Moon/Mars Exploration Trying to ensure that CSA doesn’t get left behind in the car
The Issue • ESA has Aurora - Humans to Moon and Mars • EU Supporting ESA, building relationship with Russia - potential EU/Russia joint human missions in 2008 onwards, using Soyuz TMA. Discussions of a joint ESA/Russian human space capsule. • US Adopted Vision for Space Exploration • China: human missions • India: will have robotic missions to the Moon • Sample return missions to Mars starting in 2011 to 2014 timeframe • Even Japan is now looking at human missions
Evolving Fast • ESA has initiated a Humans to Moon Lunar Roadmap process • NASA is accelerating CEV schedule • Bending metal on CEV next year, single source • Probable reductions in Earth Science • Probable reductions in Planetary Science • Certain reductions in ISS • Possible reduction of international cooperation and use of industry • Both EU and US scientists are starting to have doubts about robotic missions, on cost/science and cost/impact grounds. Good missions may be $1-$2B, similar to per-person cost for human missions.
Problem: we’re behind • Now too late to concentrate on small robotic missions if we want to be visible, or have any chance of retaining HQP – NASA no longer even lists robotic missions as milestones in roadmaps • NASA wanted input last June from all agencies, if they wanted to collaborate on Moon/Mars. No new major CSA areas identified at a strong level. • (Just) Canadian Robotic Mars missions in 2011 or later will not cut it - we’ll all be working for ESA and NASA by then! • We’re the only country, apart from Russia, which hasn’t refocused our space agency to human space exploration. Indeed, we’re going the other way. • But we have a combined human and space science-based exploration thrust? Maybe time to move Space Exploration outside Space Science?
Key point of plans: No Money • Getting humans into space isn’t about more money • Asking for more money just increases chances agencies get rejected, as we’ve seen with CSA • US Space Policy already demonstrated to be hard to kill, last year, in Senate vote on budget - works by shifting focus and funding, with minimal funding injections • CSA doesn’t need more money - needs to prove it can retain it’s budget as the SSRMS, Canadarm, and Radarsat 2 come to completion. Can we fit in with new CSA structure and retain human spaceflight and exploration? • Focus CAN including working on human missions to Moon and beyond, with no extra budget!
Interesting Points • ESA seems to be ahead on the CEV! Experience with ATV and ARD, and relationship with Russia. • NASA and Boeing imply ESA ATV concept crucial to CEV, Lock-Mart actually seems to be using ATV-H in their CEV design. • CEV requirements closer to Gemini (designed by Canadians) and Soyuz, not Apollo. • Goddard has Lunar lead, not JPL: Exploration-driven R&D better for science, long-term, than direct science-driven R&D. • Given 10 year Dev cycles, Canada has to move very fast (ESA tested ARD in 1998, and NASA needs ESA). • However, if we devote enough budget, no reason we can’t deliver $1B+ contribution over 20 years. $50M/year. Enough for a Canadian to go to the Moon.
Human Missions • Extensive communication required for scientific field exploration • Mission operations requires complex modalities in Human missions • Missions high power, high mass, high margin: communications operate in a far less constrained environment • Large number of interacting systems: cannot afford to add extra communication protocols or other technologies to multiple small hardware ($B’s/pa spent by COTS R&D community on protocol and comms). Less buy-in cost, more use of all industry possible • Human Space Exploration is not Robotic Space Exploration • Human Space Exploration is not Human LEO Spaceflight Reliability is the single most important requirement
Human spaceflight EASIER • Not such a hard road to follow: • Having humans in the loop requires many systems that operate in human-survivable environment. Low TVAC requirements, large masses allowed, only rad to worry about. • Systems can be cheap - some NASA suppliers spend less than $1M to fly hardware on ISS, with a few months development time (sensor networks) • Lunar missions are actually WAY easier, environmentally, than the conditions we face for S/C like Anik F series!
Choosing our Partners • We can’t sit on the fence • NASA maybe isn’t the best choice as our only choice • ESA ahead on many technologies, including CEV systems, and far more interested in having critical infrastructure development than NASA • Possible short-term ESA and CNSA human spaceflight options. NASA ones far off in the future.
Canadian Tech Possibilities • Life Support • Mars Environment • Spacesuit Technology • Plant Growth • Drilling and Sample Handling • Communications (hardware and protocols) • Computing (hardware and software) • Navigation • Imaging • Analogues • Robotics
Communications • Communications rapidly growing to become Canada’s biggest industry • Only country to supply NASA with a Criticality One system (comms) to ISS, apart from Russian (eg, life-critical, not just mission critical) • Involved with key ESA discussions on communications - EU expected to spend millions of Euros per year on technologies derived from Canadian concepts, but with no Canadian involvement. • Canada has the best surface wireless comms system for Moon and Mars • Canada provided the comms antenna for Apollo (start of SPAR!) • Canadians designed most of DSN, for NASA (after leaving Arrow project) • Mars and Moon comms relay satellites would be cheap, inside our expertise, and would multiply returned science data by a minimum of 100 times (probably in excess of 1000 times). • V-band, W-band, Optical comms are strengths • EMS, Xiphos, ComDev, SFU, UTIAS, MDA, Bristol Aerospace • Cheap, but high impact.
