February 7th: Astronomer Steve Anderson found one possible moon orbiting Saturn having an aldebo lower than 0.07 with an semi major axis of 1 410 167 km and might collide with Cassini spacecraft in this November.
February 8th: The satellite is confirmed and named 2015S S2. Calculations says that it won't collide with Cassini. Instead it will just pass the spacecraft with the minimum distance of 89m.
February 21st: Another research led by ESO indicates that Cassini will might pass way to close from Saturn because a little Gravitational pull might just effect the whole spacecraft's orbit. It is set to reach a perihelion just 7,650 above the clouds of Saturn and launched outside the planet's gravitational influence(Hill sphere). There is a slight chance for those things to happen:
Didn't get launched, but instead captured by the Titan(neighboring satellite) or Mimas(same here) 3%
Crash and create a crater on the moon 2%
Flyby of Neptune and Triton 1.87%
Flyby of Eris 1.15%
Revisit any of the inner solar system planets 0.87%
Crash into Saturn 0.14%
February 23th: New Horizons spacecraft begin observing Pluto.
March 6: Dawn orbiter begins to orbit Ceres. A minor satellite and a ring arc are discovered.
April: North Korea's secret plan, Kilong, secretly begins.
June 1st: Pakistan put a men in space.
June 4th: According to the new UN resolution, Palestine is given a full UN membership. The Isreali president, Reuven Livin, give another speech about how the Palestinians is not a country nor anything, blah blah, Palestine is Israeli territory, blah blah blah. Arabs celebrates.
June 23rd: New Horizons begin to directly observe Pluto as it begins to get really close.
June 27th: Cassini spacecraft is somewhat malfunctioning, says NASA. The camera and Infrared is not working and the resolution Is dropping by 2% per day.
