SpaceX to launch last lot of Falcon 9

One of the last lots of Falcon 9 rockets of the SpaceX company has been shifted to the Company’s California launch pad. This is mainly done to initiate a recovery attempt which is slated to take place on Tuesday.

Although the company has made many efforts in the launching of new versions of Falcon 9 Block 5 rockets, still some of the older versions are waiting for their last lap of launching to space. The latest version of the Falcon 9 Block 5 rocket has excellent features of reusability and has been pretty successful in launching the Bangabandhu-1 which was the first satellite of the Bangladesh Government. At this very moment, there are still four rockets which will be launched which involves the sooty Falcon 9 first stage.

This particular rocket had faced troubles while landing when it had launched the mysterious Zuma mission in the year of 2018 and in January. This was stated to have re-entered the earth’s atmosphere minutes after it reached the orbital position. The purpose was considered to be a failure, and the entire blame was given to the Northrop Grumman who had designed the payload adapter as well as the deployment mechanism.

In spite of this problem, the same rocket booster of the SpaceX company which had lifted off the much controversial Zuma mission is all set to load a new payload into space from the launch pad of SLC-4E. This launch pad is situated in Vandenberg Air Force Base. The number of this particular rocket is B1043 which is scheduled to position itself within the orbital position for the second time carrying along with it seven satellites.     Five of such satellites belong to the iridium variety, and the remaining satellites are lifted up for specific other scientific mission. Such mission is known as the GRACE-FO.

As for the company is concerned it will be scrapping off B1043 Falcon 9 version after it completes the job of positioning GRACE-FO into its desired orbit. This shows that the company would be using the last possible launching activity. At the current situation, experts have advised that it won’t be prudent to reuse the flight for than two times after refurbishing them properly. However, the company is pretty determined the reuse the older versions till the new translation captures the market appropriately. The Falcon 9 Block 5 version will be re-used 10 to 100 times with minimum repairs and maintenance.

OneSpace vs. SpaceX – Shu Chang Interview with CNN Money

Now that the CEO of OneSpace did draw a parallel between his company and that of SpaceX, we should take a close look at the two.  During an interview with CNN Money, Shu said that the two are similar, many aspects illustrate that the duo is two sides of the same coin. We are about to take a look at them. Read on for a detailed comparison as well as contrast.

The two companies use different technologies. While OneSpace looks forward to building rockets that can lift big satellites into space that is already a reality when we refer to SpaceX. Nevertheless, both of them have a dream of having human flights in the future.

When it comes to the rockets that the two make, there is a difference as well. That of the Shu’s company has a height of 30 feet tall. In addition to that, its carrying capacity is around 220 pounds into the orbit. Compared to those made by SpaceX that is like a drop of water in the ocean. SpaceX’s first rocket, the Falcon 1, had a height of 70 feet. The Falcon 9 makes the distinction crystal clear. Its height is 230 feet, and it can carry a maximum weight of 50,000 pounds. 

As far as the fuel each one of them uses is concerned, here is a dissimilarity. The one of OneSpace is in solid form. On the other hand, that of the SpaceX is liquid. Let us differentiate the two types. Each one of them has merit and a demerit as shown below. The solid one is not only relatively stable but also easy to create. However, they pay a higher cost later on. It becomes impossible to reuse a rocket booster once you launch it. For the liquid fuel, the vice versa is true beyond any reasonable doubt.

From the interview, OneSpace is following the footsteps of SpaceX regarding funding. They want to run it as a private organization. At the same time, it wishes to receive funds from the government. How is that similar to the case of SpaceX? Elon Musk runs the company privately. However, they get contracts from NASA year in year out. Therefore, they get to work with the government and also serve its additional clients. At one point, they were about to experience an early collapse.

Considering the above, OneSpace has a long way to go. Dreams are valid, and OneSpace has a right to do that. We wish the company all the best as they rise to the top.

