and send several telecasts from
space - including a news con-
ference and an orbital tour of
Russia with commentary by
Kubasov in English.
All five astronauts and cosmo-
nauts have trained extensively
for every aspect of the joint ac-
tivities - which, when they fi-
nally reach space, may seem
like just another simulation to
them.
The last of the joint experi-
ments is one that can be per-
formed only with two space-
craft and is ideal for ASTP.
Shortly after the two ships sep-
arate, on the morning of July
19, Apollo will maneuver into a
position blocking the sun from
the view of Soyuz, in effect,
creating a solar eclipse.
THIS ALLOWS the Soyuz cos-
monauts a perfect opportunity
to take photographs of the solar
corona - the thin circle of light
surrounding the sun's disk -
which is invisible to earth-bound
astronomers. The pictures re-
turned from this experiment
may be the best corona shots
ever acquired.
After the artificial eclipse,
Apollo and Soyuz will go their
separate ways. Leonov and Ku-
basov plan to remain in orbit for
about two days, conducting a
few experiments on their own,
then return to earth near Bai-
konur (unlike American space-
craft, manned Soviet missions
always return with a soft land-
ing on solid ground, instead of
the ocean. The descent is slowed
by a single parachute and retro-
rockets.)

pace d
Stafford, Slayton and Brand,
on the other hand, have a more
ambitious schedule and will stay
up for five days after separa-
tion. Many of their experiments
are follow-ups to projects in the
1973-74 Skylab series.
FOR EXAMPLE, one Apollo
experiment will investigate the
advantages of zero-gravity man-
ufacturing. Scientists believe
that the crystals used in elec-
tronic devices can be made
more perfect under weightless
conditions, and that such crys-
tals will greatly advance the
technology associated with in-
tegrated circuits.
Finally, on July 24, the astro-
nauts will eject the Service Mod-
ule portion of the Apollo space-
craft and return to the Pacific
Ocean in what may be the last
American "splashdown" ever -
the next breed of spacecraft, the
Space Shuttle, will land like an
airplane, on wheels.
Critics of the space program,
who usually focus upon the econ-
omic aspects of space flight,
have latched onto a few other
factors of the $254 million ASTP
mission in their protest. Chief
among them is Senator William
Proxmire (D-Wis.), who fears
for the astronauts' safety in
light of past Soyuz re-entry fa-
talities and docking problems.
Proxmire claims the Central
Intelligence Agency has deter-
mined that the Soviet Union can-
not handle two of their own
spacecraft at once. Soyuz 18,
carrying two cosmonauts, was
launched into orbit in late May
and will reportedly remain
there throughout the joint mis-
sion next week.

etente
THE SOVIETS, however, say
two simultaneous flights will not
overburden their facilities be-
cause the vehicles will be
handled from separate control
centers. In an emergency, the
Russians add, the spacecraft
linked with Apollo will get their
"priority" attention.
American officials stress that
the flight is much more than "a
handshake in the sky," and jus-
tify ASTP by its purely scientific
experiments, numbering more
than 20.
The greatest benefits of ASTP,
in fact, may come long after
either vehicle returns to earth.
Space officials in the United
States, faced with ever-tighten-
ing budgets as the public loses
interest in NASA activities, hope
the project will lead to joint ef-
forts in long-term space sta-
tions or, conceivably, an Amer-
ican-Soviet flight to Mars near
the end of the century.
WHATEVER its results, ASTP
has already served as a sym-
bolic end to the fast-paced, ex-
pensive "space race" which be-
gan with a Sputnik satellite in
1957. Both countries seem eager
to explore for the sake of sci-
ence now, and they may well
end up doing it together.

Broadway's BARBARA COOK & THE FESTIVAL CHORUS
Wednesday, July 16, in Hill Auditorium, 8:30
Long a star of the Broadway musical-theater scene, Miss Cook recently made her solo debut in New
York's Carnegie Hall to rave reviews. For her Ann Arbor concert debut next week, she'll sing se-
lections from Broadway musicals and is featured with our Festival Chorus in excerpts from "Candide"
by Leonard Bernstein, and "The King and I" by Richard Rodgers. Under Donald Bryant's direction,
the Chorus of 100 singers presents a group of four American folk songs and four Negro spirituals,
in special arrangements by Mr. Bryant.
