The overlapping observing coverage of the US-ELTP provides US astronomers with unfettered all-sky access from the Giant Magellan Telescope in the Southern Hemisphere and the Thirty Meter Telescope in the Northern Hemisphere. The timezone separation between the sites will increase the system’s capabilities for time-domain astrophysics.
TMT Project Manager Fengchuan Liu and Education, Outreach, and Broader Impacts Manager Yuko Kakazu gave presentations at the International Astronomical Union Asia-Pacific Regional Meeting (APRIM 2023) held from 7–11 August, in Koriyama City, Fukushima Prefecture, Japan.
The Thirty Meter Telescope is shown at a very low elevation angle. The segmented primary mirror reflects the Milky Way and convex secondary mirror. The tertiary mirror in the center of the primary mirror is oriented to send light to the Wide Field Optical Spectrograph, the gray structure located on the right side of the image. The left and right instrument platforms are seen and the dark blue adaptive optics enclosure is seen on the upper left on the instrument support structure.

Stylized view of the Thirty Meter Telescope with the telescope tube structure suppressed to highlight instruments and the segment handling system. On the far side of the segmented primary mirror is the adaptive optics enclosure in blue that supports the MODHIS First Light instrument on top (also in blue, inside the safety rails). The charcoal colored structure immediately to the left of the adaptive optics system is the telescope optics Alignment and Phasing System (APS). The tertiary mirror in the center of the primary mirror is oriented to send light to the Wide Field Optical Spectrograph, the light gray structure located on the instrument platform on the right foreground of the image. At the rear right is the part of the mirror segment handling system that transfers segments up and down to the observatory floor and on and off the segment handling system above the primary mirror (not shown).

Overview showing WFOIS instrument ...
The Thirty Meter Telescope is shown oriented straight up to the zenith viewed from behind the telescope tube, the telescope tips away to the back of the image to lower elevations. The segmented primary mirror reflects some of the segment handling system and the four mirror cleaning arms can be seen around the circumference of the primary mirror. The two instrument platforms are seen with the light blue adaptive optics enclosure on the platform on the right of the image. Attached to top of the adaptive optics system is the MODHIS instrument on top, shown in dark blue, the IRIS instrument beneath, seen as gray, and on the side port is a commissioning instrument, also shown as gray. The tertiary mirror in the center of the primary mirror is oriented to send light to the Wide Field Optical Spectrograph, the light gray structure located on the instrument platform on the left side of the image. The foreground structure is part of the mirror segment handling system that transfers segments up and down to the observatory floor and on and off the segment handling system above the primary mirror. Segment exchanges take place with the telescope oriented to the zenith.

The Thirty Meter Telescope is shown at an elevation angle of about 45 degrees. The segmented primary mirror reflects some of the telescope’s upper tube structure. The two instrument platforms are seen and the dark blue adaptive optics enclosure is seen in the foreground atop the instrument support structure. Attached to top of the adaptive optics system is the MODHIS instrument on top, shown in dark blue. The charcoal colored structure immediately alongside the adaptive optics system is the telescope optics alignment and phasing system (APS). The tertiary mirror in the center of the primary mirror is oriented to send light to the Wide Field Optical Spectrograph, the gray structure located on the instrument platform to the rear of the image.
