With the announcement of Curiosity's detection of methane on Mars, Nicholas Heavens gives us a guide to the history of methane detection on Mars, a discussion of its scientific significance, and a few things to consider when hearing about and asking about the detection.
The YORP effect is a phenomenon that affects the rotation rate and pole orientation of an asteroid. YORP is an acronym that combines four scientist’s names: Yarkovsky, O’Keefe, Radzievskii, and Paddack.
Last month, the Earth's longest-lived and most traveled robot on another planet drove into a network of fractures the likes of which the scientists had never seen before on Mars and wound up working there through the end of the month – and then something not completely unexpected happened.
With the release of the official Announcement of Opportunity (AO) early in November, NASA has officially begun the competition to select its next low cost ($450M) Discovery program planetary mission. Because planetary scientists are free to propose missions to any destination in the solar system other than the sun and Earth, these competitions bring out the creativity in the planetary science program.
The OSIRIS-REx project released Bennu’s Journey, a movie describing one possible history of our target asteroid – Bennu. The animation is among the most highly detailed productions created by Goddard’s Conceptual Image Laboratory.
On Monday, Jason Callahan published an article in The Space Review discussing the importance of aligning the goals of federally funded scientific communities with national priorities. This post highlights some of the main points of the article and suggests a possible role for The Planetary Society.
As winds whirled and converged to the west of Endeavour Crater, Opportunity's power dropped dramatically in October, but the Mars Exploration Rover (MER) pressed on. By month's end, the robot field geologist had completed her assignments – including capturing the first close-in shot of a comet from the surface of the Red Planet – and was roving onward through the darkness, driving the mission into the 130th month of what started out more than 10-and-a-half years ago to be a 3-month tour.
On October 17-19, 2014, the Lunar and Planetary Laboratory on the University of Arizona campus hosted the second annual Art of Planetary Science exhibition. This exhibition featured works of art inspired by the solar system, alongside works by scientists created from their scientific data.
While the winds of Martian spring blew through Meridiani Planum in September, Opportunity reformatted its Flash memory then continued exploring Wdowiak Ridge on the western rim of Endeavour Crater. Even though the Flash-related issues soon returned, the robot field geologist hardly seemed to notice as it sent home two spectacular panoramas, presented the scientists with a rocky Martian mystery, and delivered yet another September to remember for the mission. And that's not all.
Mars Orbiter Mission (MOM) began its science activities fully on Wednesday with all five science instruments being activated. And on Tuesday, an ISRO-NASA Mars working group was formed which will "seek to identify and implement scientific and technological goals that NASA and ISRO have in common regarding Mars exploration."
NASA's immense reference collection got a makeover at its Washington, D.C. location recently. Jason Callahan gives you a glimpse behind the scenes as guests made their way into the new rooms while enjoying good conversation and, of course, Moon Pies.
There was celebration in the Mars mission control room in Bangalore on Monday following the success of the crucial four-second test firing of the Mars Orbiter Mission’s (MOM) 440-Newton liquid apogee motor. MOM will now go ahead with the nominal plan for the Mars orbit insertion on September 24 at 07:30 IST (02:00 UT / September 23 19:00 PDT).
Nagin Cox, a systems engineer and manager at the Jet Propulsion Laboratory currently working on the mission operations team for Curiosity, tells us about a trip she took to Pakistan as an ambassador for science and technology.
The Mars Express Flight Control Team at ESOC have been actively preparing for the flyby of comet C/2013 A1/Siding Spring on October 19. Initial estimates gave the possibility that Mars Express might be hit by 2 or 3 high-speed particles. Happily, additional observations by ground and space telescopes have shown the risk to be much lower – and perhaps even as low as zero. In today's blog post, the team explain how this (happy!) real-life, real-time development is affecting their preparations for fly-by.
The history of planetary exploration repeats itself starting with a resurgent program in the 90s and 2000s that launched a new fleet of planetary spacecraft. Like our first story, this great success rewarded by deep budget cuts.
Comet Siding Spring is going to make a very close approach to Mars in October. Any comet dust that reaches Mars has the potential to inflict significant damage on the spacecraft orbiting the planet. As it turns out, however, Mars and its orbiters are likely to see very few, if any, impacts. Why?
The first three decades of planetary exploration tell a story that sounds all-too-familiar to modern day space advocates. Growth, peak, and then collapse of hard-earned capability. This is the story of planetary science for the first half of its existence.
After setting the new off-Earth rover distance record in July, Opportunity roved on in August, driving south along the eastern edge of Endeavour Crater's western rim to Wdowiak Ridge on its journey to the next big destination, Marathon Valley.
NASA has explored the solar system since the 1960s, but it has rarely been the top priority for the space agency. Jason Callahan breaks down how planetary science has been funded over the years within NASA's larger budget.
Opportunity just completed its first drives upslope on its long journey toward the crest of the highest rim segment of Endeavour crater, “Cape Tribulation.” Larry Crumpler gives us an update on what to expect next from the little rover that could.
It's official: Opportunity has traveled farther and lived longer than any other vehicle on another planet, driving to a place in history with an out-of-this-world distinction no one even imagined when the robot field geologist left Earth 11 years ago.
Beaming scientists all around, spectacular images on large TV screens, and the best - or at least most exciting - yet to come: such was the extraordinary scene at the European Space Operations Centre in Darmstadt, Germany, today as the European Space Agency's Rosetta spacecraft reached its cometary destination.
The asteroid community recently gathered in Helsinki, Finland for the 12th Asteroids, Comets, and Meteors Conference. As this meeting showed, one of the hottest topics in asteroid science is the study of asteroid families.
Venera 9 and 10 landed on Venus in 1975 and sent back the first images of the planet's surface. Now, Ted Stryk brings new life to these images to show us what it would be like to stand on the Venusian surface.
In 1979, the Voyager 1 probe took a stunning series of images on its final approach to Jupiter. Thirty-five years later, almost to the day, a group of seven Swedish amateur astronomers set out to replicate this odyssey, but with images taken with their own ground-based telescopes.
This week the OSIRIS-REx team gathered at the Lockheed Martin facility in Denver to perform a “Design Reference Mission (DRM)” walkthrough. The DRM is basically the battle plan for OSIRIS-REx for accomplishing our goal of returning pristine samples from asteroid Bennu.
At the western rim of Endeavour Crater, Opportunity spent the month of May exploring a new clayground along Murray Ridge and the Mars Exploration Rovers (MER) mission trundled into the 125th month of what was originally to be a short, 3-month tour.
The construction of OSIRIS-REx has begun! Seeing the core structure being assembled demonstrated that OSIRIS-REx is no longer just a set of drawings and PowerPoint charts, it is starting to become a real spacecraft.
