Here's what 6 billion kilometers away from Earth looks like
|
view preview
At roughly 6 billion kilometers from Earth, the image you see to your right is the farthest images ever taken. The New Horizons spacecraft captured its first images on August 16 of the remote icy world nicknamed Ultima Thule (a traditional name of distant places beyond the known world), confirming that New Horizons is on track for its January 1 flyby around Pluto. With about 160 million kilometers to go — roughly the same distance as Earth is from the sun — the tiny world appears as no more than a faint speck in the probe’s camera. Officially named 2014 MU69, Ultima Thule is part of the Kuiper Belt, a thick disk-shaped zone containing space debris left over from the formation of the planets 4.6 billion years ago. By sending New Horizons to t ...

A closer look at Saturn's moon
|
view preview
NASA’s Cassini spacecraft completed the first of three final flybys of Saturn’s icy moon, Enceladus. On October 14, Cassini passed within 1838 kilometers (1142 miles) of Enceladus, providing unprecedented views of the moon’s north polar region. What's more, researchers predict that is contains a global ocean lying beneath its icy crust. Researchers found the magnitude of the moon's very slight wobble, as it orbits Saturn, can only be accounted for if its outer ice shell is not frozen solid to its interior, meaning a global ocean must be present. ...

Definitive proof of water found on Mars
|
view preview
Since its discovery in 2010, researchers have been trying to solve the mystery of dark streaks that appear and disappear seasonally on the planet's surface (shown above). Scientists are now claiming that this phenomenon, known as the recurring slope lineae, is caused by a bath of saltwater. What is still unknown, however, is where the water is coming from, or if the chemistry is even right for supporting life.

This man was paid $18 000 by NASA to lie on his back for 70 days straight
|
view preview
The study, titled "CFT 70 ( Countermeasure and Functional Testing in Head-Down Tilt Bed Rest Study)," aimed to learn more about how human bone and muscle might deteriorate in space. According to Drew Iwanicki, who took part in the study and who is pictured above, he experienced some serious headaches because of increased blood pressure to his head. His spine went through some serious pain, and staying horizontal was difficult. However, as soon as the bed was tilted to the vertical position, after 70 days of course, his legs felt heavier and his heart started to beat at 150 BPMs. ...

NASA Spacecraft is 4 weeks and 32 million km away from Pluto
|
view preview
After a journey spanning nine years and almost 5 billion kilometres, NASA’s New Horizons spacecraft is closer than ever to everyone’s favourite former planet, Pluto. On 14 July 2015, New Horizons is expected to fly within 12,000 km of the lonely cosmic body - about the distance between Seattle and Sydney - zooming through the orbits of its five tiny moons.

Rosetta's Comet - Update
|
view preview
Remember Philae? That little lander that was targeting comet Rosetta? https://biology-forums.com/index.php?article=1050It was very big news around two months ago... Sadly, Philae landed incorrectly in a rather awkward position due to technical failings. After all, it was trying to land on the harsh, unstable, deteriorating/burning up surface of a comet. It bounced three times to a site away from the targeted position and ended up in a shady place with insufficient sunlight to recharge its energy reserves. And so it died out after 60 hours of touchdown. Recent tabloids have now reported that Philae is missing! Scientists from the European Space Agency have tried to analyze the images that Philae returned but things just keep on getting more ...

Aurora borealis
|
view preview
This picture of a green and red aurora was taken on September 26, 2013, from the International Space Station. The colours of the aurora borealis depend on which atoms the solar storm excites. Green auroras appear when charged particles from the solar wind crash with oxygen atoms in Earth’s atmosphere and produce green photons; red auroras occur when the particles collide with nitrogen atoms or when there are lower-energy oxygen collisions, producing red photons.

Capturing an asteroid
|
view preview
According to scientists at The Keck Institute for Space Studies in California, NASA is seriously considering capturing an asteroid to put in a high orbit around the moon. If the idea is implemented, we could be looking at a manned mission to "capture" an asteroid in the 2020s. This idea is thought to tie in with the Obama administration's enthusiasm for sending a manned mission to a near-Earth asteroid. If NASA were able to capture an object and lock it into an orbit around the moon, it could be safely used as a practise mission without the need for astronauts to move beyond the range of a rescue mission. ...
