It’s the Beginning of the End for Cassini (But the Pictures Will Be Awesome)

After more than twelve years in orbit around Saturn, NASA’s Cassini spacecraft is now in its final year of operation…and newly-positioned in an orbit that will send it soaring high over the planet’s north pole as well as close by the outer edge of its glorious shining rings.

Over the course of 20 week-long “ring-grazing orbits” — the first of which was completed on Dec. 4 — Cassini will obtain close-up images and data on the composition and structure of Saturn’s rings and nearby shepherd moons.

It’s the mission’s penultimate phase, heralding the end of Cassini in September 2017.

“This is it, the beginning of the end of our historic exploration of Saturn,” said Cassini imaging team leader Carolyn Porco. “Let these images — and those to come — remind you that we’ve lived a bold and daring adventure around the solar system’s most magnificent planet.”

More Moons For Uranus?

The distant ice giant Uranus may not have been visited by a spacecraft since Voyager 2’s “Grand Tour” flyby in 1986 but the data gathered then is still being used today to make new discoveries. Most recently, researchers think they have found evidence of two previously unknown moons around Uranus, potentially bringing the planet’s count up to 29.

With One More Comet Landing Rosetta’s “Rock and Roll” Mission is Ended

Rosetta is down. I repeat: Rosetta is down.

This morning, Sept. 30, 2016, just after 10:39 UTC (6:39 a.m. EDT) ESA’s Rosetta spacecraft ended its mission with an impact onto the surface of the comet 67P/Churyumov-Gerasimenko. The descent, begun with a final burn of its thrusters about 14 hours earlier, was slow, stately, and deliberate, but even at a relative walking pace Rosetta was not designed to be a lander like its partner Philae and thus ceased operation upon contact with the comet.

With the comet 446 million miles (719 million km) from Earth at the time, the final signals from Rosetta were received 40 minutes after impact, officially confirming mission end.

NASA is about to embark on its first mission to sample an asteroid—and I’ll have a front-row seat to the launch!

On Thursday, Sept. 8, at 7:05 p.m. (23:05 UTC) the launch window opens for the launch of OSIRIS-REx, NASA’s mission to visit the near-Earth asteroid Bennu, orbit and map it, collect a sample and return it to Earth. The 8-foot-wide, 20-foot-long spacecraft will launch aboard a ULA Atlas V rocket from Cape Canaveral AFS and as a member of the latest NASA Social event I and 99 other attendees will be at the Cape to see it off on its 7-year journey. Be sure to follow me on Twitter and Instagram to see pictures and videos from the two-day event on Sept. 7–8, and follow the #NASASocial hashtag on Twitter too!

Rosetta Finally Found Its Lost Philae Lander

Rosetta's OSIRIS camera team has found the silent Philae lander on the surface of comet 67P

Nearly two years after its historic landing on comet 67P/Churyumov-Gerasimenko, ESA’s lander has finally been spotted in an image from the orbiting Rosetta spacecraft—PHILAE HAS BEEN FOUND!
