Announced start slot for exoplanet mission

The characterizing exoplanet satellite Cheops will be launched from 15 October to 14 November 2019.

Cheops will take off from the European spaceport in Kourou with a Soyuz rocket operated by Arianespace and launch into space together with a satellite is part of the Italian Cosmo-SkyMed constellation. The two satellites separate soon after the rise in their own orbits. Cheops operate in a near-earth orbit at an altitude of 700 km.

The satellite observes single bright stars that harbor, in particular, exoplanets in the Earth-to-Neptune size range. Cheops know exactly when and where to catch the exoplanet when it shoots over the disc of the host star.

Its ability to observe multiple transits of each planet will allow scientists to achieve high-precision transit signatures needed to measure the size of small planets.

The combination of exact and exact sizes determined by Cheops with masses determined from other measurements is used to determine the bulk density of the planets, thereby limiting their composition; Together with information about the host stars and the orbits of the planets, they will provide important insights into the genesis and evolutionary history of planets ranging in size from super earth to neptune. ESA's Dutch technical center is currently conducting final tests at Airbus Defense and Space in Spain before it can be released for launch in early 201


To inspire different audiences for this exciting mission, Cheops will be running two plaques bearing thousands of miniaturized drawings of schoolchildren, while the missile cladding will feature a colorful design that was selected in a public competition earlier this year for graphic designers was meant.

New amateur archiving database Astronomer Exoplanet Data

MA (SPX) November 19, 2018

At their annual meeting at the Lowell Observatory in Flagstaff, Arizona, the American Association of Variable Star Observers announced a new exoplanet database containing long-term information on interesting Planets orbiting stars are archived outside the Solar System, enabling powerful collaborations between professional and amateur astronomers.

Although it is difficult to directly observe exoplanets directly, data about them can be collected by pointing to tell-tale variations in the light of the … read more
