ROCHESTER, N.Y.--(BUSINESS WIRE)--

ITT Exelis (XLS) and the NASA Langley Research Center completed a flight campaign in March that measured carbon dioxide over various surfaces and conditions as a step toward taking active global measurements from space.

Using a NASA DC-8 aircraft and an instrument built by Exelis called the Multifunctional Fiber Laser LIDAR (Light Detection and Ranging), the team took carbon dioxide measurements from various, challenging environments. The information was gathered from high altitudes over fresh and aged snow surfaces, ocean surfaces in high winds, tall coastal and forest conditions, and in the presence of thin cirrus clouds.

The science community has stated clearly, the ability to improve climate models depends directly on our ability to obtain more accurate CO measurements, said Eric Webster, vice president of Exelis weather systems. Using our active LIDAR system from space would enable significant improvements in global mapping of carbon sources and sinks and thus improve climate models. Results over several years and dozens of flights, including this campaign, prove our solution works and would provide decision-makers with more accurate information.

In 2007, the National Research Council released its decadal survey recommending the use of an active LIDAR system to provide new information on carbon dioxide processes over all regions of the Earth, during night and day. NASA Langley Research Center is evaluating the Exelis instrument to determine its effectiveness for the mission. The Exelis instrument is based on commercially viable fiber communications technology, which makes it lower cost and risk than other approaches.

Using active LIDAR is important for researchers because current passive instruments for measuring CO from space cannot take measurements at night, at high latitudes where major cities are located, or through clouds, which limits effectiveness. Active instruments also take more accurate measurements in the lower atmosphere where increases and decreases in carbon dioxide take place more often.

Exelis has won three related technology development grants from the NASA Earth Science Technology Office, and is on its ninth task under an indefinite-delivery, indefinite-quantity contract with the NASA Langley Research Center for evaluation of LIDAR technology. The most recent flight campaign also included instruments from the NASA Goddard Space Flight Center and from NASAs Jet Propulsion Laboratory to quantify various approaches. The NASA Langley Research Center and Exelis are working on the next step in the evaluation process, which is to move the measurement concept to a high-altitude unmanned aerial vehicle.

Dissatisfied with the current state of the solar system, NASA is looking to do a little remodeling.The space agency is angling to capture a small asteroid and drag it closer to Earth for human exploration, the Associated Press reported April 6. The Obama administration's proposed budget for 2014 will include $100 million to kick off the project, Senator Bill Nelson of Florida, chair of the Senate Subcommittee on Science and Space, told reporters. Nelson's statements confirmed a March report in Aviation Week about the mission.The idea is to accelerate human exploration of the solar system, particularly the bodies that have never seen human visitors--namely, everywhere except Earth and the moon. Back in 2010, President Obama announced his intention to send human explorers to a near-Earth asteroid by 2025 and to Mars sometime in the 2030s. According to the AP, under the new plan a robotic craft would snag a yet to be-selected asteroid in 2019 and return it to the vicinity of the moon for a human spacewalking mission two years later.The plan builds on a proposal examined in a 2012 report from the Keck Institute for Space Studies (KISS) at the California Institute of Technology. In that report, an expert group estimated that a robotic probe could capture a seven-meter, 500,000-kilogram asteroid and haul it back to lunar orbit for exploration by 2025. That alone would cost about $2.6 billion, according to the KISS report (pdf), but somehow the version of the plan described to NBC News by an anonymous Obama administration source would do the same thing four years faster for less than half the cost. (Magic 8-Ball says: "Don't Count on It.")Details aside, what's the point of going to an asteroid? The KISS report highlights a few justifications, including the planetary science benefits of the first asteroid "dissection," as well as the planetary defense benefit of anchoring to an asteroid, which may someday prove useful if a space rock is found to be on a dangerous trajectory and needs to be rerouted. What is more, an asteroid mission could open the door to the spaceborne extraction of precious materials, as has been proposed by Planetary Resources, Inc. (which bills itself as "The Asteroid Mining Company").But the real advantage of asteroid exploration is that astronauts could simply sidle up to a small space rock without the need for a costly, complex landing module, as is required to negotiate the gravitational pull of a larger body such as Mars or the moon. The downside is that the idea of an asteroid mission has hardly stoked the passion of the public since it was first announced three years ago. And it is hard to imagine a spacewalking exploration of a dusty little rock with a name like 2008 EV5 garnering the same excitement as a mission to an object that looms large in the night sky and in our imagination.In his remarks to reporters, Nelson called the asteroid mission "a clever concept." One of my esteemed colleagues calls it "batsh*t crazy." I'd say it's somewhere in between. On one hand, it does feel a bit like "make-work," as my colleague put it--creating a destination just so we have somewhere to go. On the other hand, no human being has left low Earth orbit in 40 years. And if it's an asteroid expedition that breaks that drought, I'll take it.

NASA Getting into the Asteroid-Moving Business

NASA has selected five planet hunters to receive the 2013 Carl Sagan Exoplanet Postdoctoral Fellowships. The fellowship, named for the late astronomer, was created to inspire the next generation of explorers seeking to learn more about planets, and possibly life, around other stars.

