In case you missed it here is an interview with Tim Peake’s the day after his return to Earth.
Noctilucent clouds are beautiful and strange at the same time. You can indeed see them from the ground and are a welcome site.
This image was taken on 29 May 2016 by Tim Peake aboard the ISS:
The NASA Image of the Day caption:
Expedition 47 Flight Engineer Tim Peake of the European Space Agency photographed rare, high-altitude noctilucent or “night shining” clouds from the International Space Station on May 29, 2016.
Polar mesospheric clouds — also known as noctilucent clouds – form between 76 to 85 kilometers (47 to 53 miles) above the Earth’s surface, near the boundary of the mesosphere and thermosphere, a region known as the mesopause. At these altitudes, water vapor can freeze into clouds of ice crystals. When the sun is below the horizon and the ground is in darkness, these high clouds may still be illuminated, lending them their ethereal, “night shining” qualities.
In the late spring and summer, unusual clouds form high in the atmosphere above the polar regions of the world. As the lower atmosphere warms, the upper atmosphere gets cooler, and ice crystals form on meteor dust and other particles high in the sky. The result is noctilucent or “night-shining” clouds — electric blue wisps that grow on the edge of space. Polar mesospheric clouds can be observed from both the Earth’s surface and in orbit by astronauts aboard the International Space Station.

This is a remarkable image! I have tried on numerous occasions to get an image of the International Space Station as it passes over the disk of the Sun, something always goes wrong. It is a VERY difficult endeavor with so many variables.
Then there is a master at the craft of astrophotography: Thierry Legault. Not only did he capture the ISS, he did it during the transit of Mercury!
This from ESA (be sure to watch the video linked below):
On 9 May Mercury passed in front of the Sun as seen from Earth. These transits of Mercury occur only around 13 times every century, so astronomers all over Earth were eager to capture the event.
For astrophotographer Thierry Legault, capturing Mercury and the Sun alone was not enough, however – he wanted the International Space Station in the frame as well.
To catch the Station passing across the Sun, you need to set up your equipment within a ground track less than 3 km wide. For Thierry, this meant flying to the USA from his home near Paris, France.
On 9 May there were three possible areas to capture the Station and Mercury at the same time against the solar disc: Quebec, Canada, the Great Lakes and Florida, USA.
Choosing the right spot took considerable effort, says Thierry: “Canada had bad weather predicted and around Florida I couldn’t find a suitably quiet but public place, so I went to the suburbs of Philadelphia.”
With 45 kg of equipment, Thierry flew to New York and drove two hours to Philadelphia to scout the best spot. Even then, all the preparations and intercontinental travel could have been for nothing because the Station crosses the Sun in less than a second and any clouds could have ruined the shot.
“I was very lucky: 10 minutes after I took the photos, clouds covered the sky,” says a relieved Thierry.
“Adrenaline flows in the moments before the Station flies by – it is a one-shot chance. I cannot ask the space agencies to turn around so I can try again. Anything can happen.”
The hard work and luck paid off. The image here includes frames superimposed on each other to show the Station’s path. Mercury appears as a black dot at bottom-centre of the Sun.
For Thierry, the preparation and the hunt for the perfect shot is the best part.
“Astrophotography is my hobby that I spend many hours on, but even without a camera I encourage everybody to look up at the night sky. The International Space Station can be seen quite often and there are many more things to see. It is just a case of looking up at the right time.”

The Bigelow Expandable Activity Module or BEAM was inflated this week. The very first human-rated space structure of its kind!
Tim Peake on the accomplishments of the ISS after completing 100,000 orbits of the Earth. He summed it up nicely.
Congratulations to the International Space Station on completing 100,000 orbits since the station was launched on 20 Nov 1998. In the years since launch the station will have traveled around 2,643,342,240 miles, or roughly the distance between Earth and Neptune.
The event occurred at 06:10 UTC this morning 16 May 2016.
Iconic Liquids are a special class of liquids that are also environmentally friendly.
Tim Peake takes control of the ESA’s Mars rover prototype named Bridget located in the UK from the International Space Station.
He controlled the rover for two hours and even drove it into a simulated cave. Nice work!
I don’t know what the odds of the rover going into a cave on Mars but I would hope they would code in a reverse route in the event radio contact was lost.
Here’s a look at BEAM (Bigelow Expandable Activity Module) installed on the ISS.
The module is not expanded yet, that is scheduled for late-May. This is a two-year evaluation to see how these types of habitat will work out over time.
