The next few weeks in February will bring nail-biting moments of truth for three countries — indeed, the world — as three separate Mars missions approach the Red Planet. The United Arab Emirates, China and the United States each launched separate missions to Mars in July 2020, and they are all about to arrive. The first two, within days of each other.
First Up: The Emirates Mars Mission<p>The <a href="https://www.dw.com/en/whats-the-science-on-the-emirates-mars-mission/a-53857637" target="_blank">Emirates Mars Mission</a> launched a probe called Hope on July 20, 2020, from Tanegashima Space Centre, Japan.</p><p>Hope is the first Arab interplanetary mission. It aims to provide scientists with a complete picture of the Martian atmosphere. And they promise to share the data.</p><p>On February 9, 2021, Hope will begin what's called a <a href="https://www.emiratesmarsmission.ae/journey/mars-orbit-insertion/" target="_blank">Mars Orbit Insertion</a> (MOI).</p><p>The so-called "burn" will commence at 7.30 p.m. Gulf Standard Time (4.30 p.m. CET, 10.30 a.m. EST), and will last "a rather nerve-wracking 27 minutes," in the words of one EMM spokesperson.</p>
Second: Tianwen-1<p>Next up, it's China with the country's first independent Mars mission. It was launched on July 23, 2020, from the Wenchang Space Launch Center in Hainan province.</p><p><a href="https://www.dw.com/en/the-facts-on-tianwen-1-mars-orbiter-and-rover/a-54014414" target="_blank" rel="noopener noreferrer">Tianwen-1</a> is also expected to enter a Martian orbit during the second week of February. In fact, it's hoped the Chinese robotic probe will make it the day after the EMM — and two days before the Chinese New Year.</p>
Third: Perseverance and Ingenuity<p>The <a href="https://mars.nasa.gov/mars2020/mission/overview/" target="_blank">USA's latest Mars mission</a> involves a new rover called Perseverance and a helicopter called Ingenuity. Ingenuity is strapped to the belly of the rover.</p><p>The rover is due to land on February 18 at about 3.55 p.m. EST at a place called Jezero Crater.</p><p>It will descend through the Martian atmosphere at a speed of about 20,000 kilometers per hour/kph (12,000 miles per hour). It will be slowed with a parachute and a powered descent to about 3.2 kph.</p>
NASA's Mars 2020 may pave the way for human missions to Mars.<p>Then, a large sky crane will <a href="https://www.dw.com/en/the-facts-on-perseverance-mars-2020-rover/a-54014387" target="_blank">lower the rover</a> on three bridle cords until it lands softly on six wheels.</p><p>That's the plan, anyway. NASA has landed a number of rovers on Mars over the years, but as it says itself: "Landing on Mars is hard."</p>
Race to the Red Planet<p>NASA describes Perseverance as a "robotic astrobiologist." It is the largest and "most sophisticated" rover ever sent to the Red Planet's surface.</p><p>Perseverance will look for signs of ancient Martian life. It will also demonstrate technologies for making oxygen from the Martian atmosphere. It is hoped the mission will prepare the ground for future human missions to Mars and our moon.</p><p>So, this really is only the very beginning. The fact that we have two large, experienced nations with interplanetary ambitions, in the US and China, plus a relative newcomer — and further US-European and <a href="https://www.dw.com/en/japans-mars-moons-mission-leads-to-human-spaceflight/a-54961901" target="_blank">a Japanese Mars mission</a> waiting in the wings — there is a definite sense of <a href="https://www.dw.com/en/a-new-race-to-the-moon-us-wants-to-lead-the-way/a-48380594" target="_blank" rel="noopener noreferrer">a new race beyond what humans have done before in space</a>.</p><p><span></span>These three missions were timed to launch when the distance between the Earth and Mars was relatively short. It usually takes about nine months to get to Mars, but these missions were able to cut that trip down to seven. And despite the added challenges brought by the COVID-19 pandemic, not one of them missed the opportunity to go.</p><p><span></span><em>Reposted with permission from </em><em><a href="https://www.dw.com/en/three-mars-missions-arriving-in-february-2021/a-56472730" target="_blank">Deutsche Welle</a>.</em><a href="https://www.dw.com/en/three-mars-missions-arriving-in-february-2021/a-56472730" target="_blank"></a></p>

2021 begins as a year of Mars. Although our red planetary neighbor isn't as prominent as it was last autumn, it is still noticeable with its characteristic reddish color in the evening sky until the end of April. In early March, Mars shines close to the star cluster Pleiades in the constellation Taurus.
