Watch LADEE Launch to the Moon with The Planetary Society
Live Webcast Begins HERE at 7:30pm PDT / 10:30pm EDT
Posted by Mat Kaplan on 2013/09/06 08:45 CDT
Starting at 7:30pm PDT/10:30pm EDT, we will webcast a special event around the launch of NASA's next lunar spacecraft. Watch our special coverage with lunar scientists and live video from the launch site, as well as NASA TV footage of the launch itself.
Just four months ago I posted about a paper recently published by Leslie Young and coauthors that described three possible scenarios for Pluto's atmosphere. Yesterday, Cathy Olkin, Leslie Young, and coauthors posted a preprint on arXiv that says that only one of those scenarios can be true. And it's a surprising one. The title of their paper says it all: "Pluto's atmosphere does not collapse."
An interview with Bruce Murray from 2001 about his perspectives on Mars science and exploration: past, present, and future.
What Venus Express' Visual Monitoring Camera images of Venus have taught us about the motions of Venus' atmosphere.
By now I hope that everyone has seen some of the spectacular images of the Saturn system (and especially Titan!) from the Cassini-Huygens mission. However, the measurements that often make my heart race are taken by instruments that reveal Titan in ways that our eyes cannot see.
United States Geological Survey scientist Ken Herkenhoff posts regular updates on the Curiosity science team's plans for the rover on Mars.
Caution: Spacecraft Under Construction
Visiting JPL's high bay clean room with NASA Administrator Charles Bolden
Join Emily Lakdawalla and Mat Kaplan inside JPL's High Bay 1, where two Earth-revealing missions are being readied for launch.
Yesterday, the Curiosity mission released the video whose potential I got so excited about a couple of weeks ago: the view, from Curiosity, of Phobos transiting Deimos in the Martian sky. In this post, Mark Lemmon answers a bunch of my questions about why they photograph Phobos and Deimos from rovers.
Does Pluto have an ocean under its ice? If it doesn't now, did it ever have one? How will we know?
They're too far apart to have a party, but today Curiosity and Opportunity could have rung in the New Mars Year. Today Mars reached a solar longitude of zero degrees and the Sun crossed Mars' equator, heralding the arrival of spring in the northern hemisphere and autumn in the southern hemisphere.
Last Thursday at the Pluto Science Conference there was a surprising and interesting talk by Amanda Zangari, who pointed out a serious problem with Pluto cartography.
My roundup from notes on the day's presentations on dust in the Pluto system and the surfaces and interiors of Pluto and Charon.
The International Association of Geomorphologists' "planetary geomorphology image of the month," contributed by Joe Levy, features water tracks on Earth and compares them to recurring slope lineae on Mars.
It had never occurred to me to think about geostationary satellites in Mars orbit before reading a new paper by Juan Silva and Pilar Romero. The paper shows that it takes a lot more work to maintain a stationary orbit at an arbitrary longitude at Mars than it does at Earth.
Arecibo Observatory is known for its 1000-foot diameter telescope and its appearances in Goldeneye and Contact. Aside from battling Bond villains and driving red diesel Jeeps around the telescope (grousing at the site director about the funding status of projects is optional), several hundred hours a year of telescope time at Arecibo go toward radar studies of asteroids.
A look at an older paper describing Galileo's possible sighting of individual ring particles orbiting Jupiter as companions to its inner moon Amalthea.
Planetary Society Hangout: A Day in the Life of the Opportunity Rover with Emily Dean
Thursday, May 9, at noon PDT/1900h UTC
Thursday, May 9th, at noon PDT/3pm EDT/1900h UTC, we are joined by Emily Dean, who works on the camera team for the Opportunity rover on Mars.
Note the special time! In this week's Planetary Society hangout at 5pm PDT / midnight UTC, I'll talk with MESSENGER deputy principal investigator Larry Nittler about what MESSENGER has accomplished in its prime and extended missions at Mercury, and what it stands to do if awarded a mission extension.
