On the same day as the launch of Artemis I to
the Moon, Astrobotic issued this
showing the Peregrine spacecraft being
readied for shipment.
from Reuters shows that this is the debut of the
Vulcan rocket. This line is priced at about
$110 million per launch. When successful it
will offer an American made alternative to the
Russian engines commonly used in the industry.
The delay from end of 2022 was at the request of
Astrobotic.
shows the Mass Properties and Vibe
Test. The former weighs the vehicle and
determines the location of the Center of Mass and
various inertial properties. These are needed
for the attitude control system. The second
test is to shake the hardware to test its strength
for withstanding launch.
The rocket stack
used for our launch will be a Vulcan booster
powered by two BE-4 engines from
Blue
Origin, and the upper stage will be a
Centaur V. These are new motors that run on
Methane (LNG), and have more thrust that the Space
Shuttle Main Engines. Once operational, they
will replace the ones that are normally bought
from the Russians, and that will be very good in
these uncertain political times.

First Stage (Booster) Tanking Test
The tanking system of this brand new rocket design
was tested at launch pad LC41 and described in
this
update. A nice video summarizing the
tests and a glance at the payloads is
here.
April 2023 -
Upper Stage Tank Test
This
video shows a explosion during a test of the
Centaur V upper stage tank. This may be
cause for delay. The launch window will be
in monthly intervals due to the Lunar flight
trajectory. Indeed in early May, we received
an email update that launch would be delayed from
the May 2023 date.
June 2023 - BE-4
Test Fire
On June 7 2023, the twin BE-4 engines running on
Methane were test fired successfully on the launch
pad. This is clearly an important milestone
to launch. In the next step, I would expect
to next hear that Astrobotic can ship Peregrine to
the Cape for launch.
October 26 2023 -
Installing the Booster Stage
ULA posted this sequence on their
Twitter
page to show the Booster with the twin BE-4
engines being raised onto the pad.

Booster being raised onto the pad.
October 27 2023 - Shipping to the Cape
After a long delay due to the upper stage
issue on the Centaur, the Peregrine spacecraft was
loaded onto a truck and shipped to the Kennedy
Space Center.
November 2023
We saw the booster being raised onto the
pad in the image above, and ULA released an image
of the Centaur V upper stage this month. It
gets stacked on top of the booster, and then
Peregrine will be stacked on top of that. At
the pad, the booster will be ignited first, and
carry the whole stack aloft. It will then be
dropped, and the upper stage takes over pushing
Peregrine to the Moon.

In this same month, Astrobotic sent out
invites for the launch party. It also
included a link to the
info
packet. Note that the Aruba sand will
be sent via the Moonbox program. The landing
spot has been changed from Lacus Mortis to "
Gruithuisen
Domes". This area was named after the
German astronomer
Franz
von Gruithuisen.

Also this
month, NASA announced that two Goddard-led
development teams would fly on
Peregrine. These are
the Laser
Retroreflector Array (LRA) and Peregrine
Ion-Trap Mass Spectrometer (PITMS).

December 2023
Early in this month, they performed a Wet
Dress Rehearsal (WDR). This is where the
rocket is tanked to check for leaks. As you
can see here with the tweet from Tory Bruno (ULA
President) it all went well and launch date is now
set for Jan 8, 2024.

Later this same month, Astrobotics sent out
an
update showing the spacecraft mounted onto
the payload adapter. The update also
disclosed that the anticipated landing date on the
Moon will be February 23, 2024. This payload
adapter is custom made for this spacecraft so that
it can be bolted onto the Centaur V upper stage.
This
video
released December 22, 2023 shows the entire
rocket complete and ready for launch.

Here you see Peregrine encapsulated in its
fairing being
stacked onto upper stage.
Launch!
