What's up in planetary missions in 2014

Posted by Emily Lakdawalla on 2013/12/31 01:15 CST | 4 comments

With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa 2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.

Conversations with an interplanetary spacecraft: "Hi, Juno!"

Posted by Emily Lakdawalla on 2013/12/17 09:37 CST | 6 comments

Juno's Earth flyby represented the first opportunity for many of the science instruments to be used on a planetary target. There were terrific photos of Earth and the Moon, plus a cool project to see if Juno could detect intelligent life on Earth.

Juno is in Safe Mode again, but still okay
All Earth flyby data on the ground, including JunoCam images

Posted by Emily Lakdawalla on 2013/10/16 06:59 CDT | 6 comments

After entering safe mode last week during its Earth flyby, Juno returned to normal operations and downlinked all engineering and science instrument data. It entered safe mode again on Sunday night, but it is expected to re-resume normal operations late next week.

Juno is in safe mode, but okay and on course following Earth flyby

Posted by Emily Lakdawalla on 2013/10/09 05:56 CDT | 5 comments

Following its Earth flyby earlier today, Juno is in safe mode. This is the protective state a spacecraft goes into when it detects a problem. But everything is okay. For more details, I just spoke with Rick Nybakken, Juno Project Manager at the Jet Propulsion Laboratory.

Junocam will get us great global shots down onto Jupiter's poles

Posted by Emily Lakdawalla on 2011/08/05 03:31 CDT | 1 comment

Juno is a mission that will peer deeply into Jupiter's interior, and didn't really need to take a visible-light camera along in order to accomplish its scientific goals. But I think nobody could bear sending a spacecraft to Jupiter without getting pictures from up close. So they added Junocam.

Juno is being shipped to Cape Canaveral today

Posted by Emily Lakdawalla on 2011/04/08 11:15 CDT

Spaceflight Now is following along as the next Jupiter orbiter, Juno, is journeying from its birthplace at Lockheed Martin in Denver to Cape Canaveral. As of this moment it has been packed up and loaded onto a flatbed trailer, which is driving through Denver with police escort, en route to the Denver airport, where it'll board a C-17 for the trip to Florida.
