When it comes to picking the next mission to explore the solar system, NASA certainly has options. The space agency is reviewing a dozen ideas for a robotic solar system probe that will launch sometime in the mid-2020s. 

The 12 mission proposals are part of NASA's New Frontiers program, which aims to send ambitious missions to explore the solar system with a cost of no more than $1 billion. Past New Frontiers missions include the New Horizons probe that flew by Pluto in 2015, the ongoing Juno mission at Jupiter and the OSIRIS-REx mission, which will visit the asteroid Bennu and return samples to Earth.

"New Frontiers is about answering the biggest questions in our solar system today, building on previous missions to continue to push the frontiers of exploration," Thomas Zurbuchen, NASA's associate administrator for science missions, said in a statement. "We're looking forward to reviewing these exciting investigations and moving forward with our next bold mission of discovery." [These Are All the Probes Exploring the Solar System]

NASA did not list the details of the 12 candidate New Frontiers mission proposals, but officials said each was submitted under one of six different themes. Those themes are:

  • Comet Surface Sample Return
  • Lunar South Pole-Aitken Basin Sample Return
  • Ocean Worlds (Titan and/or Enceladus)
  • Saturn Probe
  • Trojan Tour and Rendezvous
  • Venus In Situ Explorer 

NASA will announce the selection of one or more concepts for a Phase A study in November, agency officials wrote in the statement. Once the Phase A study round is complete, NASA officials plan to select a final New Frontiers proposal to advance into "subsequent mission phases," NASA officials said. "Mission proposals are selected following an extensive competitive peer review process."
