NASA Mars Rover Opportunity Lifts Off 155

Posted by michael from the lawn-dart dept.
Joost Schuur writes "At 11:18 PM EDT on Monday, Opportunity, the second of 2 NASA Mars Exploration Rovers took off aboard a Boeing Delta 2 Heavy rocket after several delays and begun its 305 million mile trip to the Red Planet, where it will join its sister vehicle Spirit, which launched June 10th. Spirit and Opportunity will land on opposite sides of Mars, travelling up to 40 meters a day, and use a series of instruments to search for water, including the Rock Abrasion Tool, which will grind into rocks to give scientists a peak inside. Things are going to get crowded next January in orbit, as both NASA missions join the European Mars Express mission also launched this month and the Japanese Nozomi probe, which would finally complete its troublesome 5 year journey. Those stuck on Earth can take advantage of the closest Mars opposition in 60,000 years and watch with a telescope, or follow the images provided by the International MarsWatch 2003 group."

    Its good to see NASA responding well with some serious missions after the Atlantis disaster. After all the cutbacks during the Clinton era I really thought it might get to the point where they did nothing but put satellites into orbit.

    What would really interest me however would be if they switched their attention from Mars to Venus. Most scientists agree that life on Mars is not feasable wheras Venus, which is closer to the sun, has a far more interesting chemical makeup. Although too hot for any carbon based lifeforms to be found, many scientists have thought that in Venus's rich ammonia lakes a Silicon based life could have emerged. Although these would be very basic forms of life (not as advanced a monkeys) discovering them would mean that we could no longer view ourselves as being at the center of the universe.

      I guess as the others pointed out, you were referring to Columbia and STS-107.

      Actually I am pretty sure this mission has been in the books for quite sometime. Especially since Earth and Mars are supposed to be in the closest configuration with respect to their orbits. A trip to Mars right now will take approximately 7-8 months and the two rovers(Spirit and Opportunity) should get to Mars by January.

      Also, its not just NASA which has used the current orbit position as an advantage; the European Space Agency(ESA) and the Japanese Space Agency(NASDA i think) have also launched their respective payloads to Mars.

      About Venus, I doubt if NASA will come out with a program. A whole load of factors , not the least scientific goes into allocating budget to programs. And especially right now, I would think it would be really hard for NASA to convince the govt., to fund a program to Venus. The question of selling it to the public ranks high up there among the criteria and seems tough to me.

      It's not so hard. Each mission is on a separate frequency, so you just add extra receivers to share each ground antenna. Even the largest DSN antennas have beamwidths wide enough to take in all of Mars plus the nearby orbital space. (A 64m dish has a beamwidth of about 144 arc-seconds at X-band, while Mars as seen from Earth is currently about 20 arc-seconds in diameter.)

      Also remember that Spirit and Opportunity are going to opposite sides of the planet, so generally only one will use the DSN at a time.

        Oh, another thing helping the crunch at the DSN is the end of the Galileo mission. When the X-band high gain antenna failed to deploy, the S-band omni antenna was used to salvage the mission.

        This placed an enormous strain on the DSN's resources. The very low data rate required more tracking time to transfer a given amount of information, and multiple antennas at each site were often arrayed to increase the received signal. The end of Galileo frees these antennas for other missions.

        I visited the Canberra DSN site in September 1997. While I was there, Jupiter rose and most of the antennas at the site were pointed at it. Very impressive to see them all moving together.

        With that said, the DSN is getting up there in age and many of the antennae need upgrading and/or replacing. Hopefully, there will be budget money in the coming years to deal with this.

      I'm not sure how valid of a claim that is. Certainly, right now our probes aren't that great, mainly because there is little actual autonomy. However, in the near future, probes will be built to handle major decisionmaking on their own. Our best hope for exploring the most of Mars is to send thousands of small autonomous probes that will do the looking around for us. This could be done for roughly the same cost as the manned mission, without the PR risk (yes, I hate it but it's very true) that manned missions currently represent.

      I work at the Jet Propulsion Lab, and many [nasa.gov] of the robotics [nasa.gov] technologies [nasa.gov] that are currently being persued [nasa.gov] there should give us the capability to collect huge amounts of useful data on Mars in the next 20 years or so.

      Is manned flight expensive? Well not really, but the price/performance ratio isn't that great compared to what will be done in the next 20 years with robotics probles (remember economy of scale, 1000 probes isn't much more expensive to build than 1).
