NASA's Twin Grail Spacecraft Reunite in Lunar Orbit

The full version of this story with accompanying images is at:
http://www.jpl.nasa.gov/news/news.cfm?release=2012-001&cid=release_2012-001

PASADENA, Calif. -- The second of NASA’s two Gravity Recovery And Interior Laboratory (GRAIL) spacecraft has successfully completed its planned main engine burn and is now in lunar orbit. Working together, GRAIL-A and GRAIL-B will study the moon as never before.

"NASA greets the new year with a new mission of exploration," said NASA Administrator Charles Bolden. "The twin GRAIL spacecraft will vastly expand our knowledge of our moon and the evolution of our own planet. We begin this year reminding people around the world that NASA does big, bold things in order to reach for new heights and reveal the unknown."

GRAIL-B achieved lunar orbit at 2:43 p.m. PST (5:43 p.m. EST) today. GRAIL-A successfully completed its burn yesterday at 2 p.m. PST (5 p.m. EST). The insertion maneuvers placed the spacecraft into a near-polar, elliptical orbit with an orbital period of approximately 11.5 hours. Over the coming weeks, the GRAIL team will execute a series of burns with each spacecraft to reduce their orbital period to just under two hours. At the start of the science phase in March 2012, the two GRAILs will be in a near-polar, near-circular orbit with an altitude of about 34 miles (55 kilometers).

During GRAIL's science mission, the two spacecraft will transmit radio signals precisely defining the distance between them. As they fly over areas of greater and lesser gravity caused by visible features such as mountains and craters, and masses hidden beneath the lunar surface, the distance between the two spacecraft will change slightly.

Scientists will translate this information into a high-resolution map of the moon's gravitational field. The data will allow scientists to understand what goes on below the lunar surface. This information will increase knowledge of how Earth and its rocky neighbors in the inner solar system developed into the diverse worlds we see today.

Each spacecraft carries a small camera called GRAIL MoonKAM (Moon Knowledge Acquired by Middle school students) with the sole purpose of education and public outreach. The MoonKAM program is led by Sally Ride, America's first woman in space, and her team at Sally Ride Science in collaboration with undergraduate students at the University of California in San Diego.

GRAIL MoonKAM will engage middle schools across the country in the GRAIL mission and lunar exploration. Thousands of fifth- to eighth-grade students will select target areas on the lunar surface and send requests to the GRAIL MoonKAM Mission Operations Center in San Diego. Photos of the target areas will be sent back by the GRAIL satellites for students to study.

A student contest that began in October 2011 also will choose new names for the spacecraft. The new names are scheduled to be announced in January 2012. Ride and Maria Zuber, the mission's principal investigator at the Massachusetts Institute of Technology in Cambridge, chaired the final round of judging.

NASA's Jet Propulsion Laboratory in Pasadena, Calif., manages the GRAIL mission for NASA’s Science Mission Directorate, Washington. The GRAIL mission is part of the Discovery Program managed at NASA's Marshall Space Flight Center in Huntsville, Ala. Lockheed Martin Space Systems in Denver built the spacecraft. JPL is a division of the Çalifornia Institute of Technology in Pasadena.

Good choices. For some odd reason I'm thinking Starsky & Hutch :P

Let's hope the mirror image satellites enjoy a harmonious relationship.  If they don't, Lokai and Bele, of Star Trek fame will be appropriate.

But, I suppose that would be too 'dark' for NASA.

The Grail page at Eyes on the Solar System:

http://solarsystem.nasa.gov/eyes/player/index.html?document=$SERVERURL/content/documents/grail/v1.0/grail.xml

is indicating that the apoapsis of Grail A's orbit has been lowered by more than a thousand miles.  Can anyone confirm this?

New Year's Day, respectively. The status of the spacecraft and
upcoming plans for science operations also will be discussed.

NASA Television and the agency's website will broadcast the live
event. Journalists can participate from NASA centers or join by
phone. To obtain dial-in information, media representatives must
contact Steve Cole at [email protected], by noon EST, Tuesday,
Jan. 17.

