NASA has announced plans for sending humans back to the Moon, as a first step to Mars.

A 2018 lunar mission is proposed, where a crew of four would remain on the Moon for as long as a week. A minimum of two lunar missions a year is planned, with astronauts remaining as long as six months.

Some of the technology had previously been proposed for replacement of the Space Shuttle.

• Astronauts will be launched in a capsule, similar in concept to that used for the Project Apollo but three times larger. The top part of an Exploration Transportation System (ETS), the Crew Exploration Vehicle (CEV) will be a capsule attached to a service module which contains supplies, power, and propulsion units. The CEV is designed for use in Earth orbit.
• On lunar missions, crew or cargo versions of a Lunar Surface Access Module (LSAM) would be used with a CEV. The LSAM will have design concepts related to the Apollo Lunar Module, with a four-legged landing unit carrying an ascent stage.
• An Earth Departure Stage (EDS), a powerful propulsion unit, will be used to move CEV and LSAM units out of Earth orbit, such as on lunar missions.
• Heavy Launcher unmanned cargo rockets will be used for heavy loads of equipment.
• The launch rockets, Shuttle Derived Launch Vehicles, will use engines developed for the Shuttle program.
  • CEV will be launched atop a Crew Launch Vehicle (CLV), a single solid fuel booster with a second stage using a shuttle main engine. The CLV can carry a payload of 25 metric tons into low Earth orbit.
  • The heavy-lift system uses a pair of longer solid rocket boosters and five shuttle main engines to put up to 125 metric tons in orbit — about one and a half times the weight of a shuttle orbiter.
• The use of a Launch Escape System (LES) will improve safety. A LES is a top-mounted rocket that can quickly remove the crew capsule away from an exploding or otherwise dangerous rocket.

For a lunar mission, the LSAM and EDS would be placed in orbit by a cargo launcher, then a CEV would dock with the assembly before leaving Earth orbit.

The goal is to begin production of the new spacecraft by 2011.

• Robotic missions will be sent, probably the first one in 2008.
• Past experience with lunar dust is being used in designing equipment and spacesuits which may encounter it.
• Surface mobility with open and pressurized rovers for use in such missions is also being developed.
• The CEV can be reused up to ten times.
• Crew capsule, upon return to Earth, will set down on dry land. It can also land on water.
• The CEV and lunar lander ascent stage use methane as fuel, as methane may be available on Mars.
• Eventually the designs could be expanded to support six astronauts for a trip to Mars.

The plans are a means to implement President Bush’s “Vision for Space Exploration” program. Goals include:

• Implement a sustained and affordable human and robotic program to explore the solar system and beyond;
• Extend human presence across the solar system, starting with a human return to the Moon by the year 2020, in preparation for human exploration of Mars and other destinations;
• Develop the innovative technologies, knowledge, and infrastructures both to explore and to support decisions about the destinations for human exploration; and
• Promote international and commercial participation in exploration to further U.S. scientific, security, and economic interests.

Jack A. Weil, founder and CEO of Rockmount Ranch Wear died on August 13 at the age of 107 in Denver, Colorado. He was the oldest working CEO in the United States. He was also known as “Papa Jack”.

He was born on March 28, 1901 in Evansville, Indiana. In 1946, Weil rented a space at 1626 Wazee Street in Denver and set about trying to create a fashionable yet practical identity for the western ranchers of the region.

Weil was well-known for coining the phrase “The West is not a place, it is a state of mind.” He was the first person to put snaps on Western shirts, patented the saw-tooth pocket design seen on many Western shirts, and was credited with inventing the bolo tie.

In 2001, he told Associated Press, “I learned fast you can’t sell to cowboys; they have no money. You have to appeal to the cowboy in everyone and sell to them.”

Among his customers were Ronald Reagan, Bob Dylan, Eric Clapton and Nicholas Cage. More recently, Rockmount shirts were worn by the late Heath Ledger and Jake Gyllenhaal in the 2005 Academy Award-nominated movie, Brokeback Mountain.

Weil’s wife, Beatrice Baum, died in 1990, followed by his son Jack B. in January 2008.

“I never wanted to be the richest man in the cemetery,” he told his grandson and current president of the family business.

Chemicals in the Thompson River were said to be found after four Canadian Pacific Railway (CP Rail) cars containing chemicals derailed near Lytton, British Columbia, Canada on Tuesday night.

The derailment occurred just northeast of Lytton when a landslide hit in the middle of a freight train with about 100 cars at around 7:00 pm PDT (02:00 UTC) Tuesday evening. One car remained on the tracks, another was on a river bank, and two were submerged in the Thompson, one of them fully submerged and the other partially submerged. CP states that the cars were carrying the chemical ethylene glycol, commonly found in products such as antifreeze and windshield washer fluid. Glycol is water soluble and biodegradable but is causing concern to local fisheries and people dependent on aquatic life survival. Even though there is not enough chemical to be toxic after dilution in the water, there is still expressed concern that it may cause additional stress to aquatic life.

Despite protective measures, like a protective double hull, investigations found that broken valves and holes are causing the chemical to leak into the river. CP Rail originally denied that any chemical was leaking, but is now driving efforts to plug the leaks.

The Thompson River is a tributary of the larger Fraser River. The area is sensitive to harm because migrating salmon pass through and are in already in dwindling numbers in recent years.

On April 8, 2005, police picked up an unidentified man wandering the streets of Sheerness, United Kingdom. The man was wearing a formal black suit and white shirt with all labels removed, and was soaking wet, as if having been in the sea.

He has not spoken a word since he was found, but when given pencil and paper he drew a piano. Seeing the picture of the piano, the medical staff at the Medway Maritime Hospital where he was admitted showed him the piano in the hospital chapel. To their amazement he sat at the instrument and played classical and pop music for several hours.

Many press reports have emphasized the piano playing, and the man has been labelled “The Piano Man” by many news services, although the hospital staff has been calling him “Mr. X.”

However, the chaplain of the hospital, the Reverend Steve Spencer, said the man “is not the virtuoso that he has been portrayed in the press. He knows a small number of tunes and plays them over and over. I recognized some John Lennon and a snippet from Tchaikovsky’s Swan Lake.”

The man also pointed to a flag of Sweden when shown an atlas, initially leading the hospital staff to believe he was from Sweden. To date this lead has not panned out. A different account from the National Missing Persons Helpline (NMPH) indicated that the man actually drew the flag.

The NMPH is appealing to anyone who recognizes the man to contact Teri on +44 20 8392 4509. All calls will be treated as confidential. The NMPH can also be reached at +44 500 700700. Emails can also be sent to id@missingpersons.org.
