Another launch of Starlink satellites and expected crash of Chinese rocket.

Look at the contrast between private-sector space exploration in the United States and government run space exploration in China.

5/9/21 – Amy Thompson at Space.com – SpaceX launches 60 Starlink satellites in record 10th liftoff (and landing) of reused rocket –  On 5/9/21, SpaceX put another load of 60 satellites into orbit, increasing the constellation of Internet-providing satellites.

Of note is that this is the 10th launch and recovery of this particular Falcon 9 rocket. That is the highest number of reuses yet of any in their fleet.

The goal, announced three years ago, is to fly each booster 10 times before major refurbishment and ultimately get up to 100 flights out of every booster.

Amazon is developing its own low Earth orbit satellite system to provide Internet connectivity across the planet. They are calling this Project Kuiper.

4/19/21 – Ars Technica – Amazon’s first Internet satellites will not launch on Blue Origin rockets – Some background to start the discussion.

In addition to Amazon, Jeff Bezos also owns a rocket company developing spaceships. It is called Blue Origin. They are developing New Glenn rocket as a lift vehicle. Article says first flight for New Glenn is not expected until fourth quarter of 2022 with likely slippage to 2023.

Big announcement covered in this article is Amazon announcing they will use the Atlas V rocket from United Launch Alliance for the first nine launches of their satellites.

SpaceX uses recycled rocket and recyled capsule for launch to space station.

A previously used Falcon 9 rocket and Dragon space capsule lifted four astronauts to the ISS.

4/23/21 – Science Alert – In a Huge First, SpaceX Just Launched Astronauts to the ISS on a Recycled Rocket – In their third flight to the International Space Station, SpaceX used a Falcon 9 rocket and Dragon capsule that had both previously been used. This is a big deal in terms of reducing the cost of space travel.

Along with the two previous flights this ends the American reliance on Russian lift vehicles to get crew to the space station.

SpaceX successfully recovered the booster. Again. They sent out a tweet saying this is the 80th recovery of a rocket. Very cool.

With these four astronauts (one from France and one from Japan) on board, there will be 11 people on ISS, which is a record. Another crew will return on the Dragon in a few days.

The crew:

Another SpaceX launch increases Starlink constellation to over 1,300 satellites as OneWeb builds their constellation.

Starlink Mission (3/14/21) by Official SpaceX Photos is licensed under CC BY-NC 2.0

Launch by SpaceX put another 60 satellites into orbit, bringing the constellation of Starlink communication satellites to over 1,300. Launch by OneWeb put another 36 of their satellites in orbit for total of 146.

SpaceX and OneWeb are both making progress on developing a constellation of satellites which will provide Internet connectivity across the planet. Discussion of OneWeb’s progress follows description of SpaceX’s launch.

Oh, by the way, after reading this post I am confident you will agree that the future is so bright we ought to wear sunglasses all the time.

Missed the live broadcast so watched the archived copy. SpaceX put another 60 Starlink sats into their constellation which will provide worldwide internet access. Link to video of the launch is at the end of this post.

Previous missions lifted 362 satellites, so adding these 60 makes 422 by my count.

This is the fourth flight for the booster and the second flight for one of the fairings.

50th successful recovery of a SpaceX Falcon 9 booster

Starlink Mission on 1/6/20 by Official SpaceX Photos is licensed under CC BY-NC 2.0  – A carefully observation will show the payload fairing reveals this not a Dragon capsule, but the photo provides a superb nighttime view.

Overnight SpaceX successfully launched a Falcon 9 booster with fully loaded Dragon capsule on a Commercial Resupply Service mission (CRS-20), lifting supplies to the International Space Station.

This specific capsule already has been to ISS twice. This will make its third trip up and third recovery.

Successful recovery of this specific Falcon 9 booster back at Cape Canaveral marked the 50th time that SpaceX has recovered a booster. Astounding.

This launch was at 10 minutes before midnight, resulting in quite different visuals than a daytime launch. You can watch the launch, recovery of the booster, deployment of the capsule, and deployment of the solar panels here:

Two launches in three days. Behind the Black provides a tally that year-to-date launches are 6 for US companies, 3 for China, and 1 each for Arianespace, Russia, and Japan.

SpaceX launch of Dragon lifting 60 communication satellites

Watched the recorded video of SpaceX’s launch of 60 more Starlink satellites from this morning. This is the fifth launch in the Starlink mission. After the fourth launch there were 182 sat, with 2 on first launch and 60 on each followup launch. Sixty  more on this launch brings the total in orbit to 242 by my count. Eventually the Starlink constellation will have 1,584 sats at a 341 mile altitude.

Video of the launch:

Just a few days ago we celebrated the 50th anniversary of Apollo 11 landing on the moon. What an astounding accomplishment and what a joy to remember. Take a look at the grainy views of the launch and walk on the moon mentioned in immediately previous post.

Check out the SpaceX Commercial Resupply Mission yesterday, 7/25/19. CRS-18 carried about 5,000 pounds of supplies and experiments to the International Space Station. In four weeks about 3,300 pounds of cargo will be returned to earth.

The mission press release says this is the third time this Dragon capsule has flown, which is a new record for reuse.  This is the second time this particular Falcon 9 booster has flown. The booster was successfully recovered.

The announcer on the broadcast said this is the 44th successfully recovery of a booster.

Sounds from the Falcon Heavy launch

Behind the Black points us to a report of What the Falcon Heavy launch sounded like.

What a treat it must have been to watch from miles away.

Using special stereo mikes, the recording catches the clicks of many nearby cameras before being overwhelmed by the rocket sounds.

Listen carefully for the multiple sonic booms from the boosters returning to earth. Each booster gives off a boom from the engines, then the landing legs, and then the directional control arms. So 6 booms expected. Sound track wave form shows echos, but one overlapped, so there were 5 booms from each booster.

Astounding, all the way around.

Also Behind the Black provided Update on Falcon Heavy core stage landing failure.  Turns out that two of the three engines scheduled to fire, slowing the descent, did not do so. Core booster missed the landing barge by around 300 feet.

BtB says this is why one runs experiments. Find out what doesn’t work, figure out the reason, and fix it.

Successful test of Falcon Heavy

SpaceX’s test of their three booster, 27 engine rocket was an astounding success. The three side-by-side Falcon 9 boosters worked perfectly together. The two side boosters successfully separated, which I think is the highlight of the test.

Both of the side boosters were recovered. See astounding photo above.

The payload was successfully lifted into the Van Allen radiation belt and continued to operate. Apparently that is a major milestone (my little brain doesn’t understand why that was a tremendous deal to NASA).

Update on Chinese space vehicles

A few fun articles on the Chinese space program.

10/15/17 – Behind the Black – China’s first test space station, Tiangong-1, is out-of-control – The Chinese space agency said they have lost control over the “Heavenly Palace” space station. Its orbit is decaying and it will likely reenter the atmosphere and burn up in the next several months. Most of the station will burn, but there will likely be chunks as large as 200 pounds hit the ground.

(Hat tip to Behind the Black for the next two articles.)

10/18/17 – GB Times – China’s Tiangong-1 space lab will soon reenter the atmosphere, but there’s no need to panic – Disclosed reason for the “Heavenly Place” space lab not being able to maintain orbit is a battery charger failed, thus meaning the batteries couldn’t be charged.

Current guess is perhaps the last half of January for reentry into atmosphere, where most of the 8.4 ton spaceship will burn up.

10/17/17 – GB Times – China progressing with work on new medium, heavy, and super-heavy Long March launch vehicles – Articles says China is working on several new rocket designs.

New models include the Long March 8 and Long March 9.  Some stats:
