Horizons mission time-lapse – from Alaska to the Andes

Ever wondered what it feels like to fly from Alaska to the Andes in 260 seconds? ESA astronaut Alexander Gerst captured this timelapse footage of Alaska, the USA and South America while orbiting Earth on board the International Space Station.

This timelapse is made up of 6,375 images shown 12.5 times faster than actual speed. Music is Our Oasis by Miriam Speyer, sourced from Audio Network Limited.

What is… an eclipse?

What is a lunar eclipse? What is a solar eclipse? This short video explains the difference between these regularly occurring events that can be observed from Earth.

The video uses a mix of ground- and space-based imagery of eclipses, including footage from the International Space Station, ESA’s Proba-2 satellite and the Japanese-led Hinode satellite.

Remember: never look directly at the Sun, even when partially eclipsed, without proper eye protection such as special solar eclipse glasses, or you risk permanent eye damage.

Horizons science – airway monitoring

In space, there is no such thing as waiting for the dust to settle. Rather than drifting to the ground, dust particles float about continuously and can irritate eyes and lungs.

By recording how much nitrogen oxide he exhales in space as part of the Airway Monitoring experiment, ESA astronaut Alexander Gerst is helping researchers understand how to monitor, diagnose and treat lung conditions like asthma here on Earth.

The findings of this monitoring will also be crucial to exploring the Moon and even Mars – where dust is considered even more toxic and must be carefully managed for astronauts’ health.

The Airways Monitoring experiment has been underway since 2015. Later in the Horizons mission Alexander will repeat the experiment in the reduced pressure of the airlock.

Highlights of Galileo 23–26 launch

Galileo satellites 23–26 were launched into orbit on Wednesday 25 July 2018 atop Ariane 5 Flight VA244 from Europe’s Spaceport in Kourou, French Guiana. This marked Europe’s 99th Ariane 5 launch. Their launch campaign commenced back in May, with the arrival of the first pair of satellites. The second pair followed in early June. The video shows their preparation for launch, integration with the launcher and its final journey to the launch pad, followed by liftoff and separation of the satellites into their target orbit.

Good evening, Kraftwerk / Guten Abend Kraftwerk, guten Abend Stuttgart!

On 20 July 2018 around 21:50 local time, ESA astronaut Alexander Gerst welcomed the legendary electronic band Kraftwerk and 7500 visitors to the Jazz Open Festival on Stuttgart’s Schlossplatz – live from the International Space Station, where he will live and work until mid-December 2018. During the call with space, Kraftwerk founding member Ralf Hütter and Alexander played a special duet version of the track Spacelab, for which Alexander had a tablet computer configured with virtual synthesizers on board. With thanks to Kraftwerk for sharing this video footage.

So begrüßte ESA-Astronaut Alexander Gerst am 20. Juli 2018 um 21:50 Uhr Ortszeit die legendären Elektro-Pioniere Kraftwerk sowie 7500 Besucherinnen und Besucher des Jazz Open-Festivals auf dem Stuttgarter Schlossplatz – und zwar live von der Internationalen Raumstation ISS, auf der er noch bis Mitte Dezember 2018 lebt und arbeitet.

Kraftwerk-Gründungsmitglied Ralf Hütter und Alexander Gerst spielten eine spezielle Version des Tracks Spacelab im Duett an, für das Gerst eigens einen mit virtuellen Synthesizern konfigurierten Tablet-Computer an Bord hatte.

Shaking Orion’s solar wings

Testing the solar wings of the European service module that will provide power, water, air and electricity to NASA’s Orion Moon module.

The solar arrays Orion will use to produce electricity are tested at ESA’s technical heart in the Netherlands. Folded for launch, the fragile solar panels need to survive the rumbling into space aboard the most powerful rocket ever built, NASA’s Space Launch System.
Orion’s solar panels will be folded inside the rocket fairing on the first leg of the trip around the Moon. Once released from the rocket they will unfold and rotate towards the Sun to start delivering power.
To make sure the solar panels will work after the intense launch, ESA engineers are putting them through rigorous tests that exceed what they will experience on launch day. This includes vibrating them on a shaking table and placing them in front of enormous speakers that recreate the harsh launch conditions.

Orion will eventually fly beyond the Moon with astronauts, the first time a spacecraft will support humans with European hardware will also be the farthest humans ever travel from Earth. The first mission – without astronauts – is getting ready for launch in 2019.

Space Bites: Resources beyond Earth | Angel Abbud Madrid

Humans will have to breath, drink and eat while living on the Moon. They will need energy to perform tasks using their robotic companions and materials to build structures. For a sustainable approach to space exploration these resources cannot be carried from Earth but have to be found on the Moon itself.

Angel Abbud Madrid is the Director of the Center for Space Resources at the Colorado School of Mines (CSM), where he leads a multidisciplinary research programme on the human and robotic exploration of space and the utilisation of its resources. He is also the Director of the CSM Space Resources Program, the first academic programme in the world focused on educating scientists, engineers, economists, entrepreneurs and policymakers in the developing field of space resources. 

Space Bites hosts the best talks on space exploration from the most inspiring and knowledgeable speakers from the field. Held at the technical heart of the European Space Agency in the Netherlands, the lectures are now also available on YouTube. If you want to know about the present and future challenges of ESA, stay tuned for more.
