SciTech Daily 24 Jun 2019, 02:06 UTC Good fortune and cutting-edge scientific equipment have allowed scientists to observe a Gamma Ray Burst jet with a radio telescope and detect the polarisation of radio waves within it for the first time – moving us closer to an understanding of what causes the universe’s most powerful explosions.
Deep Space Atomic Clocks Will Help Spacecraft Answer, with Incredible Precision, if They’re There Yet21 Jun 2019, 17:29 UTC How do spacecraft know where they are? There’s no GPS out there. Right now, it involves sending a signal to the spacecraft which the spacecraft then sends right back to Earth. The elapsed time reveals the distance. But on June 24th, that method could be replaced by something much more autonomous.

The Guardian 20 Jun 2019, 23:01 UTC For thousands of years people have made the pilgrimage to Stonehenge to gaze in wonder at the interplay with the monument of the sun, moon and stars, but from Friday a virtual version of the looming sky above the circle will be available to people from around the world.
Centauri Dreams 20 Jun 2019, 16:37 UTC Ever since the passage of interstellar interloper ‘Oumuamua, we’ve become aware of the opportunities presented by objects entering our system from interstellar space, at the same time wishing we had the resources at hand to investigate them close-up. Andreas Hein and colleagues at the Initiative for Interstellar Studies have examined the possibilities for reaching ‘Oumuamua through Project Lyra (see Project Lyra: Sending a Spacecraft to 1I/’Oumuamua), a study that also takes in the kind of future infrastructure that could allow us to react to the next such object. Now comes the interesting news that the European Space Agency is developing a mission called Comet Interceptor, one capable of visiting a long-period comet coming into the inner system from the Oort Cloud, but just as capable of reaching an interstellar visitor. The idea revolves around not a single spacecraft, but a combination of three. The composite vehicle would be capable of orbiting the L2 Lagrange point 1.5 million kilometers from Earth until it finds a suitable target. At that point, it would journey to the object and separate into three modules.
New Scientist 20 Jun 2019, 11:59 UTC Mars’s twin moons may soon get a visitor. We’ve never landed anything on Phobos and Deimos, but we have taken pictures of their surfaces from orbiters around Mars. Now, a mission headed by JAXA, the Japanese space agency, is set to launch a rover to one of these small moons in 2024 – the final destination is yet to be decided.
