Some history behind small deep-space missions, behind the scenes 20 years ago with Prof. Fujimoto @ISAS_JAXA 👉 cosmos.isas.jaxa.jp/a-rebel-allian… #HeraMission

Asteroids and solar storms and space debris, oh my! Explore the upcoming fleet of ESA Space Safety missions dedicated to safeguarding humans and infrastructure on Earth and in orbit from hazards originating in space: esa.int/ESA_Multimedia…

ESA‘a first stand-alone deep space CubeSat mission - Henon has successfully completed its Critical Design Review. Read more:👇 esa.int/Enabling_Suppo…

Pushing the boundaries of small spacecraft autonomy 🛰️ NASA’s Starling 1.5+ mission tested software that enabled its four spacecraft to make decisions, coordinate, and operate independently in low Earth orbit. Advancing this technology paves the way for autonomous spacecraft swarms to support missions to the Moon, Mars, and beyond—where real-time communication is limited. Learn more: go.nasa.gov/3VtwK79

🚀Pushing boundaries in deep space power systems? We are. Be there as we unveil the future of CubeSat exploration with our latest paper: "Enabling Deep Space High-Power CubeSat Exploration", presented at Small Satellite Conference (SmallSat) 2025. Discover how CURIE PCDU enables electric propulsion and high-power payloads for deep space missions. 🗓 Wednesday, August 13 🕚 11:00 AM MDT 📍 Grand Ballroom, Small Satellite Conference – Salt Lake City, Utah 🎙 Emilio Fazzoletto, Head of Product Management Interested in learning more or connecting on-site?

Pushing the boundaries of innovation and exploration has always been at the heart of Argotec's mission. Today we celebrate a new milestone: as prime contractor for HENON, ESA's first stand-alone CubeSat deep space mission for space weather monitoring, we have officially started the final implementation phase of the mission. Another step forward for Argotec and our incredible team! Read the article: esa.int/Enabling_Suppo…

Excited to work closely with this special team to turn the design into a flight ready spacecraft - the first of its kind! GO HENON! esa.int/Enabling_Suppo…

Asteroid 2024 YR4 no longer poses a significant impact risk. ESA's latest analysis has reduced the probability of an Earth impact in 2032 to 0.001%. Planetary Defenders continue to keep watch for any other asteroids that may come too close for comfort🛡️🔭 esa.int/Space_Safety/P…

Autonomy will help us all on Earth and in the solar system and the Starling spacecraft swarm moved us forward in this area: “The accomplishments of DSA [Deep Space Autonomy] onboard Starling include the first fully distributed autonomous operation of multiple spacecraft, the first use of space-to-space communications to autonomously share status information between multiple spacecraft, the first demonstration of fully distributed reactive operations onboard multiple spacecraft, the first use of a general-purpose automated reasoning system onboard a spacecraft, and the first use of fully distributed automated planning onboard multiple spacecraft.”

The best place to test new space technologies? Space! 🚀 At the 17th #EuropeanSpaceConf @BBE_Europe, @esa's TEC Director signed a deal with a pool of small satellite companies that will take promising technologies to space for testing as part of @EU_Commission’s programme to boost space tech innovators 👉 esa.int/Enabling_Suppo… 📸ESA - P. Sebirot

On Day 1 of #EuropeanSpaceConf @BBE_Europe 🛰️ @esa's Ian Carnelli presented the first-of-its-kind eclipse-making Proba-3 mission. Here’s how the twin satellites will be creating artificial solar eclipses on demand 👉 esa.int/ESA_Multimedia… 📸ESA - P. Sebirot

Shuttle between orbits 🔴🚀 @esa’s LightShip initiative aims to make future trips to Mars more frequent and affordable. Consortia led by @Argotec_Space, @Deimos_Space_, @polimi & @SITAELspa, and @redwire are now exploring what LightShip’s passenger spacecraft could look like 👉esa.int/Enabling_Suppo…

Proba-3 twin satellites separated!🛰️🛰️Under the watchful eye of operations team at @esa's ESEC, the pair said goodbye to each other last night, 14 January 23:00 GMT. When their Sun-observing mission starts, the two will adopt a stable configuration at 150 m away from each other, ready to create artificial eclipses on demand☀️esa.int/Enabling_Suppo…

A fall of CubeSats... A quartet of @ESA shoebox-sized missions reentered Earth's atmosphere recently, concluding busy working lives doing everything from monitoring solar storms' effects on Earth's magnetic field to trading cryptocurrency from orbit👉esa.int/Enabling_Suppo…