NASA’s safety advisory panel declares SpaceX’s dicey rocket fueling process feasible

NASA’s safety advisory panel discussed SpaceX‘s proposal of loading rocket propellants when astronauts are aboard. It seems to be a reasonable option in place of the group. Members of the Aerospace Safety Advisory Panel have maintained that loading crew the even before fueling is done is viable. However, the possible hazards need to be controlled.

According to Brent Jett (Retired Captain) of the panel, if the controls can be decided on and implemented for causes of hazard and situations which could end in an emergency, loading and going is an option to be considered. Boeing Co. and SpaceX have contracts from NASA contracts to manufacture crew capsules. These will be used for the transportation of astronauts to ISS (International Space Station). SpaceX and Boeing are supposed to carry out test flights in August and flight tests (with crew) another few months later.

The rocket fueling process of SpaceX has been subjected too much deliberation since the issue cropped up during a meeting in the House Committee on Science, Space and Technology. SpaceX makes use of liquid oxygen (super chilled). This maximizes the amount which can be contained in the tank, thus increasing the rocket’s power during liftoff. The super cold temperature implies that the fuel must be kept right before the launch.  Hence in case of crewed flights, astronauts would already be onboard.

A Falcon 9 rocket of SpaceX had exploded on a launch pad in 2016. The rocket propellant was being loaded then. This explosion damaged the pad and destroyed the SpaceX’s communication satellite. On further investigation, SpaceX discovered that the tank had most likely failed since the chilled liquid oxygen had collected in some buckles used onboard the vehicle. “Breaking fibers or friction” had then ignited the oxygen present in the carbon overwrap, according to the company. SpaceX redesigned its pressure vessels. NASA then began an intensive test program to examine the vessels’ behavior under cold temperatures.

Previously, astronauts boarded the vehicle only after the propellant had been loaded. The Safety Advisory Panel had previously warned about the method proposed by SpaceX in a previous report.  Saying, according to the panel, the associated risks of this method had not been understood. However, SpaceX believes that the faster fuel-loading process is preferable and safer when compared to traditional methods as it lessens the time of the crew’s exposure to a fuel-loaded rocket. It has also created an abort system to carry astronauts to safety, if an explosion takes place.

More Speedy Flights are accompanying New Satellite Tracking Technology 

The organization that do offer the U.K aviation authority service is going to take a ten percent in Aireon LLC, which is a United States firm that is creating a satellite-based following framework and will offer business administrations to controllers beginning from one year from now. Aireon has plans to make utilization of 66 Iridium Next Satellites in the low Earth circle to track an airplane. Iridium has 50 in a circle as of now, 47 of which are working. Every one of them conveys gear to offer airplane position information to controllers. Iridium intends to dispatch five more satellites. This will finish its full system not long from now. Aireon has said that 70% of the World’s airspace needs satellites attaching or aircraft reconnaissance scope. This incorporates most seas and portions of Africa and Latin America. This has subsequently left most controllers helpless before pilot correspondences to monitor flying machine flying those zones. The organization went ahead to state that its innovation will take into account better-improved flight ways, thus sparing fuel and time while lessening the detachment between airship. This will henceforth mean more flights in swarmed places, for example, North Atlantic. Flying machine that is crossing that lake reports their positions at regular intervals as they fly set courses, keeping no less than 40 miles separated. Aireon has said that its satellites based framework will take into consideration fifteen miles of detachment on maritime courses and this will make space for more planes. McLean, which Aireon has most shares, which is the air specialist co-op for the country, with little stakes that are held by Iridium and via air movement benefits in Ireland and Denmark? NATS, as U.K benefit, is known, will burn through $69 million to be part of co-proprietor of the new administration. NATS will be required to one of the primary clients of the Aireon framework. The private airport regulation organization, once in the past known as National Air Traffic Services took care of around 80 percent of trans-Atlantic movement. The activity is relied upon to increment to right around 800,000 by the year 2030. A dominant part of the worldwide flights as of now do transmit their positions by means of an innovation dubbed ADS-B, which can without much of a stretch be followed starting from the earliest stage. The United States Federal Aviation Administration has introduced a ground-based following framework for the ADS-B and test are set to begin this year.

