CubeSat Radio Interferometry Experiment (CURIE)

About CubeSat Radio Interferometry Experiment (CURIE): 

• It aims to investigate the enigmatic origins of radio waves emanating from the Sun, a phenomenon first observed decades ago.
• The mission employs an innovative technique called low frequency radio interferometry, marking its first use in space.
  • CURIE consists of two miniature spacecraft, collectively no larger than a shoebox, which will orbit Earth approximately two miles apart.
  • This separation enables the instruments to detect minute differences in radio wave arrival times, pinpointing their exact solar origin.
• Working
  • This spacecraft will measure radio waves in the 0.1 to 19 megahertz range, frequencies blocked by Earth's upper atmosphere, necessitating space-based observations.
  • CURIE will orbit 360 miles above Earth's surface to obtain an unobstructed view of the Sun's radio emissions.
  • Once in orbit, the two CURIE spacecraft will separate, deploy their eight-foot antennas, and begin collecting data.
  • This mission not only promises to advance our understanding of solar phenomena but also paves the way for future space-based radio astronomy endeavors
• It is sponsored by NASA’s Heliophysics Flight Opportunities for Research and Technology (H-FORT) Program.

Q1. What are the features of Radio waves?

They have the longest wavelengths in the electromagnetic spectrum, ranging from about 1 millimetre to 100 kilometres. Their frequencies are the lowest among electromagnetic waves, spanning from about 3 kHz to 300 GHz.
