Probe on Mars, astronauts on the Moon... Why China is so keen to win the space race

On Wednesday 10 February, the Tianwen-1 probe arrived in Mars orbit. A new stage in China's conquest of space, analysed on The Conversation.

All eyes on the stars. NASA's Perseverance mission landed on the Red Planet on Thursday 18 February. It is the third mission to arrive on Mars in a week, along with those from the United Arab Emirates and China. The Tianwen-1 probe arrived in the planet's orbit on 10 February. In the spring, it is due to land a remote-controlled wheeled robot on the Martian surface. This mission will enable Beijing to pursue its ambitions for space conquest, which began under Mao sixty years ago. The country "dreams of space", in the words of Chinese President Xi Jinping. For The Conversation, Steffi Paladini, from the University of Birmingham, deciphers these dreams. 

Given its achievements over the last decade, it's only logical that China should be looking to win the new space race. Not only has it been the only country to send a probe to the Moon in the last forty years or so - and the first in history to successfully land on its far side - but it has also planted a flag on lunar soil and brought samples back to Earth.

However, the space race, in which several nations and private companies are taking part, is far from over. China is now turning its attention to Mars with its Tianwen-1 mission, which arrived in Martian orbit on 10 February. This successful insertion into orbit - the rover will not land until May - marks a crucial new stage in more ways than one.

Even though Mars is relatively close to Earth, it's a tough target to hit. Nothing demonstrates this better than the figures. Out of 49 missions up to December 2020, only around 20 have been successful. Not all of these failures were the result of novices or first attempts. In 2016, the European Space Agency's Schiaparelli Mars Explorer crashed on the surface of the Red Planet. In addition, persistent technical problems have forced ESA and its Russian partner Roscosmos to postpone its next mission, ExoMars, until 2022.

China is not the only country to get close to Mars. On 9 February, a probe from the United Arab Emirates, Hope, successfully completed the same insertion manoeuvre. It is not a direct competitor of the Chinese mission (the probe will only orbit the planet to study the Martian weather), but NASA's Perseverance rover, which arrived a week later, is undoubtedly.

One factor makes the stakes even higher for Beijing: one of the few countries to have successfully performed the famous in-orbit insertion manoeuvre is India, China's direct competitor not only in space but also on Earth.

India's Mars Orbiter Mission (MOM), aka Mangalyaan, reached Mars in 2014 - it was the first to achieve this feat on its inaugural mission. This is one of the reasons why the success of Tianwen-1 is so important for China's status as an emerging space power: it's a way of reasserting its space dominance over its neighbour. Unlike India, this is not the first time China has attempted a mission to Mars (the previous one, Yinghuo-1, in 2011, failed on launch). This time, however, the chances of success look much better.

The space age 2.0

Different countries have different space development models. The new space race is therefore partly a competition for the best approach. This reflects the specific character of the Space Age 2.0, which, compared with the first, seems to be more diversified and where non-American players, both public and private, occupy an important place, particularly Asian players. If China is leading the pack, so too is its vision.

But there are more important issues at stake. The development of China's space sector is still largely government-funded and military-led. According to the US-China Economic and Security Review Commission, a US congressional committee, China sees space as a "tool for geopolitical and diplomatic competition". Clearly, with cyberspace, the cosmos has become a fundamental new battleground, where the United States is the main - but not the only - adversary. This means that commercial considerations are taking a back seat for many countries, even if they are becoming increasingly important as a general rule.

China has already adopted five-year plans for its space activities. The most recent ended in 2020 with more than 140 launches. Other missions are planned, including a new orbital space station, the recovery of Mars samples and a mission to explore Jupiter.

While the resources committed by the country remain largely unknown (we only know what is included in the five-year plans), US estimates for 2017 are $11 billion, putting China second only to the US itself - NASA's budget for the same year was around $20 billion.

India has adopted a different approach, where civil and commercial interests predominate. Following NASA's model of transparency, the country publishes reports on the activities and annual expenditure (around US$1 billion a year) of its space agency, the Indian Space Research Organisation (ISRO).

Different in ambition, scope and investment, India's space programme has achieved remarkable successes, such as the commercialisation of affordable launch services for countries wishing to send their own satellites into orbit. In 2017, India made history with the most satellites - 104 - ever launched by a rocket on a single mission to date (all but three were foreign-built and foreign-owned). This record was broken by SpaceX in January 2021, with 143 satellites. Even more impressive is the relatively low cost of India's Mars mission, 74 million US dollars - around ten times cheaper than NASA's Maven mission. Indian Prime Minister Narendra Modi said the entire mission cost less than the Hollywood film Gravity.

For geopolitical reasons, this could soon change. The Indian government has published its 2019-2020 annual report, which shows growing military involvement in the space sector. And further missions to the Moon and Venus are planned by India's ISRO, as if to further motivate the Chinese to make Tianwen-1 a resounding success.

Coronavirus: Dubai, Cuba and Florida take up the challenge of "vaccine tourism

LIGHTNING - Some travel agencies are no longer hesitating to offer "all-inclusive" holidays.

