Bringing samples from Mars is the logical next step for robotic exploration and it will require multiple missions that will be more challenging and more advanced than any robotic missions before. Accomplishments in robotic exploration in recent years have increased confidence in success – multiple launches will be necessary to deliver samples from Mars.
ESA is working with NASA to explore mission concepts for an international Mars Sample Return campaign between 2020 and 2030.
Three launches will be necessary to accomplish landing, collecting, storing and finding samples and delivering them to Earth.
NASA’s Mars 2020 mission will explore the surface and rigorously document and store a set of samples in canisters in strategic areas to be retrieved later for flight to Earth.
Two subsequent missions are foreseen to achieve this next step.
A NASA launch will send the Sample Retrieval Lander mission to land a platform near the Mars 2020 site. From here, a small ESA rover – the Sample Fetch Rover – will head out to retrieve the cached samples.
Once it has collected them in what can be likened to an interplanetary treasure hunt, it will return to the lander platform and load them into a single large canister on the Mars Ascent Vehicle (MAV). This vehicle will perform the first liftoff from Mars and carry the container into Mars orbit.
ESA’s Earth Return Orbiter will be the next mission, timed to capture the basketball-size sample container orbiting Mars. The samples will be sealed in a biocontainment system to prevent contaminating Earth with unsterilised material before being moved into an Earth entry capsule.
The spacecraft will then return to Earth, where it will release the entry capsule for the samples to end up in a specialised handling facility.
ESA and NASA are exploring the concepts for these missions, with ESA assessing the Sample Fetch Rover and Earth Return Orbiter. These will provide input to ESA’s 2019 council at ministerial level, where approval will be sought for the missions.

This graphic summarises significant measurement attempts of methane at Mars. Reports of methane have been made by Earth-based telescopes, ESA’s Mars Express from orbit around Mars, and NASA’s Curiosity located on the surface at Gale Crater; they have also reported measurement attempts with no or very little methane detected. More recently, the ESA-Roscosmos ExoMars Trace Gas Orbiter reported an absence of methane, and provided a very low upper limit.
In order to reconcile the range of results, which show variations in both time and location, scientists have to understand better the different processes acting to create and destroy methane.

Technology image of the week:
ESA Director General Jan Woerner joined the Agency’s Director of Technology, Engineering and Quality at a special award ceremony for ESA’s inventors.
The ceremony took place at ESA’s technical centre in the Netherlands on 31 May, recognising inventors for their contributions during the past two years, leading to 13 patents.
“It is important to recognise the outstanding results of our ESA staff and contractors,” commented the Director General. “Through their creative work they help to maintain Europe’s competitiveness in the space industry.
“Furthermore, as ambassadors of their ideas, ESA’s inventors support the transfer of these patented technologies to completely new sectors, thereby demonstrating the benefit of space technology for society as a whole.”
In total, ESA’s patent portfolio consists of around 300 patented inventions and about 150 applications in progress, across a diverse variety of technical sectors. This portfolio is managed by the Agency’s Technology Transfer Programme Office, working to find terrestrial uses for advanced space technology.
Among the inventions awarded this time was a compression algorithm specially designed by David Evans to serve data housekeeping aboard satellites: it operates so rapidly that it can compress individual data packets as they are generated.

Un fin de semana en una casita en el río...Donde no había nada más para fotografiar que justamente el río, árboles y niños, que ya me miraban con cara de pocos amigos...
Aún no llegó la primavera a Argentina, por lo tanto, no había más flores que este pequeño ramito al lado de un árbol y otra flor que encontré abandonada por ahí, en una mini selva...
Soy horrible fotografiando paisajes, de todas maneras, saqué muchas fotos intentando practicar un poco y conocer un poquito más mi cámara ( si me animo subo alguna).
Quería incluir un poco de color a las fotos y todo lo que encontré para ello, fue una manzana que rescaté de las "garras" de los niños que arrasaban con todo.
Me aferré a ella como la [ ARDILLA DE LA ERA DEL HIELO A SU BELLOTA ] y la usé para hacer esta serie de fotos, que intentan ser algo así como una historieta, donde la protagonista es la esa maldita manzana y la actríz secundaria es una pequeña linternita que uso como lúz de lectura
Locuras mías de un fin de semana "campestre", intentando sobrevivir sin mi notebook :P
CONTINUARÁ...
esa luz,
es tu sombra…
Quiéreme entera...
Si me quieres, quiéreme entera,
no por zonas de luz o sombra...
si me quieres, quiéreme negra,
y blanca, y gris, y verde, y rubia,
quiéreme día,
quiéreme noche...
¡Y madrugada en la ventana abierta!
si me quieres, no me recortes:
¡quiéreme toda... o no me quieras!

