NASA is getting extra bang for its buck these days by relocating existing spacecraft and using them for additional research above and beyond their primary missions.
ARTEMIS has joined the ranks of Stardust-NExT and EPOXI as recent examples of "repurposed" spacecraft. Launched in 2007, the two ARTEMIS probes are now in orbit around the Moon after completing their research to study the Sun's interaction with Earth's magnetic field.
The two were originally part of a set of five spacecraft in the Time History of Events and Macroscale Interactions during Substorms (THEMIS) program. The other three THEMIS spacecraft are continuing their solar-terrestrial physics studies.
These two -- renamed Acceleration, Reconnection, Turbulence and Electrodynaimcs of the Moon's Interaction with the Sun (ARTEMIS) -- were moved from their previous locations at Lagrange points to lunar orbit through a complex set of orbital maneuvers. The first reached lunar orbit on June 27 and the second on July 17. Their orbits will take them within 60 miles of the lunar surface where they will collect data about the Moon's core, surface composition, and magnetic properties. The probes are expected to return data from their new locations for seven to 10 years.
UPDATE: NASA has refined the landing time to 5:56 am EDT on Thursday, which is reflected below.
STS-135 (Atlantis), the final space shuttle mission, closed the hatches with the International Space Station (ISS) today as it readies to return home.
The hatches were closed at 10:28 am EDT. The shuttle crew went to sleep at 1:59 pm EDT this afternoon to get ready for an early morning undocking tomorrow, Tuesday, July 19, at 2:28 am EDT.
Landing is currently scheduled for 5:56 am EDT at Kennedy Space Center on Thursday.
Rep. Lamar Smith (R-TX), vice-chairman of the House Science, Space and Technology Committee, is calling for a "better space program."
In an op-ed in today's Space News, Rep. Smith says that "America deserves to be inspired by the heavens again." As others in Congress have done, he criticized the Obama Administration for not complying with the 2010 NASA Authorization Act.
Wheel stop for STS-135 (Atlantis) on Thursday will mark the end of the space shuttle program and NASA and its Kennedy Space Center (KSC) are accelerating their transition to the new era of commercial space.
The day before the launch of STS-135, KSC signed a Space Act agreement with Sierra Nevada, which is developing the Dream Chaser spaceplane. The agreement will allow KSC to work with Sierra Nevada to define and execute launch preparations and post-landing activities for Dream Chaser.
Today, three days prior to STS-135's landing, an unfunded Space Act agreement was signed between NASA and the United Launch Alliance (ULA). ULA is a Boeing-Lockheed Martin joint venture that builds and launches the Delta IV and Atlas V families of launch vehicles. The agreement will pave the way for consideration of using the Atlas V as a launch vehicle for future crew spacecraft. Right now, SpaceX and Orbital Sciences Corp. are developing new launch vehicles (Falcon 9 and Taurus II) to launch cargo and crews to the International Space Station (ISS) as part of the commercial crew program. Some argue that the Atlas V and Delta IV, which already exist and are used to launch spacecraft for critical national security space missions, could be upgraded for human spaceflight, too.
NASA is gearing up to launch its next Mars rover -- the Mars Science Laboratory (MSL) or "Curiosity." An open question is where on Mars it should land.
That question will be answered on Friday, July 22 in a press conference at the National Air and Space Museum (NASM). The museum has a life-size model of Curiosity on display.
The press conference will be held at 10:00 am EDT and will be shown on NASA TV (http://www.nasa.gov/ntv).

The House had planned to be in recess, but decided to remain in session because of the debt limit/deficit reduction talks.

Among the agencies whose budgets would be cut by the House Appropriations Committee in the FY2012 Commerce-Justice-Science (CJS) bill is the White House Office of Science and Technology Policy (OSTP). The cut of more than 50 percent of its budget request is the result of congressional unhappiness with OSTP's continued efforts to engage with China despite language in the final FY2011 Continuing Resolution that it refrain from doing so.
The committee's report on the FY2012 CJS bill says the following:
"The Committee recommends $3,000,000 for the Office of Science and Technology Policy (OSTP), which is $3,647,000 below fiscal year 2011 and $3,650,000 below the request.
"Coordination with China.-OSTP has chosen to disregard a strong and unambiguous legislative prohibition on bilateral engagement with China or Chinese-owned companies that was included in the Department of Defense and Full Year Continuing Resolution Act, 2011 (Public Law 112-10). OSTP and the White House raised no concerns about this language while it was under consideration. Only after the Committee asked OSTP about its compliance with the provision did OSTP claim that the language infringed on Constitutional prerogatives and acknowledge an intention to proceed with prohibited activities. Even then key information about a scheduled bilateral event was omitted. OSTP's behavior demonstrates a lack of respect for the policy and oversight roles of the Congress."
The report goes on to say that the remaining OSTP funding is to be prioritized to coordinate and improve government programs for STEM education.
The Associated Press ran a story about it yesterday.
Senator Kay Bailey Hutchison (R-TX) continues to assail the Obama Administration for "foot-dragging" on its legislated requirement to build a new space launch vehicle.
In her weekly column on her website, Sen. Hutchison again blamed the Obama Administration for failing to implement the 2010 NASA Authorization Act of which she was a primarily author: "Despite overwhelming Congressional support when this legislation was approved, the Obama Administration unfortunately is dragging its feet in implementing the new law. This foot-dragging is more than just failing to carry out the law, as the Constitution requires. The Administration's delays put current and future American jobs and industries at risk, and hand over to competing nations a golden opportunity to take the global lead in technology."
After listing some of benefits of past investments in space activities broadly, not just NASA, she states: "The contributions our space program has made to science, our national security, and our economy illustrate why we can't abdicate our leadership role in the world."
Yesterday, National Public Radio's Science Friday host Ira Flatow interviewed Michael Turner of the University of Chicago and science writer Ron Cowan about the plight of the James Webb Space Telescope (JWST).
The audio of the program is available on Science Friday's website.
Turner defended the program, using the age-old argument that NASA's programs push the envelope of science and technology and that "once in a while" there is an overrun. Not all would agree with Turner on the frequency of cost overruns. A 2004 Congressional Budget Office (CBO) report found an average of 45 percent cost growth for the 72 NASA programs it analyzed.
Cowan pointed out that supporters of the project were not forthright about its costs in the beginning, and Turner agreed that was one of the lessons learned from last year's Casani report on JWST -- that one must be upfront about the costs. As for now,Turner argued that the program was about 75 percent done and ending it now would be "penny wise and pound foolish."
Cowan said he is concerned that NASA is not saying how much more JWST will cost if the launch slips to the early 2020's. Turner countered that NASA has come up with a new plan for completing it and is negotiating with the White House Office of Management and Budget (OMB) and some things have to be done behind closed doors.
Updated versions of our fact sheets on NASA's FY2012 Budget Request and on a Legislative Checklist of Major-Space Related Legislation in the 112th Congress are now available.
The NASA FY2012 Budget Request fact sheet includes the funding recommendations adopted by the House Appropriations Committee Wednesday in marking up the Commerce-Justice-Science (CJS) bill.
The Legislative Checklist fact sheet shows House passage of the Department of Energy (DOE) appropriations bill today, and committee markup of the Commerce-Justice-Science and the Interior-Environment appropriations bills earlier this week. The CJS bill includes NASA and NOAA; the Interior-Environment bill includes the U.S. Geological Survey (USGS), which operates the Landsat satellites.
