Cosmic-Ray Fe Intensity Reaches Record Levels in 2008-2009

PDF version

Recent Ulysses data show that during the current solar minimum the interplanetary magnetic field strength and solar wind pressure are at the lowest levels of the space era. Since the solar wind and its embedded magnetic field play key roles in controlling the access of galactic cosmic rays (GCRs) to the inner heliosphere, one might expect that the GCR intensity at Earth would also be at record levels.

The figure above shows ACE measurements of the cosmic-ray Fe intensity near the peak of the cosmic-ray intensity spectrum. Also shown is the projected intensity for 2008-2012 based on 1951 2005 Climax neutron-monitor observations projected forward using a 10.5 year solar cycle and the projected intensity for 1996 thru late 1997 based on scaling the Fe intensity versus Climax data from 1998 2005. During mid-2007 the Fe intensity was only slightly greater than the maximum in 1997-1998 (which was comparable to 1976 solar-minimum cosmic-ray levels measured by IMP-8). Although the projection suggested that the intensity would begin to decrease after 2007 with the expected onset of solar activity, instead, solar-minimum conditions have continued, and there was actually an increase in the GCR intensity early in 2008. From October 2008 thru March 2009 the 6-month average intensity was 12% ± 1% above the maximum reached in 1997-1998.

The GCR increase in 2008 is likely related to a drop in the tilt of the heliospheric current sheet (HCS) in early 2008 (bottom panel). During 2006-2007 the tilt was ~30° - 40°, considerably greater than during the 3 previous solar minima, when it reached <20°.>

These recent GCR data are important to the Human Exploration program since they demonstrate that not all solar minima are the same, and that radiation levels in interplanetary space can exceed those experienced earlier in the space era (as is also indicated by measurements of Be-10 in ice cores deposited over the last few centuries).

NASA Names 16th Annual Great Moonbuggy Race Winners

Apr 27, 11:44 am

MTSU students took home the NASA Safety Systems Award at this month’s Great Moonbuggy Race held at the U.S. Space and Rocket Center in Huntsville, Ala.

HUNTSVILLE, Ala. — NASA this weekend named its “off-world racing” champions in the 16th annual Great Moonbuggy Race: Rochester Institute of Technology in Rochester, N.Y. won the college division; and Erie High School Team 2 from Erie, Kan., and Huntsville Center for Technology Team 2 from Huntsville, Ala., tied for first place in the high school division.

The three teams bested a field of competitors that included 68 teams from 20 states, Puerto Rico, Canada, Germany, India and Romania.

Rochester Institute and Huntsville Center for Technology were the 2007 college and high school champions, respectively. Erie High School edged out all competitors and won its division in 2008.

NASA’s Great Moonbuggy, held April 3-4 at the U.S. Space & Rocket Center in Huntsville, Ala., challenges students to think like NASA engineers as they design, build and race lightweight, human-powered buggies — inspiration, perhaps, to help NASA continue its exploration mission in coming decades.

The winning teams posted the fastest vehicle assembly and race times in their divisions and received the fewest on-course penalties. The winning Erie High School and Huntsville Center for Technology teams finished the roughly half-mile course — twisting curves, treacherous gravel pits and other obstacles simulating lunar surface conditions — in just 3 minutes 25 seconds. The team from Rochester Institute of Technology posted a time of 3 minutes 30 seconds.

Finishing in the second and third slots this year in the high school division were Arab High School in Arab, Ala., and Huntsville Center for Technology Team 1, respectively. The University of Puerto Rico in Humacao won second place in the college division; and the University of Wyoming in Laramie, Wyo., took home third place despite flipping their buggy late in the winning run.

Race organizers at NASA’s Marshall Space Flight Center in Huntsville presented first-place winners in each division with a trophy depicting NASA’s original lunar rover. NASA also gave plaques and certificates to every team that came to Huntsville to race.

The first-place high school team also received $500 and a week at Spacecamp, courtesy of race sponsors ATK Launch Systems of Huntsville. ATK awarded the second- and third-place high school teams $250 each. Race sponsor Lockheed Martin of Huntsville also presented the winning college team with $5,700 in cash.

Individuals on all three winning teams also received commemorative medals and other prizes. For a complete list of additional awards for design, safety, innovation and spirit, see below.

NASA’s Great Moonbuggy Race is inspired by the original lunar rover designed by engineers at the Marshall Center. Apollo 15 astronauts David Scott and Jim Irwin piloted the first rover across the moon’s surface in July 1971. The moonbuggy continued to chart new lunar territory during the Apollo 16 and Apollo 17 missions.

Today, student racers face design challenges similar to those overcome by Apollo-era rover engineers. Teams build their vehicles from the ground up, typically using bicycle or light motorcycle tires, aluminum or composite-metal struts and parts, and the best drive trains, gears, suspension, steering and braking systems they can find or devise.

That’s a key goal of the Great Moonbuggy Race: to inspire students to solve the kinds of problems NASA workers face every day as they seek to continue the nation’s exploration of space, benefit life on Earth and gain new understanding of our place in the cosmos.

“This year’s race proved once again that offering students a unique challenge, such as building their own moonbuggy, can inspire and engage them — turning an engineering project into the best fun you can have on wheels,” said Tammy Rowan, manager of the Marshall Center’s Academic Affairs Office, which organizes the moonbuggy race each year.

“We’re excited that more than a quarter of our participants this year were teams and schools new to the race,” Rowan added. “It’s great to see more and more young people exploring potential careers in science, technology, engineering and mathematics — the cornerstones of the nation’s economic might.”

The first Great Moonbuggy Race in 1994, commemorating the 25th anniversary of the Apollo 11 lunar landing, was open only to college teams. Eight teams participated. Two years later the event was expanded to include high school teams.

NASA’s Great Moonbuggy Race is one of dozens of educational programs and initiatives led by the Marshall Center each year to help attract and inspire America’s next generation of scientists, engineers and explorers — those who will carry on the nation’s mission of exploration, to the moon and onward into the solar system.

The race is hosted by the U.S. Space & Rocket Center, and sponsored by NASA’s Space Operations Mission Directorate in Washington. Major corporate sponsorship is provided by Lockheed Martin, The Boeing Company, Northrop Grumman Corp., Teledyne Brown Engineering and Jacobs Engineering Science Technical Service Group, all of Huntsville.
