Mark Thomas (CEO - Reaction Engines) and Adam Dissel (President - Reaction Engines Inc.) talk about the achievement of reaching Mach 5 Tue, 2019-10-22 07:14 Reaction Engines has successfully tested its innovative precoolerat airflow temperature conditions representing Mach 5, or five times the speed of sound, marking a significant milestone in the development of its SABRE™ engine and paving the way for a revolution in hypersonic flight and space access. The precooler heat exchanger is a vital component of Reaction Engines’ revolutionary SABRE air-breathing rocket engine and is an enabling technology for other precooled propulsion systems and a range of commercial applications. This ground-based test achieved the highest temperature objective of the Company’s HTX testing programme and took place at its specially constructed unique facility at the Colorado Air and Space Port, United States. During the latest series of tests, Reaction Engines’ unique precooler successfully quenched airflow temperatures in excess of 1,000°C (~1,800°F) in less than 1/20th of a second. The tests demonstrated the precooler’s ability to successfully cool airflow at speeds significantly in excess of the operational limit of any jet-engine powered aircraft in history. Mach 5 is more than twice as fast as the cruising speed of Concorde and over 50% faster than the SR-71 Blackbird aircraft – the world’s fastest jet-engine powered aircraft. This most recent test builds upon the success of previous HTX hot tests undertaken in April which saw the precooler successfully operate at temperatures of 420ᵒC (~788ᵒF) – matching the thermal conditions corresponding to Mach 3.3 flight. Commenting, Mark Thomas, Chief Executive, Reaction Engines, said: “This is a major moment in the development of a breakthrough aerospace technology which has seen Reaction Engines’ precooler tested at Mach 5 airflow temperature conditions, smashing through previous achievements at Mach 3.3 temperatures and paving the way for hypersonic flight. In addition to its use in our SABRE class of air breathing rocket engines, there are numerous exciting commercial applications for our precooler technology, which delivers world-leading heat transfer capabilities at low weight and compact size, and we are seeing significant interest from a range of potential customers and technology partners.” Reaction Engines’ patented precooler heat exchanger has the potential to be used in a wide range of commercial thermal management applications. These include the development of precooled systems that would significantly enhance the performance of existing jet engine technology, along with applications in automotive, aerospace, energy and industrial processes. The major testing milestone is the culmination of 30 years of engineering innovation since Reaction Engines was founded in 1989 by three propulsion engineers from Rolls-Royce, Alan Bond, Richard Varvill and John Scott-Scott. Richard Varvill, Reaction Engines’ co-founder and current Chief Technology Officer, said: “This is a momentous landmark for Reaction Engines in the development of its SABRE engine, which has the potential to revolutionise both access to space and high-speed flight by powering aircraft to five times the speed of sound. The performance of our proprietary precooler technology was validated at hypersonic flight conditions and takes us closer to realising our objective of developing the first air-breathing engine capable of accelerating from zero to Mach 5.” The HTX hot heat exchanger testing programme is a significant milestone on the roadmap to enabling transformational SABRE powered space access systems and has been keenly supported by the UK Space Agency (UKSA) and European Space Agency (ESA). In March, the two agencies reviewed and validated the preliminary design of the demonstrator engine core of SABRE, which Reaction Engines will use to undertake ground-based testing at its under-construction TF1 test facility at Westcott, Buckinghamshire, UK. The HTX hot heat exchanger test programme was supported under a contract to the Company’s US subsidiary Reaction Engines Inc. by the Defense Advanced Research Projects Agency (DARPA). The precooler test item was designed and constructed at Reaction Engines’ headquarters in the UK, before being shipped to the Company’s Colorado site for testing. Following this significant testing milestone, the Company will embark on achieving the next steps of the SABRE programme while also pursuing nearer-term opportunities that will benefit from the addition of the Company’s heat exchanger technology. Over the last four years Reaction Engines has raised over £100m from public and private sources and has secured investment from BAE Systems, Rolls-Royce and Boeing HorizonX. https://www.reactionengines.co.uk/news/reaction-engines-test-programme-fully-validates-precooler-hypersonic-heat-conditions

Original Air Date: Oct. 17, 2019 All the material we can see is just a small fraction of the universe. The rest, a full 95 percent, is invisible and mysterious. These are the enigmatic dark matter and dark energy. While dark matter keeps things like galaxies together, dark energy acts in an opposite way – it pushes groups of galaxies apart and expands the universe itself. This event will discuss how astronomers are working to map the universe’s dark matter so they can see the effects of dark energy. The results could help us understand if the universe will expand at an accelerating rate forever.

