Emily Lakdawalla is an internationally admired science communicator and educator, passionate about advancing public understanding of space and sharing the wonder of scientific discovery.
Emily holds a Bachelor of Arts degree in geology from Amherst College and a Master of Science degree in planetary geology from Brown University. She came to The Planetary Society in 2001. She has been writing and editing the Planetary Society Blog since 2005, reporting on space news, explaining planetary science, and sharing beautiful space photos. Emily has been an active supporter of the international community of space image processing enthusiasts as Administrator of the forum UnmannedSpaceflight.com since 2005. She is also a contributing editor to Sky & Telescope magazine.
Her first book, titled The Design and Engineering of Curiosity: How the Mars Rover Performs Its Job, was published by Springer-Praxis in March, 2018. The book explains the development, design, and function of Curiosity with the same level of technical detail that she delivers in the Planetary Society Blog. A second book, Curiosity and Its Science Mission: A Mars Rover Goes to Work will follow in 2019.
Hooray! Curiosity has triumphantly returned to drilling with a successful drill and delivery to its lab instruments at a site named Duluth. It's now studying the dust storm as it drives to new drill sites on Vera Rubin ridge.
Ryugu has continued to grow in Hayabusa2's forward view, resolving into a diamond-shaped body with visible bumps and craters! They've done hazard searches, optical navigation imaging, and measured the rotation rate at 7.6 hours.
On June 3, Hayabusa2 ended use of its ion engines, for now, and is coasting the remaining distance toward Ryugu. It's using an optical navigation camera to image the asteroid's position against a field of background stars to help it navigate.
Blue boxes denote digital terrain models (DTMs). Green boxes are stereo pairs that are also available as anaglyphs. Purple box indicates an image pair that could potentially be converted into an anaglyph/DTM. Yellow line indicates Opportunity's traverse as of February 2014. Underlying CTX image is at 10 meters per pixel.
This animation of front Hazcam images shows the first successful drill for Curiosity in a year and a half, using the new feed-extended drilling technique. It begins with just drill rotation, but as progress slows, Curiosity turns on drill percussion to help it proceed. You can see when percussion turns on by the disturbance of sand on the block of rock, moved by transmitted vibrations.
As of June 2018, Curiosity has drilled and sampled at 16 locations on Mars. They are (left to right and top to bottom): John Klein, drilled on sol 182; Cumberland, on sol 279; Windjana, on sol 621; Confidence Hills, on sol 759, Mojave, on sol 882; Telegraph Peak, on sol 908; Buckskin, on sol 1060; Big Sky, on sol 1119; Greenhorn, on sol 1137; Lubango, on sol 1320; Okoruso, sol 1332, Oudam, sol 1361; Marimba, sol 1422; Quela, on sol 1464, Sebina, sol 1495, and Duluth, sol 2057. All of these images were taken with the MAHLI camera on the end of the arm from a distance of about 5 centimeters, except for the Sebina one, which was taken from 25 centimeters away and enlarged to match the extent of the others. The drill holes are 1.6 centimeters wide. Most are 6.4 centimeters deep, except for Duluth, which is slightly shallower.