A Landing Like a James Bond Movie<img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTUyOTIwMS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY3MDU5MDQ2Nn0.aLE-s5r9YhoJs40XbavhUwUXdY97iykXqo0OO0S5eso/img.jpg?width=980" id="19fa1" class="rm-shortcode" data-rm-shortcode-id="c758d3cd0d3e11fbd5290bb95da86396" data-rm-shortcode-name="rebelmouse-image" data-width="700" data-height="394" />
NASA's Mars 2020 Perseverance rover (shown in artist's illustration) is the most sophisticated rover NASA has ever sent to Mars. Ingenuity, a technology experiment, will be the first aircraft to attempt controlled flight on another planet. Perseverance will arrive at Mars' Jezero Crater with Ingenuity attached to its belly. NASA<p>The highlight of this year's Mars exploration is the landing of the NASA rover "Perseverance" on February 18. Once the spacecraft enters the atmosphere it will be slowed down by friction. The heat shield will surpass 1,000 degrees Celsius. Later, parachutes will deploy to slow it down even more. Roughly two kilometers above the planet's surface, a sky crane comes into play. Four thrusters keep the crane properly oriented.</p><p><span></span>The rover is connected to the crane by nylon tethers. Upon approach of Mars' surface, the sky crane will lower Perseverance down about 7 meters. Once the rover has touched down, the tethers are cut and the sky crane flies off to land somewhere else on the surface.</p><p>Entry, descent and landing takes just seven minutes – the so-called seven minutes of terror. The flight team can't interact with the spacecraft on Mars. Experts have to sit and watch what's happening more than 200 million kilometers away. Radio signals from the spacecraft need about 11 minutes to travel in one direction. When the control center in Pasadena, California receives the message that entry has begun, Perseverance will already be on the ground. There is only one chance for a smooth landing. Any error could mean the mission is lost. The audacious sky crane maneuver would be a great feat in any action movie. But NASA knows how to do it – the Curiosity rover landed with a sky crane in 2012.</p>
Life on Mars?<p>Scientists want to use Perseverance to explore whether there is or ever has been life on Mars. Today the planet is a hostile environment – dry and cold with no magnetic field shielding the harsh radiation from space. Life as we know it can't survive on the Martian surface right now. But billions of years ago, Mars was hotter and wetter and had a shield against radiation. So it is at least plausible that simple microbes developed there. Maybe they live in the soil now, one or two meters below the surface. Perseverance will collect samples to find out. A future mission by NASA and the European Space Agency (ESA) will pick up the samples and return them to Earth. But this won't happen before 2030.</p>
The Long Wait for James Webb<img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTUyOTIxMS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY2OTM1MDUzNX0.0Jmw-vIz6zuOa7eNsVX2oVzc0L6AFp05cAs4QbzdK6c/img.jpg?width=980" id="9cf3e" class="rm-shortcode" data-rm-shortcode-id="d46a2f73a4a2e32a9775087750c92431" data-rm-shortcode-name="rebelmouse-image" data-width="700" data-height="394" />
The Hubble Space Telescope has been orbiting the Earth for more than 30 years. NASA<p>The Hubble Space Telescope's images of planets, nebulae, star clusters and galaxies are legendary. The cosmic eye, launched in 1990, is likely to fail towards the end of this decade. The James Webb Space Telescope will be its successor. It is scheduled to launch on October 31 with a European Ariane 5 rocket from the Kourou spaceport in French Guiana.</p><p><span></span>The launch date is about 14 years later than planned when the project began in 1997. At almost $10 billion (€8.2 billion), the telescope is more than ten times as expensive as originally conceived. Its namesake James Webb was the NASA administrator during the height of the Apollo project in the 1960s.</p><p>Astronomers expect completely new insights from James Webb Telescope images, such as how the universe came into being, how it developed and how galaxies, stars and planets are formed. The instrument will observe the earliest childhood of the cosmos and photograph objects that already existed in the universe 200 to 300 million years after the Big Bang. James Webb, as the experts call the telescope for short, may even provide information about possibly inhabited exoplanets – planets like ours orbiting stars other than the Sun. </p>