They have a passion for space and are some of the best engineers anywhere, conducting flight operations for exploration, technology and Earth missions worth billions of euros. Above all, ESA’s flight directors and spacecraft operations managers are team leaders, working to motivate people and manage complex systems on the cutting edge of exploration.
This photo, taken 2 November, shows 25 of the 40 spacecraft operations managers and flight directors assigned to missions this year. Those not present were away on duty travel, working off site or overseeing live operations or simulation training.
At the moment, ESA’s control centre in Darmstadt, Germany, is seeing a historically intense pace of flight operations. There are four training campaigns in progress for Galileo-11/12, LISA Pathfinder, Sentinel-3A and ExoMars to prepare teams for upcoming launches, while flight operations for 15 satellites plus three more controlled from ESA’s Redu Centre in Belgium continue.
The launch and operation of any ESA mission requires a multidisciplinary ‘team of teams’ working across the agency and supported by industry and academia. However, it is the spacecraft operations manager, the ubiquitous SOM, who is immediately responsible for day-to-day flight activities, planning and execution, and for solving the myriad problems that inevitably arise when complex satellites voyage into space.
An SOM is assigned to each current and upcoming ESA mission, and his/her first task is to build the Flight Control Team, comprising spacecraft engineers and technicians who specialise in each of the mission’s technical areas, including attitude and orbit control, power and thermal and onboard computer systems.
The Flight Control Teams are supported by experts working in areas such as flight dynamics, software and ground tracking stations.
Teams are multidisciplinary and multicultural, and provide oversight for their missions 24 hours per day, 365 days per year.

La cuestión seria es que estamos acabando el mes de noviembre y la cosa no está boyante, que digamos... Aunque a fuerza de ser sincero uno ya no sabe si achacar la escasez a los débiles tráficos o a la persona que debería fotografiarlos. Puesto en cifras, y para que se me entienda, dos mercantes en 25 días...
Cuando la veteranía es un grado, o un saco de patatas según se mire, la secuencia es aferrarse a la ley del mínimo esfuerzo y máxima comodidad. Te asignas un día de la semana, aguardas y cuando llega asomas la patita por entre las sábanas y compruebas que hace frío. Y piensas que con lo bien que se está en la camita va a salir a vía Rita la cantaora... Y cuando hace calor pasas porque temes que se derrita el poco seso que te queda.
Sea como fuere dejas que toda la noche vayan pasando pájaros sin que ello te inmute.
Puede que todo ello sea la razón de la insistente subida de churrifotos a mi galería. Sin embargo no es menos cierto que quiero demostrar que aún mantengo, de alguna forma, la ilusión de décadas pasadas. Por eso, y entre retazos del ayer, incorporo algo actual dentro de la panoplia de fotos.
Lo de siempre. Alrededor de las ocho abro los ojos, compruebo que la luz entra por entre la rendijas de la persiana y el pensamiento de horas anteriores se disipa. Se está tan bien bajo la colcha... Pero no es cuestión de permanecer agazapado hasta la hora de comer, así que a media mañana trinco el bonobús y me acerco hasta este punto. De lo que se trata es de quitarse el mono de encima, evidentemente.
De camino al punto, de repente, me invade la zozobra. "Hoy es viernes y están programados paros tanto en Renfe como en Adif. Buena me espera..." A pesar de ello quiero pasar algo más de una hora y ver lo que se cuece. Y se coció este largo portaautomóviles cargado de Kuga encaminándose a Ford. Oye, y agradecido porque no es demasiado común ver uno de estos puro de cabo a rabo; ya sabéis que lo normal es que vayan en forma de mixtos junto a los azules y los MC.
Total, que para qué más. Recojo los bártulos y a casa de nuevo, dispuesto a que me den de comer y luego dormir la siesta... Por Dios!!, no iban a ser todo trenes...

