Re: JPL Mars mission proposal

This post may deserve its own seperate topic but I will post here and see if we should.... break it out later....

Spending Bill To Accelerate NASA Habitation Module Work

boeing-nextstep-879x485.jpg

Boeing is one of four companies with study contracts from NASA to study habitation module concepts. Funding provided in the 2016 omnibus spending bill, and attached report language, could accelerate that work

omnibus spending bill passed by Congress this month directs NASA to accelerate work on a habitation module that could be used for future deep space missions, bill instructs NASA to spend at least $55 million on a “habitation augmentation module” to support the agency’s exploration efforts. The money would come from the Advanced Exploration Systems program, part of the Exploration Research and Development line item in the budget that received $350 million.

Language in the bill states

“NASA shall develop a prototype deep space habitation module within the advanced exploration systems program no later than 2018,” the report states. It also requires NASA to provide Congress with a report within 180 days of the bill’s enactment on the status of the program and how it has spent the funds provided.

What Nasa was already doing for a deep habitat design:

The agency has instead funded several industry studies of habitation module concepts. Under its Next Space Technologies for Exploration Partnerships, or NextSTEP, program, NASA awarded study contracts in March to Bigelow Aerospace, Boeing, Lockheed Martin and Orbital ATK to study habitat designs. It also awarded contracts to Dynetics, Hamilton Sundstrand and Orbital Technologies Corp. for specific module technologies, such as life support systems.

The NextSTEP contracts, valued at up to $1 million each and lasting for one year, will inform NASA’s plans for later habitat development work. “We plan to leverage the output of those studies to shape our plan and then go to a next round,” Scimemi said, adding that NASA hadn’t settled on the details of that next phase.

NASA's Not Ready to Go to Mars, Panel Finds

http://oiir.hq.nasa.gov/asap/documents/ … Report.pdf

Aerospace Safety Advisory Panel (ASAP), an external advisory group that makes safety recommendations for NASA, strongly questions whether the space agency can safely live up to its timetable for a Mars mission in the 2030s.

http://www.nasa.gov/sites/default/files … 08_508.pdf

NASA roughly outlined its plans for a manned Mars mission in an October report, which centered on a three-phase project that would see missions poking out ever farther into the space between Earth and its red neighbor before culminating in an actual landing.

ASAP's report recognizes that NASA realizes it needs to develop technologies
1 Solar Electric Propulsion 
2 Deep Space Habitats

That sounds optimistic and all, and it's true that NASA is already hunting down promising landing sites and working hard to develop some form of real-life space hibernation. Folks outside NASA are even getting involved in helpful efforts, as in the case of the University of Arizona's Martian greenhouse project. But ASAP suggests that NASA's vague guesstimates won't do much to sway an American political environment that's not as committed to the space program as it used to be.

current budget for its Exploration Systems Development division

Both NASA managers and "industry partners" have expressed interest in continuing to operate the station until 2028 or beyond, ASAP notes, and "unless NASA were to be given a large increase in its appropriations, it is possible that continuing the ISS past 2024 may delay the Journey to Mars due to limited funding."

This makes the costs for ISS something that must be passed on to the private sector....

But the report misses a very important mars element in this next image.

Re: JPL Mars mission proposal

SpaceNut,

We should focus on getting there first.  A landing can only occur after every other required component of the architecture has been developed and tested first.

Re: JPL Mars mission proposal

Deep space habitat already possible by modifying ISS and cargo modules, or a fresh Skylab II for SLS and Nuclear or Solar ION thrust already possible just needs to be built.

Was searching ofr other documents as it relates to using a deep space habitat for a venus mission I located a document for this topic.

Thanks, SpaceNut.  I needed a good laugh.

Re: JPL Mars mission proposal

All chuckling aside the topic of the chemical kick stage and pushing what we need ahead to mars with out the crew on board using SEP keeps coming up. The issues are launch sequence timing and what we need to have in the critical locations and when do we need it there and why....

Re: JPL Mars mission proposal

Of course any mission for man for mars will mean a need to go back home and that is the MAV or mars ascent vehicle

look out another 598 paged document

details for lander size is for crew size
numbers for 2 stage are on pg 212

Re: JPL Mars mission proposal

So what plan can we use to go to mars with a real rocket as the BFR starship is dead on orbit due to the tremendous refueling requirement.

Re: JPL Mars mission proposal

GPIM aka green fuels Ball Aerospace has successfully completed on-orbit testing of NASA's Green Propellant Infusion Mission
