InSight Mission
  گسیلان ِ اینسایت   
gosilân-e InSight

Fr.: InSight: Exploration interne par les sondages sismiques, la géodésie et les flux thermiques   

A NASA lander designed to study the interior of the planet Mars. It will be a stationary mission, in contrast to NASA's famous Opportunity, Spirit and Curiosity rovers. Staying in place is necessary for its major science goals, which include learning more about the Martian composition, and how tectonically active the red planet is. InSight launched toward Mars on May 5, 2018, landed on Nov. 26, 2018, at the Martian Elysium Planitia, an equatorial zone just south of an ancient volcanic area. InSight will send back data about Mars' interior for about 1 Mars year, or 728 Earth-days. The lander uses sophisticated instruments, to delve deep beneath the surface and seek the fingerprints of the processes that formed the terrestrial planets. It does so by carrying out → seismology, heat flow measurements, and precision tracking.

inspiral
  فروپیچه   
forupicé

Fr.: orbite plongeante en spirale   

The inward spiraling of an orbiting → black hole toward a central → supermassive black hole (SMBH) as it radiates → gravitational wave.

instability
  ناپایداری   
nâpâydâri (#)

Fr.: instabilité   

The condition of a system when it is disturbed by internal or external forces. The system continues to depart from the original condition, in contrast to a stable system, which will return to its previous condition when disturbed.

instability strip
  نوار ِ ناپایداری   
navâr-e nâpâydâri

Fr.: bande de l'instabilité   

A narrow, almost vertical, band on the right hand side of the → main sequence in the → H-R diagram occupied by many different types of → pulsating stars (→ RR Lyrae, → Cepheids, → W Virginis, → ZZ Ceti). Stars traverse this region at least once after they leave the main sequence. The narrow temperature range of the instability strip corresponds to the stellar → effective temperature that can sustain → partial ionization zones, capable of maintaining stellar oscillations. The blue (hot) edge of the instability strip pertains to stars with surface temperatures hotter than ~ 7500 K. Because these stars have partial ionization zones too close to their surface, the pulsation mechanism is not active. The red (cooler) edge of the instability strip is determined by stars with a temperature lower than ~ 5500 K. In these stars convection prevents the build-up of heat pressure necessary to drive pulsations.

instability; → strip.

install
  درهیدن   
darhidan

Fr.: installer   

1) To place in position or connect for service or use.
2) To establish in an office, position, or place (Dictionary.com).

Stall "stable," Stelle "place"), from PIE root *stel- "to put, stand;" cf. Gk. stele "standing block, slab," stellein "to set in order, arrange, array, equip, make ready."
