Can Dragon spacecraft fly people to the Moon? It is a complex puzzle

After a couple of minutes, Endeavour lose almost all of its own orbital velocity. Sinking into the lower air, its parachutes deployed in a careful arrangement, along with the spacecraft drifted down from blue sky into blue seas. They had been home. For the very first time in 4.5 decades, astronauts returned from distance and splashed down to the sea, such as the Apollo-era heroes that walked round the Moon. This really is a Herculean job for the bureau's administrator, Jim Bridenstine, who's balancing politics, financing, and technical challenges to drive NASA and its contractors ahead. Right after the landing, Bridenstine revived his pitch to get this particular Artemis Moon program through a splashdown news conference. Wearing a polo shirt emblazoned with the Artemis emblem, he explained,"We need to be certain that another generation does not overlook this chance. Today was a fantastic success, but it was only a start. Afterward, Bridenstine added this remark:"When

Greenland's ice sheet could have struck a tipping point that puts it in a lasting path to fully evaporating.

Snowfall that generally replenishes Greenland's glaciers annually can't keep up with the speed of ice melt, according to investigators at Ohio State University. That usually means that the Greenland ice sheet - the planet's second-hand ice hockey body - will continue to get rid of ice if global temperatures ceased climbing. In their study, published Thursday in the journal Nature, the scientists examined 40 decades of monthly satellite information from over 200 big glaciers which are draining to the sea across Greenland. Total melting of the Greenland ice sheet can increase sea levels 23 ft (~7 metres) from the year 3000. If this occurs, the sea would consume coastal towns throughout the world. Greenland's ice hockey is currently the world's biggest single contributor to sea-level rise. "Even though the weather were to remain the exact same or perhaps get a bit colder, the ice sheet could still be losing mass" However, this is simply one of several climate

Ariane 5 rocket delivered a robotic space tug along with a set of industrial communications satellites to orbit

An Ariane 5 rocket delivered a robotic space tug along with a set of industrial communications satellites to orbit Saturday after a fiery blastoff from French Guiana, debuting new updates in Arianespace's first mission because briefly suspending launching operations earlier this season on account of this coronavirus pandemic. Over an hour after, the rocket deployed three commercial satellites. The Ariane 5's third launching of 2020 was scheduled for July 31, but a detector issue to the rocket's center stage hydrogen tank compelled Arianespace officials to abort the countdown about two minutes prior to liftoff. Ground crews in the Guiana Space Center gathered back the rocket to its construction and replaced the detector a week, then returned the Ariane 5 into the launching pad Thursday. The launch team postponed the Ariane 5 takeoff 31 minutes Saturday to wait to get greater upper level wind conditions. After the winds enhanced, the countdown resumed along with the Ariane 5

Trump breaks with CDC manager on the potential to get 'worst autumn' amid pandemic, flu season

President Trump on Saturday said he disagreed with an examination from the mind of the Centers for Disease Control and Prevention (CDC) the United States could face the "worst drop" from a public health standpoint if Americans don't follow instructions to calm the spread of this novel coronavirus. "You can not compare it to 1917. This was unbelievable," Trump continued, speaking to the Spanish influenza, which infected an estimated 500 million people globally and is thought to have killed at least 50 million. At Saturday evening, the coronavirus had infected over 21 million internationally because it appeared in China late last year and had murdered over 768,000 globally, according to Johns Hopkins University. The U.S. accounts for its most cases worldwide, with over 5.3 million. Redfield in a meeting Wednesday with WebMD reported that when people don't follow public health advice, the U.S. may confront "the worst autumn, by a public health standpoint,
