This paper, the first of three, compares the merits of current or planned missions to Jupiter and Europa and then proposes a lander vehicle for studying Europa. It outlines the launch vehicle and spacecraft, the mission trajectory, and potential spacecraft instruments. It estimates power consumption, cost, and schedule for a mission to Europa.
This paper, the third of three, proposes a configuration for a lander vehicle for studying Europa. It outlines the network and power distribution for the instruments. It proposes burying the electronics in ice to shield them from radiation. It proposes a method for assembling the spacecraft in an autoclave to provide planetary protection, as well as, flying the boosters and sky crane away from Europa...
The International Rosetta Mission, a cornerstone mission of the European Space Agency (ESA), will both land on, and study the nucleus of comet 67P/Churyumov-Gerasimenko and its environment, for a period of 17 months starting in August 2014. Measurements will begin at a heliocentric distance of about 3.25 AU, after which a Lander (designated ‘Philae’) will be deployed. The Lander mission will last...
Spacecraft processors and memory are subjected to high radiation doses and therefore employ radiation-hardened components. However, these components are orders of magnitude more expensive than typical desktop components, and they lag years behind in terms of speed and size. We have integrated algorithm-based fault tolerance (ABFT) methods into onboard data analysis algorithms to detect radiation-induced...
The Aeronomy of Ice in the Mesosphere (AIM) Mission is the first detailed exploration of Earth's Polar Mesospheric Clouds (PMCs). AIM was selected from NASA's 1999 Small Explorer (SMEX) Announcement of Opportunity to accomplish the first detailed observations of these clouds to aid our understanding of how and why they form. Polar Mesospheric Clouds form during the polar summers. These clouds have...
Missions to explore Europa have been imagined ever since the Voyager mission first suggested that Europa was geologically very young. Subsequently, Galileo supplied fascinating new insights into that satellite's secrets. The Jupiter Europa Orbiter (JEO) would be the NASA-led portion of the Europa Jupiter System Mission (EJSM), an international mission with orbiters developed by NASA, ESA and possibly...
