Desert trial for ESA Mars rover ....

 

Next week will see ESA’s most ambitious planetary rover test yet. Robotic exploration of a Mars-like desert in South America will be overseen from the UK, providing experience for future missions to the Red Planet.

The rover faces the desolate Atacama Desert in northern Chile, one of the closest terrestrial matches for Mars. Among the driest places on Earth, it lacks any vegetation and its red–brown soil and rocks make it look even more like Mars.

Missione Ariane VA241 ... che cosa è andato storto ...

Arianespace vient de livrer les conclusions de l'enquête mise en place après la dernière mission du lanceur lourd européen, durant laquelle une déviation trajectoire avait entraîné la mise à poste des charges utiles sur une orbite trop inclinée.

Alain Charmeau, le président d’ArianeGroup, en avait touché deux mots aux députés le 21 février à l’Assemblée nationale : la cause de la défaillance du lanceur Ariane 5 ECA lors du vol VA 241 du 25 janvier dernier est désormais « parfaitement » identifiée, et la commission d’enquête indépendante mise en place dès le lendemain de l’incident, sous l’égide de l’Agence spatiale européenne , a rendu ses conclusions et ses recommandations le 22 février.

D’après le communiqué d’Arianespace diffusé ce 23 février (*), l’enquête a démontré que « l’anomalie de trajectoire résulte d’une valeur erronée dans la spécification de mise en œuvre des deux centrales inertielles du lanceur.

The new Spanish Prime Minister has announced his intention to appoint Spanish ESA astronaut Pedro Duque as Minister for Science, Innovation and Universities.

“It is a great privilege to be able to transfer my experience as an astronaut, project manager and space sector CEO to my new role in the government,” says Duque.

“I am looking forward to increasing awareness in science and technology among Spanish citizens.”

La foto del secolo ?

The first direct image of a black hole was captured by the Event Horizon Telescope (EHT). 
Using an array of radio telescopes during a 2017 global campaign, astronomers observed the black hole at the centre of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster. 
Heino Falcke, Chair of the EHT Science Council, and Monika Moscibrodzka, astrophysicist at Radboud University, present the discovery.
