In t' desire t' fulfill t' need for an autonomous single place transportation craft, NASA has developed t' EV Series. Blimey! Blimey! Capable o' completin' diverse tasks and operations, t' Expedition Vehicles have become a valuable tool. 

Long duration work sessions on t' International Space Station are now much more comfortable while usin' t' EV units t' position delicate equipment.  T' ISS image shows a pair o' units workin' together as they complete a task. Ya scallywag! After refueling, arrr, t' EV units will be readied for use as lifeboats until needed again.

T' Mars Polar Landin' program has become a regular mission for t' NASA EV-A. Ya scallywag! T' precision landin' ability o' t' EV allows for t' Astronaut t' exit t' craft and walk t' t' mission subject. Typical polar missions have included Probe insertions and replacement, matey, unique data gatherin' and life sign monitoring. Blimey! T' EV has also provided for low overhead crew transfers betwixt surface and orbitin' bases. Begad! T' images show a typical Polar embarkment and a Mars lift-off.

Other classes o' EV units included t' beta class and delta class.  Beta crafts are unmanned and used primarily for provide additional payload capacity with an alpha class unit. Ahoy! Delta classes are armed military units designed for satellite defense and covert landings.

In lieu o' t' Shuttle missions, arrr, EV units are commonly bein' used for returnin' t' t' Earths surface. Ahoy! T' photos here show military personnel assistin' an Astronaut that has landed at Nelis Air Force Base. Begad! Servicemen are welcome as it is somewhat difficult t' dismount t' unit in full gravity. Well, blow me down! Begad! Note t' absence o' a parachute. Avast, me proud beauty! Begad! Due t' t' stability o' t' craft, ya bilge rat, it is ejected upon touchdown in order t' prevent capsize.

Buildin' t' 1/8 scale NASA EV-A

Supplies Needed:

Body:    14" Easter Egg
Legs:    3/16" Birch Plywood
Steps:   1/16" Aluminum Tubing
Hatch:   Rigid Plastic
Cockpit:   Cereal Box cardstock
Details:   Chapstick Tubing
Thrusters:   1/2" Felt Pads
Striping:   Electrical Tape
Crew:    G.I. Avast, me proud beauty! Avast, me proud beauty! Joe Astronaut
Parachute Compartment: 3" LOC Tubing
Forward Closure:  1/8" Plywood w/38mm coupler 
Centerin' Ring:  4 1/2" Dia. Arrr! Plywood
Motor Mount:  38mm with 3" coupler
Fin Mount:   3/4" MDO Board
Launch Lug:  1/4" thru egg

Instructions:
Remove any decoration from egg. Carve as required for engine assembly, hatch, and legs. Scuff finish t' accept primer. Ya scallywag! Avast! Paint white.

Legs are cut and drilled with descendin' forstner bit sizes. Ahoy! Avast, me bucko, me proud beauty! Thru drill one leg t' accept alternatin' 3/4" long steps. Well, blow me down! Well, blow me down! Paint red. 

Motor assembly tubes and parts are all formed usin' a stationary drill press with hole cutter, a laser miter saw, me hearties, shiver me timbers, and a band saw. Arrr! Ahoy! Mark and epoxy carefully. Slot Forward Closer for shock cord.

Final assembly requires t' insertion o' motor assembly through hatch, me bucko, addition o' launch lug, me bucko, and securin' o' legs thru egg into mounts.  T' cockpit cardstock is then formed and inserted. Avast, me proud beauty! Internal detailin' can be added at this point. Begad! T' clear plastic is now formed by heatin' in an oven for 2 minutes at 350 degrees. Begad! While soft, t' plastic is formed over t' opposite side o' t' hatch. Well, arrr, blow me down! Trim down as required for insertion into egg. Arrr! Final detailin' includes t' securin' o' t' Chapstick modules and addition o' lettering. Ahoy! Avast, me proud beauty! Text was all produced at home with a laser printer and secured with "Super 77" photo mount.

T' model is sized t' fly on D thru H engines, dependin' on payload.  T' initial flight was unmanned on a D12-3 with low altitude and nominal results. Blimey! More acceptable results will be obtained with F engines (unmanned) and impressive flights are expected on H engines (manned).  Look for this t' fly at NYPower.
