Laura is the remote-controlled submersible designed and constructed for the 2009-10 mission Daedalus to Europa, Ganymede, and Io.
Design
Laura is approximately 35cm in length, with a main hull width of approximately 8cm and a maximum width (including propeller nacelles) of approximately 20cm. She has three engines, two for horizontal thrust and one for vertical movement. Her top cover is removable, to allow access to her power cell, engine test mechanism, radio emitter and receiver, and sonar equipment. There is additional space inside her main body for other mechanisms and equipment to be added to suit the purposes of the mission. Attached to her hull are four removable sample collectors.
Deployment
Laura was designed to be deployed on ice-covered planets (for example, [[1]]), and so is fitted with an ice-boring capsule. This capsule uses heaters to melt a small tunnel through the ice, assisted by gravity, or, if gravity is insufficient, by treads. Once it reaches liquid water, the capsule hooks itself into the ice shelf, and remains there while Laura detaches. Once separate from the capsule, she uses active and passive sonar to observe her surroundings, and transmits the information back to the capsule via radio signals. These signals are then relayed by the capsule to the Habitat via a tether cable. Likewise, control signals from the Habitat are sent through the tether to the capsule, which then transmits them to Laura using radio signals.
Software
Laura is remote controlled from inside the Habitat, using software designed by Jim Magwood. This software allows the user (typically a Mission Specialist) to control the submersible's attitude, velocity, depth, and sample collectors, by means of a rudder, dive planes, three propellers, and ballast loads. The software also gives the user a graphic display of Laura's passive sonar, active sonar, and fathmometer readings, as well as giving numerical data on water temperature, depth, and sonar contact distance.
Construction
Laura was contributed to by several members of OCESS, in an intermittent Task Force spearheaded by Mission Commander Maclean Rouble. Contributors included Jane MacLeod and Christian Angel. She is built primarily out of black PVC tubing, with clear plexiglass sides and lid. The sample collectors follow the design of syringes, and have matching sample storage containers aboard the Habitat in the form of narrow, clear plastic cylinders.
Additional Information
- Laura's name is a reference to the 2004 television series [Galactica], which featured a specially-designed stealth [spacecraft] known as "Laura", named after the dying Colonial President, [Laura Roslin], a primary character in the show.
- Laura is painted yellow, as a reference to the [Beatles'] song, "[Yellow Submarine]", which has been rewritten by OCESS members on many occasions and is a prominent part of Sim Lore.
Laura is the name of a submersible being created for the 2009-10 mission. It is painted yellow as a reference to the Beatles song "Yellow Submarine". Laura is to be piloted by a Mission Specialist to collect samples from underwater and to search for life forms.