Evidence of Water Plume on Jupiter

The reality of a giant plume of water vapor wafting from Jupiter’s potential of supporting life in moon Europa just got a lot. The NASA’S Hubble Space Telescope has been able to spot signs of plume several times over the past half-decade. The measurements were very close near the limits of the powerful instruments sensitivity. Currently, the researchers, have reported a new study that the NASA’s Galileo, Jupiter probe, that does orbit the planet from the year 1995 to the year 2003. There has also been the detection of a likelihood of Europa Plume during a near flyby of the icy moon in the year 1997. The fresh analyzed Galileo data does give a more supporting independent evidence that there may be a plume on Europa. This was said by the lead author Xianzhe Jia, who has been serving as an associate professor at the University of Michigan. This has been very pleasing news, especially for the astrobiologists. If it turns be indeed true that the plume has water, then it can be able to offer a way for the spacecraft to taste the Europa’s buried ocean of the liquid water without necessarily having to touch down on the moon. 

NASA is currently working on a goal that can help to realize that. At 1,900 Miles wide, Europa is smaller when compared to the Earth’s moon. Researchers think that the Jovian satellite contains a huge amount of liquid water. They estimate that there is a likelihood that this could be twice as much as the water of the Earth. This is in a very huge and deep global ocean sloshing below the objects ice shell. The ocean seems to be closely in contact with the Europa’s rocky core that does enable a wide variety of fascinating and complex chemicals equations. There are very many astrobiologists that consider Europa as being among the solar system’s best bets to be able to host the alien life.  This is in inclusion with the icy Saturn moon Enceladus that also does contain a subsurface ocean. Close to Enceladus ‘s south pole, there are over 100 single geysers that do continue to blast water, ice, organic molecules and other materials which are very far out in the space. There is a likelihood that this plume stuff will come up with Saturns’ E ring. A scientist does think that the geysers materials that are coming from Enceladus’ ocean, flying through the moon will make a way of searching for various signals of life on Enceladus without necessary touching down. 

SpaceX Falcon 9 Block 5 returns home

SpaceX’s latest version of the http://www.spacex.com/falcon9 has returned on the Earth’s surface after it took off on May 11 with the Bangabandhu-1 satellite. It has just initiated the long and seasonal campaign regarding the more advanced space exploration process. The booster which has the number as B1046 seems to be in perfect shape with not much of a dent after a high-level energy entry into the earth’s atmosphere.

After separating from the rocket’s second stage which carried the Bangladeshi satellite into the geostationary orbit, B1046 reached a maximum height of 110 km before it started to re-enter into the earth’s atmosphere. The rocket whipped through at a speed of nearly 2 kilometers per second and finally completed a soft landing at a location which was 500 miles off the Florida coast. It was the 25th successful landing of the Falcon 9 booster, and the B1046 made the occasion a memorable one. It adorned the large black sections of the newly designed Space X rocket with its latest thermal protection system, which is actually among the number of improvements that are made with the Block 5.

Although it is not visible, the main improvement has been made at the base of the first stage octaweb which is now put together will bolt instead of welds. It has taken the form of a highly developed heat shield around the so-called nine Merlin 1D engines. One of the recovery engineers of the Falcon 9 rocket showed with many interests about the various improvements that were made to the rocket before its first launch to space. 

Elon Musk, the owner of the company, has assured of quick reassembling and maintenance of the rocket. If his words prove to be true, then B1046 will be refurbished and flow to the space many more times and thereby bring about more glory and pride for the company. However, the company will also be cautious in its process to check the inside technical issues very thoroughly before giving a green signal to the authorities for the next launch preparation. The company is in no moods to generate any hiccups before any further launch.

At the same time, this mission has also paved the way for another routine purpose for the company involving SpaceX’s robotic stage-securing robot which is nicknamed Roomba. The custom built robot is specially developed to ensure the safety of SpaceX’s recovery crew by keeping them on the accompanying vessel.

