus. Dr Wakeford is an expert in observations and modeling of transiting exoplanet atmospheres. She is a PI or CO on numerous HST observing and theory programs, and pioneered the use of UVIS for transiting exoplanet science. Dr Stevenson is an expert in transiting exoplanet observations. He is a PI or Co-I on 30+ HST observing programs dating back to 2014 and is an author on 30+ peer-reviewed papers relating to those programs. Dr May is an expert in exoplanet atmospheric observations with both ground and space-based telescopes including HST and Spitzer. She also has expertise in 3D climate models to better understand variability in exoplanet atmospheres. Dr Lothringer is an expert in modeling exoplanet atmospheres and interpreting space-based observations. He is PI or co-I on 14 HST observing and theory programs. G. Fu, L. Ramos, W. Balmer, and N. Allen are PhD students at JHU advised by Prof. Sing and are focused on the observations of transiting exoplanets.
