  • Comment: over-reliance on Primary Sources Slywriter (talk) 01:54, 11 January 2022 (UTC)
  • Comment: NASA-produced documents are primary, so don't show notability. Same with the Arizona State University source on LunaH. I don't know why Gunter's Space Page (a blog?) is reliable - what are the author's credentials? And I think that just leaves SpaceNews, which goes some way to notability, but we need multiple sources.
    (By the way, take a look at the difference between "it's" and "its".) — Bilorv (talk) 12:22, 31 December 2021 (UTC)


A 6U Cubesat
The LunaH-Map spacecraft

Small Innovative Missions for Planetary Exploration (SIMPLEx) is a planetary exploration program operated by NASA. The mission builds small, low-cost spacecraft for stand-alone planetary exploration missions. These spacecraft launch as secondary payloads on other missions. The missions are riskier that Discovery or New Frontiers missions.[1]

The program selects missions from multiple proposals and gives them some money to begin development. After early development they are analyzed to see if they are cost-effective and scientifically valuable during Key Decision Point-C. If they pass Key Decision Point-C then they move into full development. The missions must weigh less than 180 kg.[2][3]

Missions

On September 1st, 2015, the first two SIMPLEx missions were selected: Q-PACE and LunaH-Map. They were both CubeSats and each had a maximum budget of $5.6 million.[4] Q-PACE launched on a Virgin Orbit LauncherOne as part of the ELaNa 20 mission. LunaH-Map is a 6U CubeSat that will map hydrogen on the moon. The mission will launch as a secondary payload on Artemis-1.[5][6]

Three SIMPLEx-2 missions were selected in 2019. Janus will launch with Psyche and fly past multiple binary asteroids. Lunar Trailblazer will launch with IMAP to study the Moon's geology and map its water.[7] EscaPADE will send two small satellites to Mars to study its atmosphere.[2]

So far, only one mission in the SIMPLEx program has launched.

SIMPLEx missions
Name Selection Target Launch Date
Q-PACE SIMPLEx-1 Early Protoplanetary Disks 17 January 2021
LunaH-Map SIMPLEx-1 Moon August 2022
Janus SIMPLEx-2 Binary Asteroids August 2022
Lunar Trailblazer SIMPLEx-2 Moon February 2025
EscaPADE SIMPLEx-2 Mars 2024

Q-PACE

Main article: Q-PACE

Q-PACE is a 3U CubeSat that would have studied the interactions of small particles in space in order to better understand early protoplanetary disks. The mission launched on January 17th, 2021 on Virgin Orbit's LauncherOne as part of NASA's ELaNa program. Contact was never established with the CubeSat.[8][9]

LunaH-Map

Main article: LunaH-Map

LunaH-Map (Lunar Polar Hydrogen Mapper) is a 6U CubeSat that will map Hydrogen on the Moon using a neutron spectrometer. This mission will launch as one of ten secondary payloads on Artemis 1. The mission was designed, built, and tested by Arizona State University. In will take over a year for LunaH-Map to reach its science orbit. After that, its 60 day science mission will begin.[10][11]

Janus

Main article: Janus

Janus will send two small spacecraft to explore binary asteroids. The two spacecraft will launch with Psyche in August 2022 on a Falcon Heavy rocket. The two identical spacecraft (Janus A and B) being built by Lockheed Martin. The spacecraft are powered by solar panels and rechargeable batteries.[12][13]

Lunar Trailblazer

Main article: Lunar Trailblazer

Lunar Trailblazer will study water ice on the moon and determine how it formed, how common it is, and where it is. The small spacecraft will be capable of looking inside permanently shadowed craters for water ice. The mission is managed by NASA's Jet Propulsion Laboratory. The spacecraft is scheduled to be completed in 2022 and will launch as a secondary payload alongside IMAP in 2025.[14][15] Since the spacecraft will be ready years before it is scheduled to launch, NASA is looking for other launch opportunities.[8]

EscaPADE

EscaPADE (Escape and Plasma Acceleration and Dynamics Explorers) will send two identical spacecraft to Mars. The spacecraft will be built by Rocket Lab and will be based on its Photon spacecraft bus. EscaPADE will study Mars' magnetosphere and how it has lead to Mars' losing much of its atmosphere. The mission was originally going to launch with Janus and Psyche, but will not be able to. NASA has not yet found a different rideshare opportunity.[16][17][18]
