A team of European scientists working with COROT have discovered an exoplanet orbiting a star slightly more massive than the Sun. After just 555 days in orbit, the mission has now observed more than 50 000 stars and is adding significantly to our knowledge of the fundamental workings of stars. The latest discovery, COROT-exo-4b is an exoplanet of about the same size as Jupiter. It takes 9.2 days to orbit its star, the longest period for any transiting exoplanet ever found.

Scientists and engineers are preparing ESA's Mars Express for several close fly-bys of the Martian moon Phobos. Passing within 100 km of the surface, Mars Express will conduct some of the most detailed investigations of the moon to date. The series of fly-bys will take place between 12 July and 3 August. During the second encounter, the spacecraft will fly within 273 km of the surface. Six days later, Mars Express will close to within just 97 km. Mars Express to Rendezvous with Martian Moon Phobos.

On Oct. 9, 2007, XMM-Newton was turning from one target to another when it passed across a bright source of X-rays that no one was expecting. The source was not listed in any previous X-ray catalog, yet the mysterious object was lighting up XMM-Newton’s view of the cosmos.

The first robotic mission to return samples to Earth from Mars took a further step toward realisation, with the recent publication of a mission design report by the iMARS Working Group. The report defines key elements of the future internationally-funded mission, involving the cooperation of ESA, NASA and other national agencies. iMARS, which stands for the International Mars Architecture for the Return of Samples is a committee of the International Mars Exploration Working Group made up of scientists, engineers, strategic planners, and managers. The report, which comes after months of deliberation, outlines the scientific and engineering requirements of such an international mission to be undertaken in the timeframe 2020-2022.

Repair of Launch Pad 39A's flame trench is right on schedule. All materials needed for the refurbishment have arrived and fireproofing begin this week, with the application of Fondu Fyre, a heat resistant concrete developed during the Apollo space program. The STS-125 flight is the final shuttle mission to the Hubble Space Telescope. NASA astronauts will install new instruments, gyros, batteries and other components crucial to the telescope's continued success through the year 2013.

XMM-Newton has discovered an exploding star in the Milky Way. Usually that would be important in itself, but this time there is a special twist. Calculations show that the explosion must have been clearly visible to the unaided eye but was missed by the legions of star watchers around the planet. On 9 October 2007, ESA's orbiting X-ray observatory XMM-Newton was turning from one target to another. As it did so, it passed across a bright source of X-rays that no one was expecting. The source was not listed in any previous X-ray catalogue, yet XMM-Newton was receiving some 50 X-rays every second from this mysterious object.