A Sensitive German Camera<img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTUyOTIxNS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxOTE0MzY3Mn0.o3aPaW5t0MFkEgeJl0HQ1V9lz6WDxKVGXyYWvpfoYyk/img.jpg?width=980" id="6ff49" class="rm-shortcode" data-rm-shortcode-id="187458ae2291c2aeb3bd36bc1ed777e0" data-rm-shortcode-name="rebelmouse-image" data-width="985" data-height="657" />
The fully assembled James Webb Space Telescope with its sunshield and unitized pallet structures that will fold up around the telescope for launch. NASA<p>The mirror of the James Webb Space Telescope is 6.5 meters in diameter and consists of 18 hexagonal segments. The entire instrument unfolds in 178 steps over a period of several months. Only then – probably in the spring of 2022 – will we see its first images.</p><p>Many communication or reconnaissance satellites only unfold in space. However, not every micrometer is as important as with this telescope. </p><p>NIRSpec, one of the four cameras on board, was built at Airbus in Ottobrunn near Munich. It is made of an unusual material: ceramic. Both the basic structure and the mirrors are made of this very light, hard and extremely temperature-insensitive material. With good reason – the large camera has to withstand a lot in space. It is cooled to around -250 degrees Celsius in order to register the weak infrared or thermal radiation from the depths of space. Plastic or metal bend and lead to blurred images. Ceramic, on the other hand, remains in perfect shape.</p><p>The NIRSpec instrument will examine, among other things, emerging stars and distant galaxies. The ceramic camera is incredibly sensitive – it could register the heat radiation from a burning cigarette on the Moon. Thanks to this precision, astronomers will get completely new insights into the cosmos with the James Webb Telescope and NIRSpec.</p>
No Flight to the Moon but to the ISS<p>It's not very likely that the Orion spacecraft from NASA and ESA will start its maiden voyage to the Moon before the end of 2021. As part of the Artemis-1 mission, it will remain in space for four weeks and will orbit the Moon for a few days. There will be no crew on board for the first flight, but two dummies from the German Aerospace Center, which use thousands of sensors to measure the conditions that human beings would be exposed to. The Orion capsule comes from NASA, while the ESA supplies the service module. The service module, which is being built by Airbus in Bremen, provides propulsion, navigation, altitude control and the supply of air, water and fuel. After problems with an engine test in mid-January, the new NASA large rocket Space Launch System (SLS), with which Orion is supposed to be launched, is unlikely to be operational until early 2022.</p><p><span></span>Matthias Maurer from Saarland is scheduled to fly to the International Space Station (ISS) in October. The flight will be in a Crew Dragon capsule from Cape Canaveral. Maurer will live and work in the orbital outpost for six months. He is currently training to work on numerous scientific experiments. Maurer will be the twelfth German in space.</p><p>So far, Germany has only sent men into space. In mid-March, ESA will start the next application process for astronauts. A few years ago, the private initiative Die Astronautin ("She is an astronaut") showed that there are numerous excellent female applicants.</p>
Two Lunar Eclipses<p>Even if there is no flight to the Moon, sky fans are looking forward to two eclipses this year. On May 26, there will be a lunar eclipse between 9:45 and 12:53 UTC. From 11:10 to 11:28 UTC, the Moon will be completely in the Earth's shadow. It can then only be seen in a copper-red light. This is sunlight that is directed into the Earth's shadow by the Earth's atmosphere – reddish, like the sky at sunset. This eclipse can be observed throughout the Pacific, and will be best viewed in Australia, New Zealand, Hawaii, and Antarctica. In Europe, the Moon will be below the horizon and therefore the eclipse will not be visible.</p><p>This also the case for the partial lunar eclipse on November 19. From 07:18 to 10:47 UTC, the Moon will be partly in the shadow of the Earth. In the middle of the eclipse (around 9:03 UTC) 98% of the Moon will be eclipsed. The spectacle will be best seen in North America, Greenland, East Asia and much of the Pacific, such as Hawaii and New Zealand.</p>
