Janus: Reconnaissance Missions to Binary Asteroids

Launch Vehicle: SpaceX Falcon Heavy (secondary payload on Psyche mission)
Launch Site: Cape Canaveral Air Force Station, Fla.
Launch Date: July 2022
NASA Program: Small Innovative Missions for Planetary Exploration (SIMPLEx)

Description

Janus: Reconnaissance Missions to Binary Asteroids will study the formation and evolutionary implications for small “rubble pile” asteroids and build an accurate model of two binary asteroid bodies. A binary asteroid is a system of two asteroids orbiting their common center of mass.

The principal investigator is Daniel Scheeres at the University of Colorado. Lockheed Martin will provide project management.

SIMPLEx

Using small spacecraft – less than 400 pounds, or 180 kilograms, in mass – SIMPLEx selections will conduct stand-alone planetary science missions. Each will share their ride to space with either another NASA mission or a commercial launch opportunity.

Janus will be managed by the Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama as part of the Solar System Exploration Program at NASA Headquarters in Washington.

Small Satellites to Study Martian Atmosphere

Escape and Plasma Acceleration
and Dynamics Explorers (EscaPADE)

Launch Vehicle: SpaceX Falcon Heavy (secondary payload on Psyche mission)
Launch Site: Cape Canaveral Air Force Station, Fla.
Launch Date: July 2022
NASA Program: Small Innovative Missions for Planetary Exploration (SIMPLEx)

Description

This mission’s objective is to characterize (on multiple scales) the acceleration processes driving escape from Mars’ atmosphere, as well as how the atmosphere responds to the constant outflow of the solar wind flowing off the Sun.

The principal investigator for this mission is Robert Lillis at the University of California, Berkeley. UC Berkeley will also provide project management.

DENVER  (Lockheed Martin PR) — Lockheed Martin (NYSE: LMT) has been selected to design dual small deep space spacecraft to visit near-earth asteroids in a mission called Janus, led by the University of Colorado Boulder.

One of NASA’s Small Innovative Mission for Planetary Exploration (SIMPLEx) finalists, Janus is designed to fly by two binary asteroids, or asteroids orbiting a common center of mass, to image the system using both visible and infrared cameras. These small satellites will launch in 2022 to reach the asteroid system in 2026.

SIMPLEx Small Satellite Concept Finalists Target Moon, Mars and Beyond

“I think the thing that impressed me the most was the lunar sunrises and sunsets,” said Apollo 8 astronaut Bill Anders as he described his impressions of the Moon from about 60 miles. “These in particular bring out the stark nature of the terrain, and the long shadows really bring out the relief.” This oblique photograph looks northwest into the Sea of Tranquility, the site where Apollo 11 would land seven months later.

WASHINGTON (NASA PR) — NASA has selected three finalists among a dozen concepts for future small satellites. The finalists include a 2022 robotic mission to study two asteroid systems, twin spacecraft to study the effects of energetic particles around Mars, and a lunar orbiter to study water on the Moon. At least one of these missions is expected to move to final selection and flight.

ORLANDO, Fla. (UCF PR) — Sometimes thinking small can get you a big win. That’s certainly the case for a team of physicists at the University of Central Florida.

UCF was one of only two universities selected to prepare an experiment for a miniaturized satellite mission as part of NASA’s Small Innovative Missions for Planetary Exploration (SIMPLEx) program. Twenty-two projects were reviewed and only two were selected for flight, including UCF’s Q-PACE project. The project is a milestone for UCF. It is the first time the university has been selected to design, build and operate a satellite from start to finish.

NASA Selects Two New Deep Space CubeSat Missions

WASHINGTON (NASA PR) — Good things really do come in small packages.

When we think of space satellites that assist with communications, weather monitoring and GPS here on Earth, we likely picture them as being quite large—many are as big as a school bus and weigh several tons. Yet there’s a class of smaller satellites that’s growing in popularity. These miniaturized satellites, known as nanosatellites or CubeSats, can fit in the palm of your hand and are providing new opportunities for space science.
