The first of a series of global maps aimed at quantifying change in carbon stored as biomass across the world’s forests and shrublands has been released today by ESA’s Climate Change Initiative at COP25 – the United Nation Climate Change Conference currently taking place in Madrid.

New reentry CubeSat in orbit

ESA’s latest space mission has reached orbit. The Qarman CubeSat flew to space aboard SpaceX’s Dragon launched from Florida, USA, on Thursday 5 December, ahead of a planned rendezvous with the International Space Station on Sunday 8 December. From there, Qarman – seen here during plasma wind tunnel testing – will be deployed into space in late January 2020.

CubeSats are low-cost nanosatellites based around standard 10 cm units and typically end their spaceflights burning up in the atmosphere as their orbits gradually decay. But the three-unit Qarman (QubeSat for Aerothermodynamic Research and Measurements on Ablation) is designed with this fiery fate in mind.

Designed for ESA by Belgium’s Von Karman Institute, Qarman will use internal temperature, pressure and brightness sensors to gather precious data on the extreme conditions of reentry as its leading edges are enveloped in scorching plasma.

Qarman’s blunt-nosed front contains most of its sensors, protected by a cork-based heatshield. The CubeSat is expected to survive its reentry, although not its subsequent fall to Earth – making it imperative that its results make it back in the time in between, using the Iridium commercial satellite network.

Other ESA cargo launched for the International Space Station includes radiation-resistant aquatic organisms to study their secrets and learn how they could protect astronauts and people on Earth from harmful radiation.

Life of a foam

A fine coffee froth does not last forever. The bubbles that make the milk light and creamy are eventually torn apart by the pull of gravity. But there is a place where foams have a more stable life – in the weightless environment of the International Space Station, bubbles don’t burst so quickly and foams remain wet for longer.

Mato Grosso, Brazil

The Copernicus Sentinel-1 mission takes us over part of the Brazilian state of Mato Grosso deep in the Amazon interior.

This image combines three separate radar images from the Copernicus Sentinel-1 mission taken about two years apart to show change in crops and land cover over time.

Unlike images from satellites carrying optical or ‘camera-like’ instruments, images acquired  with imaging radar are interpreted by studying the intensity of the backscatter radar signal, which is related to the roughness of the ground.

Here, the first image, from 2 May 2015, is picked out in blue; the second, from 16 March 2017, picks out changes in green; and the third from 18 March 2019 in red; areas in grey depict little or no change between 2015 and 2019.

Ironically, Mato Grosso means ‘great woods’, but, as these coloured rectangular shapes portray, much of the tropical forest has been cut down and given over to farming. While this image only shows a small area, Mato Grosso is one of Brazil’s top cattle-producing and crop-producing states, with the main crops including corn, soya and wheat.

However, although the state has one of the highest historical rates of deforestation in Amazonian Brazil, deforestation is slowing and Mato Grosso is now said to be a global leader in climate-change solutions.

As an advanced radar mission, Copernicus Sentinel-1 can image the surface of Earth through cloud and rain and regardless of whether it is day or night. This makes it ideal for monitoring areas that tend to be covered by cloud such as rainforests.

Video: 00:02:45

ESA’s first mission dedicated to investigating planets outside our solar system is scheduled for launch on a Soyuz rocket from the European spaceport in French Guiana on 17 December 2019.

Cheops – Characterising ExOPlanet Satellite – will study known exoplanets that are orbiting bright stars. The aim is to obtain detailed information about these planets to find out more about their composition and internal structure.

The mission is a partnership between ESA and Switzerland with additional contributions from Austria, Belgium, France, Germany, Hungary, Italy, Portugal, Spain, Sweden and the UK.

35-year data record charts sea-temperature change

5. Detsember 2019 - 18:47

Four trillion satellite measurements, taken over four decades from 1981 to 2018, have been merged to create a continuous global record that will help to understand the science behind Earth’s climate.

A paper published recently in Nature Scientific Data describes how this new dataset of global sea-surface temperature is one of the longest satellite climate data records available. The dataset will play a key role in evaluating global models used to predict how our oceans will influence future climate change.

Sentinel-6: charting sea level

In a cleanroom in Ottobrunn, Germany, the latest Copernicus Sentinel satellite is ready for final testing before it is packed up and shipped to the US for liftoff next year. Designed and built to chart changing sea level, it is the first of two identical Sentinel-6 satellites that will be launched consecutively to continue the time series of sea-level measurements. This new mission builds on heritage from previous ocean topography satellites, including the French–US Topex-Poseidon and Jason missions, previous ESA missions such as the ERS satellites, Envisat and CryoSat, as well as Copernicus Sentinel-3. With millions of people around the world at risk from rising seas, it is essential to continue measuring the changing height of the sea surface so that decision-makers are equipped to take appropriate mitigating action – as is being currently highlighted at the COP-25 Climate Change Conference in Spain.