China Gets Ready to Launch Chang’e-4 Relay Satellite

China is ready with its next satellite launch plan. The country is looking forward to launching a relay satellite called Queqiao to Lagrange point, the second Earth moon, on May 21. The Queqiao satellite is part of China’s Chang’e 4 mission to the far side of the moon. 

It is a notable and essential fact that Chang’e-4 is the backup to the earlier Chang’e-3 mission. In the year 2013, the Chang’e-3 mission has sent a rover and lander on Mare Imbrium. After achieving this unparalleled success, the Chang’e-4 lunar-craft has been prepared to land on the far side of the moon. The orbital duration of the moon does not let the lunar far side face the Earth. Hence, a relay satellite was needed for easier communication.   

The Queqiao (of Chang’e-4 mission) satellite will be launched from Xichang Satellite Launch Center. The Xichang Satellite Launch Center is located in the southwest part of China. The 3-day launch window will open up on 21st May. The chief purpose of Queqiao satellite is to relay telecommands (from the ground) to the Chang’e-4 lunar spacecraft. It will also be helping in conveying data back to our planet. The satellite will be using S-band for transmitting data, and on the other hand, it will be utilizing x-band for establishing communication with rover and lander. Presently, the landing point for Queqiao satellite is supposed to be the Von Kármán crater. 

Ian Crawford, the professor of planetary science and astrobiology at Birkbeck, University of London, stated that the launch of Queqiao satellite is quite exciting as it will happen for the first time that any spacecraft will be launching successfully on moon’s far side. 

There is an interesting fact related to the Queqiao satellite. In fact, the name of this satellite is inspired from folklore tale. It is being told in the folklore tale that there were two lovers who reunited just once a year. They used to reunite when the Magpies created a bridge across the Milky Way. The word Queqiao means bridge of magpies. It is being expected that the Queqiao satellite will be orbiting far beyond the moon at the Lagrange point about 65,000 kilometers. Interestingly, the launch of two microsatellites will also take place along with the start of the Queqiao satellite. These two microsatellites will provide help and support in doing scientific research. The names of two microsatellites that will be launched with Queqiao satellite are “Longjiang-1” and “Longjiang-2. 

Figure Out Virgo – The Earth Goddess

Gazing at star constellations and imagining the figures hidden in them is a childhood play which all of us do even after getting matured. This particular news piece is for those who want to see a star constellation more explicitly. Yes! The upcoming Mother’s Day will indeed be unique as the Earth Goddess Virgo appears comparatively brighter in the sky. 

There are many constellations which are quite big. Virgo is also one prominent constellation. It is in fact, the second largest constellation. The Virgo constellation is also unusual because it is the only female figure among all zodiac constellations. The female figure hidden in the Virgo constellation is often associated with Mother Earth. Hence, what would be a better way to celebrate Mother’s Day than watching Mother Earth in the sky!

The stunning Virgo constellation can be observed in the evening hours. It includes most of the area of the southern sky. Most of the stars of this constellation are quite dim, but stargazers, as well as sky-observers, create a perfect pattern that matches the stars appropriately to receive a figure of a young female having a shawl upon her shoulders. The beautiful figure of Mother Goddess portrayed in the Virgo constellation is compared with few other goddesses including the Greek Goddess of Justice called Astraea and also with Demeter Goddess. The Virgo female is imagined to hold a spike of wheat in her hand. This spike can also be noticed clearly with the female figure when you watch the vast constellation called Virgo. 

As mentioned earlier, the Virgo constellation is one of the principal constellations in all the eighty-eight constellations which are presently identified and observed in the sky. While Virgo is considered the second largest among these constellations, the exciting fact to mention is that the largest constellation lies just below the Virgo.  The most extensive constellation that lies near Virgo is called Hydra- the water snake. It can be noticed from east to west directions of the sky. The underlying reason behind the most significant size of this constellation is its unusual length which keeps stretching through many nearby stars. 

Watching the Virgo constellation in the sky will indeed prove to be a delightful event as it will appear on Mother’s Day. So do not forget to watch it with your mother and the entire family. Set your schedule for viewing this natural delight. 