The participants are:

-- John Grunsfeld, associate administrator, Science Mission
Directorate, NASA Headquarters, Washington
-- Leland Melvin, associate administrator for Education, NASA
Headquarters
-- Maria Zuber, GRAIL principal investigator, Massachusetts Institute
of Technology, Cambridge, Mass.
-- Sally Ride, president and CEO, Sally Ride Science, San Diego
-- Teacher and students submitting the selected names

There was no NASA TV coverage when the Grail Spacecraft went into orbit.  The only news came from the JPL twitter feed.  It makes you wonder who is making the decisions at NASA.

Presser from NASA:

RELEASE: 12-019

MONTANA STUDENTS SUBMIT WINNING NAMES FOR NASA LUNAR SPACECRAFT

WASHINGTON -- Twin NASA spacecraft that achieved orbit around the moon
New Year's Eve and New Year's Day have new names thanks to elementary
students in Bozeman, Montana. Their winning entry, "Ebb and Flow,"
was selected as part of a nation-wide school contest that began in
October 2011.

The names were submitted by fourth graders from the Emily Dickinson
Elementary School. Nearly 900 classrooms with more than 11,000
students from 45 states, Puerto Rico and the District of Columbia,
participated in the contest. Previously named Gravity Recovery And
Interior Laboratory, or GRAIL A and B, the washing machine-sized
spacecraft begin science operations in March.

"The 28 students of Nina DiMauro's class at the Emily Dickinson
Elementary School have really hit the nail on the head," said Maria
Zuber, GRAIL principal investigator from the Massachusetts Institute
of Technology. "We were really impressed that the students drew their
inspiration by researching GRAIL and its goal of measuring gravity.
Ebb and Flow truly capture the spirit and excitement of our mission."

Zuber and Sally Ride, America's first woman in space and CEO of Sally
Ride Science in San Diego, selected the names following the contest,
which attracted 890 proposals via the Internet and mail. The contest
invited ideas from students ages 5 to 18 enrolled in U.S. schools.
Although everything from spelling and grammar to creativity were
considered, Zuber and Ride primarily took into account the quality of
submitted essays.

"With submissions from all over the United States and even some from
abroad, there were a lot of great entries to review," Ride said.
"This contest generated a great deal of excitement in classrooms
across America, and along with it an opportunity to use that
excitement to teach science."

GRAIL is NASA's first planetary mission carrying instruments fully
dedicated to education and public outreach. Each spacecraft carries a
small camera called GRAIL MoonKAM (Moon Knowledge Acquired by Middle
school students). Thousands of students in grades five through eight
will select target areas on the lunar surface and send requests for
study to the GRAIL MoonKAM Mission Operations Center in San Diego.

The winning prize for the Dickinson students is to choose the first
camera images. Dickinson is one of nearly 2,000 schools registered
for the MoonKAM program, which is led by Ride and her team at Sally
Ride Science in collaboration with undergraduate students at the
University of California in San Diego.

"These spacecraft represent not only great science but great
inspiration for our future," said Jim Green, director of NASA's
Planetary Science Division in Washington. "As they study our lunar
neighbor, Ebb and Flow will undergo nearly the same motion as the
tides we feel here on Earth."

Launched in September 2011, Ebb and Flow will be placed in a
near-polar, near-circular orbit with an altitude of about 34 miles
(55 kilometers). During their science mission, the duo will answer
longstanding questions about the moon and give scientists a better
understanding of how Earth and other rocky planets in the solar
system formed.

NASA's Jet Propulsion Laboratory in Pasadena, Calif., manages the
GRAIL mission for NASA's Science Mission Directorate in Washington.
The GRAIL mission is part of the Discovery Program managed at NASA's
Marshall Space Flight Center in Huntsville, Ala. Lockheed Martin
Space Systems in Denver built the spacecraft.

Kudos to NASA/JPL/Sally Ride for getting the kids involved with MoonKAM!
