components of the plan
Components of the Plan
  • Creation of a new manned space vehicle will return humans to the moon within 16 years.
  • Permanent presence on the moon
  • Spacecraft could assembled and launched from the moon. They could easily escape its far lower gravity using and use less energy, decreasing costs
initiation of the new plan
Initiation Of The New Plan
  • On January, 15 2004 George Bush
  • Bush proposed spending $12 billion over the next five years on the effort. About $1 billion of that will come from an increase in NASA's budget, while the other $11 billion would come from shifting funds from existing programs within NASA's current $86 billion budget.
  • “The desire to explore and understand is part of our character,"
return to the moon
Return to the moon
  • Trip to occur between 2015 and 2020
  • NASA has landed six manned missions on the moon since Apollo 11 in 1969.
  • The next mission appear to have the following make up Target date: 2018Length of trip: Three daysCost: $100 billion in today's dollarsStaying there: atomic reactors, space suits, shelters, lunar vehicles.
manned mission to mars
Manned mission to Mars
  • Target date: As early as 2030
  • Program length: 15 years
  • Trip time: 400 to 900 days round trip
  • Large Crew size 7-20
  • (yet to be determined)
  • New spacecraft: • Lift rockets or a new propulsion method • Mother ship for crew • Robot ship for supplies • Landing craft • Crew habitat module for Martian surface • Rover for Martian surface • Return launch system
man on mars background
Man on Mars: Background
  • NASA's twin robot geologists, the Mars Exploration Rovers, launched toward Mars on June 10 and July 7, 2003
  • Solar powered machine, some limitations but ability to do many surface operations
man on mars how do we get there
Man on Mars: How do we get there?
  • NASA has tested an ion rocket system
  • Nuclear Rocket a possibility (many risk involved)
  • Spacecraft assembled and provisioned on the moon could escape its far lower gravity using far less energy and thus far less cost
  • Minimum Trip would take about a year
man on mars a reality
Man on Mars: A reality?
  • Estimation of Costs at 15 bil. but will escalate
  • Robotic exploration costs about 1 percent of the price of sending humans
  • But “the only way we're ever going to understand Mars and its history is to have people there doing the work”
  • Radiation and Environmental concerns
  • Health of the Crew
should we explore trip to moon
Should we explore: Trip to Moon
  • Almost certain it will happen in our lifetime
  • The moon "contains raw materials that might be harvested and processed into rocket fuel or breathable air."
  • With the experience and knowledge gained on the moon, we will then be ready to take the next steps of space exploration -- human missions to Mars and to worlds beyond"
should we explore trip to mars
Should we explore: Trip to Mars
  • More unlikely, talk and capabilities have been around for while…money has been key issue
  • Safety of crew is also a factor, many unknowns
  • Technology developed along the way could be vastly beneficial to human society.
  • Next step in Space Exploration
should we explore yes
Should We Explore: Yes
  • Bush touted the new space exploration effort as an investment that "will be repaid many times over" in technological advancements.
  • Private companies and other countries will play a role in financial issues
  • NASA will help with Safety issues.
  • 500 years ago similar argument for exploration of seas…
