The Infinite World

SpaceX successfully launched SN11 on 30 Mar 2021, did the 10Km vertical flight and switched to horizontal returned flight. But, exploded on the landing attempt. 4th successful flight to 10km, getting close to a successful landing.

 SpaceX Starship prototype SN10 launched and landed successfully on the evening of 3 March 2021 Wednesday, from the Boca Chica, Texas.  It went on to explode 8 minutes after landing on the ground. Still, it was a great success and a step closer to getting to orbit in the full configuration. The landing was beautifully controlled this 3rd time. Explosion probably due to fuel tank or engine system not fully shut down. Waiting to see the start of testing of the gigantic first stage. 

 SpaceX is currently preparing to launch SN10 after 2 rounds of static engine tests!!

 Things are happening much faster now with communication possible anywhere on Earth, but there are countries stuck in the bygone era.  There is nothing wrong if you do crave for money and the comfortable trappings that comes with it.

 28 Feb 2021 will be memorable day for Japanese marathoning! A new Japanese national record was established by 25 years old Kengo Suzuki, who ran 2:04:56. He ran the last 2.195km in 6min16sec.  A record 42 runners broke 2hours 10minutes. Yuki Kawauchi also pb in the same race, running 2:07:27 for 10th place.

 My pb for the marathon distance is 4hr 47min 26sec set at the SCSM 2014. I need to run a consistent 6min 48.72sec per km to break this record. It’s not a fast pace but I just have no confidence in my body to break it now.

 50MIN10KM is about running a distance of 10km in a time of 50 minutes by a human being. It is not a extremely fast time if you compared it to the men’s world record for the distance of 26min11sec set in 2020.  To achieve this time is equal to running 25laps of a standard 400m track, each lap in exactly 2min. Or running at a constant speed of 12km per hour. 

SpaceX has completed 5 successful launches since the start of 2021. The first stage did not manage to land on the drone ship during the last launch. 60 Starlink satellites were deployed during the launch.

 SpaceX successfully test flown SN9 to an attitude of approximately 10km, although it did not land as intended, on 2 Feb 2021 US time. The flip back could be 500-800m earlier and more thrust to stabilise and abit more vent control to bring the rocket back to vertical position. There was just too much power at the point where it hit the ground, it still had too much speed. 

It’s been growing by the days, it will be a very advance structure in the future or even perhaps now! It’s mysterious and huge, but looks empty right now. 48deg52.6S, 123deg23.6W. It is 1km by 1km and 59.5m deep, approximate weight is 10million tons. It is located at the above coordinates, no one knows who inhabited this place. It seemed to be built of a high technology material.  Apparently anything that gets too near it will be forced to back off on its own. There is no visible machine of any kind that is protecting it, but you just do not seems to get any nearer to it, no matter how fast you try to get near to it. Those who tried, seemed to skirt around it without even realising that they have done so.  Lately, there seemed to be couple of flying objects moving above the huge structure. Could this be the start of a autonomous existence of an entity free from any organised sovereign country? 

SpaceX prototype SN9 is taking its first flight very soon, probably to 10-12km height. It’s a question of control over the booster, they need to really fine tune the control of the descent speed to avoid crashing to the ground. 

The way forward for the human race is to stop fighting each other. Save the money to help the less well off, by giving them the much needed education.  Saying is so easy, but the selfish human will not listen. 

 A new year has begun, year 2021.  Human is still going nowhere, their selfishness made them fight again each other, do things that harm each other, harm their environment.  They are always caught up in their fights, never realised that they are actually fighting their evil half every single day.  They have been at each other’s throats for thousands of years and will continued to do so for who knows how long more, till the day they wake up from their long slumber.  Human always dwell in their emotions, which always end up wasting their time. It will take a great deal of effort to wake them up, as their evil self always stand ready to defeat them.  It’s a vicious cycle.....

Yuki Kawauchi achieved his 100th career sub 2:20 marathon at the 51st Hofu Yomiuri marathon on 20 Dec 2020, Sunday. He finished 2nd position with a time of 2:10:26. Congratulations to Yuki...!!!

SpaceX which already surpasses its previous best of 21 launches in a year in 2018, completed its 25th launch of 2020 on 11 Dec. The SXM7 mission launch a 7 ton broadcasting satellite for SiriusXM, from Florida. Another launch is scheduled for 17 Dec 2020, a NROL launch.

There is no doubt that SpaceX Starship will go from 12.5 km test flight to a 100km or more by the end of 2021. In the mean time, why not build a improved Dragon spacecraft to test out all the technology needed for a prolonged space flight?  The trip to the moon may only take a week or two only, but a Mars trip will take at least 6 months or more. Build a spacecraft to test out all the life support systems will speed up the actual Human capable Starship.  The test spacecraft can take a trip to nowhere, but maybe up to a million km away from earth. Human need to build up the knowledge in space travel, rather than jumping into something big and not tested. At the same time, meet up with new problem that will definitely surface on a long trip. A engine that need repair, a collapsed computer on board, how to treat a sick astronaut when you are 2.8million km away from the hospital? Yes, human need to accumulate the knowledge for long distance space travel. 

SpaceX starship prototype SN8 successfully launched on 9 Dec 2020 about 5 am Singapore time. The 3 Raptor’s engine ignited and lifted off from the ground and went up all the way until about 4 min plus of the flight and shut the engines and tipped over using small thruster along the middle of its belly, till horizontal and glided beautifully down to the surface again. Just before reaching the ground, the engines reignited again and flipped back up to vertical position for the landing. It did land but could not control the landing and sort of exploded, it did not explode and burn for a long time, as the smoke screen cleared only after about 45 seconds. It was a beautiful flight and is considered a successful flight of 6min42 sec. Congratulations to SpaceX...!!!! Way to go. Looking forward to the next test SN9!

SpaceX has completed 24 launches in 2020 up to 6 Dec 2020. 23 regular launches and 1 abort test for the crew mission certification. For a company, it has done so much more even compared to most space agencies! In fact, it has done a excellent job, who else can bring back a booster rocket from 70km up and reused it 7th times!

SpaceX Starship SN8 first high attitude test flight to 15km could happen any time from 4 Dec to 6 Dec 2020 from its Boca Chica site in Texas. This is the upper stage of the whole package, which also include the lower stage first stage called the Super Heavy. 

 Started my run quite late, about 7.20 pm. I started the run quite briskly, not my usual slow start. The route was from yck road to bishan park, I had to cross like 4 traffic lights, which slow down my pace. I reached the park in 16 min 1 sec, my pb for this stretch of 2.65 km is 14min40sec. Still feeling good, I continued with 1 lap around the park, was quite winded by the time I exit the park again. I still needed to complete the same stretch I took to the park. I started to reduce my pace, but I tried to just run at a reasonable pace till I reached yck road again. I eventually completed 9.05km in 55min42.6sec. If there is no need to tackle all the traffic crossing, I believed I can reduce the time taken by about 1.5 minutes.
