A large asteroid thought to be the metallic core of a destroyed proto-planet appears to have molecules on its surface that shouldn't be there, according to a new study.
Research led by UA professor Renu Malhotra provides additional support for the possible existence of such a world and narrows the range of its parameters and location.
UA professor Bill Boynton has contributed to 10 NASA missions in his lifetime, including OSIRIS-REx, which began its journey to the asteroid Bennu last month. But this month, Boynton can’t help but think about Mars and the Odyssey mission, celebrating its 15th anniversary.
The "proud parents" of the UA's mission team talk about their excitement after a flawless launch sequence, their jitters prior to powering up the spacecraft's instruments for the first time in space, and what it takes to talk to a robotic probe hurtling around the sun millions of miles away.
The conference is the largest international civil-military conference dedicated to space surveillance. The UA's prominence reinforces its lead in the emerging space surveillance industry.
The Atlas V that carried the OSIRIS-REx spacecraft off the planet was one big birthday candle for the mission's deputy principal investigator, who is retiring from the UA and heading off to do some backpacking. With a must-see UANews video of highlights from last week's launch in Florida.
After 12 years, the spacecraft for the OSIRIS-REx asteroid sample return mission is finally off the ground, much to the relief of the scientist who has been there every step of the way, Dante Lauretta.
The UA-led OSIRIS-REx mission, conceived 12 years ago and finally green-lighted by NASA in 2011, is the first U.S. mission to send a robotic spacecraft to retrieve a sample from a primitive carbonaceous asteroid.
Meet UA alumna Daniella DellaGiustina, the lead image processing scientist for the OSIRIS-REx asteroid sample return mission. DellaGiustina wasn't planning on a career in planetary science but has become one of several key women on the project.
The countdown is on for Thursday, and the community is invited to the UA Mall to watch the launch of the first U.S. mission to bring back a sample from an asteroid. In addition, businesses near campus and in downtown Tucson will host events and promotions to celebrate the UA-led mission.
