Boeing Starliner Wings Clipped. Will Launch Again Without a Crew.

Posted by in categories: complex systems, innovation, space, space travel

Boeing flubbed the first mission of the CST-100. Seemingly a routine mission for SpaceX after completing over 20 deliveries to the International Space Station, Boeing showed how not to do it. During the December 2019 Demo flight for the Boeing Starliner CST-100, the Starliner did not reach its planned orbit. Nor did the Starliner dock to the International Space Station as planned. Boeing was able to complete a number of mission objectives during the flight to comply with the milestones related to NASA’s Commercial Crew.

CST-100 Starliner OFT Recovery – December 22, 2019

On the ULA Atlas V rocket at 6:36 a.m. Friday, Dec. 20, the Boeing Starliner launched from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. Boeing has a long rich history in both aviation and spaceflight. This mission, already three years behind in schedule, should have been a slam dunk.

After launching to the incorrect orbit, Boeing was able to successfully recover the Starliner. NASA shared that Boeing’s CST-100 Starliner spacecraft did successfully complete the first land touchdown of a human-rated capsule at the White Sands Space Harbor in New Mexico at 7:58 a.m. EST (5:58 a.m. MST) on December 22, 2019. The landing followed a deorbit burn for the botched flight, separation of the spacecraft’s service module, and successful deployment of its three main parachutes and six airbags. Boeing’s approach to the Starliner is unique as the prior US-made capsules, including the SpaceX Dragon, are water recoveries.

Starliner settling softly to the ground on Airbags wasn’t enough.

The NASA and Boeing investigation into the spaceflight was disclosed in Early March 2020. The recommendations included a list of corrections that needed to be addressed prior to the Starliner launching again. The investigation documented 61 “corrective actions” for the company’s Starliner spacecraft. This type of test did do what it was supposed to do. Find issues before people are exposed to potentially dangerous situations. This human risk reduction is a hallmark of the NASA Commercial Crew Program which was put in place to alternatives to the Space Shuttle and Soyuz spacecraft. NASA associate administrator Doug Loverro shared with reporters on a conference call that he expected it months for Boeing to work through the list to be ready for another test flight.

Small Satellites are Expanding

Posted by in categories: satellites, space

Satellites come in all sizes and shapes. A small satellite or SmallSat is commonly considered to be a satellite that weighs less than 500 kg.

As a basic application of various satellite sizes by mass, the common distinction:

Short Summary of Satellite sizes

CubeSats are smaller yet.

CubeSats need to conform to specific criteria including shape, size, and mass. At this point, most people have become aware or are at least heard of CubeSats. (Cube Satellites). CubeSats (cube satellite, cube satellite) are a type of nanosatellites defined by the CubeSat Design Specification (CSD) or otherwise commonly known by the unofficial term “CubeSat standard”. Cubesats are small, and start off at the 1U size of 10xm x 10 cm x 11.35 cm ( yes not exactly a cube, but very close) Here are some standard CubeSat dimensions:

Notes from an Apocalypse

Posted by in categories: Elon Musk, space, transhumanism

O’Connell’s previous book, To Be a Machine, was an inspired journalistic exploration of “transhumanism”, the subculture that wants to fast-forward to a technological future in which man becomes part-machine. This one is haunted by the idea that, unless we change our ways, or even if we change our ways, our species does not have much of a future at all. For O’Connell, those fears had been sharpened by recent fatherhood.


A timely study of the world’s growing sense of doom ranges from tourists in Chernobyl to Elon Musk’s plan to colonise Mars.

Attacking Global Warming With Satellites

Artist impression of a Methane hunting satellite by Bluefield

Global warming is a complex problem that is not easy to solve. While world leaders seem to be dragging their feet over the issue, Yotam Ariel, founder of Bluefield, believes he might have at least one piece of the puzzle sorted. Methane monitoring from space. By leveraging a network of microsatellites with a proprietary sensor, Bluefield plans to deliver alerts and analytics to oil and gas clients to help combat the inadvertent release of methane gas

Methane, a greenhouse gas, is leaking into the atmosphere. One might ask, “Why bother with methane, isn’t carbon dioxide the problem?” Well, according to the IPCC (https://www.ipcc.ch/), methane is 84 times more potent than carbon dioxide, which is clearly a bad thing for global warming. Methane is believed to be responsible for 25% of global warming and knowing who is emitting, when, and how much, would be a massive step towards reversing climate change. Since between 50 and 65% of total global methane emissions come from human activities, being able to identify and stop leaks is crucial to lowering greenhouse gases in our atmosphere.

