ISS: 20 years looking over Earth

2. November 2020 - 15:30

To mark the 20th anniversary of continuous habitation of the International Space Station, ESA commissioned two graphic artists to illustrate the Station from two perspectives. We spoke to the artists and asked them how they approached this challenge.

Human rights in space

2. November 2020 - 15:07
Image:

In this image taken in 2008, Expedition 18 crewmembers Sandra Magnus, Mike Fincke and Yury Lonchakov display the Universal Declaration of Human Rights inside the European Columbus laboratory of the International Space Station. This year, as the Station celebrates 20 years of operation, both serve as a reminder of humankind’s ability to come together for a common cause.

The documents were carried into space on Space Shuttle Endeavour on 15 November 2008 as part of a year-long calendar of celebrations to mark 60 years since the Declaration was first adopted by the United Nations General Assembly at the Palais de Chaillot in Paris, France. They are permanently stored in the European Columbus module, which was installed just months earlier, in February 2008.

Today marks 20 years since the first crew took up residence on the International Space Station. Since then, 240 people including 18 ESA astronauts have lived and worked on the orbital outpost, carrying out essential research to benefit life on Earth.

The now football field-sized feat of engineering started off with just three modules: the Russian Zarya cargo and Zvezda service modules and the US Unity module. It took 42 assembly flights for all the large modules and other pieces of the Station to be delivered – 37 were delivered on NASA space shuttles and five on Russian Proton/Soyuz rockets.

The European laboratory, Columbus, was launched to the Station in 2008 and the European-built Cupola window providing the 360-degree views of Earth that we know and love today was added in 2010.

The Space Station orbits Earth at around 27 580 km/h, meaning astronauts living and working on board experience 16 sunrises and 16 sunsets every 24 hours. It has hosted over 26 European missions and supported over 2700 international experiments to improve life on Earth and in space.

The next European to fly to the Space Station is ESA astronaut Thomas Pesquet. Thomas will fly to the Station for his Alpha mission in 2021, becoming the first European to fly on a SpaceX Crew Dragon spacecraft.

Monday 2 November, 2020 marks 20 years since the first crew took up residence on the International Space Station. Since then, 240 people including 18 ESA astronauts have lived and worked on the orbital outpost, carrying out essential research to benefit life on Earth.

In this clip, ESA astronauts Luca Parmitano, Alexander Gerst, Thomas Pesquet, Tim Peake, Andreas Mogensen, André Kuipers, Christer Fuglesang, Frank De Winne and Reinhold Ewald pay tribute to the Station. ESA Director General Jan Wörner and NASA Administrator Jim Bridenstine also speak about the Station’s significance for space exploration and international collaboration.

The next ESA mission to the International Space Station is set for 2021, when Thomas Pesquet will become the first European to fly on a SpaceX Crew Dragon spacecraft for his Alpha mission.

Copernicus Sentinel-6 measuring sea-levels using radar altimetry

This November the newest member of the EU’s Copernicus programme, Sentinel-6 Michael Freilich, will take to the heavens from Vandenberg Air Force Base in California. The satellite is named after NASA’s former Director of Earth Observation and is a radar altimetry mission to monitor sea-level rise, wave-height and windspeed.

The mission is a collaboration between ESA, the European Commission, EUMETSAT, NASA and NOAA, with support from the French space agency CNES. It will continue a three-decade-long time-series of radar altimetry missions that started with the Topex-Poseidon mission and was then followed by the Jason missions.

Vega-C and Ariane 6 are being developed by ESA to assure Europe’s independent access to space. The maiden flight for Vega-C is planned to take place in June 2021, that for Ariane 6 for the second quarter of 2022.

Solar cycle 25: the Sun wakes up

29. Oktoober 2020 - 17:30

The Sun has entered its 25th solar cycle and is about to wake up. For the last few years our star has been pretty sleepy, with few sunspots, bright flares or massive ejections of magnetised plasma emanating from its surface. This quiet period is known as the solar minimum, but things are starting to heat up again.

An ancient crater triplet on Mars

Mars is covered in intriguing scars – some of the most prominent being impact craters. A particularly unusual example is shown in this new image from ESA’s Mars Express: an ancient triplet comprising not one but three overlapping craters.

Philae’s second touchdown site discovered at ‘skull-top’ ridge

After years of detective work, the second touchdown site of Rosetta’s Philae lander has been located on Comet 67P/Churyumov-Gerasimenko in a site that resembles the shape of a skull. Philae left its imprint in billions-of-years-old ice, revealing that the comet’s icy interior is softer than cappuccino froth.

ESA seeking dust-proof materials for lunar return

27. Oktoober 2020 - 14:18

When humans return to the Moon they’ll have formidable challenge lying in wait: lunar dust. The talcum-like lunar regolith is considered the biggest operational problem facing Moon colonists. Within a few days of dust exposure, Apollo spacesuits suffered obscured visors, clogged mechanisms and eroded suit layers. So an ESA team is looking into novel material options to serve as the basis of future spacesuits or protect rovers or fixed infrastructure.

A human endothelial cell that was flown to the International Space Station and returned to Earth for analysis is helping researchers keep astronauts healthy in space.

Endothelial cells line our blood vessels and help contract and expand the vessels as needed and so are instrumental in maintaining pressure and a healthy body.

The Endothelial Cells experiment flew to the International Space Station in 2015 to understand how the cells react to weightlessness.

Blood flow changes in space because gravity no longer pulls blood towards astronauts’ feet. By understanding the underlying adaptive mechanisms of how our bodies respond to weightlessness, the experiment aims to develop methods to help astronauts in space while showing possibilities for people on Earth – our endothelial cells become less effective with age – to live longer and healthier lives.

Cultured human endothelial cells were grown in space in ESA’s Kubik incubator for one week and then ‘frozen’ chemically for analysis back on Earth.

As expected, the cells started to express genes differently to cells that stayed on Earth, attaching and moving differently while in space. After careful comparison in the lab, researchers have published a paper with first results confirming that the cells suffer stress from spaceflight.

Importantly, the research is showing how the cells adapt to the stress and provides clues as to how we could help endothelial cells to stay healthy in space and in patients on Earth.

For the curious, the image shows human capillary endothelial cells HMEC-1, red: b-catenin, blue: nuclei, using a Fluorescence Zeiss PALM MicroBeam Microscope at 63x magnification.
