NASA certifies SpaceX for regular manned flights into space

NASA has certified the space capsule Crew Dragon from SpaqceX for regular manned flights into space, as the first privately manufactured spacecraft ever. The last time such a certification was granted was 40 years ago , at that time for the space shuttle, the US space agency now explains.

For Elon Musk and the company, the step is an important one Milestone. NASA is no longer dependent on ordering flights to the ISS for its astronauts in Russian space capsules and SpaceX is thus temporarily the only commercial NASA contract partner for manned flights into space.

No longer dependent on Russia With the certification, NASA can now implement its Commercial Crew Program after years of preparation. 2014 had commissioned the space agency SpaceX and Boeing to develop and test space capsules for manned flights in Earth orbit. This was preceded by the end of the space shuttle program, which is why the USA had no more opportunity since 2011 to fly astronauts into space themselves. Actually, the space capsules developed by the two companies should already 2017 be ready, but that had been delayed again and again. Rocket launch with heise online (First Kerbal, then SpaceX)

In May the first take-off was successful and the first regular flight with SpaceX technology is imminent. The bookings in Russia cost NASA around 71 million US dollars per Seat, at SpaceX it should be around 55 million dollars, writes CNBC.

At SpaceX, certification for regular flights is now seen as the culmination of years of development, testing and training. The engines have been tested over 700 times, the docking system over 500 Times. Eight million hours had flowed into HiL tests (Hardware in the Loop) and the parachutes were almost 100 Tried times. Manned flights into space are the core mission of SpaceX and it is honored to be able to help NASA usher in a new era of exploration of space. “I am very proud that we are returning to regular manned space launches from American soil with American rockets and spacecraft,” added NASA chief Jim Bridenstine.

First regular flight is pending The first regular flight of a SpaceX capsule to the ISS (Crew-1) is scheduled to start on Saturday and NASA astronauts Michael Hopkins, Victor Glover and Shannon Walker and her Japanese colleague Soichi Noguchi. They should then stay on the International Space Station for six months. Thanks to the space capsule from SpaceX, NASA can now increase the number of its astronauts on the ISS from three to four, which means that seven space travelers can now inhabit the outpost of humanity at the same time. In December, Boeing plans to start another unmanned test flight to the ISS so that it can also fly astronauts there next year.

Independent testing: NASA and ESA can bring soil samples from Mars to Earth

NASA and ESA are now able to bring soil samples from Mars to Earth in order to have them examined more closely. That is the conclusion of an independent commission of inquiry on the “Mars Sample Return” mission, which, among other things, recommends continuing the preparation.

At the same time, the auditors have made a lot of suggestions to address potential problems preventively. The US space agency feels just as confirmed by the report as it is with its European counterpart. ESA is a partner of the ambitious mission and welcomes the result of the review.

A complicated, multi-stage undertaking The Mars Sample Return mission is based on several spacecraft, NASA explains once more. With the Mars rover Perseverance, the first of these is already on the way to the Red Planet. After the beginning of his landing 2021 he is supposed to take soil and rock samples with a drill and pack them up in small containers the surface. With two more rocket launches 2026 their transport should be initiated. For this purpose, ESA will deliver the “Sample Fetch Rover”, which collects the samples and uses them to equip NASA’s “Mars Ascent Vehicle”. It should then be the first spacecraft to leave Mars and bring the samples to ESA’s “Earth Return Orbiter”, which will wait in orbit and bring the samples to Earth.

The review of the extremely ambitious project that has now been presented took place earlier in the course of development than in any such mission before, explains NASA. Normally such checks would not be carried out until much later. Among other things, one wants to guarantee a success of the mission, which is one of the most important of the US space agency and should not only help to answer important questions about the history of Mars, but also to prepare manned missions to the red planet. The main recommendations of the report now mainly concern differences in management and organization between NASA and ESA, which must not cause problems.

“Great news” The result is great news for the campaign, says David Parker, ESA Director for Robotic and Astronautical Exploration: “It reinforces our shared vision of bringing scientists to pristine pieces of the Red Planet That they can study with laboratory equipment and techniques that we could never take to Mars. ” NASA chief Jim Bridenstine says the mission must be carried out by his space agency as a leading member of the global community. You know about the challenges and therefore look particularly closely at this architecture: “And that is the reason why we ultimately achieve great things.”

K2-141b: An exoplanet with a surface, ocean and atmosphere made of rocks

Researchers have found an exoplanet with a particularly extreme composition: the surface, the ocean and an atmosphere on K2 – 141 b are all exposed Rock together. They have simulated details of the extreme conditions on the exoplanet on the basis of known data, for example about density, with the help of computer models, explain the researchers at McGill University in Canada. Accordingly, there winds whipping at more than 5000 kilometers per hour over a 100 kilometers deep lava ocean . What is the water cycle on earth is analogous to the exoplanet, only with the basic substances sodium, silicon monoxide and silicon dioxide.

