NASA's OSIRIS-REx spacecraft successfully used Earth’s gravity on Friday to slingshot itself on a path toward the asteroid Bennu, for a rendezvous next August. Read a wrap-up of the gravity assist here!

Today at 6.52 PM CEST, look up to the sky and wave at NASA's OSIRIS-REx Asteroid Sample Return Mission! The probe will make its closest approach to Earth in a gravity assist to slingshot out to its target, asteroid 101955 Bennu which it will reach in August 2018, returning with samples in 2023. A very exciting mission and we are already looking forward to welcoming you back in 6 years!

NASA reports Hubble Space Telescope discovery that asteroid belt object 2006 VW139 is in fact two asteroids with comet-like features orbiting each other.
Just like comets, both asteroids are spewing water vapour into space and at almost 100km are orbiting much further apart from one another than asteroids of that size usually would.

If you're lucky enough to have a night sky free of clouds tomorrow, don't forget to turn your eyes skywards to see Asteroid 3122 Florence pass us at 7 million km. The 4.4 km wide asteroid will be visible with telescopes on Thursday night. If you don't own a telescope, don't despair: Its passage will be streamed live by Asteroid Day friend Gianluca Masi and his Virtual Telescope Project, starting at 9.30 PM CEST on the 31st August. Follow the link below!

Researchers use computer model to study the asteroid that wiped out the dinosaurs' effect on world climate 66 million years ago. Their findings, published in 'Proceedings of the National Academy of Sciences', show that photosynthesis was effectively shut down on Earth for over a year with light during the day only reaching the same brightness as during full moon nights and temperatures over land dropping by 28°C.

While everyone will be excitedly looking upwards for the #GreatAmericanEclipse, 2 of the NASA's WB-57F research jets are going to follow the moon's shadow to observe the sun's corona, searching among other things for vulcanoids, a hypothesised family of asteroids thought to orbit between the Sun and Mercury. #SolarEclipse2017 Fingers crossed! https://www.nasa.gov/feature/goddard/2017/chasing-the-total-solar-eclipse-from-nasa-s-wb-57f-jets
