Space treaties are a challenge to launching small satellites in orbit
Until recently the idea of launching a satellite into space was an expensive business and the preserve of governments, international space organisations and multi-million dollar companies.
NASA spacecraft achieves unprecedented success studying Mercury
After extraordinary science findings and technological innovations, a NASA spacecraft launched in 2004 to study Mercury will impact the planet's surface, most likely on April 30, after it runs out of propellant.
GOCE gravity satellite produces maps for geothermal energy development
Going far above and beyond its original mission objectives, results from the GOCE gravity satellite are now being used to produce maps for geothermal energy development.
Earth ate a Mercury-like body early in its history, study finds
A Mercury-like body smashed into a young Earth and gave our planet's core the radioactive elements necessary to generate a magnetic field, two Oxford geochemists say.
Accurately counting ions from laboratory radiation exposure
Thermoluminescence is used extensively in archaeology and the earth sciences to date artifacts and rocks. When exposed to radiation, quartz emits light proportional to the energy it absorbs. Replicating the very low dose ...
Irradiating formamide with meteorite dust can lead to synthesis of prebiotic compounds
Snowball Earth: New study shows Antarctic climate even gripped the tropics
New details of a nightmare period on Earth with surface conditions as frigid as present-day central Antarctica at the equator have been revealed thanks to the publication of a study of ancient glacier water.
Meteorites key to the story of Earth's layers
A new analysis of the chemical make-up of meteorites has helped scientists work out when the Earth formed its layers.
Will asteroid 2012 TC4 hit Earth in October 2017?
On Oct. 12, 2017, the asteroid 2012 TC4 is slated to whizz by Earth dangerously close. The exact distance of its closest approach is uncertain, as well as its size. Based on observations in October 2012 when ...
Cosmic debris: Study looks inside the universe's most powerful explosions
A new study provides an inside look at the most powerful explosions in the universe: gamma-ray bursts.
The origin of the Moon and its composition
The Moon is thought to have formed from the debris of a small planet that collided with the Earth. Since the composition of other planets in the solar system differs from that of the Earth, it was expected ...
Synthetic muscle ready for launch to Space Station
Lenore Rasmussen's dream of developing a synthetic muscle that could be used to make better prosthetic limbs and more responsive robots will literally become airborne on April 13 at 4:33 p.m. when her experiment ...
System to rate the scarcity of important metals aims to keep shortage at bay
Store cupboards usually contain the basics – canned tomatoes, soup, dry goods – but rarely the more exotic additions required in small amounts to make a dish sing. In the same way, a growing shortage ...
Final solar wing deployment test for Sentinel-2A
Once in space, Sentinel-2A will open its solar wing to generate the power it needs to carry out the task of monitoring Earth's vegetation. Engineers have recently made sure this move is well rehearsed before ...