ESA Concept ESA-Industry Wireless WG Scenarios Appropriate for Lunar/Mars Missions cont. • Several appropriate opportunities for SS RF Wireless ESA SFU ESA ESA NASA ESA SEA Ltd. Concept ESA Concordia SFU Concept
Spacesuit Tests – Cheap, Visible! • Collaboration between NASA HMP, SFU, and Hamilton-Sundstrand • On-board Canadian • Comms and Computing • Next-generation voice control • Remote Control • Location tech • Range of head-mounted displays Camera (Trish Garner, SFU, Canada)
Building our own small human spacecraft: Spacesuits • High visibility (most other options aren’t) • Space Comms/Computing - Canadian Strengths • Canada already demonstrating startling improvements in situational awareness in suit design, with Hamilton-Sundstrand/SFU collaboration, at MarsCanada. • Strong diving suit and life support knowledge in Canada, with Western Canada support • Canadian Naval submarine expertise closely related. • SFU and DCIEM/DRDC physiology knowledge and facilities • Major bit is mechanisms: EMS, MDA • Requires integration: MDA • Can partner with US, ESA, Russians, China • Human roving vehicles a bigger spacesuit, though maybe too expensive.
Large Rovers on Mars and the Moon (Mars Institute / SFU) – Many on-board Techs needed
Greenhouse for Mars: TM, TC, and Autonomy (Guelph / SFU / Mars Institute / SpaceRef Inc.) – ESA and NASA want Guelph already
Biology • U. Guelph: Mars Greenhouses - critical life support for extended Moon/Mars missions • Strongly recognized by Canada • World leaders in Aerospace Physiology (Roberta Bondar, Andrew Blaber) • Extreme Physiology Program at SFU (Braham, Blaber) • Canada are leaders in Telemedicine (including major CRC projects)
Computing • Canada (EMS Technologies) a world leader in processors that are rad-hardened to Mars/Moon rad environment • EMS / Telesat build and operate systems that survive in GEO for 20 years! • Goes hand in hand with Comms • Human mission requirements far easier than robotic missions. • Big impact, and maybe visible?
Navigation • Precise landing critical, as demonstrated by NASA robotic missions to Mars - need to go EXACTLY to where the science is located. • Surface traverses require detailed mapping and navigation • Canadian LIDAR systems may be critical to this work • Only Issue: NASA and ESA developing their own.
Imaging • Human missions allow resources for high bandwidth connections • Canadian imaging systems such as SAR and Hyperspectral imaging are effectively impossible at robotic payload accommodation levels • POSSIBLE at human mission levels! • Highly useful for missions, as remote spotting of important outcrops, water, essential
Other Canadian resource tech • Drilling • Drilling important for sample recovery, but everybody is doing it, including robotics, but potential niche? We’ll need to work on it heavily if we want it. • Drilling totally different issue in human missions, and traversing often better than drilling (as can be seen in MER). But humans allow new ways to drill. • Resource Processing (ISRU) • NASA’s own studies have show that safe missions do not require ISRU, as orbit and return capability requires way more mass than ISRU saves for anything short-term. • However, benefits to large industry (SFU involved in potential mining applications of MarsCanada and emergency comms spin-offs, via NRC)
Analogue Studies • Require analogue studies for any robotic or human mission development • HOWEVER: • Too expensive for just science research • Only makes sense if it’s supporting exploration systems development (doing analogues properly will cost $10M/site over a few year R&D cycle) • Maybe we should do it, but have to think carefully • Maybe environmental analogues for small systems tests (Guelph, SFU, DCIEM/DRDC, small field trips) may make more sense. SFU-type vehicles. • BUT: • Has been high visibility, and it’s getting our tech in people’s face, and producing impact.
Choices • Spacesuits and human rovers, including spacesuit comms computing, look promising • Involves life support • Cheap • High visibility • May be enough for a Canadian to get to fly to the Moon • Even components: high visibility and interesting • Human Support Robotics critical • Imaging leaps right out as well, but maybe a component of suits, or even human rover vehicles? • Comms, but aimed at Mars, or maybe Lunar surface? • Drilling and ISRU possible, if we can get a lead back • Others may be promising, but a tougher sell.
Costs • Beagle Class Lander to Mars: $200M • Comms Relay to Mars, supporting human mission comms / Mars Sample Return, and Canadian imaging tech: $200M • Spacesuit: $200M (probably $1-$5M a piece) • Spacesuit and spacecraft components: $1M-$10M • Imaging systems: $1M-$50M • Generic Physiology / Plant Growth / Telemedicine: $1M-$50M each • Analogue support vehicles (non-Arctic): $1M-$5M • Soyuz launches for tests: $100M (ISS time?) • So, say, $1B over 20 years could buy a lot, and make Canada a world leader in human space exploration. 15% of CSA budget. • If we don’t, everybody else can afford it anyway
