He is also an Eagle Scout (yes, he has the Space Exploration merit badge) and went to Space Camp four times as a kid and a fifth time as an adult. In October 2022, Tariq received the Harry Kolcum Award for excellence in space reporting from the National Space Club Florida Committee. Before joining, Tariq was a staff reporter for The Los Angeles Times covering education and city beats in La Habra, Fullerton and Huntington Beach. He became 's Managing Editor in 2009 and Editor-in-Chief in 2019. He covers human spaceflight, exploration and space science, as well as skywatching and entertainment. Tariq is the Editor-in-Chief of and joined the team in 2001, first as an intern and staff writer, and later as an editor. Fixing NASA: Complete Coverage of Space Shuttle Return to Flight."But we've all agreed this work is doable, and thatit all takes us to a launch." "We've got a great amount of work infront of us," Parson said. Additional dates for the flight - should itfail to fly Tuesday - include the 27 th, 29 th and 31 stof July. Launch officials said that ifnothing bars a July 26 space shot, flight controllers should have at least fouropportunities to launch Discovery. Still more daylight is needed during Discovery's InternationalSpace Station (ISS) rendezvous, where station crewmembers will photograph itstile-lined belly to record and transmit its condition to ground-basedengineers.Ĭolumbia disintegrated duringatmospheric reentry, killing its seven-astronaut crew, on Feb. New launch protocols institutedafter the Columbia accident call for optimum lighting levels for the myriad ofstill and video cameras watching the shuttle's ascent, as well as good lightingfor the STS-114 crew when they photograph the external tank just after itseparates from the orbiter. If shuttle officials see a sensorfailure that they do not expect then they'd have to reassess the situation,which could take more than 24 hours or push the launch outside of July entirely, Parsons added.ĭiscovery's launch window runsthrough July 31, with the next flight opportunity opening on Sept. "If we can understand that failure and it was a knownfailure that we expected.then we might very well be willing to go fly withthree of four sensors, there's good flight rationale behind it." "We expect to have four of foursensors," Parsons said. While all four hydrogen ECO sensorsare required to perform properly under current flight rules, shuttle officialssaid they could make an "exception" for Discovery on launch day if they see aglitch that they fully understand. "We'd absolutelyhave to be out of there by then." "About 20 hours into the countdownis when you do the cryogenic loading for the fuel cells," saidMichael Wetmore, director of space shuttle processing at KSC. EDT (1600 GMT) Saturday, Parson said.īut engineers have only a limitedtime to complete their troubleshooting efforts inside Discovery's aftcompartment, where the electronics box that processes ECO sensor readingsresides. ![]() Additional tests over the next 48 hoursshould address those areas, with the launch countdown set to begin at about12:00 p.m. Shuttle engineers investigatingthe anomaly believe that electromagnetic interference from existing or newhardware, such as additional cameras or heaters attached to the bipod fittingthat connects Discovery to its external tank, and a small grounding issue withsensor wiring may be the culprit.
