The Columbia inquiry is far from its final conclusion, but many questions have arisen about the safety of the Space Shuttle system. Even if the cause of the fatal accident is found directly in the Shuttle spacecraft itself, the root of its problem could be in the Shuttle's basic design philosophy which has a primary influence on safety and performance. This article discusses the main problems with the Shuttle's design and considers what alternatives were possible during the main system design. |

Researchers Achieve Quantum Entanglement Of Three Electrons
Ann Arbor - Mar 03, 2003The quantum entanglement of three electrons, using an ultrafast optical pulse and a quantum well of a magnetic semiconductor material, has been demonstrated in a laboratory at the University of Michigan, marking another step toward the realization of a practical quantum computer. ILS Postpones Hellas-Sat Launch 
Cape Canaveral - Mar 03, 2003The scheduled March 14 launch of the Hellas-Sat satellite on an Atlas V vehicle has been postponed, International Launch Services (ILS) announced today. |
Optical Trap Provides New Insights Into Motor Molecules
Stanford - Mar 03, 2003Of special interest to nanoengineers is the naturally occurring protein kinesin - one of several "motor molecules" that facilitate movement in living cells. Ariane 5 To Launch Space Tugs For Orbital Recovery Corp 
Paris - Mar 3, 2003Orbital Recovery Corporation has selected Ariane 5 as the primary launch vehicle for its Geosynch Spacecraft Life Extension System (SLESTM), signing an agreement with Arianespace to orbit at least four SLES space tugs beginning in 2005. |
Cassini Finds Massive Gas Cloud Surrounding Jupiter 
Laurel - Mar 3, 2003Using a sensitive new imaging instrument on NASA's Cassini spacecraft, researchers have discovered a large and surprisingly dense gas cloud, sharing an orbit with Jupiter's icy moon Europa. Galileo's Final Months 
Pasadena - Mar 03, 2003As usual for the combination of an aging spacecraft and an intensely energetic environment, Jupiter dealt Galileo a temporarily crippling blow during our flyby of Amalthea on Tuesday, November 5, 2002. |
ESA Takes It On The Chin As Euronauts Grounded
Paris - Mar 03, 2003The European Space Agency (ESA) has agreed to six-month postponements of the Soyuz flights by two members of its astronaut corps planned for April and October 2003. Why We Fly 
Scottsdale - Feb 26, 2003Post-Columbia punditry has formed up into two camps: mystically pro-human and reductionistically pro-robot. Before the isolated sparring turns into a general melee, we should look up from our conflicting means to examine the question of ends. If any of us are to be effective, in water-cooler conversation, op-ed high-noon showdowns or Congressional testimony, we'll need a good firm grip on our own answer to the root question: why do we want to go to space?, asks John Carter McKnight. |
Researchers Conduct Most Sensitive Search For New Forces
Boulder - Mar 03, 2003Researchers have conducted the most sensitive search to date for gravitational-strength forces between masses separated by only twice the diameter of a human hair, but they have observed no new forces. Are There Earth-Like Planets Near Other Stars 
Heidelberg - Mar 03, 2003The Max Planck Institute for Astronomy in Heidelberg has organized the first international conference with the emphasis on the space missions "DARWIN" and "Terrestrial Planet Finder" Many Applications Possible For Largest Quantum Infrared Detector 
Greenbelt - Mar 3, 2003The world's first one million-pixel Quantum Well Infrared Photodetector array has been fabricated and tested by a NASA-led team. The new detector promises to be a low-cost alternative to conventional infrared detector technology for a wide range of applications. |
Columbia Investigation Gathers Pace San Francisco - Feb 27, 2003 
Evidence is growing that NASA became alarmingly sloppy about the possible danger posed by detached fragments of the external tank's insulation hitting the Shuttle's tiles - in the same way NASA got sloppy about the threat posed by O-ring erosion due to cold weather before Challenger. |
