PARIS (ESA PR) — ESA and the European Defence Agency (EDA) are embarking on new cooperative projects for exploring unknown or potentially hazardous environments: harnessing drones for the monitoring of disaster-stricken regions or toxic spill sites and making use of Artificial Intelligence (AI) to navigate across the surface of asteroids or other terra incognita.
Three years after the last ESA Council Meeting at Ministerial Level, held in Lucerne, Switzerland, government representatives from the 22 Member States met in Seville, Spain, on 27 and 28 November 2019 and committed a total of almost 14.4 billion euro [$15.87 billion] for space programmes over the next few years.
Germany is contributing 3.3 billion euro [$3.6 billion] to ESA programmes focusing on Earth observation, telecommunications, technological advancement and commercialisation / NewSpace.
At 22.9 percent, Germany is now ESA’s largest contributor, followed by France (18.5 percent, 2.66 billion euro), Italy (15.9 percent, 2.28 billion euro) and the United Kingdom (11.5 percent, 1.65 billion euro).
The ESA Council Meeting at Ministerial Level is the highest political decision-making body, and it defines the content and financial framework for ESA’s space programmes every two to three years.
Hera will be humanity’s first-ever spacecraft to visit a double asteroid, the Didymos binary system. First, NASA will crash its DART spacecraft into the smaller asteroid – known as Didymoon – before ESA’s Hera comes in to map the resulting impact crater and measure the asteroid’s mass.
Hera will carry two CubeSats on board, which will be able to fly much closer to the asteroid’s surface, carrying out crucial scientific studies, before touching down. Hera’s up-close observations will turn asteroid deflection into a well-understood planetary defence technique.
SEVILLE, Spain (ASI PR) — In Seville, Spain, the institutional representatives and heads of the countries that make up the European Space Agency (ESA) have set the course towards new spatial horizons in the coming years. The share of the Italian contribution rises, while Samantha Cristoforetti will return to orbit.
An increase of almost one billion euros [$1.1 billion] compared to the previous Ministerial is what the Italian delegation to the ESA Ministerial Council 2019 has destined as a contribution of our country to the budget of the ESA for the next three to four years.
NOORDWIJK, Netherlands (ESA PR) — Having spent much of the 21st century developing planetary defence techniques, Apollo astronaut Rusty Schweickart is a strong supporter of ESA’s proposed Hera mission. In general, when it comes to asteroid deflection, he says, two spacecraft are better than one.
ROME (ESA PR) — Asteroid researchers and spacecraft engineers from the US, Europe and around the world will gather in Rome next week to discuss the latest progress in their common goal: an ambitious double-spacecraft mission to deflect an asteroid in space, to prove the technique as a viable method of planetary defence.
This combined mission is known as the Asteroid Impact Deflection Assessment, or AIDA for short. Its purpose is to deflect the orbit of the smaller body of the double Didymos asteroids between Earth and Mars through an impact by one spacecraft. Then a second spacecraft will survey the crash site and gather the maximum possible data on the effect of this collision.
PARIS (ESA PR) — On 25 July, an asteroid the size of a football field flew by Earth, coming within 65 000 km of our planet’s surface during its closest approach – about one fifth of the distance to the Moon.
The 100 m-wide asteroid dubbed ‘2019 OK’ was detected just days before
it passed Earth, although archival records from sky surveys show it had
previously been observed but wasn’t recognised as a near-Earth asteroid.
While 2019 OK illustrates the need for even more eyes on the sky, it also provides an opportunity to improve the asteroid recognising abilities of current and future telescopes, including ESA’s upcoming ‘Flyeye‘.
TOULOUSE, France (ESA PR) — ESA’s Hera mission for planetary defence, being designed to survey the smallest asteroid ever explored, is really three spacecraft in one. The main mothership will carry two briefcase-sized CubeSats, which will touch down on the target body. A French team has been investigating what might happen at that initial instant of alien contact.
