NASA has comparison a heavenly goal involving a group from a University of Arizona as one of dual finalists to be a subsequent robotic solar complement explorer. The due mission, named CAESAR, for Comet Astrobiology Exploration Sample Return, seeks to lapse a representation from a comet to establish a start and history.
UA Lunar and Planetary Laboratory professor Dante Lauretta is CAESAR’s goal representation scientist, obliged for heading a investigate of a returned comet sample. He also is tasked with advising on all aspects of a mission’s pattern that change a systematic value and firmness of a sample. Lauretta is now principal questioner of NASA’s OSIRIS-REx asteroid representation lapse mission, that launched in Sep 2016 and will lapse NASA’s initial asteroid representation to Earth in 2023.
LPL associate professor Tom Zega is a co-investigator on a CAESAR goal and would investigate a comet representation element once it is behind on Earth. Zega, now a co-operator on a OSIRIS-REx mission, will be one of a initial scientists to investigate samples from a asteroid Bennu.
“We are vehement to move a UA’s care in representation scholarship creation to a hurdles acted by a CAESAR goal and a aim comet,” Lauretta said. “The work finished on CAESAR will safeguard that a UA continues to mount during a forefront of supernatural representation investigate for a subsequent 20 years.”
If selected, CAESAR would be a fourth goal in NASA’s $1 billion New Frontiers program, that sends robotic booster to control science-intensive heavenly investigations. The UA leads a third New Frontiers mission, OSIRIS-REx, now on a approach to a asteroid Bennu to collect a representation of a aspect for investigate on Earth.
“This is a smashing event to request a knowledge that a UA has gained from OSIRIS-REx to another limit in heavenly science,” said Kimberly Andrews Espy, UA comparison clamp boss for research. “We are gay to be means to continue a University’s tradition of care in well-developed NASA missions.”
CAESAR’s aim comet is 67P/Churyumov-Gerasimenko, that formerly was explored by a European Space Agency’s Rosetta spacecraft. If a goal is eventually chosen, a CAESAR booster could launch by 2025 and lapse to Earth in 2038. The goal is led by Steve Squyres of Cornell University and managed by NASA’s Goddard Space Flight Center. NASA intends to make a final goal preference in summer 2019. Between now and then, a dual finalist missions will accept appropriation from NASA to serve allege a missions’ concepts and designs.
The other finalist mission, Dragonfly, is led by LPL alumna Elizabeth Turtle, who warranted her Ph.D. in heavenly scholarship in 1998 and afterwards continued during LPL as both a postdoctoral associate and as investigate expertise before fasten a Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. The Dragonfly booster is a dronelike rotorcraft that would try a prebiotic chemistry and habitability of dozens of sites on Saturn’s moon Titan, an sea universe in the solar system.