NASA is sending a Helicopter to Mars 

NASA has said that it will include a little self-decision helicopter in the forthcoming Mars 2020 rover mission. The craft will be tested for 30 days. When it reaches the Red Planet to have the ability to show the sensibility of development over the Martian surface with a heavier than an airplane. The NASA manager by the name Jim Bridenstine said that the association had had a decent pattern of turning into the pioneer in a lot of advancements. He said that the likelihood of the helicopter flying the skies of another planet is to a great degree empowering. The Mars Helicopter holds such an excellent measure of assurance for the future science and investigation mission to Mars. 

The development of the Mars Helicopter started in the year 2013 at the NASA’s Jet Propulsion Laboratory (JPL). The helicopter measures 4 lbs. Its size is equivalent to that of a softball. It will convey Sun-controlled cells to empower in the light of the sun and a warming instrument to have the ability to endure through the frigid nights on the Red Planet. It has two sharp edges which will turn at around ten times the rate of a helicopter’s front lines on Earth. This will help it to have the ability to remain up high in Mars’ this condition. To have the ability to make it fly at the low ecological thickness, they investigated everything, making it as light as they could while meanwhile ensuring that it is strong and effective meanwhile. 

Mars 2020 has been intended to dispatch in July of that year on United Launch Alliance’s Atlas V rocket from Cape Canaveral Air Force Station in Florida. The mission should have the ability to get in contact at Mars in February 2021. The rover which has six wheels will look for the signs of the viable. They will go further and examine the Red Planet with a whole of 23 cameras. A mouthpiece and a drill to gather tests. 

The Helicopter will go to Mars connected with the Rover’s belly pan. Once the rover can accomplish the planet’s surface, it will then place the helicopter on the grounds and after that move to a secured position to exchange the orders. The controllers on Earth will then direct it to take its first free flight. The helicopter will endeavor up to five flights, going more far off and after that working for longer each time. It will then have the ability to move to 10 feet and float around 30 seconds. The Mars Helicopter has been seen as high risk and furthermore as a high reward venture.

Debris in space piles up to pose a risk – too much junk floating in space

The sky might be filled with stars, but then it has plenty of garbage as well. Humans beings have launched lots of satellites into space (around 1,700 operational space crafts are orbiting our planet), and every satellite does not come back to earth. Lots of them continue to speed through the sky long even after scientists have lost contact. It might lead them to collide with one another and crumble to pieces. NASA has come to estimation that there are about 23,000 pieces of space remnants which are more significant than 10 centimeters. Another 500,000 pieces are larger than 1 centimeter and around 100,000,000 bigger than 1 millimeter.

A metal piece as small as a sesame seed would seem harmless however even such minuscule bits pose a high risk. Tiny flakes of paint have chipped off the International Space Station’s thick windows, which moves close to menacing hunks of space debris. That is how fast garbage can runs. 

As the speed of such junk is more than that of a bullet traveling at 250 miles an hour, a sub-millimeter piece of junk poses a risk to astronauts conducting spacewalks outside the International Space Station. The debris can even create a hole in the spacecraft whereas larger debris is capable of completely crushing a satellite.

As per J.D. Harrington, a NASA public affairs officer, space debris is a real threat. Due to ongoing activities, the problem is likely to get aggravated and might create complications for space projects in the future.

Even though NASA has no plans to conduct a clean-up, the agency is trying to keep the problem from getting worse by seeing to it that ensuing missions have a clean-up arrangement in place. It includes disposing of space crafts which are longer operational or any parts that they might eject. 

Other solutions are being worked upon at the moment. In the 2017 European Conference on Space Debris, scientists considered shifting the real junk to higher orbits. It could then be captured by using capturing nets, magnets or harpoons. The International Space Station is planning to start a test project this month named the RemoveDEBRIS, which will be able to catch pieces of artificial junk before they get burned out. 

One thing to note is residents on Earth are not at any risk from space debris. Junk does fall down but then it usually burns up or breaks down, and the remnants are practically harmless. Since water bodies cover most of Earth, chances of a human being getting hurt are slim.
