Down To Earth

Some new videos from Blue Origin and SpaceX of their recent rocket successes were released this past week:

The astronaut Kelly brothers, Mark and Scott, had their childhood elementary school named after them this past week.

Two astronauts, Scott Parazynski and Brian Duffy, were inducted into the astronaut hall of fame.

The amazing Thierry Legault has done it again, this time taking a video of the ISS transiting the sun at the same time as the Mercury transit on May 9th.

An unusual parade happened in Los Angeles on May 21st when the last Space Shuttle External Tank was towed from the coast to the California Science Center.

In Orbit

The Indian Space Research Organization launched their new experimental space plane on May 23rd. The uncrewed vehicle actually didn’t make it to orbit, or even to space, reaching only a peak altitude of 65 km. Still, reaching Mach 5 on re-entry is no joke.

The only other notable rocket launch since my last post on May 9th was a Chinese low earth orbit (LEO) reconnaissance satellite launched on May 15.

Around the Solar System

Some recent experiments in a Martian atmosphere simulator have given us an update on the Recurring Slope Linae (RSL), which were announced last year as evidence of flowing liquid water on Mars. It may be that ice boiling directly to a gas may be causing the features.

NASA’s flying telescope, SOFIA, has detected atomic oxygen in the atmosphere of Mars. Atomic oxygen is highly reactive and thus can tell us a lot about what is going on at Mars, potentially even the chance for life.

Speaking of Mars, check out this new image from Hubble. Mars is at opposition this week – or the closest approach to Earth – making it a great target for Earth-based astronomers.

Out There

You probably didn’t miss this story: NASA announced the confirmation of more than 1,200 new exoplanets discovered by the Kepler Space Telescope. This brings the total planets discovered outside our solar system to over 3,300 worlds.

    Enjoy summaries like this to make sure something didn’t slide by. How I didn’t know Humans To Mars Summit 2016 wasn’t happening, I…. I don’t even know.