Bluefield plans to specialize in methane gas detection and not try and solve all problems all at once and thereby reducing complexity. Further reduction in complexity is achieved by leveraging outside suppliers where applicable that complement the Bluefield plans. By reducing the complexity, Bluefield can focus on its core mission and specialty. Areas outside of detection such as the satellite parts, ground stations, the launch, and other services will be outsourced. This will allow Bluefield to quickly move through its development stages. Whereas it might take up to 10 years for a space agency like NASA, JAXA or ESA, to fund, design, test and launch a custom satellite, Bluefield aims to accomplish this as early as next year.

In fact, the prototype for the first microsatellite design has already been completed. Bluefield shortlisted several suppliers and the final selection will be made soon. The company is well on its way to testing its technology in orbit after completing both field tests and high-altitude balloon tests this year. By mounting its newly developed sensor on several backpack-sized microsatellites, Bluefield will be able to collect enough raw data to provide methane emission monitoring at a previously unthinkable level in terms of global coverage, high resolution and at a price point well below what is currently available.

Astronomers spot never-before-seen gravitational wave source from binary white dwarf stars

Posted by in categories: energy, physics, space

Astronomers have detected two stellar corpses whirling around each other, and they might be producing gravitational waves.

White dwarf stars are what become of stars like our sun after they run out of fuel and turn into leftover hot cores. For many years, researchers have predicted that there should be binary, or two-object, systems made up of white dwarf stars. According to general relativity, two such masses orbiting each other should emit energy in the form of gravitational waves, which are ripples or disturbances in the fabric of spacetime.

Extremely small magnetic nanostructures with invisibility cloak imaged

Posted by in categories: computing, nanotechnology, particle physics, space

:00000


In novel concepts of magnetic data storage, it is intended to send small magnetic bits back and forth in a chip structure, store them densely packed and read them out later. The magnetic stray field generates problems when trying to generate particularly tiny bits. Now, researchers at the Max Born Institute (MBI), the Massachusetts Institute of Technology (MIT) and DESY were able to put an “invisibility cloak” over the magnetic structures. In this fashion, the magnetic stray field can be reduced in a fashion allowing for small yet mobile bits. The results were published in Nature Nanotechnology.

For physicists, magnetism is intimately coupled to rotating motion of electrons in atoms. Orbiting around the atomic nucleus as well as around their own axis, electrons generate the magnetic moment of the atom. The magnetic stray field associated with that magnetic moment is the property we know from e.g. a bar magnet we use to fix notes on pinboard. It is also the magnetic stray field that is used to read the information from a magnetic hard disk drive. In today’s hard disks, a single magnetic bit has a size of about 15 × 45 nanometer, about 1,000,000,000,000 of those would fit on a stamp.

One vision for a novel concept to store data magnetically is to send the magnetic bits back and forth in a memory chip via current pulses, in order to store them at a suitable place in the chip and retrieve them later. Here, the magnetic stray field is a bit of a curse, as it prevents that the bits can be made smaller for even denser packing of the information. On the other hand, the magnetic moment underlying the stray field is required to be able to move the structures around.

3 Fun Space Games Play With Your Kids to combat isolation.

Posted by in categories: health, space, virtual reality
Space Related games to play with your kids to combat isolation.

So we are on month 3 of COVID19 here in Asia. We have had some time to figure out how to keep ourselves from going stir crazy. Playing some boardgames with the kids is a better alternative to youtube or xbox all day long.

I know that being stuck in side can be challenging. Going outside with your kids may not be a possibility if you live in a high density population area. So what do you do with your kids when they are stuck at home, getting stressed out or spending too much time online? Answer: Spend time with them.

Scholastic, the company that is known for educational fun books for kids, said that there many benefits for playing games as a family. If you bring out board games, the kid turn off the screen. You can have special time with your kids and allowing you to teach them about teamwork, patience, and how to win and lose gracefully. Board games can help benefit kids’ brains and language development.

  • Board games offer math skills like probability… but don’t tell them that.
  • They boost their language skills as they read cards and ask what words mean.
  • They sharpen your child’s focus by getting them interested in reading rules, looking at the play board and figuring out how to win.
  • They teach the value of teamwork. All for yourself doesn’t work very often in games. Kids learn that if they play dirty, other people adjust their strategy, and usually form alliances to counter a cutthroat player.
  • Strategy games are useful developing thinking skills. Working through problems, adjusting strategy to account for twists and turns is helpful.
  • Take your mind off things and easy anxiety. Looking at the news full time isn’t healthy. Especially kids don’t need to be exposed to all of the serious problems outside. Let them focus at home with you.
  • Show kids how to be a good loser (and winner). Winning is great. Playing in a way that everyone has fun is better. Kids will learn that is okay to fail in a game, because they can always play again and do better next time.
  • Unplug. Unplug. Unplug. To much screen time isn’t good for anyone. Let the eyes have a rest and let your and your kids brain unwind.
  • Set an example. Put down the phone and have a conversation with your kids. They will talk with you so much more when playing a game.

Here are a few games that we played during our first 3 months of being at home.
