  Japan
Japan had begun rocket studies in 1955, when a group at the University of Tokyo launched a tiny pencil rocket.
ISAS began in 1964 as the institute of Space and Aeronautical Science at the University of Tokyo.
The institutes principle role is to oversee rocket, satellite, and balloon projects from the initial plan and design to liftoff and data acquisition, and to organize and support research activities of university scientists.

  Lambda - Wikipedia, the free encyclopedia
Lambda (uppercase Λ, lowercase λ) is the 11th letter of the Greek alphabet.
The configuration of the sutures resembles an upper case lambda, and the suture between each parietal bone and the occipital bone is called the lambdoid suture.
Lambda is used in art and photography to refer to a digital Type C print or the equipment used to produce it.

 Could cyclic universe explain mystery? - Space.com - MSNBC.com
Lambda was revived in the late 1990s when astronomers discovered that the universe was not only expanding, but that it was doing so at an accelerated pace.
Scientists experimented with a varying lambda before within the context of the standard Big Bang model, but it didn't work because the time required for it to reach its current low value was far longer than the known age of the universe.
Because a high lambda prevents the universe as we know it from forming, early cycles of the universe would have been void of galaxies, stars and life; only in later cycles, when lambda had decreased to a much smaller value, could matter coalesce to create the world we inhabit today.

 Technical Aspects of Ballistic Missile Defense
In the rocket literature, propellants are characterized by their "specific impulse"-- Isp, measured in seconds, which is simply V_e/g.
The third row is the mass ratio m from the rocket equation, while the fourth row is the energy efficiency in converting to kinetic energy of payload the internal energy of a mass of propellant equal to the initial mass of the rocket less the final payload.
The rocket launch flame will be detected by the Defense Support Program (DSP) satellites in geosynchronous orbit within considerably less than a minute after launch, and an approximate location of the launch site and a direction of the missile is established in that way.

 Launch Options   (Site not responding. Last check: 2007-09-01)
This rocket was first launched in 1967 and its principle uses were mainly Apollo lunar missions.
Also, the rocket has not been operational since 1973 and a rocket with the capability of carrying a payload of 120 tons is excessive for our needs.
The Saturn V rocket is one of the most powerful rockets ever made, but is not suitable for our mission.

 The Lambda Incident
For the beacon to cause a resonance reversal, its displacement field would have to be correctly calibrated to neutralise the one within the dimensional rift, but unfortunately the advanced sensor equipment in the Lambda Complex could not scan the rift because it was too close to the anomaly.
Unfortunately no rockets could be launched while “lock-down” was in effect, and an “all-clear” signal would have to be transmitted.
The Omega satellite entered geo-stationary orbit, and the scientists in the Lambda and Gamma labs used the sensor telemetry to correctly calibrate the displacement beacon to initiate a resonance reversal.

As bizarre as these new constituents may sound, you don't have to be a rocket scientist to appreciate the most mysterious ingredient of them all.

The embarrassment of having to resurrect the obsolete quantity Lambda is compounded when unification theories are used to predict its value.

 Lambda
Lambda (upper case Λ, lower case λ) is the 11th letter of the Greek alphabet.
The language Unlambda is a functional programming language based upon combinatory logic, a simplification of the lambda calculus that does not involve the lambda at all, hence the un- prefix.

As more than a decade of research in the United States and the USSR had shown, sounding rockets could be used to attack problems of the atmosphere and ionosphere, the magnetosphere, solar physics and astronomy, cosmic rays and interplanetary physics, and biology.
During 1961 and 1962 NASA and the Italian Space Commission cooperated on a series of rocket firings in Sardinia to measure upper atmospheric winds by tracking glowing clouds of sodium vapor released at altitude from the rockets.
From these exploratory tests engineers had gone on to larger rockets, which were being flown from a launching pad at Akita on the western coast facing the Sea of Japan.

 Fabulous Adventures In Coding
We could immensely complicate the definite assignment rules by adding rules to discover which lambda and anonymous method bodies are guaranteed to be never called during the initialization, and therefore suppress definite assignment errors on some locals in their bodies.
But one of the goals of the standardization process is to make rules that are clear and unambiguous and comprehensible by mortals; enabling recursive anonymous methods isn't a big enough win for the amount of complexity, particularly when you consider that there is the simple workaround of assigning to null and then reassigning.
When a lambda expression is passed to a generic method we must infer the return type of the lambda from the set of expressions returned from its body:

 Military & Aerospace Electronics - Lambda introduces compact 960-watt modular AC-DC power supplies
Lambda in San Diego is introducing a series of power supplies that can supply as much as 960 watts, called the NV-700 series, which is suitable for high-density medical, industrial, and test-and-measurement equipment.
The power supplies are part of Lambda’s NV family of environmentally friendly AC-DC power supplies.
The NV-700 series is built on Lambda’s MRT (multiple resonant topology), which uses synchronous rectification to achieve the supply’s efficiency and reduce power loss.

Bumper 2 rockets carried small payloads that allowed them to measure attributes including air temperature and cosmic ray impacts.
Suggestions of a cosmological constant (lambda) are not new -- they have existed since the advent of modern relativistic cosmology.
Such claims are not usually popular with astronomers, though, because lambda is so unlike known universe components, because lambda's value appears limited by other observations, and because less-strange cosmologies without lambda have previously done well in explaining the data.

The value of that variable outside the lambda should be passed as an argument to the lambda, where another variable of the same name can be bound to it.
