Houston to NASA Mainframe: You’re Through!

First the Space Shuttle, now the mainframe. It seems like NASA is doing away with the last vestiges of its swinging ’70s heyday, when TV astronauts were played by stars such as Farrah Fawcette. NASA pulled the plug on its last mainframe computer this month, an IBM Z9 mainframe at the Marshall Space Flight Center, NASA’s giant research facility near Huntsville, Alabama.

Next-Gen Spacesuits

ambermichelle writes “Outer space is a hostile environment for humans, characterized by an airless vacuum, thermal extremes, ionizing radiation and speeding micro meteoroids. Less well-known are the dangers posed by long-term exposure to microgravity or zero-g conditions, which over time severely saps the strength of astronauts’ muscles and bones. Several researchers are working to develop new spacesuit designs that could help counteract these threats as well as avoid some of the familiar drawbacks of current spacesuit models such as bulk, weight and rigidity.”

SpaceX Tries Out Its New SuperDraco Rocket Engine

cylonlover writes “SpaceX, the California company that is developing the reusable Dragon spacecraft, recently test-fired its new SuperDraco engine. Presently, the Dragon capsule is equipped with less-advanced Draco engines, which are designed for maneuvering the spacecraft while in orbit and during reentry. The SuperDraco, however, is intended to allow the astronauts to escape if an emergency occurs during the launch.”

What If the Apollo Program Never Happened?

astroengine writes “In a recent debate, Republican presidential candidate Newt Gingrich said he would like to beat the Chinese back to the moon. He has even been so bold as to propose setting up a manned base by 2020, driven by empowering private industry to take the initiative. It’s ironic to hear moon travel still being debated 40 years after the last Apollo landing in 1972. Between then and now, NASA’s small space shuttle fleet filled in for space travel, but astronauts could only venture as far a low earth orbit — at an altitude much lower than the early pioneers reached. If there were no Apollo crash program to beat the Soviets to the moon, would we have planned to go to the moon eventually? But this time with a commitment of staying? Or would we never go?”

Mars-Bound Probe Serves As Radiation Guinea Pig

sighted writes “This week’s huge solar storm will benefit future astronauts, thanks to the rover Curiosity, now on its way to Mars. The rover is equipped with an instrument that measures the radiation exposure that could affect a human astronaut en route to the Red Planet. Scientists are just starting to pore over the data from the blast of particles. Don’t worry about the poor robotic geologist, though: ‘No harmful effects to the Mars Science Laboratory have been detected from this solar event,’ says NASA.”
