The first spacecraft is the Trace Gas Orbiter, which ESA will build and NASA will launch.
Today, both space agencies issued an Announcement of Opportunity inviting scientists to propose instruments to be carried on the mission. Once all proposals are in, they will be evaluated and the winning teams will be tasked with building the actual hardware.
A Joint Instrument Definition Team has identified a model payload based on current technology, but turning that blueprint into reality is now the job of the scientific community. “We are open to all instrumental proposals so long as they help us achieve our scientific objectives,” says Jorge Vago, ESA ExoMars Project Scientist.
The priority for this mission is to map trace gases in the atmosphere of Mars, distinguishing individual chemical species down to concentrations of just a few parts per billion. Of these gases, one in particular attracts special attention: methane. Discovered on Mars in 2003, it happens to be a possible ‘biomarker’, a gas that is readily produced by biological activity. Understanding whether the methane comes from life or from geological and volcanic processes takes precedence. “The methane is the anchor point around which the science is to be constructed,” says Vago.
Adding to the mystery is that methane was found to be concentrated in just three locations on Mars, and then disappeared much faster from the atmosphere than scientists were expecting. This points to an unknown destruction mechanism much more powerful than any known on Earth. It may also indicate a much faster creation process to have produced such large quantities of the gas in the first place.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
