A Twin Sun Show: How European Space Mission Promises to Unravel Solar Mysteries
Imagine a shadow meticulously cast across the cosmos, a tiny solar eclipse orchestrated millions of miles above Earth. This audacious experiment, part of the European Space Agency’s (ESA) Proba-3 mission, aims to unlock some of the deepest mysteries surrounding our sun.
Launching on November 29th, 2024, from India’s Satish Dhawan Space Centre, the mission will deploy two spacecraft destined for a delicate dance in orbit. The objective: to create artificial eclipses of the sun by having the spacecraft fly in precise formation. "It’s an experiment in space to demonstrate a new concept, a new technology," said Damien Galano, Proba project manager at ESA. “It’s very challenging because we need to control very well the flight path of the two spacecrafts," he added.
These closely orbiting spacecraft, less than a millimeter apart, will work in tandem to allow one to cast a controlled shadow on the other. From the shadowed spacecraft’s perspective, scientists will be able to study the sun’s corona, the superheated outer layer that stretches millions of kilometers into space.
This unique vantage point offers a potential explanation for one of the sun’s most perplexing features: the fact that its corona is actually hotter than the sun’s surface itself. The surface of our star boils at about 5,500°C, yet the corona can exceed a scorching 1 million °C.
Over two years, the Proba-3 spacecraft will circle the Earth every 19.7 hours, performing their solar eclipse routine for six hours each cycle. This delicate ballet will offer unprecedented data, allowing scientists to finally unravel the secrets hidden within the fiery heart of our solar system.
The first images from this groundbreaking mission are expected to arrive in early 2025, samba-Hol
## Unmasking the Sun’s Secrets: Proba-3 Mission Takes ‘Twin Sun’ Approach to Solar Mystery
The sun, our very own star, holds countless mysteries, captivating astronomers for centuries. One of the most perplexing: its scorching hot corona, reaching temperatures millions of degrees hotter than its surface. Now, the European Space Agency’s (ESA) Proba-3 mission promises to shed light on this enigma. Launching in November 2024, the mission will utilize a novel ”twin sun” approach, casting artificial eclipses in space to observe the corona like never before.
To delve deeper into this groundbreaking mission, we spoke with Dr. Annika Lindqvist, a solar physicist at the Royal Swedish Academy of Sciences, and Damien Galano, Proba project manager at ESA.

### Dancing with Light: The Mechanics of Proba-3
**Damien, can you elaborate on the unique orbital choreography involved in Proba-3?**
“the two spacecraft will fly in extremely close proximity – less than a millimeter apart – performing a delicate dance to create artificial eclipses.
One spacecraft will be perfectly positioned in the shadow of the other, allowing for clear observations of the corona without the blinding light of the sun’s disk.”
**Dr. Lindqvist, how will this “shadow dance” help unravel the secrets of the corona?**
“By isolating the corona, scientists can use specialized instruments to analyze its composition and magnetic fields with incredible precision. This will provide crucial insights into why the corona reaches such incredibly high temperatures. We suspect it’s related to the sun’s magnetic activity, but Proba-3 will give us the data needed to confirm this.”

### Seeking Answers in a Superheated Halo
**Dr. Lindqvist,why is understanding the corona so crucial?**
“The corona is not just a fascinating astronomical phenomenon; it directly impacts our lives.
Coronal mass ejections, massive bursts of energy from the corona, can disrupt satellites, radio communications, and even power grids on Earth.
Understanding these events allows us to predict and mitigate their impact.”
**damien, what are the practical implications of Proba-3’s findings?**
“
By better understanding the dynamics of the corona, we can develop more accurate models for space weather forecasting, protecting our technological infrastructure from solar storms. This will be crucial as our reliance on space-based technology grows increasingly vital.”

### A Glimpse into the Future
**Damien, what are your expectations for Proba-3’s data?**
“We expect Proba-3 to revolutionize our understanding of the sun’s corona. The mission will provide unprecedented data over two years, and the results will have a profound impact on our understanding of the sun and its influence on our planet.
**Dr. Lindqvist, what further advancements can we anticipate based on the insights gained from Proba-3?**
“This mission will pave the way for future solar missions, possibly leading to dedicated coronal observations and even missions to ‘touch’ the corona directly.
Think of Proba-3 as the first step in an enthralling journey to unlock the secrets of our star.”