The primary goal of the fellowship program is to support outstanding recent postdoctoral scientists in conducting independent research related to the science goals of NASA's Exoplanet Exploration Program.

Significant discoveries have already been made by previous Sagan Fellows. One recent discovery found that the size and location of an asteroid belt may determine whether complex life will evolve on an Earth-like planet

"In the past decade, astronomers have made incredible progress toward Carl Sagan's goal of understanding the existence of life, and ultimately, of intelligent life throughout the universe," said Charles Beichman, executive director of the NASA Exoplanet Science Institute at the California Institute of Technology in Pasadena. The young scientists named as this year's Sagan Fellows will help to make dramatic new progress toward this goal through their observational, theoretical and instrumental contributions."

The program, created in 2008, awards selected postdoctoral scientists with annual stipends of $65,500 for up to three years, plus an annual research budget of up to $16,000.

The 2013 Sagan Fellows:

-- Jared Males, who will work at the University of Arizona, Tucson, to investigate exoplanetary habitability by perfecting instrumentation to image Jupiter- and Saturn-sized planets in the liquid- water habitable zone of nearby stars.

-- Katja Poppenhaeger, who will work at the Harvard Smithsonian Center for Astrophysics, Cambridge, Mass., to explore how stars and close-in planets influence each other's evolution over time.

-- Jacob Simon, who will work at the Southwest Research Institute, San Antonio, to understand the formation of planets out of gas and dust disks.

-- Jennifer Yee, who will work at the California Institute of Technology, Pasadena, Calif., to measure the frequency of massive planets around low mass stars using microlensing.

NASA Selects 2013 Carl Sagan Fellows

WASHINGTON As NASA begins to apportion the 5 percent budget cut mandated under sequestration, parts of the U.S. space agency are being asked to cough up more so that others can cough up less or be spared altogether, a senior NASA official told an advisory panel April 4.

NASAs Planetary Science Division, which Congress favored with a $200 million increase in the Full-Year Continuing Appropriations Act of 2013 (H.R. 933) that President Barack Obama signed into law March 26, is expected to lose most if not all of that money as sequestration siphons some $900 million off the agencys enacted $17.5 billion top line.

James Green, NASAs Planetary Science Division director, told members of the NASA Advisory Councils planetary science subcommittee not to expect a straight 5 percent across-the-board cut as the agency rolls its top line back to $16.6 billion, as required under sequestration.

In order to protect higher-priority programs, Green said, NASA will be cutting lower-priority programs, including planetary science, by more than 5 percent. [Planetary Science Takes Budget Hit in 2013 (Infographic)]

We are not a protected program, we are not a high-priority program, Green told his fellow planetary scientists. Consequently, you can assume that [the Planetary Science Divisions reduction] would be higher.

Green did not say which agency programs would be spared, but NASA Administrator Charles Bolden has previously identified the James Webb Space Telescope, the Space Launch System heavy-lift rocketand the Commercial Crew Program as top administration priorities.

The agency had already informed Congress that certain things will be protected, Green said. So we will have a reduced program below the funding Congress has provided.

Congress included $1.39 billion in H.R. 933 for NASAs Planetary Science Division a $200 million increase compared with the $1.19 billion the division was getting under a stopgap spending bill that expired March 27.

The exact amount of funding planetary science will losewill not be known for about a month, when NASA sends Congress its proposed operating plan for the remainder of 2013, Green said.

If planetary science loses too much of the increase it got from Congress, it could spell the end of Greens plan to solicit proposals next year for a Discovery-class mission that would launch around the end of the decade.

NASA Planetary Science Bracing for Brunt of Sequester Cuts

The United States has no immediate plans to send astronauts back to the Moon, according to NASA administrator Charles Bolden.

"I don't know how to say it any more plainly. NASA does not have a human lunar mission in its portfolio and we are not planning for one," Bolden said late last week at a joint meeting of the Space Studies Board and the Aeronautics and Space Engineering Board (ASEB) in Washington, according to Space Politics.

Bolden was responding to a suggestion by UCLA chancellor emeritus and professor Al Carnesale, who leads a group formulating NASA's strategic direction, that the space agency delay a proposed crewed mission to visit an asteroid by 2025 and instead consider returning to the Moon.

"There's a great deal of enthusiasm, almost everywhere, for the Moon. I think there might be, if no one has to swallow their pride and swallow their words, and you can change the asteroid mission a little bit ... it might be possible to move towards something that might be more of a consensus," Carnesale was quoted as saying by Space Politics.

Nearly three years ago, President Barack Obama announced the country's goal of sending astronauts to a near-Earth asteroid during a speech at the Kennedy Space Center. Apollo 11 astronaut Buzz Aldrin, present at the Kennedy Space Center speech, "has been [to the Moon] ... There's a lot more of space to explore, and a lot more to learn when we do," Obama said at the time.

Aldrin and Neil Armstrong, with Michael Collins piloting the lunar command module, became the first humans to set foot on the Moon on July 21, 1969. Apollo 17 crew members Eugene Cernan, Harrison Schmitt, and Ronald Evans were the last in the program to visit Earth's satellite, with Cernan and Schmitt spending four days on the lunar surface in December 1972.

