NASA restarted a two-day dress-rehearsal countdown Tuesday for the agency's new Space Launch System moon rocket after a series of unrelated glitches, mostly involving ground systems, blocked two earlier attempts to fully fuel the huge launcher to verify its readiness for flight.
A problem with a helium valve on the Space Launch System moon rocket's upper stage will require ground teams to only partially load the giant launcher with cryogenic propellants during an upcoming countdown dress rehearsal, NASA officials said Saturday. NASA also confirmed teams now targeting Thursday for the next try to complete the test.
NASA officials said Tuesday they are standing down from a cryogenic loading test on the agency's Space Launch System moon rocket until after the launch of a commercial crew mission from a neighboring pad at the Kennedy Space Center. A countdown test Monday was delayed by what NASA managers characterized as minor issues, including a liquid oxygen temperature concern and a manual valve that was left in the wrong configuration before teams evacuated the SLS launch pad.
This timeline covers major countdown activities planned during the NASA's wet dress rehearsal for the Artemis 1 mission. The wet dress rehearsal will include loading of more than 700,000 gallons of cryogenic liquid hydrogen and liquid oxygen into the Space Launch System moon rocket on launch pad 39B at the Kennedy Space Center in Florida.

So far, four packages of sanctions have been approved at the EU level against Russia in response to the attack on Ukraine. What is less well known, however, is that some of the sanctions were already imposed after Russia’s […]
