Research On Humans Adapting, Living & Working In Space — Colonel (ret) Dr. Samantha Weeks, Ph.D., Polaris Dawn, Science & Research Director

Colonel (ret) Dr. Samantha “Combo” Weeks, Ph.D. is the Science & Research Director, of the Polaris Dawn Program (https://polarisprogram.com/dawn/), a planned private human spaceflight mission, operated by SpaceX on behalf of Shift4 Payments CEO Jared Isaacman, planned to launch using the Crew Dragon capsule.

For about 9 months, Elon has been suggesting that Booster 4 with Starship 20 on top of it would do the first orbital test of Starship.

The big question was how safe would it be to launch with 29 Raptor engines at once? A lot of people were talking about Russia’s N1 rocket which failed in all four attempts with its 31 engines, causing one of the world’s largest nonnuclear explosions and killing over a hundred people in the process. The most Raptor engines that have ever been static fire tested at once is 6. It would be very difficult to rebuild the Starship tower if it was destroyed. Easily ten times as hard as building another Starship and booster.

Note that using so many engines is not impossible. For example, the Falcon Heavy launches with 27 engines and all its launches have been successful so far. The problem is that the Raptor is the world’s first full-flow staged-combustion-cycle engine and SpaceX has not perfected it yet. For example, the only Starship which successfully landed from a medium-height test almost missed the landing pad and was on fire when it landed. (All other medium-height test Starships exploded, one before it even hit the ground.)

The charismatic Zhurong rover has left its mark on Mars.

That’s over double the original expected launch cost.

NASA’s Space Launch System is supposed to ferry astronauts to the Moon, but at an estimated $4.1 billion per launch, it may be doomed before it ever gets off the ground.

The path back to the moon is long and fraught with danger, both in the real, physical sense and also in the contractual, legal sense. NASA, the agency sponsoring the largest government-backed lunar program, Artemis, has already been feeling the pain on the contractual end. Legal battles have delayed the development of a critical component of the Artemis program – the Human Landing System (HLS). But now, the ball has started rolling again, and a NASA manager recently reported the progress and future vision of this vital part of the mission to the Institute of Electrical and Electronics Engineers at a conference.

Kent Chojnacki is the manager of NASA’s Systems Engineering & Integration Office. He recently gave a presentation entitled Human Landing System. While it only ran to six content slides, he provided some more details into how the agency is arranging its work with future contractors developing the part of the Artemis program that will take astronauts down to the lunar surface.

CAPE CANAVERAL, Florida — The first mission in NASA’s Artemis moon program is set to roll out to the launch pad today (March 17).

SpaceX CEO Elon Musk has officially confirmed his prediction for when he thinks humans will finally land on Mars. But it might be too optimistic.

For the second time ever, SpaceX has used Starbase’s ‘Mechazilla’ tower and arms to stack a Starship upper stage on top of a Super Heavy booster.

This time around, though, SpaceX clearly learned a great deal from its second February 9th Starship stack and was able to complete the stacking process several times faster on March 15th. During the second attempt, depending on how one measures it, it took SpaceX around three and a half hours from the start of the lift to Starship fully resting on Super Heavy. With Stack #3, however, SpaceX was able to lift, translate, lower, and attach Starship to Super Heavy in just over an hour.

Oddly, SpaceX managed that feat without a claw-like device meant to grab and stabilize Super Heavy during stacking operations. For Stack #2, all three arms were fully in play. First, a pair of ‘chopsticks’ – giant arms meant to grab, lift, and even recover Starships and boosters – grabbed Ship 20, lifted it close to 100 meters (~300 ft) above the ground, rotated it over top of Super Heavy, and briefly paused. A third arm – known as the ship quick-disconnect or umbilical arm – swung in and extended its ‘claw’ to grab onto hardpoints located near the top of Super Heavy. Once the booster was secured, the ‘chopsticks’ slowly lowered Ship 20 onto Booster 4’s interstage and six clamps joined the two stages together.