Go with the (silicate) flow
Webb’s observations of the protostar EC 53 uncovered long sought-after evidence to explain why comets at the edge of our solar system contain crystalline silicates. These comets are found in the ultracold Kuiper Belt and Oort Cloud yet these minerals require intense heat to form. Scientists have shown in the past that these minerals also exist in protoplanetary disks around other stars - but they weren’t sure how they got there.
Webb showed for the first time that the hot, inner part of the disk of gas and dust surrounding a very young, actively forming star is where crystalline silicates are forged. Webb also revealed a strong outflow that is capable of carrying the crystals to the outer edges of this disk, cold and distant locales, where comets may eventually form. Compared to our own fully formed, mostly dust-cleared solar system, the crystals would be forming approximately between the Sun and the Earth. These silicates are indeed common minerals found on Earth.
Researchers mapped how the crystals move throughout the system, showing how the star creates and distributes these particles, which are each smaller than a grain of sand. In this image taken by Webb’s NIRCam, one set of winds and scattered light from EC 53’s disk is shown as a white semi-circle angled toward the right.

How methane is created and destroyed on Mars is an important question in understanding the various detections and non-detections of methane at Mars, with differences in both time and location. Although making up a very small amount of the overall atmospheric inventory, methane in particular holds key clues to the planet’s current state of activity.
This graphic depicts some of the possible ways methane might be added or removed from the atmosphere.
One exciting possibility is that methane is generated by microbes. If buried underground, this gas could be stored in lattice-structured ice formations known as clathrates, and released to the atmosphere at a much later time.
Methane can also be generated by reactions between carbon dioxide and hydrogen (which, in turn, can be produced by reaction of water and olivine-rich rocks), by deep magmatic degassing or by thermal degradation of ancient organic matter. Again, this could be stored underground and outgassed through cracks in the surface. Methane can also become trapped in pockets of shallow ice, such as seasonal permafrost.
Ultraviolet radiation can both generate methane – through reactions with other molecules or organic material already on the surface, such as comet dust falling onto Mars – and break it down. Ultraviolet reactions in the upper atmosphere (above 60 km) and oxidation reactions in the lower atmosphere (below 60 km) acts to transform methane into carbon dioxide, hydrogen and water vapour, and leads to a lifetime of the molecule of about 300 years.
Methane can also be quickly distributed around the planet by atmospheric circulation, diluting its signal and making it challenging to identify individual sources. Because of the lifetime of the molecule when considering atmospheric processes, any detections today imply it has been released relatively recently.
But other generation and destruction methods have been proposed which explain more localized detections and also allow a faster removal of methane from the atmosphere, closer to the surface of the planet. Dust is abundant in the lower atmosphere below 10 km and may play a role, along with interactions directly with the surface. For example, one idea is that methane diffuses or ‘seeps’ through the surface in localized regions, and is adsorbed back into the surface regolith. Another idea is that strong winds eroding the planet’s surface allows methane to react quickly with dust grains, removing the signature of methane. Seasonal dust storms and dust devils could also accelerate this process.
Continued exploration at Mars – from orbit and the surface alike – along with laboratory experiments and simulations, will help scientists to better understand the different processes involved in generating and destroying methane.

Soon after the start of the NASA/ESA/CSA James Webb Space Telescope’s science operations, astronomers noticed something unexpected in the data: red objects that appear small on the sky, located in the distant, young universe. Come to be known as “little red dots” (LRDs), this intriguing class of objects is not well understood at present, sparking new questions and prompting new theories about the processes that occurred in the early universe.
A team of astronomers sifted through James Webb Space Telescope data from multiple surveys to compile one of the largest samples of “little red dots” (LRDs) to date. The team started with the Cosmic Evolution Early Release Science (CEERS) survey before widening their scope to other extragalactic legacy fields, including the JWST Advanced Deep Extragalactic Survey (JADES) and the Next Generation Deep Extragalactic Exploratory Public (NGDEEP) survey.
From their sample, they found that these mysterious red objects that appear small on the sky emerge in large numbers around 600 million years after the big bang and undergo a rapid decline in quantity around 1.5 billion years after the big bang. Spectroscopic data of some of the LRDs in their sample, provided by the Red Unknowns: Bright Infrared Extragalactic Survey (RUBIES), suggests that many are accreting black holes. However, further study of these intriguing objects is required.
[Image description: Six Webb images of little red dots are combined in a two-row mosaic. Each little red dot is centered within a square frame and lies against the black background of space. Each dot has a yellow-white circular core surrounded by a red, fuzzy ring. White text in the top left corner of each box lists the source’s name from the Webb surveys, and its redshift. From left to right, the top row reads CEERS 14448, z = 4.75; NGDEEP 4321, z = 8.92; and PRIMER-COS 10539, z = 7.48. The bottom row reads CEERS 20320, z = 5.27; JADES 9186, z = 4.99; and PRIMER-UDS 17818, z = 6.40.]
