Last Solicitation Timeline:

ROSES Solicitation Release – February 2021

Step 1 Proposals Submitted – June 2021

Step 2 Proposals Submitted – August 2021

Panel Reviews – October 2021

Solicitation Overview:

HOTTech supports the advanced development of technologies for the robotic exploration of high-temperature environments such as the Venus surface, Mercury, or the deep atmosphere of Gas Giants

The goal of the program is to develop and mature technologies that will enable, significantly enhance, or reduce technical risk for in-situ missions to high-temperature environments with temperatures of 500 Celsius for a period of at least 60 days

  • Radio Frequency (RF) Components or Systems (>100 MHz)
  • Power Transistors/Electronics (>1000 mA)
  • Passive Electronic Components (capacitors, inductors, resistors)
  • Low-Power Electrical Circuits (<1000 mW)
  • Actuators/Motors and associated Lubrication Systems
  • Energy Storage/Batteries/Power Harvesting
  • Sensors/Imaging Cameras

Specific technology readiness levels (TRLs) were not prescribed in the last HOTTech solicitation
