Conferència: El proper viatge a l’illa de Mallorca.

Per Miquel Amblàs, professor, i membre de l’AAd’O.

Comentarem detalladament el viatge a Mallorca que farem de l’1 al 4 de maig, centrat en l’Observatori Astronòmic (OAM), on visitarem l’Àrea d’Investigació i la col·lecció de meteorits, el planetari i l’espai d’observació de l’Àrea de Divulgació. També parlarem de les visites als altres indrets de l’illa, tots de remarcable interès històric, cultural i paisatgístic.

Watch live: final #SpacewalkforAMS

Luca photographed by Oleg Skripochka from inside the International Space Station

ESA astronaut Luca Parmitano and NASA astronaut Andrew Morgan will exit the International Space Station airlock together for the fourth time Saturday 25 January. It is the ninth spacewalk for Expedition 61 – the most spacewalks ever performed during a single Space Station expedition – and the last in a complex series to maintain the Alpha Magnetic Spectrometer AMS-02.

Galileo now replying to SOS messages worldwide

Galileo

As well as providing global navigation services, Europe’s Galileo satellite constellation is contributing to saving more than 2000 lives annually by relaying SOS messages to first responders. And from now on the satellites will reply to these messages, assuring people in danger that help is on the way.

Taal volcano blanketed by ash

Image:

The Philippines’ Taal volcano erupted on 12 January 2020 – spewing an ash plume approximately 15 km high and forcing large-scale evacuations in the nearby area.

This almost cloud-free image was captured today 23 January at 02:20 GMT (10:20 local time) by the Copernicus Sentinel-2 mission, and shows the island, in the centre of the image, completely covered in a thick layer of ash.

This optical image has also been processed using the mission’s short-wave infrared band to show the ongoing activity in the crater, visible in bright red. Ash blown by strong winds can be seen in Agoncillo, visible southwest of the Taal volcano. Ash has also been recorded in other areas of the Batangas province, as well as Manila and Quezon.

According to The Philippine Institute of Volcanology and Seismology bulletin published today, sulphur dioxide emissions were measured at an average of around 140 tonnes. The Taal volcano still remains on alert level four, meaning an explosive eruption is possible in the coming hours or days. The highest alert level is five which indicates an eruption is taking place.

According to the National Disaster Risk Reduction and Management Council, over 50 000 people have been affected so far. In response to the eruption, the Copernicus Emergency Mapping Service was activated. The service uses satellite observations to help civil protection authorities and, in cases of disaster, the international humanitarian community, respond to emergencies.

Spacewalks, science and Beyond

Spacewalk season continues on the International Space Station. ESA astronaut Luca Parmitano and NASA astronaut Andrew Morgan are getting ready to step outside the Quest airlock for their fourth and final time together on Saturday. But before they do, we look back at an action-packed fortnight of science and operations on the world’s only orbital outpost.

Second space data highway satellite set to beam

EDRS-C

The second satellite in the European Data Relay System has reached its intended orbit and completed its in-orbit tests.

Dubbed the “SpaceDataHighway” by its commercial operator Airbus, EDRS uses innovative laser technology to enable Earth-observation satellites to deliver their information to users on the ground in near real-time, accelerating responses to emergency situations and spurring the development of new services and products.

EDRS-C is the second satellite in the system and was launched on 6 August.
