That’s in comets’ nature.Hopes for a big show by the advertised “comet of the century” came to a dismal end as Comet ISON broke up after its perihelion swing around the sun on November 28th. The announcement was a bit of a roller-coaster ride. Initial reports failed to see it re-emerge after its fiery plunge behind the sun, but then a broad, wedge-shaped tail appeared in SOHO images long enough to keep hope alive. It rapidly dimmed, however, leading astronomers to conclude it had been ripped apart into smaller fragments that quickly burned out.Richard A. Kerr, writing for Science Magazine, said that comets often break up:Comet ISON’s disintegration into a cloud of debris as it neared its closest approach to the sun on 28 November came as no surprise to astronomers. They knew the kilometer-size “dirty snowball” or nucleus at the heart of the comet had never been tested by the rigors of a passage through the inner solar system. And no icy comet nucleus was all that sturdily built eons ago during the formation of the planets…. Astronomers now believe that the sun’s searing heat and its wrenching tidal pull—stretching the nucleus like so much putty—did in the nucleus hours before its closest approach to the sun.Heat and tidal stress are destructive processes. PhysOrg says Comet ISON lost three trillion tonnes of its mass per second as it rounded the sun. Kerr assumes that comets are dirty “snowballs,” borrowing the terminology of earlier astronomers who thought that they originated far away from the sun (wrong; see 1/25/08 and 9/09/08). What’s proven more interesting than the snow is the dirt. The Deep Impact (9/07/05) and Stardust (3/14/06, 12/18/06) missions surprised astronomers by showing evidence of minerals that required high temperatures to form (4/18/11, 7/29/11), 9/24/08).Kerr assumes that comet nuclei were “built eons ago,” (albeit not “sturdily”), but no one has observed any solar system body accrete from dust or ice. What they do observe is bodies like comets blowing out material (like a comet tail, the geysers of Enceladus, or the volcanoes of Io), or breaking up, or both (5/10/06). Planetary scientists have had difficulty explaining the source of comets (e.g., 9/03/03, 10/05/03) and their longevity (e.g., 12/27/07).As it is in the nature of comets to break up, it is in the nature of science reporters to use assumptions as a shield for ignorance. Kerr speaks glibly about “the formation of the planets.” OK, Mr. Kerr, how did they form? Using only the laws of physics, and no design, can you get small particles to form an Earth or a Jupiter? (See 6/23/11, 5/21/09, or for comets, 10/01/07). Do you have any observational evidence for your model? Remember, some dust disks around other stars were thought to be early solar systems, but were later re-interpreted to be remnants of planets breaking up (see 7/07/12).We’ve reported many times about the short lifetimes of comets and how this poses problems for belief in billions of years.

Lendlease Corp. closed on the final phase of the Army’s Privatization of Army Lodging (PAL) program, securing $250 million in additional project debt, the international property and infrastructure group said Thursday.The transaction brings the company’s total senior debt financing for the initiative to $715 million and allows it to add 2,058 hotel rooms located on Fort Lee, Va., and Fort Benning, Ga. Lendlease’s privatized hotel portfolio now stands at 12,492 hotel rooms on 41 military installations.The $1 billion PAL program began in 2009, with Lendlease assuming ownership of hotel facilities on 10 Army posts. In 2010, the company was asked to implement the second phase of the program at an additional 11 posts. Lendlease was offered the third phase in October 2011. InterContinental Hotels Group (IHG), one of the world’s largest hotel groups, is the PAL hotel operator.“Lendlease is honored to lead the Department of Defense’s only lodging privatization program,” Claire Johnston, managing director for communities, said in a press release. “Leveraging the government’s assets and raising private funds has resulted in exceptional lodging facilities that exceed the needs of today’s military and government traveler and which deliver on Lendlease’s commitment to sustainability and innovation,” Johnston said.By the end of the calendar year, Lendlease plans to deliver the nation’s first all-cross laminated timber hotel at Redstone Arsenal, Ala. The 58,850-square foot, four-story hotel will have 92 guestrooms; it will be operated under IHG’s Candlewood Suites brand.To date, 14 Holiday Inn Express hotels have been delivered through the PAL program with another five currently under renovation. Lendlease also has delivered five new Candlewood Suites hotels with three under construction. One Staybridge Suites is under construction at Fort Belvoir, Va.A list of IHG Army Hotels locations can be found on the project website. Dan Cohen AUTHOR
