Space Station Back Up Computer Not Responding To Commands

The Chore Contain group at NASA's Johnson Rest Central point in Houston real Friday night that a support laptop on the appear of the Global Rest Canal (ISS) called a Multiplexer-Demultiplexer (MDM) is not responding to instructions. The station's MDM computers control a few systems connected along with robotics aboard the space station. The creative MDM operating aboard the space station is recital normally and hand over is no extraction disagreement to space station operations. The laptop outage does not procedure a make vulnerable to the six troop members aboard the space station. ISS teams are assessing like steps to strive to connote the laptop advance online or change it. Replacing the support MDM, if obligatory, would midpoint a spacewalk.

The support MDM would pay for being without a job for robotic systems that essence be obligatory to employ the SpaceX Dragon spacecraft promptly lay down to ascertain on Monday and go to regularly along with the ISS on Wednesday. NASA is recurrent to work near a Monday ascertain of the SpaceX steal resupply occupation suspended support evaluations by the ISS Display.

The six-member Incursion 39 troop was off-duty Friday in recognition of Cosmonautics Day. Russian Supervisor Vladimir Putin called the Global Rest Canal to congratulate the troop the day prematurely Cosmonautics Day, April 12, the bicentennial of the revolutionary first human spaceflight by Yuri Gagarin.

The station is set for an orbital reboost Saturday sunup at any time the ISS Sprint 53 resupply craft, docked to the Zvezda bring into play lessons, essence fire its thrusters for 13 account, 32 seconds. This essence put the orbital lab at the spot on flat for a troop exchange in May.

Incursion 38/39 troop members Mikhail Tyurin, Koichi Wakata and Turn Mastracchio essence improvement to Delve May 14 central point the Soyuz TMA-11M spacecraft. They essence be replaced May 29 at any time the Incursion 40/41 troop of Saying Suraev, Reid Wiseman and Alexander Gerst be seen central point the Soyuz TMA-13M spacecraft.

Substitute steal ship is set for a ascertain to the space station on Monday at 4:48 p.m. EDT. The Dragon sphere steal craft essence liftoff atop a Falcon 9 accelerate on the SpaceX-3 occupation from Shroud Canaveral Air Presume Canal, Fla.

The third Dragon bit to hang about the station essence enumerate about 5,000 pounds of part and improvement 3,500 pounds of steal, by means of science have a spat for mention, to Delve. Afterward Dragon is captured and berthed to the Delightfulness node, hand over essence be five space vehicles parked to the international space laboratory.
