Bonus #science opportunity for #SolarOrbiter, which will cross through the tails of #Comet ATLAS in the next few days. The mission's 4 in-situ instruments will be switched on and collecting data during the encounter

The commissioning of #SolarOrbiter has been proceeding over the past three months to ensure the spacecraft and instruments will be fully functional for the 1st close pass of the #Sun, to take place on 15 June, around 77 million km from our parent star.pic.twitter.com/EpnYxOhE9U
Meanwhile, @einionyn noticed that #SolarOrbiter would pass through the ion tail of Comet ATLAS on 31 May-1 June + through the dust tail on 6 June. Fortuitously, the 4 in-situ instruments that measure the conditions around the spacecraft are also great for studying #comet tails!pic.twitter.com/qKrmfDWFaq
Unexpected encounters like this provide unique opportunities & challenges. Thanks to a special effort by #SolarOrbiter instrument teams & @esaoperations, the 4 in-situ instruments will be on, even though at certain times they will need to be switched back into commissioning mode.pic.twitter.com/bZEeaoFayN
Another challenge is posed by the comet itself! In early April, Comet ATLAS fragmented & its brightness dropped significantly. A further fragmentation occurred mid-May, making it even less likely to be detectable by #SolarOrbiter – but the effort is still worth making #forsciencepic.twitter.com/kOhjIK2c6o
If #SolarOrbiter detects Comet ATLAS's presence, scientists could learn more about how #comets interact with the solar wind – the flow of charged particles released by the #Sun – and also about the dust environment of our star, as the comet nucleus is inside the orbit of Mercury.pic.twitter.com/khSl9tBhBZ
Looking at an icy object rather than the scorching #Sun is an exciting – and unexpected! – way for #SolarOrbiter to start its scientific mission, but that’s the nature of #science 
Stay tuned as the spacecraft approaches its first perihelion in mid June #WeAreAllSolarOrbiterspic.twitter.com/6C66AdaNbk
