Mission Objectives
The primary objective of the SIMP mission is to:
- Measure the proper motions of 1 billion stars in the Milky Way
- Determine the kinematics and dynamics of the Milky Way
- Search for and characterize extrasolar planets
- Study the structure and evolution of the Milky Way
Mission Design
The SIMP spacecraft is equipped with the following instruments:
- Near-infrared camera: To measure the positions and motions of stars
- Spectrometer: To measure the radial velocities of stars
- Astrometric telescope: To measure the parallaxes of stars
Launch and Operations
The SIMP spacecraft was launched in 2022 and is expected to operate for 5 years. The mission is expected to produce a wealth of data that will help astronomers to better understand the Milky Way.
Essential Questions and Answers on Sondage Infrarouge de Mouvement Propre in "MISCELLANEOUS»UNFILED"
What is the SIMP survey?
SIMP (Sondage Infrarouge de Mouvement Propre) is a photometric survey that measures the proper motion (movement across the sky) of stars in the Milky Way galaxy. It is conducted using the VISTA telescope at the Paranal Observatory in Chile.
What are the goals of the SIMP survey?
The primary goal of the SIMP survey is to create a detailed map of the Milky Way's stellar populations, including their ages, metallicities (the abundance of elements heavier than helium), and kinematics (motions). This information will help astronomers better understand the structure and evolution of our galaxy.
How does the SIMP survey measure proper motion?
SIMP measures proper motion by comparing the positions of stars in two different epochs, typically separated by several years. The difference in position between the two epochs provides a measure of the star's proper motion.
What is the wavelength range of the SIMP survey?
The SIMP survey is conducted in the near-infrared wavelength range, specifically in the Y, J, and H bands (1.0-1.8 microns). This wavelength range is sensitive to the light emitted by cool stars, which are the most common type of star in the Milky Way.
What is the expected duration of the SIMP survey?
The SIMP survey is expected to last for several years and is currently ongoing.
Final Words: The SIMP mission is a major undertaking that will provide valuable insights into the structure and evolution of the Milky Way. The data from the mission will be used to study a wide range of topics, including the kinematics and dynamics of the Milky Way, the search for and characterization of extrasolar planets, and the study of the structure and evolution of the Milky Way.