Two Solar Eclipses: One Annular, One Total<p><span>In 2021, the Moon will pass right in front of the sun, twice. On June 10, the moon will be nearly in the furthest point of its elliptical orbit around Earth. So it will be too small to cover the sun completely. In the middle of this eclipse, an annulus of the sun will remain visible. The sun's ring of fire appears between 9:55 and 11:28 UTC for a maximum of four minutes – but it will only be visible in the very sparsely populated areas of northeast Canada, northwestern Greenland, the North Pole and the far east of Siberia.</span></p><p>In the North Atlantic, Europe and large parts of Russia, an eclipse will be seen at least partially. Between 8:12 and 13:11 UTC, the Sun will appear like a cookie that has been bitten into as the Moon covers parts of the bright disk. In some places, the eclipse will last about two hours. In Central Europe, a maximum of one-fifth of the sun will be covered.</p>
Dark Sun Over Antarctica<p>The celestial event of the year will be a total solar eclipse on December 4. In a 400-kilometer-wide strip, the New Moon will cover the sun completely. For a maximum of one minute and 54 seconds, day will turn to night. For that short time, the brightest stars can be seen in the sky and the flaming solar corona can be seen around the dark disc of the Moon.</p><p><span></span>Unfortunately, hardly anyone will get to see this cosmic spectacle because the strip of totality only runs through the Southern Ocean and the Antarctic. From 7:03 to 8:04 UTC the umbra of the Moon moves across the Earth's surface – and perhaps some ships' crews will enjoy the solar corona.</p><p>Only during the few minutes of totality is it possible to look safely at the Sun with the naked eye. During the partial phase or in the case of an annular eclipse, suitable protective goggles are necessary to watch the spectacle. Normal sunglasses are not safe. Looking unprotected into the sun can lead to severe eye damage or even blindness.</p>
Two Giant Planets in Northern Summer and Southern Winter<p>Venus, our other neighboring planet, will be behind the sun on March 26. It is not visible for the first few months of the year. From the end of April through Christmas, it will be visible as an evening star in the sky after sunset. The planet, shrouded in dense clouds, is the brightest object in the sky after the Sun and the Moon. The best visibility will be from September to December.</p><p>The giant planet Jupiter is in its best position of the year on August 20. It then shines in the constellation Capricorn, only disappearing from the evening sky at the beginning of next year. The ringed planet Saturn is also in the constellation Capricorn and can be observed particularly well on August 2. </p><p>Jupiter and Saturn are the stars of summer in the Northern Hemisphere and those of the long winter nights in the Southern Hemisphere. They are in the same area of the sky, almost forming a double star with Jupiter being the brighter of the two.</p>
Shooting Stars in August and December<p>There are certain periods when the Earth crosses the orbital path of a comet and shooting stars are much more likely than on other nights. Many small stones and dust particles are scattered on comet orbits, which light up the Earth's atmosphere for a moment when they enter.</p><p>The Perseids are particularly promising: August 9-13, a few dozen meteors (the technical term for shooting stars) will scurry across the sky per hour. The traces of light will seem to come from the constellation Perseus, near the striking celestial W of Cassiopeia. The Geminids – meteors coming from the constellation Gemini – will be similarly exciting with up to 100 shooting stars per hour, December 10-15.</p>

2020 will be the year of Mars. The red planet will approach Earth in early October to within 62 million kilometers. Four space agencies are set to take advantage of this close encounter and send spacecraft to Mars. The European Space Agency (ESA) will launch its ExoMars rover on a Russian Proton rocket from the Baikonur cosmodrome. ExoMars is set to land on the surface, dig into the soil and look for traces of past life. They will be looking for possible living microbes about half a meter below the Martian surface. Above it, harmful cosmic radiation makes life as we know it impossible.

