involved in many development projects, e.g.
realizing a next-generation drop tower system
called GraviTower Bremen.
Dr. Könemann started his academic career
reading physics in Hanover, Germany. After
his intermediate diploma he changed to the
University of Bremen and first came in contact
with ZARM as a student. During his student
time at ZARM he was involved in the
MICROSCOPE project for a short period. In
2006 he finished his diploma thesis in the field
of quantum physics and immediately
proceeded to work as a PhD student in the
same project at ZARM. Within this pilot
project called QUANTUS Dr. Könemann was
a member of the team that realized the world’s
first Bose-Einstein Condensate under
weightlessness conditions at the Drop Tower
Bremen. Up to now, the QUANTUS project
and its follow-on projects represent an
emerging area of science in quantum
engineering with an impressive potential for
future technology developments and
multidisciplinary applications. In many
proceedings and publications including one
remarkable publication in Science Magazine -
Science 328, 1540 (2010) - related to this topic
Dr. Könemann made significant contributions
as author as well as co-author.
After finishing his PhD with a doctoral degree
in engineering Dr. Könemann directly moved
to ZARM FAB mbH early 2010. Since then, he
has facilitated and managed a large number of
microgravity experiments at the Drop Tower
Bremen within a variety of research fields, e.g.
Astrophysics, Biology, Combustion, Fluid
Dynamics, Fundamental Physics and Materials
Sciences.
In Memoria
Robert P. Lin (1942-2012),
COSPAR Vice-President and
Pioneering Space Scientist
Robert Lin, vice-president of COSPAR and
pioneer in the field of high-energy space
physics, collapsed after suffering a stroke in
his laboratory at the University of California,
Berkley on 16 November 2012. He died, with
his wife at his side, the following day.
On hearing this sad news, COSPAR Executive
Director Jean-Louis Fellous commented: “His
passing away is and will be felt as a great loss
within our space research community. Bob
Lin’s memory will remain with us as an
example of wisdom and dedication to science
and international cooperation.” Bob Lin
succeeded Edward C. Stone as U.S.
Representative to COSPAR on 1 July 2010
and, a few weeks later, was elected to one of
COSPAR’s dual vice-presidencies at the 38th
Scientific Assembly in Bremen.
Robert Peichung Lin was born in Kwangsi, in
southern China, on 24 January 1942. He left
China with his parents at a young age and,
after a brief sojourn in London, England,
eventually moved to the United States and
settled in Michigan.
He completed his undergraduate studies in
physics at the California Institute of
Technology in 1962. For his graduate studies,
he moved on to the Department of Physics at
the University of California, Berkeley.

At Berkeley, Bob became a protégé of
pioneering space physicist Kinsey Anderson.
The latter was the principal investigator of the
Ion Chamber and G.-M. Counters experiment
on NASA’s Interplanetary Monitoring Platform
3 (IMP 3, also known as Explorer 28). The
directions of Bob’s graduate studies and a
primary focus of his future research career
became apparent in 1966 when he and
Anderson reported that high-energy electrons
detected by IMP 3 were associated with a solar
flare. This discovery lead to the publication of
Bob’s first two scientific papers: “Observations
on the Propagation of Solar Flare Electrons in
Interplanetary Space” in Physical Review
Letters and “Evidence for Connection of
Geomagnetic Tail Lines to the Interplanetary
Field” in the Journal of Geophysical Research.
Both papers were co-authored with Anderson.
The discovery also formed the basis of Bob’s
1967 doctoral dissertation, Observations of
Solar Flare Electrons in Interplanetary Space.
After receiving his doctorate, Bob maintained
his association with Berkley and, in particular,
the university’s Space Sciences Laboratory
(SSL) for the rest of his career. Over the next
30 years he ascended through the ranks of the
SSL hierarchy from assistant research physicist
(1967) to associate director (1992). In 1998, he
became director of the SSL and retained the
directorship until his retirement in 2008. In
addition to his various positions at the SSL,
Bob also held professorships in Berkeley’s
physics and astronomy departments.
Bob’s research topics were diverse. He defied
easy categorization into one of the traditional
space science disciplines. His interests
included supernovae, solar flares, the magnetic
fields on the surface of the Moon and Mars,
and the geospace environment. Thus, his
interests encompassed astrophysics, solar
physics, planetary science, and space physics.
However, a common theme linking most of his
research activities was that of how particles are
accelerated to high energies in cosmic
environments.
