@mike_colechin Umm… not sure I do. You’re referring to the chimney-like object? Espresso maker? Have I drunk coffee from it?!

@markp8183 do you remember this? Still going strong after all these years.

@HeckmannLea @uniinnsbruck @MAGICtelescopes Time goes fast… congratulations from Stockholm!

#PhDone I'm so grateful for everyone who shaped my path towards this, my supervisors, my amazing colleagues in Munich & @uniinnsbruck, and my wonderful collaboration @MAGICtelescopes. Thank you for everything and also for creating the most incredible hat I can imagine 🤩🥰

@esa @esascience @ESA_Tech Congratulations @CGMundell !

ESA appointed two new Directors - Director of @esascience and Director of @ESA_Tech. Carole G. Mundell (UK) was appointed as Director of Science and Dietmar Pilz (DE) as Director of Technology, Engineering and Quality, taking up duty in 2023 👉 esa.int/About_Us/Corpo…

A little late, but post-ceremony and post-dinner. A celebration of science!

@SandraDiRoccoSt @andersatlife @KTHuniversity Ja - tack för besöket! Det var kul att kunna visa upp Skolan.

@andersatlife @KTHuniversity Stort tack för ditt besök Anders!

Besök på SCI-skolan. Förutom möten med institutionerna, besök i lab och lektionssalar och samtal med forskare, lärare och doktorander, insyn i modern kärnenergiteknik, kolfiberkonstruktioner och matte för AI fick vi även avnjuta julsånger från verksamhetsstödet. @KTHuniversity

Nytt nummer av @PopAst just dropped! Skriver om min resa till Kiruna och Esrange där ballongteleskop studerar himlens ljusaste stjärna (gissa vilken det är!) och mörkaste svarta hål. Ping @SSCspace @SuperTigerLDB @Sunrise_III @markp8183

@RymdstyrelsenSE fyller 50! Kul att kunna fira med er!

Looks like we’ll soon get our hands on hardware again.

The XL-Calibur telescope and parachute landed near Délı̨nę, N.W.T., about 20 kilometres away from where the balloon ended up. cbc.ca/1.6527713

Phew.

More than happy to second that! @SSCSpaceSverige

And here’s the flight-path.

@SuperTigerLDB @FKislat @WUSTL @WUSTLArtSci @WashUPhysics @KTHuniversity @NASA_Wallops @UNHEOS @HiroshimaUnivEn @osaka_univ_e @NASAGoddard After 6 days, 7 hours, and 45 minutes, XL-Calibur has returned to Earth. More-or-less upright too, it appears.

Shout out to the XL-Calibur collaboration @WUSTL @WUSTLArtSci @WashUPhysics #stlmade @KTHuniversity @NASA_Wallops @UNHEOS @HiroshimaUnivEn @osaka_univ_e @NASAGoddard

@jegudmunds @SuperTigerLDB UFO!

@SuperTigerLDB and @markp8183 I think this might be your payload as seen from Iceland :)

After a particularly beautiful launch from the Esrange, the XL-Calibur balloon (@SuperTigerLDB, @WUSTL, @NASA_Wallops, @kthuniversity) is now on its 4-day trip to Canada. Along the way, the onboard telescope will examine black holes and neutron stars 💫🔭 sscspace.com/blog/2022/07/1…

XL-Calibur’s progress. We should reach Victoria Island (far left of map) in approx 5-7 days time.

I natt klockan 1:45 lyckades KTH:s forskarteam få upp ballongen med det enorma röntgenteleskopet XL-Calibur, som ska mäta svarta hål, på Esrange i Kiruna. Läs en intervju med professor Mark Pearce, @markp8183, om rymduppdraget: kth.se/om/nyheter/cen…

… and the moment of payload release at 01:45 this morning.

The moment of balloon release…
