Charles Messier 1730 – 1817

wanted to be known for finding cometsfound 13 – a good feat

now know for publishing a list of "dim fuzzies" that are not comets

used a 100 millimeter aperture telescope

Our solar system

• sun

• planets & moons

• plutinos

• asteroids

• comets

icy planetesimals

• Ort cloud

• Kuiper belt objects

• long period comets

• short period comets

Solid or Rubble Pile?

• components in contact

• regolith

• voids

to change orbit of comet

• High Energy Collision• Boiloff / Jet Effect• Attach Motor• Gravity Tug

High Energy Collision

• Direct Impact• Science Fiction:Science Fiction:

Tethered Momentum Transfer

Boiloff / Jet Effect

• Sunshine (Mirrors) • Nuke

standoffsurface burstburst in previous crater

Pusher Tugboat

• “lands” on asteroid

• secured with guy wires

• periodically fires engine when asteroid rotates to desired direction

• long term effort

Puller Tugboat

• massive ship

• gravity as towline

• long duration low level ion thrust

• no direct contact, physical proproperties of NEO unimportant

Tug using Gravity Towline

Gravity Tug Built from NEO

• seed ship (factory)

• build factory inside NEO

• build Tug at top of tower

• shift mass to Tug & launch

• use part of NEO as reaction mass

Cargo Ship

• harvest regolith

• or capture “small” object

mass driver cargo ship uses part of payload as reaction mass

Attach Motor(s)

• Rendezvous• (Mine)• Attach (Build) Engine(s)• Despin and Move

S.S.S. DaKasKova

• seed ship (factory)

• build manufacturing facilities

• build “jet” engines at top of towers

• build radiators & solar collectors

• use part of comet as reaction mass
