To help scientists and engineers follow the action 154 million miles away, the trajectory of the Mars Science Laboratory was set up to make sure the rover's descent to the surface of the red planet occurs within view of three orbiting satellites.

NASA's Mars Odyssey and the Mars Reconnaissance Orbiter, along with the European Space Agency's Mars Express satellite, will capture telemetry from the Mars Science Laboratory as the spacecraft makes its nail-biting seven-minute plunge to the floor of Gale Crater overnight Sunday.

But Odyssey is the only one of the three capable of "bent pipe&… Read more

The question is straightforward: how to get a car-size rover safely to the surface of Mars? And not just anywhere, but to a very precisely defined bull-s-eye on the floor of a broad crater, within roving distance of a 3-mile-high mountain.

In earlier ventures to Mars, spacecraft have either bounced to the surface cocooned in giant airbags or made the trip atop a rocket-powered descent stage. But neither approach was an option for NASA's Curiosity rover, the centerpiece of the $2.5 billion Mars Science Laboratory mission.

Tipping the scales at one ton, the nuclear-powered Curiosity, a rolling laboratory … Read more

In a $2.5 billion gamble, a nuclear-powered Mars rover the size of a small car will attempt a pinpoint landing near the base of a 3-mile-high mountain overnight Sunday to search for the building blocks of life in the frozen history of the red planet and evidence of past or present habitability.

In so doing, the Mars Science Laboratory rover, dubbed "Curiosity" in a student naming contest, will climb layer by layer through vast eras of the planet's enigmatic history, possibly shedding light on the transition from a warmer, wetter past to the arid, frigid world … Read more

MOJAVE DESERT, Calif.--It's hard to imagine a more complete -- and impressive -- collection of aviation facilities and aircraft anywhere on the planet than the one in this vast, arid, wide-open wasteland northeast of Los Angeles.

Thanks to its endless amounts of dry, flat terrain, useless to most people, and the fact that there are only a few ways in -- vital for security -- the Mojave is, and has long been, the beating heart of the aviation world. It's here that Chuck Yeager first broke the sound barrier. And where Burt Rutan's SpaceShipOne ushered in … Read more

A six-second rocket firing Tuesday nudged NASA's Mars Odyssey orbiter into position to relay telemetry from the Mars Science Laboratory back to Earth in near real time during the $2.5 billion rover's rocket-powered descent to the red planet's surface on August 6, officials said.

Odyssey entered "safe mode" July 11 after problems with the craft's attitude control system, raising the possibility that the orbiter might not be properly positioned to relay entry, descent and landing data from the rover back to Earth.

While the Curiosity rover will be sending X-band signal tones directly … Read more

An attempt to re-dock an unmanned Russian Progress supply ship with the International Space Station was aborted by the ship's flight computer Monday night when a new rendezvous system failed to operate as expected, flight controllers said.

By design, the spacecraft ended up on a passive return trajectory that will permit another docking attempt later this week, after engineers have a chance to diagnose what went wrong. The station's six-member crew was never in any danger, officials said.

The Progress M-15M spacecraft was undocked from the station's Pirs module Sunday afternoon and directed to back away to … Read more

Sally K. Ride, the first American woman in space and an advocate for science education, died today after a bout with pancreatic cancer. She was 61.

"Sally Ride died peacefully on July 23, 2012 after a courageous 17-month battle with pancreatic cancer," according to a statement on the Sally Ride Science Web site. "Sally lived her life to the fullest, with boundless energy, curiosity, intelligence, passion, joy, and love. Her integrity was absolute; her spirit was immeasurable; her approach to life was fearless."

In a statement released by the White House, President Obama said "Michelle … Read more

The first Landsat satellite went into orbit 40 years ago today, and during the past four decades, a series of seven different "birds" have trained a watchful eye on Earth from just about the most wicked vantage point around.

The program's youngest eye in the sky, Landsat 7, has been flying since 1999 and will be joined next year by the next-generation Landsat Data Continuity Mission satellite, or LDCM. The LDCM features up-to-date thermal infrared sensors and land-imaging equipment that will make it a full-blown orbiting observatory.… Read more
