NASA's stated goal of returning humans to the moon by 2020, which received a tentative boost in February with an affirmation in President Barack Obama's budget request for fiscal year 2010, is reportedly now in danger.
According to a report in the Orlando Sentinel quoting unnamed NASA engineers and contractors, the space agency's timelines "are quietly being revised" in light of ongoing technical and budgetary problems. That revision, engineers told the newspaper, means the "2020 date to send humans back to the moon is in deepening trouble."
The agency has pushed back by two years its internal timeline for the scheduled moon launch of Ares V, a planned heavy-cargo carrier rocket, according to the Sentinel report. NASA had reportedly tagged the Ares V with a 2018 internal target—which builds in leeway for unforeseen problems—for a lunar launch, while announcing a 2020 date to the public. Grey Hautaluoma, a spokesperson for NASA, declined to comment on the Sentinel story. "We won't have any comment about our budgets and schedules until the 2010 budget is released next month," Hautaluoma said.

Space shuttle Discovery touched down safely at 3:14 P.M. (Eastern Daylight Time) at Kennedy Space Center in Florida, completing its 13-day mission to the International Space Station (ISS). The landing time was pushed back from 1:39 P.M. due to uncertain weather at the landing site earlier in the day.
Discovery delivered a 45-foot (14-meter) truss segment to the ISS, completing the station's 335-foot (102-meter) "backbone," as well as the final set of solar arrays needed to power the station once its crew swells from three to six in the coming months. The ISS now boasts 38,400 square feet (3,570 square meters) of U.S. solar panels, nearly a full acre, generating about 120 kilowatts of electricity. (Unlike solar-powered buildings here on Earth, the space station doesn't need to worry about cloud cover.)

The next space shuttle launch has been pushed back again due to lingering safety concerns stemming from the last shuttle mission in November. NASA needs more time to analyze and possibly conduct further testing on the three flow-control valves that regulate the flow of hydrogen gas from the main engines to the external fuel tank, the space agency announced late Friday. Before the postponement, Discovery had been scheduled to depart on its servicing mission to the International Space Station as early as Friday, which was itself a pushback from an original launch date of February 12.
The safety issue came to light after the Endeavour mission in November, when engineers discovered that one of the valves had been damaged in flight. NASA removed and inspected the valves on Discovery but has been working to identify why Endeavour's valve broke and what safety risks a similar occurrence might pose to the Discovery mission.
