Update # 311 of Sunday, February 17, 2008
Decaying U.S. satellite to be blown up! / Solar system "analog" (minus Earth et al.) found with microlensing / NASA FY'09 budget request holds science promises

Missile attack on out-of-control U.S. satellite authorized!

Three Aegis missiles have been reprogrammed to intercept USA 193 just before it reenters anyway / Objective is destruction of hydrazine tank which would survive but leak / Little debris to be left in orbit, most to fall into an ocean

Three Standard 3 missiles will be ready on three Aegis vessels some time within a week: One will be fired at the experimental NRO satellite USA 193 that does not respond to commands, then the outcome of the engagement will be analyzed, and if need be two more missiles could be fired within the following two days. That's the essence of a DoD briefing on Feb. 14 at 19:30 UTC that followed three weeks of preparations. The central objective is to blow up the hydrazine tank of the satellite as models show that it would survive to the ground but leak the toxic fuel into the environment. According to the DoD it would also be nice to have the "5000 pound" (now we know!) spacecraft in several pieces instead of one. Getting rid of classified technology is not the driver, we are assured, as it would melt beyond recognition anyway. The engagement will take place just before USA 193 would reenter anyway: Thus as little debris as possible will remain in orbit, endangering other spacecraft.

First microlensing discovery of a planetary system - again involving amateur astronomers

Two detected planets have roughly Jupiter and Saturn masses / Orbits also comparable / Sorry, no Earth yet ...

Searches for extrasolar planets have uncovered an astonishing diversity of planetary systems, yet the frequency of solar system analogs remains unknown. The gravitational microlensing planet search method is potentially sensitive to multiple-planet systems containing analogs of all the solar system planets except Mercury. Astronomers from several microlensing searches - involving amateur astronomers to further improve the joint light curve - now report the detection of a multiple-planet system withr microlensing! They identify two planets with masses of ~0.71 and ~0.27 times the mass of Jupiter and orbital separations of ~2.3 and ~4.6 AU orbiting a primary star of mass ~0.50 solar masses at a distance of ~1.5 kpc. This system resembles a scaled version of our solar system in that the mass ratio, separation ratio, and equilibrium temperatures of the planets are similar to those of Jupiter and Saturn. These planets could not have been detected with other techniques; their discovery from only six (!) confirmed microlensing planet detections suggests that solar system analogs may be common!

Details of seven(!) science new starts planned by NASA explained

At a telecon NASA science managers have provided further details about the State of Science at NASA, so to speak: This budget (request) is "unlike any in recent memory," says Alan Stern: Not only are the seven new starts of missions more than in the last 3 years combined, there are also significant increases of data analysis money etcl. in the plan, "essentially repairing all the cuts" of recent years or even improving on earlier values. The new starts are two Earth science missions and the
  • Joint Dark Energy Mission which was rated very highly by independent reviews in astronomy; a
  • Solar Probe flying several times through the solar corona; an
  • Outer Planets Flagship mission most likely together w/international partners, esp. ESA and individual nations (three destinations are in the running, only a mission to Enceladus is gone; further downselection later this year); and two
  • Small lunar missions, first an orbiter in 2011 (to be launched together with GRAIL), then two landers launching together on the same rocket in 2013 or 14 (those will go to the lunar N and S poles, forming the "U.S. anchors" of an International Lunar Network of 8 to 10 stations). There is also a
  • Mars Sample Return Mission in the 2020 timeframe that does not count as a full "new start" as not much money is to be invested in the next few years - first there will be many 'architecture studies'. The MSRM comes with an absolute budget cap of 3.3 billions of todays dollars for the U.S. contribution, but international partners are welcome.
The Mars Sample Return Mission (which together with international money could end up at a total of 4.5 billion dollars) can only be attacked in earnest when the Outer Planets mission has been paid for: More than one of these multi-billion dollar monsters cannot be afforded at one time. Getting the Outer Planets project going will involve a lot of tricky negotiations with the (all but essential) international partners: ESA e.g. has its own ideas and priorities in the outer solar system ...

NASA FY'09 budget request: 1.8% increase, Orion in 2015 - and lots of new science in the next decade

Small lunar landers and an orbiter, mars sample return preparations, an outer planets flagship and a Dark Energy mission in the plans - soundness of overall strategy promptly questioned in Congress ...

The NASA FY 2009 budget request for NASA - presented on Feb. 4 - is $17.6 billion, a 1.8 percent increase over the FY2008 enacted budget, along with a steady, five-year runout that includes an increase each year of around 2.4 percent. W.r.t. the manned program it was stated: "With full funding for Orion and Ares I provided by the Congress this year and the budget currently projected to be available for NASA, our best estimates still maintain an initial operational capability for the Orion and Ares I of March 2015. NASA will again need its full funding request this year in order to maintain that schedule, though the Constellation team strives to bring the Orion and Ares I on-line sooner." So far, the direction of the program will not change (but there's a certain election this year).

If the '09 budget ends up in the proposed arena, science - with a budget of $4.44 billion that includes Earth observation, the solar system and astronomy - seems to be in for some new adventures: "The Science Mission Directorate has an exciting budget request that initiates seven new missions - put in perspective, this is more than in the previous three SMD budgets combined. [...] NASA's science and exploration mission directorates are working together to develop two small lunar landers, and SMD is initiating a series of new and exciting missions heading to the moon over the next decade, like the LADEE small orbiter to characterize the atmosphere and lunar dust environment. This year, we are especially looking forward to the launch of India.s Chandrayaan-1 spacecraft, which includes two NASA payloads, as well as the launch of NASA.s Lunar Reconnaissance Orbiter and LCROSS secondary payload.

For Mars, we are focusing much of our efforts after 2013 to carry out a sample return mission to launch by 2020. In planetary science, the FY 2009 budget also initiates development of a flagship outer planets mission, which we hope will include significant international collaboration. In astrophysics, we are initiating the Joint Dark Energy Mission, the highest priority among astrophysicists, and in heliophysics we are initiating Solar Probe Plus, a high priority heliophysics mission, starting in FY 2009." JDEM will fly in the middle of the next decade and won't get much next year, but full funding is foreseen in the funding wedge for subsequent years. Is all well now? Not to House Science and Technology Chairman Bart Gordon for whom "science programs face an uncertain future as funds are shuffled from one science account to the next in order to free up funds for proposed new initiatives. While those new initiatives may be laudable, the ability to sustain them under the Administration's proposed budget plan is open to question."

Another 'most distant galaxy' - without a redshift

The HST has found the strongest evidence so far for a galaxy with a redshift significantly above 7.

Iran shoots a 2nd sounding rocket into space - now strange report that it put a satellite into a low orbit ...

As last year the flight was first thought to be suborbital at best (with a payload named Kavoshgar) - but after two weeks Iran is suddenly talking about a spacecraft in orbit, sending data. Or is this all just a misunderstanding or bad translation? In any case - and just as many years ago - there is now talk of launching a satellite on a domestic rocket to a much higher orbit, this time 2009 under the name Ormid (and no fewer than five by 2010): Press TV, AP, AFP.
