A key element of ESA’s role as Europe’s space agency is the expansion of space knowhow, by encouraging new actors into the field. Case in point: a Polish software company previously specialising in smartphone apps took on the challenge of designing the operating system for the main instrument of Proba-3 – an ambitious double spacecraft mission to reveal secrets of the Sun’s fiery atmosphere, the corona.

For the first time, the NASA/ESA/CSA James Webb Space Telescope has detected and ‘weighed’ a galaxy, in the early Universe, that has a mass that is similar to what our Milky Way galaxy’s mass might have been at the same stage of development. Found at around 600 million years after the Big Bang, this lightweight galaxy, nicknamed the Firefly Sparkle, is gleaming with star clusters – 10 in total – that researchers examined in great detail. Other galaxies Webb has detected at this period in the history of the Universe are significantly more massive. View the full article

Video: 00:03:40 The third Copernicus Sentinel-1 satellite, Sentinel-1C, has launched aboard a Vega-C rocket, flight VV25, from Europe’s Spaceport in French Guiana. The rocket lifted off on 5 December 2024 at 22:20 CET (18:20 local time). Sentinel-1C extends the legacy of its predecessors, delivering high-resolution radar imagery to monitor Earth’s changing environment, supporting a diverse range of applications and advance scientific research. Additionally, Sentinel-1C introduces new capabilities for detecting and monitoring maritime traffic. The launch also marks Vega-C’s ‘return to flight’, a key step in restoring Europe’s independent access to space. Vega-C is the evolution of the Vega family of rockets and delivers increased performance, greater payload volume and improved competitiveness. View the full article

Today, ESA’s powerful X-ray observatory, XMM-Newton, celebrates 25 years in space. From planets to black holes, the space telescope has delivered many ground-breaking observations of a variety of celestial objects. And the mission is still going strong as recent results testify. We take a look at five fascinating discoveries from the last five years. View the full article

Video: 00:01:21 Proba-3 lifted off on its PSLV-XL rocket from Satish Dhawan Space Centre in Sriharikota, India, on Thursday, 5 December, at 11:34 CET (10:34 GMT, 16:04 local time). The mission was launched using this Indian launcher because it needed to be placed in a highly elliptical orbit extending more than 60 500 km from the ground. After integration and testing was completed at Redwire Space in Belgium, Proba-3 was transported to India to be prepared for launch. The latest member of ESA’s family of in-orbit demonstration missions, Proba-3 is in fact two spacecraft being launched together, which will separate in orbit to begin performing precise formation flying, precise to a single millimetre, about the thickness of an average fingernail. To prove their performance, Proba-3 has been devoted to an ambitious scientific goal. The pair will line up precisely with the Sun 150 m apart so that one casts a precisely controlled shadow onto the other. By blocking out the fiery disc of the Sun, Proba-3’s ‘Occulter’ spacecraft will mimic a terrestrial total solar eclipse, to open up views of the Sun’s faint surrounding atmosphere, or ‘corona’, which is a million times fainter than its parent star. Proba-3’s second ‘Coronagraph’ spacecraft hosts the optical instrument that will observe the solar corona. If Proba-3’s initial commissioning phase goes to plan then the spacecraft pair will be separated early in the new year to begin their individual check-outs. The operational phase of the mission, including the first observations of the corona through active formation flying, should begin in about four months. Proba-3 was led for ESA by Sener in Spain, overseeing a consortium of 14 ESA Member States and Canada including Airbus Defence and Space in Spain manufacturing the spacecraft and Redwire Space in Belgium responsible for the spacecraft avionics, assembly and operations. CSL in Belgium produced Proba-3’s ASPIICS coronagraph Spacebel in Belgium developed the onboard and ground segment software with GMV responsible for the formation flying system and flight dynamics.

A pair of spacecraft were launched together today from India with the potential to change the nature of future space missions. ESA’s twin Proba-3 platforms will perform precise formation flying down to a single millimetre, as if they were one single giant spacecraft. To demonstrate their degree of control, the pair will produce artificial solar eclipses in orbit, giving prolonged views of the Sun’s ghostly surrounding atmosphere, the corona.

Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have found new galaxies in the Spiderweb protocluster.

Video: 00:09:01 Proba-3 is such an ambitious mission that it needs more than one single spacecraft to succeed. In order for Proba-3’s Coronagraph spacecraft to observe the Sun’s faint surrounding atmosphere, its disk-bearing Occulter spacecraft must block out the fiery solar disk. This means Proba-3’s Occulter ends up facing the Sun continuously, making it a valuable platform for science in its own right. Proba-3 is scheduled for launch on a PSLV-XL rocket from Satish Dhawan Space Centre in Sriharikota, India, on Wednesday, 4 December, at 11:38 CET (10:38 GMT, 16:08 local time). View the full article

ESA’s Proba-3 will be the first mission to create an artificial total solar eclipse by flying a pair of satellites 150 metres apart. For six hours at a time, it will be able to see the Sun’s faint atmosphere, the corona, in the hard-to-observe region between the Sun’s edge and 1.4 million kilometres from its surface. This new technology combined with the satellite pair’s unique extended orbit around Earth will allow Proba-3 to do important science, revealing secrets of the Sun, space weather and Earth’s radiation belts.

Video: 00:02:39 The Ignis mission, named after the Latin word for ‘fire,’ symbolises the spark igniting a new era in Poland’s space endeavours. The central motif of the patch features an eagle – a reference to the emblem of Poland – in white and red, reflecting the colours and design of the Polish national flag. Its tail gracefully evokes a flame, while its outstretched wings trace the contours of the Orla Perć mountain range in the Polish Tatra Mountains. Within the mission’s name, the second ‘i’ takes the form of the International Space Station. Above it, stars converge to form the Scutum constellation, paying homage to astronomer Johannes Hevelius (1611-87), who was born in the Polish city of Gdańsk. Finally, a silver line represents the horizon, signifying the dawn of a new era in space exploration. For more details, read the press release here. Follow Sławosz’s journey on the Ignis website.
