Explainer: the International Space Station

As the most visible man-made object in the night sky the International Space Station (ISS) is of significance to humankind. It takes humans from being explorers of space to being residents of space. The…

Buy, sell, lift-off: the global economy is going interplanetary

Harvesting space resources will raise living standards worldwide, without further damaging Earth. So how can those resources be tapped in a way that will produce a return on investment? That question may…

Looking for planets just like Earth

University of Auckland scientists have proposed a new way to find planets like Earth. The research strategy includes the…
The Alpha Magnetic Spectrometer has produced results consistent with the presence of dark matter. NASA

New light on dark matter: space station magnet attracts praise

Nobel prizewinner Samuel Ting, early this morning (AEDT), announced the first results from the Alpha Magnetic Spectrometer (AMS) search for dark matter. The findings, published in Physical Review Letters…

Satellite of love: our on-off relationship with the moon

Like all relationships, our association with the moon has had its ups and downs. In this series we’ve talked about the nature of the satellite and how we think it was formed - in a giant collision that…
What do we know about how the moon was created? EPA/Ali Ali

Crash – a-ah! Our moon has a history of violence

The more we learn about the formation and evolution of our solar system, the more we realise it was far from a sedate, gentle process. Everywhere we look we find evidence the final stages of planetary…

I see the moon: introducing our nearest neighbour

The moon. Our nearest neighbour. The main source of the ocean’s tides, and a beacon that drives the lives of animals across the globe. And also, to date, the only object beyond Earth on which humans have…
Observations from NASA’s Van Allen Probes have revealed that a third radiation belt can sometimes appear above Earth. NASA/Goddard Space Flight Center

NASA discovers a new radiation belt around Earth

NASA revealed this morning (AEST) that its Van Allen Probes have discovered a third, previously unknown, radiation belt around Earth. The belt appears to be transient, depending strongly on solar activity…
The reflected light from black holes enables astronomers to see how fast matter is swirling in the inner region of the disk, and ultimately to measure the black hole’s spin rate. NASA/JPL-Caltech

NASA puts new spin on black holes

Scientists in the US have successfully used a new NASA telescope to help improve our understanding of how black holes and galaxies evolve. Using data taken by the Nuclear Spectroscopic Telescope Array…
NASA’s RASSOR will be able to climb hills and, more importantly, extract water, ice and fuel from lunar soil. NASA

Space robots – coming soon to a planet near you

Earlier this week, NASA announced the development of a mining robot called RASSOR: the Regolith Advanced Surface Systems Operations Robot. RASSOR has been designed to assist in extracting water, ice and…
The red planet’s McLaughlin Crater may have contained water sourced from within the ground. NASA

Hope springs: signs of life could be waiting for us on Mars

A recent article in Nature Geoscience suggests that at least one large, deep crater on Mars may once have supported an alkaline lake that was fed by water from kilometres below the planet’s surface. This…
This still image and animation shows the final flight path for NASA’s twin Gravity Recovery and Interior Laboratory (GRAIL) mission spacecraft, which impacted the moon on Dec. 17, 2012, around 2:28 p.m. PST. Their successful prime and extended science missions now completed, the twin GRAIL spacecraft Ebb and Flow are being sent purposefully into the moon because their low orbit and fuel state precludes further scientific operations. The animations were created from data obtained by NASA’s Lunar Reconnaissance Orbiter. NASA/JPL-Caltech/GSFC/ASU

NASA crashes space junk into the moon to save lunar heritage sites

NASA deliberately crashed two decommissioned space craft into the moon today in a controlled landing aimed at preserving heritage sites on the lunar surface. The twin space ships, named Ebb and Flow, were…

NASA’s Curiosity shows there’s more to life than life

The Curiosity rover has landed on Mars, driven around, started its scientific mission and, as of 4am today (AEDT), started reporting integrated science results. In a news conference at the American Geophysical…
It’s not everyday you get to chat with a spacecraft that’s nearing the edge of the solar system. NASA

An interview with Voyager 2 … at the edge of the solar system

Interviewing a spacecraft isn’t something one does every day. It certainly wasn’t an option back in the late 1970s, when Voyager 1 and 2 set off on a mission like no other before or since: to visit some…
NASA’s latest rover has touched down successfully on the red planet. NASA/JPL

NASA’s Curiosity is on Mars safely – so now what?

At 3.31pm today (AEST) the NASA control room in Pasadena, California erupted after people heard these three simple words: “touchdown signal detected”. This diminutive sentence signalled that the Curiosity…

Curiosity rover has landed on Mars … let the science begin

The Mars Science Laboratory, otherwise known as the Curiosity rover, has safely landed on the red planet. While NASA engineers can now breath a sigh of relief, for a small army of people, the work on Mars…
