MRO 2.4-meter Telescope Director Dr. Eileen Ryan

Dr. Eileen Ryan presented a talk at the American Astronomical Society’s 223rd meeting on January 5-9 in Washington D.C. She spoke about the MRO’s 2.4-meter telescope and how it is being used to track and characterize Near-Earth objects. The talk may be viewed on the  AAS Archive Press Conference Webcasts.

Dr. Ryan also addressed an international community (with representatives from ESA, DLR, Russian Academy of Science, IAU, NASA, Canada, etc.) on January 13 in Boston at the Minor Planet Center, Harvard Center for Astrophysics. She summarized the project’s work in the field of detection, characterization, and mitigation of potentially hazardous objects. The meeting was for the “International Asteroid Warning Network” (IAWN), which is an offshoot of one of the agreements at the 2013 United Nations Committee on the Peaceful Uses of Outer Space.

MROI UT

MROI Unit Telescope arriving at the EMRTC at New Mexico Tech on November 1, 2013

The first MRO Interferometer (MROI) Unit Telescope (UT) arrived from Belgium at the New Mexico Tech (NMT) campus on Friday November 1st. The long awaited arrival of the telescope, a major milestone for the project, which has been more than 15 years in the making. The crate containing the telescope was opened on Monday, November 4th at the Energetic Materials Research and Testing Center (EMRTC) and the telescope will be stored there until it is transported to the Telescope Receiving Facility, part of the MRO visitors center and maintenance facility (VCMF) on the Magdalena Ridge at the end of February, 2014.

The MROI will be a ten-element imaging interferometer operating at visible and near-infrared wavelengths, between 0.6 and 2.4 microns with baselines from 7.8 to 340 meters.

The MROI UT is a movable unit made up of the telescope mount, optics, enclosure and ancillary systems required for routine operation. The telescope mount, designed and constructed by AMOS in Leige, Belgium, is an elevation over elevation design with a fixed output beam implemented using only three mirrors. The telescope will be housed in an enclosure, designed by EIE of Mestre, Italy, features a rigid frame to support the telescope mount during relocation and a unique low profile dome and shutter to allow the telescopes to be placed in very close proximity without obscuring the field of view of an adjacent telescope.

Ancillary systems included within the UT structure are a “fast tip-tilt” system, designed by the University of Cambridge, which corrects for first-order atmospheric distortions, an automated alignment system that aligns the telescope with the delay lines in the beam combining facility, a wide-field finder telescope, and controls and network infrastructure.

Further work will be carried out at the Telescope Receiving Facility section of the VCMF. The Receiving Facility will mimic the foundations of the array, cooling systems, and various other external systems required for the telescope mount to function, including a pared down version of the enclosure. The Receiving Facility will allow the engineers to test the telescope mount to confirm its functions are working properly and help to integrate it with other systems of the MROI. These tests are expected to be complete by the beginning of Summer, 2014.

The technical and scientific goals are to produce model-independent images of faint and complex astronomical targets at resolutions over 100 times that of the Hubble Space Telescope.

Dr. Michelle Creech-Eakman has been working for years on a project of astronomical proportions and she recently gave a TEDxABQ talk to a packed Popejoy Hall at University of New Mexico (UNM) in Albuquerque about this ambitious project and its unmatched capabilities.

Dr. Creech-Eakman’s talk, “The Magdalena Ridge Observatory houses technology that will change our understanding of the universe”, described the array of ten telescopes that is being constructed on Magdalena Ridge. Creech-Eakman is Chair of the Physics Department at New Mexico Tech (NMT) and Project Scientist for the Magdalena Ridge Observatory Interferometer (MROI).

TED, a prestigious national nonprofit devoted to Ideas Worth Spreading was created in 1984 as a conference to bring together people from the three worlds of Technology, Entertainment, and Design (TED). In addition to two annual conferences — the TED Conference and TEDGlobal — TED includes the award-winning TED Talks video site, the Open Translation Project and TED Conversations, the annual TED Prize, and the TED Fellows and TEDx programs.

In the words of the TED organization, “The TEDx program gives communities, organizations and individuals the opportunity to stimulate dialogue through TED-like experiences at the local level.”

The array of telescopes that is currently being constructed on Magdalena Ridge “will have three hundred times the resolution of the Hubble telescope”, said Dr Creech-Eakman during her presentation. She explained the science of Interferometry, the combining of multiple beams of lights to create a single image, pointing out that “we all carry an interferometer around with us at all times in the form of your own two eyes”. She also explained how recent cuts in Federal funding to scientific projects have placed the completion of the Interferometer in jeopardy as she called for public support for funding to complete the project.

“The impact of the present funding squeeze on science projects is devastating” said Dr Ifan Payne, Program Director for the Magdalena Ridge Observatory, “It is so important to be able to participate in a public forum such as this and to have the opportunity to explain the importance of our science, the positive impact that the project has on the economy of the state, the effect that funding cuts have had on our ability to complete the construction of the MROI, and why, therefore, the need to seek alternative participation”.

Speaking of her experience of standing in front of a packed Popejoy Hall, Dr. Creech-Eakman said, “I’ve been teaching for many years so standing up in front of people and speaking about these concepts isn’t new to me, but at TEDxABQ, the audience was a lot bigger than I’m used to. They were so interactive and responsive, which brought a whole new dimension to the talk that it never had in rehearsal.”

“We’re all made of star stuff,” explained Dr. Creech-Eakman during that talk, “and that’s pretty incredible if you think about it. That’s why we’re building this interferometer: So we can learn more about the stars.” And therefore about ourselves. Which is why, she concluded, we should all be interested in seeing the interferometer completed, even though we may not all be astronomers.

On Saturday, August 10th, the Magdalena Ridge Observatory hosted a star party as part of the global International Starry Night Event. Coinciding with the Perseid Meteor shower, events were held around the world as part of the first International Starry Night, a celebration of starlight. Despite the non cooperating weather, 111 registered guests attended, along with MRO  staff and volunteers  from the New Mexico Tech (NMTAstronomy ClubNMT Physics Department, Langmuir LaboratoryNMT Board of RegentsNMT President, NMT Cabinet, and the Socorro High School Golf Team.

Tours of the 2.4-meter Telescope and the Interferometer were provided for guests by the MRO staff. Langmuir Laboratory and the NMT Physics Department representatives talked about the lightning research conducted on the mountain including the lightning mapping array, imaging of triggered lightning strikes, and instrumentation that is launched on balloons to measure electric fields.

Judging by the success of this inaugural event, the International Starry Night Event looks set to become an annual event in the MRO calendar.

MRO and Cavendish Laboratory engineers inspect the delay line trolley at the MRO laboratory.

On June 28, 2013  the first delay line trolley, built by the Cavendish Laboratory team at Cambridge University arrived in Socorro, NM for site acceptance verification tests and installation at the Observatory on Magdalena Ridge. The arrival of the trolley is a major milestone for the project because the Delay Line System is one of the essential subsystems of the Interferometer. As part of the beam train system, the delay line is responsible for correcting path delay between telescopes due to the different locations of the telescopes and from atmospheric turbulence. Such corrections are difficult to make as they must be done precisely and in real time.

Following delivery from the University of Cambridge the trolley has been reassembled and placed on its track at MRO laboratory on the New Mexico Tech campus. Initial functionality tests  have shown to be successful. Performance tests will be done in the next few weeks and the trolley is expected be taken to the Magdalena Ridge in early Fall for site acceptance tests.
