James Webb Space telescope is facing technical issues

MRS observations by the $10 billion instrument have been paused

A problem with one of the instruments on Nasa’s $10 billion James Webb Space Telescope has caused the space agency to pause one of its means of making observations.

Nasa announced on Wednesday that a mechanism on the observatory’s mid-infrared instrument, or MIRI, was experiencing technical issues.

Scientists use four modes on this mechanism to see further into space, but one that supports medium-resolution spectroscopy, or MRS, is facing issues.

The space agency said that there was increased friction in the mode during set-up for a science observation.

“Following preliminary health checks and investigations into the issue, an anomaly review board was convened on September 6 to assess the best path forward,” it said.

“The Webb team has paused in scheduling observations using this particular observing mode while they continue to analyse its behaviour and are currently developing strategies to resume MRS observations as soon as possible.”

The space agency said that the telescope was in “good health” and that MIRI’s other three observing modes — imaging, low-resolution spectroscopy and coronagraphy — were operating normally.

Observations by the MRS allows scientists to select between short, medium and longer wavelengths.

This is a crucial element in the telescope, which has enabled scientists to make discoveries and deliver stunning pictures of the universe.

The world’s most powerful observatory was launched into space on Christmas Day, 2021, to look back at the galaxies formed shortly after the Big Bang, almost 13.8 billion years ago.

It was developed along with the European and Canadian space agencies.

Ziina users can donate to relief efforts in Beirut

Ziina users will be able to use the app to help relief efforts in Beirut, which has been left reeling after an August blast caused an estimated $15 billion in damage and left thousands homeless. Ziina has partnered with the United Nations High Commissioner for Refugees to raise money for the Lebanese capital, co-founder Faisal Toukan says. “As of October 1, the UNHCR has the first certified badge on Ziina and is automatically part of user's top friends' list during this campaign. Users can now donate any amount to the Beirut relief with two clicks. The money raised will go towards rebuilding houses for the families that were impacted by the explosion.”

Why it pays to compare

A comparison of sending Dh20,000 from the UAE using two different routes at the same time - the first direct from a UAE bank to a bank in Germany, and the second from the same UAE bank via an online platform to Germany - found key differences in cost and speed. The transfers were both initiated on January 30.

Route 1: bank transfer

The UAE bank charged Dh152.25 for the Dh20,000 transfer. On top of that, their exchange rate margin added a difference of around Dh415, compared with the mid-market rate.

Total cost: Dh567.25 - around 2.9 per cent of the total amount

Total received: €4,670.30 

Route 2: online platform

The UAE bank’s charge for sending Dh20,000 to a UK dirham-denominated account was Dh2.10. The exchange rate margin cost was Dh60, plus a Dh12 fee.

Total cost: Dh74.10, around 0.4 per cent of the transaction

Total received: €4,756

The UAE bank transfer was far quicker – around two to three working days, while the online platform took around four to five days, but was considerably cheaper. In the online platform transfer, the funds were also exposed to currency risk during the period it took for them to arrive.
