Inflatable Space Module Set For ISS Mission

Bigelow Aerospace’s inflatable BEAM module — a new lightweight activity module, part of Bigelow’s continued endeavors toward putting into use a wide range of portable expandable habitation spaces, including the living-and-working-space BA-330 (pictured above) — has been scheduled for a March NASA mission to the space station.

The Bigelow Expandable Activity Module will be sent to the space station in the SpaceX Dragon capsule, and will be berthed to the space station’s Tranquility node. It will then be pressurized and expand to its full size with air stored in the compressed module.

BEAM will then be monitored through a test period of two years. Astronauts will periodically enter the module to inspect it and gather performance data.

After the test period, BEAM will be jettisoned and will re-enter Earth’s atmosphere, burning up.

Bigelow Aerospace is working with NASA to produce expandable systems, including habitational systems, and has already completed two succeful missions with its Genesis pathfinder I and II spacecraft — missions noted for their relatively low-cost.

The low cost comes from the low weight of the Bigelow constructions — one-tenth the weight of some similar modules. Improvements in craft weights have come in large part from advances in lightweight, strong materials such as Kevlar.

The BEAM module walls are made of many layers of Vectran, a material similar to Kevlar but made of spun liquid crystal fibers, and fire-resistant Nomex.

The Nevada-based company is working towards a standalone space habitat in addition to its current module projects. A large expandable module is already being developed by Bigelow — three times the size of any individual module on the ISS, the BA330 is designed for a maximum crew size of six in its 330-meter square environment. The BA330 is designed to be used in conjunction with other modules to build larger module complexes in space.

Possible new law of nature on the way

The world of physics is excited about strong but early evidence about the behavior of muons, paricles identical to electrons only 200x more massive (heavier), which once born take 2.2 microseconds to decay into an electron, and which spin like tops. In a new, extremely precise measurement, they were made to wobble using magnetic fields but they unexpectedly wobbled quite significantly faster than the Standard Model suggests they would. They might spin so fast due to an unknown force caused by an unknown particle, and this is what is so exciting.

“We found that a muon … is not in agreement with our current best theory of physics at the subatomic level, and … it potentially points to a future with new laws, new particles and new forces in physics which we haven’t seen to date,” said Professor Mark Lancaster at U of Manchester.

“The main goal of the experiment is to make the measurement and compare with the theory, and if they disagree then it’s telling us that there’s something in nature which is not in the theory,” explained James Mott at Fermilab.

The four known forces of nature (gravity, electricity, two nuclear forces: strong and weak interactions) have left scientists without an answer for some observed phenomena, such as the speed at which galaxies spin (faster than the best model suggests). Therefore, they continue to search for glitches in their already-tight models which might point them things they don’t yet know about.

The most recent work was done at Fermilab (Muon g-2 experiment), but a similar experiment was already done earlier at the Large Hadron Collider. These tools accelerate particles in large rings at close to the speed of light.

The evidence needs more tests for greater certainty, particularly to rule out the possibility of a systematic error, and particularly with a new, independent experiment, but physicists will be chasing this line of experiment eagerly.

“This is outstanding confirmation of experimental technique, and very, very suggestive of the possibility of new physics,” noted scientist David Hertzon of U of Washington.

YANGON, Myanmar – Kayin internally displaced people are desperate for food, clothing and shelter, hiding in the forest from the air strikes of the Myanmar military.

The IDPs fled to neighboring Thailand, but Thai government turned them back. However, Wednesday morning the Thai government opened Maeseli jetty in Maehaungsaung district to sending rations and medicines over the border to Kayin state, according to a Thai media.

YANGON, Myanmar -They were charged under the country’s media law with inciting government employees to join the popular civil disobedience movement (CDM) through social media.

Celebrities took part in the NLD election campaigns and are thought to have played a large part in influencing the public, particularly Myanmar’s youth, to vote for Aung San Suu Kyi.