Last May, it was reported that NASA had begun training astronauts for an asteroid mission. In recent years, the space agency has also been focused on planning a manned trip to Mars. One part of those ambitious projects could involve constructing a space station in fixed lunar orbit, which could serve as a launching pad for manned interplanetary missions.

But some in the space community are apparently unhappy with those ambitious plans, according to Carnesale.

"The more we learn about it, the more we hear about it, people seem less enthusiastic about it," he was quoted as saying at last Thursday's meeting in Washington.

Bolden, however, stressed that changing NASA's agreed-upon, long-term objectives would be counter-productive.

NASA: Forget the Moon, Let's Play Asteroids

NASA chief Charles Bolden says the space agency won't be sending astronauts to land on the moon any time soon, according to press reports.

The U.S. space agency won't lead the way back to the moon in the foreseeable future in order to maintain its focus on manned missions to an asteroid, and eventually Mars, Bolden said during a joint meeting of the Space Studies Board and the Aeronautics and Space Engineering Board last Thursday (April 4), according to aSpacePolitics.com report by Jeff Foust.

"NASA will not take the lead on a human lunar mission," Foust quoted Bolden as saying. "NASA is not going to the moon with a human as a primary project probably in my lifetime. And the reason is, we can only do so many things."

Instead, he said the focus would remain on human missions to asteroids and to Mars. "We intend to do that, and we think it can be done," Bolden said. [Most Amazing Moon Missions in History]

Bolden's comments on new manned moon missions came in response to a suggestion that the scientific community, as a whole, is not enthusiastic about pushing ahead with a manned mission to an asteroid by 2025 an idea endorsed by President Barack Obama in 2010.

In April 2010, Obama called on NASA to pursue the manned asteroid mission as a precursor to sending astronauts to Mars in the mid-2030s. That new space vision, unveiled just after Obama canceled NASA's moon-oriented Constellation program, which sought to send astronauts on new lunar landing missions, in favor of the asteroid and Mars plan.

During the April 4 meeting, Bolden apparently made it clear that NASA does not plan to lead the charge back to the moon's surface.

"I dont know how to say it any more plainly," Bolden said, according to Foust. "NASA does not have a human lunar mission in its portfolio and we are not planning for one."

With Obama now in his second term, Bolden also warned that if the next presidential administration chooses to make another major course change in NASA's human spaceflight program, such a change would mean "we are probably, in our lifetime, in the lifetime of everybody sitting in this room, we are probably never again going to see Americans on the moon, on Mars, near an asteroid, or anywhere. We cannot continue to change the course of human exploration."

NASA made history on July 20, 1969 when Apollo 11 astronauts Neil Armstrong and Buzz Aldrin became the first humans ever to walk to on the moon. Five more successful moon landings would follow until 1972, when the series ended with NASA's Apollo 17 mission.

US Won't Lead New Manned Moon Landings, NASA Chief Says

NASA's robotic Mars explorers are taking a cosmic break for the next few weeks, thanks to an unfavorable planetary alignment of Mars, the Earth and the sun.

Mission controllers won't send any commands to the agency's Opportunity rover, Mars Reconnaissance Orbiter (MRO) or Mars Odyssey orbiter from today (April 9) through April 26. The blackout is even longer for NASA's car-size Curiosity rover, which is slated to go solo from April 4 through May 1.

The cause of the communications moratorium is a phenomenon called a Mars solar conjunction, during which the sun comes between Earth and the Red Planet. Our star can disrupt and degrade interplanetary signals in this formation, so mission teams won't be taking any chances.

"Receiving a partial command could confuse the spacecraft, putting them in grave danger," NASA officials explain in a video posted last month by the agency's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. [The Boldest Mars Missions in History]

Opportunity and Curiosity will continue performing stationary science work, using commands already beamed to the rovers. Curiosity will focus on gathering weather data, assessing the Martian radiation environment and searching for signs of subsurface water and hydrated minerals, officials said Monday (April 8).

MRO and Odyssey will also keep studying the Red Planet from above, and they'll continue to serve as communications links between the rovers and Earth. The conjunction will also affect the European Space Agency's Mars Express orbiter, officials have said.

Odyssey will send rover data home as usual during conjunction, though the orbiter may have to relay information multiple times due to dropouts. MRO, on the other hand, entered record-only mode on April 4. The spacecraft will probably have about 52 gigabits of data to relay when it's ready to start transmitting again on May 1, MRO officials have said.

Mars solar conjunctions occur every 26 months, so NASA's Red Planet veterans have dealt with them before. This is the fifth conjunction for Opportunity, in fact, and the sixth for Odyssey, which began orbiting Mars in 2001.

But it'll be the first for Curiosity, which touched down on Aug. 5, kicking off a two-year surface mission to determine if the Red Planet has ever been capable of supporting microbial life.

"The biggest difference for this 2013 conjunction is having Curiosity on Mars," Odyssey mission manager Chris Potts, of NASA's Jet Propulsion Laboratory in Pasadena, Calif., said in a statement last month.
