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.