At the height of his career, he wrote: “My
research interests are in the areas of
experimental space physics and high-energy
astrophysics. Specific topics in space physics
include solar flares and solar cosmic rays;
plasma phenomena in the interplanetary
medium and the Earth’s magnetosphere such as
collisionless shock waves, particle
acceleration, magnetic reconnection, and
wave-particle interactions; and lunar, planetary,
and cometary studies. In high-energy
astrophysics, I have concentrated on high
resolution gamma-ray and hard X-ray
spectroscopy and imaging of line and
continuum emissions from the Sun, cosmic
sources, and the Earth. These emissions
provide detailed information on processes such
as the interaction of accelerated particles with
matter, radioactive decay of newly formed
isotopes in supernovae, positron annihilation
near black holes, cyclotron emission in the
strong magnetic fields of neutron stars, etc. My
approach is to develop innovative instruments
and fly them on spacecraft, rockets, and
balloons.”
During his long association with the SSL, Bob
was actively involved with numerous
spacecraft missions including: IMP 4, 5, and
27
6; Explorer 33 and 35; the lunar subsatellites
deployed by Apollo 15 and 16; International
Sun-Earth Explorer 1, 2, and 3; Wind, the
Solar TErrestrial Relations Observatory
(STEREO) and the Time History of Events and
Macroscale Interactions during Substorms
(THEMIS) missions; Mars Global Surveyor
and Lunar Prospector; and Giotto and Cluster.
Bob’s greatest achievement was probably the
Ramaty High Energy Solar Spectroscopic
Imager (RHESSI), a spacecraft for which he
was the principal investigator. This Small
Explorer mission was launched in 2002 to
explore the basic physical processes
responsible for particle acceleration and the
explosive release of energy during solar flares.
This was achieved through imaging and
spectroscopic observations of bremsstrahlung
hard X-ray/gamma-ray continuum and gamma-
ray lines produced by the energetic electrons
and ions, respectively. RHESSI also made
important astrophysical observations. These
included the detection of the gamma-ray
emission line of the short-lived radionuclide 26
Al created in supernova explosions, strong
polarization in a cosmic gamma-ray burst,
high-resolution, hard X-ray images of the Crab
nebula.
Even after retiring as director of SSL, Bob
remained an active researcher. He was deeply
involved in the development of new spacecraft
and balloon missions at the time of his death.
His innovative modular microsatellite known
as Cubesat for Ions, Neutrals, Electrons, and
MAgnetic fields (CINEMA) was launched on
13 September, 2012.
His new instrument, the Focusing Optics X ray
Solar Imager (FOXSI) was successfully tested
on a balloon flight on 2 November, 2012.
Finally, the Mars Atmosphere and Volatiles
EvolutioN (MAVEN) mission, for which he
served as the deputy principal investigator, is
scheduled to launch later this year.
Bob received many honours and awards during
his long and distinguished career. He was
elected to the National Academy of Sciences of
United States of America in 2006. His election
citation reads: “Lin is a world-renowned
experimentalist in space science. Through
numerous, innovative instruments that have
flown on NASA missions, he has revealed the
behaviour of electrons and ions accelerated by
the Sun, and detected the accompanying X-ray
and gamma-ray emissions.”
He was also a fellow of the American
Academy of Arts and Sciences and the
American Geophysical Union. He was a
recipient of COSPAR-Chinese Academy of
Sciences Jeoujang Jaw Award and the George
Ellery Hale Prize of American Astronomical
Society’s Solar Physics Division. He also
received a Docteur Honoris Causa de
l’Université de Toulouse in France.
Bob Lin is survived by his wife, Lily Lin of
Berkley, California; and his stepson, Linus
Sun, of New York, New York. The SSL is
establishing a graduate scholarship in his
honour.

Jorge Sahade (1915-2012),
Leading Argentinian Astronomer
Academician (in several academies) Professor
(at many universities), Dr. Jorge Sahade was a
man who took many important decisions
during his almost one hundred years of life,
most of them leading to important results. Late
in 2012 he made, as was his trademark, one
last important decision. He decided that he was
finally tired, tired of living one of the most
active lives any person can imagine living. He
turned off the computer that contains his
unfinished memoirs and simply prepared to die
of natural causes, something that occurred on
18 December 2012.
Jorge Sahade was born in 1915 in Alta Gracia,
Province of Córdoba, Argentina. He first
obtained the Degree of Surveyor at the
Universidad de Córdoba in 1937 and then
moved to La Plata to study astronomy, getting
his Doctorate in Astronomy, the third conferred
