President Donald Trump directed the formation of a new military branch dedicated to fighting in outer space, called Space Force, that would be separate but equal to the the US Air Force during a meeting of his National Space Council.

As part of ESA’s Expose-R2 project, 46 species of bacteria, fungi and arthropods were delivered by a Progress supply ship to the International Space Station in July 2014. Spacewalking cosmonauts Alexander Skvortsov and Oleg Artemyev attached the package to the outside of the Zvezda module on 18 August 2014, where it stayed until it was retrieved 18 months later. This ‘Expose-R2’ is a miniature photochemistry laboratory that exposes samples to the harsh environment of space. Subjected to the full blast of the Sun’s energy as well as vacuum, radiation and temperature swings, they are helping researchers investigating how chemicals and microbiological life react to unprotected spaceflight – on a comet, for example. Previous Expose experiments have already shown that ‘water bears’ and a species of lichen can survive a trip into space. This video shows scenes from a spacewalk with cosmonauts Gennadi Padalka and Mikhail Kornienko who were asked to photograph the Expose-R2 facility half-way through its stay in space, 10 August 2015 – the samples had travelled around the world more than 8500 times by then. Expose-R2 was returned inside the International Space Station Station by Yuri Malenchenko and Sergei Volkov during a spacewalk on 3 February 2016 and stored ahead of return to Earth. The samples were held in sealed compartments and covered to block out all light. The vacuum of space is sucking out the water, oxygen and other gases in the samples. Their temperature can drop to –12°C as the Station passes through Earth’s shadow, rising to 40°C at other times, and undergoing a similar process to the freeze-drying used to preserve foods. The Expose series of experiments are exploring the limits of terrestrial life, whether the organisms can survive in space and how the full blast of solar radiation is affecting accompanying chemicals. Earth is protected from the Sun’s full radiation by our atmosphere filtering out the hard-hitting short wavelengths that are damaging to life. It is difficult to recreate on the ground the full spectrum of the Sun’s light so these experiments in space are the only way to test how biological and material samples behave in conditions beyond Earth. ESA has a long history of testing organisms and organic chemicals in the harsh environment of space. Previous experiments revealed that lichens and water bears can survive spaceflight unprotected, hinting at the possibility of species colonising planets via meteoroids. ★ Subscribe: http://bit.ly/ESAsubscribe

Triton is a moon of Neptune and it is also one of the most interesting moons in the Solar System. In this video i take a look at Triton Hopper, which is a lander that will also hop on the surface and fly, that is if it ever gets the chance to.

Editor's note: The ICESat-2 launch date is Sept. 12, not Sept. 2. This week in space news, a SpaceX Dragon cargo spacecraft will resupply the International Space Station with a launch from Cape Canaveral Air Force Station in Florida later this month. NASA's Ice, Cloud, and land Elevation Satellite-2, or ICESat-2, arrived at Vandenberg Air Force Base in California on Tuesday.

Last week, NASA released some pretty cool Mars news: Curiosity found even more evidence to indicate the planet could’ve been habitable billions of years ago.

The first video shows an active region on the Sun (with an inset Earth, for size reference) taken in extreme ultraviolet, or EUV, light by the Solar Dynamics Observatory. The EVE sounding rocket supports the calibration of EUV measurements taken by spacecraft to make sure the data they provide are accurate. With the usual focus on satellite-based solar imagery, one often forgets about the important contributions of ground-based observatories. Here we present a video of imagery collected at the Big Bear Solar Observatory (BBSO) site of the National Solar Observatory (NSO). The light from the Sun is passed through a filter that admits light from the hydrogen alpha spectral line (6562.8 angstroms or 656.28 nanometers) in the red region of the spectrum. This reveals many details which cannot be seen in our usual broad-spectrum view of the Sun, particularly filaments across the solar disk and limb. Ground-based observatories are subjected to a number of challenges different from their space-based counterparts, including gaps in the visibility of their target (i.e. nighttime), clouds (some slightly visible in this movie) and atmospheric turbulence (also some visible here). The spectral line for hydrogen alpha is a deep red and rather dark for regular digital displays. For this visualization, we have used a brighter 'blackbody' colour table to improve visibility.

Today we take a trip inward, to explore Sun-Scorched Mercury. Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ Mercury is the nearest planet to the Sun, a seeming airless wasteland little discussed in conversations about colonizing our solar system. Today we will challenge that, and show that Mercury may be one of the most promising places for humanity to make new homes on.

Very few videos or tutorials around on Flocking (reducing the internal reflections of the tube by fitting black non-reflecting material). Here is my (successful) attempt, but with the first faltering steps left in, as I learn't more from the mistakes than getting it right first time! My longest video, at just over 18 mins!

Join +Fraser Cain and +Pamela Gay for a live episode of Astronomy Cast. We'll record our 30-minute show, and then stay tuned for them to answer questions! Our knowledge of space is starting to match up with our ability to get out there an explore it. There are several companies working on missions and techniques to harvest minerals from asteroids. What other resources are out there that we can use?
