NPR's Robert Siegel talks to Fran Bagenal, a member of the science team on NASA's historic Juno mission to Jupiter.
"It's a milestone for planetary science," says a leader of the mission to put a spacecraft into orbit around the large planet whose radiation and dust particles pose dangerous challenges.
NASA's probe to Jupiter must fire its main engine to be captured by the giant planet's gravity. If the rocket doesn't fire, it's mission over. NPR's Ari Shapiro speaks with science correspondent Joe Palca from Pasadena.
"It's getting very real," says a leader of the mission to put a spacecraft into orbit around the large planet whose radiation and dust particles pose dangerous challenges.
Space navigation is tricky. There's no up or down, no left or right, and no road signs. This device uses stars to help determine if a spacecraft is off course. It takes nifty pictures, too.
The craft is designed to glean data from Jupiter that could also help us learn how Earth formed. But first, Juno has to get into orbit — determined by a crucial half-hour of firing by its main engine.
Scientists are worried about how Britain's departure from the European Union would hurt the continent's mega-projects and its researchers. Scientific collaboration "should know no borders," says one.
Scientists say that in a Swedish quarry, they've uncovered a meteorite unique among the 50,000 known on Earth today. They say it could hold clues about the history of the solar system.
For the second time in recent months, scientists say they have picked up distortions in space and time. The find suggests smaller-sized black holes may be more numerous than many scientists thought.
