Shop Center r
State Rep. George W. Sallade
(R-Ann Arbor) has given his sup-
port to a move to block construc-
tion of a shopping center in south-
east Ann Arbor.
Sallade sent letters Friday to
Councilmen Florence R. Crane and
Clan Crawford, Jr., of the Second
Ward, in whose district the shop-
ping center would lie, supporting a
change in zoning which would halt
the shopping center plans.
Sallade served as president of
City Council in 1954, when zoning
in the area was changed from
"multiple dwelling" to "local busi-
ness." He now supports the drive
to change the zoning ordinance,
stating in his letter that "School
housing and parochial building de-
velopments in this district have
considerably altered the neighbor-

Prof. Leo Goldberg, chairman of
the department of astronomy, said.
Russia "obviously was going all
out" on the project.
"We (the United States) haven't
been running scared," he said. "All
the technical data was' at hand
and it was simply a question of
which nation would make the' big-
gest effort to do it first."
Prof. Goldberg also expressed
surprise at the size of the reported
weight of the satellite. "We've been
talking about a 20 or 30 pound
object," he said.
Nelson Spencer, research engi-
neer in the Engineering, Research
Institute, said the satellite launch-
ing indicated Russia probably has
the knowledge to support its claims
of possessing an intercontinental
ballistic missile. He added that the

lines of an ICBM."
Jones said that until the Rus-
sians revealed further information,
there was no way of telling whe-
ther a sphere was launched by a
three-stage rocket or a single'stage
ICBM which "certainly would be
capable of doing the job."
Both Spencer and Jones are
members of the Rocket andSatel-

States, a gr6up of American scien-
tists which has been engaged in
rocket research since 1946 and
more recently, in satellite research.

But the problem of launching a
satellite, he said, is much greater
than just shooting a rocket high
into the sky..
"Once the rocket has reached
the 'desired height, it must then
give a tremendous thrust to the
satellite to get it moving in "its
orbit and' this thrust must be given
at just the right moment and
angle," he explained.
