USSR
The Soviets' space program suffered a major setback
Saturday when their largest space booster, the
J-vehicle, failed shortly after lift-off from the
Tyuratam space center.
The four-stage J-vehicle is capable of placing
275,000 pounds in low earth orbit or 75,000 pounds
on a trajectory to the moon. The booster is esti-
mated to have a thrust of 13 to 14 million pounds
at lift-off compared with the 7.5 million pounds
developed by the Saturn V, the largest US booster.
The Saturn V, however, can 'launch heavier payloads
for lunar missions because it uses high-energy
propellants in its upper stages.
There is no known connection between the J-vehicle
launch attempt and the current Soyuz 11-Salyut mis-
sion, although the cosmonauts were instructed to
observe the failure. Soviet ground control told
the cosmonauts to lookout the window for a fire
like a high magnitude star.

LAOS
On 26 June Vang Pao's irregulars occupied the
southern summit of Phou Seu4 the important ridge on
the southwestern edge of the Plaine des Jarres and
a key objective of their current offensive. Fight-
ing has continued around the northwestern end of the
ridge. In addition to the gains at Phou Seu, the ir-
regulars have taken some high ground near Ban Khong
farther to the northwest. On the eastern side of
the Plaine, the government's newly won positions on
Phou Theung have been reinforced by additional irreg-
ular units.
Intercepts indicate that North Vietnamese forces
are making preparations to counter the irregulars'
inroads into areas where Communist supply lines and
storage facilities on the Plaine are threatened.
Elements of two North Vietnamese regiments which
have recently been shifting positions--the 148th and
165th--have received orders to make attacks on the
irregulars at Phou Seu and Phou Theung. A third NVA
regiment--the 866th--is also in the area and could
support a Communist counterattack.
