CLLARE Proposal/Ultralight
From CSTART Wiki
Contents |
[edit] Proposal Name
The name of this CLLARE Proposal is "Ultralight".
[edit] Brief Summary
This proposal involves a radically minimalist approach to manned lunar landing. It involves having the astronaut spend the entire duration of the flight, from take off to landing on Earth, in a spacesuit. During the flight, the astronaut is harnessed into a very simple spacecraft, a frame with no pressurised cabin, which provides propulsion via attached rockets as well as houses avionics to deal with issues such as navigation, communication, etc.
This proposal is similar in many ways to minimalist lunar landing plans being developed by the Open Luna Foundation and the Microspace company.
[edit] Core Hardware Items
Use this space to list the important, large items of hardware involved in the proposal. For example, if the Apollo project were a CLLARE proposal, this section would look like:
- Command Module (CM)
- Service Module (SM)
- Lunar Modular (LM)
[edit] Basic Flight Plan
Launch vehicle: INSERT LV NAME HERE (Must be a launch vehicle which is operational or is expected to be operational within 5 years)
Flight profile: INSERT PROFILE HERE (Must be one of Direct Ascent (DA), Earth Orbit Rendezvous (EOR), Lunar Orbit Rendezvous (LOR), or a combination of these, e.g. EOR-LOR)
Reentry mechanism: The minimalist, open frame spacecraft used in this proposal cannot be expected to survive reentry, so options are limited to "personal heat shield" solutions such as MOOSE or Paracone.
Short description: Use this space to briefly (one paragraph) summarise the flight plan.
Abort options: Use this space to outline the proposal's possible abort options at every stage of the flight plan.
[edit] Basic Feasibility Analysis
Use this space to provide a basic feasibility analysis for the proposal. The analysis must include realistic mass estimates for the Core Hardware Items, realistic delta v estimates for all major propulsive maneuvers, and an application of the Tsiolkovsky rocket equation to show that the total, fueled mass of the hardware is within the maximum payload limits of the proposed launch vehicle, using a figure for specific impulse which is a realistic estimate for the proposed propellants.
If the analysis is long and tedious or has been achieved using, e.g, a spreadsheet file, then a link may be placed in this space to a separate Wiki page or an external file containing the analysis.
[edit] Selling Points
Use this space to honestly list the attractive features of the proposal
[edit] Major Challenges or Obstacles
- The inability to remove the spacesuit at any stage during the flight requires the suit to have exceptional capabilities with regards to such issues as food and drink provision, waste management, etc.
- Astronaut receives minimal radiation shielding.
[edit] Supporting Material
An arbitrary amount of material relevant to making the case for the proposal may be included in this space.
