Spirit Returns More "Exquisite" Data, Inspires New Generation of Space Explorers
Spirit continues to return
Spirit: A Star is Born, A Space Agency and A Nation Are Lifted
If a Hollywood screenwriter had crafted the scenes for the last few days of the Spirit Mission Team at JPL as they really happened -- success after success, triumphant image after triumph he or she would be out of a job.
Spirit Spends First Full Days on Mars; Scientists Report "More Good News"
With additional data due later today and early tomorrow morning, the mission team is hoping to receive and piece together the first color picture perfect panoramic postcard -- from the PanCam, a high resolution stereo vision camera -- for the briefing tomorrow.
Mars Exploration Rovers Update: Spirit Lands on Red Planet, Returns First Images
Spirit -- NASA's first Mars Exploration Rover -- survived the 'six minutes of terror' entering and descending through the atmosphere to land safely -- and upright -- in Gusev Crater on the Red Planet. Just two hours after the confirmation signal of the landing, the first engineering data and images began streaming into the MER Mission Control at the Jet Propulsion Laboratory (JPL), where Spirit and her twin, Opportunity were built.
Mars Rover 'Alive and Well' Returning More Images
Spirit spent a quiet, cold night in Gusev Crater, and woke up to return streams of new data, including more black and white 'postcards' from Mars.
NASA Begins Countdown to Spirit's Arrival on Mars
Spirit – the first of NASA's two robot geologists en route to the red Planet -- is “in “excellent” health, NASA and JPL scientists reported at a news briefing at JPL this afternoon, and the countdown to touch down on the Red Planet has begun.
No Icecaps at the Lunar Poles
New observations reported this week in the journal Nature have cast doubt on the theory that thick deposits of ground ice lie conveniently close to the surface in permanently shadowed crater floors at the lunar poles.
Researchers Discover Lakes on Titan
Recent radar observations of Saturn’s moon Titan have produced the first direct evidence that the second largest moon in the solar system may be hiding pools of liquid hydrocarbons underneath its smoggy atmosphere.
New and Improved SETI@home will Form the Backbone of Distributed Computing Network
SETI@home and BOINC are gradually converging, and the benefits for both are substantial. While SETI@home enjoys the increased flexibility of the BOINC platform, it brings to BOINC something of inestimable value to a distributed computing project: millions of SETI@home users, willing to use their computers' processing power for the advancement of scientific research.
Analyzing the Reobservations
SETI@home chief scientist Dan Werthimer and his team went back to Arecibo to reobserve the most promising candidate signals detected by the project so far. Unlike most of the year, when SETI@home piggy-backs on the regular operations of the telescope, this time the Werthimer's crew had the full use of the resources of the giant dish.
Watching Spirit Launch to Mars
Spirit has successfully launched to Mars, and I was there with members of the science team to witness it.
Scientists Detail Ambitious Goals of Mars Express
Scientists working on the European Space Agency's (ESA's) Mars Express detailed the mission's ambitious plan to study Mars from the top of its atmosphere to several kilometers beneath its surface, at a press conference in London, England last week.
Reobservations Report No. 8: Beyond the Countdown: SETI@home Makes Plans for the Future
SETI@home's Stellar Countdown has come to an end at the Arecibo Radio Observatory. All in all the Stellar countdown observed 227 promising locations in the sky. Within the next few weeks all the data collected and recorded will be processed by SETI@home users around to world.
Reobservations Report No. 7: On Last Day at Arecibo, SETI@home Turns to Distant Planetary System
After getting bumped off the telescope last week to make way for Solar flare observations, SETI@home Chief Scientist Dan Werthimer and his crew will spend 14 hours today observing the locations of SETI@home's most promising candidate signals, as well as a few other interesting locations.
Reobservations Report No. 6: Solar Intervention Postpones SETI@home Reobservations
SETI@home's plans to reobserve its most promising candidate signals were interrupted today by the unexpected intervention of a Solar flare.
Reobservations Report No. 5: First Observation Session Completed at Arecibo
The SETI@home team has completed the first of its three 8-hour observation session at Arecibo, designed to revisit the most promising candidate signals detected so far by SETI@home.
Reobservations Report No. 4: Results in Real Time
SETI@home scientists will have to wait for several weeks for the full analysis of the data collected during the reobservations. But even while the observations are going on at Arecibo, they will already have a good idea if they have found something significant.
Reobservations Report No. 3: Selecting the Finalist Candidates
For three successive days SETI@home will have use of the giant Arecibo radio telescope to revisit the most promising candidate signals detected since the project was launched in 1999. SETI@home Chief Scientist Dan Werthimer and his team put together a list of the
Reobservations Report No. 2: Reobserving, Recording, and Reprocessing
For the first time during the reobservations, Werthimer and his crew will have use of another recorder. This is Arecibo's
Reobservations Report No. 1: Shifting Gears at Arecibo
In the next few days, SETI@home Chief Scientist Dan Werthimer, along with team members Eric Korpela and Paul Demorest, will head down to Arecibo in Puerto Rico. There, at the site of the largest radio telescope in the world, they will begin a new chapter in the short history of the project: the reobservation of SETI@home's most promising candidate signals.
