As plans for space exploration expand, how will sex and desire be addressed in these larger, longer missions?
Sex technologies and 'erobots' could help address issues related to human desire, and physical and emotional needs of astronauts in space.
The Hawaii Space Exploration Analog and Simulation (HI-SEAS) is a research facility designed to simulate conditions on Mars.
In preparation for possible future missions to Mars, scientists figure out how to quickly and efficiently measure brain performance and mental fatigue.

An expert explains the challenges of a mission to Mars for younger readers.
SpaceX’s Dragon 2 will carry humans for the first time in 2020.
From alien life to human spaceflight, 2020 may deliver some exciting news.
In 2015, NASA’s New Horizons spacecraft looked back toward the sun and captured this near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto’s horizon.
Many people are still upset that Pluto was demoted from being a planet. But definitions of various celestial objects are fairly fluid. So whether it is an asteroid or moon or planet is up for debate.

Collecting samples from Mars and brining them back to Earth will be a hugely complicated task, but it may be our best bet of finding alien life.

New research on landslides on Mars could help protect against devastating landslides on Earth.
The red planet. It may hold no life, but is it dead?
NASA has released a sound recording from Mars. So what do these literally otherworldly sounds tell us about the processes at play inside the red planet?

From solar sail-powered spacecraft, to laser communications, to asteroid detection systems, there is no shortage of Australian ideas and expertise to help NASA explore the Moon and Mars.
Much of Mars’s surface is covered by fine-grained materials that hide the bedrock. The above bedrock is mostly exposed and it is in these areas that micrometeorites likely to accumulate.

It's established Mars was once a planet with surface-level water. So with multiple MARS missions starting next year, the key to seeking out martian life may instead lie in the contents of its 'dust'.
On June 5-6, 2012, NASA’s Solar Dynamics Observatory collected images of one of the rarest predictable solar events: the transit of Venus across the face of the Sun.
This hot, acidic neighbor with its surface veiled in thick clouds hasn't benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.