Elon Musk has a plan, and it's about as audacious as they come. Not content with living on our pale blue dot, Musk and his company SpaceX want to colonize Mars, fast. They say they'll send a duo of supply ships to the red planet within five years. By 2024, they're aiming to send the first humans. From there they have visions of building a space port, a city and, ultimately, a planet they'd like to "geoengineer" to be as welcoming as a second Earth.
If he succeeds, Musk could thoroughly transform our relationship with our solar system, inspiring a new generation of scientists and engineers along the way. But between here and success, Musk and SpaceX will need to traverse an unbelievably complex risk landscape.

Following global pressure on pet food companies, industry giants Mars and Nestlé have announced that they will take steps to ensure their pet food supply chains are free of human rights abuses and illegally caught seafood. Their commitments to act on transshipping at sea increase the need for global seafood giant Thai Union, a supplier for both companies, to eliminate any outstanding risks of human rights abuses and illegal, unreported and unregulated fishing in its own supply chains.
Nestlé has committed to a full ban on transshipment at sea in its supply chains, while Mars has committed to suspend the use of transshipped products in its supply chains if its seafood suppliers cannot adequately address the human rights and illegal fishing issues associated with the practice in the coming weeks.
"Pet owners and activists have demanded that companies eliminate human rights abuses from their pet food supply chains. This move toward stopping out of control transshipment at sea means we're finally seeing results," said Greenpeace USA oceans campaigner Graham Forbes.
"These are the two largest pet food companies in the world and their commitments to address transshipping at sea will put significant pressure on suppliers like Thai Union to show the leadership needed to clean up their own seafood supply chains. We'll be closely monitoring Mars' and Nestlé's progress to ensure these policies lead to real changes on the water," added Forbes.
Greenpeace launched a campaign in 2016, Cats vs. Bad Tuna, to demand that Mars ensure its supply chains were free of any potential human rights abuses. A Greenpeace Southeast Asia report, Turn the Tide, demonstrated the unacceptably high risk of tainted seafood entering numerous supply chains throughout 2016, including Nestlé and Thai Union's. Nestlé immediately committed to address the concerns when they were raised in the report. Mars committed to tackle unchecked transshipment at sea in its pet food supply chains this month.
"Over the past several years, Nestlé and Greenpeace have worked together to strengthen Nestlé's policies governing the procurement and responsible sourcing of seafood," said Nestlé Purina PetCare head of sustainability Jack Scott. "In light of Greenpeace's research findings, Nestlé has committed to a ban on all transshipments at sea."
Transshipment is a process through which companies move fish from one vessel to another, enabling them to remain at sea for extended periods of time to plunder the oceans, dodge regulations and keep fishers as a captive workforce. In addition to its connections to human rights abuse, transshipment at sea provides an opportunity for illegal fishing vessels to unload their illegally caught loads into supply chains, away from port authorities. In 2015, an estimated 40 percent of these transfers happened on the high seas, outside of the jurisdiction of national authorities. Transshipment at sea has also been linked to other organized crime, including drug, weapon and wildlife trafficking.
Mars' and Nestlé's commitments send a strong message to Thai Union to address transshipment in its supply chains. Greenpeace is currently pressuring Thai Union to make sweeping changes for workers and our oceans across its seafood supply chains. Greenpeace has campaigned on Thai Union since 2015 and is asking the company to lead the seafood industry by ending transshipment at sea, addressing overfishing and destructive fishing and increasing traceability from sea to plate.
"Mars recognizes the risks of transshipment at sea. We want to see human rights respected and the environment protected in our seafood supply chains" said Isabelle Aelvoet, global sustainability director at Mars Petcare.
"The current problems associated with transshipment are serious and demand urgent attention. We are committed to working with our suppliers to remedy these problems, but if we cannot resolve these issues to our satisfaction quickly, we will seek to end the use of transshipped products in our supply chains until these serious problems are fixed."
Thursday's news follows a new report from Global Fishing Watch highlighting the problems with transshipment at sea. The report found that from 2012-2016, refrigerated cargo vessels participated in more than 5,000 likely transshipments. Concerns were raised about Mars and Nestlé supply chains in a 2015 New York Times investigation into human rights abuses at sea.
It's no secret that Elon Musk wants to take humans to Mars by 2025, but now, for the first time, he will explain how he plans to do it.
