NASA review leaves projects on launch pad
Article Abstract:
US space agency NASA Administrator Dan Goldin has ordered a review of all spacecraft missions due for launch in 2000. This follows a series of problems, including the loss of two Mars spacecraft in autumn 1999. Missions to be reviewed include the Microwave Anisotropy Probe and the High Energy Solar Spectroscopic Imager. Many mission scientists are concerned that undertaking a major review at this stage, when launch is due very soon, will cause significant disruption to projects with limited funding and tight schedules.

Launch woes ground NASA science spacecraft
Article Abstract:
The scheduled launch of X-Ray Timing Explorer (XTE) astronomy satellite in the last week of Aug 1995 was delayed by NASA owing to time taken in upgrading the launch vehicle, McDonnell Douglas' Delta 2 rocket. The launch vehicle had failed to place a Korean communication satellite in its intended orbit on an earlier mission. Major problems with other launch vehicles, such as Pegasus XL, are threatening the future of many NASA projects due to delayed launches. The consequences of relying on an unproven family of mid-size rockets are also discussed.

Have NASA's scientists been the victims of excessive expectations?
Article Abstract:
The loss of four spacecraft in 10 week has raised questions about whether NASA's better, faster, cheaper approach is effective or justified. Some observers feel that the Jet Propulsion Laboratory has found it difficult to adapt to this approach, with some of its programmes now experiencing problems. However, other elements of NASA's science programme have been more successful with the better, faster, cheaper approach. It now appears that NASA will have to make difficult decisions about which projects to cancel.
