DESIGN FLAW DISCOVERED IN POLAR LANDER

Review boards examining the design of the Mars Polar Lander believe

they may have a possible reason why the spacecraft disappeared on

landing back in December. It's possible that jarring during the

re-entry triggered an early shutoff of the lander's engines,

causing it to drop to the surface. The review boards will provide

their official results in mid-March.

FIRST COLOUR PHOTO OF EROS RELEASED

Now in orbit around asteroid Eros for over 4 days, NEAR produced

its first colour photo of the peanut-shaped spacerock. This and

other preliminary photos of Eros have begun to give scientists

valuable insights into the history and formation of asteroids.

Hopefully the mission will provide clues on how best to protect

the Earth from similar spacerocks.

SHUTTLE HAS ENOUGH FUEL TO COMPLETE ITS MISSION

The astronauts on board the Space Shuttle Endeavour received the

news from NASA yesterday that they had enough fuel to complete their

mapping mission. If everything continues to go as planned, the shuttle

will continue mapping through Sunday, stow the equipment on Monday,

and land on Tuesday.

CORONAL EJECTION HEADED FOR EARTH

Solar Astronomers working with the National Oceanic and Atmospheric

Administration (NOAA) announced that a coronal mass ejection (CME)

occurred on the Sun yesterday, throwing up to 2 billion tonnes of

solar material in the direction of Earth - it's scheduled to arrive

Saturday. If the CME does reach the Earth, it's likely to cause

increased Aurorae, and possibly disrupt satellite communications.

HUBBLE SPOTS GAS RING FROM 1987 SUPERNOVA

When supernova 1987a was discovered thirteen years ago in a nearby

galaxy, Astronomers predicted that a gas ring would light up as a

shockwave from the explosion compresses particles expanding from

the dead star. And, right on cue, the Hubble Space Telescope has

detected the first signs that this event is about to occur.

ARIANE 4 PUTS JAPANESE SAT IN ORBIT

After a one-day weather delay, an Ariane 4 rocket took off from

Kourou in French Guiana carrying a Japanese-built Superbird-4

telecommunications satellite. This is the second successful Ariane

launch of the year, and the fourth Superbird launched by Ariane.
