			  MONDAY MAY 27, 1991


SpaceNews originates at KD2BD in Wall Township, New Jersey, USA.  It
is published every week and is made available for unlimited distribution.



* NOAA-12 NEWS *
================
NOAA-12 is currently transmitting APT images on a frequency of 137.50 MHz,
the same as NOAA-10, with AOS about 45 minutes later.  Several satellite
users have noted that so far, NOAA-12 was transmitting visible light
images only, without any infrared images.  Reports received so far indicate
the spacecraft is transmitting high-quality images.


* MIR NEWS *
============
The Soviet/British Juno flight on Soyuz TM-12 successfully docked with
the Mir space station on 20-May-91 at about 17:25 Moscow Time (9:25
EDT).  On board were cosmonauts Anatoli Artsebarski and Sergei Krikalev,
plus Helen Sharman, the first British astronaut.  This mission was delayed
from its original launch date of May 12th.  They were greeted by
Viktor Afanasyev and Musa Manarov, who were launched on Soyuz TM-11 on
02-Dec-90.  Afanasyev and Manarov will be brought Sharman down on May 26th.
Artsebarski and Krikalev will be staying on board Mir for the next 6 months.
They will be doing several space walks, including one to repair the antenna
damage that caused the Progress M-7 to have problems docking at the
March 19th attempt.   In addition, Radio Moscow stated the two would be
installing a new solar panel set to be delivered by their space shuttle.

* ASTRO MISSION TO REFLY *
==========================
NASA announced that a second Astro mission will fly aboard the Space
Shuttle.  The success of the earlier mission and the demonstrated
ability of the instruments to acquire high-quality scientific data are
among the major reasons for reflight of the Astro payload.

Astro-2, like Astro-1 which flew in December of 1990 aboard Space
Shuttle Columbia, will be dedicated to a single scientific discipline -
astrophysics.  The following three instruments will fly on Astro-2 and
observe energetic objects in space in the ultraviolet portion of the
electromagnetic spectrum:

  The Hopkins Ultraviolet Telescope  (HUT), developed at Johns Hopkins
  University, performs spectroscopy, breaking light into its constituent
  colors, allowing scientists to analyze the chemical composition and
  temperature of the objects HUT observes.

  The Ultraviolet Imaging Telescope (UIT), developed by NASA's Goddard
  Space Flight Center, produces images of especially hot components of
  nebulae, stars and galaxies. These images help to explain the physical
  structure of such objects.

  The Wisconsin Ultraviolet Photopolarimeter Experiment (WUPPE),
  developed at the University of Wisconsin, measures a subtle
  characteristic of light, its polarization.  These measurements probe
  the orientation and detailed physics of the distant regions in which
  the light originates.

During the Astro-1 mission, new results were obtained at wavelengths
observable only from space.  Astronomers gained insights into the
properties of diffuse dust found between stars as well as details of
the formation of new stars in distant galaxies.  They also learned that
the predicted decay of certain sub-atomic interstellar particles did
not occur, at least not at the expected level.
