investigations into the accuracy of some pcr tests have singled out a private lab on this science park in wolverhampton. testing on site has been suspended. the precise cause is still being investigated but public health officials say other labs and test kits are unaffected. they have helped us as a surge facility, from the autumn and winter period, so we have had very good working relationships and they have supported the response. on this particular occasion, clearly there is a problem and therefore we have taken action immediately to suspend those services. nhs test and trace carries out about 800,000 pcr tests a day. it is estimated 43,000 people may have been given inaccurate negative pcr results from the wolverhampton lab between the 8th of september and the 12th of october. the problem mostly affects

London, June 13 : US space agency NASA has assembled the first of its powerful Space Launch System (SLS) rockets, which aims to return astronauts to the Moon.
The engineers at Florida s Kennedy Space Center have finished lowering the 65m tall core stage in between two smaller booster rockets, the BBC reported on Saturday.
It is the first time all three key elements of the rocket have been together in their launch configuration, the report said.
The SLS, which is part of the agency s Artemis programme that will carry humans to the Moon this decade, will be launched later this year.
Terminal operators in the Port of Long Beach have begun using the Pier S overflow facility to provide temporary storage for rail containers that would otherwise be stuck inside active marine terminals and contributing to congestion at Southern California port complex.
NASA s SLS rocket faces new setback that could delay astronauts return to the moon
Less than a minute into a recent test, the SLS engine experienced a major component failure – a considerable setback in the rocket s developmental timeline.

After billions of dollars and a decade of work, NASA’s plans to send astronauts back to the moon had a new setback Saturday. A planned eight-minute test firing of the four engines of a new mega rocket needed for the moon missions came to an abrupt end after only about a minute. As engineers disentangle what went wrong, the first launch of the rocket is likely to slip further into the future, and NASA astronauts may have to wait longer before setting foot on the moon again. NASA officials, however, said that it was too early to predict delays, if any.
SLS, Stennis working on colder LOX for next Green Run WDR attempt
December 11, 2020
Space Launch System (SLS) Core Stage Green Run team members are working on new procedures to supply liquid oxygen (LOX) to the vehicle at lower temperatures in the next Wet Dress Rehearsal (WDR) attempt. The first attempt on December 7 at the Stennis Space Center in Mississippi was scrubbed because the temperature of the LOX was a few degrees higher than design requirements as it entered the vehicle; NASA did not want to continue loading with the temperature out of limits.
The problem is not with the Core Stage itself; engineers with the SLS Program, Core Stage prime contractor Boeing, and NASA Stennis are looking at ways to reduce the temperature of the cryogenic liquid before it reaches the stage from barges docked next to the B-2 Test Stand. In the meantime, the test team is recycling the stage and other equipment to be ready to start a new Wet Dress Rehearsal attempt no earlier than the week of
