NASA was also responsible for the development and launching of a number of satellites with Earth applications, such as Landsat, a series of satellites designed to collect information on natural resources and other Earth features; communications satellites; and weather satellites. Research at NASA’s Goddard Institute for Space Studies (GISS) emphasizes a broad study of global change, which is an interdisciplinary initiative addressing natural and man-made changes in our environment that occur on various time scales – from one-time forcings such as volcanic explosions, to seasonal and annual effects such as El Niño, and on up to the millennia of ice ages – and that affect the habitability of our planet.

Jika konsentrasi bahan organik dalam tambak yang semakin tinggi, menyebabkan kualitas air/lingkungan hidup udang juga semakin menurun, akibatnya udang mudah mengalami stres, yang ditandai dengan tidak mau makan, kotor dan diam di sudut-sudut tambak, yang dapat menyebabkan terjadinya kanibalisme. So, will we ever know in our lifetime if it’s possible to deflect an asteroid? Maybe. In December 2009, the director of the Russian Federal Space Agency, Anatoly Perminov, announced that Russia was considering making plans to deflect the 270-meter (885-foot) asteroid Apophis from its possible collision course with Earth.

Lockheed Martin Space Systems. The company hopes the reusable mini-shuttle, which will launch via rocket and land like an airplane, will stake out a sizable plot of the space tourism and commerce real estate.

When one digs down one soon discovers that the market leading Adams MBD product is being used extensively for industrial grade co-simulations around the world today as a matter of course, and is open to connections with all sorts of commercial and open-source software (see Figure 2). Some notable recent innovations are connections to the market leading Discrete Element Modeling software, EDEM, from DEM Solutions, as illustrated by Figure 3, VIRES Virtual Test Drive (VTD) for ADAS and autonomous vehicle drive simulation (VIRES has been part of MSC/Hexagon since 2017), and of course MATLAB & SIMULINK for 0D/1D systems and controls modeling (from Math Works).

Take the Dream Chaser, Sierra Nevada’s planned commercial crew vehicle, which will ferry up to seven astronauts and cargo to and from the International Space Station. NASA funded the ship via its Commercial Crew Development program to the tune of $110 million. The larger diameter (16.5 feet, or 5 meters, instead of 3.9 feet) will hold more crew and cargo. The capsule will be cone-shaped like the Apollo command module, because it is more aerodynamic than the shuttle. But if there really are problems, we can expect to see more whistleblowing down the line. Those are the part that are most likely the contributing factor. While planets have previously been found in the habitable zone, they are all at least 40 percent larger in size than Earth and understanding their makeup is challenging. Apollo used four units of four thrusters mounted on the service module for this task, while the shuttle uses reaction control thrusters located on the nose and aft sections.

Although the space shuttle is still a technical marvel, the fleet is aging and has become increasingly expensive to operate.

Recent problems with foam insulation have exposed crews to danger, rendered it unsafe to fly, and caused NASA to ground the entire fleet. The resulting three breaches caused a leak resulting in a premature engine shutdown, when four external tank LO2 sensors flashed dry resulting in low-level cutoff of the main engines and a slightly early main engine cut-off with a 16 ft/s (4.9 m/s) underspeed, and an 8 nautical mile lower altitude. NASA tested four nuclear scenarios: a surface explosion, a delayed surface explosion, a subsurface explosion and a standoff explosion (where the bomb doesn’t come into contact with the asteroid). The asteroids that would be really worrisome — those larger than 1,312 feet (400 meters) — wouldn’t be easily wiped out by such a bomb. Meanwhile, the observatory continues its trek out to its station orbiting Earth-sun Lagrange point 2, or L2, which is located about 1 million miles (1.5 million kilometers) away from Earth on the side opposite the sun. And that creates the rains down in Saturn, with gravity winning out against orbital velocity.
