China launches independent, unmanned Mars mission

first_imgIf successful, the Tianwen-1, or “Questions to Heaven”, which is the name of a poem written two millennia ago, will make China the first country to orbit, land and deploy a rover in its inaugural mission.There will be challenges ahead as the craft nears Mars, Liu Tongjie, spokesman for the mission, told reporters ahead of the launch.”When arriving in the vicinity of Mars, it is very critical to decelerate,” he said.”If the deceleration process is not right, or if flight precision is not sufficient, the probe would not be captured by Mars,” he said, referring to gravity on Mars taking the craft down to the surface. Topics : Liu said the probe would orbit Mars for about two and a half months and look for an opportunity to enter its atmosphere and make a soft landing.”Entering, deceleration and landing (EDL) is a very difficult (process). We believe China’s EDL process can still be successful, and the spacecraft can land safely,” Liu said.Eight spacecraft – American, European and Indian – are either orbiting Mars or on its surface with other missions underway or planned.The United Arab Emirates launched a mission to Mars on Monday, an orbiter that will study the planet’s atmosphere.The United States has plans to send a probe in coming months that will deploy a rover called Perseverance, the biggest, heaviest, most advanced vehicle sent to the Red Planet by the National Aeronautics and Space Administration (NASA).China’s probe will carry several scientific instruments to observe the planet’s atmosphere and surface, searching for signs of water and ice.China previously made a Mars bid in 2011 with Russia, but the Russian spacecraft carrying the probe failed to exit the Earth’s orbit and disintegrated over the Pacific Ocean.A fourth planned launch for Mars, the EU-Russian ExoMars, was postponed for two years due to the coronavirus pandemic and technical issues. center_img China successfully launched an unmanned probe to Mars on Thursday in its first independent mission to another planet, a bid for global leadership in space and a display of its technological prowess and ambition.China’s largest carrier rocket, the Long March 5 Y-4, blasted off with the probe at 12:41 p.m. (0441 GMT) from Wenchang Space Launch Centre on the southern island of Hainan.The probe is expected to reach Mars in February where it will attempt to deploy a rover to explore the planet for 90 days.last_img read more

Adaptability will be key to India’s success: Dhoni

first_imgSydney, Feb 7: Indian skipper Mahendra Singh Dhoni on Saturday said adaptability will be the key to success for the defending champions in the cricket World Cup starting on Feb 14.“What is important is to adapt to the conditions and the middle overs. Bowling in the middle overs will also be crucial because that will put pressure on the opposition which will put a cap on the scoring from the 35th over onwards and the slog,” Dhoni said on Saturday.“We haven’t had much opportunity to bowl in the slog overs which is something that will come into action when the World Cup starts.”Dhoni said his team is willing to change the batting order depending on the playing conditions, a prominent feature of the adaptability which he wants his team to have.“We have to alter out batting order according to the conditions. Wickets in hands is our strength and once we have wickets in hand we can really exploit the conditions,” he said.“We are not that deep when it comes to batting and are different to other teams. You have to pick options and learn to score runs freely.”The build–up to the quadrennial event has not been easy for India. They failed to win a single game in a tour off Australia that consisted of four Test matches and an ODI tri–series also involving England.However, Dhoni insisted that they are looking forward to the warm–up games to identify the players that are likely to feature in the team for the event.“Even while playing the Champions trophy, we were going through a rough patch. But, the guys stepped up during that tourment and we played very consistently which counts.We will use the two warm–up games to settle with the playing eleven that will feature in the first game. The warm–ups will be crucial from the perspective of what we want to achieve out of it,” added Dhoni.The defending champions will play their first warm–up game against Australia Sunday, before taking on Afghanistan in another tune–up game. They will start their World Cup campaign Feb 15 in a high–voltage match against Pakistan in Adelaide. IANSlast_img read more

Exporting SA geranium oil

first_img21 May 2003The geranium, historically one of South Africa’s earliest exports, is once more bringing trade to the country. In a landmark deal for SA’s budding bio-extract industry, half a ton of essential oil extracted from geraniums organically grown in South Africa has been exported to a major international cosmetics brand.Biosys Plant Extracts (BPE), formed by the Council for Scientific and Industrial Research (CSIR) and part-owned by British company Biosys Ltd, announced this week that it had secured the export order, BPE’s biggest deal so far, from a US-based cosmetics company. BPE MD Robin Learmonth told the SA Press Association (Sapa) that his company was confident that South Africa had the capability to produce a wide range of high-quality, international standard oils and to become a major player in the US$5-billion a year global essential oils market.BPE plans to buy essential oils from community-driven projects on the same terms as from commercial farmers, Learmonth told Sapa. “Today we are working with a diverse grower platform, with farmers producing from George in the south-eastern Cape to as far north as Malawi.“The new company, through the sales and marketing activities of its international owner, is building long-term sustainable markets for its plant products, a critical requirement for farmers looking to invest in this dynamic sector.”Essential oils are used in the production of expensive perfumes and personal healthcare products, as well as by the food and aromatherapy industries.Learmonth said he believed that the export of essential oils from South Africa would treble within two years.According to Business Day, the CSIR, which developed the proprietary technology being used by BPE’s producers to extract the essential oil from leaves and flowers, will be paid a percentage on BPE sales over the next 10 years, as well as a fixed fee for each distillation plant built.Geraniums (genus Pelargonium), aptly described as living potpourri for the home, are not grown for their flowers but for their scent. They are almost entirely native to South Africa, and became popular with Victorians when colonists brought them back to Britain. The French began commercial production of geranium oil in the early 19th reporterlast_img read more

Inzaghi on Lazios players and returning to winning ways

first_imgSimone Inzaghi has confirmed the unavailability of Luis Alberto and Lucas Leiva ahead of Lazio’s trip to Chievo and further claimed they are keen on returning to winning ways.“It’s never nice to lose, but I had taken into account that it could happen,” the Coach revealed to Football Italia after Thursday’s 2-0 Europa League defeat to Apollon Limassol.“To be honest, we had our minds on Chievo from the day after the Milan draw. Chievo deserved their draw with Napoli last week, Domenico Di Carlo has organised the team and they’ll allow very few spaces.SS Lazio v AS Roma - TIM CupMatch Preview: SS Lazio vs AS Roma Boro Tanchev – August 31, 2019 Lazio will host Roma to the Olimpico Stadium in the first Derby della Capitale of the 2019-20 Serie A campaign.“There will be many dangers in this fixture and we need a real Lazio performance.“Luis Alberto, Lucas Leiva, and Jordao are unavailable. Luis Alberto is generous and wanted to be there, but since the Milan game he’s been struggling with a groin injury and over the last few days he just hasn’t looked like he’s been running freely. It’s best he is rested and prepare to face Sampdoria.”last_img read more
