  • NASA released a solicitation for proposals for next generation science instrument(s) that will harness the unique capabilities of SOFIA, the Stratospheric Observatory for Infrared Astronomy.

    SOFIA is a Boeing 747SP aircraft that carries a 100-inch telescope and science instruments to 38,000- 45,000 feet. At these altitudes, it is above more than 99 percent of Earth’s atmospheric water vapor, thereby opening up wavelengths for astronomical observations not available from the ground. Unlike most space missions, its scientific instruments can be exchanged between flights to accommodate changing science requirements and to incorporate new technologies.

    The science instrument selected for SOFIA in 2016 is currently being built by a team at NASA’s Goddard Space Flight Center. The High Resolution Mid-InfrarEd Spectrometer (HIRMES) will help researchers determine the location of the raw materials that are the building blocks of life and to better understand how they help planetary systems, like our own solar system, evolve. It’s scheduled to fly on SOFIA in 2019.

    SOFIA’s newest instrument, regularly used for observations from 40,000 feet, is an infrared camera and polarimeter, which can be used to map celestial magnetic fields. It’s helping researchers better understand how stars form, how gas cools in the interstellar medium, and how magnetic fields are creating stellar winds around black holes.

    • 美国NASA为2.5米红外机载天文台(SOFIA)挑选下一代光谱仪--高分辨中红外光谱仪(HIRMES)。2019年春天,HIRMES研制完成,投入使用。 A team from NASA’s Goddard Space Flight Center in Greenbelt, Maryland, has been selected to develop a new, third-generation facility science instrument for the Stratospheric Observatory for Infrared Astronomy, SOFIA. The principal investigator, Samuel Harvey Moseley will lead the team to develop the High Resolution Mid-InfrarEd Spectrometer (HIRMES). The team consists of co-investigators from Space Dynamics Lab, Precision Cryogenic Systems, Inc., University of Michigan, University of Maryland, Smithsonian Astrophysical Observatory, Johns Hopkins University, Space Telescope Science Institute, Cornell University and University of Rochester. Moseley and his team will construct HIRMES over the next two and one-half years with flights on board SOFIA slated for spring 2019. At that time, this unique research asset will also be made available for use by the larger astronomical community. “HIRMES will help researchers determine the location of the raw materials that are the building blocks of life and how their position within the interstellar medium helps planetary systems, like our own solar system, evolve,” said Hashima Hasan, SOFIA program scientist at NASA Headquarters in Washington, D.C. “HIRMES builds upon Moseley’s long history of superior instrument design. Included among his many achievements is the development of the microshutter arrays for the James Webb Space Telescope’s near-infrared spectrometer.” The HIRMES spectrometer is optimized to detect neutral atomic oxygen, water, as well as normal and deuterated (or “heavy”) hydrogen molecules at infrared wavelengths between 28 and 112 microns (a micron is one-millionth of a meter). These wavelengths are key to determining how water vapor, ice, and oxygen combine at different times during planet formation, and will enable new observations of how these elements combine with dust to form the mass that may one day become a planet. HIRMES will provide scientists with a unique opportunity to study this aspect of planetary formation, as SOFIA is currently the only NASA observatory capable of accessing these mid-infrared wavelengths. Infrared wavelengths between 28 and 112 microns will not reach ground-based telescopes because water vapor and carbon dioxide in the Earth’s atmosphere block this energy. SOFIA is able to access this part of the electromagnetic spectrum by flying between 39,000 feet and 45,000 feet, above more than 99 percent of this water vapor. NASA anticipates soliciting proposals for the next (fourth generation) instrument on SOFIA in 2017. SOFIA is a Boeing 747SP jetliner modified to carry a 2.5-meter, 100-inch, diameter telescope. It is a joint project of NASA and the German Aerospace Center. NASA’s Ames Research Center in California’s Silicon Valley manages the SOFIA program, science and mission operations in cooperation with the Universities Space Research Association headquartered in Columbia, Maryland, and the German SOFIA Institute at the University of Stuttgart. The aircraft is based at NASA’s Armstrong Flight Research Center's Building 703, in Palmdale, California.

    • The Thirty Meter Telescope Project, in concert with its Scientific Advisory Committee (SAC), announces a call for white papers proposing design studies for new instruments, adaptive optics systems, or other technical developments that would significantly enhance the scientific capability of TMT beyond first-light. Individuals and teams comprising members of the TMT scientific/engineering community are invited to submit white papers. The proposed project should be placed in the context of the first-light TMT capabilities, which include the near-IR multi-conjugate adaptive optics system (NFIRAOS; overview, detailed description), the InfraRed Imaging Spectrograph (IRIS; overview, brief description), the Wide-Field Optical Spectrograph (WFOS; brief description) and the capabilities of other current and future observatories (e.g., JWST, TESS, EUCLID, LSST, WFIRST, and other ELTs) in the post-2025 era. White papers may address capabilities previously identified as priorities for TMT, which include high-dispersion optical spectroscopy, high-dispersion near-IR spectroscopy, multiplexed medium-resolution near-IR spectroscopy (presently considered for the IRMS instrument*; overview, brief description), extreme/high contrast adaptive optics/coronagraphy, mid-IR imaging and low-resolution spectroscopy, and high-dispersion mid-IR spectroscopy. However, the SAC welcomes submissions addressing novel areas or those which fall outside or between the existing scientific instrument requirements (TMT Observatory Requirements Document, Science Requirements Document). In September, 2017, TMT will initiate a design study for an adaptive secondary mirror (AM2) which may be available during TMT's early light. The AM2 would facilitate Ground Layer Adaptive Optics (AO enhanced image quality for wavelengths 0.4-2.5 microns) over a large fraction of the unvignetted telescope field of view (15 arcmin diameter). The AM2 would also enable diffraction-limited images at mid-IR wavelengths (3.3-27 microns), and thus would likely serve as the facility mid-IR AO system. Instrument concepts that would benefit from this capability, as well as those that would operate behind the NFIRAOS AO system (or a future NFIRAOS upgrade), are encouraged. All white papers will be reviewed by the SAC, who will recommend a subset for feasibility study funding by the TMT Project. Submitted white papers should provide a summary of the scientific goals and objectives of the proposed instrument development, a suggested instrument architecture, a brief description of the scope of work to be done to further develop the science case and study the instrument feasibility, a list of science and engineering team members, and should address the suitability of the proposal team for conducting the study. Innovative technologies may be highlighted. This is the first part of the process for identifying and developing the 2nd generation instruments. White papers should be no more than 10 pages in length, including figures and tables, and should be submitted to whitepapers@tmt.org no later than March 21, 2018. It is anticipated that SAC reviews of all submitted white papers will be completed during the second quarter of calendar year 2018. The SAC may request additional information from proposed study teams prior to completion of the reviews. Please address any questions to whitepapers@tmt.org. We very much look forward to receiving and reading your proposals! Sincerely, TMT SAC Co-chairs * The scientific justification for a multi-object near-IR spectroscopic capability remains very strong. Because of the expected date of first light and that the baseline MOSFIRE-based design for IRMS may not be technologically appropriate at that time, the project and the SAC welcome new ideas to provide this capability.
