2 Appropriate Sayings Don’t wait until problems accumulate and cause a lot of trouble before trying to solve them from “Contract on a Seasonal Basis” In this world, things are complicated and decided by many factors. We should look at problems from different aspects, not from just one from “On the Negotiations” The world is yours, as well as ours, but in the last analysis, it is yours. You young people, full of vigor and vitality, are in the bloom of life, like the Sun at 8 or 9 in the morning. Our hope is placed on you form a talk at a meeting with students and trainees in Moscow

From Kurskaya Station in Moscow, I rode in a train to Tula, Where Vladimir met me. He drove us south on the M2 highway about 30km to the 2-lane P141 highway that we drove on for 100 km to join the M4 highway (Interstate quality) just southeast of Yefremov. Then we drove south on M4 through Voronezh to the graze site near the exit to Mozhayskoye, a distance of a little more than 400 km from Tula. M2 P141  Yefremov M4  Mozhayskoye M4

29 SEntineL1 for “Bolts out of the Blue”
NASA has put out a special call for ideas for planetary defense; I will submit this to them by their July 18th deadline Chelyabinsk showed that even asteroids as small as 15m can cause extensive damage There are several million NEA’s larger than 15m The surveys are finding less than 1% of these objects They are too small to observe at large distances, so They can only be seen when they pass near the Earth Since many have Earth-like orbits with periods near a year, it will be centuries before a large fraction of them could be found with current technology

31 Publications for Extending Human Exploration beyond the Moon’s Orbit
Article should appear in J. of Astronautical Sciences by year’s end Farquhar will give a presentation to William Gerstenmaier, NASA Associate Administrator for Human Exploration and Operations, in August, showing some of YOUR work Further information about our work will be presented at IAC in Beijing in September, and we will submit publications based on that work; the conference papers are due September 4

32 Ideas for Extending Human Exploration beyond the Moon’s Orbit
Servicing Space Observatories near Sun-Earth L2 was the original first suggested effort Now first missions will likely be to Earth-Moon L2 orbits, like we have been calculating Double Lunar Swingby Orbits, for transfers and for moving the line of apsides Phasing Orbit Rendezvous Interplanetary Transfer Vehicle Rendezvous with a Near-Earth Asteroid Ideas developed under International Academy of Astronautics (IAA) exploration working group International collaboration will be essential for the success of such a large effort

33 Work for Extending Human Exploration beyond the Moon’s Orbit
Our team has computed many good trajectories from the Earth to a 10,000 x 10,000 km Lissajous orbit, with return to the Earth at different optimized times from this orbit using a powered (S2) lunar swingby The next important step is to repeat the above for a periodic halo orbit about the Earth-Moon L2 point. Computing a quasi-periodic orbit about the Earth-Moon L2 point is not easy; we want to return to the same rotating frame X at the Y=0 plane crossing, with both Xdot and Zdot = 0, after two revolutions in the orbit. University of Arizona colleagues are trying to program Farquhar and Kamal’s 3rd-order theory in order to obtain better initial conditions for the task above. The next tasks will be to transfer from the Earth-Moon L2 orbits to a double-lunar swingby trajectory, or to a Sun-Earth L2 orbit, to allow reusable vehicles to line up departure asymptotes to go to near-Earth asteroids and to Mars. Others have publications on transferring between the different libration-point orbits that we need to study.

44 Forestry from Space This is a new project for the laboratory that will begin in September It will start as a small project, funded by KinetX There is strong interest in this project in Canada Canada and Russia have the largest northern forests in the world Therefore, this is a good project for international collaboration between the two countries In addition, Alfred McEwen at the University of Arizona is an expert on space sensors that could be used on this project This would strengthen MIEM/HSE’s collaboration with U. of AZ Perhaps Prof. McEwen could travel to Moscow with Roberto Furfaro in early September?

46 Meeting at our Laboratory
Minutes of 2013 July 4 Meeting at our Laboratory By July 25, 2013, prepare and agree to the terms of reference for the project “Forestry from Space”. By 15 August 2013, prepare proposals on the participation of the scientific team at the Laboratory Project “Forestry from Space”. By August 27, 2013, agree with the company KinetX (USA) draft contract to conduct applied research in the field of sensor or set of sensors mounted on the spacecraft to save the forests, fires and prevent the threat of pollution and other uses of forest protection

47 Statement of Work: Forestry from Space (1)
Description: We are interested in what services could be provided by a sensor or set of sensors in space for forestry industries. This would include (but not necessarily limited to) services in the following areas: Forest health State of combustibles and fire risk Identification of start time and location, and status, of forest fires Identification of insect infestation Identification of illegal logging operations (cutting down trees) Keep in mind the later possible use of the data for agriculture Assumptions: Satellites will be in a low-Earth orbit; 700 km to 1100 km. Circular orbits are preferred, but elliptical orbits might be considered. The orbital inclination should be high enough to cover all forested areas of interest [could be, but not necessarily, polar (incl. 90) or sun- synchronous (incl. 97). Sensor types to consider: Infra-Red, Multi-Spectral, Hyperspectral. Start with existing sensors with high TRL. If products could be vastly improved by modifications to existing sensors, include that in your work. What resolution (spatial, temporal, and wavelength) are needed to accomplish the goals above? The orbital and sensor requirements would derive from these goals. Perform analyses for a) one satellite b) multiple satellites c) constellation of satellites. Perform trade studies to optimize the distribution of satellites. Do not worry about how to get the data to the ground, but make some reasonable calculations of the amount of data that would be generated.

48 Statement of Work: Forestry from Space (2)
Deliverables: A document containing the following: A description of the analyses done A list of specific products that could be provided for forestry in general. Include: Sensor type and specification used to generate data for product Required work to generate the necessary information from the raw data The satellite, or satellite configurations, needed to gather the data The orbital characteristics required to gather the data Any suggested improvements to sensors that would allow developing additional products or enhance existing ones List of potential customers for the data in Russia Recommendations for further analysis and for steps forward for discussions with customers. Weekly status (can be conference call; does not need to be written) Schedule: (2013) Project kick-off: 27 August (Tuesday) – [more likely 30 August (Friday)] Status Meeting 1: 15 October (Tuesday) Status Meeting 2: 20 November (Wednesday) Final Delivery and Review: 20 December (Friday) This project, generating products of use to a wide range of companies in Canada, Russia, and elsewhere, should put our Laboratory on a stronger financial basis than can be expected from planetary defense or human exploration. The potential is huge.

54 Interplanetary Ideas for Microsatellites
NESTRA is interested in ideas for how their microsatellites might be used in an interplanetary mission that would generate worldwide interest; they are willing to fund research to develop such missions. The active comet Wirtanen will pass only 0.08 AU from Earth in December 2018; we are suggesting to NESTRA that we could design a mission to that comet with several of their small spacecraft, to study for the first time the 3-dimensional structure and composition of the coma of this comet. The next two slides show the low-energy orbit that can reach the comet, and return to the Earth. Another idea would be to land 3 or more microsatellites, with seismometers, on the surface of an easily accessible near-Earth asteroid. Another microsatellite would crash into the asteroid; the seismometers would then measure the shock wave arrival times and structure at each site, from which the asteroid’s internal structure could be determined. If NESTRA isn’t interested in these ideas, other microsat manufactures, in France, Russia, and perhaps elsewhere, might be.
