In August 2019, NASA awarded the ''Solar Cruiser'' team $400,000 for nine-month mission concept studies. The spacecraft would have a {{cvt|1672|sqm}} solar sail and would orbit the Sun in a polar orbit, while the [[coronagraph]] instrument would enable simultaneous measurements of the [[Sun#Magnetic field|Sun's magnetic field]] structure and velocity of [[coronal mass ejection]]s.<ref name='PR Helio'>[https://www.nasa.gov/press-release/nasa-selects-proposals-to-demonstrate-smallsat-technologies-to-study-interplanetary NASA Selects Proposals to Demonstrate SmallSat Technologies to Study Interplanetary Space.] NASA press release, 15 August 2019.</ref> If selected for further development, it would have launched in 2025. However, ''Solar Cruiser'' was not approved to advance to phase C of its development cycle and was subsequently discontinued.<ref>{{cite web |last=Christe |first=Steve |url=https://hesto.smce.nasa.gov/2023/08/02/solar-cruiser-enabling-new-vistas-for-heliophysics-science/ |title=Solar Cruiser: Enabling new vistas for Heliophysics Science |work=Heliophysics Strategic Technology Office |publisher=[[NASA]] |date=2 August 2023 |access-date=5 December 2023}}</ref>
