Apart from Aditya L1, here are some of the ongoing solar probe missions of the world:

* **Parker Solar Probe** (NASA): This is the first mission to "touch" the Sun. It is currently in orbit around the Sun, and it will eventually get as close as 4 million miles from the surface. Parker Solar Probe is studying the Sun's atmosphere and solar wind, and it is helping us to understand how the Sun works and how it affects our solar system.

* **Solar Orbiter** (ESA/NASA): This mission is studying the Sun from a different perspective than Parker Solar Probe. Solar Orbiter is orbiting the Sun in an elliptical orbit that takes it closer to the Sun than Mercury, but also further away than Venus. Solar Orbiter is studying the Sun's poles and the way the Sun's magnetic field interacts with the solar wind.

* **STEREO** (NASA): This mission consists of two spacecraft, STEREO-A and STEREO-B, that are orbiting the Sun in tandem. STEREO is studying the Sun's heliosphere, which is the region of space that is filled with solar wind. STEREO is also studying solar flares and coronal mass ejections, which are large eruptions of solar material that can affect Earth's atmosphere and climate.

* **SOHO** (ESA/NASA): This mission has been studying the Sun for over 20 years. SOHO is in a halo orbit around the Sun-Earth Lagrange point L1, which is a point in space where the gravitational pull of the Sun and Earth balance each other out. SOHO is studying the Sun's atmosphere, solar wind, and solar flares.

* **Yohkoh** (JAXA): This mission was launched in 1991 and studied the Sun's corona for over 10 years. Yohkoh was the first spacecraft to image the Sun's corona in X-rays.

These are just a few of the ongoing solar probe missions of the world. There are many other missions that are studying the Sun from different perspectives and using different instruments. These missions are helping us to learn more about the Sun and how it affects our solar system.
