NASA has selected the University of Arizona to lead one of its four inaugural Astrophysics Pioneers missions. With a $20 million cost cap, the Aspera mission will study galaxy evolution with a space telescope barely larger than a mini fridge. The telescope will allow researchers to observe galaxy processes that have remained hidden from view until now.

SAN FRANCISCO – NOAA’s National Satellite, Data and Information Service is recommending flying three satellites over the United States in the satellite constellation that will follow the Geostationary Operational Environmental Satellite R Series (GOES-R).

In addition, to operating satellites in orbits similar to those of the current GOES East and GOES West satellites, NOAA recommends placing a third spacecraft over the center of the United States, Pam Sullivan, GOES-R system program director, said Jan.

Researchers find Mars has a Chandler wobble

A combined team of researchers from the Jet Propulsion Laboratory, California Institute of Technology and the Royal Observatory of Belgium, has found evidence that Mars has a Chandler wobble. In their paper published in the journal Geophysical Research Letters, the group describes their study of decades of data from Mars probes and what it showed them.

Approximately a century ago, astronomer Seth Carlo Chandler discovered that imperfectly round objects (such as planets) sometimes spin off their axis for periods of time. The phenomenon has come to be known as the Chandler wobble, and has been documented for planet Earth, which veers from its axis for distances up to 30 feet in a pattern that repeats approximately every 433 days. Researchers have suggested that other planets likely have a Chandler wobble, but until now, it has never been observed because measuring it on the planet scale requires over many years. In this new effort, the researchers obtained the right kind of data from that orbited Mars over many years: The Mars Reconnaissance Orbiter, the Mars Global Surveyor and Mars Odyssey.

Coronal holes during the solar maximum
An ultraviolet image of the Sun showing a coronal hole - a dark region, seen here at the north pole of the Sun with NASA’s Solar Dynamics Observatory. Coronal holes are regions where the weakened magnetic field allows for a stronger solar wind to emerge. Astronomers have found correlations between coronal holes near the Sun's equator and the eleven and twenty-two year solar cycles.

This little black camera looks like something out of a spy movie - the kind of device one might use to snap discrete photos of confidential documents. It's about half the size of a computer mouse. But the only spying this camera - four of them, actually - will do is for NASA researchers wondering what happens under a spacecraft as it lands on the Moon. It's a tiny technology wi

NASA has chosen four small-scale astrophysics missions for further concept development in a new program called Pioneers. Through small satellites and scientific balloons, these selections enable new platforms for exploring cosmic phenomena such as galaxy evolution, exoplanets, high-energy neutrinos, and neutron star mergers. "The principal investigators of these concept studies bring innov
