Nasa to Build Next Generation Planet Hunter selects Instrument

Nasa to Build Next Generation Planet Hunter selects Instrument

NASA has selected a team to build a new, cutting-edge instrument that will detect planets outside our solar system, known as exoplanets, by measuring the miniscule “wobbling” of stars. The instrument will be the centerpiece of a new partnership with the National Science Foundation (NSF) called the NASA-NSF Exoplanet Observational Research program, or NN-EXPLORE.

The instrument, named NEID (pronounced “nee-id”), which is short for NN-EXPLORE Exoplanet Investigations with Doppler Spectroscopy, will measure the tiny back-and-forth wobble of a star caused by the gravitational tug of a planet in orbit around it. The wobble tells scientists there is a planet orbiting the star, and the size of the wobble indicates how massive the planet is.

The highly precise instrument, to be built by a Pennsylvania State University research group led by Dr. Suvrath Mahadevan, will be completed in 2019 and installed on the 3.5-meter WIYN telescope at the Kitt Peak National Observatory in Arizona.

Using NEID as a facility observatory instrument, astronomers will be able to search out and study new planets and planetary systems, as well as follow-up the discoveries of NASA’s planet-hunting missions Kepler/K2 and the in-development Transiting Exoplanet Survey Satellite (TESS). NEID will also help identify promising targets for future observations with the James Webb Space Telescope and the Wide-Field Infrared Survey Telescope.

“The NEID instrument is a critical part of NASA’s partnership with NSF; this state-of-art precision instrument will enable the community to search for new worlds using the WIYN Telescope," said Paul Hertz, NASA Astrophysics Division Director in Headquarters, Washington. “We look forward to many new discoveries that can then be further explored using NASA’s space telescopes.”

NEID was one of two concepts for an extreme precision Doppler spectrometer that were selected for a detailed six-month study by NASA in June 2015.

The name NEID is derived from a word meaning “to discover/visualize” in the native language of the Tohono O’odham, on whose land Kitt Peak National Observatory is located.

NASA and NSF established a partnership in February 2015 to take advantage of the full National Optical Astronomy Observatory (NOAO) share of the Kitt Peak telescope. The goal is to provide the science community with the tools and access to conduct ground-based observations that advance exoplanet science, and support the observations of NASA space astrophysics missions. Kitt Peak National Observatory is operated on behalf of NSF by NOAO. The NEID project will be managed on behalf of NASA’s Astrophysics Division by the Exoplanet Exploration Program Office at the Jet Propulsion Laboratory.

The NN-EXPLORE is implemented in two stages:
Stage 1 – Pre-commissioning (through Sep 2019)
EPDS Instrument Development
The cornerstone of the NN-EXPLORE partnership will be a new NASA-funded Extreme Precision Doppler Spectrometer (EPDS). The EPDS instrument will be installed as a facility-class instrument on the 3.5-m WIYN telescope, and it will be made available to the scientific community through the NOAO time allocation committee (TAC) process.

NASA has selected a Pennsylvania State University research group, led by Dr. Suvrath Mahadevan, to build the highly precise instrument. NEID will be completed in 2019 and installed on the 3.5-meter WIYN telescope at the Kitt Peak National Observatory in Arizona.

Guest Observer (GO) Program -
Simultaneous with the instrument development, NASA will manage an exoplanet-targeted Guest Observer program with existing instrumentation using NOAO share (40%, approximately 100 nights per year) of WIYN time.

Stage 2 Post-commissioning (Starting in Oct 2019)

After the EPDS instrument is commissioned in the Fall of 2018, the partnership will exploit the new asset and the time available on WIYN telescope to support NASA missions such as Kepler, K2, and TESS. With the focus on science observations, NASA will
1-Manage an exoplanet-targeted GO and guaranteed time program at WIYN with EPDS instrument and existing instrumentation on WIYN
2-Maintain a data management system to serve EPDS data products and make them available to the community.
3-Provide open community access to a cutting edge EPDS instrument for observations that support NASA missions.

Have we ever thought that there may be a reason why the planets are so far away .. and may not want to be found ..

what would be really scary is if out there is a species that is also looking and finds EARTH :)

It is indeed a curious fact to unfurl the covert mystery of the Universe.New info.Thank you.