Originally slated for a two-year mission, the second of the twin Van Allen Probes spacecraft will be retired just prior to running out of propellant, more than seven years after launch. On October 18, 2019, at about 12:30 p.m. EDT, spacecraft A of the Van Allen Probes mission will be shut down by operators at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. The command — the 4,781st sent to spacecraft A — is of the same type sent four months previously that terminated operations for spacecraft B, the second spacecraft of the mission. In February, the spacecraft were placed in a lower orbit that will eventually decay, letting the twin Van Allen Probes reenter and burn up in Earth’s atmosphere. These two spacecraft — designed, built and operated for NASA by Johns Hopkins APL — flew through the rings of charged particles trapped by Earth’s magnetic field known as the Van Allen belts to understand how particles were gained and lost by the belts. The spacecraft made major discoveries that revolutionized how we understand our near-Earth environment. More: https://www.jhuapl.edu/PressRelease/191017

The European Data Relay Satellite System (EDRS) is the first commercial application of optical satellite communications in space. If this data highway in space is completely extended, the system will contain four optical communication satellites in 36,000 kilometers above our Earth. So called Laser Communication Terminals (LCT) are the centerpiece of EDRS. LCT links Low Earth Orbit satellites to their geostationary relay partners and enables fast and secure transfer of large quantities of data in near real-time transmission to end users. Avoiding each traffic jam, LCT send important information like satellite images, weather or climate data directly on the fast lane. This kind of technology was financed by the DLR Space Administration with funds from the German Federal Ministry for Economic Affairs and Energy and developed by German industry. https://www.dlr.de/rd/en/desktopdefault.aspx/tabid-4161/3338_read-56894/ Animation by by the DLR Space Administration Deutsche Version: https://youtu.be/H53k0Y5slyM

Check out Charles Liu’s book: https://amzn.to/2VOM8v6 On this episode of StarTalk Radio, we celebrate World Space Week! The annual event has been celebrating the “contributions of space science and technology to the betterment of the human condition” since its ratification by the United Nations in 1999. This year is no different except for the fact that our own Neil deGrasse Tyson, comic co-host Matt Kirshen, and astrophysicist and StarTalk geek-in-chief Charles Liu, PhD, are joining the celebration by answering your fan-submitted Cosmic Queries on a variety of cosmic topics! Explore the possibilities of higher dimensions in our universe. We investigate certain theories that allow for “compactified dimensions.” We also discuss Edwin Abbott’s iconic book, Flatland, and ponder how to explain a third dimension to someone in a two-dimensional universe. Next, we raise our sights to asteroids. What are the most common metals found on asteroids and how do mine them? Neil explains why, even if there is an abundance of curiosity, money is still always the driving factor. You’ll hear about the state of solar energy. Find out the real costs inherent in the solar marketplace. Charles sheds light (pun intended) on the difficulties of switching from old technology to new technology. We harken back to the rapid switch from horses to cars and debate why the switch from fossil fuels to renewable resources has taken so much longer. Discover more about speed of light travel: how you would protect those traveling in a vehicle at the speed of light, how The Flash is able to travel at the speed of light, and why it’s possible that you might not even be you at the speed of light. You’ll also hear about terraforming Mars and why the lack of atmosphere presents a big problem. Learn why it’s beneficial to put space telescopes on the far side of the Moon. Our trio weighs in on who will lead humanity’s journey through space? Governments, the private sector, or a combination of both? All that, plus, we discuss how to market space travel to those who find it unnecessary or extravagant. This episode originally aired on October 4, 2019. #StarTalk #NeildeGrasseTyson #Mars

This Solar Storm Forecast is sponsored in part by 3ric Johanson: http://instagram.com/scubist Although space weather continues to be quiet this week, the Sun has us in a clutch of suspense as we watch two coronal holes rotate ever closer to the Earth-strike zone. The first of these will send us a short burst of fast solar wind near week's end, while the other, larger coronal hole will send us a much larger burst of fast wind in about 10-12 days. This larger coronal hole has already brought us to storm levels the last two times it rotated Earthside and the hopes are it will give us yet another repeat performance. Aurora photographers should get ready for several shows, with the larger one bringing views of aurora to mid-latitudes near the end of the month. Outside of this, the Sun remains spotless, which means amateur radio operators and emergency responders are still suffering poor radio propagation on earth's dayside. However, GPS users should enjoy decent reception this week, even at low latitudes. Learn more details about the coming solar storms, catch up on aurora photographs from the last time these coronal holes were in view, and see what else our Sun has in store.

