BITSE is a project of balloon-borne experiments for a next-generation solar coronagraph developed by a collaboration with KASI and NASA. The coronagraph is built to observe the linearly polarized brightness of solar corona with a polarization camera, a filter wheel, and an aperture door. For the observation, the coronagraph is supported by the power distribution unit (PDU), a pointing system WASP (Wallops Arc-Second Pointer), telemetry & telecommand system SIP (Support Instrument Package) which are developed at NASA's Goddard Space Flight Center, Wallops Flight Facility, and Columbia Scientific Balloon Facility. The BITSE Command and Data Handling (C&DH) system used a cost-off-the-shelf electronics to process all data sent and received by the coronagraph, including the support system operation by RS232/422, USB3, Ethernet, and digital and analog signals. The flight software is developed using the core Flight System (cFS) which is a reusable software framework and set of reusable software applications which take advantage of a rich heritage of successful space mission of NASA. The flight software can process encoding and decoding data, control the subsystems, and provide observation autonomy. We developed a python-based testing framework to improve software reliability. The flight software development is one of the crucial contributions of KASI and an important milestone for the next project which is developing a solar coronagraph to be installed at International Space Station.

공개된 자료들을 바탕으로 NASA의 표준 착화기 NSI-1,2,3의 간략한 성능규격 비교와 함께 NSI에 연결되는 전기 커넥터의 규격을 비교하였다. NSI-1,2에 연결되는 커넥터의 규격은 MSFC-40M38298과 MIL-DTL-26482, series1이며, NSI-3에 연결되는 커넥터의 규격은 MIL-DTL-38999, series3이다. 전체적인 내환경 성능은 낮음에서 높음 순서로 MIL-DTL-26482, series1/MSFC-40M38298/MIL-DTL-38999, series3 이다. 특히, 고충격, 고진동 환경에서 착화기를 사용하여야 한다면 NSI-3의 커넥터 규격인 MIL-DTL-38999, series3의 커넥터를 사용하는 것이 적절할 것이다.

Objectives: Sciatica is a musculoskeletal pain sensed in the leg along with the distribution of the sciatic nerve, which is sometimes accompanied by low back pain and is most commonly caused by a disc herniation. In the Unani system of Medicine, Irq-un-Nasa (Sciatica) is defined as the pain which starts from the hip joint and descends towards the foot. It is a type of Waja-ul-Mafasil which is developed due to the accumulation of Khilt-e-Dam or Khilt-e-Balgham ghaleez in the hip joint. The conventional system of Medicine offers several medications and surgeries to manage sciatica with limited clinical evidence of effectiveness. These cases aim to provide insight into the effects of Fasd (Venesection) in Irq-un-Nasa. Case Presentation: Fasd was performed in the saphena minor vein of two clinically diagnosed patients with sciatica after the initial assessment. Two sittings of Fasd, once a week in each patient, were performed, followed by telephonic assessments for two months. The intensity of sciatic pain reduced with subsequent sittings of Fasd, and there was no recurrence of any symptoms and signs again during complete follow-up. Conclusion: Based on the results of the present case report, it appears that such cases of Irq-un-Nasa can be managed with Fasd, and the quality of life of such patients can also be improved.

적외선 우주배경복사 관측실험 (Cosmic Infrared Background ExpeRiment, CIBER) II는 2009년 2월 25일 화이트샌드 미사일 기지에서 NASA 사운딩 로켓에 탑재, 발사된 CIBER I의 후속 프로젝트이다. 독립적인 Imager 2 대와 Spectrometer 2 대로 구성된 CIBER I과 달리 CIBER II는 하나의 주경과 부경으로 구성된 광학계를 4 대의 Imager가 beam splitter를 이용하여 관측하게 구성되어 있다. CIBER II는 NASA에서 공식적으로 승인되었으며, 한국천문연구원과 한국기초과학지원연구원이 미국 NASA/JPL, Caltech 및 일본 ISAS와 국제 공동으로 개발할 계획이다.

Recent studies of single wall carbon nanotube (SWNT)/polyimide nanocomposites indicate that these materials have a potential to provide the combination of structural integrity and sensing/actuation capability. This study shows the effect of the SWNT type and concentration on the dipole orientation and piezoelectric properties of the electroactive polymide nanocomposites using a thermally stimulated current (TSC) spectroscopy. These nanocomposites exhibit very thermally stable piezoelectric properties up to $150^{\circ}C$. This presentation will highlight the dipole orientation and electroactive characteristics of the SWNT/polyimide nanocomposites and discuss their potential multifunctional aerospace applications.

NASA and Korea Astronomy and Space Science Institute (KASI) have been collaborated to develop the Space solar coronagraph instrument to detect the solar wind speed and corona temperature. As an intermediate stage, BITSE is the Balloon-Borne instrument to prove our proposed technical method which uses a polarized light in 4 different bandwidth wavelengths. In the presentation, the optical design based on the requirements, tests and alignment process for integrating the system are discussed.
