... planet’s orbital energy. This makes the journey very long but at the end the spacecraft reaches the comet with the same orbital velocity as the nucleus, and is able to fly in formation with it around the Sun. The initial idea was even more ambitious...
... mission operations of all ESA scientific missions dealing with the Sun and the Solar System. As part of this job I was still in charge of the Rosetta mission, but I had to leave the spacecraft operations manager role. Fortunately at this time Venus...
... and Earth, while the sensitivity of WFIRST extends outward and the sensitivity of Kepler extends inward. More than 75 percent of the known exoplanets have orbital periods less than that of Mercury, the closest planet to the Sun in our solar system...
... Parker Solar Probe, launched in 2018, will set a new speed record of 200 km/s by taking advantage of the enormous gravitational pull of the Sun. But even this translates to a travel time to Proxima Centauri of over 6,000 years. Such a mission would...
...that of the Sun, has been found by astronomers just two billion years after the Big Bang. Its overwhelming size has earned it the nickname Hyperion and it is the largest and most massive structure to be found so early in the formation of the Universe...