The very first exoplanet - a planet outside of our Solar System orbiting another star - was discovered in 1995 by Queloz and Mayor. They were awarded the 2019 Nobel Prize for Physics for this discovery. But why did they have to wait 24 years to win it? Often, it’s not just the discovery itself that’s worthy of the prize, but the legacy that discovery leaves. In this case, producing a whole new field of research in astrophysics and making 18,852 other research papers possible. #NobelPrize2019 Help discover more exoplanets by classifying transits in new data from the TESS telescope: https://planethunters.org ----- 16th century - 00:44 18th century - 01:49 19th century - 02:39 1950s - 03:29 1960s - 07:46 1970s - 08:56 1980s - 09:28 1990s - 10:08 2000s - 15:22 2010s - 20:34 ------ My new book 'Space: The 10 Things You Should Know' is out now worldwide!

The private sector may need the Outer Space Treaty to be updated before it can make any claims to celestial bodies or their resources. - The Outer Space Treaty, which was signed in 1967, is the basis of international space law. Its regulations set out what nations can and cannot do, in terms of colonization and enterprise in space. - One major stipulation of the treaty is that no nation can individually claim or colonize any part of the universe—when the US planted a flag on the Moon in 1969, it took great pains to ensure the world it was symbolic, not an act of claiming territory. - Essentially to do anything in space, as a private enterprise, you have to be able to make money. When it comes to asteroid mining, for instance, it would be "astronomically" expensive to set up such an industry. The only way to get around this would be if the resources being extracted were so rare you could sell them for a fortune on Earth.

Even as the first rockets were launched into space decades ago, aerospace knew it was a wasteful process. Rocket stages, motors, and complex equipment crashed into the ocean or burned up in the Earth’s atmosphere. Could spaceplanes bring the costs down? Flying to orbit with a combination of jet engines and rockets and then safely re-enter the Earth’s atmosphere again. Single-stage to orbit spacecraft and spaceplanes have always seemed out of reach, and actually not that practical. But what about a two-stage, fully reusable spaceplane? Exodus Space Corporation has been secretly working on this concept for a decade now, and what they’re proposing is pretty revolutionary.

In Washington Tuesday, Oct. 15 NASA provide an up-close look at the next generation spacesuits the first woman and next man to explore the Moon will wear as part of the agency’s Artemis program. NASA is preparing to send astronauts to the Moon by 2024 and is moving forward with design and development of the suits astronauts will wear on the lunar surface and other destinations, including Mars. The public event will take place at 2 p.m. EDT and feature NASA Administrator Jim Bridenstine, who will host a demonstration with spacesuit engineers. The spacesuit demonstration will air live on NASA Television and the agency’s website. Using ground prototypes, NASA will showcase its two spacesuits designed for lunar exploration – one for launch and re-entry aboard the agency’s Orion spacecraft, known as the Orion Crew Survival System, and one for exploring the surface of the Moon’s South Pole, known as the Exploration Extravehicular Mobility Unit (xEMU). The xEMU suit improves on the suits previously worn during the Apollo era and those currently worn during spacewalks outside the International Space Station. This new spacesuit will accommodate a broad range of astronaut sizes and features an improved fit, comfort, and mobility for the lunar surface. NASA recently sought input from industry on interest in future production of the xEMU spacesuit.

Size epitomises the universe... but as numbers climb, the question is what is the largest thing we have ever found? Well, the current largest-known cosmic structure, by definition, is the so-called Hercules-Corona Borealis Great Wall. This suspected galaxy filament was discovered through its apparent high frequency of Gamma Ray Bursts, and currently is the only structure in the universe known to exceed 10 billion light years. But the nature of the wall is still shrouded in mystery. Everything from its name, to its size, to its formation is debated by scientists... but with similar discoveries of massive GRB formations, our knowledge of distribution, matter and creation within the bounds of this universe is being pushed to the limit.

What exactly is it? What are the loops? And can it really defeat string theory in our quest for a Theory of Everything? Hosted by Matt O'Dowd Written by Graeme Gossel & Matt O'Dowd Graphics by Leonardo Scholzer Directed by: Andrew Kornhaber Executive Producers: Eric Brown & Andrew Kornhaber The holy grail of physics is to connect our understanding of the tiny scales of atoms and subatomic particles with that of the vast scales of planets, galaxies, and the entire universe. To connect quantum physics with Einstein’s general theory of relativity. Our search for a theory of quantum gravity is a century old, and we’ve talked quite a bit about it already, including what’s probably the lead contender - string theory. But string theory isn’t the only game in town - or so some physicists believe. There may be another way to reconcile the physics of the tiny and the gigantic - another way to a theory of quantum gravity that avoids a lot of conceptual baggage like tiny wiggling strings made of coiled up extra dimensions. That other way would be loop quantum gravity, and today we’re going to learn exactly what it is.

