I am now in the third week of my annual February birthday fund-raising drive. The first two weeks were good, but not record-setting.

 

There are still two weeks left in this campaign however. If you have been a regular reader and a fan of my work and have not yet donated or subscribed, please consider doing so. I take no ads, I keep the website clean from pop-ups and annoying demands (most of the time). Thus, I depend entirely on my readers to support me. Though this means I am sacrificing some income, it also means that I remain entirely independent from outside pressure. By depending solely on donations and subscriptions from my readers, no one can threaten me with censorship. You don't like what I write, you can simply go elsewhere.

 

You can support me either by giving a one-time contribution or a regular subscription. There are five ways of doing so:

 

1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.

 

2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
 

3. A Paypal Donation:

4. A Paypal subscription:


5. Donate by check, payable to Robert Zimmerman and mailed to

NASA: The flight plan for Dream Chaser Tenacity’s first demo mission to ISS

NASA today provided a detailed description of the flight plan for the first demo ISS mission of Sierra Space’s first Dream Chaser reuseable mini-shuttle, dubbed Tenacity, now targeting some unspecified date in 2024.

It will carefully approach ISS, testing its maneuvering and rendezvous capibilities, and then be grabbed by the station’s robot arm to be berthed to the station.

On its first flight to the International Space Station, Dream Chaser is scheduled to deliver over 7,800 pounds of cargo. On future missions, Dream Chaser is being designed to stay attached to the station for up to 75 days and deliver as much as 11,500 pounds of cargo. Cargo can be loaded onto the spacecraft as late as 24 hours prior to launch. Dream Chaser can return over 3,500 pounds of cargo and experiment samples to Earth, while over 8,700 pounds of trash can be disposed of during reentry using its cargo module.

On this first demo flight it will remain docked for 45 days, and then land on the shuttle runway at Cape Canaveral.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

    Let us see if this works better than the Starliner. I certainly hope so.

    Has anyone ever done a trash dump re-entry before? It would be interesting to see it as a night side event, like a giant sparkler in the sky!

    There have been dozens of ISS trash dumps before. The European ATVs, the Japanese HTVs, the Russian Progresses and the U.S. Cygnuses did/do trash incineration re-entries at the end of every mission. Soon, they will be joined by the Dream Chaser’s Shooting Star modules while the spaceplane parts of Dream Chasers join Crew and Cargo Dragons in providing intact downmass landing capability from ISS.

  • Spectrum Shift: The Russians have been de-orbiting Progress freighters filled with garbage for decades. The various partners on ISS have done the same.

    Most occur in remote regions of the Pacicit, but if you do some smart web searches, I am sure you can find a few examples where someone got footage.
