COMMENTS FROM RON BROWNING, GRAA PRESIDENT: Our March speaker was Dr. Paul Newman, Goodard’s Chief Scientist for Atmospheric Sciences, who explained what brought about the Montreal Protocol (MP), which banned chlorofluorocarbons (CFCs). NASA Goddard’s Solar Background Ultraviolet/Total Ozone Mapping Spectrometer (SBUV/TOMS) instrument starting with Nimbus-4 in 1974 has been measuring ozone above the stratosphere. The TOMS measurements have monitored global ozone, including verifying deteriorating ozone over Antarctica, since then. These and other data brought about an international agreement to ban all substances that deplete ozone. A major source was CFCs which were banned worldwide in 1981, which resulted in no more Freon in air conditioners and refrigeration as well as a ban on aerosol sprays. He showed charts of global ozone over the last 34 years since the MP was implemented. There continues to be the hole over Antarctica, but there has been a positive ozone increase. Nimbus-4 and -7 have made dramatic impacts on public and science perception of the ozone hole. If the MP had not been signed, it is projected that two-thirds of ozone would have been depleted by 2065 and lack of ultraviolet protection that it provides could result in the Earth becoming unlivable. Since 2000 there has been a positive increase in ozone, but recovery is slow and the hole over Antarctica still exists.

TREASURER’S REPORT: Treasurer Jackie Gasch received tax-deductible contributions from the following: Paul Karpiscak, David R. Manges, Charles M. MacKenzie, Raymond W. Melcher, Edward Radovich, and Robert C. Wigand.

FROM THE GODDARD ARCHIVES – IT HAPPENED IN APRIL: On April 24, 1990, Space Shuttle Discovery (STS-31) lifted off from Kennedy Space Center and successfully deployed the Hubble Space Telescope. This month marks the 25th Anniversary of this most incredible and awe-inspiring spacecraft. Congratulations to the NASA Goddard family for a truly outstanding adventure through the heavens.

UPDATE ON THE MAGNETOSPHERIC MULTISCALE (MMS) MISSION: The MMS mission successfully launched from Cape Canaveral Air Force Base, FL, on March 12th on an Atlas V421 rocket. The MMS spacecraft are positioned in Earth’s orbit to begin the first space mission dedicated to the study of a phenomenon known as magnetic reconnection. This process is thought to be the catalyst for some of the most powerful explosions in our solar system. The four spacecraft of the constellation were positioned one on top of the other and, after reaching orbit, each was deployed from the rocket’s upper stage sequentially in five-minute intervals. Craig Tooley, MMS Project Manager, said on behalf of the entire MMS team that “we’re thrilled to see all four of our spacecraft have deployed and data indicates we have a healthy fleet.” Over the next several weeks NASA scientists and engineers will deploy booms and antennas on the spacecraft and test all instruments. The observatories will later be placed into a pyramid formation in preparation for science observations which are expected to begin in early September. Goddard built, integrated and tested the four MMS spacecraft and is responsible for overall mission management and operations.

53rd ROBERT H. GODDARD MEMORIAL SYMPOSIUM: The 53rd Robert H. Goddard Memorial Symposium, hosted by the American Astronautical Society (AAS) was held March 10th – 12th at the Greenbelt Marriott. This year’s theme, “On the Cusp: What’s Next,” resulted in discussions that were more upbeat and positive than in recent years. Results from recent science missions, ongoing new missions and real hardware test results from the James Webb Space Telescope mirror and instruments, the new Orion exploration spacecraft and Space Launch System, and the successful launch of the MMS four-satellite constellation were definitely reasons for optimism. In addition, there are many exciting projects in commercial space ventures on the horizon. To view the entire symposium’s presentations and videos, check out the AAS website at http://www.astronautical.org.

A BIT OF SPACE HISTORY ABOUT OUR COMPETITOR: 50 years ago, on March 18, 1965, Soviet/Russian Cosmonaut Alexei Leonov became the first human to conduct extra-vehicular activity, exiting the capsule during the Voskhod 2 mission for a 12-minute spacewalk. In 1959, the then 25-year-old and now retired Major General Leonov was selected as one of the first 20 cosmonauts.

THOUGHT FOR APRIL: People who get too big for their britches undoubtedly become totally exposed in the end.

REMEMBERING OUR FORMER COLLEAGUES:

CHANGES TO GODDARD’S LEADERSHIP TEAM: With the retirement of Deputy Center Director Arthur (Rick) Obenschain at the end of March after his dedicated service of 50+ years, George Morrow (current Director of the Flight Projects Directorate) assumed the Deputy Center Director position. At the same time, Dr. Colleen Hartman became Director of the Sciences and Exploration Directorate and David Mitchell became Director of the Flight Projects Directorate. We say a fond farewell to Rick and welcome Colleen and Dave to their new leadership roles.

PLEASE KEEP GRAA IN THE LOOP WHEN YOU MOVE: In the March issue, members were encouraged to kindly notify GRAA when you move permanently to a new address. Not only does it make it easier to keep our membership database up-to-date, but it also saves GRAA money, as every time newsletters bounce back from the postal service as being undeliverable, GRAA is charged more than three times as much as it costs to initially send them out. In December we had 30+ newsletters returned by the postal service because members moved without letting us know. Your local post office can provide you with change of address forms and GRAA will be much better off for you sending one to us.