Exploration Ground Systems continued to make sure the mobile launcher is ready for Artemis I with a multi-arm swing test on Friday, October 4, 2019 at Launch Pad 39B at Kennedy Space Center in Florida. The Umbilical Arm Simultaneous Retract Test included retraction of the connections that will provide fuel, coolant and communications to the Space Launch System rocket up until launch. The umbilicals tested included the Interim Cryogenic Propulsion Stage Umbilical (ICPSU), the Core Stage Forward Skirt Umbilical (CSFSU) and the Core Stage Intertank Umbilical (CSIU).

What's the difference between an astronomer and an astrophysicist? - NASA's Michelle Thaller explains that these terms are used interchangeably: both are physicists who study objects and phenomena in the sky. - How can you become an astronomer? There is a defined path to take: Do an undergrad degree in astrophysics, physics, mathematics or computer science, then complete a doctorate in astrophysics. You could also work with astronomers by studying engineering and building telescopes. - In this fascinating explanation of what an astronomer's day-to-day job actually looks like, Thaller shines a light on the unexpected skills you might need and answers the question on every ambitious astronomer-to-be's mind: How will I know what to discover?

Wind-blown deposits known as transverse aeolian ridges (TARs) are frequently visible in images of the Martian tropics. They are bright ripples with heights of 2.6 meters and spacing that averages 47 meters. The TARs generally appear inactive and eroded, sometimes cratered or littered with boulders from nearby impacts and avalanches. (Narration: www.tregibbs.com.

ExoMars 2020 has passed a number of milestones. The European carrier module was delivered in March. The European rover, which contains nine instruments, has been assembled by Airbus UK and is under environmental testing in Toulouse. It should be integrated with the spacecraft by the end of the year. The spacecraft is now in the Thales Alenia Space test facilities in Cannes to start the environmental and performance verification test campaign that will last until February 2020. However, there remain some important challenges ahead for the parachute system of the descent module. Recent balloon high-altitude drop tests were unsuccessful. As a result, the next and final two drop tests, scheduled between January and March 2020, must be fully successful otherwise the mission cannot launch in 2020. The joint ESA and Russian mission consists of four elements: a carrier module to propel the spacecraft to Mars, a descent module, a surface science platform and the Rosalind Franklin rover, which will use its drill up to depths of two meters to search for signs of life.

This video of one month of solar activity was created using images from NASA SDO - almost 3000 separate photos were used. A few facts about the Sun FACTS ABOUT THE SUN The Sun accounts for 99.86% of the mass in the solar system. It has a mass of around 330,000 times that of Earth. It is three-quarters hydrogen and most of its remaining mass is helium. Over one million Earth’s could fit inside the Sun. If you were to fill a hollow Sun with spherical Earths, somewhere around 960,000 would fit inside. However, if you squashed those Earths to ensure there was no wasted space then you could fit 1,300,000 Earths inside the Sun. The surface area of the Sun is 11,990 times that of Earth. One day the Sun will consume the Earth. The Sun will continue to burn for about 130 million years after it burns through all of its hydrogen, instead burning helium. During this time it will expand to such a size that it will engulf Mercury, Venus, and Earth. When it reaches this point, it will have become a red giant star. The energy created by the Sun’s core is nuclear fusion. This huge amount of energy is produced when four hydrogen nuclei are combined into one helium nucleus. The Sun is almost a perfect sphere. Considering the sheer size of the Sun, there is only a 10 km difference in its polar and equatorial diameters – this makes it the closest thing to a perfect sphere observed in nature. The Sun is travelling at 220 km per second. It is around 24,000-26,000 light-years from the galactic centre and it takes the Sun approximately 225-250 million years to complete one orbit of the centre of the Milky Way. The Sun will eventually be about the size of Earth. Once the Sun has completed its red giant phase, it will collapse. It’s huge mass will be retained, but it will have a volume similar to that of Earth. When that happens, it will be known as a white dwarf. It takes eight minutes for light reach Earth from the Sun. The average distance from the Sun to the Earth is about 150 million km. Light travels at 300,000 km per second so dividing one by the other gives you 500 seconds – eight minutes and twenty seconds. This energy can reach Earth in mere minutes, but it takes millions of years to travel from the Sun’s core to its surface. The Sun is halfway through its life. At 4.5 billion years old, the Sun has burned off around half of its hydrogen stores and has enough left to continue burning hydrogen for another 5 billion years. Currently the Sun is a yellow dwarf star. The distance between Earth and Sun changes. This is because the Earth travels on a elliptical orbit path around the Sun. The distance between the two ranges from 147 to 152 million km. This distance between them is one Astronomical Unit (AU). The Sun rotates in the opposite direction to Earth with the Sun rotating from west to east instead of east to west like Earth.
