The SOHO Spacecraft

The SOHO spacecraft was launched on December 2, 1995 where then it was directed to go about 930,000 miles sunward from the Earth to the L1 or the Lagrangian point. This “Lagrangian” point is a place between the Sun and the Earth where the gravity pulls of both masses stabilize the spacecraft enough to achieve a state of gravitational equilibrium between the two masses. At this point, the spacecraft then established its own “halo-like” orbit in space but continued to also orbit about the Sun in the same orbital path as the Earth. Once SOHO’s “halo-like” orbit was established, the spacecraft was then ready to open its payload bay doors and begin its probin

In conclusion, the SOHO space project has given scientists around the world a better understanding of the brightest star in our sky. It has helped scientists unravel old mysteries and gave rise to new ones. Finally, this project will deepen our knowledge of the relationship between ourselves here on Earth and the most important giver of life in the solar system, our Sun.

The sensitive instruments aboard the SOHO spacecraft have already helped scientists here on Earth discover and explain some of the mysteries of the Sun as well as to confirm some of their theories they previously held. For example, in May of 1998 with the help of the Michelson Doppler Interferometer scientists were able to see with greater clarity the giant convective cells inside and on the surface of the Sun. With this information, scientists are now able to make out patterns of these convective cells on the Sun which in turn enhance their ability to predict future space weather as it affects the Earth.
