Orion's Ride to Space is at the Launch Site. Why So Early?
On Tuesday, Orion's massive Delta IV Heavy rocket rolled from its Horizontal Integration Facility out to the launch site. Launch is still eight weeks away. Why so early?
NASA’s Big Rocket a Step Closer to Reality
NASA's Space Launch System passed a critical milestone yesterday, but buried within the announcement was news that the first launch could slip by nearly a year.
The Planetary Society Supports NASA's Asteroid Initiative
The Planetary Society strongly supports NASA's asteroid initiative, including the goal of redirecting an asteroid to the vicinity of the Moon. But an independent cost estimate is needed, and needed soon.
No, Russia Did Not Just Kick the U.S. Out of the Space Station
A top Russian official announced a ban on Russian engines in U.S. military launches and questioned Russia's long-term commitment to the International Space Station. We cut through the hype and try to understand what was actually said and the immediate consequences facing NASA.
[Updated] To Europa!...Slowly. First Impressions of NASA's New Budget Request
Europa may get a mission...eventually. We give our first take on the 2015 NASA Budget request. How does Planetary Exploration fare? Which projects were cancelled? Will NASA capture an asteroid? And most importantly, what can you do about it?
India keeps up the momentum, returning troubled GSLV to flight
India returned its troubled GSLV to flight Sunday, marking the first successful outing of the country's Cryogenic Upper Stage.
A Protected Class of Programs at NASA?
The House Science Committee is considering giving a select few NASA programs special protected status against cancellation.
Chang'e 3 departs for the Moon, with amazing images and video
On December 1 at 17:30 UTC, Chang'e 3 launched atop a Long March 3B rocket on a direct lunar transfer trajectory. It is scheduled to enter orbit December 6 and land December 14. The rocket was equipped with cameras that recorded thrilling video of the launch and final departure of the probe.
Why are MAVEN and Mars Orbiter Mission taking such different paths to Mars?
Two spacecraft launched for Mars this month: Mars Orbiter Mission on November 5, and MAVEN on November 18. MAVEN is now on an interplanetary trajectory, while Mars Orbiter Mission is still in Earth orbit and will not depart for Mars until the end of the month. A lot of people are asking me: why the difference? Here's your answer, with input from Dave Doody.
MAVEN is on the way to Mars
A perfect launch on an Atlas V rocket has sent MAVEN on her way to Mars today at 10:28 PT (18:38 UT). Today's on-time launch puts the mission on course for a September 22, 2014 arrival at Mars.
MAVEN has arrived at the launch pad
As India's Mars Orbiter Mission continues to pump up the altitude of its orbit around Earth, NASA's MAVEN is making final preparations for its direct-to-Mars launch. All is proceeding acccording to schedule toward its November 18 launch at 1:28 EST / 10:28 PST / 18:28 UTC.
A picture-perfect launch for ISRO's Mars Orbiter Mission
The PSLV carrying ISRO's Mars Orbiter mission shot like a firework off the launch pad today, placing the spacecraft precisely into its planned elliptical orbit of Earth. Now the 10-month cruise phase begins. Congratulations to ISRO!
India prepares to take flight to Mars with the Mars Orbiter Mission (MOM)
The excitement is really building toward India's first-ever attempt at an interplanetary spacecraft! Launch day is quickly approaching for the Mars Orbiter Mission. In this lengthy post, I provide answers to frequently asked questions about the mission and its goals.
India prepares to return troubled rocket to flight
India is preparing for the return-to-flight of their Geosynchronous Satellite Launch Vehicle, which has suffered back-to-back failures.
Pretty picture: An Atlas launch and a very surprised bird
If you take hundreds of photos of every single spacecraft launch you can get to, you will eventually get lucky shots like this one. It was taken by Ben Cooper at today's launch of the U.S. Navy satellite MUOS-2 and features a very surprised turkey vulture in a striking pose in front of the American flag.

Russian rocket crashes in spectacular explosion
A Russian Proton-M rocket veered off course and crashed in a nearby field shortly after liftoff from Baikonur, Kazahkstan.
If we started today, how long would it take to get to Mars? With this budget, never.
The House of Representatives held a hearing today to discuss their proposed NASA authorization bill, which would fund Planetary Science, cut Earth Science, forbid asteroid retrieval, and command NASA to pursue a path to Mars via the Moon.
Ten years since Spirit's launch
Ten years ago, Spirit launched on a Delta II rocket toward Mars, and I was there to see it.