Thermal enclosure for Orion

The Orion spacecraft with European Service Module at NASA’s Plum Brook Station. The first Orion will fly farther from Earth on the Artemis I mission than any human-rated vehicle has ever flown before – but first it will undergo testing to ensure the spacecraft withstands the extremes of spaceflight.

Here at NASA’s Plum Brook Station in Ohio, USA, Orion is being put into a thermal cage in preparation of getting its first feel of space in the world’s largest thermal vacuum chamber.

Orion will be subjected to temperatures at Plum Brook ranging from –115°C to 75°C in vacuum for over two months non-stop – the same temperatures it will experience in direct sunlight or in the shadow of Earth or the Moon while flying in space.

In the picture, Orion is being placed in a cage, called the Thermal Enclosure Structure (TES), that will radiate infrared heat during the tests inside the vacuum chamber.

The tests that will be run over the next few months will show that the spacecraft works as planned and adheres to the strictest safety regulations for human spaceflight. The European Service Module has 33 thrusters, 11 km of electrical wiring, four propellant and two pressurisation tanks that all work together to supply propulsion and everything needed to keep astronauts alive far from Earth – there is no room for error.

Centre swage

'Swage' was the word of the day on Monday as ESA astronaut Luca Parmitano carried out the third spacewalk to service the cosmic ray hunting Alpha Magnetic Spectrometer AMS-02. Here Luca is suspended above Earth as he is moved to a second worksite to swage, or join, the instrument’s tubes to a new pump system that will give it a new lease on life.

Riding on the International Space Station’s robotic arm, Luca soared to the cosmic ray detector’s worksite for nearly five hours of space plumbing.

Yesterday’s spacewalk was the most critical of four spacewalks planned to service the Alpha Magnetic Spectrometer that has provided scientists with invaluable data on cosmic particles long after its original three-year mission. In 2017 the decision was made to service the instrument after all four cooling systems wore out.

Luca and NASA astronaut Andrew Morgan began by passing the cooling system to each other as they inched their way from the airlock to the Space Station’s robotic arm. Luca then attached himself to the arm and – aided by astronaut Jessica Meir who operated this from inside the Station – transported the system to the hard-to-reach worksite.

Luca rode the arm into position, seen in this image, and together with Drew screwed the new pump onto AMS. The system was powered on and Luca was moved to a different location by robotic arm for the swage operations. Luca did six swages before taking the robotic arm ride again to the underside of AMS for the last two where he finished the job.

The spacewalk was a success, with Luca and Drew finishing their delicate and unprecedented work ahead of schedule. They returned to the Space Station airlock ending the spacewalk at six hours and two minutes. A fourth and last spacewalk for AMS is planned at a later date.

Exoplanet satellite encapsulated

At Europe’s Spaceport in Kourou, French Guiana, ESA’s Characterising Exoplanet Satellite, Cheops, is being encapsulated into the flight adapter of the Soyuz-Fregat rocket that will lift it into space on 17 December.

It’s an intense period at the Spaceport, where engineers from ESA, Airbus and CNES have been preparing for launch since the satellite arrival in mid-October.

This sequence of photographs, taklen on 29 November, shows the Souyuz Arianespace System for Auxiliary Payloads (ASAP-S) being carefully and progressively aligned to Cheops, then lowered onto and finally mated to the conic adapter. The mechanical integration is completed by fastening the fixation bolts.

Cheops is ESA’s first mission dedicated to the study of extrasolar planets, or exoplanets. It will observe bright stars that are already known to host planets, measuring minuscule brightness changes due to the planet’s transit across the star’s disc.

The mission will target stars hosting planets in the Earth- to Neptune-size range, yielding precise measurements of the planet sizes. This, together with independent information about the planet masses, will allow scientists to determine their density, enabling a first-step characterisation of these extrasolar worlds. A planet’s density provides vital clues about its composition and structure, indicating for example if it is predominantly rocky or gassy, or perhaps harbours significant oceans.

The first small, or S-class, mission in ESA’s science programme, Cheops is a partnership between ESA and Switzerland, with a dedicated consortium led by the University of Bern, and with important contributions from 10 other ESA Member States.

Cheops paves the way for the next generation of ESA’s exoplanet satellites, with two further missions – Plato and Ariel – planned for the next decade to tackle different aspects of the evolving field of exoplanet science. Together, these missions will keep the European scientific community at the forefront of exoplanet research well beyond the next decade, and will build on answering the fundamental question: what are the conditions for planet formation and the emergence of life?

New maps of salinity reveal the impact of climate variability on oceans

30. November 2019 - 15:26

Since the saltiness of ocean surface waters is a key variable in the climate system, understanding how this changes is important to understanding climate change. Thanks to ESA’s Climate Change Initiative, scientists now have better insight into sea-surface salinity with the most complete global dataset ever produced from space.
