1. i-INSPIRE and Related Instrument and Spacecraft Projects at the University of Sydney Iver Cairns and Joe Khachan * 1.i-INSPIRE 2.Instruments & devices (thrusters) developed for payloads & projects 3. QB50 and INSPIRE-2 4. Status & Summary * and C. Betters,J. Bland-Hawthorn, L. Fogarty, J.Funamoto, S.Leon-Saval, A.Size, X.Wu

2. 1. Status of i-INSPIRE : initial – INtegrated SPectrograph, Imaging, and Radiation Explorer An Australian sole University space project To develop capability & interest (first images of Aust. from Aus.SC?) Demonstrate:  spacecraft d/b/t/o capability  novel spectrograph for space, Astro, Earth observations …  global radiation & space weather  spectrograph radiation testing  imaging for location, rotation, & PR Launch with US startup InterOrbital Systems but date unknown.

3. i-INSPIRE Building & Testing Breadboard Flat Sat test: July 2012 PCB Flat Sat test: 4 Sept 2012 Integration tests: 18-25 Sept 2012 Balloon launch: Adelaide, 25 Nov. 2012, Project Horus. Radio licenses – provisional (IARU) Educational /Scientific Declaration & Overseas Launch Certificate: underway (started July 2012). 3

4. Balloon launch 25 November 2012: near Adelaide with Project Horus 4

5. 2. Instruments & Devices Originating with i-INSPIRE payload –Nanospec – A photonic spectrograph –Radiation counter –Imaging camera Plasma thruster Plasma wave receiver..... Dedicated payload QB50 or other QB50 or other

6. i-INSPIRE instruments (a) NANOSPEC – A photonic spectrograph (b) Geiger Counter Imaging Camera (commerical off shelf)

7. a) Nanospec [C. Betters, S. Leon-Saval, L. Fogarty, & J. Bland-Hawthorn]

8. Nanospec details Essentially diffraction limited in Visible (400-715 nm). Measured resolving power (/) of R >1400. Spatial resolution looking at Earth is ~40km 2. (note: there are no coupling optics yet) –Simple field of view from single mode fibre. Relatively cheap construction –<< $1000 total cost for prototype [C. Betters, S. Leon-Saval, L. Fogarty, & J. Bland-Hawthorn]

9. (b) Radiation Counter for i-INSPIRE < 14 g, about 5 x 2.5 x 1 cm Measures radiation levels... also helps constrain orbit & location [J. Khachan]

10. (c) Plasma Thruster for propulsion, stationkeeping... –Invention documents agreed & signed with DSTO –DSTO license agreement signed –Patent application submitted ([J. Khachan – David Dall vital]

11. (d) Plasma Wave Instrument Thermal motions  thermal Langmuir waves  n e & T e Upper hybrid & whistler waves  B Well established for weakly magnetized space plasmas Idea: do Thermal Noise Spectrometry for constellation of cubesats  disentangle spatial & temporal variations of n e, T e, B for the ionosphere Space weather, SSA.... 11 [I.Cairns, J. Khachan, N. Wallace, R, Maj, et al.]

12. 3. INSPIRE-2 Passed Critical Design Review (CDR). U. Sydney: 2 U spacecraft with QB50 Langmuir Probe package Includes: Nanospec, Plasma Thruster, Radiation Counter, active control (magnetotorquers), wave experiment, 12

13. 4. Summary & Status i-INSPIRE – designed & balloon-tested to 27 km –being re-integrated for full testing & flight (IoS date?) –cubesat version (c-INSPIRE) next highest priority. Instruments & Devices (currently main effort) –Nanospec & Radiation Counter in dedicated payload for Delta-V, QB50, or other opportunities –Plasma thruster – looking for opportunities –Plasma wave receiver – QB50, SSA. & other opportunities INSPIRE-2 passed QB50’s Critical Design Review (CDR)... 2016 / 2017 launch.
