Infrastructure needed for future space exploration

The United States is facing a crisis in its human space program. The huge investments in the Space Shuttle and the International Space Station (ISS) programs are leveling off, but the replacement for the Space Shuttle and the new space exploration architecture plans for future visits to the Space Station and missions to the Moon and Mars (called the “Vision for Space Exploration� or VSE) are still in early development. A “gap� in the ability of the United States to provide human and cargo transportation to and from the ISS is now of grave concern as the fleet of Space Shuttles is reaching the end of its operational life. This type of unfortunate situation has happened before (1975 to 1981) between the end of Saturn-Apollo rocket operations and initial operations of the Space Shuttle.

Review: Tourists in Space

Over the last several years, the concept of personal spaceflight (aka space tourism) has gained acceptance from the broader public, even if the development of the vehicles intended to serve this new market has lagged (see “Where’s my rocketship?� The Space Review, July 7, 2008). What was once treated with winks and giggles and guffaws is now given serious consideration not just by the space industry but the much larger travel and tourism industry as well. So much so that someone can publish a book with the title Tourists in Space: A Practical Guide and have it treated as just that: a nuts-and-bolts look at suborbital and orbital space tourism, particularly for those people considering signing up for a ride into space.

NASA considers continuing shuttle use after 2010

Michael Griffin, administrator of the American space agency, NASA has ordered a study into considering the possibility of continuing the usage of the space shuttle, a space vehicle that takes astronauts to the International Space Station. The agency originally planned to retire all shuttles in 2010 after mission STS-134, but concerns over staff job losses that were created by the Space Shuttle program caused Griffin to order the study. The space crafts have been in use since 1981 and it's replacements, the Ares rockets, will not be in use until 2015 causing a 5 year gap where NASA will have no manned space flights, which is the reason the agency is considering extending usage for five more years, when the vehicles can be immediately replaced by their successors.

Lytic Transglycosylase MltB of Escherichia coli and Its Role in Recycling of Peptidoglycan Strands of Bacterial Cell Wall

The cell wall is an indispensable structure for the survival of bacteria and a target for antibiotics. Peptidoglycan is the major constituent of the cell wall, which is comprised of backbone repeats of N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM). A peptide stem is appended to the NAM unit, which in turn experiences cross-linking with a peptide from another peptidoglycan in the final steps of cell wall assembly. In the normal course of bacterial growth, as much as 60% of the parental cell wall is recycled, a process that is not fully understood. A polymeric cell wall is fragmented by the family of lytic transglycosylases, and certain key fragments are transported to the cytoplasm for recycling. The genes for the six known lytic transglycosylases of Escherichia coli were cloned, and the enzymes were purified in this study.

Letter: Finding space for contemporary art

We were delighted with your interview with Bridget Riley (July 5) celebrating her role in and recollections of the founding and history of Space, which supports artists by providing affordable studio space, and supports local communities with cultural programmes in east London. To bring your interview up to the present day, Space is celebrating 40 years with a selling exhibition of work by 55 current Space artists, including this year's Turner prize winner, Mark Wallinger. The interview rightly says that Space is still going strong, but we are constantly at risk as leases come up for renewal and we are exposed to the property market of east London, where former factory buildings are in high demand for loft conversions and the 2012 Olympics further affect affordability of property.

A Cold War Meeting in Space 33 Years Ago Today

On July 17, 1975, something momentous and unprecedented happened: two Cold War-rivals met in space. The Apollo-Soyuz Test Project saw spacecraft from the United States and the Soviet Union docking together in space, ushering in a new era of cooperative ventures between the two countries that once were rivals in the "space race." Preparing for the mission, the astronauts and cosmonauts had to visit each other's countries for training, and the two space agencies had to share classified information with each other in order for the rendezvous and docking to work successfully. A few years ago, Tom Stafford, one of the American astronauts said the Apollo-Soyuz mission "showed the whole world that if the Soviet Union and America could work together in space, they could work together on the Earth.

Aldrin Warns that NASA will fall Behind Russia and China in Space Exploration

The world knows the huge potential China and Russia have for space exploration. Russia is maintaining a strong presence in space with their sturdy Soyuz program and China has set its sights on having their very first "taikonaut" EVA at the end of this year. But where does this leave NASA? The US space agency has spearheaded the exploration of space for the last 50 years, but amongst all the talk about NASA setbacks, overspending and delays, could the glory days be coming to an abrupt end? In May, the legendary astronaut John Glenn spoke out against Shuttle decommissioning and last week, US Senator Bill Nelson called a meeting at Cape Canaveral to raise concerns about announced job cuts in 2010. Now, the most famous NASA ex-employee and second man on the Moon, Buzz Aldrin has voiced warnings that the US could lose its grip on space and beg

On-Chip Fuel Cell: Micro Direct Methanol Fuel Cell of an Air-Breathing, Membraneless, and Monolithic Design

This paper proposes a novel design for a microfuel cell as an on-chip power source and demonstrates its fabrication and operation to prove the concept. Its simple design is important from the viewpoints of fabrication (e.g., replication), integration, and compatibility with other microdevices. In testing, the prototype cell was able to generate electric power (maximum: ca. 1.4 μW) on methanol without pumps under both neutral and acidic conditions. As for the size, the electrode part of the cell (two cathodes and one anode) is 400 μm in width and 6 mm in length. The evaluation demonstrated that the proposed design is a promising on-chip power source for miniature devices.