How about basking in the sun, cocktail in hand, between two doses of vaccine? In any case, the concept of "vaccine tourism" seems to be spreading more and more. While Europe shudders at the thought of a shortage, some countries are not hesitating to offer the injection under the coconut trees. 

"Caribbean, mojito and vaccine"... This advert has been on air since Cuba to the whole of South America. From next March, tourists staying three weeks on the island will be entitled to Cuban vaccines, as announced by the authorities in this short publicity film, between two beach photos: " Tourists have the option of being vaccinated in Cuba if they so wish". 

Not far from there, in FloridaIn Florida, it's the neighbours to the north, Quebecers over 65, who can register to be vaccinated. They don't have to be residents or own property in Florida. A proposal that irritates many Americans. 

And then there is the exceptional case of the very rich of Britons over 65Those who belong to a very closed London circle. For a fee of 45,000 euros, they are invited to live in Dubai for a month, including first-class or private jet travel, reserved villas and double-dose vaccinations.

In Martigues, 97 fines during the OM-PSG match in a bar

In the middle of a curfew, 97 people gathered in a chicha bar in Martigues (Bouches-du-Rhône) without respecting the health instructions against Covid-19.

COUVRE-FEU - It was an evening that cost them dearly. On Sunday 8 February, 97 people gathered in a shisha bar in Martigues (Bouches-du-Rhône) to watch OM-PSG in the middle of a curfew and without respecting health regulations were fined, the police announced. 

All received a fine (135 euros) or a double fine (270 euros) for not wearing a mask and not complying with the curfew, the Direction départementale de la sécurité publique (DDSP) told AFP. "There was no respect for distances. It was completely unreasonable, just nonsense", commented the DDSP. 

The number of tickets issued has increased in recent weeks in France as part of a drive to enforce the curfew. At the beginning of February, for example, in the Val-de-Marne region of Paris, the police issued 133 fines for breaching the curfew after a clandestine party attended by 80 people. 

A total of 177,000 fines have been imposed since the 6 p.m. curfew was introduced on Saturday 16 January, announced Interior Minister Gérald Darmanin at a press briefing on Thursday 4 February to review the health situation in France. 

In detail, "the number of these checks increased by 39% last weekend compared with the previous weekend", said the Minister, who assured us that these checks would continue to "intensify". The number of fines imposed "increased by 53%". 

Gérald Darmanin also said that he had "asked the police to be particularly vigilant about clandestine parties and restaurants".

The Starship exploded again on landing, but SpaceX is optimistic

SpaceX has flown another prototype of its future Starship rocket. Although most of the test went well, the landing was missed again. The SN9 rocket ended its career in a spectacular explosion.

Bis repetita for Starship. On Tuesday 2 February, the prototype of SpaceX's future rocket was tested again. This was the ninth example of the vehicle (SN9, for Serial Number 9) to be tested in this way. The aim? To perform a high-altitude "jump", execute complex manoeuvres, test a sequence of ignition and extinction of the engines, then return smoothly to terra firma.

In short, the aim was to reproduce the SN8 test, which took place on 9 December, but with the hope of a different outcome. With the SN8, everything went very well, except on landing: a pressure problem in one of the tanks prevented it from having enough thrust to decelerate sufficiently on return. The result: the SN8 hit the ground too quickly, causing its destruction.

One of the engines failed to restart

Unfortunately, SpaceX didn't manage to write a different ending with SN9. Or to be more precise, it did, but not the one the American company had hoped for. Once again, SN9 ended its career in a huge fireball. Except that this time, the problem that caused the prototype's destruction was not a pressure problem, but an engine incident: one of the three used during the test failed to relight.

During the tilt-landing manoeuvre, one of the Raptor's engines failed to restart, causing the SN9 to land at high speed and suffer a RUD. "SpaceX explains. A RUD, an acronym for Rapid Unscheduled Disassembly, or Rapid Unplanned Disassembly, is an elegant term and a euphemism for saying that it exploded.

For those who followed the flight live on 2 February, which lasted around a quarter of an hour in all, the SN9's fatal outcome could have been anticipated just beforehand by the fact that the prototype was leaning far too far and arriving far too fast at its landing site for it to go well. In these conditions, it was impossible to land smoothly and correctly on its landing gear.

As with SN8, the SN9 test will undoubtedly be remembered for its fiery conclusion. However, it should be noted that all the previous stages clearly went well: the ascent to an altitude of around ten kilometres, the programmed and sequential shutdown of the engines, the flip onto its side and its return to the launch pad.

The SN9 was propelled during the climb by three Raptor engines, each stopping in sequence before the vehicle reached its apogee. "comments SpaceX. " SN9 successfully made a propulsion transition to the internal manifold tanks, which contain the landing propellant, before reorienting itself for a controlled aerodynamic re-entry and descent. "adds the company.

For SpaceX, the question now is how to overcome the landing hurdle, which is clearly its current weakness with the Starship prototype. The SN10 model will be the next to try its luck. Further tests are expected in 2021. And if all goes well, it's possible that an inaugural Starship flight could take place as early as November. Unless the crashes persist.