“We’ve customised an existing drop tower and rigged it up with a system of pulleys and counterweights in order to simulate a low gravity environment,” explains researcher Naomi Murdoch of the Institut Supérieur de l’Aéronautique et de l’Espace (ISAE-Supaero), part of the University of Toulouse.
Every single day, many tons of tiny rocks – smaller than pebbles – hit the Earth’s atmosphere and disintegrate. Between frequent shooting stars we wish on in the night sky and the massive extinction-level asteroids that we hope we never see, there is a middle ground of rocks sized to make it through the atmosphere and do serious damage to a limited area. Now, new research from NASA indicates that the impacts of these mid-size rocks may be less frequent than previously thought.
MOFFETT FIELD, Calif. (NASA PR) — The research revealed that such relatively small but regionally devastating impacts happen on the order of millennia – not centuries, as previously thought. In addition, the new research has pushed forward our knowledge about the complex processes that determine how large rocks from space break up when entering Earth’s atmosphere.

The Double Asteroid Redirection Test (DART) – NASA’s first mission to demonstrate a planetary defense technique – will get one chance to hit its target, the small moonlet in the binary asteroid system Didymos. The asteroid poses no threat to Earth and is an ideal test target: measuring the change in how the smaller asteroid orbits about the larger asteroid in a binary system is much easier than observing the change in a single asteroid’s orbit around the Sun. Work is ramping up at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, and other locations across the country, as the mission heads toward its summer 2021 launch – and attempts to pull off a feat so far seen only in science fiction films.
PARIS, 1 May 2019 (ESA PR) — Small enough to be an aircraft carry-on, the Juventas spacecraft nevertheless has big mission goals. Once in orbit around its target body, Juventas will unfurl an antenna larger than itself, to perform the very first subsurface radar survey of an asteroid.
ESA’s proposed Hera mission for planetary defence will explore the twin Didymos asteroids, but it will not go there alone: it will also serve as mothership for Europe’s first two ‘CubeSats’ to travel into deep space.
PARIS (ESA PR) — From Earth asteroids appear as little more than dots in the sky. Europe’s miniature APEX spacecraft will operate as a mineral prospector in deep space, surveying the make-up of its target asteroids down to individual boulders, helping prepare the way for future mining missions.
PASADENA, Calif. (NASA/JPL-Caltech PR) — On April 13, 2029, a speck of light will streak across the sky, getting brighter and faster. At one point it will travel more than the width of the full Moon within a minute and it will get as bright as the stars in the Little Dipper. But it won’t be a satellite or an airplane – it will be a 1,100-foot-wide (340-meter-wide) near-Earth asteroid called 99942 Apophis that will cruise harmlessly by Earth, about 19,000 miles (31,000 kilometers) above the surface. That’s within the distance that some of our spacecraft that orbit Earth.
The international asteroid research community couldn’t be more excited.
WASHINGTON (ESA PR) — For the first time, ESA will cover a major international asteroid impact exercise live via social media, highlighting the the actions that might be taken by scientists, space agencies and civil protection organisations.
Every two years, asteroid experts from across the globe come together to simulate a fictional but plausible imminent asteroid impact on Earth. During the week-long scenario, participants – playing roles such as ‘national government’, ‘space agency’, ‘astronomer’ and ‘civil protection office’ – don’t know how the situation will evolve from one day to the next, and must make plans based on the daily updates they are given.
For the first time, ESA will cover progress of the hypothetical impact scenario from 29 April to 3 May live via social media, primarily via the @esaoperations Twitter channel. (more…)
PARIS (ESA PR) — Incoming asteroids have been scarring our home planet for billions of years. This month humankind left our own mark on an asteroid for the first time: Japan’s Hayabusa2 spacecraft dropped a copper projectile at very high speed in an attempt to form a crater on asteroid Ryugu. A much bigger asteroid impact is planned for the coming decade, involving an international double-spacecraft mission.