Like the terrestrial water cycle, only different K2 – 141 b was discovered with the NASA Kepler space telescope and orbits its star, which is more than 200 light-years away from us, in just 0, 00716 AE (Astronomical Unit) distance. That is less than one percent of the distance of the earth from the sun and more than 40 times closer than Mercury to the sun. Because K2 – 141 b is so close to its star, it rotates bound. On the side that is always facing the star, temperatures of approximately 3000 degrees Celsius prevail, on the opposite side less than – 200 Centigrade. According to the researchers, who present their work in the Monthly Notices of the Royal Astronomical Society, their predictions about the conditions should be confirmed with NASA’s James Webb Telescope.

The temperatures are so high that the rock that makes up the exoplanet not only melts, but evaporates, creating the thin atmosphere that could be observed with telescopes. The gaseous rock is therefore blown by the extreme winds to the night side, where it condenses and from there flows back into the ocean. Unlike on Earth, however, this cycle cannot last forever because the composition of the rock changes over time. The surface and the atmosphere of K2 – 141 b change slowly. With fresh data from NASA’s Spitzer space telescope, they now want to check their predictions, and the James Webb telescope could then determine whether the atmosphere actually behaves like this.

NASA: Voyager 2 successfully radioed again after months of radio silence

NASA, which is almost 19 billions of kilometers from Earth -Sonde Voyager 2 received signals from Earth, carried out commands and returned an acknowledgment for the first time in months. This has now been announced by the US space agency, which is currently repairing the only antenna in its deep space networks that can still communicate with the probe. With the exception of its sister probe, it is further away from us than any other human object. The repairs to the antenna should be completed in February and will enable future communication not only with the 1977 started probe.

Voyager 2 was before 43 Years started, a few days before Voyager 1 and thus only 20 Years after the first artificial satellite ever: Sputnik. Both made use of favorable constellations of the planets in the outer solar system on their routes and passed Jupiter and Saturn. Voyager 1 then turned north, Voyager 2 visited Uranus and Neptune before heading south. After decades they have passed the limit of the heliosphere and are on their way to the stars. They will survive us on earth, because the probability that they will stumble upon anything on their lonely path is almost zero.

The maintains for communication with their interplanetary probes NASA has three radio antennas 43 meters in diameter in California, Spain and Australia. The locations are chosen so that each probe should be able to contact at least one antenna at any time, regardless of its position in the solar system. Only these antennas are powerful enough to reach the Voyager probes, signals there require more than 13 (Voyager 2) or 21 hours (Voyager 1). Voyager 2 is now so far south of the orbital plane of the planets that it can no longer see the locations in the northern hemisphere of the earth and can only be radioed from Canberra, explains NASA.

Virgin Galactic: VMS Eve and SpaceShipTwo tests continue

Virgin Galactic announced second flight for the VMS Eve aircraft and the upcoming SpaceShipTwo tests which, in addition to improving the spaceplane project, will also bring some experiments provided by NASA.

When it comes to Space and private companies, the first thought certainly goes to SpaceX. But this is not the only one who looks to the sky for the possibility of earning. There is also Virgin Galactic which however has a different strategy from that of Elon Musk as regards technologies

VMS Eve took off for the second time

One of the latest news concerns VMS Eve , the great plane that Virgin Galactic will use SpaceShipTwo for the launch of the spacecraft. This involves adopting a different solution than that of a rocket as a launcher. Given its particular structure, the tests of VMS Eve are followed with particular interest also given its wingspan of 43 meters.

VMS Eve takes to the skies for its second flight of the day as we continue preparations for our first spaceflight from New Mexico which is due to take place this Fall. Pilots for this flight are Kelly Latimer and Mark Stucky. They are joined by Flight Test Engineer, Colin Bennett pic.twitter.com/1A0054 jUqd

Dave Mackay (chief pilot) stated “VMS Eve has the ability to test pilot competence by simulating the planing and approach phase for SpaceShipTwo pilots. The cockpit structure of Eve is almost identical to that of Unity: same pilot seats and windows, as well as controls and instruments This, coupled with the fact that with Eve’s landing gear down and a set of aerodynamic brakes, descends at the same angle of trajectory as the SpaceShipTwo, means that the crew can practice with the same approach and pattern of landing when they fly to Unity – with most of the same information and the same view outside d at the window. This makes Eve a very valuable flight simulator for the final approach and landing phases of the spacecraft “.

SpaceShipTwo flight tests continue

The company has released a video showing the plane taking off from Spaceport America, the spaceport of New Mexico (in the United States United States). Mike Moses (President of Space Missions and Security) said testing is continuing as planned, thanks to pilot CJ Sturckow. In particular, the focus is on meeting all safety objectives in order to finally be able to welcome tourists who want to travel with Virgin Galactic .

Moses added “CJ will be alongside our chief pilot, Dave Mackay, in the cockpit Today, as we are testing a number of key points to take us to the next stage of our flight test program. While we are planning for CJ and Dave to reach Space, if the test conditions of the day suggest a shorter flight, it will be fine anyway and we will be back to flying soon. The space flight system is designed for a quick commercial turnaround, so it’s much better to stay on the side of caution and go back to base to understand the data and prepare for another test flight “.

In the tests of SpaceShipTwo this time there will also be three payloads provided by NASA . This will change the flight path of the spacecraft which will not stop in the inverted pitch position to show the Earth as the aircraft is tilted by 270 °. Choosing to host payloads will serve to generate revenue for Virgin Galactic as well as helping scientific research.
