Astronomers See gravity Wobbles from Exosolar Planets.
What goes up must come down, and if you're an Apollo astronaut, hopefully,
what lands will take off again, so you can go home. Floyd Bennett the
guest on SpaceWatch.com's weekly live Internet TV show, "Mission Control,
Over" made sure of it. As Chief of NASA's Lunar Landing Analysis Branch,
he selected lunar landing sites, designed touchdown trajectories, and
oversaw the Apollo 11-17 descents and ascents from the control room.
In gratitude, the Apollo 15 astronauts named a Moon mountain near
their landing site after him.

ASTRONOMERS SEE gravity WOBBLES FROM EXOSOLAR PLANETS
Although the star system Upsilon Andromedae was discovered to have
multiple planets in the spring of 1999, Astronomers have been able to
observe the star actually wobble back and forth in the sky because of
the gravitational effect of the planets. This has allowed the team to
calculate the mass of the planets with a high degree of accuracy - the
largest has 10 Jupiter masses.
CHANDRA IMAGES CRAB NEBULA PULSAR
The Chandra X-ray observatory continues to impress with its latest images
taken of the Crab Nebula - a supernova remnant. The image shows brilliant
ring around a pulsar at the nebula's center, and provides Astronomers with
more information about how a pulsar reacts with the nebula around it.
PIONEER 10 MAKES A NEW DISCOVERY
Even after it's left the solar system, Pioneer 10 is still continuing
to provide Astronomers with valuable research. Researchers have calculated
that an object's gravity changed the spacecraft's trajectory for 25
days - they're still working on calculating the upper limits of its mass.
Pioneer 10 was launched in 1972, and is currently 11 billion kms
from the Earth.
PANELS INVESTIGATE ORBITER ACCIDENT
NASA has formed three panels to investigate the loss of the Mars
Climate Orbiter, after it disappeared early Thursday. The panels
will consist of a review board appointed by NASA managers; a peer
review board to investigate the technical failure; and an independent
review panel. The Space probe cost $125 million.
