NASA's new planetary protection officer is open to reexamining how the agency deals with both government and commercial missions to Mars and other potentially habitable worlds in the solar system.
With few new missions in development, NASA's Mars Exploration Program is shifting towards operations of ongoing missions as well as technology development to support an eventual sample return effort.
If all goes as planned, NASA’s campaign to pinpoint sources and sinks of atmospheric carbon dioxide will get a major boost early next year with the launch of the Orbiting Carbon Observatory-3, a leftover satellite instrument modified to attach t…
NASA's fiscal year 2019 proposal will likely set up another showdown between NASA and Congress regarding the Europa Clipper mission, debating not only when to launch the spacecraft but also how.
NASA's vision for lunar exploration includes landing astronauts, from NASA and its partners, on the surface of the moon by the late 2020s, the agency's acting administrator said Feb. 20.
NASA’s topline budget will be flat for the foreseeable future — which means an effective decrease in real dollar funding for the agency. As a result, President Trump may see his moon plans come crashing down to Earth.
NASA's fiscal year 2019 budget proposal will include plans to end funding for the International Space Station in 2025, but leaves open the possibility of handing part or all of the station over to private operators.
NASA is beginning to study a contingency option for maintaining access to the International Space Station should commercial crew vehicle development experience delays, one that would turn test flights of those vehicles into operational missions.
NASA has given Sierra Nevada Corporation (SNC) formal approval for the company's first cargo mission to the International Space Station in late 2020.
To gauge the impact of the National Academies’ first Earth science decadal survey, it’s important to look beyond its list of 15 recommended missions and consider the warning the panel began conveying in its 2005 interim report: The U.S. Earth-observing program was in danger of collapse.
The Earth, and particularly its climate, is changing. Earth science, therefore, is also changing. And, with those changes, come revisions on not just the missions needed to carry out the science, but how they should be selected.
The approach NASA has taken with James Webb Space Telescope, with no ability to repair or upgrade the telescope after its launch, stands in sharp contrast to what it did with JWST’s predecessor, the Hubble Space Telescope. Some believe NASA should embrace servicing, and even assembly, of future space telescopes.
