Infographic showing the match between animals and ESA's rockets.

To space! But on which rocket?
Teams at Mission Control match the needs of ESA missions with the perfect rocket. The choice of rocket depends primarily on the mass of the payload and where it needs to go.

The further from Earth a spacecraft needs to be lifted, and the more massive it is, the more fuel that is needed.

To the Moon and beyond

The minimum velocity required to get beyond Earth’s gravitational sphere of influence is 11.2 km per second, after which point spacecraft engines and planetary flybys are used to reach deep space destinations.

The mighty Ariane 64 can accelerate 6900 kg (or a large orca) to this important speed.

To geostationary transfer orbit

Most communication and weather satellites live about 36 000 km above Earth’s equator in geostationary orbit - from where they appear to hover unmoving above our heads.

The Ariane 62 can lift 5000 kg (or an Asian elephant) to the geostationary transfer orbit, and the Ariane 64, 11 500 kg (or a whale shark), from where spacecraft boost themselves into geostationary orbit.

Orbiting near Earth

Most human-made objects in space reside in low-Earth orbit, from 100 km to 2000 km above Earth’s surface.

The nimble Vega-C can carry 2250 kg (or a hippopotamus) to this crowded zone, while the Ariane 62 can lift up to 10 300 kg (or an African elephant) and the mighty Ariane 64 a whopping 21 600 kg (or a small grey whale).

Today is International Biodiversity day!

What does that have to do with rockets?

Some of the satellites we send to space are used to track biodiversity... and our designers like to do cool infographics that compare payloads to animal weight!

You’re whale-come! 🐋

I suggest you give a try to the audiobooks, in this case they don’t replace printed versions but enrich them…

I hope we’ll call it the “Ariane Grande”

When you used the song “Mala Vida” , any particular reason you used that version instead of the original by Mano Negra? music.apple.com/nl/album/mal...

I loved them! I think I’m having the most fun with G. I. Robot. The Frankenstein montage scene was awesome too.

While we wait for the next Vega-C launch #VV25 , this a backstage video I shot back in 2021 for the #VV20 Vega launch of Ceres. This is one of the setups to show almost live video of a launch. #ESA @cnes.bsky.social #CSG #Videlio @eurospacehistory.bsky.social

I captured this moment with the iconic Soyuz launch site at the Guiana Space Centre back in November 2021. Just three months later, Russia invaded Ukraine, and this site launched Soyuz no more—a snapshot just before everything changed. 🚀 en.m.wikipedia.org/wiki/Soyuz_a... #SpaceHistory #Space

A successful encounter! #ESA #BepiColombo passed Mercury today, gathering valuable science data. 🛰️🌖
Here's an image taken at 10:46 UTC (11:46 CET) 1 December, from ~51000km from the surface.

Congratulations to our amazing teams for this next milestone towards Mercury orbit.

Group photo from the 2024 IAF IAC IPMC YP Workshop Final Event which was held in Milan, Italy, in October 2024. The group is of ~50 people in business smart clothes and most are wearing lanyards of the events.

While grounded at Paris CDG airport due to the snow (!), I thought I’d take a minute to encourage any early career professionals in the space industry to apply to something very special: the IAC IPMC Young Professionals Workshop on Project Management. That sounds pretty dry, but let me explain 🔭🧵⬇️

It was an MSX, I don’t recall the exact model as I was only 6 y.o. We had them in school and in that class we learnt to program Logo and Basic.

Twas the day before Christmas… Throwback to December 24, 2021 – just me, an Ariane 5 rocket, a day before the James Webb Space Telescope launch 🚀✨ Standing next to history in the making at the Guiana Space Centre. Any guesses what I was thinking at this moment? #Ariane5 #JamesWebb #SpaceChristmas

Yup, experience seems better so far. More space stuff and less crazy politics in my feed.

Linn was one of the best YGTs that ever worked for ESA. Huge opportunity to hire her while dhe’s available! (YGT: Young Graduate Trainee - ESA: European Space Agency)

depends on how fancy the domain is, around 30 bucks normally.
