Washington, D.C. – After 10-month voyage across more than 400 million miles of empty space, NASA’s MAVEN spacecraft reached Mars on September 21st 2014. Less than 8 hours later, the data started to flow.
“Our Imaging Ultraviolet Spectrograph (IUVS) obtained these false-color images of Mars on September 22nd,” says Nick Schneider who leads the instrument team at the University of Colorado. “They trace the distribution of hydrogen and oxygen in the Martian atmosphere.”
Washington, D.C. – If an asteroid big enough to knock modern civilization back to the 18th century appeared out of deep space and buzzed the Earth-Moon system, the near-miss would be instant worldwide headline news.
Two years ago, Earth experienced a close shave just as perilous, but most newspapers didn’t mention it. The “impactor” was an extreme solar storm, the most powerful in as much as 150+ years.
“If it had hit, we would still be picking up the pieces,” says Daniel Baker of the University of Colorado.
Washington, D.C. – Years ago, in 2008 and 2009 an eerie quiet descended on the sun. Sunspot counts dropped to historically-low levels and solar flares ceased altogether. As the longest and deepest solar minimum in a century unfolded, bored solar physicists wondered when “Solar Max” would ever return.
They can stop wondering. “It’s back,” says Dean Pesnell of the Goddard Space Flight Center. “Solar Max has arrived.”
Washington, D.C. – Last month (April 8th-11th), scientists, government officials, emergency planners and others converged on Boulder, Colorado, for NOAA’s Space Weather Workshop—an annual gathering to discuss the perils and probabilities of solar storms.
The current solar cycle is weaker than usual, so you might expect a correspondingly low-key meeting. On the contrary, the halls and meeting rooms were abuzz with excitement about an intense solar storm that narrowly missed Earth.
