Learn the rocket equation, part 2
In the second and final chapter of our series, we’ll explore what the rocket equation has to say about travel through the solar system, using the example of launching a rocket to Pluto.
HERA crewmember shares thoughts ahead of simulated 45-day asteroid mission
Tonight, a four-person crew will seal themselves inside a three-story habitat at NASA's Johnson Space Center, kicking off a simulated 45-day mission to an asteroid. One crewmember shares his thoughts before entering.
Earth's ring system: This mosaic shows 46+ geostationary satellites in one image
Astrophotographer Adam Block captures 46 geostationary satellites, plus some unnamed stragglers, in one 10-frame image mosaic.
Planetary Science Just Got Its Best Budget in Years
The President signed the Consolidated Appropriations Act of 2017, funding the U.S. government for the remainder of the fiscal year. NASA got a boost to $19.65 billion, and its Planetary Science Division saw a budget increase to $1.846 billion—its best budget in more than ten years.
Old documents shine new light on NASA's plan to send a solar sail to Halley's Comet
The Planetary Society's LightSail project has roots in a late-1970s NASA plan to send a giant solar sail spacecraft to Halley's Comet. Now, a cache of archival documents adds new depth to the audacious plan.
A Tribute to Nathan Bridges
Last week, the planetary science community lost Nathan Bridges, a leading scientist whose work studied how wind sculpts the surface of Mars. Nathan was a prolific scientist involved in many Mars exploration missions, a charter member of The Planetary Society, a friend, husband, and father.
Field Report from Mars: Sol 4718
Opportunity has made the final drive in the month-long process that began way up north inside Endeavour Crater earlier this Earth-year.
The Mars Exploration Rovers Update: Opportunity Closes in on Perseverance Valley
Opportunity spent the month of April 2017 outside the western rim of Endeavour Crater, cruising toward Cape Byron and Perseverance Valley, the centerpiece of its tenth extended mission.
Dawn Journal: On Course for Opposition
The Dawn spacecraft is about to swing into a new orbital path to observe the enigmatic
Learn the rocket equation, part 1
Have you ever wanted to learn the fundamental physics behind one of the most basic concepts of rocket science? In part one of our two-part series, we explore the foundations of the famous rocket equation.
Trusty Cassini survives first dive between Saturn and its rings
Cheers erupted in the Von Karman auditorium at the Jet Propulsion Laboratory early Thursday morning as a squiggly green line on a graph developed a crisp, tall peak, signifying that the Cassini spacecraft was calling home after surviving its first plunge between Saturn and its ring system.
The first Space Launch System flight will probably be delayed
NASA's new heavy lift rocket is currently scheduled to launch the Orion spacecraft on a test flight next year. But all signs are pointing to a probable delay.
Curiosity update, sols 1600-1674: The second Bagnold Dunes campaign
The four-stop dune science campaign offered the engineers some time to continue troubleshooting the drill without any pressure to use it for science. They scooped sand at a site called Ogunquit Beach but couldn't complete the planned sample activity because of new developments in the drill inquiry. The rover has now headed onward toward Vera Rubin Ridge.
This weekend, it's the beginning of the end for Cassini
NASA's long-lived Cassini spacecraft is about to buzz Titan for the final time, putting it on course for a spectacular mission finale that concludes in September.

The annual Space Symposium brings together space leaders from around the world to discuss, address and plan for the future of space.
Fossils or good-looking rocks? Why searching for life on other worlds is hard
If you find a structure that looks like ancient life, can you be really sure that it is ancient life?
Another smoking gun in the search for life in Enceladus’ ocean
NASA's Cassini spacecraft sniffed out molecular hydrogen spewing from Enceladus' subsurface ocean. The discovery means Saturn's moon has all the basic ingredients needed to support life.
