House Hearings Fail to Tap NASA’s Full Potential

Yesterday the  U.S. House of Representatives  Subcommittee on Space held a hearing entitled “Exploring Our Solar System: The ASTEROIDS Act as a Key Step Planetary science“. I was curious about this act and expected the hearing to focus on interesting new ways to motivate private companies to design, launch, and operate space missions, and further the study of our Solar System.

Des mondes similaires au nôtre cachés dans des centaines d’exoplanètes ? SETI PR en Francais

Communiqué de presse de l’Institut SETI et de CASCA
Monday, June 09 2014 – 12:15pm, PDT

Mountain View, CA –
Cette année a été intense pour les chasseurs d’exoplanètes, ces planètes autour d’autres étoiles. Une équipe d’astronomes de l’Institut SETI et du centre de recherche de la NASA Ames a découvert 715 nouvelles exoplanètes enfouies dans les données du télescope spatial Kepler. Ces nouveaux mondes qui tournent autour de 305 étoiles différentes, constituent des systèmes planétaires multiples, similaires a notre système solaire, lui-même constitué de huit planètes. L’annonce de cette découverte a été suivie par une nouvelle encore plus importante dans le monde de l’astronomie : la même équipe a annoncé la découverte de Kepler 186f, une planète de la même taille que la Terre qui tourne autour de son étoile dans la zone dite habitable. Cette decouverte constitue une étape essentielle vers la détermination de l’existence de planètes de type Terre dans la Voie Lactée.

54 years of space exploration: an updated map that you must see

National Geographic asked 5W Infographics to update its 50 Years of Exploration graphic, a classic that I use often in my talks to illustrate our space exploration program and its focus on the inner part of the solar system.

The updated version, renamed “Cosmic Journey“, is spectacular, better organized and easier to follow than its predecessor. It has been updated to include new missions sent over the past 4 years. The new color code includes the paths of failed, as well as successful, missions and also the nation that led them.

First Discovery Of An Earth-Sized Planet In The Habitable Zone

Source: SETI Institute Press-release

MOUNTAIN VIEW, CA – For the first time, an Earth-sized planet has been found in the habitable zone of its star. This discovery not only proves the existence of worlds that might be similar to our own, but will undoubtedly shape future investigations of exoplanets that could have terrestrial surface environments.

China joined the interplanetary club by successfully imaging the asteroid Toutatis

This exceptional result was brought to my attention late on Friday evening, but it clearly deserves a short post on this blog. Chang’E 2, a chinese mission dedicated to the exploration of the moon was recycled to explore the Near-Earth Asteroid (4179) Toutatis  and succeeded.

Chang'e 2 images of (4179) Toutatis captured at 93–240 km distance between 16:30:09–16:30:24, maximum resolution 10 meters/pixel

New NASA Institute – The NASA-Armstrong Space Exploration Institute?

NASA made a request for input to name the new NASA Science and Exploration Institute.  You can propose your own name on this web site. I just submitted a proposed name for this virtual institute, which will include other destinations beyond the Moon, stemming from NASA’s flexible path strategy for human exploration. I propose to name this new

Thoughts about a beautiful NASA video – Save Our Science

Today I am feeling inspired and motivated. It could easily have not been the case since the day started with a massive crash of my email inbox, a difficult review of a recently submitted paper, and some issues with my simulation that I am planning to present at the ACM conference next week – not to mention a lack of sleep. Still, all of this became irrelevant when I watched NASA’s new promotional video attached below.

A Snapshot of Exoplanet Study

The study of exoplanets is without any doubt the most active and disrupting field in today astronomy. I had often blogged about it since it is my little obsession. Unfortunately, I have a hard time to keep up with the amount of discoveries and announcements being made every week over the past 3 years. This post is a snapshot of the recent study of exoplanets: what we know, what have been recently discovered and what is coming soon.
