A NASA mission to a potentially habitable moon of Jupiter has cleared a major review despite uncertainty about when, or how, it will launch.

Inspector general report warns of cost and schedule problems for Europa Clipper
As NASA prepares for a key review of the Europa Clipper mission, a report by the agency’s inspector general warns that the mission’s launch may face delays and significant cost increases.

NASA spending bill clears House subcommittee
A House appropriations subcommittee approved a spending bill May 17 that provides NASA with more than $22.3 billion but largely ignores an administration request for an additional $1.6 billion to support plans for a 2024 human return to the moon.

Europa Clipper instrument change could affect mission science
A NASA decision last month to replace an instrument on the Europa Clipper mission with a less expensive, but less capable, alternative is leaving scientists concerned about the ability of the mission to meet some of its objectives.

NASA dealing with cost growth on planetary science flagship missions
While NASA’s overall planetary sciences program is enjoying record funding levels, the agency is grappling with cost growth in two of its largest missions.

NASA budget proposal targets SLS
The White House’s fiscal year 2020 budget request for NASA proposes to delay work on an upgraded version of the Space Launch System and would transfer some of that vehicle’s payloads to other rockets.

Europa or Enceladus? If NASA switches from SLS to Falcon Heavy, it won’t have to choose
Switching from SLS to the Falcon Heavy may cause some trade-offs in designing both the Europa Clipper and the Europa Lander to fit the smaller rocket. However, the cost savings could be plowed into an Enceladus orbiter.
