The Heliophysics Technology and Instrument Development for Science program combines technology elements previously separated within the old Solar, Heliosphere, and Geospace (Magnetosphere –Ionosphere-Thermosphere-Mesosphere Mag-ITM) Science Supporting Research and Technology programs. H-TIDeS seeks to investigate key Heliophysics science questions through three separate subelements. program combines technology elements previously separated within the old Solar, Heliosphere, and Geospace (Magnetosphere –Ionosphere-Thermosphere-Mesosphere Mag-ITM) Science Supporting Research and Technology programs. H-TIDeS seeks to investigate key Heliophysics science questions through three separate subelements: Low-Cost Access to Space (LCAS), Instrument and Technology Development (ITD), and Laboratory Nuclear, Atomic, and Plasma Physics (LNAPP).
 
This amendment makes two changes to this program element: First, it delays the due dates for proposals for this program element. Step-1 proposals are now due June 26, 2015, and Step-2 proposals are now due August 28, 2015. Second, this amendment excludes the EM-1 launch opportunity for CubeSats. Although this program element didn't explicitly include the EM-1 launch opportunity, the ROSES 2015 Summary of Solicitation (Section (V) (b) (v), page 29) that "CubeSats are typically launched as secondary payloads to low-Earth orbit or from the International Space Station, but submissions to ROSES-2015 may also propose to launch on Exploration Mission 1 (EM-1) to achieve Earth-escape." Last year in ROSES-2014 the Exploration Mission 1 (EM-1) opportunity was part of the LCAS subset of H-TIDeS. Therefore, no additional proposals targeting the EM-1 launch opportunity are solicited.
