The ESCAPADE mission – led by the University of California Berkeley Space Sciences Laboratory to study Mars’ magnetosphere – with two Rocket Lab Photon spacecraft has received NASA approval to move toward launch.

LONG BEACH, Calif., 23 August, 2021 (Rocket Lab PR) — Rocket Lab, a global leader in dedicated launch and space systems, today announced it will begin final mission design and commence manufacturing two interplanetary Photon spacecraft for a science mission to Mars, delivering Decadal-class science at a fraction of the cost of typical planetary missions.

 The Escape and Plasma Acceleration and Dynamics Explorers (ESCAPADE) mission will orbit two Rocket Lab-built Photon spacecraft around Mars to understand the structure, composition, variability, and dynamics of Mars’ unique hybrid magnetosphere. The mission will also support crewed exploration programs like Artemis through improved solar storm prediction.

LONG BEACH, Calif.. June 15, 2021 (Rocket Lab PR) — Rocket Lab, a global leader in dedicated launch and space systems, has been awarded a contract to design two Photon spacecraft for a scientific mission to Mars.

The Escape and Plasma Acceleration and Dynamics Explorers (ESCAPADE) mission, led by Rob Lillis at the University of California, Berkeley Space Sciences Laboratory, is a twin-spacecraft science mission that will orbit two spacecraft around Mars to understand the structure, composition, variability, and dynamics of Mars’ unique hybrid magnetosphere. The mission will leverage its unique dual viewpoint on the Mars environment to explore how the solar wind strips atmosphere away from Mars to better understand how its climate has changed over time.

Producing maps to locate ice or water trapped in rock at the Moon’s surface, Lunar Trailblazer will help support NASA’s efforts to establish a sustainable presence on the Moon.


PASADENA, Calif. (NASA PR) — A small-satellite mission to understand the lunar water cycle – detecting and mapping water on the lunar surface in order to investigate how its form, abundance, and location relate to geology – has received NASA approval to proceed with the next phase of its development.

BOULDER, Colo. (NASA PR) — A small satellite mission that will study the formation and evolutionary implications for small “rubble pile” asteroids has received NASA approval to proceed to the next phase of its development.

On Sept. 3, the dual-spacecraft Janus project successfully passed the important Key Decision Point-C milestone. It’s the first concept study from the current round of NASA’s Small Innovative Missions for Planetary Exploration (SIMPLEx-2) program to do so.

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.
