Today's X2.9 solar flare likely came from old sunspot region 3664 which was the source of many major X-class solar flares during its previous visit of the earth-facing solar disk and an extreme G5 geomagnetic storm which was the first of its kind in 21 years. The solar flare was highly eruptive but the resulting coronal mass ejection is not aimed towards our planet. What a return.
What keeps you up at night? For us, it’s thinking about new ways that our missions could go wrong – and how to solve them!
As @ESASolarOrbiter swoops past the Sun, we’ve been practicing how to recover the spacecraft if it were to lose sight of Earth.

Saddened to hear of the passing of Eugene Parker. He predicted the existence of the solar wind and advanced many areas of solar physics. An incredible contribution to human knowledge. https://t.co/SIJCa9Oi3B
It’s still early to say what the real contribution of campfires 🔥 is to the coronal heating, but these are great news! Just one out of 50+ papers submitted to @AandA_journal describing the @ESASolarOrbiter first results!
🎉 A fitting tribute to celebrate solar physicist Kees de Jager's 100th orbit around the #Sun: two very special #SolarOrbiter photos taken earlier today at 00:19:21 and 00:20:21 CEST to represent the years 1921 and 2021 🎂#HappyBirthday#WeAreAllSolarOrbiters

☀️Happy #SUNday! ☀️Who's ready for a #VenusFlyby?! We're making a close approach at 12:39 GMT today, the first of many to set us on course to give us the best views of the Sun's poles yet 🛰🟠⤴️

Exciting times! Processing the first instrument commanding for Solar Orbiter’s early science phase (aka Cruise phase), starting 15June.
Checking all commanding for consistency against overall science/calibration plan, before forwarding to ESOC and spacecraft. #ESAsolarorbiter
Such a beautiful launch of Solar Orbiter, impressive! It looked like it was heading to the moon but it will for sure go and study the Sun !#SolarOrbiter#ESA
Ook Anik De Groof kijkt vol spanning uit naar de lancering van
@SolarOrbiter
⏰ 🕰️ ⌛
Afspraak vanaf 4u30 MET (Belgische tijd) voor de lancering om 5u03, live te volgen op https://t.co/lw2OjeYGCn
Tot straks!

Who’s watching the #MercuryTransit on Monday? ☀️🌑🔭😎
New to transits? Here’s what we mean when we’re talking about transits in astronomy, & why we we're looking forward to this one in particular👇
Details about Monday’s event via @timeanddate: https://t.co/XJTuIpZhAF
Destination: Shuttle Landing Facility 🤩
After a scheduled stop, the next destination for #SolarOrbiter is @NASAKennedy.
We're following on @flightradar24:

A rough estimate of more than 1000 engineers, scientists and experts from universities, research centres and industry all over Europe and USA worked very hard for building our @ESASolarOrbiter spacecraft during the last 10 years #WeAreAllSolarOrbiters#SolarOrbiter#esa#nasa
