CEMAC zone: recession could reach 6% according to BEAC

All the indicators are certainly not red. But most of the economic indicators in the six countries of the Economic and Monetary Community of Central Africa (CEMAC) are already found the Monetary Policy Committee (CPM) of the Bank of Central African States (BEAC) at the end of the second annual session on June 24, 2020 in Yaoundé.

Analyzing the situation in Central Africa, it emerges that in the short and medium terms, the CEMAC zone is affected by the health crisis and the fall in the prices of the main export products. "

"In the first half of 2020, the revival of productive activities was slowed down in the sub-region by the disruption of supply circuits for imported products as well as by the restrictive measures adopted by the various governments to contain the effects of the pandemic. Although it is premature for the moment to fully grasp the impact of COVID-19 on national economies, it is already anticipated during this first semester a drop in production as well as a det…

NASA: Boeing is a problem, Voyager 2 too

Not everything has been going well lately, for NASA. First, the United States Aerospace Agency recently released its report on the test flight of the Boeing travel pod and it is not famous. Second, for almost a year, its astronomers will be unable to communicate with the Voyager 2 probe, which is delivered to itself beyond the solar system.

NASA: Boeing is a problem, Voyager 2 too

Not everything always works perfectly for the largest aerospace agency in the world. The American Aerospace Agency (NASA) has a lot of work to do before reconquering the Moon and preparing for its first manned flight on Mars. Pending this, she is currently experiencing two problems. The first could impact the organization of its space flights in the future. To emancipate itself from the Russian Soyuz spacecraft, NASA has entrusted two private American companies to design and then conduct its astronauts in space in the future: SpaceX and Boeing. These last two should allow NASA to finish regaining its independence and to materialize its flight plans to our natural satellite.

However, unlike Elon Musk's company, Boeing is not in a position to transport astronauts to or from the International Space Station. Last December, the airline tested its CST-100 Starliner vacuum capsule to assess whether it was capable of landing the ISS without a hitch. Several technical concerns disturbed the maneuver and made this test a failure. After three months of investigation, NASA released its report: it identified 61 different pitfalls to be corrected by Boeing. Among them, NASA notably identified a timing problem with one of the software managing certain thrusters according to The Verge. According to the Agency, these technical problems could have been identified before the test flight. NASA has reportedly rated 49 points that Boeing should have addressed before the test took place. Boeing engineers “must now return to NASA with a new proposal and solutions,” said Doug Loverro, associate administrator for NASA space flights. Otherwise, NASA may decide to separate from Boeing.

The second problem that NASA is currently facing should certainly have less impact on its activities, but could affect its research. In November 2019, the Voyager 2 space probe became the second human object to exit the solar system. It is located today more than 18.5 billion km from our planet and aims to inform us about the interstellar world, beyond our simple Sun. Unlike its “big sister”, Voyager 1, it still has measuring instruments in perfect working order and can communicate without problems with earth engineers. The only problem is that in order for the latter to send it commands, they have to go through just one type of long distance radio wave. Called the S-band, this frequency band can only be transmitted from a limited number of satellite dishes. There are only three in the world: one in California, one in Spain and one in Australia. Given Voyager 2's position in the cosmos, NASA can only use the one in Australia. This Australian radio antenna, DSS43, is over forty years old and in serious need of a break. An overhaul of its IT infrastructure and some physical work to correct some things and modernize others will be carried out during the next eleven months. Consequently, during this period, Earth will have no way of sending commands to the Voyager 2 probe, for example to change its trajectory and prevent it from having an accident en route. NASA will still be able to receive data from the probe, but the latter's fate is now in the hands of chance.
