Dodging debris to keep satellites safe






Video: 00:01:31

Our planet is surrounded by spacecraft helping us study our changing climate, save lives following disasters, deliver global communication and navigation services and help us answer important scientific questions.

But these satellites are at risk. Accidental collisions between objects in space can produce huge clouds of fast-moving debris that can spread and damage additional satellites with cascading effect.

In this animation, find out how teams at ESA’s European Space Operations Centre in Darmstadt, Germany, take action to keep satellites safe after receiving an alert warning of a possible collision between an active satellite and a piece of space debris.

When the alert is raised, ESA experts determine the risk of a collision and plan a collision avoidance manoeuvre that can be used to get the satellite out of harm’s way if necessary.

Additional observations of the piece of space debris help the team better understand its path and the risk of collision. If that risk remains too high (typically 1 in 10 000), the planned manoeuvre is carried out to temporarily change the orbit of the satellite until the threat has passed.

Each manoeuvre comes at a price. They take skill and time to plan, cost precious fuel – shortening the lifetime of the mission – and often require instruments to be temporarily shut off, preventing them from collecting important data.

While most alerts do not end up requiring evasive action, the number of alerts is rapidly increasing. Hundreds are already issued every week. Several companies have begun to launch large constellations into low-Earth orbit to provide global internet access. They have great benefits, but could be a source of huge disruption if we do not change our behaviour.

In just a few years, our current methods for avoiding collisions in space will no longer be enough. To safeguard humankind’s continued access to space for future generations, ESA is developing technologies for an automated collision avoidance system.

Find out more about ESA’s Space Debris and Clean Space Offices, both part of the Space Safety Programme, and the Agency’s conference on space debris - the world’s largest on the topic - taking place in April 2021.

Measuring shoreline retreat








Climate change is having an undeniable influence on coastal areas. A substantial proportion of the world’s sandy coastlines are already eroding owing to increased storm surges, flooding and sea level rise. With our coastal environments in constant change, Earth observation satellites are being used to better strengthen our knowledge of changing coastlines.

Thomas Pesquet: Biography and training






Video: 00:03:00

Born in Rouen, France, aerospace engineer and commercial pilot Thomas Pesquet was selected for ESA’s Astronaut Corps in 2009. He was launched on his first flight to the International Space Station in November 2016, remaining in space until June 2017 as part of his Proxima mission. He will soon be launched for on his second long-duration mission to the International Space Station called Alpha. Thomas has been training with the Station’s international partners for the new mission, including learning about the Crew Dragon, he will be the first ESA astronaut to fly on this new commercial spacecraft.

This A&B Roll highlights Thomas Pesquet’s early training with the European Astronaut Corps, his first spaceflight, and preparations for the upcoming Alpha mission, with soundbites in English and French.

Meteorite Older Than the Sun Found in a U.K. Driveway

There are two ways to get your hands on a meteorite. You can send up a billion-dollar robot to retrieve asteroid samples, or you can wait for a friendly space rock land at your doorstep for free. The latter option happened on February 28th, when a rare meteorite from the early solar system landed in a driveway in Winchcombe, England.

Scientists call this kind of meteorite “carbonaceous chondrite.” It contains a lot of carbon, so it looks a lot like coal, but carbonaceous chondrite actually dates back to the beginnings of our solar system and could help us understand Earth and other planets came to be. If this is like other samples of carbonaceous chondrite, it should also contain bits of diamond, graphite, and soft clay—a sign that the rock encountered water at some point.

Residents of Winchcombe, England, noticed a fireball reigning down before exploding in the sky the night of Sunday, February 28th. The next day, someone found the rock in their driveway, bagged it up, and contacted the U.K. Meteor Observation Network.

As noted by the Natural History Museum, the Winchcombe Meteorite is significantly larger than rocks collected by billion-dollar space probes. The Hayabusa2 probe returned to Earth last year with just 4.5 grams of asteroid rock, while the OSIRIS-REx probe is expected to return in 2023 with 60 grams of rock. But the Winchcombe Meteorite is 300 grams. Good things come to those who wait, I guess.

Italian ESA astronaut Samantha Cristoforetti poses in the Cupola module of the International Space Station with two 100-day patches to mark her 200th day in space. In 2022, she will return to her ‘home away from home’ for even more days in orbit.

Samantha first flew to the International Space Station on a Soyuz spacecraft in 2014 for a mission known as ‘Futura’. Her second flight follows the second missions of her fellow 2009 astronaut classmates Alexander Gerst in 2018, Luca Parmitano in 2019 and Thomas Pesquet in 2021. It could also see a direct on-Station handover with Matthias Maurer who is scheduled to fly his first mission to the Space Station later this year. The spacecraft Samantha will fly on is not yet confirmed, but could be a SpaceX Crew Dragon or Boeing CST-100 Starliner.

During Futura, Samantha supported an extensive scientific programme of experiments in physical science, biology and human physiology as well as radiation research and technology demonstrations.

She also oversaw the undocking of ESA’s fifth and final Automated Transfer Vehicle (ATV). This marked the end of a successful programme that paved the way for the European Service Modules currently being produced for NASA’s Orion spacecraft that will travel around and to the Moon.

Training for Samantha’s second mission is already underway and has included International Space Station refresher sessions at ESA’s astronaut centre in Cologne, Germany, and NASA’s Johnson Space Center in Houston, Texas.

In the coming months, her schedule will intensify as she brushes up on Space Station systems and procedures and trains for the specific experiments and tasks she will perform in space.

More details of Samantha’s second mission will be announced during a virtual press briefing on Wednesday, 3 March, at 11:00 CET. Watch on ESA Web TV here.

ESA is also in the process of recruiting its next class of astronauts. For more on the upcoming selection visit esa.int/YourWayToSpace.
