ABOUT THE SERIES: In our #EZScience video series with the National Air and Space Museum, NASA’s associate administrator for science Dr. Thomas Zurbuchen and Museum director Dr. Ellen Stofan talk about the latest in planetary science and exploration.
Join ESA astronauts Thomas Pesquet and Matthias Maurer at NASA’s Johnson Space Center in Houston, Texas, USA. In part one of this video series, the two astronauts compare notes on their journey to date as they prepare for missions to the International Space Station.
Though mission details and dates are yet to be confirmed, Thomas and Matthias are the next two European astronauts in line for flights. Thomas has flown to the International Space Station before, while Matthias will fly for the first time.
Prior to a mission, astronauts train extensively to ensure they are familiar with the vast array of systems and operations on board. In this video, the pair discuss how training for a second mission differs from a first mission, the challenges of training during a global pandemic, and how flying to the Station on US commercial crew vehicles may differ from flying on the Russian Soyuz spacecraft.
This video was filmed in June 2020. At that time, the platform Thomas and Matthias were standing on – in front of a full-scale mock-up of the International Space Station – was the only place at NASA’s JSC that they could interact without face masks. Despite this, the pair were required to maintain social distance at all times as a precaution.

Coffee + spacewalk = breakfast of champions. ✔️ Join us on Thursday, July 16, as NASA Astronauts Chris Cassidy and Robert Behnken venture outside the International Space Station. This will be the first spacewalk in a series of two which complete power upgrades outside the orbital lab.The duo plan to remove five of six older nickel-hydrogen batteries for the truss’ power system and install three new lithium-ion batteries, as well as accompanying hardware. Start your day with us, and set a reminder to watch! Coverage starts at 6 a.m. EDT.
ESA’s Solar Orbiter spacecraft has sent back its first images of the Sun. At 77 million kilometres from the surface, this is the closest a camera has ever flown to our nearest star. The pictures reveal features on the Sun’s exterior that have never been seen in detail before.
Launched on 10 February 2020, the spacecraft completed its commissioning phase and first close-approach to the Sun in mid-June. Since then, science teams have been processing and examining this early data.
The spacecraft is currently in its cruise phase, on its way to Venus, but will eventually get even closer to the Sun.

The first images from ESA’s Solar Orbiter, captured around the spacecraft’s first close pass of the Sun, some 77 million kilometres from its surface, are already exceeding expectations revealing interesting new phenomena on our parent star.
This animation shows a series of close-up views captured by the Extreme Ultraviolet Imager (EUI) at wavelengths of 17 nanometers, showing the upper atmosphere of the Sun, or corona, with a temperature of around 1 million degrees.
These images reveal a multitude of small flaring loops, erupting bright spots and dark, moving fibrils. A ubiquitous feature of the solar surface, uncovered for the first time by these images, have been called ‘campfires’. They are omnipresent minuature eruptions that could be contributing to the high temperatures of the solar corona and the origin of the solar wind.
Captured on 30 May 2020, when Solar Orbiter was roughly halfway between the Earth and the Sun, these are the closest views of the Sun ever taken, allowing EUI to see features in the solar corona of only 400 km across. As the mission continues, Solar Orbiter will go closer to the Sun and this will increase the instrument’s resolving power by a factor of two at closest approach.
The colour on this image has been artificially added because the original wavelength detected by the instrument is invisible to the human eye.
The circle in the lower left corner indicates the size of Earth for scale.
The extended grey shape visible at times moving across the field (00:00-00:25; 01:00-01:28; 01:50-02:00; 02:52-03:27) is not a solar feature but is caused by a sensor artefact.
Solar Orbiter is a space mission of international collaboration between ESA and NASA.

The first images from ESA’s Solar Orbiter are already exceeding expectations and revealing interesting new phenomena on the Sun.
This animation combines a series of views captured with several remote-sensing instruments on Solar Orbiter between 30 May and 21 June 2020, when the spacecraft was roughly halfway between the Earth and the Sun ¬– closer to the Sun than any other solar telescope has ever been before.
The red and yellow images were taken with the Extreme Ultraviolet Imager (EUI) in the extreme ultraviolet region of the electromagnetic spectrum, at wavelengths of 30 and 17 nanometers, respectively.
The close-up views by EUI show the upper atmosphere of the Sun, or corona, with a temperature of around 1 million degrees. With the power to see features in the solar corona of only 400 km across, these images reveal a multitude of small flaring loops, erupting bright spots and dark, moving fibrils. A ubiquitous feature of the solar surface, uncovered for the first time by these images, have been called ‘campfires’. They are omnipresent minuature eruptions that could be contributing to the high temperatures of the solar corona and the origin of the solar wind.
The EUI images are followed by three views based on data from the Polarimetric and Helioseismic Imager (PHI) instrument. The blue and red view is a ‘tachogram’ of the Sun, showing the line of sight velocity of the Sun, with the blue side turning to us and the red side turning away. The following view is a magnetogram, or a map of magnetic propertied for the whole Sun, featuring a large magnetically active region in the lower right-hand quadrant of the Sun. The yellow-orange view is a visible light image and represents what we would see with the naked eye: there are no sunspots visible because the Sun is displaying only low levels of magnetic activity at the moment.
On larger scales, the Metis coronograph blocks out the dazzling light from the solar surface, bringing the fainter corona into view. Metis observes the corona simultaneously in visible light (shown in green) and ultraviolet light (shown in red) for the first time with unprecedented temporal coverage and spatial resolution. These images reveal the two bright equatorial streamers and fainter polar regions that are characteristic of the solar corona during times of minimal magnetic activity.
On even grander scales, the Heliospheric Imager (SoloHI) telescope takes images of the solar wind – the stream of charged particles constantly released by the Sun into outer space – by capturing the light scattered by electrons in the wind. The first-light image from SoloHI is shown at the end, as a mosaic of four separate images from the instrument’s four separate detectors. In this view, the Sun is located to the right of the frame, and its light is blocked by a series of baffles; the last baffle is in the field of view on the right-hand side and is illuminated by reflections from the solar array. The partial ellipse visible on the right is the zodiacal light, created by sunlight reflecting off the dust particles that are orbiting the Sun. The signal from the solar wind outflow is faint compared to the much brighter zodiacal light signal, but the SoloHI team has developed techniques to reveal it. Planet Mercury is also visible as a small bright dot near the lower edge of the upper left tile.

NASA’s next Mars rover has a name – Perseverance. Like every exploration mission before, our rover is going to face challenges, and it’s going to make amazing discoveries.
The time at hand is hard. We have already surmounted many obstacles on our way to Red Planet, but as humans we will not give up. We will always persevere.
Targeted for launch in July 2020, NASA’s Mars Perseverance rover will search for signs of habitable conditions on Mars in the ancient past and for signs of past microbial life itself.
Meet the team designing and building the Psyche mission’s gamma ray and neutron spectrometer. This instrument on the spacecraft will detect, measure, and map Psyche’s elemental composition. It is mounted on a 6-foot (2-meter) boom to distance the sensors from background radiation created by energetic particles interacting with the spacecraft and to provide an unobstructed field of view. The team is based at the Applied Physics Laboratory at Johns Hopkins University and is led by Principal Investigator David Lawrence.

Ice and snow can be a hot topic when talking about climate. The polar regions are very fragile and can tell us a lot about how Earth’s climate is changing. Andrew Shepherd of the University of Leeds is a leading climate scientist working with ESA and NASA. In this episode he explains how we can separate the effects of weather versus climate from data records and the role of space in studying changes to our planet in real-time and in the future.
