NASA’s Voyager 2 is Back

Sunday, May 30th, 2010

NASA’s Voyager 2 space probe experienced communication problems on April 22th that scrambled the messages the probe sent back. That problem has now been fixed. A single corrupted peice in it’s memory system caused the issue, which has been resolved when NASA’s Jet Propulsion Laboratory resetted space probe’s memory.

The space probe is flying 13.8 billion km (8.6 billion miles) from Earth in the helisophere, the magnetic bubble that surrounds our solar system. The cause of the glitch is unknown. Memory bit flips have affected other space craft, including voyager 1 & 2 in the past, though much closer to earth. The problems are geneally caused due to solar activity, but with the space craft so far away, it’s hard to say what exactly caused the issue. The two Voyager probes are the farthest human-built objects from Earth. Voyager 1 is 16.9 billion kb from earth. Messages from the space craft take about 13 hours to travel back to Earth.

Atlantis Arrives at Space Station

Sunday, May 16th, 2010

The space shuttle Atalantis has docked to the International Space Station. Before docking, a snagged cable prevented astronauts from doing a proper inspection of the shuttle. A cable on Atlantis’ inspection boom is caught in a camera. The problem prevented the astronauts from thoroughly checking the left wing and some other areas of the spacecraft Saturday. As a result, the shuttle did a slow backflip as space station crew took pictures of the space shuttle for safety reasons. This is NASA’s last planned flight for Atlantis. Only two more shuttle missions remain before the fleet is retired, then the US will rely on Russian spacecraft for missions–a move that has angered many in the U.S.

NASA Tests Abort System for the Orion Capsule

Thursday, May 6th, 2010

NASA has successfully tested the launch abort system for its new Orion crew capsule. However, President Obama has now stated Orion will never be launched with crew aboard. President Obama has recently cancelled the Ares I rocket, which was to be used with the Orion capsule. He originally axed the Orion too, but switched course saying that it might be sent into space unmanned for attachment to the International Space Station to replace the Soyuz capsule as the space station’s emergency escape vehicle.

Obama’s Plan for NASA

Thursday, May 6th, 2010

Three weeks after Obama told an audience at Kennedy Space Center that he wants to land astronauts on an asteroid by 2025, Congress, NASA, and the American public remains unconvinced. Under the Bush administration, NASA was scheduled to return to the moon to test new equipment before going to Mars. After canceling the space shuttle and new rocket designs, the Obama administration has decided to go for somewhat different goals: An Asteroid. Recently, the administration called for the cancellation of the constellation program, which would have wasted billions of dollars of tax player money. The government has famously canceled multi-billion dollar research projects more than three quarters completed, including a nuclear power plant that would have trans-mutated nuclear waste into usable fuel.

The moon has been visited, but why not anymore? The new goal appears to be an asteroid that is orbiting earth. (Remember the movie Armageddon?) The update of plan comes with a push for private industries to compete for contracts.  The space capsule, a part of the Ares rocket program, would now be used as an emergency escape module for the International Space Station.  After an asteroid, landing people in Mars will become a priority.

So much for the George W. Bush administration’s goal to visit the moon and build a permanent lunar base there.

The most controversial part of the president’s policy is the cancellation of the Constellation program, which was aimed at developing a new generation of Ares rockets and Orion spacecraft to send astronauts into Earth orbit and beyond. NASA itself also appears to be hedging its bets that the president’s vision might not pass muster with Congress. KSC officials and contractors, under direction from Johnson Space Center and NASA Administrator Charlie Bolden, are pressing ahead with plans for test flights of a multibillion-dollar Ares I rocket that Obama wants to cancel.
