The Mars Exploration Program

Space technology and applications international forum (STAIF - 97), 1997
The Mars Exploration Program was initiated in 1994. It currently consists of a Discovery mission (Mars Pathfinder which will land in 1997) and the Mars Surveyor Program. The objectives of the Mars Surveyor Program are to launch 2 robotic missions every 26 months to address the three themes of Life, Climate, and Resources, with the focus of initial ...

NASA's New Mars Exploration Program: The Trajectory of Knowledge

Astrobiology, 2001
NASA's newly restructured Mars Exploration Program (MEP) is finally on the way to Mars with the successful April 7 launch of the 2001 Mars Odyssey Orbiter. In addition, the announcement by the Bush Administration that the exploration of Mars will be a priority within NASA's Office of Space Science further cements the first decade of the new millennium ...

Mars Exploration Program Analysis Group Goal One: Determine If Life Ever Arose on Mars

Astrobiology, 2010
The Mars Exploration Program Analysis Group (MEPAG) maintains a standing document that articulates scientific community goals, objectives, and priorities for mission-enabled Mars science. Each of the goals articulated within the document is periodically revisited and updated.

Advanced electronics developed for NASA's Mars Exploration Program

2005 IEEE Aerospace Conference, 2005
Six electronic technologies under development for the Mars Technology Program are discussed. The scope of this set ranges from electronic packaging to microprocessors to power supply to communication technologies. An overview (motivation, objective, approach) of these six projects is presented, along with a comparison to the state-of-art.

“Mars on $300K a day”: The Mars exploration program

Acta Astronautica, 1996
Abstract The Mars Exploration Program is pioneering a series of “better, faster, cheaper” missions to Mars over at least the next 10 years, and possibly well into the 21st century. The overall cost of the program is somewhat over $100M per year, including launch vehicles and operations, for two launches every 26 months. (This works out to about $300K

Following the water, the new program for Mars exploration

Acta Astronautica, 2002
In the wake of the loss of Mars Climate Orbiter and Mars Polar Lander in late 1999, NASA embarked on a major review of the failures and subsequently restructured all aspects of what was then called the Mars Surveyor Program--now renamed the Mars Exploration Program.

Mars Exploration Rover Parachute Decelerator System Program Overview

17th AIAA Aerodynamic Decelerator Systems Technology Conference and Seminar, 2003
In the Mars Exploration Rover (MER) Mission, NASA returns to the red planet, following the extremely successful Mars Pathfinder in 1997. The mission will send two lander-rovers to the surface of Mars with separate launches in May and June, 2003. This paper describes the Parachute Decelerator System for the entry vehicle.

Mechanisms for Lowering Tethered Payloads: Lessons Learned from the Mars Exploration Program

2008 IEEE Aerospace Conference, 2008
Compact, lightweight, highly reliable lowering devices capable of paying out tether to lower a payload some number of meters with exacting performance, from a balloon or a parachute or part of a spacecraft, typically appear in systems so unique that there is little historical precedent to build upon when preparing designs.

Mars Technology Program Communications and Tracking Technologies for Mars Exploration

2006 IEEE Aerospace Conference, 2006
The future of the exploration of Mars see an unprecedented increase in the volume of data generated by an increasingly capable host of science instruments on various rovers, aerobots, orbiters and eventually humans on Mars. To return these large volumes of data to Earth, communication links with data-rate capabilities in the multiple megabits-per ...
